Licensing Optional Software (SW) features and capacity of the WCDMA RAN are controlled by licenses. Licensing enables ‘‘Pay as you grow’’ pricing models, where the operator can balance the cost of SW capacity and features with their

219/1553-HSD10102 Uen B | 2016-05-20

11

Optional Features

customer growth. Licenses enable the operator to wait with investments until a clear need for more capacity occurs. Consequently, the operator Capital Expenditure (CAPEX) becomes better linked to the actual income. Licensing can increase SW capacity up to the installed Hardware (HW) capacity without any site visits, and new features can be activated without any new SW installation. Additional capacity and optional SW features are remotely unlocked by License Key Files (LKFs) installed through the OSS. The LKF is linked to a certain physical piece of HW by an HW ‘‘fingerprint’’. This fingerprint is the serial number of a main subrack backplane (in the radio node and the RNC). The LKF can also be linked by the Unique Logical Name. The unique logical name can be set on the node with the setUln Managed Object (MO) action of the MO Licensing. This licensing is in the radio node only. Figure 1 illustrates the distribution of licenses to the nodes. When an order is placed, a file with LKFs, one for each node, is sent. The LKFs are copied into the Software Management Organizer in OSS. The organizer stores the LKFs on a File Transfer Protocol (FTP) server and informs the nodes about their new LKFs. The nodes retrieve the LKFs from the FTP server. The control mechanism for Channel Element (CE) capacity licenses resides in the RNC. In the congestion control and admission control functions, the RNC checks the licensed Uplink (UL) and Downlink (DL) capacity keys in the radio node. The activation of optional features in the RNC and the radio node is independently controlled by each node. The RNC also has its own capacity license keys. Note:

On baseband radio nodes, the feature activation of FAJ 121 1009: Delayed Activation of Capacity Control, is default ON.

LKFs are technically mandatory in the RNC and radio nodes. Using an RNC or radio node commercially without LKFs installed is not possible.

Optional Features

2.1.15

FAJ 121 1084: TrFO Support for Speech 12.2 kbps This feature provides the RAN support for TrFO and TFO for AMR 12.2 speech. TrFO or TFO means, in a mobile-to-mobile speech call, no transcoding is needed in the CN regarding WCDMA or in the Base Station System (BSS) regarding GSM. Instead, the speech coding or decoding is done only in the sending or receiving UE. This results in a transmission savings in the backbone transmission network and also improves the speech quality, since an extra coding or decoding step can be avoided. In the TrFO case, savings are identified also by transcoder resources. This feature requires the optional RAN feature FAJ 121 146, Conversational RAB for AMR Speech 12.2. For other information, refer to Connection Handling.

2.1.16

FAJ 121 1302: Support for I/F to Positioning Center (IuPC) This is an interface providing positioning information exchange between the RNC and the Stand-Alone Serving Mobile Location Center (SAS) node. The positioning functionality is divided between the RNC and the SAS node. The SAS node decides which positioning methods to use to fulfill QoS requirements. The RNC serves as a relay between the SAS node and other nodes involved, that is the CN, radio node, and the UE. With this feature, WCDMA can benefit from using the same positioning architecture as GSM. For other information, refer to Iupc.

2.1.17

FAJ 121 1326: Cell Broadcast Service The Cell Broadcast Service (CBS) feature enables broadcast of short text messages over a FACH channel to selected UTRAN cells. The messages, including information on for instance repetition frequency and number of repetitions, are sent from a CBC to the RNC through the Iubc interface. Only the UE units in Idle Mode and in UTRAN Registration Area_Paging Channel (URA_PCH) state are able to receive messages through the CBS. This feature also enables the operator to monitor the status of a CBS message transmission. The feature requires R4 HW (or later) for the RANAP/RNSAP Main Processor (MP) in RNC. It also requires support in the terminal and the availability of a CBC. This feature also introduces the geodiversified CBC installation with dual CBC IP addresses. With this solution, the RNC is able to communicate with two different CBCs, with only one active CBC at a time.

22

219/1553-HSD10102 Uen B | 2016-05-20

WCDMA RAN Optional Features

2.2.22

FAJ 121 1496: Faster Establishment, Direct Upswitch from URA This feature improves latency rates during session setup in WRAN. Instead of a connection switching up to CELL_FACH and then CELL_DCH, an upswitch directly from URA_PCH to CELL_DCH is made. During upswitch, the repetitions of the Cell Update Confirm message on FACH can be configured for PS-initiated calls. The configured repetition time is a trade-off between FACH1 load and the success rate of the direct upswitch to CELL_DCH and both must be considered when tuning this parameter. This feature requires the optional RAN feature FAJ 121 407, UTRAN Registration Area Handling. For information about activation and deactivation, refer to Channel Switching.

2.2.23

FAJ 121 1510: Pre-coder for Power Balancing To use the radio node power efficiently when MIMO is activated in the cell, the output power needs to be balanced between the two power amplifiers. A pre-coder is implemented in the baseband to balance power when MIMO is activated or the cell is configured with two TX branches. For the configurations of two branches with different power capabilities, when the NodeBFunction::nonEqPwrCommonPrecoderState parameter is set to ACTIVATED, the total cell power is the sum of the output power of the two branches instead of based on the least capable branch. For more information, refer to HSDPA Migration and Activation.

2.2.24

FAJ 121 1552: Fast Dormancy Handling This feature is used to control whether the UE is switched to URA instead of Idle during fast dormancy signaling. Subsequent data can then be handled by an upswitch to FACH when the amount of data is lower, and to HSPA when the amount is higher. As an overall result, the signaling load is improved for chatty applications with fast dormancy that otherwise are typically switched between HSPA and Idle Mode. This feature requires the optional RAN feature FAJ 121 407: UTRAN Registration Area Handling.

36

219/1553-HSD10102 Uen B | 2016-05-20

WCDMA RAN Optional Features

For more information, refer to Connection Handling and Channel Switching.

2.2.25

FAJ 121 1581: RNC RRC Load Control The RNC RRC Load Control function prevents a single Module MP (mMP) processor overload. The feature detects the RRC admission load peak buildup in an mMP and limits the peak growth to bring the MP load back to a sustainable level. For more information, refer to RNC RRC Load Control, Capacity Management and Network Robustness and Network Load Regulation.

2.2.26

FAJ 121 1584: UL Efficiency - DCH/EUL Load Balancing This feature introduces load balancing between DCH and EUL users. EUL congestion is detected when the average rate for the EUL-connected UE units with the unhappy bit set is below a certain threshold for a specified time. The Node B Application Part (NBAP) measurement report is then sent to the RNC. The RNC initiates congestion resolving action, that is a stepwise channel switching of DCH users to lower rate, but not lower than the lowest DCH UL rate. During EUL congestion, the DCH-DCH upswitch on UL is not allowed. RAB establishment on EUL and high DCH rate attempts are rejected, but after a retry, a setup on the lowest DCH is possible. As a result, the service quality of EUL users improves. This feature requires the following RAN features: •

FAJ 121 1023: Enhanced Uplink Introduction Package

•

Having the feature FAJ 121 905: HSDPA Interactive 384/HS RAB PS (16/HS) + SRB (3.4/3.4) installed and activated is recommended, because the UL resource used by DCH needs to be low to make enough room for EUL users

For more information, refer to UL Efficiency – DCH/EUL Load Balancing, Capacity Management and Enhanced UL Scheduler.

2.2.27

FAJ 121 1593: Admission Block Redirection This feature enables redirection to other WCDMA cells or to GSM, when the original access is blocked by admission control because of the high load. When an RRC connection request is blocked by admission control, the UE can be ordered to rescan on another WCDMA frequency and try again, and an RRC request for an originating speech call can be redirected to GSM. If a speech call is blocked by admission control at RAB establishment, a directed retry to a predefined GSM cell can be ordered instead. For more information, refer to Load Sharing and Connection Handling.

219/1553-HSD10102 Uen B | 2016-05-20

37

Optional Features

2.2.28

FAJ 121 1610: CS Voice Fallback from LTE At a Mobile Originated call or at a Mobile Terminated page all active connections in LTE are released and the UE is sent UTRA Absolute Radio Frequency Number (UARFCN) information and then sent to UTRAN. The UE goes to Idle Mode and measures or camps in a suitable UTRAN cell. If a call is a Mobile Originated call, the UE initiates a CS speech call in UTRAN by using legacy procedures. With the Mobile Terminated call, the UE sends a page response through Network Access Server (NAS) signaling, to the MSC to initiate the CS speech call by using legacy procedures. UTRAN does not know that the UE arrives because of the CS Voice Fall Back. For more information, refer to Idle Mode and Common Channel Behavior.

2.2.29

FAJ 121 1611: Packet Switched Handover from LTE When the UE moves between different RATs, its active connections can be maintained through Inter-Radio Access Technology Handover (IRATHO) mechanisms. Legacy UTRAN systems support IRATHO of CS connections to and from GERAN, and mobility to and from LTE and GERAN in Idle mode. The Packet Switched Handover from LTE feature provides the mechanisms required, on the UTRAN side, to transfer one or several already established PS connections from LTE to UTRAN. Since LTE is a PS-only network, the active connections in LTE are exclusively PS RABs. Packet Switched Handover (PSHO) from LTE is based on the 3GPP specification of PSHO from LTE in TS 23.401. For more information on the feature, refer to Packet Switched Handover from LTE.

2.2.30

FAJ 121 1616: Manual-Triggered Cyclic Access Class Barring on Cell Level This feature implements manual-triggered cyclic Access Class Barring (ACB) on the cell level. Manual barring access class 0-9 in a selectable subset of all cells in the Radio Network Subsystem (RNS) is faster and simplified. Domain-specific ACB is possible for Rel-6 or later UE. The cyclic operation distributes the access attempts in time to ensure that all access classes have a time slot to access the network. This feature requires the optional RAN feature FAJ 121 1355: Manually Triggered Access Class Barring. For more information, refer to Network Robustness and Network Load Regulation.

Supported frequency bands are bands 0, 1, 2, 5, or 8. With the HSDPA Multi Carrier feature enabled, the 9-Coverage site can be configured with two DL carriers and one UL carrier. One of the two DL carriers is a DL-only carrier that only can be used as a secondary serving High-Speed Downlink Shared Channel (HS-DSCH) cell. With the solution, for multicarrier-capable UE units, the user throughput can be almost doubled in positions with good radio condition. Additional configurations are supported for Psi-Coverage sites in W16.0 and onwards. For more information, refer to PsiCoverage and Psi-Coverage Configuration.

2.2.32

FAJ 121 1785: SRB Admission Control This feature provides users, who are configured as high-priority users through the CN, with increased accessibility for new calls in high load situations. New calls that are normally blocked can then be admitted by admission control. Requests from high-priority users can still be blocked if the cell resources are used. For more information, refer to Capacity Management and SRB Admission Control.

2.2.33

FAJ 121 1880: HSDPA IFLS Capability and Priority Handling This feature provides the following improvements for HS Inter-Frequency Load Sharing (IFLS): •

FAJ 121 2096: RNC in Pool The RNC in Pool feature allows several RNCs to work in consort as a cluster. The purpose with the RNC in Pool feature is to enable large RNSs to be created and maintained. Cluster members are seen by the external nodes as a single RNC. For external nodes, the cluster members function as a single RNC with one signaling point code and a single RNC ID. In the case of a system failure or planned maintenance on one cluster member, the operator can switch the Controlling Radio Network Controller (CRNC) role for the protected set of Iub links and cells, to the other cluster member, without the need to reconfigure the radio network. This solution secures system stability through the fast switchover to the redundant Iub configuration, which is important in extreme cases. The RNC in Pool feature requires the optional feature, FAJ 121 2097: RNC Pool Cluster Size. For more information, refer to RNC in Pool.

2.2.35

FAJ 121 2097: RNC in Pool Cluster Size The RNC in Pool Cluster Size feature states the capacity of the cluster in terms of the number of cluster members. This capacity license limits the number of cluster members, however, it does not limit the traffic. This feature is directly related to the feature FAJ 121 2096: RNC in Pool and does not work without it. For more information, refer to RNC in Pool.

2.2.36

FAJ 121 2116: Device Optimized Fast Dormancy This feature enables the reconfiguration, based on IMEISV, of the UE units that trigger Rel-8 Fast Dormancy and transmits a SIGNALING CONNECTION RELEASE INDICATION with cause value ‘‘UE requested PS data session end’’ from CELL_DCH to CELL_FACH. This feature allows the switch of selected UE units from CELL_DCH to CELL_FACH instead of URA_PCH at Rel-8 Fast Dormancy and helps avoiding the crash of the selected UE units. For more information on the feature, refer to Device Optimized Fast Dormancy.

2.2.37

FAJ 121 2119: RBS MP Load Sharing This feature introduces MP load sharing of the traffic handling between DUs.

2.2.39

FAJ 121 2135: Soft Handover Parameters on Cell Level This feature allows for defining time to trigger and reporting range values for Event 1a and Event 1b on the cell level. Defining the cell parameters is optional and if they are not defined, the corresponding parameters that exist on the RNC level are used. The Soft Handover (SHO) parameters on the cell level help to tune intra-frequency mobility behavior in troublesome areas, leading to fewer dropped calls in those areas. For more information, refer to Handover and Soft Handover Parameters on Cell Level.

2.2.40

FAJ 121 2174: Release with Redirect to LTE This feature is a RAN-controlled mobility feature that enables mobility from UTRAN to Evolved UTRA (E-UTRA) for a UMTS/LTE dual-mode terminal in Active Mode. Release with redirect to LTE is built on a 3GPP Rel-8 functionality and the mechanisms used are mandatory to be supported by UE units. The Release with redirect to LTE feature gives the possibility to delay Release with Redirect (RWR) for emergency calls, to avoid the out-of-coverage state when the UE tries to move to LTE. This improves the possibility to reach the caller with a callback from the emergency center. This feature requires the RAN optional feature FAJ 121 1474: LTE Cell Reselection. If a Fast Dormancy trigger is used, FAJ 121 1552: Fast Dormancy must also be activated. For more information, refer to Release with Redirect to LTE.

2.2.41

FAJ 121 2179: RIM Support for System Information Transfer to LTE This feature introduces support for RAN Information Management (RIM) procedures that allow an eNodeB to create and maintain relationships to external UTRAN cells. This relationship is referred to as a RIM association. Once a relationship is defined in the eNodeB, it can initiate the RIM association by requesting the RNC to report changes to System Information in that UTRAN cell. The signaling for RIM between the RNC and the eNodeB is carried through the CN.

219/1553-HSD10102 Uen B | 2016-05-20

Optional Features

For more information, refer to RIM Support for System Information Transfer to LTE.

2.2.42

FAJ 121 2368: Frequency Priority at Connection Release This feature introduces support for user redirection to another frequency at RRC Connection Release. If the information element ‘‘Redirection Info’’, containing frequency information is included in RRC Connection Release, the UE is redirected to that frequency. The feature also improves Idle Mode camping, refer to Idle Mode and Common Channel Behavior for more information. This feature is enhanced with the possibility to also trigger HS IFLS to select the target frequency for the release. To enable this option, the feature depends on the legacy HS IFLS feature (FAJ 121 1467). For more information, refer to Frequency Priority at Connection Release.

2.2.43

FAJ 121 2425: Fast Dormancy for Pre-Rel-8 UEs This feature enables the reconfiguration, based on IMEISV, of certain pre-rel-8 UE units that transmit a SIGNALING CONNECTION RELEASE INDICATION to URA_PCH. This feature enables selected pre-rel-8 UE units to use Fast Dormancy with all its benefits. For more information, refer to Fast Dormancy for pre-rel-8 UEs.

2.2.44

FAJ 121 2525: Admission/Congestion Control in Shared Networks This feature facilitates fair sharing of resources in a WCDMA RAN among several operators. It uses the Capacity Management functionality to perform the congestion resolving actions by targeting connections that belong to a sharing operator using the resources in a way exceeding their configured share to the highest degree. The feature consists of three parts, introducing the following: •

An algorithm to assign the UE to a CN operator

•

Fair resource sharing in admission-triggered soft congestion

•

Fair resource sharing in the RN Congestion Control

WCDMA RAN Optional Features

2.2.45

FAJ 121 2530: Shared RAN (MOCN) Multiple PLMN Support This feature introduces the additional functionality required for MOCN-supporting UE. The basis for the new functionality is the list of multiple PLMN-IDs broadcast in system information in the coverage area of the RAN. The list contains the PLMN-IDs of the RAN sharing operators. The MOCN-supporting UE selects one PLMN-ID from the broadcast list and includes this PLMN-ID in the request to set up a signaling connection toward the CN. The RNC matches the received PLMN-ID with the configured sharing operators and establishes a signaling connection toward the matching operator. This feature requires feature FAJ 121 974: Shared RAN (MOCN), to be activated and requires support in the MSC and the SGSN. For more information, refer to Shared RAN (MOCN) multiple PLMN support.

2.2.46

FAJ 121 2551: ANR Mobility Automatic Neighbor Relations (ANR) Mobility is a Self-Organizing Network (SON) feature implemented in the Serving Radio Network Controller (SRNC). The feature decreases the load of the operator by automatically detecting, identifying, and configuring intra-frequency neighbor relations in Neighbor Cell Lists (NCLs). The feature contributes to better Active Set (AS), which improves retainability (dropped calls ratio). For more information, refer to ANR Mobility.

2.2.47

FAJ 121 2857: SRVCC for Voice and Data Single Radio Voice Call Continuity (SRVCC) enables VoIP call continuity for the UE in LTE when the LTE coverage is lost and UTRAN does not support VoIP. For SRVCC CS and PS, this feature enables the handover of the voice component together with any PS RABs. The Mobility Management Entity (MME) involves both SGSN and MSC. Coordination mechanisms in both the MME and the RNC are required. The SRVCC for Voice and Data feature can be activated in the RNC in Pool configuration, where messages sent from the CN can be randomly received by one of the cluster members. For more information, refer to SRVCC for Voice and Data.

2.2.48

FAJ 121 2883: Smartphone Retainability for Heterogeneous Networks In heterogeneous networks or under imbalance conditions, the DPCCH quality is not guaranteed at the serving cell. This is also true of the High-Speed Dedicated Physical Control Channel (HS-DPCCH) quality, as transmitted with a fixed power offset relative to the DPCCH. The HS-DPCCH quality can be poor

219/1553-HSD10102 Uen B | 2016-05-20

43

Optional Features

and cause an unnecessary Hybrid Automatic Repeat Request (HARQ) and RLC retransmissions. The Smartphone Retainability for the Heterogeneous Networks feature provides the solution by increasing the Signal-to-Interference Ratio (SIR) target in Outer Loop Power Control (OLPC) that has to be triggered by the serving cell. For more information, refer to Smartphone Retainability for Heterogeneous Networks.

2.2.49

FAJ 121 3249: Combined Cell The Combined Cell feature allows for combining up to three cells (cell carriers) served by multiple radio units or remote radio units to one cell, called a combined cell. The cell carriers can either be located indoors or outdoors. However, all the cell carriers present in the same combined cell are considered as one logical cell with the same Physical Cell Identity (PCI). For more information, refer to Combined Cell.

2.2.50

FAJ 121 3427: IRAT Offload from LTE This feature introduces improved handling of incoming CS and PS HO requests from LTE, triggered by high load in LTE. It enables the implementation of load sharing between LTE and WCDMA cells, and traffic offload from highly loaded LTE cells to less loaded WCDMA cells. For more information, refer to Inter-Radio Access Technologyand IRAT Offload from LTE.

2.2.51

FAJ 121 3520: Cell Reselection to LTE in CELL-FACH This feature provides the UE support to perform the cell reselection from WCDMA to LTE in the CELL_FACH state. This capability is supported by an LTE-capable UE from 3GPP Release 8 (optional) and 3GPP Release 11 (mandatory). An indicator ‘‘CELL_FACH Absolute Priority Measurement Indicator’’ is added to SIB19 from 3GPP Release 11. It serves as an indication to UE during Radio Access Technology (RAT) measurements selection when the absolute priority-based cell reselection is enabled. For more information, refer to Cell Reselection to LTE in CELL-FACH.

2.2.52

FAJ 121 3588: LTE Cell Reselection Dedicated Priorities This feature enables control of how individual UE units perform cell reselection to LTE by sending dedicated priorities that override the absolute priorities received by the UE on the Broadcast Channel (BCH). These dedicated priorities are used to lower the priority of LTE frequency in the UE.

44

219/1553-HSD10102 Uen B | 2016-05-20

WCDMA RAN Optional Features

Three different parts are included in the feature LTE Cell reselection dedicated priorities. They can be used either separately or together. The functionality provided by those parts requires the feature to work together with the following prerequisite features: •

FAJ 121 3637: Subscriber Based Mobility Using SPID Based on Subscriber Profile ID (SPID) values sent from CN, the LTE cell reselection can be controlled for each UE.

•

FAJ 121 974: Shared RAN (MOCN). Regarding MOCN: LTE frequencies used for cell reselection can be allowed or filtered out, based on which CN the UE has a signaling connection to.

•

FAJ 121 3427: IRAT Offload from LTE Regarding LTE offload: UE offloaded from LTE because of high load in LTE, can be prevented to perform cell reselection back to LTE during a specific time.

For more information, refer to Idle Mode and Common Channel Behavior.

2.2.53

FAJ 121 3637: Subscriber Based Mobility Using SPID This feature enables the RNC to have influence on how individual UE units perform mobility activities, like cell reselection to LTE. The feature also allows prevention of the RWR to LTE for selected UE units (for example without the LTE subscription). By defining specific SPID values for specific subscribers, modification of parameters shared by many UE units on a dedicated basis is possible. For example, absolute reselection priorities shared by every UE unit in a cell can be overridden by sending dedicated reselection priorities to selected UE units only. This feature is used to enhance the functionality of two other features: •

FAJ 121 3588: LTE Cell Reselection Dedicated Priorities, based on SPID values sent from CN, the LTE cell reselection can be controlled for each UE unit.

•

FAJ 121 2174: Release with redirect to LTE, based on the SPID values received from CN, the RWR to LTE can be prevented for each UE unit.

For more information, refer to Subscriber Based Mobility Using SPID.

2.2.54

FAJ 121 3658: UE Throughput-Based Mobility to Wi-Fi in WCDMA The feature controls mobility between Wi-Fi and WCDMA, based on end-user throughput. The user is steered to the network, Wi-Fi, or WCDMA, that currently offers the best throughput. The throughput evaluation is performed in real time for the individual user.

45

Optional Features

For more information, refer to UE Throughput-Based Mobility to Wi-Fi in WCDMA.

2.2.55

FAJ 121 3908: Narrowband Interference Rejection The Narrowband Interference Rejection (NBIR) feature enables the radio node to use a suppression method for (frequency-wise) static or slowly moving narrowband radio interferers in the spectrum dedicated to a WCDMA carrier. The suppression function uses filters in the radio unit. Once configured as active for a Radio Frequency (RF) branch, NBIR is applied to interference suppression on a WCDMA carrier that is set up on that RF-branch of the radio unit. Interference can be caused by a range of external RF equipment (TV antenna amplifiers and push-to-talk systems, for example) that do not follow regulatory requirements for the band. The feature improves performance for the WCDMA UL. It can reduce interference in the WCDMA carrier spectrum and, therefore, improve the received UL signal. This improvement helps to maintain coverage and cell throughput. The result of the NBIR feature can be improved if the function is used together with the WCDMA feature FAJ 121 1714: Interference Suppression. For more information, refer to Narrowband Interference Rejection.

2.2.56

FAJ 121 3946: Automatically Triggered Access Class Barring on Cell Level The feature Automatically Triggered Access Class Barring on Cell Level is an extension to the legacy feature FAJ 121 1616: Manual-triggered Cyclic Access Class Barring on Cell Level, where the main difference is that this new feature automatically triggers access class barring, whereas the legacy feature requires manual triggering of access class barring. For more information, refer to Automatically Triggered Access Class Barring on Cell Level.

2.2.57

FAJ 121 3960: Release with Redirect to LTE Based on Coverage Check The feature Release with Redirect to LTE Based on Coverage Check introduces a check of the LTE coverage before attempting the RWR to LTE, so that the RWR to LTE attempts are avoided when no or insufficient LTE coverage is found. The feature is useful in WCDMA and LTE cell co-sited cases, when LTE is deployed on a higher frequency band than WCDMA, and the LTE cell coverage is lower than for the co-sited WCDMA cell. The coverage check threshold is configurable and is set by the operator to correspond to the coverage of co-sited LTE cells.

46

219/1553-HSD10102 Uen B | 2016-05-20

WCDMA RAN Optional Features

The feature FAJ 121 2174: Release with redirect to LTE is a prerequisite to this feature. For more information, refer to Release with Redirect to LTE Based on Coverage Check.

2.2.58

FAJ 121 3963: LTE Cell Reselection for Advanced LTE Deployments This feature provides the broadcast support of multiple E-UTRA frequency bands to LTE-capable UE units. The LTE-capable UE has therefore more options and opportunities to measure the supported LTE frequency band. High throughput-capable LTE UE can perform the LTE cell reselection to benefit from the LTE network. This feature provides the operator with the flexibility to select the desired measurement bandwidth for the UE to perform the measurements. The LTE frequency bands deployed by the operator can overlap, so the UE must use a larger measurement bandwidth to gather accurate measurement statistics over the whole carrier bandwidth used. By specifying a certain larger bandwidth the UE needs to measure, the measurement can be well-controlled by the operator and be more reliable and accurate. For more information, LTE Cell Reselection for Advanced LTE Deployments.

2.2.59

FAJ 121 4017: Multiple PLMN ID per Core Network Node This feature introduces the additional functionality required to support the One PLMN-ID per Frequency feature for multiple CN operators using the same CN Node.

2.2.60

FAJ 121 4036: Downlink Code Power Based Compressed Mode This feature introduces a new measurement quantity named Downlink Transmitted Code Power to trigger the Compressed Mode (CPM) optimally, avoiding unnecessary CPM for a better performance regarding call drop rate. For more information, refer to Downlink Code Power Based Compressed Mode.

2.2.61

FAJ 121 4125: Radio Dot System in WCDMA The feature Radio Dot System in WCDMA supports the new high capacity indoor small-cell solution Radio Dot System (RDS), as evolution of the main-remote concept optimized for low-power indoor deployments.

219/1553-HSD10102 Uen B | 2016-05-20

47

Optional Features

The feature uses a configuration with new Indoor Radio Units (IRUs) and Radio Dots (RDs) combined with existing DUs. The feature uses a capacity license for each RD. The RDS is easily deployed since Category 7 or 6 (CAT 7/6) cables (new or existing) are used between the IRU and RDs. This reduces the cabling cost to a large extent compared with the Distributed Antenna System (DAS), where coax cables are required. The RD is powered from IRU over CAT cabling. The enhancement with basic O&M support allows operators to manage individual RDs on Cabinet Viewer and Element Manager, such as auto expanding, restarting, locking, unlocking, uninstalling, configuring and locating. The fault localization and report are also improved. Therefore, the enhancement improves the maintainability and manageability of the RDS. The feature is scalable to meet current and future service and device needs. The pooled baseband resource for optimal capacity distribution facilitates adding frequencies, capacity, and technologies, that is, the architecture enables pay-as-you-grow. The indoor solution is fully coordinated with the outdoor network, since the legacy features are supported in the new HW. The feature supports both Single-standard Single Mode (SSSM) and Multistandard Mixed Mode (MSMM) for LTE Frequency Division Duplex (FDD) and WCDMA. RBS 6202 can be equipped with up to 12 IRUs by IRU cascading, and up to 12 sectors are supported. With the distributed IRU configuration introduced, a WCDMA node can be configured as the primary node in a single-standard configuration to control the support system in all cabinets. In RDS, DU or Baseband, and IRUs are placed in the same cabinet. With the enhancement, RBS 6601 with one or two IRUs does not have to be placed together with the main cabinet with DU or Baseband. This feature requires the following features to be active if the RDS feature runs in MSMM mode: •

FAJ 121 4162: Radio Dot System in LTE

•

FAJ 121 1553: Mixed Mode Radio WCDMA

The following features cannot be active together with the RDS feature:

WCDMA RAN Optional Features

•

FAJ 121 3908: Narrowband Interference Rejection

For more information, refer to Radio Dot System.

2.2.62

FAJ 121 4159: Traffic Aware Power Save The feature conserves energy by soft-locking cells during periods with measured low traffic. The locking of resources is done with minimal traffic impact by soft-locking the cells. For more information, refer to Traffic Aware Power Save.

2.2.63

FAJ 121 4160: Multi-Sector per Radio The feature introduces two new Radio Building Blocks (RBBs) and allows one RRUS 32 to be shared between two sectors with 2TX/2RX in each sector. More information about this feature can be found in Multi-Sector per Radio.

2.2.64

FAJ 121 4187: Uplink Coordinated Multi-Point Reception Uplink Coordinated Multi-Point (CoMP) Reception is a function in the WCDMA radio node that enables better reception of uplink signals. It is achieved by expanding the use of softer handover in the radio node. For more information, refer to Uplink Coordinated Multi-Point Reception.

2.2.65

FAJ 121 4244: RACH Overload Protection This feature makes it easier for the UE in different states to share common channels resources to avoid RACH congestion. The feature utilizes Capacity Management functionality to perform admission evaluation, if the UE is upswitching from URA_PCH to CELL_FACH because of the PS data request. For more information, refer to RACH Overload Protection.

2.2.66

FAJ 121 4249: RAN Grand Master With this feature, a radio node can act as Precision Time Protocol (PTP) Grand Master towards other RAN nodes. Global Navigation Satellite System (GNSS) is used as a synchronization source, that is the primary reference clock, for the RAN Grand Master. Radio nodes can provide each other with synchronization and therefore having a GNSS receiver on each site is no longer needed. GNSS can be put on sites providing the best environment for installation of GNSS antennas. For more information, refer to RAN Grand Master.

49

Optional Features

2.2.67

FAJ 121 4250: CS Priority at CS Fallback from LTE When UE has performed Circuit Switched Fallback (CSFB) from LTE to WCDMA or normal CS Radio Access Bearer (RAB) establishment procedure, if a request for PS domain is received first, the RNC sets up the PS signaling connection first accordingly. As a possible result, the CS speech RAB establishment is delayed. Prioritizing of the CS RAB establishment procedure over the PS procedure is introduced during CSFB or the normal CS RAB establishment procedure. For more information, refer to CS Priority at CS Fallback from LTE.

2.2.68

FAJ 121 4365: CS Fallback based on PS Handover This feature enables Mobile Originating and Mobile Terminating speech calls triggered in LTE to be established in WCDMA when no speech service is available in the LTE network. The CSFB based on PS Handover can be initiated in LTE as an alternative solution to CS Voice Fallback from LTE. The feature is based on and extends existing Packet Switched Handover from LTE functionality. First the UE and all its established packet bearers are handed over from LTE to WCDMA using the PS HO procedure. After the HO, Speech RAB is set up in WCDMA using the legacy RAB Establishment procedure. The UE ability to return to LTE can be controlled using legacy RwR triggers. For more information about RwR triggers, refer to Release with Redirect to LTE. For more information about the feature, refer to CS Fallback based on PS Handover.

2.2.69

FAJ 121 4427: Lean DCH Downswitch This feature is introduced to reduce the holding time of Radio Links (RL) during downswitch from CELL_DCH to CELL_FACH. In addition, the feature prioritizes the downswitch over soft handover, HS cell change, and start of CPM. Lean DCH Downswitch introduces the following benefits: •

Increased cell capacity

•

Improved PS and CS accessibility

•

Reduced risk of cell congestion

For more information about this feature, refer to Lean DCH Downswitch.

Therefore, simultaneous DL HS-DSCH transmission from two cells with carriers in different frequency bands is supported by a given UE unit. For a given connection the following are required:

56

•

The two carriers must have the same 64 QAM configuration, that is, if one carrier is configured with 64 QAM and the other carrier cannot be configured without 64 QAM.

FAJ 121 1492: HSDPA Multi-Carrier with MIMO This feature corresponds to DC-HSDPA with MIMO (DC-MIMO) in the 3GPP Rel-9 standard. The feature introduces support for HSDPA Multi-Carrier, with or without 64 QAM, with MIMO using two adjacent carriers. This means that simultaneous DL HS-DSCH transmission using MIMO from two cells, with adjacent carriers, is supported to a given UE unit. For a given connection: •

The two carriers must have the same MIMO (and 64 QAM) configuration, that is if one carrier is configured with MIMO (or 64 QAM), the other carrier cannot be configured without MIMO (or 64 QAM).

•

HSDPA-MC+MIMO is only used with Enhanced L2.

•

HSDPA-MC+MIMO is only used with EUL (2 ms TTI or 10 ms TTI).

2.3.18

FAJ 121 1515: HSDPA RBR QoS Profiling The feature enables the QoS to differentiate between HSDPA users. With the use of the OSS, gold, silver, and bronze HSDPA users are given different relative bit rates, when the Transport Network (TN) limits the HSDPA traffic. The maximum gold or bronze factor is 10. The operator can also configure hsRbrWeight parameter for each SPI separately.

219/1553-HSD10102 Uen B | 2016-05-20

57

Optional Features

This feature requires the following features: •

FAJ 121 1033: HSDPA Introduction Package

•

FAJ 121 1094: Traffic Handling Priority

For more information, refer to HSPA QoS Profiling.

2.3.19

FAJ 121 1537: High Speed Downlink for FACH This feature provides a wider and more dynamic bandwidth for UE in the CELL_FACH state. For UE that supports HS-FACH, the DL FACH transport channel is replaced by the HS-DSCH transport channel. This affects not only the transport of DL user data for UE in the CELL_FACH state, but also signaling on the FACH channel, for example at RRC establishment. No UL HS-DPCCH channel exists, so no HARQ or Channel Quality Indicator (CQI) reporting is sent back to the Node B. The UL is unchanged, that is, the RACH channel is used. The Device Optimized HS-FACH/EUL-FACH improvement allows the operator to configure the network to prevent certain types of UE from entering CELL_FACH and URA_PCH states. It also allows the RNC to multicast the RRC Connection Setup and RRC Connection Reject messages to both R99 FACH and HS-FACH. This mechanism can prevent Key Performance Indicator (KPI) degradation caused by non-3GPP-compliant UE when High-Speed Downlink for FACH is enabled. For more information, refer to High Speed Downlink for FACH.

2.3.20

FAJ 121 1592: Battery Efficiency for High-Speed FACH This feature enables UE units that are in CELL_FACH state to save battery by not decoding the HS-SCCH channel continuously. DRX patterns are introduced that determine when the UE receiver is turned on or off in CELL-FACH state. In 3GPP, this feature is called Enhanced UE DRX. The function is described in the Rel-8 version of the 3GPP specifications. This feature requires the optional RAN feature FAJ 121 1537: High-Speed Downlink for FACH to be activated. For more information, refer to Battery Efficiency for High Speed FACH.

2.3.21

FAJ 121 1673: Channel Element Capacity for HSDPA Smartphones This radio node feature provides a more efficient UL CE ladder for the DCH. The UL CE cost is reduced by a factor of 2 for DCH UL SFs: 4, 8, 16, 32.

2.3.23

FAJ 121 3426: Inter Frequency Load Sharing at Down Switch This feature enables redirecting a UE unit to another frequency or cell, triggered either by inactivity downswitches to FACH or URA states, or by Fast Dormancy. In each cell, the possible configuration can be either to trigger HS IFLS at downswitch, or to configure a specific frequency, to which the UE is redirected at downswitch. If the feature is configured to trigger HS IFLS at downswitch, it depends on the legacy HS IFLS feature (FAJ 121 1467). If the feature aims to configure a specific frequency, it does not depend on any other features. For more information, refer to Load Sharing and Inter Frequency Load Sharing at Downswitch.

2.3.24

FAJ 121 3698: HSDPA Dynamic Power Sharing Feature HSDPA Dynamic Power Sharing provide the possibility to have HS power sharing between cells, sharing radio units (radio building block), for example cells that transmit in the same geographical area (sector).

2.3.27

FAJ 121 3928: Increased Cell Carrier Support for DUW The feature Increased Cell Carrier Support for DUW introduces support for 24 cell-carrier branches (12 cell-carriers with 2RX diversity and 6 cell carriers with 4RX diversity) in DUW 30, DUW 31, and DUW 41. When the feature is activated, the support for the additional cell-carrier branches is achieved by splitting the hardware of the (primary) DU into two separate Baseband Pools (BBPs), with each BBP handling 12 cell-carrier branches. For the (primary) DU hosting two BBP, each of the two BBPs has the same maximum hardware capacity. However, the licensed capacity (for example, for CEs) can be allocated unequally across the BBPs. The total number of CEs allocated to the BBP cannot exceed the maximum hardware capacity associated with the BBP. In the dual DU configurations, the primary DU supports up to 24 cell-carrier branches, and must be a DUW 30, DUW 31, or DUW 41. The secondary DU supports up to 12 cell-carrier branches, and it can be a DUW 10, DUW 11, or DUW 20, as well as DUW 30, DUW 31, or DUW 41. In the dual-DU configuration, the feature enables support for up to 18 cell carriers with 2RX diversity and up to nine cell carriers with 4RX diversity. The feature is not compatible with FAJ 121 2709: HSDPA MC Inter DU Joint Scheduling and FAJ 121 3249: Combined Cell. A precondition for the feature is that the Flexible Carrier Mapping is used for allocating carriers to the BBPs. If the feature is activated, and support for EUL is desired in multiple BBPs, the feature FAJ 121 1518: EUL for Large RBS configurations is required. For more information, refer to Increased Cell Carrier Support for DUW.

2.3.28

FAJ 121 4397: HSDPA Adaptive BLER When determining how much data to be scheduled to a user in a given TTI, the radio node selects the maximum possible Transport Block (TB) size that can be successfully transferred with a given quality target, that is, the Block Error Rate (BLER) target of 10%. This optional feature allows the radio node to transmit a larger TB size by dynamically adjusting the BLER target. The BLER target depends on how quickly the channel varies. The variation is measured for each UE connection. The faster the channel varies, the higher BLER target is used. For more information, refer to HSDPA Adaptive BLER.

64

219/1553-HSD10102 Uen B | 2016-05-20

WCDMA RAN Optional Features

This feature requires the following optional RAN features: •

FAJ 121 1537: High Speed Downlink for FACH

•

FAJ 121 1516: Improved Layer 2

The Device Optimized HS-FACH/EUL-FACH allows the operator to configure the network to prevent certain types of UE from entering CELL_FACH and URA_PCH states. It also allows the RNC to multicast the RRC Connection Setup and RRC Connection Reject messages to both R99 FACH and HS-FACH. This mechanism can prevent KPI degradation caused by non-3GPP-compliant UE when Enhanced Uplink for FACH is enabled. The feature introduces the support for the Extended Acquisition Indicator (E-AI). With the E-AI, up to 32 common E-DCH resources can be configured in a cell. A radio node can allocate any of these resources to the UE, irrespective of the preamble signature selected by the UE. The number of EUL-FACH preamble signatures and associated common E-DCH resources are no longer related. Therefore, with the E-AI introduced, the accessibility for EUL-FACH-capable UE is improved. For more information, refer to Enhanced Uplink for FACH.

2.4.12

This feature increases the throughput for high data rate users in a multi-path or multi-user radio environment, or both. It preserves coverage for low data rate users in cases where both high and low data rate users exist. For more information, refer to Interference Suppression for all Bearers.

2.4.15

FAJ 121 2444: Uplink Fast Congestion Control The Uplink Fast Congestion Control feature controls the RoT towards its target, which determines the operator-desired coverage. The RoT values above the maximum RoT are reduced. With more stable RoT, the need for margins is reduced and a higher EUL throughput can be achieved during maintained coverage. For more information, refer to Uplink Fast Congestion Control.

2.4.16

FAJ 121 2598: CE Extension for EUL The CE Extension for EUL feature extends the radio node licensed CE by 50% and increases the EUL traffic.

2.4.18

FAJ 121 3214: Channel Element Efficiency for EUL This feature reduces the static UL CE cost for EUL 2 ms TTI users from two CEs to one CE. The CE resources made available by the reduced cost increase the headroom for all UL services such as AMR, EUL 2ms TTI, EUL 10ms TTI users, or EUL dynamic bit rate. With the feature activated, the static UL CE cost is the same for both EUL 2ms and 10ms TTI users. This feature requires the optional RAN feature, FAJ 121 1883: Channel Element Capacity for EUL Smartphones. For more information, refer to EUL Migration and Activation and Capacity Management.

FAJ 121 3293: Overhead Reduction for Non-CPC Smartphones The Overhead Reduction for non-CPC Smartphones feature enables the SRNC to reset the SIR target to a predefined SIR value when an EUL/HS connection is established and no UL data packet transmission is performed for a certain time. As a result, the UL interference is reduced. Reduced interference improves UL capacity since the amount of UL interference depends on the UL DPCCH SIR target. This is the case when no UL data transmission takes place, for example, when the UE waits to be downswitched. For more information, refer to Overhead Reduction for non-CPC smartphones.

2.4.20

FAJ 121 3941: EUL Low Latency Prescheduling The EUL Low Latency Prescheduling feature introduces more advanced EUL Scheduler and Uu Load Estimation handling that improves the average end-user performance by decreasing the uplink transmission latency. To be active, this feature requires the optional RAN feature FAJ 121 2444: Uplink Fast Congestion Control. For more information, refer to EUL Low Latency Prescheduling.

2.5

Transport Functionality This section describes Transport Functionality Optional Features.

2.5.1

FAJ 121 1101: Iub Transport Split for Best Effort Data This feature allows using medium- to-low-cost public IP transport services. These services are typically based in the xDSL (meaning all types of Digital Subscriber Line), for the WCDMA RAN Best Effort data traffic. Parallel TDM and Ethernet Iub transport links with different QoS characteristics to the same WCDMA radio node allow these services to be medium-to-low cost. The preferred way of creating an Iub transport split for best effort data is to use FAJ 121 1311: ATM and IP dual stack in RBS. For more information, refer to Transport Network Functionality.

2.5.2

FAJ 121 1340: Soft Congestion Based on Iub The Soft Congestion based on Iub provides the possibility to perform soft-congestion on Guaranteed Bit Rate (GBR) connections. When the Iub congestion occurs, this feature can prevent a low priority connection to make resources available for high priority RABs.

67

Optional Features

This feature requires the optional RAN feature FAJ 121 1327: Unified ATM/IP Admission Control for Iub. To allow setting of allocation or retention priority attributes, the feature FAJ 121 1093: Flexible QoS and Allocation/Retention Handling must be installed and activated. For more information, refer to Transport Network Configuration, Transport Network Functionality, Capacity Management, and Transport Network Performance Monitoring.

2.5.3

FAJ 121 1395: Ethernet Link Aggregation The Ethernet Link Aggregation is used to reach higher aggregated bit rate on the Iu, Iur, and Iub interfaces and to offer link redundancy. This feature enables using several Ethernet links in Link Aggregation Groups (LAGs) to reach higher aggregated bit rates. This is as a function supported in all Ericsson Connectivity Packet Platform (CPP)-based nodes that are equipped with ET-MFX or Common Main Switching Board (CMXB) boards. For more information, refer to Transport Network Functionality and IP Transport Network Configuration.

2.5.4

FAJ 121 1401: Soft Congestion of 2ms EUL Users This feature allows 2ms TTI EUL users, not originating over Iur, to switch to 10 ms TTI in the event of an UL RN soft congestion situation on the radio node UL HW resources. This lowers the cost in terms of CEs for each subscriber for EUL users. This feature requires the optional RAN feature, FAJ 121 1317: Enhanced uplink 2ms TTI. For more information, refer to Capacity Management and Channel Switching.

2.5.5

FAJ 121 1466: Layer 2 Gateway Port This feature provides a way of inter-connecting the RNC to an external network over multiple links from multiple CMXBs, RNC 3820, without running the Rapid Spanning Tree Protocol (RSTP) toward external switches. As a result, redundancy between ports or LAGs on different CMXBs can be achieved without using RSTP toward the network connected to the RNC. For more information, refer to Transport Network Functionality and IP Transport Network Configuration.

WCDMA RAN Optional Features

2.5.6

FAJ 121 1478: Iub over Satellite This feature enables using satellite links for the Iub connectivity between the RNC and the radio node. Iub over satellite is supported by a dedicated RNC with specific parameter settings for extended delay and delay variation tolerance. The base stations that communicate over satellite can be geographically spread out. However, since they are connected to the same RNC, the satellite links can be used as a common resource, thus enabling reduced total satellite bandwidth. The Improved Robustness for Iub over Satellite enhancement, introduced in W16.0, enables tuning thresholds for detection of abnormal conditions. The frequency of disturbances detected by the Node Synchronization and Frame Synchronization functions is minimized and false detection of Transport Network problems is eliminated. The system is thus prevented from recognizing high delay variation as abnormal Transport Network condition and is resistant to delayed communication between RNC and radio node. The improved Frame Synchronization timing adjustment algorithm recognizes and ignores redundant Timing Adjustment frames, which prevents unnecessary timing offset changes, synchronization over-adjustments, and oscillations. Once the feature enhancement is enabled, all Iub links on a given RNC are affected. The following features are recommended in conjunction to using Iub over satellite:

2.5.7

•

FAJ 121 440: System Integrated GPS Network Synchronization (for network synchronization)

•

FAJ 121 1327: Unified ATM/IP Admission Control (to limit the GBR traffic to a level that can be supported by the satellite connection)

FAJ 121 1553: Mixed Mode Radio WCDMA This feature allows two radio standards, WCDMA and GSM, to share physical radio unit or remote radio unit, and antenna system resources. The Mixed Mode license has to be enabled if any sectors are configured with RBBs dedicated for Mixed Mode (for example RBB 12_2a or RBB 22_4b). This means that the license is needed even if the radio unit or remote radio unit is not shared. The feature is supported for DU Radio Node (RBS 6000 family) using MSMM-capable radio units or remote radio units. MSMM synchronization based in the Common Public Radio Interface (CPRI) enables use of CPRI interfaces for handling MSMM synchronization between nodes. It is supported in configurations with single DU for each RAN radio node and multi-DU for each RAN radio node. This feature requires the basic RAN feature FAJ 121 1554: Absolute Time Synch.

219/1553-HSD10102 Uen B | 2016-05-20

69

Optional Features

From W12.1 this feature is enhanced with support for Mixed Mode between WCDMA and LTE. Before the feature FAJ 121 1553: Mixed Mode Radio WCDMA can be used, fulfill the following conditions : •

The feature FAJ 121 1554: Absolute Time Synch is activated.

•

All sectors planned to run in Mixed Mode need to be equipped with a Multi Standard Mixed Mode radio unit or remote radio units.

The feature FAJ 121 1553: Mixed Mode Radio WCDMA is activated by setting the parameter featureStateMixedMode to ACTIVATED. The feature is deactivated by setting the parameter featureStateMixedMode to DEACTIVATED. For more information, refer to Network Upgrade Guide, Software Management, and Fault Management.

2.5.8

FAJ 121 1557: QoS for RAN Sharing This feature introduces support for individual Radio Network Level (RNL) QoS Profiles for each CN operator in a shared RAN environment. The individual QoS settings, received from the CN, can then be remapped in the shared RAN to have their own settings for the services used by different operators. The RNL QoS Profile is used for determining the Scheduling Priority Indicator (SPI) mapping based on Iu attributes. The derived SPI values are then used in the EUL and HS schedulers, to activate flow control and to determine Iub transport settings for HSPA RABs. This feature is an improvement when combined with the following existing Shared Network features: •

FAJ 121 974: Shared RAN (MOCN)

•

FAJ 121 1301: One PLMN-id per frequency

This feature requires the basic RAN feature FAJ 121 1093: Flexible QoS and Allocation/Retention handling. The following features are recommended in conjunction to using QoS for RAN Sharing, to get the full effect of the new feature: •

FAJ 121 1093: Flexible QoS and Allocation/Retention Handling

•

FAJ 121 1094: Traffic Handling Priority

•

FAJ 121 1382: HSPA QoS Scheduling Priority based on ARP

For more information, refer to QoS Handling, QoS Configuration, and Shared Network.

WCDMA RAN Optional Features

2.5.9

FAJ 121 1664: AQM Based Congestion Control for HSDPA This feature introduces TN congestion control based in Active Queue Management (AQM) that is the next generation of HSDPA congestion control for PS Interactive and PS Background user data traffic in an HSDPA serving cell. AQM based Congestion Control for HSDPA is an alternative to the existing HSDPA Flow Control algorithm on the IP-based TNs. The benefit of the AQM based Congestion Control for HSDPA is the improved performance for short transfers at high rates such as the web page download to the Smart Phone. The AQM Based Congestion Control for HSDPA feature introduces the same congestion behavior in RAN as in the Internet. This enables LTE and WCDMA to co-exist on the same TN link and queue. This feature can be used in parallel with HSDPA Flow control in the RNC, however, not within a radio node or radio nodes that share a TN queue over an Iub or Iur link. This feature requires the optional RAN feature FAJ 121 1033: HSDPA Introduction Package. For more information, refer to AQM Based Congestion Control for HSDPA, HSDPA Flow Control, and HSPA QoS Profiling.

2.5.10

FAJ 121 1670: Dynamic Iu and Iur Signaling The feature allows the configuration of a Horizontally Distributed (HD) Signaling System No. 7 (SS7) signaling stack. The feature increases RANAP, RNSAP, and Position Control Application Part (PCAP) signaling capacity with distribution of functionality to MPs. This results in a small increase in load on each mMP but reduce load on central processors. This feature can only be used when SS7 uses IP transport (ATM is not supported). For more information, refer to Dynamic Iu and Iur Signaling Migration and Activation.

2.5.11

FAJ 121 2095: Two-Way Active Measurement Protocol Responder This feature enables support for Two-Way Active Measurement Protocol Responder on the DU in WCDMA. The Two-Way Active Measurement Protocol (TWAMP) specified in IETF RFC 5357 is a protocol that enables performance measurements of packet delay, packet delay variation, packet loss, packet duplicates, packet reordering, connectivity, and so on, for each Differentiated Services Code Point (DSCP) between two reference points in an IP network. For more information on TWAMP, refer to Two-Way Active Measurement Protocol Responder.

219/1553-HSD10102 Uen B | 2016-05-20

71

Optional Features

2.5.12

FAJ 121 2117: Egress IP Traffic Shaping This feature enables support for Egress IP Traffic Shaping for DU Radio Node, that can be used to improve the characteristics of the TN for DU Radio Nodes. If the TN does not provide QoS handling but has a known and constant bandwidth, egress shaping is a way to avoid IP packets to be lost higher up in the network. For more information, refer to IP Transport Network Configurationand Transport Network Functionality.

2.5.13

FAJ 121 2561: 1588v2 Frequency Synchronization The feature supports for the synchronization of an ordinary clock slave (in the radio node) and allows the operator that has a 1588 network, to select Precision Time Protocol (PTP) as synchronization source for sync over IP for the radio node. The feature supports frequency synchronization for the DU Radio Node. For more information, refer to 1588v2 Frequency Synchronization.

2.5.14

FAJ 121 2602: Iub Supporting Internet-Grade Transport This feature enables service continuity and full capacity gain in the network when introducing Metro Cells into a macro network. The Internet-grade transport that is used usually of Metro Cell deployment has a delay of up to 100 ms and a delay variation of up to 30 ms. The last mile bandwidth can range from a few to more than 50 Mbps. The transport links can be a shared resource with no QoS mechanisms implemented, which can generate both delay and packet drop at congestion. Note:

To use Iub Supporting Internet-Grade Transport, activate the Dynamic RLC and MAC configurations feature. The feature is basic and allows setting RLC timers based on calculated RLC RTT estimate, based on node sync parameter maxEpsilon. The main feature benefit is that it supports systems with long Iub or Iur delays.

For more information, refer to Iub Supporting Internet-Grade Transport.

2.5.15

FAJ 121 3272: Synchronous Ethernet The Synchronous Ethernet feature enables the DU Radio Node to use Ethernet signals on SFP-optical or SFP-DAC (Small Form-Factor Pluggable-Direct Attached Cable) ports (DUW 10, DUW 20, and DUW 30, as well as DUW 11, DUW 31, and DUW 41) and electrical ports (DUW 11, DUW 31, and DUW 41) as frequency synchronization references. At the Ethernet ingress port, the frequency is extracted from the bit rate and connected to the Timing Device integrated in the DU. Ethernet Synchronization Message Channel (ESMC) is introduced on DU to add quality signaling in the Synchronization Status

WCDMA RAN Optional Features

Message (SSM), used by the radio node to ensure that the synchronization reference quality meets the 3GPP radio requirement. For more information, refer to Synchronous Ethernet.

2.5.16

FAJ 121 3429: Two-Way Active Measurement Protocol Responder for RNC This optional feature adds TWAMP Light Responder support in the Evo Controller. The TWAMP Light Responder is, as part of the design base, supported not only on the DU for RBS 6000, but now also on the Evo Processor Board (EPB), for the Evo Controller. The same capacity characteristics that exist for the TWAMP Responder on the DU are also valid for the EPB. With an integrated TWAMP Responder in the Evo Controller, performing active measurements over IuPS, IuCS, and Iur is possible. The TWAMP Responder reflects received test packets back to the sender, enabling calculation of two-way IP performance metrics. This feature inherits all benefits that come with the TWAMP Responder feature in RBS 6000, but adds the ability to perform active IP performance measurements over IuPS, IuCS, and Iur if the RNC is an Evo Controller. For more information, refer to Two-Way Active Measurement Protocol Responder for RNC.

2.5.17

FAJ 121 3586: IPsec The IP Security (IPsec) feature provides an encrypted and integrity-protected transport solution for Iub and Mub interfaces between the DU Radio Nodes and the standard Security Gateway (SEG) nodes. The IPsec function enables secure communication between network nodes through IPsec tunnels over untrusted transport networks. In addition, IPsec supports the following functions: •

Network Address Translator Traversal (NAT-T), which enables IPsec Encapsulating Security Payload (ESP) to pass through a NAT device.

•

Fully Qualified Domain Name (FQDN) for SEGs, which enables SEGs to be addressed with FQDNs during IPsec tunnel setup.

With these functions, IPsec greatly increases network flexibility and reduces the cost for radio node deployment. For more information, refer to IPsec.

2.5.18

FAJ 121 4183: IP Flow Monitoring This feature allows the monitoring of the traffic flow between the radio node and any configured remote IP address, providing a series of values recorded at preconfigured sampling intervals.

For more information, including activation and deactivation, refer to Ethernet OAM Service.

2.5.20

FAJ 121 4557: TWAMP Initiator This feature enables monitoring of characteristics of TN links and recording statistics in the baseband radio node in regular statistical ROP files. TWAMP initiator links toward responder functionality in the RNC or to another TWAMP Light responder. TWAMP Initiator in Baseband enables controller functionality, and makes it possible to actively measure the characteristics in the RAN back-haul. For more information, refer to TWAMP Initiator.

2.6

RAN Management This section describes RAN Management Optional Features.

2.6.1

FAJ 121 1352: Find Faulty Antenna Data This feature allows performance measurement of the antenna system at every cell or sector. The data is collected from the antenna receive branches in RBS, and is processed in the OSS-RC. The system can identify poorly performing antenna installations and provide an indication of the fault type. This feature needs the OSS-RC feature FAJ 121 1285: Find Faulty Antenna Expert for WCDMA.

WCDMA RAN Optional Features

2.6.2

FAJ 121 1444: Real-Time Traffic Flow Indicator The feature provides the possibility to observe in real time the number of calls or users and user data flow handled by an RNC. The RNC Element Manager (EM) is used to retrieve the information on the demand basis. This real-time indication is complementary to the existing Statistical Observability and GPEH features that also provide observability of the traffic situation, but only on a Result Output Period (ROP) period basis. With this feature, the operator can immediately observe whether the traffic flow in an RNC is affected by a fault or operator initiated action like reconfiguration, hardware exchange or software upgrade. The Operator retrieves the information by reading the following attributes in the RNC MO RncRealtimeIndicators :

2.6.3

•

Attribute fachDchHsUsers which is the current number of UEs in state FACH/DCH and HS in the RNC. The document Connection Handling contains more information about the UE state handling.

•

Attribute iuThroughputPs which is the Iu PS throughput in RNC in Mbit/s.

•

Attribute iuThroughputCs which is the Iu CS throughput in RNC in Mbit/s.

FAJ 121 1675: GPEH Capacity Increase - Reduced ROP Periodicity This feature introduces a higher time resolution of the performance monitoring. It reduces GPEH recording periodicity, from a 15 min ROP period to a 1 min ROP period and increases GPEH event capacity. This feature requires the following two features: •

FAJ 121 1001: Recording Observability for GPEH (WRAN)

•

FAJ 121 173: General Performance Event Handling (OSS-RC)

For more information, refer to Performance Management in WCDMA, Performance Recording Characteristics, and General Performance Event Handling.

2.6.4

2.6.5

FAJ 121 2527: UE Real-Time Trace The UE Real-time Trace feature introduces the possibility to schedule and set up streaming of a UE Traffic Recording (UETR) event from RNC nodes to a user-defined system, including OSS-RC, or any other external server. The UE Real-time Trace supports UETR streamed data initiation. When UE Real-time Trace data streaming to the OSS-RC server is enabled, the data can be streamed to a common file or viewed in real time, or both. These events can be viewed, for example, in the Ericsson Network IQ (ENIQ) events. For more information, refer to UE Real-time Trace.

2.6.6

FAJ 121 3930: UE Quality Measurement Event 5A The UE Quality Measurement Event 5A feature provides the support to set up or schedule a new UE quality measurement ‘‘event 5A’’ using an OSS-RC Measurement Result Recording in WCDMA (MRR-W) application. It introduces a GPEH Profile setup/schedule in the MRR-W (for that particular measurement only) for the measurement activation and capturing. For more information, refer to UE Quality Measurement Event 5A.

2.6.7

FAJ 121 4163: Real Time Security Event Logging The feature Real Time Security Event Logging introduces logging of security-related events in real time. As a result, the operator can react to potential security breaches faster. Detection and reporting of the events is done in real time and the events are transported to the external server. A subset of security-related log events in the node is sent to an external Syslog server, using either User Datagram Protocol (UDP) or secure Transport Layer Security (TLS) over TCP. The feature is license-controlled on the RNC and the radio node level. For more information, refer to Security Management.

2.7

Licensing Principles This section describes Licensing Principles Optional Features.
