Activating and deactivating LTE features using BTS Site Manager
FDD-LTE15A, Feature Descriptions and Instructions
2 Activating and deactivating LTE features using BTS Site Manager Purpose Follow this general BTS Site Manager (BTSSM) procedure to activate or deactivate LTE features. Before you start The eNB must already be commissioned. The BTS Site Manager can be connected to the eNB either locally, or from a remote location. For information on feature-specific prerequisites, see section Before you start of every feature-specific procedure.
Steps 1
Start the BTSSM application and establish the connection to the eNB. For details, see Launching BTS Site Manager in Commissioning Flexi Multiradio BTS LTE or the BTSSM online help (section Instructions).
2
Upload the configuration plan file from the eNB. When the BTSSM is connected to the eNB, it automatically uploads the current configuration plan file from the eNB. a) Select View ► Commissioning or click Commissioning on the View bar. b) The BTS Site checkbox, located in the Target section, is selected by default. This is the recommended setting. c) Choose the commissioning type. Use the Template, Manual, or Reconfiguration option depending on the actual state of the eNB. For details, see Manual commissioning, Performing template commissioning, and Performing reconfiguration commissioning in Commissioning Flexi Multiradio BTS LTE.
3
Modify the feature-specific eNB configuration settings. The feature-related settings are found in the set of Commissioning pages. In the top right-hand corner of the BTSSM window, there is a location bar that shows at which stage of the Commissioning process the user is. It is recommended that the user carefully reads the pages containing full eNB configuration information.

Activating and deactivating LTE features using BTS Site Manager
Send the commissioning plan file to the eNB. Sub-steps a) Go to the Send Parameters page. b) In section Send, choose whether the BTSSM should send to the eNB only the changed parameters: Only changes (may require reset), or a whole set of parameters: All parameters (requires reset). c) Click the Send Parameters button.
5
The new commissioning plan file is automatically activated in the eNB. Sub-steps a) After successful transmission of the parameters, the new configuration is automatically activated. The BTSSM automatically sends an activation command after finishing the file download.
b) If the configuration changes require restart, the eNB performs the restart now.

3 Descriptions of radio resource management and telecom features 3.1 LTE64: Service-based Handover Thresholds 3.1.1 Description of LTE64: Service-based Handover Thresholds Introduction to the feature The LTE64: Service-based Handover Thresholds feature introduces dedicated handover (HO) thresholds that are used when a UE has a QCI1 bearer active. Benefits End-user benefits Better radio frequency coverage for VoLTE users is ensured. VoLTE users can be handed over either earlier or later than data-only users. Operator benefits This feature provides: • •
different points of activation/deactivation of inter-frequency/inter-RAT measurements (A1/A2 event) different points of triggering of the inter-frequency/inter-RAT handover (A3/A5/B2 event)

For other dedicated HO thresholds, see the LTE2112: Dedicated Mobility Thresholds for SRVCC, LTE1198: RSRQ Triggered Mobility, and LTE738: SRVCC to 1xRTT/CDMA feature descriptions. The thresholds introduced with the LTE64: Service-based Handover Thresholds feature are as follows: • • • • •
dedicated VoLTE A2 threshold to start LTE inter-frequency measurements dedicated VoLTE A2 thresholds to start SRVCC to 1xRTT measurements dedicated VoLTE A1 threshold to stop inter-frequency or SRVCC measurements dedicated A3/A5 measurement setting per target frequency layer for inter-frequency HO dedicated B2 measurement (GSM, UTRAN) setting per target frequency layer
The A1/A2/A3/A5/B2 measurement configurations are updated with the establishment/removal of a QCI1 bearer. The usage of separate QCI1 thresholds is optional. This means that if the LTE64: Service-based Handover Thresholds feature is activated, and a value for a threshold for QCI1 is given, then this threshold will be used. If no such separate threshold is given, then a legacy threshold is used instead. The operator is free to use the separate QCI1 thresholds for each threshold which is supported. Upon the establishment of a QCI1 bearer, all thresholds are exchanged by the configured QCI1 values. The eNB always stores the last reported RSRP value of the UE and uses this at the QCI1 establishment/release to select (and configure) the correct

FDD-LTE15A, Feature Descriptions and Instructions
thresholds. This is done as thresholds may have to be changed and, therefore, another set of configured thresholds might be needed based on the last reported RSRP value (which is stored in the eNB). Disabling A2-based redirect for VoLTE calls The LTE64: Service-based Handover Thresholds feature introduces an O&M parameter to disable an A2-based redirect when a UE has a QCI1 bearer established. When this parameter is set to disabled, and the first QCI1 bearer is established for the UE, both RSRP- and RSRQ-based A2-redirect measurements (if configured) will be either deactivated or not activated. The measurements will be re-activated when the UE has no longer any QCI1 bearer. When this parameter is set to enabled, then the A2-based redirect configuration will not change in case of a QCI1 bearer establishment/release. Disabling the A2-based redirect when a UE has a QCI1 bearer is not controlled by the LTE64: Service-based Handover Thresholds feature flag. This feature flag controls the usage of dedicated thresholds only. System impact Interdependencies between features •

LTE2112: Dedicated Mobility Thresholds for SRVCC The actServBasedMobThr feature flag is shared by the LTE64: Service-based Handover Thresholds and LTE2112: Dedicated Mobility Thresholds for SRVCC features. LTE10: EPS Bearers for Conversational Voice This feature implements support for a QCI1 bearer and is required for the support of VoLTE calls. LTE55: Inter-frequency Handover The new A2/A3/A5 thresholds for an inter-frequency HO are used only if this feature is enabled. LTE56: Inter-RAT Handover to WCDMA SRVCC to WCDMA can be used only if this feature is enabled. LTE1060: TDD - FDD Handover This feature needs to be enabled together with the LTE64: Service-based Handover Thresholds feature if an FDD-TDD handover is needed for VoLTE calls. LTE1198: RSRQ Triggered Mobility When the A2-RSRQ mobility event is received, if the O&M flag for A2-redirect for QCI1 is disabled, and a UE has a QCI1 bearer, the A2-RSRQ-redirect measurement will not be activated. LTE423: RRC Connection Release with Redirect If the O&M flag for A2-redirect for QCI1 is disabled, and a UE has a QCI1 bearer, the A2-RSRP measurement for redirection will not be activated. LTE1407: RSRQ-based Redirect If the O&M flag for A2-redirect for QCI1 is disabled, and a UE has a QCI1 bearer, the A2-RSRQ measurement for redirection will not be activated.

Descriptions of radio resource management and telecom features
Impact on system performance and capacity The LTE64: Service-based Handover Thresholds feature improves SRVCC and VoLTE call drop rate by decreasing VoLTE coverage via earlier start of inter-frequency and interRAT measurements and specific HO thresholds for VoLTE leading to earlier handovers. This depends on how the HO thresholds are set. Management data Alarms There are no alarms related to this feature.

Functional overview The LTE738: SRVCC to 1xRTT/CDMA feature enables service continuity of voice services from the packet-switched (PS) to the circuit-switched (CS) domain when a UE with at least one voice service bearer (QCI1) changes from an LTE to a 1xRTT cell. The SRVCC capability of the UE and the MME is indicated by the MME with the S1AP: INITIAL CONTEXT SETUP REQUEST message. In case of a handover (HO), the target eNB is informed either by the MME via the S1AP: Handover Request message or by the source eNB via the X2AP: Handover Request message; see Figure 1: HO messages.

MME
SRVCC to 1xRTT/CDMA process The SRVCC is split into three areas: triggering, preparation, and execution. SRVCC trigger •
• •
If the UE has an EPS bearer with at least QCI1 established, and the MME and UE are SRVCC-capable, 1xSRVCC B2 is activated in a UE, based on the air conditions via mobility A2. Only one target 1xRTT carrier can be measured by one UE. QCI1 bearer: –
–
The eNB supports the SRVCC if there is at least one QCI1 bearer established. If the QCI1 bearer is established/released during ongoing measurement, the measurement targets are modified according to 1xSRVCC and HRPD HO measurements (if HO to eHRPD is enabled). The eNB supports 1xSRVCC in case of multiple QCI1 bearers. An evolved packet core (EPC) selects the bearer to execute the SRVCC.
SRVCC preparation •
•
If the eNB receives a measurement report from the UE, it initiates an inter-RAT HO by sending the RRC: Handover From EUTRA Preparation Request message to the UE. The eNB gets the RRC: ULHandoverPreparationTransfer message containing the 1xRTT origination message from the UE and sends the S1AP: UPLINK S1 CDMA2000 TUNNELING message with the CDMA2000 HO Required Indication to the MME.
SRVCC execution • •
The MME responds to the eNB with the S1AP: DOWNLINK S1 CDMA2000 TUNNELING message including the CDMA2000 HO Status information element (IE). The CDMA2000 HO Status IE indicates an HO preparation status as follows: –
Issue: 01D
a successful HO preparation: the eNB forwards the 1x Handoff direction message embedded in the RRC: MobilityFromEUTRACommand message to the UE; as a result, the UE is moved to the 1xRTT area

LTE426: System Time Broadcast for SIB8 The LTE738: SRVCC to 1xRTT/CDMA feature reuses the LTE426: System Time Broadcast for SIB8 feature. The eNB broadcasts the CDMA system time in SIB8 if the LTE738: SRVCC to 1xRTT/CDMA feature is enabled, and the time source is available. LTE10: EPS Bearers for Conversational Voice The LTE10: EPS Bearers for Conversational Voice feature is a pre-condition to establish a VoIP bearer. The LTE10: EPS Bearers for Conversational Voice feature must be activated to activate the LTE738: SRVCC to 1xRTT/CDMA feature. LTE7: Support of Multiple EPS Bearers The LTE7: Support of Multiple EPS Bearers feature is a pre-condition to establish a VoIP bearer. The LTE7: Support of Multiple EPS Bearers feature must be activated to activate the LTE738: SRVCC to 1xRTT/CDMA feature. LTE572: IMS Emergency Sessions To support an IMS emergency call over LTE, the LTE572: IMS Emergency Sessions feature needs to be enabled. 1xSRVCC for emergency calls is supported in case of an ongoing emergency bearer using QCI1. LTE490: Subscriber Profile-based Mobility, LTE486: PLMN ID Selected Mobility Profiles The LTE490: Subscriber Profile-based Mobility or LTE486: PLMN ID Selected Mobility Profiles feature might be active parallel to the LTE738: SRVCC to 1xRTT/CDMA feature. Mobility profiles shall not be supported in the LTE738: SRVCC to 1xRTT/CDMA feature. LTE1441: Enhanced CS Fallback to CDMA/1xRTT (e1xCSFB), LTE874: CSFB to CDMA/1xRTT for Dual RX UEs The LTE1441: Enhanced CS Fallback to CDMA/1xRTT (e1xCSFB), LTE874: CSFB to CDMA/1xRTT for Dual RX UEs and LTE738: SRVCC to 1xRTT/CDMA features can be activated independently. The LTE738: SRVCC to 1xRTT/CDMA feature serves the SRVCC-capable UE, while the LTE1441: Enhanced CS Fallback to CDMA/1xRTT (e1xCSFB)/LTE874: CSFB to CDMA/1xRTT for Dual RX UEs feature serves UEs without the SRVCC capability, but with the CSFB capability. LTE761: Advanced Target Cell Selection and Handover Retry for Intra-frequency Handover An HRL might be used to prohibit handover to cdma2000 systems, which needs to be considered by the LTE738: SRVCC to 1xRTT/CDMA feature. LTE116: Cell Bandwidth - 3 MHz, LTE117: Cell Bandwidth - 1.4 MHz When 1.4M/3MHz LTE cell bandwidth is used, the LTE738: SRVCC to 1xRTT/CDMA feature should be deactivated. The following features must be deactivated because only EUTRAN and CDMA target layers are supported for the LTE738: SRVCC to 1xRTT/CDMA feature: – – – –

3.3 LTE825: Uplink Outer Region Scheduling 3.3.1 Description of LTE825: Uplink Outer Region Scheduling Introduction to the feature The LTE825: Uplink Outer Region Scheduling feature increases the number of physical resource blocks (PRBs) available for data allocation in uplink (UL). For this purpose, this feature allows using the blanked outer region for the physical uplink shared channel (PUSCH). In addition, it enables the scheduling of the physical random access channel (PRACH) in the outer region. Benefits End-user benefits This feature does not affect the end-user experience. Operator benefits This feature provides: • • •
PRBs in one of the blanked physical uplink control channel (PUCCH) regions for PUSCH and PRACH more efficient exploitation of the available UL spectrum the RAN configuration flexibility and simplicity

Additional hardware requirements This feature requires no new or additional hardware. Functional description Functional overview The implementation of the LTE825: Uplink Outer Region Scheduling feature is inseparably connected with the LTE786: Flexible UL Bandwidth feature. The latter aims at reducing the UL bandwidth below the nominal system bandwidth. The bandwidth is reduced symmetrically on both edges of the UL spectrum by leaving the outmost PRBs unused. In order to improve the feature's functionality (for example, to reduce the UL bandwidth in an asymmetrical way or to enable an automatic SRS configuration), the LTE825: Uplink Outer Region Scheduling feature enhances its previous counterpart; therefore, it can be perceived as an addition to the already existing one. The LTE825: Uplink Outer Region Scheduling feature is supported by >3MHz system bandwidths. It enables the eNB to allocate the PUSCH and PRACH resources in one blanked PUCCH edge. The set of PUSCH PRBs in the blanked PUCCH edge is called an outer PUSCH region. The minimum recommended outer region's size is three PRBs. The PRACH can be placed in the outer PUSCH region when six or more consecutive PRBs are available. It ensures that the RAN configuration is more flexibile. In addition, this feature enables the eNB to utilize additional UL resources for the PUSCH scheduling (see Figure 2: The comparison of LTE786: Flexible UL Bandwidth and LTE825: UL Outer Region Scheduling features). This feature provides a method for setting up the PUSCH and PRACH in the blanked non-disturbed outer UL spectrum, and allows the allocation of unused PRBs for the outer region scheduling. An O&M parameter defines which one of the outer regions is permitted for PUSCH scheduling and which one of the two blanked PUCCH regions is added. Figure 2

Depending on the number of PRBs which are assigned to the inner PUSCH region, the eNB selects a proper sounding reference signal (SRS) configuration. The SRS configuration is selected out of a set of predefined SRS configurations. The selected SRS configuration is one with the largest SRS bandwidth that does not overlap the outer PUSCH region or the blanked PUCCH edges. Instead, it can overlap the used PUCCH PRBs. This method simplifies the RAN configuration. For the configuration of the outer scheduling region, the same RRM algorithms for power control (OLPC, CLPC, or IawPC), link adaptation (slowAMC, eULA, or fULA – fULA without the support of SRS in the outer region), and the same scheduling algorithms (CUS, IAS, or CAS – CAS without the support of SRS in the outer region) are applied. Automatic SRS configuration In the LTE825: UL Outer Region Scheduling feature, the sounding configuration is chosen automatically, depending on the number of PUSCH PRBs assigned to the inner scheduling region. The eNB selects the SRS configuration from a set of predefined configurations in such a way that the sounding in the blanked PUCCH, or rather in the outer PUSCH region, is prevented. It also covers the inner PUSCH region as much as possible. The coexistence of sounding resources and PUCCH is allowed. The automatic SRS configuration is done even if the LTE786: Flexible UL Bandwidth and LTE825: UL Outer Region Scheduling features are deactivated. System impact Interdependencies between features There are interdependencies between the following features: •

LTE786: Flexible UL Bandwidth The size of the blanked outer region which can be utilized for PUSCH and PRACH is defined by the LTE786: Flexible UL Bandwidth feature. The size of the configured outer PUSCH region is blankedPucch/2.

Impact on interfaces The LTE825: Uplink Outer Region Scheduling feature impacts the Uu interface in such a way that a second PUSCH region is additionally assigned to the already existing PUSCH region around the central frequency. Impact on network management tools This feature has no impact on network management tools. Impact on system performance and capacity This feature impacts system performance and capacity as follows: • •
g
The RAN-level system capacity increases in direct proportion to the number of PUSCH PRBs which are assigned to the UL outer region scheduling area. The average UL cell throughput increases (compared to the LTE786: Flexible UL Bandwidth feature used alone for the cell) by adding the PRBs in the outer PUSCH region. Note: For a 20-Mhz bandwith blanked with two regions of 5 Mhz, the average throughput and capacity approximate those of a 10-Mhz cell (this is without the LTE825: Uplink Outer Region Scheduling feature). With this feature, it is possible to gain one of the 5-Mhz blanked regions and, as a result, obtain a roughly 15-Mhz cell.

b) Set the PRACH frequency offset (prachFreqOff) parameter's value.
g
Note: PRACH has to be placed either in the outer PUSCH region or in the inner region at a place where the calculation rule is specified. The permitted range for PRACH frequency offset (prachFreqOff) is produced by a calculation formula: • •
from the lower limit: 0 to the upper limit: roundup (Blanked PUCCH resources (blankedPucch) / 2 - 6, and from the lower limit: roundup (LNCEL Maximum PUCCH resource size (MaxPucchResourceSize) + (blankedPucch) / 2) to the upper limit: LNCEL Uplink channel bandwith (ulChBw) (in PRBs) - 6 - roundup (MaxPucchResourceSize + blankedPucch) / 2)
The above parameters must be configured so that the lower limit is always below or equal to the upper limit of the permitted range. This is not enforced by the SW but needs to be followed during the configuration.
g
Note: LNCEL Maximum PUCCH resource size (MaxPucchResourceSize) is a calculated value that is computed by means of other O&M parameters. MaxPucchResourceSize is utilized to determine the correct offset allocation of the PRACH resources and to verify that the maximal allowed number of PUCCH resources per BW is not exceeded. MaxPucchResourceSize is produced by a calculation formula: •
MaxPucchResourceSize = nCqiRb + roundup {[((rounddown (((maxNrSymPdcch*12 - X)*dlChBw - roundup (phichRes*(dlChBw / 8))*12 16) / 36)) + n1PucchAn - pucchNAnCs*3 / deltaPucchShift) *deltaPucchShift] / (3*12)} + roundup (pucchNAnCs / 8) – blankedPucch, where: – –

from the lower limit: roundup (LNCEL: Maximum PUCCH resource size (MaxPucchResourceSize) + LNCEL: Blanked PUCCH resources (blankedPucch) / 2) to the upper limit: LNCEL: Uplink channel bandwith (ulChBw) in PRBs - 6 - roundup (MaxPucchResourceSize + blankedPucch) / 2, and from the lower limit: LNCEL: Uplink channel bandwith (ulChBw) in PRBs roundup (blankedPuccch/2) to the upper limit: ulChBw (in PRBs) - 6
The above parameters must be configured so that the lower limit is always below or equal to the upper limit of the permitted range. This is not enforced by the SW but needs to be followed during the configuration.
g
Note: LNCEL Maximum PUCCH resource size (MaxPucchResourceSize) is a calculated value that is computed by means of other O&M parameters. MaxPucchResourceSize is utilized to determine the correct offset allocation of the PRACH resources and to verify that the maximal allowed number of PUCCH resources per BW is not exceeded. MaxPucchResourceSize is produced by a calculation formula: •
MaxPucchResourceSize = nCqiRb + roundup {[((rounddown (((maxNrSymPdcch*12 – X)*dlChBw - roundup (phichRes*(dlChBw / 8))*12 16) / 36)) + n1PucchAn - pucchNAnCs*3 / deltaPucchShift) *deltaPucchShift] / (3*12)} + roundup (pucchNAnCs / 8) - blankedPucch, where: – –

X = 4, when maxNrSymPdcch = 1 or dlMimoMode set to SingleTX, TXDiv, Dynamic Open Loop MIMO or Closed Loop Mimo X = 8, when maxNrSymPdcch > 1 and dlMimoMode set to 4-way TXDiv or Closed Loop MIMO (4x2)
Send the parameters to the eNB according to the procedure described in section Activating and deactivating LTE features using BTS Site Manager.
Expected outcome The LTE825: Uplink Outer Region Scheduling feature is activated; PUSCH and PRACH scheduling in the outer scheduling area is possible.

Procedure 1
Follow the general procedure described in section Activating and deactivating LTE features using BTS Site Manager. In Step 3 (Modify the feature-specific eNB configuration settings) of the general procedure perform the steps described in this procedure.
2
Deactivate the Target UL outer scheduling region (selectOuterPuschRegion) parameter. a) b) c) d)
Go to the Radio Network Configuration page. Expand the MRBTS object. Select the LNCEL object. Set the Target UL outer scheduling region (selectOuterPuschRegion) parameter's value to none.
With the deactivation of the LTE825: Uplink Outer Region Scheduling feature, the outer PUSCH region no longer exists; PRACH is then set up in an inner PUSCH region. In that case PRACH frequency offset (prachFreqOff) parameter needs to be reconfigured accordingly.
g
Note: If selectOuterPuschRegion is configured to None or blankedPucch is less than 12, then the permitted range for prachFreqOff is produced by a calculation formula: •
from the lower limit: roundup LNCEL: Maximum PUCCH resource size (MaxPucchResourceSize)+LNCEL: Blanked PUCCH resources (blankedPucch) / 2) to the upper limit: LNCEL: Uplink channel bandwith (ulChBw) (in PRBs) - 6 - roundup LNCEL: Maximum PUCCH resource size (MaxPucchResourceSize) + LNCEL: Blanked PUCCH resources (blankedPucch) / 2)
The above parameters must be configured so that the lower limit is always below or equal to the upper limit of the permitted range. This is not enforced by the SW but needs to be followed during the configuration.
Expected outcome The LTE825: Uplink Outer Region Scheduling feature is deactivated.

Note: For Timing advance (TA) type1, a UE should support the UE Rx-Tx time difference measurement capability. Additional hardware requirements Providing the operator's network contains a mobility management entity (MME) and ESMLC provided by other vendors, it is assumed that these network elements support the LPPa messaging for E-CID before the LTE951: Enhanced Cell ID Location Service feature is deployed. It is also assumed that any timers on the MME and E-SMLC (that are preventing message response timeouts) can be adjusted as they are needed to ensure successful inter-operability with Nokiaan eNB. Functional description Functional overview The LTE951: Enhanced Cell ID Location Service feature introduces enhanced cell ID (ECID) location services. The location service is performed in two steps: 1. The UE is positioned based on its serving cell's ID. 2. The UE is positioned more accurately inside a single cell, using one of the following four methods: • • •

Issue: 01D
FDD-LTE15A, Feature Descriptions and Instructions
Descriptions of radio resource management and telecom features
In a location measurement procedure, information about the position of a UE is transmitted from an eNodeB to E-SMLC in the LTE Positioning Protocol A (LPPa) LPPA: E-CID MEASUREMENT INITIATION RESPONSE message, which is encapsulated within the S1AP: UPLINK UE ASSOCIATED LPPA TRANSPORT message. Only on-demand measurements are supported by an eNB. The eNB can perform multiple measurements simultaneously. Providing a measurement request is received by an eNB while performing a handover of a UE, the failure response is sent back to the E-SMLC. When employing the LTE951: Enhanced Cell ID Location Service feature in cells with spatially separated antennas (for example a super cell), the measurements provided by LTE951: Enhanced Cell ID Location Service cannot be referenced to a single antenna as they do not have a well-defined reference point. Whether to use the LTE951: Enhanced Cell ID Location Service feature with separated antennas and an unclear reference point is left for the operator to decide. When deploying the feature, there are two scenarios for an operator to consider: •
•
not to configure an E-UTRAN access point information in the eNodeB. The eNodeB will then not report the E-UTRAN access point information to the E-SMLC, and it is assumed that the E-SMLC will cope with this (the E-UTRAN access point information element (IE) is optional in the E-CID measurement result). define the E-UTRAN access point position as a geographical mean value of the antenna positions (logical antenna position). Use the uncertaintyAltitude, uncertaintySemiMajor, and uncertaintySemiMinor attributes of the eutranAccessPointPosition configuration parameter to express the geographical inaccuracy of this logical antenna position.
Measurement types Timing advance type 2 (TA type 2) This measurement is performed by an eNB and describes the time difference between the reception of an uplink radio frame #i containing PRACH and the transmision a of downlink radio frame #i. For details, see 3GPP TS36.214. The reference point used by an eNB to perform the measurements is the antenna connector. Timing advance type 1 (TA type 1) This approach measures the following two timing differences: •
•
the time difference between the reception of a downlink radio frame #i and the transmission of a corresponding uplink radio frame #i, measured by the UE (UE RxTx time difference) the time difference between the reception of an uplink radio frame #i and the transmission of a downlink radio frame #i at the eNB (eNB Rx-Tx time difference)
The measurement is conducted only after an E-SMLC request. After receiving such a request, an eNB instructs a UE to perform the UE Rx-Tx measurements. After receiving a UE Rx-Tx measurement from the UE, the eNB computes the Timing advance type 1 and sends it to the E-SMLC. Before performing the Timing advance type 1 procedure, the E-SMLC verifies the UE's capability to perform measurements via an LPP protocol.

FDD-LTE15A, Feature Descriptions and Instructions
The reference point used by an eNB to perform the measurements is the antenna connector. Intra-frequency Reference Signal Received Power (RSRP) and/or Reference Signal Received Quality (RSRQ) These measurements are performed by a UE and reported to an eNB. When a request for the RSRP, or RSRQ, or both of them arrives at an eNB, the eNB initiates an intrafrequency measurement configuration at the UE with a reportStrongestCells purpose. The exact type of this measurement is set by the value of triggerQuantity. Subject to a desired measurement, its value is set either to RSRP (in case the RSRP or both measurements are requested), or RSRQ (in case only this measurement is needed). The UE sends a measurement report to the eNodeB, which in turn sends the RSRP and/or RSRQ measurements to the E-SMLC, which calculates the UE's position. System impact Interdependencies between features The following features are interrelated with the LTE951: Enhanced Cell ID Location Service feature: •
•
• •
•
LTE433: Cell Trace The feature enables operators to simultaneously trace all UEs that are in an RRC_CONNECTED state in a target cell. LTE644: Configurable Cell Trace Content The feature allows operators to select a message type, based on which the UEs that are in an RRC_CONNECTED state are filtered and traced in a target cell. LTE163: Subscriber and Equipment Trace The feature enables operators to trace a specific IMSI or IMEI. LTE782: ANR Fully UE-based Providing the LTE782: ANR Fully UE-based and LTE951: Enhanced Cell ID Location Service features are enabled, the location service measurement request takes higher priority than an ANR measurement. LTE1501: Measurement Report (MR) Addition to Cell Trace If the LTE1501: Measurement Report (MR) Addition to Cell Trace and LTE951: Enhanced Cell ID Location Service features are enabled, the location service measurement request takes higher priority over the measurement requested by the LTE1501: Measurement Report (MR) Addition to Cell Trace feature.
Impact on interfaces The LTE951: Enhanced Cell ID Location Service feature adds support to the E-CID measurement initiation procedure. This procedure utilizes the UL/DL LPPa messages to convey the E-CID measurement messages between an eNB and E-SMLC. This feature impacts the following interfaces: •

All the parameters can be found in Management data. Certain parameters have to be set consistently between eNBs and BM-SC. Please refer to the sections below. MBMS subframe percentage determination When determining the percentage of downlink subframes that need to be allocated to MBMS, the operator needs to consider the following items: data rates of MBMS services that will be transmitted simultaneously MCS at which the MBMS data will be transmitted (Data MCS) system bandwidth (10, 15, or 20 MHz)
• • •
The Table 33: MBMS Data Rate table, derived from TS36.213 section 7.1.7.2.1, provides guidance for making subframe percentage selections based on the above items. Nokia recommends subframe percentage selection not to exceed 40% to ensure that unicast capacity is not adversly affected. Table 33

* Bits/Second is reduced by 10% due to MBMS signaling subframes and RLC/MAC header overhead. MBMS Subframe Percentage Examples Example 1: Single service • • •
video stream with 720p @ 2 Mbps cell BW = 15 MHz data MCS selected = 10
Based on the video specifications, and using the MBMS Data Rate table, 30% MBMS subframes is the lowest MBMS subframe percentage that provides at least 2 Mbps (2,365,200 bps) with the given parameters. Example 2: Multiple services with multiple data MCSs Video stream with 720p @ 2 Mbps • •
cell BW = 10 MHz data MCS selected = 10
Audio Streaming @ 100 kbps • •
cell BW = 10 MHz data MCS selected = 15
The video stream will require at least 30% MBMS sub frames to achieve 2 Mbps (2,365,200 bps) ) at 10 MHz and MCS = 10. The audio streams will require an additional 100 Kbps at 10MHz and MCS = 15. Since the 30% of MBMS sub frames selected provides 2,365,200 Kbps, the remaining bandwidth is more than is necessary for the audio, this excess bandwidth is more than enough to support the 100 Kbps required by the audio streams. No additional MBMS sub frames need to be allocated for the audio. Configuration for MBMS data flow synchronization In order to ensure synchronized radio interface, MBMS transmission from the cells controlled by different eNBs, MBMS SYNC-protocol [TS 25.446] support is needed between BM-SC and the eNBs. As part of the SYNC-protocol, certain parameters have to be set consistently between the BM-SC and the eNBs, namely:

Descriptions of radio resource management and telecom features
Common time reference: on the eNB, this parameter is called MBMS SYNC Reference. This parameter has to be set in the same way on both the eNB and BMSC after ensuring that both the eNB and BM-SC are synchronized to the same clock source such as NTP or GPS synchronization. Example: Based on NTP on the eNB, if MBMS SYNC Reference::Integral Seconds is set to 3615771600, and MBMS SYNC Reference::Fractional Seconds is set to 0, then the same equivalent value has to be provisioned on the BM-SC. Synchronization Period: as part of the SYNC-protocol, both BM-SC and eNB for each service have to maintain the same synchronization period. On the eNB, this parameter is called MBMS SYNC Period, after which the relative timestamps within the SYNC PDUs can wrap around. Synchronization sequence: Each SYNC PDU contains a timestamp that indicates the start time of a sequence for an MBMS service. Since the BM-SC is not aware of the MCE/eNB scheduling boundaries, the synchronization sequence length that is configured on the BM-SC has to be proportional to the Multicast Channel Scheduling Period (MSP) on the eNB. The MSP length provisioned in the eNB is one or multiple times of the synchronization sequence length for MBMS services in the MCH.
The BM-SC includes a timestamp in the SYNC PDUs, based on which the eNB has to send MBMS data over the air interface. The time stamping of SYNC PDUs, is based upon a relative time value from the above common time reference, which refers to the start time of the synchronization period. The eNB will schedule the received data packets in the first MSP following the time point indicated by the timestamp. If they are not configured properly, a poor MBMS service may be observed due to excessive packet drops. Too long of an MSP with a high dataMCS will require that large amounts of data are buffered at the eNB prior to the MBMS transmission. If the buffered data size becomes too large, packets may become lost. The Activate support for MBMS (actMBMS) parameter can only be set to true only if all the following conditions are fulfilled: • • • • • •
The eNB has the RNW database activated and is in service. NetAct is in service and the DCN connection to eNB is established via OMS. At least one S1 link is established. MBMS-related information in the transport domain is configured. At least one LNCEL instance with earfcn equal to MBSFN-mbsfnEarfcn and chBw equal to MBSFN-mbsfnDlChBw must be created. The following conditions must be fulfilled in all cells which are candidates for MBMS broadcasting, that is with earfcn equal to MBSFN-mbsfnEarfcn and chBw equal to MBSFN-mbsfnDlChBw: –

Additional hardware requirements There are no additional hardware requirements to this feature. Functional description Functional overview The RAN information management (RIM) procedures support the core network in an information exchange between peer application entities located in GERAN, UTRAN, or the E-UTRAN access network. The LTE1196: RAN Information Management to WCDMA feature allows up-to-date system information (SI) of WCDMA neighbor cells to be transferred from a remote radio network controller (RNC) to a local eNB. This proccess is used to populate WCDMA SI for redirection to the WCDMA procedure.

The RIM function enables the eNB to retrieve SI from a target WCDMA cell. The retrieved information is used to automatically fill and update the related SI attributes for all the enabled features to which an RRC connection release with a redirect to WCDMA is applied. This proccess is presented in Figure 6: Redirection procedure with SI. Figure 6

For each neighbor WCDMA frequency of an LTE cell, up to 16 WCDMA neighbor cells can be enabled to provide SI via RIM in the redirect message. The same SI is sent in case of: • • •
a normal RRC connection release with a redirect to WCDMA a normal redirect based on CS fallback to WCDMA an emergency CS fallback to WCDMA to the UE
The assigned mobility profile and the UE capabilities are considered when selecting the SI to be added to the redirect message.
g
Note: In extreme conditions, the RIM UTRA SI application (ENBC) is running on FSMr2 board, and the memory for RIM UTRAN SI storage may be used up. For the new coming up LTE cells, the UTRAN SI for some WCDMA neighbor cells might be temporarily unavailable (not in UEC) until the next UTRAN SI update or RIM association re-establishment. If the WCDMA neighbor cells’ RIM interface status (rimStatus) is set to available at eNB level, it does not have impact on this process. It is caused due to memory capacity limitation of FSMr2 board. RAN information procedure for the enabled WCDMA neighbor cell The RIM protocol is encapsulated in the S1AP.MME DIRECT INFORMATION TRANSFER and the S1AP:ENB DIRECT INFORMATION TRANSFER messages. The following RIM procedures are supported: • • • • •

Redirection procedure Selecting suitable cells The following conditions must be fulfilled for the eNB to check the RIM interface status (rimStatus) parameter for each suitable WCDMA cell: • •
if rimStatus is available, SI for the WCDMA cell is taken from RIM. if rimStatus is unavailable or disable, SI for the WCDMA cell is not included (theWCDMA cell is omitted by the eNB).
The following conditions must be fulfilled to check all objects (LNRELW object instances) related to the WCDMA neighboring cell for the LTE cell: • •
the WCDMA cell's frequency is the same as the chosen target frequency represented by the UARFCN value an active flag allows adding SI in a release message
Elimination of unsuitable cells by CS fallback If the RegisteredLAI was received, the eNB is checking PLMN and LAC values. At least one of the primary/secondary PLMNs and LAC configured for the WCDMA cell (in LNADJW), which SI is checked for, must be included in RegisteredLAI IE. Otherwise, SI for that WCDMA cell is eliminated from the list. • •
If the list is not empty, elimination of unsuitable targets is stopped. If the list is empty, eNB checks again all the targets from the original list as it was before, but only the PLMN value will be checked. Primary/secondary PLMNs configured for the WCDMA cell (in LNADJW) must be included in RegisteredLAI IE. Otherwise, SI for that WCDMA cell is eliminated from the list.
If the RegisteredLAI was not received, the handover restriction list was received and there was no emergency call, at least one of the primary/secondary PLMNs configured for the WCDMA cell (in LNADJW) must be included in the set of PLMN IDs allowed by the UE (a combination of Serving PLMN ID and Equivalent PLMN IDs optionally provided within the handover restriction list). Otherwise, SI for this WCDMA cell is eliminated from the list.
g
Note: For a selected UTRAN frequency, the O&M is configured for a UE context release only; the eNB will not add the WCDMA SI to the CSFB redirection message. Elimination of unsuitable cells by the UE context with redirection The list of chosen SI is checked in search of any unsuitable targets that need to be deleted. If the handover restriction list was received, and there was no emergency call, at least one of the primary/secondary PLMNs configured for the WCDMA cell (in LNADJW) must be included in the set of PLMN IDs allowed by the UE (a combination of serving PLMN ID and equivalent PLMN IDs optionally provided within the handover restriction list). Otherwise, SI for this WCDMA cell is eliminated from the list.

Additional hardware requirements This feature requires no new or additional hardware. Functional description Functional overview The LTE1321: eRAB Modification – GBR feature introduces functionalities on top of the LTE519: eRAB Modification feature. Before the implementation of the LTE1321: eRAB Modification – GBR feature, the LTE519: eRAB Modification feature allowed, among others, an ARP parameter modification (in the GBR bearer). The LTE1321: eRAB Modification – GBR feature additionally allows the guaranteed bit rate (GBR)-related and maximum bit rate (MBR)-related QoS parameters modification (for the GBR bearers) to facilitate the requirements made by the MME or UE, as presented in Table 40: LTE519 and LTE1321 comparison.

In this case, the P-GW sends an UPDATE BEARER REQUEST message to an MME, which initiates the procedure. The MME sends the S1AP: E-RAB MODIFY REQUEST message to the eNB. The eNB analyzes the modification request and decides whether the modification can be handled or not (a standard admission control procedure as if an additional GBR bearer was being established). If any of the parameters for the modification cannot be changed, the whole procedure is rejected. Providing the modification can be performed, the eNB sends an RRC: RRC Connection Reconfiguration message to a UE. Later on confirmations are sent to the eNB, MME and P-GW/HSS. For more details on signaling, see Figure 7: Complete signaling flow. In case the increase in the GBR is not possible, the previous bit rate is configured along with a failure message being sent to the MME. The eRAB modification procedure might involve more than one bearer simultaneously. HSS-triggered eRAB modification This procedure is initiated when the user expends the whole pool of guaranteed resources for data transmission. After exceeding the operator-defined threshold (for example 1 GB), the HSS sends the INSERT SUBSCRIBER DATA message to the MME, which proceeds with the bit rate cut procedure. The MME sends the S1AP: E-RAB MODIFY REQUEST message to an eNB; the remainder of the procedure is the same as in the scenario for P-GW-triggered eRAB modification described above. The end user will now have a treshold value of 1 Mbps, compared to the previous threshold value of 100 Mbps (as a result of exceeding 1 GB transfer). For a more detailed presentation of signaling between the MME and UE, see: Figure 7: Complete signaling flow. Figure 7

3.8 LTE1357: LTE-UTRAN Load Balancing 3.8.1 Description of LTE1357: LTE-UTRAN Load Balancing Introduction to the feature The LTE1357: LTE-UTRAN Load Balancing feature enables load balancing from LTE to WCDMA. Benefits End-user benefits In case of a highly loaded LTE network, optimized service for the end user is provided. Operator benefits The LTE1357: LTE-UTRAN Load Balancing feature reduces the probability of overload situations in the LTE network due to offloading sufficient UEs to the WCDMA network.

Additional hardware requirements This feature requires no new or additional hardware. Functional description With the LTE1357: LTE-UTRAN Load Balancing feature, the eNB monitors the load in its own cells. If a cell load is high, the eNB initiates a load-based handover (HO) from an LTE to a WCDMA cell, as shown in Figure 8: LTE - UTRAN load balancing.

Load supervision If the LTE1357: LTE-UTRAN Load Balancing feature is activated (the actUtranLoadBal paramater value is set to true), each cell constantly measures and calculates the load for GBR, non-GBR, and PDCCH load types. The operator can configure new load thresholds for these load types. If at least one of the high load threshold is exceeded, the load balancing function becomes active.
g
Note: Generally, load balancing with inter-RAT targets is started if one of the loadtypes: loadtype1, loadtype2, or loadtype3 is bigger than the relevant typehighthreshold (type1highthreshold, type2highthreshold, or type3highthreshold). Load balancing with inter-RAT targets is stopped if all of the loadtypes: loadtype1, loadtype2, and loadtype3 are smaller than the relevant typetargetthreshold (type1targetthreshold, type2targetthreshold, and type3targetthreshold). If the load of all load types in the source LTE cell is reduced below the target threshold, all load balancing is stopped in that cell. Load balacing is in an inactive state, and the load monitoring is ongoing. Load balancing candidates The UE, to be handed over from an LTE to a WCDMA cell, must be a load balancing candidate (UE entering the cell, UE in an RRC connected state (every time when the periodic retry timer of the UE expires), or UE coming in with an HO) and meet the following conditions: • • • • • •
The UE has UTRAN UE capabilities (feature group index bit 15 and 114 optionally). The UE has data bearers only (no QCI1 bearer). An emergency bearer is not active. The UE is not configured for carrier aggregation. The UE has the B1 measurement objects configured. The UE reports sufficient coverage with WCDMA.
The load balancing candidate measures the radio conditions of the WCDMA target cells using the B1 measurement. LTE-WCDMA handover

If the S1 handover is triggered for inter-RAT load balancing, the source eNB sets the Cause IE value to Reduce load in serving cell. As long as load balancing handovers are accepted, the WCDMA cell is a target cell for load balancing. If the WCDMA target cell rejects load balancing handovers (cause: No Radio Resources Available in Target Cell or load reject reasons), the target cell is temporarily blacklisted for load balancing. In this case, no further load is shifted to that cell. The eNB allocates a load-balancing handover target list to WCDMA. This target cell list is taken from the newly-defined white list for load balancing. System impact Interdependencies between features •

LTE56: Inter-RAT Handover to UTRAN The LTE56: Inter-RAT Handover to UTRAN feature must be activated together with the activation of load balancing. LTE1073: Measurement-based Redirect to UTRAN The LTE1073: Measurement-based Redirect to UTRAN feature must not be configured to apply redirect to all UEs if the LTE1357: LTE-UTRAN Load Balancing feature is activated. LTE736: CS Fallback to UTRAN The CS fallback reduces load independently of the LTE1357: LTE-UTRAN Load Balancing feature. If one of the following features is activated along with the LTE1357: LTE-UTRAN Load Balancing feature, a round robin offloading might be done (either B1 or A4 is configured for a candidate UE). – – – –

FDD-LTE15A, Feature Descriptions and Instructions
A UE which is sent to UTRAN by a measurement-based redirect, instead of a PS HO, is not used for inter-RAT load balancing. If the LTE1357: LTE-UTRAN Load Balancing feature is activated, the LTE2162: SRVCC for Network Deployments Not Supporting PS HO feature does not have to be configured to send all UEs without QCI1 to UTRAN by redirect. LTE497: Smart Admission Control There are dependencies between the load balancing thresholds and the maxGbrTrafficLimit smart AC threshold. The thresholds should be configured that the load balancing starts first before the congestion handling is started. LTE1103: Load-based Power Saving for Multi-layer Networks Load balancing and energy saving functions might work in opposite direction, depending on traffic distribution. The recommendation is that the LTE1103: Loadbased Power Saving for Multi-layer Networks and LTE1357: LTE-UTRAN Load Balancing features are not used at the same time.
Impact on interfaces This feature has no impact on interfaces. Impact on network management tools This feature has no impact on network management tools.

The 1xRTT AC barring information is broadcast as part of system information block 8 (SIB8) to the UEs. Parameters for 1xRTT AC barring are operator-configurable. The eNB supports adapting SIB8 1xRTT AC barring broadcast on the air interface, based on the combination of: • •
the SIB8 1xRTT AC barring O&M configuration value the SIB2:ac-BarringInfo IE value
The algorithm of ac-Barring0To9-r9 IE adaption, based on SIB2 AC barring information, is not applied if acBarring0To9Adapt = false. The acBarring0To9-r9 IE of SIB8 should be set as RttAcbDb. Otherwise, the algorithm of ac-Barring0To9-r9 IE adaption, based on SIB2 AC barring information, is applied. The RttAcbDb factor is a source one, expected by the operator of the CDMA AC barring pass rate in CDMA 1xRTT native network. In case of static 1xAC barring, the RttAcbDb = CDFIM:rttAcBar:acBarring0To9 or in case of automatic 1xAC barring, CDFIM:rttAcBarOvl:acBarring0To9. The 1xACB adaption is applicable for both static AC barring and automatic AC barring for overload.
g
Note: RttAcbDb = 0 means that the operator expects the CDMA AC barring pass rate equal 100% for the CDMA access overload class 0-9 native 1xRTT network. There is no need to enforce any extra LTE SIB8 AC barring.
RttAcbDb = 63 means that the operator expects the CDMA AC barring pass rate equal 0% for the CDMA access overload class 0-9 native 1xRTT network. Because SIB8 1xRTT AC barring will only apply to UE's that have successfully accessed the LTE network, and SIB2 LTE AC barring may prevent some accessing, this can result in a higher overall 1xRTT barring than the customer might desire. The purpose of Adaption is to adjust the barring factors in SIB8 slightly based on how much SIB2 barring is in effect, to give the customer the same overall 1xRTT AC barring they would see on the native 1xRTT system with the same 1xRTT database settings. In the LTE1635: SIB 8 AC Barring for 1xRTT feature, when a UE is in R8/R9 1xCSFB mode access 1xRTT network via LTE access the LTE1441: Enhanced CS Fallback to CDMA/1xRTT (e1xCSFB) feature, during 1xCSFB, 1xSMS, 1xRegistration and others, will follow both SIB8 AC barring and SIB2 AC barring. System impact Interdependencies between features Activation of the LTE1635: SIB 8 AC Barring for 1xRTT feature is meaningful only when the LTE1441: Enhanced CS Fallback to CDMA/1xRTT (e1xCSFB) feature is activated, and SIB8 CSFB-RegistrationParam1xRTT IE is broadcast. When a UE is in R8/R9 e1xCSFB mode, access the 1xRTT network via the LTE network; the SIB8 AC barring is following together with SIB2 AC barring. The LTE1635: SIB 8 AC Barring for 1xRTT feature is not supported by the following features: •

The objective of this feature is to increase a UE's battery savings. Benefits End-user benefits This feature increases a UE's battery savings achieved by using DRX during the time when a measurement gap is installed.

Additional hardware requirements This feature requires no new or additional hardware. Functional description Functional overview The LTE1679: DRX with Parallel UE Measurement Gaps feature is an extension of the LTE42: Support of DRX in RRC Connected Mode feature that introduced the support of DRX in a CONNECTED mode. It brought an eNB's support for discontinuous monitoring of the DL control channel (PDCCH) by the UE (DRX). This solution employed a periodic active/sleep pattern, thus creating phases where the UE is not able to receive or transmit data instantaneously. For more information about the support of DRX in an RRC connected mode, see LTE42: Support of DRX in RRC Connected Mode. The solutions in both of the features allow increasing a UE's battery lifetime. Maximum power savings are expected for a very bursty kind of traffic patterns (short phases with data followed by long phases with no data at all) and very long inactivity time, however, at the expense of increasing the DL latency (at the start of a downlink data transmission).

Note: The LTE1679: DRX with Parallel UE Measurement Gaps feature can be enabled only if the LTE42: Support of DRX in RRC Connected Mode feature is enabled. The description of this feature comprises the following: • • • •
Measurement gaps in DRX mode Measurement gap installation Alignment of measurement gaps DRX/measurement gaps activation rules
Measurement gaps in DRX mode The LTE1679: DRX with Parallel UE Measurement Gaps feature allows the UE to use the DRX in parallel with measurement gaps. However, the following constraints are brought: •
• •
g
The only supported DRX profiles during measurement gaps are the drxProfile2, drxSmartProfile2, or drxProfile1. No other DRX profile is supported during measurement gaps. With the activation of the UE measurement gaps, the drxProfile2 or drxSmartProfile2 are considered regardless whether a bearer with QCI 1 has been established or not. If there is a bearer mapping to drxProfile1 and the drxProfile1 has a higher priority than drxProfile2/drxSmartProfile2, then the drxProfile1 is activated. The "normal DRX profile selection" is applied again when the UE measurements are deactivated. Only the 40ms-measurement gaps are supported. The DRX has to be turned off during the circuit-switched fallback (CSFB) to minimize the delay on the RRC interface. Therefore, CSFB-triggered measurement gaps are excluded and, upon installing the CSFB measurement gap, DRX is turned off via RRC messaging to the UE. Note: In this feature description, the term "measurement gap" refers to non-CSFB measurement gaps.
Measurement gap installation Upon installing a measurement gap, when the LTE1679: DRX with Parallel UE Measurement Gaps feature is enabled, the drxProfile2, drxSmartProfile2, or drxProfile1 is used for a UE. The measurement gap offset calculation algorithm, introduced by this feature, is used to switch the DRX profile when the measurement gap is installed and to calculate the new DRX offset. The measurement gap offset is selected in such a way that the DL scheduling gap caused by the measurement gap does not overlap with the DRX On duration time. In some cases, it is impossible to meet such a criterion, and then the overlap is minimized. The measurement gap offset calculation algorithm is used even if the DRX is not utilized during the measurement gap time, or even if the LTE1679: DRX with Parallel UE Measurement Gaps feature is disabled. The installation of the measurement gap as well as the DRX profile change (if applicable) are communicated to the UE via RRC. Upon uninstalling the measurement gaps at a UE, the eNB shall re-select the DRX profile as "normal," which means without enforcing the drxProfile2/drxSmartProfile2 in the DRX selection algorithm. Alignment of measurement gaps

Descriptions of radio resource management and telecom features
It is required to align the measurement gaps with the potential occasions of the scheduling requests so that not all of those occasions are blanked continously. Consequently, an alignment is required whenever the periodicity is the same or different for a scheduling request and measurement gap. DRX/measurement gaps activation rules When the DRX and measurement gaps compete, and the LTE1679: DRX with Parallel UE Measurement Gaps feature is activated, the eNB proceeds as follows: •
•
If the measurement gaps are already enabled and the DRX profile needs to be set up at the UE, the eNB releases the measurement gaps and sets the DRX profile if and only if the DRX is required for resolving the cell identity of a target cell for a handover, or the measurements which are currently using the gaps are not eventbased. Otherwise, measurement gaps are always kept. When the conditions for keeping the measurement gaps or the DRX profile end, the eNB evaluates whether to set up another DRX profile or measurement gaps, depending on the actual RRC connection status.
System impact Interdependencies between features The following feature has to be enabled before the activation of the LTE1679: DRX with Parallel UE Measurement Gaps feature: •

The following features do not cooperate with the LTE1679: DRX with Parallel UE Measurement Gaps feature: • •
LTE736: CS Fallback to UTRAN LTE1441: Enhanced CS Fallback to CDMA/1xRTT (e1xCSFB)
The LTE1679: DRX with Parallel UE Measurement Gaps feature allows the DRX to be considered during non-CSFB measurement gaps. During CSFB measurement gaps, the DRX has to be disabled. The following features cooperate with the LTE1679: DRX with Parallel UE Measurement Gaps feature: • • •
LTE56: Inter RAT Handover to WCDMA LTE55: Inter-frequency Handover LTE442: Network Assisted Cell Change to GSM
The features utilize the measurement gaps. Previously, the DRX had to be disabled when a measurement gap was installed. The LTE1679: DRX with Parallel UE Measurement Gaps feature removes this restriction so that the DRX can potentially stay enabled during the time when a measurement gap is installed in the UE.

Additional hardware requirements This feature does not require any new or additional hardware. Functional description Functional overview The LTE1788: Automatic Access Class Barring feature is an enhancement of the LTE1047: Control Plane Overload Handling feature. The LTE1788: Automatic Access Class Barring feature brings an additional value to the OVL2 state of the LTE1047: Control Plane Overload Handling feature. The feature performs the AC barring for the control-plane signaling when an eNB remains in the OVL2 state for an operatorconfigurable time. Automatic AC barring is also applied to 1xRTT, which is contained in SIB8. AC barring is applicable to the following services: • • • • • •
mobile-originating data mobile-originated signaling Service Specific Access Control (SSAC) for voice SSAC for video circuit-switched fallback (CSFB) to UTRA/GSM 1xCSFB to CDMA
Operational description The feature is triggered when an eNB remains in OVL2 for an operator-configurable time period. The time period is set by the Automatic AC Barring start timer (autoAcBarringStartTimer) parameter. The timer is started immediately after the cell enters the OVL2 state. When triggered, the feature starts an automatic AC barring for SIB2 and (if configured) SIB8. This means that all signaling that meets the configured criteria will not be admitted. At the same time, when the feature is triggered, the TIME_AC_BAR_OVL (Aggregated time period of automatic class class barring due to overload) counter is run. When the eNB goes back to the OVL0 state, the Automatic AC Barring stop timer (autoACBarringStopTimer) timer is started. If the base station does not go back to the OVL2 state within that time frame, the automatic AC barring functionality as well as the TIME_AC_BAR_OVL (Aggregated time period of automatic access class barring

due to overload) counter are turned off. After that, the static access class barring is applied, if configured. In case there is no static AC barring configured, no AC barring is applied in the eNB. After leaving the OVL2 state when the static AC barring is activated, the parameters (mandatory in the case of automatic AC barring) configured for the automatic AC barring (for example AC barring for signaling OVL (acBarSigOvl), AC barring for originating calls OVL (acBarOcOvl), or AC Barring for CDMA2000 1xRTT OVL (rttAcBarOvl)) are ignored. The frequent switch between automatic AC barring applied and not applied along with the C-plane overload level change might trigger a frequent SIB2/SIB8 AC barring-related system information change. This might cause a systemInfoValueTag overflow (the systemInfoValueTag changes more than 31 times within three hours). To avoid the overflow solely due to the LTE1788: Automatic Access Class Barring feature, a CCPMconsistency checking rule is applied. This means that the feature can be triggered only when the previous activation time was at least (or exactly) 15 minutes before the next activation time (the sum of autoAcBarringStartTimer and autoACBarringStopTimer must be greater than or equal to 15 minutes). Possible user scenarios The benefits of LTE1788: Automatic Access Class Barring are mostly noticeable in times of a high traffic load, for example, New Year's Eve or in overcrowded spaces such as stadiums, etc. •
•
g
New Year's Eve The eNB's load is increasing in a few hours (2–3 hours). There are no sudden load peaks taking place, but the number of connections is increasing continuously. The traffic mix might include a circuit-switch fallback (CSFB voice), SMS, regular LTE data/signaling, etc., but the subscriber's mobility is kept unchanged. All cells are supporting more traffic than the engineered capacity, which results in at overload at an eNB level. Train arriving at a station Note: In this case, the operator must pay attention to the systemInfoValueTag changes. The maximum value of 31 changes in three hours might be easily exceeded due to a too low value of the autoAcBarringStartTimer and autoACBarringStopTimer.
•
When a train arrives at a station or leaves a long tunnel, a large number of unexpected signaling cases emerge (tracking area updates, RRC connection requests, etc.). Such a large nominal number of signaling cases exceed the engineered eNB's capacity and eventually leads to an overload state, which subsequently leads to triggering the automatic AC barring procedure. In these scenarios, in order to achieve a quick response from the eNB to the increasing overload, a very small Tstart_acb guard timer value is expected to be configured by the operator. Disaster area When a natural disaster takes place in a certain geographical area, an overload state on an eNB serving that area is expected to take a long time. An increase in the number of SMSs being sent, emergency calls being made, high priority accesses, and any voice calls is expected.

However, because of large user plane deployments, the 4Rx/4Tx + 4Rx/4Tx + 4Rx/4Tx configuration is supported even for the 20 MHz + 20 MHz + 20 MHz BW combination with a limited number of cells.

Note: Only the 3GPP-defined band and BW combinations are supported. DL CA is only applied for UEs with related UE capabilities. The parallel use of the UL coordinated multipoint transmission (CoMP) might be restricted. Functionality This feature is an extension to the LTE1803: Downlink Carrier Aggregation 3 CC - 40 MHz feature. For more details, see the LTE1803: Downlink Carrier Aggregation 3 CC 40 MHz feature description.

Issue: 01D
Based on the radio admission control (RAC) selection, either one or two SCells for a three-cell-CA candidate UE is added. A three-cell-CA candidate UE can be a twocell-CA candidate UE at the same time. The UE can be configured with one SCell. A UE supporting CA of three cells that is a three-cell-CA candidate is configured with physical uplink control channel (PUCCH) format 3 when one SCell is added. A UE supporting CA of three cells that is not a three-cell-CA candidate is configured with PUCCH format 1bwcs when one SCell is added. The maximum number of UEs with one or two SCells configured is increased. SCell release of one from two SCells configured because of cell lock/shutdown is introduced. The other configured SCell, which is not locked/shutdown, continues to serve the CA UE. The interworking with the nominal bit rate (NBR) is improved. The NBR is allowed in the DL for three-cell-CA candidate UEs. Stepwise SCell activation of two configured SCells because of traffic is introduced. One SCell is activated if traffic first is required. After that, a check is made if the second SCell needs to be activated because of traffic or if one active SCell is sufficient for that UE. The configurable SCell activation conservativeness level for one and two configured SCells is improved. It is recommended to set the sCellActivationCyclePeriod and scellActivationLevel parameters to low values to achieve fast activation for Transmission Control Protocol (TCP) traffic and short response time. The simultaneousAckNackAndCQI-Format3-r11 dedicated radio resource control (RRC) information element is set to true. The periodic channel state information (CSI) is sent on RRC connection on the PUCCH format 3 with positive acknowledgment (ACK)/negative acknowledgment (NACK) if it is supported by the Rel-11 UE. Dropping of the periodic CSI or SCell scheduling restriction to avoid the dropping is not applied for such UEs.

The PUCCH format 3 resource value selection with configurable (one or two) PUCCH format 3 physical resource blocks (PRBs) is introduced. The operator can configure the amount of available PUCCH format 3 resources. The scheduling of single or multiple UEs on three serving cells with new band or BW combinations with configurable CA fairness is supported. The interworking with the peak data rate capping for two active SCells is improved. The following new performance management (PM) counters are introduced: – –

System impact Interdependencies between features This feature is enabled together with the following features: • • • •
LTE1089: Downlink Carrier Aggregation - 20 MHz LTE1332: Downlink Carrier Aggregation - 40 MHz LTE1562: Carrier Aggregation for Multi-carrier eNodeBs LTE1803: Downlink Carrier Aggregation 3 CC - 40 MHz
The interworking with the following features is excluded: • • •
LTE117: Cell Bandwidth 1.4 MHz LTE116: Cell Bandwidth 3 MHz LTE1382: Cell Resource Groups (interworking with DL CA of two serving cells is possible)
The LTE1542: FDD Supercell and LTE1804: Downlink Carrier Aggregation 3 CC - 60 MHz features can be enabled together. The supercell-enabled cells and supercelldisabled cells might affect the CA performance because of coverage mismatch. Therefore, CA relations (CAREL objects) must be planned carefully. In addition, the features addressing CA coverage mismatch scenarios, such as the LTE2006: Flexible SCell Selection feature, should be considered for activation. The LTE1367: Automatic Cell Combination Assignment for Carrier Aggregation and LTE1951: Automatic Configuration Support for CA for Multi-carrier eNBs features do not support CA of supercell-enabled cells and supercell-disabled cells. Thus, manual configuration of CA relations is needed in these mixed configuration scenarios. Impact on interfaces This feature affects the Uu interface as follows: • • •

Impact on network management tools This feature has no impact on network management tools. Impact on system performance and capacity The LTE1804: Downlink Carrier Aggregation 3 CC - 60 MHz feature enhances the single user DL-peak throughput by aggregating three carriers up to 20 MHz + 20 MHz + 20 MHz.
g
Note: The configurable level of SCell activation conservativeness and stepwise SCell activation might reduce the throughput of the CA UEs, but it might be beneficial for other UEs. The following feature enhancements affect the capacity: • •
The number of UEs with one or two SCells configured is increased. This has also an impact on the number of RRC_CONNECTED UEs in the cells. The number of UEs with one SCell (using PUCCH format 1bcws) or two SCells configured (using PUCCH format 3) per transmission time interval (TTI) per cell is increased because the number of PUCCH format 3 PRBs is increased.

3.12.2 Activating and configuring LTE1804: Downlink Carrier Aggregation 3 CC - 60 MHz Before you start The Activation of downlink Carrier aggregation (actDLCAggr) parameter activates the feature. The Max number of secondary cells for DL carrier aggr (maxNumScells) parameter allows aggregation of three serving cells. Modification of these parameters requires eNB restart. It is recommended to set the Sched Carrier Aggr fairness control factor (caSchedFairFact) parameter value to 0 for the LTE1804: Downlink Carrier Aggregation 3 CC - 60 MHz feature. Table 73

The LTE1804: Downlink Carrier Aggregation 3 CC - 60 MHz feature is enabled together with the LTE1089: Downlink Carrier Aggregation - 20 MHz, LTE1332: Downlink Carrier Aggregation - 40 MHz, LTE1562: Carrier Aggregation for Multi-carrier eNodeBs, and LTE1803: Downlink Carrier Aggregation 3 CC - 40 MHz features. These features use the same activation flag. For more information about feature dependencies, see Interdependencies between features. In operating the CA features, it might be necessary to set the link speed parameter. This is described in the Commissioning Flexi Multiradio BTS LTE document. Note that the default value (Auto) of this parameter is normally the optimal selection. The eNB supports the deployment required for CA. All LNCELs in the eNB must have the Carrier aggregation pool ID (caPoolId) parameter configured when the LTE1804: Downlink Carrier Aggregation 3 CC - 60 MHz feature is enabled. The CA cells with subordinated CAREL or CA cells linked by CAREL-lcrId of another LNCEL must have the same CA pool ID. If there are more than two cells per sector, each cell can have multiple CARELs and each cell can be linked by CAREL-lcrId of other multiple cells. The maximum number of SCell candidates per PCell is two. Multiple CARELs of one cell do not point to the same cell. The following parameters must be set before activating the LTE1804: Downlink Carrier Aggregation 3 CC - 60 MHz feature: • •
160
The PUCCH bandwidth for CQI (nCqiRb) parameter must have a value greater than 1. The Number of PUCCH PRBs for HARQ format 3 (nPucchF3Prbs) parameter must have a value greater than 0.

Additional hardware requirements This feature requires no new or additional hardware. Functional description A mobility profile contains lists of allowed target LTE and inter-RAT frequencies/bands that are used for a UE's mobility. The eNB selects the mobility profile by comparing one of the following values with the moPrMappingList LNCEL parameter: • •
g
a UE's Subscriber profile ID (SPID) received from an MME - introduced with the LTE490: Subscriber Profile-based Mobility feature a UE's serving public land mobile network (PLMN) Note: A virtual SPID introduced with the LTE486: PLMN ID Selected Mobility Profiles is replaced with the LTE1905: PLMN ID and SPID Selected Mobility Profiles feature.
•
a UE's serving PLMN ID and SPID - introduced with the LTE1905: PLMN ID and SPID Selected Mobility Profiles feature
The moProfileSelect parameter values When the LTE1905: PLMN ID and SPID Selected Mobility Profiles feature is enabled (the actSelMobPrf parameter is set to true), the eNB's behavior depends on the profile selection method indicated by the moProfileSelect LNBTS parameter, the configuration in the moPrMappingList LNCEL parameter, the UE's serving PLMN, and the SPID value, if provided by the MME. For the moProfileSelect=spid, the eNB uses the SPID value if provided by the MME and searches the mobility profile in the moPrMappingList table, using the SPID value. It ignores the PLMN value in the table. If a match is not found, or the SPID was not received from the MME, the default mobility profile is used. For the moProfileSelect=plmn, the eNB uses the serving PLMN ID of the UE to search the mobility profile in the moPrMappingList table. It ignores the SPID value if it was provided by the MME. If a match is not found, then the default mobility profile is used.

FDD-LTE15A, Feature Descriptions and Instructions
Descriptions of radio resource management and telecom features
For the moProfileSelect=combined, the eNB uses the serving PLMN ID and the SPID to search the profile in the moPrMappingList table as follows: •
•
If both the PLMN ID and SPID values are available, the eNB looks up the table, using both the PLMN ID and SPID first to find a match. If the match is not found, then the eNB looks up the table, using only the SPID to find a match. The PLMN is then represented by an empty wildcard on a mobility profile mapping list. If the match is not found, then the eNB looks up the table, using only the PLMN ID to find a match. The SPID is then represented by an empty wildcard on a mobility profile mapping list. If the match is not found, then the default profile is used. If only the PLMN ID value is available (the MME did not provide any SPID value), the eNB looks up the table, using only the PLMN ID to find a match. If the match is not found, then the default mobility profile is used.
In all cases, if an entry is found in the moPrMappingList table, the moPrId from the entry is used to find the mobility profile; otherwise, the MODPR is used. Mobility profile mapping table The mobility profile mapping table is extended with the PLMN ID (the mcc, mnc, and mncLength) attributes in addition to the spid and spidLast attributes. These attributes are used as a key to search the mobility profile identifier that points to the actual mobility profile. System impact Interdependencies between features •
LTE490: Subscriber Profile-based Mobility The LTE1905: PLMN ID and SPID Selected Mobility Profiles feature is enabled only when the LTE490: Subscriber Profile-based Mobility feature is enabled, and moProfileSelect=plmn or moProfileSelect=combined.

Additional hardware requirements This feature requires no new or additional hardware. Functional description Concept of frequency layers in the LTE1942 feature The LTE1942: Dedicated VoLTE Inter-frequency Target Frequency List feature introduces a mechanism to control which target layers are used for inter-frequency handovers (HO) during ongoing VoLTE (Voice Over LTE) calls. When the LTE1942 feature is enabled, the eNB uses a specific dedicated target list of frequencies for all types of inter-frequency handovers (including coverage, load, and service-based HOs), both inter- and intra-eNB.
g
Note: All eNBs within the same network should be configured with the same list of frequencies allowed for VoLTE handovers. Examples of how the frequency layers can be defined, and how it influences the handovers are shown in Figure 10: Example of frequency layers in the LTE1942 feature. Figure 10

Target frequencies list in the LTE1942 feature The LTE1942: Dedicated VoLTE Inter-frequency Target Frequency List enters a new list inside mobility profiles (MOPR) and mobility default profile (MODPR) objects to configure a dedicated VoLTE inter-frequency target list. This list is used during inter-frequency handovers for UEs with an established QCI1 bearer (after establishment of bearer with QCI1 and in case when QCI1 is already established with Initial Context Setup) or UEs with established QCI1 entering cell via handover or RRC connection re-establishment. Configuration of the list is performed by the operator using Frequency layer list for ded. VoLTE inter-frequency HO parameter. Only target frequencies layers configured in the LTE1942 list are taken into account before an HO by eNB for: • •
measurement configuration measurement reports filtering
During a target cell selection, the eNB prevents the UE with an established QCI1 bearer from being handed over to a target cell which is not located on a dedicated VoLTE target frequency layer.

Note: At least the default mobility profile (MODPR) has to be created with the LTE1942 list to make inter-frequency VoLTE handovers possible. System impact Interdependencies between features

•
If LTE490 is deactivated and the Auto adaptation to freq. layers of all neighbour cells (autoAdapt) is configured with the value 'true,' the VoLTE inter-frequency handover is not allowed. If LTE490 is activated and the UE cannot be mapped to a mobility profile where the Auto adaptation to freq. layers of all neighbour cells (autoAdapt) is configured with value 'true,' the VoLTE inter-frequency handover is not allowed. Otherwise, the configuration in the mobility profile will be used.
LTE1170: Inter-frequency load balancing: The LTE1170/LTE1531/LTE1387 feature bundle provide load balancing for interfrequency targets and the LTE1841 feature provides load equalization using LB HO. They can be activated in parallel with LTE1942, however if QCI1 is established only target frequencies from LTE1942 shall be used. If LTE1942 is enabled and QCI1 is established, then list of allowed targets for inter-frequency handover is reduced to dedicated target list for VoLTE.

Additional hardware requirements This feature requires no new or additional hardware. Functional description Dynamic blacklisting is applied to every type of intra-LTE inter-eNB handover, except for emergency services. Target cells are temporarily blacklisted for a handover in one of the following cases: •
•
The handover preparation supervision timer (TX2RELOCPrep for an X2 handover or TS1RELOCPrep for an S1 handover) expires after several consecutive handover preparation attempts. The number of HO preparation attempts is operatorconfigurable. The handover preparation is rejected by the target eNB with one of the following cause values: – – –
Radio Network Layer Cause (Cell not Available) Miscellaneous Cause (Control Processing Overload) Miscellaneous Cause (Not enough User Plane Processing Resources)
Handover Preparation For a handover preparation, the source eNB sends a message to the target eNB (X2AP: Handover Request) or to the target MME (S1AP: Handover Required) and starts the supervision timer for the HO preparation. If the timer (TX2RELOCPrep or TS1RELOCPrep) expires and the target cell does not respond, the source eNB increments an internal target cell-specific counter for HO preparation timeouts. If no HO preparation has timed out before, the counter is initialized with 1. The operator can configure the counter. If the counter reaches the threshold: • •
The source eNB starts the timer for dynamic blacklisting of the target cell. The source eNB resets the internal target cell-specific counter for HO preparation timeouts to 0.
As a result, one of the scenarios might take place:

DN09185982
Issue: 01D
FDD-LTE15A, Feature Descriptions and Instructions
• •
Descriptions of radio resource management and telecom features
The source eNB suspects the target cell to be a sleeping cell and starts counting the HO preparation timeouts. The source eNB considers the target cell to be a sleeping cell. The target cell is blacklisted for an HO (except an emergency service) as long as the dynamic blacklisting timer is running. The Number of dynamic handover blacklisting occurrences counter is incremented.
If the target eNB responds to the HO preparation request by X2AP: Handover Request Acknowledge, X2AP: Handover Preparation Failure, S1AP: Handover Command or S1AP: Handover Preparation Failure, the source eNB resets the internal target cellspecific counter for HO preparation timeouts to 0. The target cell is not suspected to be a sleeping cell. The target eNB can reject an HO preparation. Then the source eNB starts the timer for dynamic blacklisting of the target cell. The target cell is blacklisted for an HO (except an emergency service) as long as the dynamic blacklisting timer is running. The Number of dynamic handover blacklisting occurrences counter is incremented. When the dynamic blacklisting timer for the target cell is running, the source eNB eliminates this cell from the target cell list. The eNB does not trigger a handover preparation towards the dynamically-blacklisted target cell. Cause values For blacklisting of barred cells or cells with a control plane (C-plane) or user plane (Uplane) overload, the source eNB relies on the cause values within the Handover Preparation Failure message. For an X2 handover: • •
The Nokia target eNB sets the cause values correctly. A foreign vendor's target eNB behavior is unknown.
For an S1 handover: • •
In a pure Nokia environment, for an intra-MME handover, cause values are propagated correctly from the target eNB via the MME to the source MME. If any of the MMEs or the target eNB is from a foreign vendor, the end-to-end behavior is unknown.

Description of LTE2006: Flexible SCell Selection Introduction to the feature The LTE2006: Flexible SCell Selection feature optimizes the UE throughput as well as the SCell resource utilization, changing the current SCell to another suitable one which is detected by the UE with a better radio quality. Benefits End-user benefits This feature optimizes the UE throughput as well as the SCell resource utilization, changing the current SCell to another suitable one with better radio quality which is detected by the UE. This way the UE will be always served by the best possible SCells, without interrupting the CA functionality, which results in faster data transfer. Operator benefits This feature enables a flexible assignment of serving cells in downlink carrier aggregation. The LTE2006: Flexible SCell Selection feature also allows CA in such deployment scenarios where a PCell and a candidate SCell do not fully overlap, and more than one candidate SCell per PCell exists. This refers to scenario #3 from 3GPP TS 36.300.

Additional hardware requirements This feature requires no new or additional hardware. Functional description Functional overview The Flexi Multiradio BTS supports a flexible SCell selection for downlink carrier aggregation for up to three aggregated cells per UE. Up to five SCell candidates can be configured per PCell and up to two carrier frequencies. The candidate SCells with the same carrier frequency shall also have the same frequency bandwidth. The C-RNTI code space is equally partitioned among the eNB cells belonging to the same C-RNTI group and having the same caPoolID. The configuration of the Carrier aggregation pool ID (caPoolID) has the following constraints: •
a maximum of thirteen eNB cells can have the same Carrier aggregation
•
pool ID (caPoolID) PCell and all its candidate SCells must have the same Carrier aggregation pool ID (caPoolID)
The concept of C-RNTI group has been defined to avoid a C-RNTI collision between the PCell and its candidate SCells. The drawback is that it proportionally reduces the CRNTI code space available per cell with the number of cells belonging to the same CRNTI group. SCells are added blindly, according to the respective SCell priority (SCellPrio); from the UE candidate SCells with the same carrier frequency, the one having the highest priority (that is, having assigned the lowest value to the “SCellPrio” parameter in the respective CAREL object) is selected. Together with the blind SCell configuration, an eNodeB activates a measurement event for UEs with according capabilities in order to find a better intra-frequency SCell. The A6 measurement is operator-configurable per carrier frequency according to the respective carrier aggregation (default) profile CA(D)PR. Upon receiving an A6 measurement report, the eNodeB checks whether the reported cell is an SCell candidate for carrier aggregation, and whether it has sufficient resources to serve as an SCell.

DN09185982
Issue: 01D
FDD-LTE15A, Feature Descriptions and Instructions
Descriptions of radio resource management and telecom features
SCell candidates for the flexible SCell functionality are pre-configured cells of the same eNodeB with a different center frequency as the PCell. They are modeled with CAREL objects. After the above-mentioned checks have been passed, the new SCell is configured (replaces the current SCell). All the SCell-related timers and counters are reset with the SCell change. The SCell change does not trigger a PCell change. The functionality is enabled/disabled via O&M settings per eNodeB. System impact Interdependencies between features At least one of the following CA features must be activated/configured before the activation of the LTE2006: Flexible SCell Selection feature: • • • • •

The LTE1382: Cell Resource Groups feature and the LTE2006: Flexible SCell Selection feature exclude each other. Impact on interfaces This feature has no impact on interfaces. Impact on network management tools With the LTE2006: Flexible SCell Selection feature activated, the iSON manager supports carrier aggregation for a PCell up to max of five candidate secondary cells. Each primary cell can have max of five SCells at a given frequency layer. Impact on system performance and capacity This feature impacts system performance and capacity as follows: For some UEs and chip-sets, every SCell configuration/de-configuration and SCell activation/deactivation, as well as every measurement pertaining to the configured SCells, might be accompanied by a PDSCH and PUSCH micro interruption on a PCell. However, since frequent re-configuration should be avoided with appropriate parameter settings, the throughput impairments should be negligible.

Additional hardware requirements This feature requires no new or additional hardware. Functional description Functional overview The LTE2023: User Plane Overload Handling feature is one of a series of features designed to handle overload situations within the eNB. Its aim is to avoid unstable operation of the eNB due to a high U-plane load. The LTE2023: User Plane Overload Handling feature intends to handle as much U-plane traffic or load as possible. It is obtained by: • • • •
avoiding allocation of additional traffic implementing a separate U-plane overload state machine using the existing overload counter-measures adding the additional counter-measures
The high U-plane load, or a U-plane overload, is expected in various situations in which there is a permanent or temporary increase in traffic and users. If the overload cases happen too often, it is advisabe to examine both the traffic and the traffic profile in a more detailed way. The LTE2023: User Plane Overload Handling feature enables issuing warnings about an overload via NetAct or the BTS SM (see Figure 12: U-plane overload handling). Those alarms are generated by the eNB when a U-plane overload state transition varies from U-plane overload level 0 (UPOVL0) to U-plane overload level 1/2 (UPOVL1/2). The alarm is cleared in case of overload state transition varies from UPOVL1 to UPOVL0. The alarms include the start or end time and the type of overload. To avoid spamming, they are generated only in the case a U-plane overload condition lasts longer than one minute. In addition, if the U-plane overload counter-measures are enabled, the eNB handles as much U-plane traffic as possible, even if the traffic demand is above its specification and keeps itself within a stable operating condition.

U-plane overload management The U-plane overload is detected by evaluating a certain overload level metrics. There are the following overload levels for the U-plane overload: •

overload level 0 (normal operation – when the U-plane overload level is zero)
DN09185982
Issue: 01D
FDD-LTE15A, Feature Descriptions and Instructions
• •
Descriptions of radio resource management and telecom features
overload level 1 (graceful overload handling – the goal of these counter-measures is to avoid a further U-plane traffic increase and to reduce the U-plane load) overload level 2 (preserving stability, self-defense U-plane overload handling – the goal of these counter-measures is not only to avoid a further U-plane traffic increase but also to reduce the U-plane load in a non-graceful manner)
The overload detection mechanism allows to differentiate a peak load scenario from a sustained traffic increase. The overload management function realizes the load control loop, including timed-out values for the different load levels and the corresponding overload actions (activation or deactivation). The LTE2023: U-Plane Overload feature triggers the following mechanisms: 1. U-plane overload trigger based on QoS and packet scheduler load control (UPOVT1): The number of UEs which can be scheduled by packet scheduler due to the U-plane load is fewer than the number of UEs which should be scheduled to meet the guaranteed service quality. This trigger is based on the QoS associated with VoLTE calls, as VoLTE is expected to be the most critical service in this aspect. 2. U-plane overload trigger based on the number of UEs to be scheduled and packet scheduler load control (UPOVT2): packet scheduler can schedule only very few UEs per TTI due to the U-plane load; no matter whether the quality of service is impacted or not. 3. U-plane overload trigger based on DL-physical layer overload detection (UPOVT3): DL-physical layer overload might take place, for example, in scenarios with a high load and where each UE uses two code words. In this case U-plane data packets for some scheduled UEs cannot be processed in due time by the DL-physical layer and are not transmitted on the air interface. Table 95

U-plane overload counters and actions In case of overload level 1 (UPOVL1), the eNB performs the following counter actions: •
Issue: 01D
a rejection of low priority radio resource control (RRC) connection requests (establishment cause set to delayTolerantAccess, mo-data, mo-signaling, spare2, or spare1) – UPOVCM1
DN09185982

Descriptions of radio resource management and telecom features
•
FDD-LTE15A, Feature Descriptions and Instructions
a rejection of an incoming non-emergency handover (HO) without a GBR bearer in combination and/or with HO cause other than time critical handover (TCH) or handover desirable for radio reasons (HDFRR) – UPOVCM2
In case of overload level 2 (UPOVL2), the eNB performs the following counter actions: • •
a rejection of low priority RRC connection requests as defined in overload level 1 – UPOVCM1 a rejection of all non-emergency HOs – UPOVCM2
The ‘Miscellaneous cause – not enough user plane processing resources available’ cause value is used in case of a rejection. This feature is not limited to these overload counter-measures only. In addition, it introduces three extra counter-measures to enhance its own effectiveness (in case of overload level 1 and 2): •
a rejection of E-RAB setup requests – UPOVCM3 – –
– – •
the usage of a transmit diversity (TxDiv) transmission – UPOVCM4 –
–
•
initial context setup requests are admitted for all UEs, irrespective of the RRC establishment cause (in case of UPOVL1 or UPOVL1) E-RAB setup requests are admitted if the ARP value of at least one bearer in the E-RABtobesetup list matches the ARP value of emergency or high priority access (in case of UPOVL1 or UPOVL2) E-RAB setup requests are admitted if E-RABToBeSetupListBearerSUReq list contains at least one GBR bearer (in case of UPOVL1) otherwise, E-RAB setup request is rejected
in case of UPOVL1: dynamic switching from the TxDiv or single-stream (onecode-word) transmission to two code words is prevented as long as UPOVL1 is active; the TxDiv transmission mode is used instead in case of UPOVL2: all transmissions are done as the TxDiv transmission mode for all of the already established calls and new incoming calls (that is, all twocode-words transmissions) are switched to the TxDiv mode
a suspension of the sounding reference symbol (SRS) usage for the UL scheduling process – UPOVCM5 –
SRS is suspended as long as UPOVL1 or UPOVL2 is active
The U-plane overload counters The U-plane overload counters measure the time when the eNB is in the U-plane overload level 1 (M8001C299) or in U-plane overload level 2 (M8001C300). In addition, the M8013C66 counter counts the number of signaling connection requests rejected due to the U-plane overload.

Descriptions of radio resource management and telecom features
The LTE1047: C-plane Overload Handling feature uses the same overload philosophy as the LTE2023: User Plane Overload Handling feature, but the two features have separate procedures to handle overload situations. There are also different interactions depending on the same counter-measures enabled for a Cplane and U-plane overload handling. LTE1113: eICIC-Macro If the number of users per TTI is reduced due to eICIC, it is not taken into account for a U-plane overload decision or calculation. LTE1496: eICIC-Micro If the number of users per TTI is reduced due to eICIC, it is not taken into account for a U-plane overload decision or calculation. LTE1117: MBMS In case the number of users scheduled within a TTI will be used as an indication for a U-plane overload, MBMS sub-frames shall be excluded. LTE495: OTDOA In case the number of users scheduled within a TTI will be used as an indication for a U-plane overload, sub-frames carrying PRS shall be excluded.
Impact on interfaces This feature has no impact on interfaces. Impact on network management tools This feature has no impact on network management tools. Impact on system performance and capacity In case the system is operated beyond its specification, or with other traffic profiles, or feature mixes, a U-plane overload might exist. In these cases, the system performance (values such as latencies, handover performance, and success rates as well as individual and cell throughput) will be degraded both with and without this feature having been activated. However, with this feature and counter-measures enabled, this degradation will be done in a definite way. The goal of these counter-measures is to ensure the quality of service for the admitted traffic and a stable operation of the system. In case of a U-plane overload, the system performance might be degraded, especially in cases where the U-plane overload counter-measures are enabled. The main impacts of the different counter-measures concern: • • • • • • • •
radio resource control (RRC) setup success rate uplink (UL) and downlink (DL) cell capacities related to the UL and DL throughput cell capacity with respect to the amount of all UEs in an RRC connected mode and with respect to the activated radio access bearers (RABs) HO success and HO preparation success rate drop rates E-RAB setup success rate U-plane throughput of a single UE in UL and DL MIMO open loop (OL) or closed loop (CL) usage of a dual stream

Considering the measurement results, the eNodeB decides if a dedicated priorities are added to the RRC Release message or not. The LTE2051: Measurement based Idle Mode Load Balancing feature enables the following functionalities: •
•
• •
•
the operator decides whether the LTE target inter-frequency layers configured for IMLB should be measured with A4 IMLB measurements before sending dedicated priorities to the idle mode or not the operator configures reference symbol received power (RSRP) and/or reference signal received quality (RSRQ) thresholds used for checking whether the target cell fulfills the power and quality requirements the eNodeB prolongs an existing inactivity timer to give the UE additional time to perform A4 IMLB measurements if the IMLB algorithm selects an LTE inter-frequency as a primary target and that LTE inter-frequency is allowed to run A4 IMLB measurements, then the eNodeB triggers the UE to start A4 IMLB measurements for that frequency before sending the RRC Release message to the UE if A4 IMLB report is received, the eNodeB checks the RSRP and/or RSRQ parameters of a target cell against the configured thresholds so that a requested minimum power and quality of the target cell is satisfactory before sending dedicated priorities for the idle mode to UE
Conditions for an RRC connection release with a dedicated priority The RRC connection of the UE is released with a dedicated priority (target cell frequency getting the highest absolute priority) if all of the conditions below are true:

•
Descriptions of radio resource management and telecom features
an A4 IMLB measurement report is received before the A4 IMLB measurement timer expires the target cell's RSRP and/or RSRQ parameters are better than the operatorconfigurable absolute value in order to avoid a reselection to the cell with bad RF conditions the target cell's RSRP and/or RSRQ parameters are better than the source cell's RSRP and/or RSRQ increased by the operator-configurable offset (positive or negative) in order to avoid a reselection to a cell with significantly worse RF conditions
Otherwise, a normal RRC connection release without sending dedicated priorities is applied. Data or S1 signaling activity during the A4 IMLB measurements leads to a cancellation of the RRC Release message, and an inactivity timer is reset. Conditions for activating A4 IMLB measurements For the activation of A4 IMLB measurements, the following conditions must be met: • • • • •
the selected LTE target inter-frequency is allowed to run A4 IMLB measurements the UE supports A4 measurements (FGI bits #14 and #25) the RSRP and/or RSRQ thresholds related to the IMLB measurements are configured (relevant parameters are set) there are no ongoing inter-frequency or/and inter-RAT measurements the maximum number of UEs with A4-based measurements activated is not reached
The A4 IMLB measurements are controlled with a supervision timer configured by the operator. If A4 IMLB measurements cannot be applied to the UE, the RRC connection of this UE is released with a dedicated priority determined originally by the IMLB algorithm defined in the LTE1677: Idle Mode Mobility Balancing Extensions feature.

A UE with configured measurement gaps will fail to receive a single SIB transmission with a probability around 15%. The LTE2085: SIB Reception with Parallel Measurement Gaps feature ensures transmission of SI messages at least two times per SI window, which guarantees receiving one SI message per SI window even for UEs with configured measurement gaps. Benefits End-user benefits The LTE2085: SIB Reception with Parallel Measurement Gaps feature enhances the possibility that the end user will receive at least one SIB during an SI window, regardless of whether the measurement gaps are configured or not. It ensures a higher possibility to receive: information regarding INTRA-frequency and INTER-frequency neighboring cells information for re-selection of a cell (for example, handover) ETWS/CMAS notifications/warnings
• • •
Operator benefits The LTE2085: SIB Reception with Parallel Measurement Gaps feature: enables sending the SIB information at least twice at an interval greater than 6 ms within each SI window guarantees ETWS/CMAS notifications/warnings broadcast reception for all UEs enables the UEs to receive SIBs even if they have a measurement gap configured, which is essential in case of warning broadcasts (ETWS, CMAS)

Functional description Functional overview The SIBs carry relevant information for the UE, which helps the UE, for example, to access a cell or perform a cell (re-)selection. They are also used to transmit warning messages; SIB10 and SIB11 carry ETWS notifications, and SIB12 carries the CMAS notification. Measurement gaps are configured for UEs in the cell's handover zone; the measurement gaps are repeated every 40 ms, and they last for 6 ms in DL (7 ms in UL under certain conditions). The starting points of measurement gaps are distributed in time across all

UEs in the cell in order to equalize the UL traffic generated when UEs report their measurement results. This means the UEs with measurement gaps will fail to receive a single SIB transmission with a probability of 6/40 = 15%. The LTE2085: SIB Reception with Parallel Measurement Gaps feature ensures that a UE having measurement gaps activated is able to receive SIBs at least once during an SI window. If the code rate of a SIB message is too high, then two or three transmissions are arranged for this message in the same SI window, see Figure 13: SIB reception with parallel measurement gaps.

With LTE2085: SIB Reception with Parallel Measurement Gaps, an additional transmission is scheduled in order to cover the case of any possible overlap between a measurement gap and transmission of the SI message. Restrictions on the configuration parameters are introduced to avoid an SI window smaller than 20 ms.

Note: From LTE-FDD 15A onward (with the introduction of the LTE2085: SIB Reception with Parallel Measurement Gaps feature), CMAS/ETWS notifications can be activated only if SI window length (siWindowLen) is equal or greater than 20 ms.
g
Note: From RL70 onward, if the SI window length (siWindowLen) parameter is set to 10 ms or higher, basic eNB software sends SIB2 twice per SI window, with transmissions separated by more than 6 ms. The SI window length (siWindowLen) parameter can still be set to smaller values but the reception of SIB2 for UEs with measurement gaps is guaranteed only if the SI window length (siWindowLen) is equal or greater than 10 ms. Activation of the LTE2085: SIB Reception with Parallel Measurement Gaps feature shows an additional effect only for SIB3 and higher. UEs with a certain chipset might experience HO failures under the following rare conditions: •

UEs configured with a measurement gap that covers the subframe in which the small cell sends a system information block (SIB) the SI window length (siWindowLen) parameter is set to 20 ms, therefore, there will be only one subframe available if the SIB window coincides with the first half of the eICIC pattern of a 40-ms duration
UEs with the chipset do not use SIB2 data they were provided as part of the HO procedure. The UEs try to read SIB2 in the target cell and fail if it does not succeed within a preset time. It is recommended to perform one of the following actions to ensure smooth service conditions in HetNet scenarios: • •
Activate the LTE2085: SIB Reception with Parallel Measurement Gaps feature. Set the SI window length (siWindowLen) parameter to 40 ms in all eICIC small cells.
The LTE494: Commercial Mobile Alert System feature supports SIBs 12, and the LTE843: ETWS Broadcast feature supports SIBs 10 and SIBs 11; however, the two features cannot be activated together.

Impact on system performance and capacity The Earthquake and Tsunami Warning System (ETWS) and Commercial Mobile Alert System (CMAS) are rare events, so a duplicated transmission of ETWS/CMAS messages does not consume noteworthy amounts of resources. Further impact depends on the Twofold transmission of SIBs per SI window (sib2xTransmit) parameter.

DN09185982
Issue: 01D
FDD-LTE15A, Feature Descriptions and Instructions
Descriptions of radio resource management and telecom features
The LTE2149: Supplemental Downlink Carrier feature introduces supplemental cells only with downlink channels and not with the physical hybrid-ARQ indicator channel (PHICH). A supplemental cell can be used only as a secondary cell (SCell) in combination with downlink carrier aggregation for LTE. Benefits End-user benefits The LTE2149: Supplemental Downlink Carrier feature provides the end-user with an improved peak and average UE downlink throughput, enhancing the already utilized carrier aggregation features. Operator benefits Using the carrier aggregation feature, the LTE2149: Supplemental Downlink Carrier feature boosts downlink capacity by utilizing an unpaired spectrum as an additional carrier along with the originally paired downlink and uplink carriers. It has a maximum of 30 MHz aggregated bandwidth for a two-band combination downlink carrier and a maximum of 50 MHz aggregated bandwidth for a three-band combination downlink carrier.

Additional hardware requirements The LTE2149: Supplemental Downlink Carrier feature uses new, dedicated radio frequency modules supporting only downlink on band 29: • •
LTE2143: FRBE Flexi RRH 2TX 2RX 750 2TX 720 LTE2266: FRBG Flexi RRH 2TX 4RX 730 2TX 720
Other requirements Because of 3GPP limitation for supplementary downlink carrier cell bandwidth on band 29 must be of 5 or 10 MHz. Functional description Introduction to carrier aggregation in relation to LTE2149 Carrier aggregation (CA) increases the bandwidth by combining two or more component carriers (CC). The individual CCs can be of different bandwidths. Aggregation is possible by using contiguous CCs within the same operating frequency band (intra-band

contiguous). Non-contiguous aggregation is possible either as intra-band with separated CCs of the same operating frequency band, or as inter-band when CCs are from different operating frequency bands. A supplementary cell is a cell operating in the carrier aggregation mode only with downlink channels and not with the physical hybrid-ARQ indicator channel (PHICH) (see Figure 17: A supplementary cell used as a secondary cell (SCell) in carrier aggregation).

CarrierAggregation Feature deployment The LTE2149: Supplemental Downlink Carrier feature allows utilizing an unpaired spectrum in band 29 with a cell bandwidth of 5 or 10 MHz. The feature supports up to 400 configured and activated secondary cell (SCell) UEs in a supplemental cell. The LTE2149: Supplemental Downlink Carrier feature supports the following two-band combinations for supplemental cells: • • •
band 2 + band 29 (bandwidth combination set: 0, 1, 2) band 4 + band 29 (bandwidth combination set: 0, 1, 2) band 30 + band 29 (bandwidth combination set: 0)
with a maximum of 30 MHz aggregated bandwidth. The LTE2149: Supplemental Downlink Carrier feature supports the following three-band combinations for supplemental cells: • • •
band 2 + band 29 + band 30 (bandwidth combination set: 0) band 4 + band 29 + band 30 (bandwidth combination set: 0) band 2 + band 2 + band 29 (bandwidth combination set: 0)
with a maximum of 50 MHz aggregated bandwidth. The supplemental cell cannot act as a primary cell (PCell). To avoid camping UEs on the supplemental cell it is declared as barred in system information block 1 (SIB1). System information block 3 (SIB3) is permamently disable and higher SIBs are conditionally

because the carrier aggregation is a precondition. The feature also depends on LTE1803: Downlink Carrier Aggregation 3 CC - 40 MHz and LTE1804: Downlink Carrier Aggregation 3CC - 60 MHz as a precondition for the three-band combination carrier. The feature depends on LTE2006: Flexible SCell Selection defining SCell selection for the supplemental downlink carrier. The feature must be activated together with LTE1089: Downlink Carrier Aggregation - 20 MHz and LTE1332: Downlink Carrier Aggregation - 40 MHz.

Impact on system performance and capacity The LTE2149: Supplemental Downlink Carrier feature can improve peak and mean-user download throughput of non-GBR UEs with the secondary cell (SCell) configured. Additionally, a system capacity gain is also expected. The actual gain depends on many factors; for example, network's load, level of GBR traffic, parametrization of the scheduling fairness factor, but it can be doubled for bandwidth combinations with an equal bandwidth of two involved cells.

Additional hardware requirements This feature requires no new or additional hardware. Functional description Functional overview The eICIC feature requires synchronization on the subframe level because of the application of the almost blank subframe (ABS). The maximum tolerable phase error for eICIC is 5 μs. The LTE2208: eICIC Enhancements - micro feature handles the loss of eNB synchronization as follows: • • • • • •
The LTE1496: eICIC - micro feature is enabled in the small cell and an eICIC partnership is established in the macro cell. If the eNB looses all the synchronization reference signals, it will continue to operate in holdover mode. The eNB continuous to monitor the estimated phase error. When the estimated phase error exceeds 5 μs for more than two minutes, an alarm will be raised. Synchronization is lost in the eICIC operation. The eICIC partnership is terminated.
The ABS pattern is switched off after all the eICIC partnerships are terminated. The eICIC feature remains enabled in the small cell and the eICIC partnership can be established again and operation will be resumed once the synchronization is recovered. The requests for eICIC partnership establishment are rejected as long as the phase error remains higher than 5 μs. The LTE2208: eICIC Enhancements - micro feature also deals with the dedicated SIB1 signaling for R11 UEs that are connected to the small cell. It handles the SIB1 update case for UEs located more than 6 dB in the small-cell cell range expansion (CRE). Dedicated signaling for the SIB1 update is sent when there is a modification in the SIB1 content. The updates are sent periodically to ensure that CRE UE receives the dedicated signaling. The 6 dB CRE limit is considered the safe value for UEs to read the PDCCH when receiving SIB1. The small cell CRE UEs encounter a high inter-cell interference from the macro cell when decoding SIB1 data on the PDCCH. However, because of the application of ABS, the PDSCH is blanked in the macro cell. This advantage, together with the R11 UE capability, is used to update SIB1 through dedicated RRC signaling to R11 UEs located more than 6 dB in the small cell CRE. The small cell eNB reconfigures all qualified UEs. System impact Interdependencies between features This feature is enabled together with LTE1496: eICIC - micro feature.

FDD-LTE15A, Feature Descriptions and Instructions
The LTE2305: Inter-eNodeB Carrier Aggregation for 2 Macro eNodeBs feature allows DL CA for cells that are hosted in two different co-located macro eNodeBs. This is needed to support large configurations that require CA across multiple eNodeBs. The eNodeBs are connected together with a sync and a serial rapid I/O (SRIO) cable. The sync cable provides synchronization of the information required to keep the two eNodeBs in phase sync. The SRIO cable is used for signaling messages and bearer data transfer between the eNodeBs for CA. The interconnected eNodeBs can still act as an independent eNodeB toward the core network, other eNodeBs, and the LTE OMS or NetAct. This feature is activated using the Activate inter-eNB DL carrier aggregation (actInterEnbDLCAggr) parameter. CA cluster The eNBs connected together for the purpose of inter-eNB CA are referred to as a CA cluster. The CA cluster is loosely coupled so that if one eNB fails, the other eNB remains operational; or if the SRIO cable fails, both eNBs remain operational, but the inter-eNB CA is disabled. An alarm is introduced to indicate an SRIO link outage. The following changes are introduced in the eNB CA cluster management as compared to the management of individual eNBs: • • •
The eNB software interface versions must be compatible within the eNB CA cluster. The CA cluster must be configured by assigning a common CA cluster ID and a unique CA cluster member ID to each eNB in the CA cluster. The value of the set of parameters for the LTE2305: Inter-eNodeB Carrier Aggregation for 2 Macro eNodeBs feature must be consistent between all eNBs in the CA cluster.
The operator configures the CA cluster topology (Carrier aggregation cluster ID parameter) using the NetAct Configurator tools. This topology identifies which eNBs are connected together in the CA cluster. The operator has the option to perform consistency check using CM Analyzer in the NetAct Configurator. In the NetAct Configurator, a new CM Analyzer Nokia-defined rule set (Nokia.InterENodeBCarrierAggregation) is introduced for the LTE2305: Inter-eNodeB Carrier Aggregation for 2 Macro eNodeBs feature to verify the consistency of some of the parameters between all eNBs in the CA cluster. For more details about the rules, see the rule descriptions in the CM Analyzer application user interface. Parameter inconsistency alarm Each eNodeB in the CA cluster raises the EFaultId_InterEnbCaParamsInconsistencyAl alarm if the Activate intereNB DL carrier aggregation (actInterEnbDLCaggr) parameter is set to true and the required parameters between the eNodeBs are inconsistent. The activation of the new configuration in each eNodeB does not happen at the same time, and therefore it is possible that the alarm is raised for a short-time interval. This indicates the transient period when the inter-eNodeB CA is disabled because the eNodeBs are not synchronized with consistent parameters. The alarm persists in a scenario where the configuration of the parameters between the eNodeBs in the CA cluster is inconsistent. In this case, the erroneous configuration must be identified using the CM Analyzer check or with the information given in the alarm. If the CM Analyzer check does not report a consistency error, the erroneous configuration needs to be identified manually. Once the error is identified, the configuration plan needs to be corrected accordingly and provisioned to the eNodeB that has the error. The nature

It enables the operator to prioritize the sequence of broadcast control channel (BCCH) carriers within the GERAN frequency layer list. In the case of some operators, prior to this feature, the fixed sequence of BCCH carriers caused the UE to select suboptimal cells. With LTE2314 activated, the UE choses an optimal GERAN cell. Benefits End-user benefits This feature increases call success rate. Operator benefits This feature enables the operator to configure a unique priority value for a single absolute radio frequency number (ARFCN).

Functional description The LTE2314: Configurable Sequence of BCCH Carriers within GERAN Frequency Layer List for CSFB Based on UE Context Release feature enables the operator to prioritize the sequence of broadcast control channel (BCCH) carriers within the GERAN frequency layer list. In the case of some operators, prior to this feature, the fixed sequence of BCCH carriers caused the UE to select suboptimal cells. With LTE2314 activated, the UE choses an optimal GERAN cell. This feature is an extension of the LTE562: CSFB to UTRAN or GSM via Redirect feature. GERAN BCCH carrier frequency priority is O&M configurable and no duplication is allowed within configured carriers' priorities. Carriers without defined priorities are treated as the lowest priority carriers and are added at the end of the sequence list. After the operator has configured the priority of ARFCN values, the eNB sends a sorted list to the UE. When there is no priority set for BCCH carriers, the functionality of this feature switches off. System impact Interdependencies between features For the LTE2314: Configurable Sequence of BCCH Carriers within GERAN Frequency Layer List for CSFB Based on UE Context Release feature, the LTE562: CSFB to UTRAN or GSM via Redirect feature must be enabled. The LTE562 feature is used to keep circuit-switched (CS) service voice continuity in the initial phase of LTE implementation, which does not support CS services. As a consequence of this feature, the UE leaves an LTE network and is handled by radio access technology (RAT), capable of the CS service. Impact on interfaces This feature has no impact on interfaces. Impact on network management tools This feature has no impact on network management tools. Impact on system performance and capacity This feature impacts system performance and capacity as follows: • •

Descriptions of radio resource management and telecom features
This feature ensures end users' mobiles greater flexibly since they support more band combinations (more than 128 different band combinations); thus, end users may experience higher throughput. Operator benefits This feature allows the operator to reduce the number of 3CC band combinations sent from UE to eNB based on the priority list provided by the operator. Moreover, it enables the operator to avoid the latency introduced from the IDLE to ACTIVE transition because the eNB would have the available UE capabilities at initial attach. Without this feature implemented, the operator may not be able to provide the 3CC carrier aggregation to the end user if the band combinations of the operator's network are not contained in the UE capabilities sent from UE to eNB.

Additional hardware requirements This feature requires no new or additional hardware. Functional description The LTE2324: Network-requested UE Radio Capabilities feature introduces an operator configurable list of required carrier aggregation (CA) bands. The additional CA band combinations (supportedBandCombinationAdd) are valid only for 3CC band combinations. This feature enables the UE to provide additional 256 supported CA band combinations upon the eNB's request compared with the currently available 128 band combinations. If the initially provided UE radio capabilities are not sufficient to configure CA in the eNB, a dedicated UE capability enquiry with carrier aggregation bands will be initiated for UEs with suitable capabilities. The feature can be enabled/disabled per eNB through the O&M settings. Operation of the LTE2324: Network-requested UE Radio Capabilities feature consists of the following two mechanisms: • •
filtering, where the eNB requests the UE to provide supported band combinations within a limited set of bands adding a supportedBandCombinationAdd list in the UE-EUTRA-Capability, enabling additional 256 CA band combinations in a UE capability signalling

Additional hardware requirements This feature requires no new or additional hardware. Functional description The LTE2430: QCI1 Establishment Triggered Protection Timer feature enables a configurable QCI1 protection timer. The timer is used for preventing the UEs from falling into the RRC idle mode during a ringtone, when there is potentially no traffic on any of the bearers or on the S1 link. However, if the protection timer and all other inactivity timers expire before the ringtone is finished, the UE is released to the RRC idle mode. The timer is started or restarted by an eNodeB every time the QCI1 is established. The intention is to set the timer value higher than a normal user plane inactivity timer; it should be set according to the time that the end-user is expected to answer the call when the phone is ringing. In this scenario, the UE is not released to the RRC idle mode until the established QCI1 timer and all other inactivity timers expire. In case the end-user terminates the call, and no other QCI1 related to that UE is established, then the QCI1 protection timer stops. Consequently, if additionally all other inactivity timers expire, the UE is released to the RRC idle mode. The value of QCI1 protection timer is defined with the QCI1 protection timer (qci1ProtectionTimer) parameter.

Essential for the LTE942: Hybrid Synchronization feature are two new functional block elements: •
•
SnycE estimator functional block: The SyncE estimator block requires the provision of a new algorithm which keeps the phase error at a constant value. This property cannot be achieved by the algorithm currently used in the 2MHz frequency synchronization block. Estimator selection block: the estimator selection block is required to separate the input data to the tuning block depending on if the primary sync source is available or not.
Figure 18: Hybrid Sync, GPS1pps/ToD + SyncE, normal tuning illustrates a normal tuning of hybrid synchronization with GPS1pps/ToD as the primary source. The GPS1pps signal is ok; therefore, the estimator selection block decides - that the the GPS1pps as the primary source is taken as the synchronization source. Figure 18

Furthermore, the tuning block has to be modified to become aware of the LTE942: Hybrid Synchronization feature. In case the LTE942: Hybrid Synchronization feature is activated, and the primary sync source is lost, it has to use the phase and frequency error estimation which is provided by the SyncE estimator and is linked to its input by the estimator selection unit to enable the assisted holdover mode. Additionally, in case the secondary, that is the SyncE source is lost, the tuning block has to fall back to a normal holdover mode. If the primary sync source is lost, the already implemented ReferenceClockMissing fault is raised with severity minor and sent within the BASE STATION NOTIFICATION alarm. If both - the primary sync source and the secondary sync source (SyncE) are lost, the ReferenceClockMissing fault is raised with severity major and sent within the BASE STATION OPERATION DEGRADED alarm.

Benefits End-user benefits This feature does not affect the end-user experience.

Additional hardware requirements This feature requires FSMr3 or FZM hardware. Functional description Functional overview The LTE1244: Source-based Routing in BTS feature extends the routing decision for egress IP packets to take also the source address of IP packets into account. Although the feature is intended for U-plane traffic, it is applicable to all traffic planes. In fact, the feature is applied to all egress unicast IP packets, independent of the application creating the packet. It is also applied to packets received at the LMP and routed to the backhaul. The feature is not applied while routing traffic to the eNB subnet. The feature is applicable to IPv4 as well as IPv6 packets. When the IP packets have to leave the eNB on two different physical interfaces, this has to be achieved by configuring the relation between network IP interfaces and physical interfaces accordingly. For example, two network IP interfaces with different VLAN IDs can be used and the switching functionality can be configured so that each VLAN is accepted on one physical interface only. As a precondition, the IP packets need to have different IP source addresses to be routed differently. Especially if U-plane packets are to be routed differently based on their source address, there need to be different U-plane addresses in the eNB. Multiple Uplane IP addresses are provided by the LTE505 Transport Separation for RAN Sharing or LTE1771 Dual U-plane IP Addresses feature, for which the LTE1244: Source-based Routing in BTS feature is a prerequisite. Route lookup More than one routing table can be configured. Each routing table can contain static routes, used for ordinary destination-based routing using the longest prefix match. A twostep route lookup is used (following the Linux implementation): •
•
Step1: use policies to determine one out of several routing tables. The policies take the source IP address into account (policies are specified with a subnet, see Configuration example). Step2: based on configured routes in each routing table, the destination-based routing with the longest prefix match is used. When no route is found in a table, the search continues with the next policy.
One routing table is considered the main one; all packets for which no policy or no route is found are handled by the main table. Therefore, when the configuration of policies is omitted, then the same behavior as without this feature is achieved. There is a main routing table for each of IPv4 and IPv6. The main routing table is identified by the id 1 of the managed object. In the system, direct routes are added automatically to the main
Issue: 01D
DN09185982

FDD-LTE15A, Feature Descriptions and Instructions
routing table, but not to the additional routing tables. Without direct routes, IP packets for directly connected hosts might be sent to the next-hop gateway first. To avoid this behavior, direct routes have to be added to the additional tables too. A policy consists of an IP subnet and a pointer to a routing table. An IP packet matches a policy when its source address is within the subnet; the packet is routed according to the entries of the routing table to which the policy is pointing. Policies are looked up in a fixed order. The order of policies is defined by the operator. In case the subnets of the policies do not overlap, only one of the additional routing tables, and potentially the main table, is searched for routes. Example: The eNB is configured with two U-plane addresses, 10.1.1.1 and 10.1.1.5, and there is just one SAE-GW with an IP address 20.1.1.1 (a specific IP address from the 20.1.1.0/30 subnet). Each of the two routing tables Tbl_2/3 contains just one route towards the SAEGW, but with different next-hop gateways (10.1.1.2 and 10.1.1.6). The main routing table contains in this example just a default route to some next-hop gateway with an a.b.c.d address. Figure 22

An egress IP packet with a 10.1.1.5 source address would match the second policy, and, therefore, Tbl_3 would determine the routing; the next-hop gateway for this packet has a 10.1.1.6 IP address. In this example, there is no need to configure direct routes in the additional routing tables because the only other host in the subnets of the network interfaces is the respective next-hop gateway.

Optional: new network interfaces are configured, Ethernet switch configured in eNB, including VLAN filtering. Next-hop gateways in the mobile backhaul reconfigured to allow use of new network interface. One or more additional routing tables are created. Static routes are added to these routing table(s). Routing policies are added to the routing policy table, establishing a mapping of IP subnets to the new routing tables or the main routing table. It is expected that at least some of the application addresses match the routing policies.
Parameter configuration The operator edits the delta plan file and configures at least the following parameter:
g
Note: The order of steps is relevant to avoid routing policies pointing to not yet created routing tables (such policies will not be allowed). •
the Routing policies (routingPolicies) parameter contains the following further parameters: – – – –
Order number of policy (OrderNumber) Reference to routing table (routingTablePtr) Source IP address (srcIpAddress) Source IP Prefix Length (srcIpPrefixLength)
The operator downloads and activates the plan file. The eNB persistently stores the parameter values. The eNB informs NetAct and BTS Site Manager about the changed configuration via notifications. Alarms: There are no alarms for this feature. Measurements: There are no dedicated measurements. IP IF specific counters can be used to check whether there is the expected amount of traffic on different interfaces. Post-conditions: Egress packets are routed according to the new routing configuration. The routing table from the precondition is considered the 'main' routing table (for example see figure Configuration example with two U-plane addresses. The eNB is using the LTE1244: Source-based Routing in BTS feature. User scenario: Source-based routing (with Dual U-plane and SCTP multihoming) An eNB is configured with two separate U-plane addresses, each on its own VLAN. A third VLAN is used for M and S-plane. Two C-plane addresses are used (SCTP multihoming) to illustrate the combined use of the features. One routing policy is used for each of the U-plane addresses. The M/S-plane traffic are handled by the main routing table. The MME IP addresses are from two disjoint subnets. Each C-plane address is used to communicate with peer MMEs in one of the two MME subnets. The traffic can be distributed to two physical interfaces by the switching functionality, but this has been omitted from this scenario for the sake of simplicity. A neighboring eNB, as shown in the diagram, connected via Ethernet.

For example, the network interface IP addresses are in the respective VLANs and in the same subnet. The X2 traffic among the two eNBs is exchanged directly among the two eNBs; it is not sent by the source eNB to the gateway first and by the gateway to the target eNB. Figure 23

Detailed configuration Three VLANs are configured in the eNB with the following IP addresses: VLAN ID 11: 10.1.1.1/24 VLAN ID 12: 10.1.2.1/24 VLAN ID 13: 10.1.3.1/24 These network IP addresses are also used as application addresses: • • •
U1-plane, C1-plane (cPlaneIpAddress): 10.1.1.1 U2-plane, C2-plane (cPlaneIpAddressSec): 10.1.2.1 M-plane, S-plane: 10.1.3.1
The MME IP addresses are from the 20.1.2.0/24 subnet. They are divided into two subnets: MME1 20.1.2.0/25 and MME2 20.1.2.128/25. SCTP messages are intended to be exchanged among C1 and MME1 as well as C2 and MME2 respectively. Each of the routing tables contains just one default route, sending the traffic via different next-hop gateways. Both C-plane IP addresses are used on S1 for SCTP. On X2 just one C-plane address is used, which is C1 (cPlaneIpAddress), 10.1.1.1. To indicate which local C-plane address for S1 is used towards which MME, IP static routes are configured in the main routing table with the preSrcIpv4Addr parameter. The actual routing of packets uses the routing policies and the routes in the respective routing tables to determine the egress interface and next hop for the packet with the selected local C-plane address. When the source-based routing is used without the SCTP multihoming, there is no need to fill in this parameter. A direct route has to be configured in the additional IPRT-2 routing tables, which is used for X2 traffic of both the U-plane and C-plane. The network interface is a /24 subnet containing neighboring eNBs. Without the direct route, the traffic among neighboring
276

Descriptions of transport and transmission features
eNBs would be sent to the next-hop gateway with the 10.1.1.253 address first. As there is no X2 traffic among the eNB and neighburing eNBs on VLAN 12, it is not strictly needed to configure a direct route in IPRT-3. Nevertheless, it is recommended to do so to keep the routing tables similar.

Note: It is not possible to configure the preSrcIpv4Addr parameter in the direct routes in the main table; these routes are configured automatically by the eNB.

4.3 LTE1559: SCTP Enhancements 4.3.1 Description of LTE1559: SCTP Enhancements Introduction to the feature The LTE1559: SCTP Enhancements feature enables enhanced configuration options of eNB Stream Control Transmission Protocol (SCTP) endpoints. Benefits End-user benefits This feature does not affect the end-user experience. Operator benefits The LTE1559: SCTP Enhancements feature introduces user-configurable parameters and new counters for the SCTP protocol. Before the introduction of the LTE1559: SCTP Enhancements feature these SCTP parameters were hard-coded. This feature enables the operator to: make the eNB's SCTP behavior more flexible and more controllable. impove the interoperability with other vendor's eNBs, MMEs and the transmission network. align eNB SCTP configuration parameters with peer SCTP endpoints such as MME or other vendor's eNBs. apply the same set of SCTP configuration parameters across all eNBs if they have eNBs from Nokia and other vendors for maintenance reasons (for example network planing, operability). optimize eNB SCTP configuration parameters to improve the end-to-end quality for example more successful inter-eNB handovers.

Additional hardware requirements This feature requires no new or additional hardware. Functional description Functional overview All the GTP-U path management messages are supported by the eNB for both the main local GTP-U path endpoint and the second local GTP-U path endpoint. One example of these messages is the GTP-U Path Supervision’s ECHO REQUEST/RESPONSE message. The X2-U-plane traffic of a UE uses, furthermore, only one IP address, which is always mapped to the main U-plane address U1. S1 GTP-U Path Supervision - Dual U-plane IP addresses When the operator has activated the GTP-U path supervision to an S-GW's IP address, the eNB supervises both GTP-U paths towards that S-GW, in parallel. The existing alarm for S1 GTP-U Path Failures is extended so that the eNB can indicate the specific failed GTP-U path to the S-GW. In case of a GTP-U path failure, the specific failed GTP-U path is indicated in the alarm message by the starting and the endpoint of the specific GTP-U path. When one GTP-U path is not available anymore to the S-GW, the eNB raises the “GTP-U Path Failure” fault (alarm), indicating the specific GTP-U path. The severity is ‘major’, and the reported alarm is 7657 BASE STATION CONNECTIVITY DEGRADED. When also the second GTP-U path is not available to the S-GW, the eNB raises the “GTP-U Path Failure” fault (alarm), indicating the specific GTP-U path. The severity is ‘major,’ and the reported alarm is 7657 BASE STATION CONNECTIVITY DEGRADED. Feature application scenarios

eNB is up and running. The LTE1771: Dual U-plane IP Addresses feature is not active, a second U-plane address is not configured. The LTE649: QoS-aware Ethernet Switching feature is active. The FSMr3 HW is used. The 1 Gb/s Ethernet is used. The transport network uses IPv4. A single mobile backhaul network is used. The MBMS is not used.
Event The operator wishes to provide more than 1 Gb/s throughput. Two external Ethernet links and two U-plane addresses which the LTE1771: Dual U-Plane IP Addresses feature supports are used. Operator activities: preparatory steps – network planning 1. The operator plans the target network configuration, including IP addresses and Firewall settings; for this example, the final configuration as shown in the figure is supposed to be used. 2. The operator decides how much of the total bandwidth available on both interfaces is supposed to be used for the GBR traffic. For this exemplary scenario, a value of 200 Mb/s is assumed. Operator activities: configuration of the eNB 1. The operator creates a plan file with FAF=false. 2. The operator configures a second U-plane address. 3. The operator configures VLANs and source-based routing (LTE1244: Source-based Routing) to distribute traffic from the two U-plane addresses to physical ports. 4. The operator configures TAC, and he wishes to use the admitted GBR traffic to 200 Mb/s for the GBR traffic.
g
Note: It is recommended that this value is 1Gb/s user traffic. The X2 traffic uses U1 address only. The eNB measures the GBR traffic for both U-plane addresses together and uses this for a transport admission control.
System impact Interdependencies between features The following features have to interact with LTE1771: Dual U-plane IP Addresses in order to establish a higher user data throughput or route user traffic over different network paths: • •
•
• • •
The LTE125: IPv6 for U/C-Plane feature is required to use LTE1771: Dual U-plane IP Addresses with IPv6. The LTE649: QoS-aware Ethernet Switching feature is required in case the traffic is distributed across two physical interfaces, as it provides the needed "independent VLAN MAC address learning". The LTE1244: Source-based Routing feature is needed for correct routing decisions when having a single core destination or IPsec GW destination IP addresses, but using two physical and/or logical interfaces. The LTE866: Fast IP Rerouting feature is recommended for interface resilience; it is mandatory in cases without the IPsec, or it can be used with the IPsec. The LTE1753: Backup IPsec Tunnel feature may be utilized for interface resilience with the IPsec (recommended without the geo-redundant security gateway). The LTE1401: Measurement-based TAC feature is applied to the sum GBR traffic of both U-plane addresses. The operators must consider this in the measurementbased TAC configuration.
Impact on interfaces This feature has no impact on interfaces. Impact on network management tools This feature has no impact on network management tools. Impact on system performance and capacity The LTE1771: Dual U-plane IP Addresses feature is used to increase the user data throughput of the network between eNB and SGWs; for example, if the 2x 1GE is used for connecting an eNB to the transport network, theoretically up to 2 Gb/s can be achieved.

The feature is used for BTS site locations that are not optimal for satellite-reception. Benefits End-user benefits This feature does not affect the end-user experience. Operator benefits This feature allows operation with connectivity to only one GNSS satellite (versus four that are typically required). This can be particularly beneficial for indoor deployments (such as indoor FzM) or BTSs in urban canyons that tend to deal with poor GNSS reception.

Functional description Functional overview A GPS is a space-based radio-navigation system that provides precise threedimensional (3D) positioning (latitude, longitude, altitude) by using time signals transmitted from satellites. The signals also allow the receivers to calculate the current

local time with great precision, which allows time synchronization. This satellite navigation system with global coverage is called a Global Navigation Satellite System GNSS). Typically, a minimum GPS constellation is arranged so that a minimum of 4 satellites are in an unobstructed view to determine latitude, longitude, altitude, and the time for a BTS as demonstrated below: Figure 28

When a BTS is placed in environments with poor reception of the minimum four GPS satellites, it can result in a huge BTS initialization time increase, or it may fail to be initialized at all. This feature enables the user to enter manually the position coordinates for the GNSS-receiver antenna in a BTS. This improves the system's availability in locations with an obstructed GNSS antenna visibility and allows the Flexi Zone Micro BTS to operate in locations that otherwise might have been prohibited. The user fills in the BTS location data based on the GPS satellite coordinate information via position survey method. Four user-configurable GPS location parameters are introduced: • • • •
GNSS receiver altitude (altitudeConf) GNSS receiver latitude (latitudeConf) GNSS receiver longitude (longitudeConf) Location mode (locationMode)
When a BTS is in an environment with as few as one satellite, the user can set the Location mode (locationMode) to surveyed. Then the user can manually enter the BTS location parameters: GNSS receiver latitude (latitudeConf), GNSS receiver altitude (altitudeConf), and GNSS receiver

longtitude (longitudeConf). With time information obtained from one satellite which is accessible, this method allows the GPS to calculate the current local time with great precision, which allows time synchronization. The operators have various methods available to collect the coordinate information of the GPS satellite. Below, there are a few examples: • •
•
using a surveyor company using a hand-held GNSS receiver at a nearby location; a calculation which is based on the nearby location's coordinates and the distance of the measured location from the actual BTS using Nokia HERE map
The GNSS receiver latitude (latitudeConf) and GNSS receiver longtitude (longitudeConf) data should be accurate to within +/-1 s (+/-30 m) when operating in the surveyed mode, using the World Geodetic System 1984 (WGS84) coordinate system. The GNSS receiver altitude (altitudeConf) data should be accurate to within +/-30 m when operating in the surveyed mode relative to a GPS ellipsoid. The surveyed mode should be used with extreme care and only in situations where it is impossible or impractical to install the GPS antenna in a position where it can typically receive four or more satellites for a significant period of time. The surveyed mode does not reduce the satellite acquisition time and should not be used for this purpose. The use of the surveyed mode needs to be used with caution as any errors in the supplied location data beyond the specified limits can result in significant timing errors or erratic GPS receiver operation. User scenario: enter BTS location manually from NetAct This user scenario describes a NetAct user manually entering the GNSS antenna location while the BTS is in a challenging environment with less than four satellite transmissions available. Actors Technician: the user attempting to manually enter the GNSS antenna location from NetAct Pre-conditions • •
The user is able to manually collect the BTS location information. The time information is obtained from at least one of the satellites.
Main flow • •
The user sets Location mode (locationMode) to surveyed. The user enters the manually collected BTS location information to GNSS receiver latitude (latitudeConf), GNSS receiver longtitude (longitudeConf), and GNSS receiver altitude (altitudeConf).

Additional hardware requirements No new or additional hardware is required. Functional description To be compliant with the 3GPP recommendation TS 33.401, the eNB checks the origin and integrity of any software package installed in it. The LTE790: Signed SW feature ensures that the software package has not been altered after leaving the factory. This functionality enhances an already implemented software verification procedure introduced by LTE940: SW Verification Agent. Software verification procedure The software verification procedure is shown in figure below.

The software is distributed to customers using Nokia Online Services (NOLS). The customer then may use the NetAct or BTS Site Manager to install software in an individual eNB. Software verification starts after it has been downloaded to an eNB. The first file examined by the eNB is the hash container in TagetBD.xml. First the signature and then the hash value of the hash container itself is examined. The signature must be provided by an entity that can be verified by a Nokia trust chain. If an eNB hash container file or its signature file is not present, or the verification of the signature failed, the Failure to verify the signature of a signed software release fault occures, and the base station notification alarm is raised. As a result, software download fails and must be re-tried. If the hash container files pass verification, the eNB examines all new or modified files. For each individual file, the eNB calculates a hash value and compares it with the hash value stored in the hash container file. If hash validation failed or the hash value is missing, the Failure to verify a signed software release fault occures, and the base station notification alarm is raised. As a result, software download fails and must be re-tried. If the values are matching, it means that the software has not been modified in any way and can be safely used by the eNB. If all individual files pass an integrity check, the eNB stores the signatures received with the signed SW download together with the software package in a non-volatile memory. The local signature is needed for the eNB to perform a secure boot. For more information on the secure boot, see LTE940: SW Verification Agent.

Note: This feature provides full backwards compatibility with older (unsigned) software releases. If a user installs a software package without a signature (for example, a software downgrade to an older release), the eNB continues to download the software but generates the Unsigned software release has been successfully downloaded fault. If it is a download without activation, the unsigned software build is only downloaded to a passive file system, and the previous build is still used. If it is downloaded with activation after a BTS reset, the new, downloaded, unsigned software build is used.

Additional hardware requirements This feature requires no new or additional hardware. Functional description Functional overview A drive test (DT) is a manual method which allows the operator to gather information about the network in a particular area. Such parameters as the radio signal quality, signaling events or throughput are measured from the field and recorded by dedicated equipment. There are many expensive tools used for drive tests. To have detailed information about network behavior, operators should perform DTs periodically for the whole coverage area, due to constantly changing network traffic conditions and the consequent need for optimization activities. Using such an approach is costly for operators. A minimization of drive tests (MDT) has been proposed in order to meet operator requirements. It is a method of collecting the DT data directly from regular UEs used in the network; it is a less expensive approach to DTs. There are two modes of MDT measurements:

Descriptions of operability features
logged MDT immediate MDT
The LTE1049: MDT – UE Measurement Logs feature is focused only on the logged MDT measurements mode. The logged MDT is a mode where the UE is able to collect measurements during RRC IDLE state and store them for up to 48 hours. However, the configuration parameters for the logged MDT mode and the logged MDT measurement reports shall be sent when the UE is in the RRC CONNECTED state. There are two independent the logged MDT initiation scenarios : •
•
signaling - based activation (SBA) - the operator initiates a subscriber-specific trace session in NetAct or a third-party tool by issuing an MDT trace session activation message towards the core network (CN); it is not in the scope of the feature. management - based activation (MBA) - the operator initiates an area-based trace session in NetAct, TraceViewer, or the BTSSM by issuing an MDT trace session activation message towards an eNodeB.
The operator initiates an area-based trace session in NetAct, TraceViewer, or the BTSSM by issuing an MDT trace session activation message towards an eNodeB. The eNodeB has stored the information that the UE is allowed to perform MDT measurements in RRC IDLE state. After receiving the MDT trace session activation message, the eNodeB starts selecting capable UEs, based on the parameters, and sends them the configuration. When Logged MDT trace session starts, and the UE is in RRC CONNECTED state, it is capable of obtaining the configuration message. Only when the UE is in RRC IDLE state, it is collecting the required measurements and storing them in internal memory. When the UE comes back into RRC CONNECTED state it is able to send collected logs toward the eNodeB. If operator wants to use UE consent functionality, he needs to ensure that relevant information is stored in home subscriber server (HSS). Anonymization of data sent to Trace Collection Entity (TCE) is possible for MBA Logged MDT. The UE measurement logs contain the following information: • • • • •
location info (global navigation satellite system (GNSS) information is optional for the UE) time stamp serving cell ID serving cell measurements neighbor cell measurements
Measurements configuration The MDT measurement configuration procedure for the logged MDT is unidirectional; it is sent to the UE by the RRC signaling procedure. The logged MDT measurement reports are linked to the original logged MDT configuration. It means that any new logged MDT measurement configuration will wipe out any logged MDT measurements obtained with a corresponding previous configuration. Therefore, before sending a new LoggedMeasurementConfiguration message, the eNodeB will obtain collected measurements from the UE. This is to avoid losing any MDT data already stored in the UE.

Report retrieval The collected MDT measurements will be requested from eNodeB via UEInformationRequest message and delivered from UE to eNodeB via UEInformationResponse message. The data are normally retrieved in the cell where the availability is signaled. But the data which are retrieved need not to be from the cell where the availability is signaled. The data of the UE logs might be sent in multiple RRC signaling messages.

5.4 LTE1052: Transport Configuration Fallback 5.4.1 Description of LTE1052: Transport Configuration Fallback Introduction to the feature The LTE1052: Transport Configuration Fallback feature reverts the former working configuration of the base transceiver station (BTS) and informs the operator about the failed configuration update when the BTS fails to connect to its management network after a configuration update. Benefits End-user benefits This feature does not affect the end-user experience. Operator benefits A self-healing measure reduces the effort on network management and maintenance by avoiding site visits and increases the availability of the network because of less outages.

Additional hardware requirements This feature requires no new or additional hardware. Functional description Functional overview When the BTS fails to connect to its management network after a transport configuration update via a full site configuration file (SCF) or a delta SCF, self-healing measures are applied. A self-healing measure automatically activates the previous transport configuration when the BTS fails to connect to its management network. The LTE1052: Transport Configuration Fall-back feature is controlled via a configuration parameter (activation flag). The self-healing measure is initiated only for transport network layer (TNL) configuration changes. The TNL configuration refers to transport parameters. When the configuration changes that contain transport and non-transport changes are initiated and the BTS fails to connect to its management network, self-healing measure is only applied to the transport portion of the configuration changes, that is, only the previous transport configuration is activated and the non-transport configuration changes are not reverted.

In scenarios where both integrated operation mediation system (iOMS) resiliency and transport configuration fallback are configured, the autonomous fallback to the previous configuration shall be attempted only after iOMS resiliency is activated and did not fix the management plane (M-plane) problem. When the M-plane is established with the previous configuration, an alarm notification is sent to the network management system, which indicates that the new configuration is not activated. If the previous configuration fails, the received new configuration is activated again and the BTS continues with the regular link failure mechanism. This feature does not ensure the full eNB function in all circumstances, but the M-plane connection to the eNB is re-established in case that the failure was on a wrong transport parameter setting.

Afterwards, the eNB continues auto-connection and connects automatically to the OMS/NetAct for auto-configuration. The NetAct auto-configuration workflow is not influenced. Mandatory configurable parameters: • • • •
IP address of the eNB/management plane subnet mask of the eNB/management plane gateway for the eNB/management plane IP address of the identification server (hosted by an OMS)
Optional configurable parameters: • • • •
the IP address of the certificate authority (CA) server (CMP directory server, or registration authority server) port number of the CA server subject name for the CA server CMP directory (URL) on the CA server (mandatory if an IP address of the CA server is configured and the default directory for the HTTP access is different from http: // IPaddress: port/pkix/)
IPsec: IP address of the security gateway - if configured. The eNB will setup the O&M connection within an IPsec tunnel. Plug and Play Ethernet VLAN: This VLAN ID is used by the eNB to connect to the access network for the autoconfiguration. If not given, the eNB uses untagged Ethernet frames.
g
Note: The usage of the transport layer security protocol (TLS) for PnP is not directly configurable. If the public key infrastructure (PKI) turns out to be configured, the eNB will try to set up a secure TLS connection to the OAM system in the probing mode. If the secure setup fails, the eNB will continue PnP in an unsecure mode. Reset a BTS to “not commissioned” In case of any problems, it is possible to reset a BTS with a local connected BTS site manager to “not commissioned”, thus forcing the BTS to run the complete Plug and Play sequence again or to run a manual commissioning sequence. For the repeated PnP auto-connection phase, the BTS uses the previously configured BTS ID to identify against the identification server or a new one, in case the field engineer entered a new BTS ID. In case of a reset due to BTS relocation, typically a new and unique BTS identifier will be used for a new site (and entered by the field engineer).
g
Note: In case the BTS shall be relocated to another site and the Flexi System Module serial number is used as unique BTS identifier on the NetAct side, special attention is required. The existing configuration plan file needs to be substituted by a new initial plan file before the Flexi System Module starts Plug and Play. Otherwise, for example, the RNW parameters of the old site will be applied to the new site. The identification server and NetAct auto-configuration workflow are enhanced to allow multiple repeated PnP sequences by the same eNB.

The management-user can choose between two options: 1. Without deleting of the operator security credentials such as the operator certificate, trust anchors, and the local operator user ID and password - this is the default setting. When PnP is subsequently restarted, no new initial key signing request for a new operator entity certificate is sent. 2. With deleting of the operator security credentials. For example, the operator certificate is deleted, the vendor certificate is restored, the local maintenance user account and service user accounts are reset to factory defaults. When PnP is subsequently restarted, a new initial key signing request for a new operator entity certificate is sent, providing the case an operator's PKI is in place. The execution of the command needs to be double confirmed and is logged in the user's log file. Plug and Play Report While auto-connection and auto-configuration are running, important events and the status, which are required to analyze problems, are logged in the Plug and Play report by the BTS. The log contains in a human readable form: • • • • • • • • • • • •
all steps of workflow with results the status and the results of the workflow sub-steps the connection-setup to PKI (if used) the messages (essential parts) sent and received to/from PKI such as the initial request and result (if used) the connection-setup to OMS the messages sent and received to/from OMS such as the connection established indication with a response the identification information and all parameters received from BTSSM, if any the status of NE before the auto-connection starts which includes such information as the certificate name and SW build version the timestamp in all logged messages; note that the time of day (ToD) is not available while auto-connection is running; typically, the relative time is logged details of external messages and replies to the DHCP server, CA server, identification server (IS), OMS and BTSSM IPSec with internet key exchange (IKE) version in case of exceptions, the cause of negative result is included
Plug and Play Report upload by the iSON manager As soon as iSON is informed about the completion of the eNB auto-configuration, it uploads the eNB Plug and Play report. First the report is uploaded from the eNB to the NetAct global file system and second the iSON manager fetches the plug and play report from there. iSON stores the report file in the automatic site creation (ASC) disk area and indicates the plug and play report existence in the ASC Site user interface (UI) to the user.

Note: the iSON manager shows the hyperlink to the plug and play report file in the site UI as soon as the plug and play report is available. On user request, the iSON manager visualizes the complete human readable PnP report.

The use case describes the upload of the auto-configuration report to the iSON manager. The upload is triggered as soon as the auto-configuration is completed and the PnP report file is successfully uploaded to the NetAct file system. Pre-conditions: • • • • • •
Auto-connection has been performed with success. The M-plane connection eNB – iOMS – NetAct is setup. The auto-configuration is finished. The NetAct CM has marked the auto-configuration status according to its result. The PnP report file is uploaded to the NetAct file system. The iSON manager has registered to the auto-configuration status.
Description: 1. iSON is informed about the auto-configuration state (completed/failed) by the status update notification (iSON is registered to the auto configuration status maintained by the NetAct CM). 2. iSON sets up a timer to allow eNB, iOMS and NWI3 mediation to upload the PnP report file to the NetAct file system after the auto-configuration is finished. 3. After the timer expiry, iSON triggers the upload of the PnP report file to the automatic site creation (ASC) disk area that is dedicated for that purpose. 4. iSON indicates the existence of the PnP report to the user in the ASC Site UI (hyperlink to PnP report is shown). 5. On user request iSON visualizes the complete human readable PnP report. Post-conditions: • • •
The auto-configuration report is uploaded to the ASC and stored in the dedicated ASC repository. The auto-configuration report existence is indicated in ASC Site UI. On request the auto-configuration report is visualized to the user.

FDD-LTE15A, Feature Descriptions and Instructions
The LTE1103: Load Based Power Saving for Multi-layer Networks feature allows the operator to save energy during low-load periods. The load-based power saving is limited to the resources within a single evolved node B (eNB). The power saving mode (PWSM) allows the operator to use the LTE1103: Load Based Power Saving for Multi-layer Networks feature according to cell configuration and power amplifier mapping. The cells in the eNB can be grouped for PWSM. These power group cells have the same coverage and the Load-based power saving cell switch off order (lbpsCellSOOrder) parameter defines the order in which the power group cells are switched off. The eNB monitors the load in the served cells and triggers cell switch off once all of the following conditions are met: During the time of the day defined by the user for cell switch off. There are no ongoing emergency calls and no queued messages for Earthquake and Tsunami Warning System (ETWS) or Commercial Mobile Alert System (CMAS) in the cell. The complete load of the cells in the power saving group is below the low load threshold. The estimated complete load immediately after cell switch off for the remaining active cells in the power saving group does not exceed the high load threshold.
• •
• •
g
Note: The eNB will not switch off a power group cell and will switch on a cell in energy saving mode if fault 7651 BTS degraded is raised on the eNB or if the cell has any of the following faults: • •
7653 Cell faulty 7654 Cell operations degraded
Similar to the LTE914: Graceful Cell Shutdown feature, the LTE1103: Load Based Power Saving for Multi-layer Networks feature gradually reduces cell power so that the active calls are handed over before cell switch off. The cell is barred before it is switched off in the eNB. The traffic is moved to other cells during cell switch off. The eNB turns the power amplifier to standby mode.
g g
Note: Switching off of all cells in the eNB is possible for special cases such as indoor office environment with macro cell coverage from another eNB. The cell is activated at a defined time of the day. Note: If a cell is beginning to switch off and the operator wants to revert the cell to full power, perform the following steps: 1. Set the Load-Based Power Saving Suspended (lbpsSuspended) PSGRP parameter value to true and the Administrative state (administrativeState) LNCEL parameter value to locked. This completes the cell switch off that must be done before switching on the cell. All other power saving group cells with administrativeState LNCEL parameter set to unlocked will have services enabled. 2. Set the administrativeState LNCEL parameter value to unlocked to enable services in the cell.

The eNB continues to monitor the load on the active cells after the cell switch off. A cell that was switched off can be activated if the total traffic load of the active cells in the power saving group exceeds the user-defined high traffic threshold. The LTE1103: Load Based Power Saving for Multi-layer Networks feature does not require the exchange of X2 data between Flexi Multiradio BTSs. It is recommended to first switch off the higher frequency layer.

•
•
•
LTE1117: LTE MBMS A cell configured to support multimedia broadcast/multicast service (MBMS) cannot participate in load-based power saving. Energy saving must not be configured to switch off a cell that is configured for MBMS. LTE432: Cell Outage Detection Cell outage detection is not triggered for a cell in energy saving state (energySavingState parameter = 1). LTE494: Commercial Mobile Alert System Energy saving must not be configured to switch off the last enabled cell in the power saving group configured to provide CMAS service. Also, a cell is not set to energy saving state if there are queued CMAS messages. LTE843: ETWS Broadcast Energy saving must not be configured to switch off the last enabled cell in the power saving group that is configured with the LTE843: ETWS Broadcast feature. Also, a cell cannot be set to energy saving state if there are queued ETWS messages. LTE1685: Neighbor Relation Robustness Existing neighbor relations do not change when a cell is in energy saving state. The neighbor cells become available when the cell is restored. LTE495: OTDOA Energy saving is not allowed to switch off the last enabled cell in the power saving group that is configured with the LTE495: OTDOA feature. LTE1542: FDD Supercell The creation of power saving groups must recognize that a super cell is treated as a single cell that has two sub-cells, which serve the same area. enhanced inter-cell interference coordination (eICIC) features: – –

This reduces the probability that LB will be used to balance the load across the active cells while there are disabled power group cells because of energy saving. radio frequency (RF) sharing features: – – –
LTE435: RF Sharing WCDMA-LTE LTE1556: 3-RAT RF Sharing 2G-3G and 2G-4G LTE1829: LTE-LTE RF sharing
It is recommended that energy saving is not configured for cells in the power saving group that support RF sharing. Impact on interfaces The load on the S1 interface is the same or less when the operator initiates the cell shutdown. Impact on network management tools An integrated self-organizing network (iSON) manager application can be used to create and update the power saving groups at the selected set of eNBs. Impact on system performance and capacity The overall capacity of each power saving group is reduced to only what is needed by the UEs in the system.

Additional hardware requirements This feature requires no new or additional hardware. Functional description Functional overview The antenna line devices (ALDs) require periodic software updates since new features and bug fixes are provided by ALD vendors. Without the LTE1227: Flexi Multiradio BTS SW Download for Antenna Line Devices feature, the ALD software update requires both an ALD service interruption (to facilitate communication with the ALD hardware) and a site visit. A tower crew might be required depending on how the ALD equipment is installed at the site. The LTE1227: Flexi Multiradio BTS SW Download for Antenna Line Devices feature introduces the capability for an operator to remotely (from a Nokia management station) update the ALD software on either of the following management stations: • •
NetAct software manager application BTSSM application
The ALD software update requires that the ALD software is packaged according to Nokia software packaging standards. An ALD software update-specific build descriptor is created, which classifies the software elements in a software package. The operator is responsible for obtaining the ALD software image associated with the ALD hardware that is installed at each site. The operator is also responsible for packaging the ALD software image with an appropriate build descriptor. To help the operator in doing this, the LTE1227: Flexi Multiradio BTS SW Download for Antenna Line Devices feature provides a BTSSM application that assists the operator in creating an appropriate ALD software update-specific build descriptor. The operator zips this build descriptor with the ALD software image to create an ALD software package that is ready for staging and distribution. When the ALD software is properly packaged, the operator stages the ALD software either on NetAct or BTSSM. This is achieved by using the existing software staging mechanisms that are available on NetAct and BTSSM. The LTE1227: Flexi Multiradio BTS SW Download for Antenna Line Devices feature does not change the existing software staging interface. The operator starts the ALD software update procedure when the staging is done. The ALD software update procedure is achieved by using the existing software download and activation interfaces that are provided by NetAct and BTSSM. The LTE1227: Flexi Multiradio BTS SW Download for Antenna Line Devices feature does not change the existing software management user interfaces, nor the software management interfaces between the management stations and the evolved Node B (eNB).

Descriptions of operability features
The ALD software update occurs only when both download and activation are specified by the operator. The download and activation of ALD software occur only when the operator initiates the download with automatic activation operation at one of the management stations. If the operator invokes the "download only" option of the software update, it has no effect on the ALD. The eNB simply indicates that the download is successful without performing any software update on the ALD. When the software download with automatic activation operation is initiated, the eNB downloads the ALD software package from the management station that is recognized based on the build descriptor. The software download with automatic activation operation indicates that an ALD software update is being requested. The ALD software image is downloaded and activated to each affected ALD device. After the ALD software image is activated to each affected ALD device, the downloaded ALD software package is removed from the eNB. Finally, the eNB informs the operator if the ALD software update operation is successful or not. When the ALD software update operation is successful, the ALD's site configuration file (SCF) data is updated with the new software version in each successfully updated ALD.
g g
Note: All the ALD instances of a given type or vendor, as specified in the ALD-specific build descriptor, are updated via this procedure. It is not possible to update selected instances of ALDs. Note: The ALD resets autonomously after the new software is downloaded. System impact Interdependencies between features There are no interdependencies between this and any other feature. Impact on interfaces This feature has no impact on interfaces. Impact on network management tools This feature has no impact on network management tools. Impact on system performance and capacity The impact of the LTE1227: Flexi Multiradio BTS SW Download for Antenna Line Devices feature on RAN-level system performance and capacity is minimal because the ALD software update is performed typically during a maintenance window.

Note: This feature is only applicable to the FSMr3 BTS and the Flexi Zone Micro. Additional hardware requirements This feature requires no new or additional hardware. Functional description Functional overview Collecting syslog data in local log files by the BTS allows identifying software and hardware issues and any other unidentified misbehavior of the BTS. The syslog data is analyzed by Nokia Technical Support experts. Due to a limited size of such log files, data may get overwritten and therefore is unavailable to Technical Support for fault diagnosis. In order to avoid such situations, the LTE1408: Remote Syslog for Continuous Log Storage feature provides a remote continuous syslog storage solution. This enables to continuously push syslogs in real time from the BTS to the remote syslog server and overcome the disadvantages of locally stored log files. Syslog IP packets are transmitted with a BTS M-plane IP address as a source IP address and with a remote syslog server IP address (configured during commissioning) as a destination IP address.
g
Note: In order to ensure the usability of LTE1408, it is necessary to increase the Mplane link capacity as the average throughput of remote syslog data is 10 Mbps (with 25 Mbps of peak values). Syslog server The remote syslog server is a platform owned by the operator. In emergency situations, when a maximum of five BTSs need diagnosis, the iOMS can serve as the remote syslog server. Some operators may already have a remote syslog server in their networks as this feature is already supported by many switches and routers (for example Cisco). An iOMS allows storing at least 50 GB of remote syslog data. Such capacity is enough to store from about 1 to 2 hours of syslog data from five BTSs. Increasing the maximum accepted number of TLS connections or configuring more UDP syslog clients will decrease the feature's usability and may cause some stability issues in iOMS.
g
Note: In case of an iOMS switchover, the syslog server address (iOMS IP address) has to be changed manually during commissioning so that the BTS can send the syslogs to the new serving iOMS. Syslog format

Descriptions of operability features
FDD-LTE15A, Feature Descriptions and Instructions
The syslog protocol format is by default RFC 5424; hence, the syslog server has to be compliant with RFC 5424. It is also possible to choose a Nokia proprietary format for the remote syslog transmission, but this proprietary format requires a dedicated Nokia application (Rsyslog for Linux or pyRemoteLogServer or Rsyslog + Rsyslog Windows Agent for Windows) to be available on the remote server to accept such syslogs from the BTS. Syslog transmision Either the User Datagram Protocol (UDP) or Transport Layer Security Protocol (TLS) can be used as the remote syslog transport layer protocol. Transport Layer Security Protocol While establishing the TLS, both iOMS and BTS need certificates in order to authenticate each other. Certificate generation is the operator’s responsibility. Certificates can be signed by a Customer certificate authority (CA). Customer CA shall be also used to sign the TLS certificates on the operator’s remote syslog server. It is recommended to use the TLS protocol when a reliable connection with no data loss is essential.
g
Note: When the TLS protocol is configured for a remote syslog, the TLS connection will not automatically reconnect after a recovery of an Ethernet link outage. When the TLS protocol is configured for a remote syslog, the TLS remote syslog connection between a BTS and syslog server should start only after a server is up and running. User Datagram Protocol In a UDP configuration, the UDP does not re-send data in case of packet losses. When no reserved bandwidth is available for syslog traffic, it is recommended to use a higher DSCP value to avoid a loss of packets. Alternatively, the syslogs can be sent securely to the remote syslog server, using a UDP in an IPsec tunnel. If network security is not a concern, a UDP without any kind of encryption (that is, no IPsec) may be used. It is recommended to use the UDP protocol in a situation where an Ethernet link is not stable and a minor data loss is permissible.
g
Note: It is recommended to configure the M-plane traffic with a higher priority as compared to the tracing and syslog traffic. Tracing and syslog may generate a significant traffic volume in the uplink, which could otherwise negatively affect more important O&M operations. Supported file transfer protocols (configurable by the operator) for syslog traffic (see also Table 3): • •

The LTE1434: Flexi Multiradio BTS Antenna Rx RF-sniffing feature enables a Flexi Multiradio BTS to monitor the spectrum in order to detect radio frequency interference (RFI) and radio disturbance in the peripheral radio frequency (RF) path. Benefits End-user benefits This feature does not affect the end-user experience. Operator benefits This feature provides a toolset which enables testing the BTS for RFI remotely, which reduces the customer's reliance on expensive drive tests. It contributes positively to lowering OPEX. Requirements Hardware and software requirements Table 209: Hardware and software requirements presents hardware and software requirements. Table 209

Additional software requirements This feature, in addition to BTS Site Manager software, requires installation of free Matlab Compiler Runtime (MCR) for release R2015a (can be downloaded from http://www.mathworks.com/products/compiler/mcr/). Functional description The LTE1434: Flexi Multiradio BTS Antenna Rx RF-sniffing feature enables the operator to perform an RF scan (also known as RFI snapshot or RF-intercept) and passive intermodulation (PIM) tests via the BTS Site Manager (BTSSM). This feature introduces new tests, including the RF-scan and PIM. On-line tests can be run without putting the BTS in a test mode. Off-line tests do require putting the BTS in a test mode and are service impacting. The data collected by the BTS will automatically be uploaded to the BTS Site Manager. An RF-scan and PIM data viewing application is integrated into the BTS Site Manager to provide visualization of the captured data.

FDD-LTE15A, Feature Descriptions and Instructions
The on-line tests are: 1. RF scan - collects a snapshot of the RF data received from the base station antenna in uplink. The received RF data can be depicted for the user in the form of frequency spectrum and spectrogram. 2. PIM simulation - it does not require putting the base station into a test mode since the tests involve calculations of potential interference based on the BTS's radio configuration and not actual measurements. The goal of this test is to familiarize the operator with PIM tests. The off-line test is PIM desensitization - the goal of the desensitization test is to verify if the cell configuration is causing uplink (UL) desensitization. RFI is a common hazard for network operators. The RF-scan test provided with this feature allows the operator to remotely retrieve a sample of RF data for an RFI analysis. RFI issues are difficult to diagnose. Detecting RFI typically requires a: • •
BTSSM basic site - visit - a portable spectrum analyzer is typically connected to the antenna, and the band is scanned for interferers drive test - a vehicle equipped with an antenna and a spectrum analyzer is used to drive and scan the band
Site visits and drive tests require: many hours or even days to be performed, human involvement (they cannot be automated), professional experts (technicians or engineers), and additional costs included. RF scan RF scan captures the current signal within the cell receive band. This data can be analyzed for anomalous and peculiar waveforms and radio frequency interference. This interference could be caused by environmental conditions, other high frequency transmitters, or the BTS itself (for example PIM). RF scan collects a snapshot of RF data from the Rx channel. PIM PIM is a special type of RFI, occuring in multi-carrier sites when two or more high power signals encounter non-linear junctions or materials in the RF path produce resonant frequencies (IM values). Resonant frequencies appearing in the receive band increase the floor noise and may degrade a site's capacity. PIM is a hazard for BTSs in a multi-carrier configuration where two or more carrier signals share a single antenna. PIM distortion refers to spurious signals generated when multiple high power frequencies are passed through "passive" components (connectors, cables, antenna). In a multi-carrier BTS, these spurious signals are almost guaranteed to occur; however, they are only a problem when they appear in the Rx band. The PIM tests (PIM desensitization and PIM simulation) give the operator the ability to test a BTS for PIM remotely.
g
Note: Thanks to this feature, the RF-scan and PIM test results data can be analyzed and visualized locally within the BTSSM. RF-scan results are stored in the hierarchical data format.The operator will be able to store the data files with test results for later processing and viewing. User scenarios for RF interference There are three user scenarios for when RF interference testing could be executed:

FDD-LTE15A, Feature Descriptions and Instructions
Descriptions of operability features
1. post installation sanity check - RF scan and PIM tests are triggered manually by an operator typically after installation/commissioning of a new site in order to ensure that there is no internal and external interference. 2. investigation of UL performance degradation - RF scan and PIM tests are triggered manually in cases where UL performance is degraded or degrading slowly over time, measured via ongoing performance measurements. In this case the operator may trigger an RF scan for a certain cell/sector if certain UL-related key performance indicators (KPI) are worse or worsening over time. Internal or external interference can be deduced from the collected data. 3. remote analysis of RF scan and PIM data - RF scan and PIM tests data are collected manually by an operator and exported outside of the BTS Site Manager for a remote analysis.

Main purpose of this functionality is to minimize the negative effects caused by the handover threshold not being optimally set, which results in handover failures or radio link failures. Mobility robustness optimization (MRO) Inter-RAT is based on PM counter statistics per eNB-cell and the UTRAN-target frequency layer, resulting in a long-term adaptation. Daily statistics are the basis for the evaluation of the handover performance. The PM counters are aggregated on an LTE cell for each target frequency layer. Feature Description The LTE1749: Mobility Robustness Monitoring Inter RAT feature supports both WCDMA and TD-SCDMA UTRAN networks. The feature is supported on the Flexi Macro and Flexi Zone Micro, and it is licensed on the eNB. PM counters collected by the eNB The LTE1749: Mobility Robustness Monitoring Inter RAT feature introduces a set of PM counters collected by the eNB. Table 214: New counters lists the measurements introduced with this feature. User scenarios The following user scenarios are described: User scenario 1: Activating the LTE1749: Mobility Robustness Monitoring Inter RAT feature on the eNB User scenario 2: Too Late HO when UE returns to the eNB where it had experienced RLF User scenario 3: Too Early HO when UE returns to the eNB where it had experienced handover failure User scenario 1: Activating the LTE1749: Mobility Robustness Monitoring Inter RAT feature on the eNB Pre-conditions The LTE56: Inter-RAT Handover to WCDMA or LTE898: TDD Inter-RAT Handover to TDSCDMA feature is activated on the eNB.

g
The UE encounters RLF on the LTE cell and selects a UTRAN cell to which it connects. The measurement for the selected UTRAN cell at the time of the RLF does not meet one or more of the configured B2 (for PSHO or VoLTE) thresholds. After a period of time (up to 48 hours), the UE connects or hands in to any cell on the original eNB where it had experienced RLF and indicates to the eNB that it has RLF information available. Note: The eNB where the UE finally connects to can be different from the original one where the RLF occurs. In this case, the RLF-report retrieved from the UE will be forwarded by the last accessed eNB to the original eNB via the X2 interface (if present).
• • •
The eNB retrieves the RLF-report information using the RRC-UE-Informationprocedure. Based on the information in the RLF-report, the eNB determines that it contains the cell where the UE had experienced RLF. Based on the information in the RLF-report, the eNB determines that the conditions for Too Late HO to UTRAN - {B2T2-PSHO, B2T2-VoLTE} Not Met are achieved, and it increments the appropriate counters associated with the RLF cell and the UTRAN frequency which had been selected after the RLF occurred.
Post-condition The appropriate Too Late PM counters are incremented and the original procedure (connection setup or hand-in) is completed. User scenario 3: Too Early HO when UE returns to the eNB where it had experienced handover failure Pre-condition • • • • •

Descriptions of operability features
The UE meets the B1 (for CSFB or Load Balancing) or B2 (for PSHO or VoLTE) measurement reporting conditions and sends the measurement report to the eNB. The UE encounters handover failure and re-establishes back to any cell on the same eNB on which it had experienced the failure (reestablishmentCause will be “handoverFailure” in this case). The eNB determines that it contains the cell where the UE was last connected (identified by the physCellId from the RRCConnectionReestablishmentRequest), and looks up an UE context (using the existing mechanism to find the UE context). An UE context exists which indicates handover to UTRAN is in progress. Based on information contained in the UE context, the eNB determines that the conditions for “Too Early HO to UTRAN - {B2T2-PSHO, B2T2-VoLTE} Met” are met, and it increments the appropriate counters associated with the source cell and the UTRAN frequency to which handover had been attempted.
Post-condition The appropriate Too Early PM counters are incremented and the original reestablishment procedure completes as per existing functionality. System impact Interdependencies between features The following features influence LTE1749: Mobility Robustness Monitoring Inter RAT: •

Additional hardware requirements This feature requires no new or additional hardware. Functional description The LTE1879: Additional PM Couters for Mobility Event Monitoring feature enhances a user equipment's (UE's) mobility analysis mechanism in addition to the already existing handover (HO) counters. Within the feature's scope, nine new counters will be created to monitor A2 and/or A1 event(s). The counters are pegged when the eNB receives the RRC measurement report with an A2/A1 event, which indicates that the configured reference signal received power (RSRP) or reference signal received quality (RSRQ) threshold was met and a corresponding event was triggered and sent by the UE. Reported by the UE A2/A1 events with RSRP/RSRQ values are mapped to the nearest upper or nearest lower thresholds. Those thresholds use settings of currently activated in the eNB mobility features which trigger A2/A1 events. UE capabilities, technology for which given measurement was activated and if UE has the QCI1 established or not is less essential than the value of the reported RSRP/RSRQ.

Descriptions of operability features
FDD-LTE15A, Feature Descriptions and Instructions
After the eNB upgrade, the data conversion performed by the eNB during the upgrade needs to be synchronized with the NetAct configuration manager (CM). The LTE954: Intelligent configuration synchronization feature automatically synchronizes NetAct. If the LTE954: Intelligent configuration synchronization feature is enabled, automatic upload of the configuration data is not started immediately after the upgrade, but is started after a configurable time interval. If this feature is disabled, data synchronization of NetAct must be executed manually after the upgrade via CM upload. Data management during software upgrade All operator-configured data are maintained in the system. Configuration data created in the earlier release are automatically converted into a new format valid for the new release during the upgrade. The data include the following: • • •
g
all configuration data of the Flexi Multiradio BTS, OMS, NetAct, L3DC, and Traffica customized view in the BTS site manager (BTSSM) or NetAct user specified accounts and passwords Note: In case of off-line migration in the BTSSM, there should only be less than or equal to 16 LNRELW managed objects for each carrier frequency (under LNCEL managed object) with the Redirect with system information allowed (redirWithSysInfoAllowed) parameter set to allowed.
After the system upgrade and fallback, no important NE information is lost. This information includes the following: • • • •
network security-related system data (such as certificates and keys) user security-related data (such as user accounts and passwords) symptom, trace, and log data configuration data (such as transport configuration, base transceiver station (BTS) configuration, radio network (RNW) configuration, and performance management (PM) data configuration)
Backward compatibility Backward compatibility means that interworking between the upgraded and the nonupgraded NEs is possible during the system upgrade. Because of the top-down approach, the following backward compatibilities are supported: • • • •
NetAct 15.5 needs to support the OMS and eNB with releases RL60 and RL70. LTO15A needs to support the eNB with releases RL60 and RL70. Traffica 15.5 needs to support the L3DC and eNB with releases RL60 and RL70. L3DC 15 needs to support the eNB with releases RL60 and RL70.
In addition, mixed eNB and OMS configurations such as LTO15A (FDD-LTE 15A) and LN7.0 (RL70) must be supported by the OMS and NetAct, while mixed L3DC and eNB configurations such as L3DC 15 (FDD-LTE 15A) and LN7.0 (eNB RL70) must be supported by the L3DC and Traffica.

FDD-LTE15A, Feature Descriptions and Instructions
Descriptions of operability features
The eNB SW of a new release (FDD-LTE 15A) is backward compatible with the configuration data of a former base release RL70 or RL60. After the start up, the new SW can access and read the configuration data of the former release as input for the conversion to a new format. This is necessary to support automatic online data conversion. Software fallback Software fallback is an automatic activation of an earlier SW version that is active before the SW upgrade and is stored in the eNB. Fallback is triggered when the eNB or OMS is unable to activate its new software version or use a new database configuration version. If the eNB does not locally store the complete fallback SW for all the hardware (HW) units, it may request from NetAct a software update for the latest active software build for a managed HW module compatible with the eNB software version. Only after the SW download from NetAct can service be re-established. After the successful fallback, the passive software build is active in all the HW units and service can be re-established. Any configuration updates done with the new SW is lost, since the eNB takes the configuration database into service that fits to the fallback SW.
g
Note: In case of minor failures, no SW fallback is initiated but the error information is indicated. The failures are logged in a non-volatile memory and include a detailed information about the reason of the failure. Software rollback SW rollback is a manually initiated SW fallback using the BTSSM or NetAct SWM. The operator can trigger SW rollback when key services are not activated successfully after the SW upgrade. Note that SW rollback is only guaranteed if the source SW version has not been removed or overwritten in a non-volatile storage (NVS). SW rollback is done with the SW stored in the passive file system and no SW download from the server is part of the operation. If the passive SW has been overwritten with a different SW version, the rollback to the former release is not possible.
g
Note: A software rollback to the stored SW load restores the earlier configuration. If there has been a major network reconfiguration after the upgrade, such as reconfiguring the eNB from IPv4 to IPv6 or updating operator certificates, then network connectivity issues can occur after the rollback. Reconfigurations after the SW upgrade must be evaluated before triggering SW rollback to avoid service outage. Software rollback introduced in RL70 is considered more reliable than software downgrade used in earlier releases. This is because in software rollback the file systems are switched and the original configuration files are used while in software downgrade the current configuration files are copied from the active to the passive bank. Software rollback for a single eNB or for eNBs in bulk can be done using the NetAct SWM. For more information, see the Software Manager Help document under Network Administration in NetAct Operating Documentation. Software rollback for a single eNB can also be performed using the Rollback to Passive SW function in the Update SW to BTS Site window on the BTSSM. If the operator selects a software version lower than the active file in the Update SW to BTS Site window on the BTSSM and clicks Update, a software downgrade occurs.
g
Issue: 01D
Note: Software downgrade should not be executed. Software downgrade to an earlier software version is not guaranteed and might end up in an uncommissioned state of the eNB.

In addition, it is possible to exclude a certain UTRAN neighbor relation from autonomous removal via a suitable operation and maintenance (O&M) configuration. revalidation of UTRAN PCI The eNB supports the checking of the validity of a stored UTRAN neighbor relations by repeating the corresponding cell global identification (CGI) measurement. The following two mechanisms trigger revalidation: –
–
•
g
FDD-LTE15A, Feature Descriptions and Instructions
If the configurable number of consecutive failures of mobility management procedures is observed for a UTRAN neighbor relation, then the eNB suspects that the UTRAN neighbor relation might be no longer correct and triggers a revalidation of the UTRAN neighbor relation. If the operator configures the periodic revalidation, the eNB periodically revalidates all the available UTRAN neighbor relations.
warning for UTRAN PCI's suspects on PCI confusion The eNB uses the UTRAN PCI revalidation process to check if there are PCIs available, which are suspects for PCI confusion. An UTRAN PCI is considered as suspect of PCI confusion if the eNB observes that the UTRAN neighbor relation stored for that UTRAN PCI, toggles between two UTRAN neighbor cells. If the PCI confusion is detected, the eNB raises a PCI confusion warning to the operator. Note: This mechanism does not solve PCI confusions, but the operator can detect this situation and take corresponding actions (for example, modifying of PCI assignments).
System impact Interdependencies between features This feature affects the following features: •

410
LTE908: ANR Inter-RAT UTRAN - Fully UE-based PCI revalidation and PCI confusion detection for UTRAN neighbor cells, as described in the LTE2062: Inter-RAT UTRAN Neighbor Relation Robustness feature, are possible only if UE-based UTRAN ANR is available for the respective UTRAN neighbor cells (CGI measurements for the UTRAN neighbor cells are possible). LTE1073: Measurement-based Redirect to UTRAN Autonomous removal mechanism for UTRAN neighbor relations will take into account triggers for measurement-based redirection to the UTRAN as one of the events that may inhibit removal of a UTRAN neighbor relation. LTE1357: LTE-UTRAN Load Balancing Autonomous removal mechanism for UTRAN neighbor relations will take into account triggers for LTE-UTRAN load balancing (that is, respective B1 measurement report) as one of the events that may inhibit the removal of a UTRAN neighbor relation. LTE507: InterRAT Neighbor Relation Optimization (LTE, UTRAN, GERAN) With the LTE507: InterRAT Neighbor Relation Optimization (LTE, UTRAN, GERAN) feature, the intelligent self-organizing network (iSON) manager evaluates performance measurements use to identify badly performing UTRAN neighbor relations. Once bad UTRAN neighbor relations have been identified, the iSON manager blacklists the respective mobility management procedures of the neighbor relation by using the respective parameters (those are, PS handover allowed (psHoAllowed), Single radio Voice call continuity allowed (srvccAllowed), and Circuit-switched fallback with PS handover allowed (csfbPsHoAllowed) parameters).

If LTE2062: Inter-RAT UTRAN Neighbor Relation Robustness feature deletes a blacklisted UTRAN neighbor relation or LNRELW, the ANR may recreate the UtranNR or LNRELW as 'not blacklisted' again, that is LTE2062: Inter-RAT UTRAN Neighbor Relation Robustness feature may remove the blacklisting performed by LTE507: InterRAT Neighbor Relation Optimization (LTE, UTRAN, GERAN) feature again. To prevent this, LTE507: InterRAT Neighbor Relation Optimization (LTE, UTRAN, GERAN) feature is enhanced to set the Remove allowed (removeAllowed) parameter to 'false' by default. The operator shall have the option to override this new behavior of the LTE507: InterRAT Neighbor Relation Optimization (LTE, UTRAN, GERAN) feature on the user interface (UI) of the iSON manager. LTE783: ANR InterRAT UTRAN With the LTE783:ANR InterRAT UTRAN feature, the iSON manager might create UTRAN neighbor relations, for example, based on geo-location data. If the LTE783:ANR InterRAT UTRAN feature is applied to create WCDMA UTRAN neighbor relations or LNRELW objects, the LTE2062: Inter-RAT UTRAN Neighbor Relation Robustness feature might autonomously remove these UTRAN neighbor relations. To prevent this, the LTE783: ANR InterRAT UTRAN feature is enhanced to set the Remove allowed (removeAllowed) parameter to 'false' by default.

5.20.2 Activating and configuring LTE2062: Inter-RAT UTRAN Neighbor Relation Robustness Before you start The LTE908: ANR Inter-RAT UTRAN - Fully UE Based feature needs to be activated to enable the PCI re-validation and the confusion detection. The Activate autonomous removal of UTRAN neighbours (actAutoUtranNeighRemoval) parameter is used for activation of the autonomous removal function. Modification of this parameter requires neither eNB restart nor cell locking.

UE's rank indication, where times of RANK1/RANK2/RANK3/RANK4 are reported by a UE for DL scheduling during a periodic measurement report interval.This measurement data is used to analyze the rationality of the double-current shedule, related to the times of downlink double-current schedules/ the number of TB blocks calculated by the network management. PRB numbers scheduled for PUSCH is defined as the PRB number actually occupied by the UE's PUSCH. This measurement data represents the original measured value of the PRB number occupied by the UE's PUSCH of the serving cell. If in this sampling the UE has not been scheduled, then the value of PUSCHPRBNum is 0.

PRB number scheduled for PDSCH is defined as the PRB number actually occupied by the UE's PDSCH. This measurement data represents the original measured value of the PRB number occupied by the UE's PDSCH of the serving cell. If in this sampling the UE has not been scheduled, then the value of PDSCHPRBNum is 0. UE's BSR reflects the number of serving cells the UE needs for an uplink data transmission. It can be used to judge whether the slow uplink rate is caused by a small buffer data volume. This measurement data represents the original measured value of a UE buffer status report received in a serving cell.
Note: All measurements are of an average value during the measurement interval. These additional measurements have the same measurement intervals (reportInterval); the report amount can be set to any valid value (2, 4, 8, 16, 32, 64, or infinity, with the default set to infinity). The ms5120, ms10240 and longer (any valid value greater than or equal to 5120 ms can be configured: 5120 ms, 10240 ms, 1 min, 6 min, 12 min, 30 min or 60 min as reportInterval). The above measurement items can be activated or deactivated by the O&M separately. The configuration for the above measurements is done via TraceViewer, NetAct CM, or BTSSM.

This feature might have a minor impact on the radio access network's (RAN's) level system performance in terms of increased response times and resource usage. However, the collection/upload of these additional periodic trace data items must not negatively impact such KPIs as the RRC setup success rate, HO success rate, cell throughput, and so on. The feature is expected to result in a small increase in the trace data bandwidth. The periodic trace bandwidth increases by about 2%, and the overall total trace bandwidth increases by about 0.5%.

Note: This feature applies to both the outdoor (Flexi Zone Micro/Pico BTS) and indoor (Flexi Zone Indoor BTS) products, not to the Flexi Zone Controller architecture. The Flexi Zone BTS is pre-provisioned prior to shipment with the following operatorspecific transport information: • • • •

the FQDN(s) or the IP address(es) of the initial security gateway (required only if the operator's CA-server is only accessible through a security gateway) the FQDN(s) or the IP address(es) of the serving security gateway the FQDN(s) or IP address(es) of the initial iOMS the operator root certificate (required only if the operator's CA-server is only accessible through a security gateway). This information is required to be preserved during a reset (including config reset and factory reset). The operator has the ability to overwrite this information via the BTS Site Manager.

FDD-LTE15A, Feature Descriptions and Instructions
The initial security gateway information must be specified if the operator's CAserver is behind a security gateway. If the operator's CA-server is accessible in the public domain, the initial security gateway must NOT be specified. The serving security gateway information must ALWAYS be specified, irrespective of the location of the CA-server. The operator can set the initial security gateway differently from the serving security gateway, if the operator intends to limit the access of the BTSs creating the IPSec tunnel using the vendor certificates with the initial security gateway. If the operator does not plan to limit the access of such BTSs (or plans to use other mechanisms to limit the access, for example, white lists), the initial security gateway and the serving security gateway can be set to the same values. Both of these must still be specified if the operator's CA-server is behind a security gateway.
Note: Primary and secondary FQDNs or IP addresses: The primary and secondary FQDNs or IP addresses have been provided to allow redundancy. If the primary device is not accessible, the secondary device should be used. The Flexi Zone BTSs that do not have this information pre-provisioned at shipment follow existing Plug and Play procedures (LTE154: SON LTE BTS Auto Connectivity and LTE720: SON LTE BTS Auto Configuration).. If the Flexi Zone BTS receives appropriate information via dynamic host configuration protocol (DHCP), it utilizes the existing Plug and Play procedures. Otherwise, if the Flexi Zone BTS does not receive the necessary information via DHCP, it bypasses the existing Plug and Play procedures and utilizes the modified procedures introduced with this feature to obtain an IP address from the local DHCP server and connects to the local DNS server to resolve the operator specific fully qualified domain names (FQDN) into IP addresses and connects to the operator's transport network. If an FQDN is provided for the OMS, the security gateway provides the IP address of the operator's internal DNS via IKEv2 configuration payload in order to resolve the FQDN. If the operator's security gateway does not support this function, an IP address is provisioned for the initial OMS in the Flexi Zone BTS at the factory. Once the Flexi Zone BTS has connected to the initial OMS, the remaining autoconnection flow remains unchanged as does the auto-configuration flow.

Descriptions of operability features
If more than one FQDN (primary and secondary) is provided for the initial security gateway or if more than one IP address is returned when the FQDN of the initial security gateway is resolved by the public DNS server, the Flexi Zone BTS will use the primary one to connect. If that is not successful, the Flexi Zone BTS will use the secondary one for the connection. A similar approach is applied when connecting to the serving security gateway and the initial iOMS. Use cases The following use cases are described: Use case 1a: CA-server accessible only in operator's private network AND the "initial security gateway" and the "serving security gateway" are the same Use case 1b: CA-server is accessible only in operator's private network AND the initial security gateway and the serving security gateway are different Use case 2: Plug and play deployment of FZM in non-operator owned backhaul when CA server resides in public network Use case 3: Creation / Modification of auto-connection parameters for non-operator owned (untrusted) backhaul Use case 4: Preservation of the pre-configured operator specific transport information for a configuration reset Use case 1a: CA-server accessible only in operator's private network AND the "initial security gateway" and the "serving security gateway" are the same Figure 48

The eNB is assigned an IP address by the public/enterprise DHCP server, which also provides the public/enterprise DNS server's address(es). The eNB acquires the IP address of the initial SeGW (pre-configured on the eNB) through the public/enterprise DNS server. (This step is not required if the IP address of the initial SeGW is pre-configured on the eNB). The eNB establishes the IPSec tunnel to the initial SeGW using the vendor certificate. The eNB acquires the IP address of the certificate authority server by resolving the FQDN of the certificate authority server (pre-configured on the eNB) through the private DNS server. (This step is not required if the IP address of the certificate authority server is pre-configured on the eNB). The eNB performs the certificate enrolment and gets the operator's certificate from the CA-server. The eNB tears down the initial IPSec tunnel created using the vendor's certificate. The eNB acquires the IP address of the serving SeGW by resolving the FQDN of the SeGW (pre-configured on the eNB) through the public/enterprise DNS server. (This step is not required if the IP address of the serving SeGW is pre-configured on the eNB) The eNB establishes the IPSec tunnel to the serving SeGW using the operator certificate obtained from the CA-server. The eNB acquires the IP address of the initial iOMS by resolving the FQDN of the iOMS (pre-configured on the eNB) through the private DNS server. (This step is not required if the IP address of the initial iOMS is pre-configured on the eNB). The eNB establishes a connection to the initial iOMS. The identification server on the initial iOMS identifies the eNB based on the identification parameters (HW serial # or GPS coordinates) and provides the final iOMS address from where the eNB acquires the SW and configuration data as part of the auto-configuration.

no physical changes to the private networks no disruption to WAN traffic common VLAN for all FZAPs within an enterprise group DHCP hosting within the FZC, assigning IPs to FZAPs across different Subnets
The successful configuration of the LTE2346: Flexi Zone Controller Shared Backhaul Support - Phase I includes the following requirements: • • •
The operator manages/owns the L3 router and its configuration. All FZAPs are connected to the aggregation switch via Ethernet cabling. The L3 router must not be configured with any of these: – –
• • • •
Network Address Translation (NAT) Network Address and Port Translation (NAPT)
The FZAPs must be deployed within unique subnets across the enterprise VLANs. The use of IPSec is mandatory within the Zone deployment. The outgoing traffic from FZAP via L3 router needs to go through the FZC southbound (SB) interface. L2/L3 markings must be configured and honored by the intermediate zone devices.
System impact Interdependencies between features The following features have to be enabled before activation of the LTE2346: Flexi Zone Controller Shared Backhaul Support - Phase I: • •
LTE1996: Flexi Zone Controller Application LTE2017: IPSec Support for Flexi Zone Controller
The LTE2346 feature can be understood as an extension of the FZC Z1 backhaul capability provided in feature LTE1996. There are no features whose functionality is affected by LTE2346: Flexi Zone Controller Shared Backhaul Support - Phase I. The functionality impact of this feature is limited to the FZC. From the FZAP point of view this feature does not result in any change. Impact on interfaces This feature impacts the backhaul configuration for the Z1 interface between FZC and FZAPs. Impact on network management tools This feature has no impact on network management tools. Impact on system performance and capacity The establishment of an enterprise typically adds one or two additional hops for the L3 router and the L2 switch. There may be more hops added, depending upon the operator’s deployment environment. The additional delay introduced by those hops will have a negligible impact on the RAN level system performance.

Descriptions of operability features
The overall capacity of the FZC and its associated FZAPs is affected by the amount of bandwidth available for the Z1 backhaul. Operators are expected to deploy 10 Gbps Ethernet links. Operator deploying 1 Gbps Ethernet links will experience reduced overall throughputs for the FZAPs. Management data Alarms There are no new alarms related to this feature.

5.25.2 Activating and configuring LTE2346: Flexi Zone Controller Shared Backhaul Support - Phase I Before you start All commands supporting the LTE2346 feature are performed via the FxP’s SCLI interface. No commands can be initiated via NetAct. When the Shared Backhaul feature is enabled, the Flexi Zone Controller allows the definition of up to nine additional Enterprises. The Enterprise that is associated with the base LTE1996/LTE2203 functionality, Enterprise 0, is always present. Configuration of Enterprise 0 is outside of the scope of this document. The definition of an Enterprise includes: 1. Enterprise Name (Mandatory) The name can be up to 15 characters in length and must be unique from the other Enterprises. Enterprise 0 has the fixed name of “Base”. 2. Router IP Address (Mandatory) Enterprises must be defined with unique IP subnets that do not overlap with other IP address assignments within the FZC or for other Enterprises supported by the FZC. 3. IP Subnet Mask (Mandatory) 4. Starting IP Address of Allocation Range (Optional; defaults to first valid host IP in the IP subnet) 5. Ending IP Address of Allocation Range (Optional; defaults to last valid host IP in the IP subnet)

The Red Hat Enterprise Linux 7.1. operating system (RHEL 7.1 OS) belongs to a generation of a comprehensive suite of operating systems, designed for mission-critical enterprise computing and certified by top enterprise software and hardware vendors. The RHEL 7.1 OS offers improved development and deployment tools, enhanced interoperability and manageability, and additional security and performance features. This OS provides methods for consistent and predictable naming of network devices. Newly added features change the name of network interfaces on a system in order to make locating and differentiating of the interfaces easier. From a performance perspective, RHEL 7.1 OS supports higher processor and memory limits as well as additional features to improve the performance of applications and virtual machines, especially those running memory-intensive workloads. The LTE BTS EM SWs need to be able to run on RHEL 7.1 OS because NetAct 16.2 will not support RHEL 6.x. The support is needed for remote BTS EM sessions from NetAct. The purpose is to exploit the new features available in the newer version of the OS for the benefit of Nokia products. It should be simple and easy to enable features of the OS that can be easily exploited by the Applications. To find the installation guide for the BTS Site Manager, go to the Install and Commission, Commissioning Flexi Multiradio BTS LTE, Chapter 2 Installing BTS Site Manager document.

Support of LTE FDD multi operator network with dedicated system modules for each operator: • • •
•
•
•
Both operator's SMs (optionally equipped with extension cards) are co-located. One SM is configured as the Radio/Link Master for the shared RF modules, the other one as the Slave. Both SMs are connected by one RP3 optical link, like in RF sharing configurations (LTE447, LTE435). Beside port 6 on FSMF also one optical port on FBBA/C can be used (port 3 on FBBC). Transport interfaces for each operator are separate. They can be combined into one physical interface by LTE649 QoS aware Ethernet Switching. Operators can use their own security gateway for IPsec. Both SMs are managed by a single NetAct system. Both SMs are managed by their own dedicated BTSSM, that is, there are two BTSSMs, one per operator. There is no restriction obliging both SMs to be connected to the same iOMS although this is be the expected configuration. Each SM connects to shared radio module(s) via one (or more) optical 3 or 6 Gbit/s optical interfaces.
The Radio Units are shared between two operators: • •
•
Issue: 01D
Each shared RF unit supports one LTE carrier per sector per operator. For each operator, a dedicated spectrum and a dedicated output power is assigned (with the exception of Rel2.1 radios where only equal power levels between carriers are supported). More details about supported configurations can be found in the Creating LTE Configurations and LTE Base Stations Supported Configurations documents.

During the site visit 6
Install new FBBCs if any, new, shared RFMs/RRHs, and cabling on eNB-1. Install eNB-2's new FSMF or FSMF with one or two FBBCs, dedicated RFMs/RRH/s, antennas, and cabling. Do not connect the new SM to the already deployed SM and RFMs/RRHs. This way does not disturb the already deployed technology transmission.
7
Power up the eNB-2 SM. Update the SW, if not done before. This ensures that the new SM is running the correct SW before proceeding.
8
Power off the eNB-1 and the eNB-2 SMs and finalize the HW installation for RF Sharing. To connect the modules for RF Sharing configurations, see LTE Base Stations Supported Configurations. For details, see the respective Installing and Cabling Flexi Multiradio documentation. Ensure that the RFM/RRH has the same SFP type as the SM - 3 Gbps or 6 Gbps. It is recommended to use 6 Gbps SFPs and optical links, when supported by the used HW. Connect the eNB-2 to eNB-1 via RP3-01 optical and sync cables. Step result The eNB-1's traffic is reduced.
9
Recommended (Optional): Switch the RFM/RRH power cables to the eNB-1. The Shared RFMs/RRHs can be powered from either eNB-1 SM, eNB-2 SM, or an external power supply, depending on the site environment. If the RFMs/RRHs are powered from the eNB-2 SM and a HW reset or a failure occurs in the eNB-2 SM, both eNB' traffic is reduced. If the RFMs/RRHs are powered from the eNB-1 SM (as recommended) and a reset or failure occurs in the eNB-2 SM gets, only the eNB-2 traffic is reduced.
10 Power up the eNB-1's SM and ensure all the RFMs/RRHs and ALDs are detected and shown properly in the BTS Site Manager. If Incompatible SW version detected (0023) alarm is raised, update the SW again. Step result The HW is now ready for commissioning.

Proceed to LTE Carriers. Enter the EARFCN channel value for each Local Cell. These EARFCN values are stored in the SCF and are later used for commissioning. Select the appropriate Bandwidth. Ensure the Bandwidth is supported by the used HW configuration. For details see LTE Base Stations Supported Configurations.
g
Note: Make sure that all LTE carriers are within the RFM's/RRH's UL/DL instantaneous bandwidth, and that they are not overlapping.
f
Configuration of the same EARFCN on cells from different eNBs will cause severe performance degradation for the radio Master and for a the radio Slave simultaneously.

If both eNBs are not commissioned, the eNB that detects the shared radios first takes over the mastership and the other eNB takes the slave role. If the configuration plan download (from NetAct) fails for eNB-1 or eNB-2, the user is informed with proper error code and the new failed configuration is not taken into use (no change for current existing procedure). If shared RF parameter activation fails, the shared RF parameter is not changed and user is informed with activation feedback. The failure of eNB-1 configuration leads to the situation in which eNB-2 configuration is invalid (if it is according master configuration). If both BTSs are configured as radio master for the shared radios, the BTS that detects the shared radios first takes over the mastership and uses the shared radios. The other BTS raises alarm (Fault: Radio Master Conflict) and cannot use the shared radios. If both BTSs are configured as radio slave for the shared radios, the BTS that detects the shared radios first configures the shared radios, raises alarm (Fault: Shared radio not synchronized to Radio Master), but does not use the shared radios (as it detects the peer BTS). The other BTS takes the slave role and uses the shared radios. If the slave BTS is activated long before the configured master BTS and LTE1710B is enabled, the slave BTS issues alarm (Fault: Shared radio not synchronized to Radio Master), determines that LTE1710B is enabled, cancels alarm (Fault: Shared radio not synchronized to Radio Master), takes temporary radio mastership of the shared radios, raises alarm (Fault: Temporary Radio Master) and uses the shared radios. Once the configured master BTS is activated, it determines that the shared radios have a master and raises alarm (Fault: Radio Master Conflict). The master and slave BTSs negotiate mastership. The slave BTS releases temporary mastership, cancels alarm (Fault: Temporary Radio Master), and takes over the slave role. The configured master BTS cancels alarm (Fault: Radio Master Conflict) and takes over the master role. The shared radios are in use by both BTSs. If the slave BTS is activated before the configured master BTS and LTE1710B is disabled, the slave BTS issues alarm (Fault: Shared radio not synchronized to Radio Master) and cannot use the shared radios. Once the master BTS is activated, the

master and slave BTSs negotiate mastership. The slave BTS cancels alarm (Fault: Shared radio not synchronized to Radio Master) and takes the slave role. The master BTS takes over the master role. The shared radios are in use by both BTSs. FSM-1 notes it is connected to RF secondary port. FSM-1 receives a request from the opposite FSM-2, whether FSM-1 wants to have the mastership of this radio. FSM-1 responds 'Yes'. FSM-2 switches the RF primary opt port ownership to FSM-1. In case Ethernet was already enabled for this radio, the radio triggers a recovery reset.

6.2.3 Deactivating LTE1829: Inter eNB RF sharing Before you start The Rf sharing enabled (rfSharingEnabled) parameter is used for deactivation. Modification of this parameter does not require neither eNB restart nor cell locking. To deactivate the LTE1829: Inter eNB RF Sharing feature, do the following: Procedure 1
