2 Radio resource management features 2.1 RAN3228: CS Call Re-establishment over Iur Benefits, functionality, system impact, reference data of the feature.
DRAFT VERSION
The RAN3228: CS Call Re-establishment over Iur feature enables a re-establishment of a lost AMR call over Iur in anchoring, or with serving radio network subsystem (SRNS) relocation.
2.1.1 RAN3228 benefits The RAN3228: CS Call Re-establishment over Iur feature: • • •
improves call drops performance over Iurs. enables operators to select a CS call re-establishment over Iur either with SRNS relocation or for anchoring. works in multi-vendor environment.
2.1.2 RAN3228 functional description When a UE loses radio connection during CS voice call, it starts to search for a suitable cell to camp. If the UE regains the radio connection within a pre-defined time, it sends the RRC:CELL UPDATE to RNC, which in this case is the drifting RNC (DRNC). DRNC forwards the Cell Update to the serving RNC (SRNC). If possible, the SRNC starts to allocate the radio resources of the CS voice call over the Iur in DRNC, and reestablishes the CS voice call to the UE. CS Call Re-establishment for Anchoring The circuit-switched call (CS call) re-establishment over Iur for anchoring is suitable for the Iur interface between Nokia SRNC and other Vendor's DRNC. It can also be activated in the Nokia RNC - Nokia RNC Iur interface. In anchoring the SRNC controls the call re-establishment, and remains in control of the call after re-establishment. The SRNC allocates the radio resources over Iur in the DRNC and re-establishes the call to the UE. When the UE with a CS voice call loses radio connection, RNC receives the radio link (RL) Failure message from all the BTSs to which UE has a radio link. Upon receiving RL Failure, the SRNC starts the RRC_ConnRe-estab_T314 timer. If the UE provides Cell Update message before RRC_ConnRe-estab_T314 and UE timer T314/T315 have expired, RNC starts the RRC connection re-establishment. During the RRC connection re-establishment procedure the CS voice call connection moves back to the Cell_DCH state with a Cell Update Confirm message. The interrupted service continues when the radio link synchronization is restored. Figure 1

CS Call Re-establishment with SRNS Relocation The CS Call re-establishment over Iur with SRNS relocation works only for the NokiaNokia Iur interface and it is UE sensitive.
g
Note: The CS Call Re-establishment with SRNS Relocation is used by default only with Rel-9 and newer UEs. For Rel-8 and older UEs the CS call re-establishment over Iur is done in anchoring. SRNC initiates SRNS relocation procedure and Target RNC sends Cell Update Confirm including the new U-RNTI and parameters for call re-establishment. When SRNC receives the cell update from target RNC, it checks whether the following requirements are met: • • • •

WCDMA 17 Feature Descriptions and Instructions
If all of the above requirements are met, SRNC initiates SRNS relocation procedure by sending Relocation Required to the involved CN nodes.
DRAFT VERSION
When the Target RNC receives a Relocation Request from CS CN, it checks if the RAN3228: CS Call Re-establishment over Iur feature is enabled with the CS Call reestablishment over Iur with SRNS relocation. If the functionality is enabled, the target RNC accepts the relocation and continues with resource allocation procedure and initiates Radio Link Setup towards BTS. The Target RNC sends Cell Update Confirm to the UE with new U-RNTI and parameters for call re-establishment. When the UE sends a successful response for the Cell Update Confirm message, SRNS relocation is completed and Target RNC becomes a new SRNC. At this point it sends Relocation Complete to CN. The resources in the old SRNC are released, and the CS call continues. Figure 2

2.2 RAN3079: Dedicated Priorities Benefits, functionality, system impact, reference data of the feature. The RAN3079: Dedicated Priorities feature enables a flexible use of the dedicated (subscriber-specific) priorities in the absolute priority-based criteria for inter-frequency and inter-RAT (GSM and LTE) cell reselection. With the dedicated priorities the operator is able to define subscriber group-specific camping strategies and can prevent the movement to LTE for those subscribers who do not have LTE subscription.
2.2.1 RAN3079 benefits The RAN3079: Dedicated Priorities feature provides the following benefits: • • •
18
Allowing defining subscriber group-specific camping strategies. Enabling giving priorities to a UE for selecting Radio Access Technology (RAT): LTE, WCDMA or GSM, and the frequency within each RAT. Enabling a different handling of different roaming user groups.

Preventing a UE from camping to LTE for LTE devices without LTE subscription. Allowing network-sharing operators to use individual priority tables.
2.2.2 RAN3079 functional description
DRAFT VERSION
The RAN3079: Dedicated Priorities feature enables inter-frequency and inter-RAT (GSM, LTE) cell reselection based on the dedicated (subscriber-specific) WCDMA/LTE/GSM frequency priorities. When the RAN3079 feature is activated, the RNC sends the dedicated WCDMA/LTE/GSM frequency priorities to the specified Rel-8 or newer UEs in the RRC: UTRAN MOBILITY INFORMATION message after RAB setup and during the SRNC relocation procedure. The UEs in question use the dedicated priorities for cell reselection in the states: Idle, Cell_PCH, and URA_PCH instead of the absolute priorities broadcasted in the System Information Block type 19 (SIB19) message. The dedicated priorities are valid until the UE leaves the radio network or the dedicated priorities are resent. The cell reselection strategy (subscriber-specific, or user groupspecific) is controlled by the PLMN ID of the subscriber and/or the Subscriber Profile ID (SPID) for RAT/Frequency priority IE sent from the CN to the RNC in the RANAP: COMMON ID, DIRECT TRANSFER or the RELOCATION REQUEST message. The operator is able to define the WCDMA/LTE/GSM frequency priorities dedicated to a certain subscriber's PLMN ID, to a certain SPID value or to a certain PLMN ID and SPID combination. It is also possible to define the WCDMA/LTE/GSM frequency priorities that are dedicated to all roaming subscribers. In case of RAN sharing, each operator can define the dedicated priorities independently. In the Cell_DCH state, the RNC does not hand over or redirect a UE to the LTE carrier frequency that is not included in the dedicated priority information sent to the UE. The dedicated priority information does not affect inter-frequency and GSM handover control in the Cell_DCH state. The RAN3079 feature introduces the following managed objects: •
•
WSP (WCDMA Subscriber Profile): It contains the attributes which are used to generate the Subscriber Profile ID (SPID) mapping table in the RNC. WDP (WCDMA Dedicated Priority): It contains the priority and frequency information of the different radio access technologies for a specified SPID.

2.2.3 RAN3079 system impact RAN3079: Dedicated Priorities impact on features, interfaces, network management tools, and system performance and capacity. Interdependencies between features The RAN3079: Dedicated Priorities feature is impacted by the following features: • • • • • •
RAN2067: LTE Interworking RAN2881: WCDMA and GSM layer priorities RAN3069: RSRQ-based LTE Reselection RAN2717: Smart LTE layering RAN2264: Smart LTE handover RAN2980: Measured based LTE layering
With the RAN2067 and the RAN3069 features, the absolute priority-based criteria is enabled for inter-RAT cell reselection to LTE. With the RAN2881 feature, the absolute priority-based criteria are enabled for interfrequency cell reselection and for inter-RAT cell reselection to GSM. The RNC broadcasts the absolute camping priorities to all UEs via system information (SIB19). If the dedicated priorities are sent to a UE, the dedicated priorities overwrite the broadcasted priorities.
g
Note: Even if the absolute priorities are not used in the RNC/Cell, the RNC sends dedicated priorities for a UE in Cell_DCH or Cell_FACH state as the RNC does not detect what kind of services the RNC/Cell offers when the UE needs the dedicated priorities in IDLE, Cell_PCH, and Cell_FACH states. If such dedicated priorities which do not include some LTE frequencies are sent to a UE, then handovers or re-directions to LTE are not done for this UE to those frequencies by the RAN2717: Smart LTE Layering, the RAN2264: Smart LTE Handover, and the RAN2980: Measurement Based LTE Layering feature.

The RAN3266: Enhanced Mass Event Handler feature enhances the RAN2879: Mass Event Handler feature.
2.4.1 RAN3266 benefits The RAN3266: Enhanced Mass Event Handler feature provides the following benefits: • •
DRAFT VERSION
•
Improved cell capacity and user throughput Improved call success rate Efficient HSPA/HSDPA resource rotation upon high load conditions
2.4.2 RAN3266 functional description The RAN3266: Enhanced Mass Event Handler feature contains the following subfeatures: •
•
•
Issue: 01A DRAFT
Additional received total wideband power (RTWP) and HSUPA throughput inputs to trigger mass event handler (MEH) functions The RAN2879: Mass Event Handler feature detects the MEH load state of the cell from the number of the cell packet-switched (PS) queue items for non-real time dedicated traffic channel (NRT DCH/DCH) or high speed packet access (HSDPA/UL DCH) allocations. The RAN3266 feature introduces the cell RTWP and cell HSUPA throughput as new triggers for MEH with additional preventive and reactive load state handling. Preventive actions, including: dynamic or automatic adjustment of the HSUPA power offsets, initial signal-to-interference ratio (SIR) target configuration, high HSUPA block error ratio (BLER) target configuration, and HSUPA 2ms Transmission Time Interval (TTI) restriction, are automatically activated based on the RTWP input. This functionality optimizes the RTWP level and the upink (UL) performance of the cell. Reactive actions include the dynamic temporary maximum number of HSUPA users (EMEH DMHU) adjustment, which dynamically triggers the HSUPA limitation in the cell if the RTWP level increases too much or HSUPA user throughput decreases too low. HSUPA user limitation is then automatically tuned to a level which provides the optimum RTWP and HSUPA throughput during the high load conditions. Preventive actions are used in parallel with reactive actions. Load state triggers, apart from the fixed temporary maximum number of HSUPA users (MEH TMHU) introduced by the RAN2879: Mass Event Handler feature, are still available with the RAN3266 feature. The operator can configure the used EMEH states (preventive, reactive, and load) on cell basis. Limitation of UL NRT DCH bitrates A temporary uplink non-real time dedicated traffic channel (UL NRT DCH) maximum bit rate is determined based on the cell state. The temporary maximum bit rate is used during initial allocation and upgrade of the UL NRT DCH. This prevents further increase of UL noise in an already loaded cell. In case of diversity handover from an unloaded cell to the loaded cell during active state, the high UL NRT DCH bit rates are downgraded. Soft handover (SHO) prioritization over the HSUPA TTI reconfiguration If EMEH prohibits the HSUPA 2 ms TTI allocation in case of SHO branch setup or addition, the SHO branch setup or addition (active set update) is done first with the existing HSUPA 2 ms TTI allocation. HSUPA TTI reconfiguration from 2 ms to 10 ms

is started after active set update is completed. The same change is implemented generically to the HSUPA 2 ms TTI prevention function of the RAN2879: Mass Event Handler feature. Increased UE periodic measurement reporting interval UE periodic reporting of the common pilot channel (CPICH) Ec/N0 and CPICH received signal code power (RSCP) measurement increases the UL interference even if the UL data transfer is low or zero. This sub-feature increases the reporting interval of the UE periodic measurement from default 500 ms to 2 s when any cell of the active set is in EMEH state.

2.4.3 RAN3266 system impact RAN3266: Enhanced Mass Event Handler impact on features, interfaces, network management tools, and system performance and capacity. Interdependencies between features The RAN3266: Enhanced Mass Event Handler (EMEH) feature impacts the following feature: •
RAN2879: Mass Event Handler (MEH) RAN2879: Mass Event Handler feature is a pre-requisite for the RAN3266 Enhanced Mass Event Handler feature. However, the RAN3266 feature can be used in the cell also if any or every sub-feature of the RAN2879 feature is disabled. When both of the features are enabled in the same time, the sub-features of the RAN2879 feature have the following inter-operability with the RAN3266 feature: –

Increased traffic volume measurement (TVM) pending time Usage of the increased TVM pending time is triggered by the MEH load state because of the RAN2879 functionality. The RAN3266 feature introduces new triggers for the increased TVM pending time. The RAN3266 feature makes it possible to configure the EMEH cell states (EMEH preventive state, EMEH reactive state, and EMEH load state) where the increased TVM pending time function is used. Temporary maximum bit rate for UL DCH: Usage of the temporary maximum bit rate for UL DCH is triggered by the MEH load state because of the RAN2879 functionality. The RAN3266 feature introduces new triggers for the temporary maximum bit rate for UL DCH. The RAN3266 feature makes it possible to configure the EMEH cell states (EMEH preventive state, EMEH reactive state, and EMEH load state) where the temporary maximum bit rate for UL DCH function is used. Temporary maximum number of HSUPA users: Usage of the RAN2879 fixed temporary maximum number of HSUPA users (MEH TMHU) is disabled in the cell by the system (control plane) if usage of the RAN3266 dynamic HSUPA user limitation (EMEH DMHU) is enabled in the cell. Dynamic temporary maximum number of HSUPA users (EMEH DMHU) replaces the usage of the fixed MEH TMHU. If EMEH DMHU is not enabled in the cell, the RAN2879 fixed MEH TMHU is used in a regular way. Increased channel quality indicator (CQI) feedback cycle: Usage of the increased CQI feedback cycle is triggered if the number of HSDPA users in the cell exceeds a pre-defined threshold. This function works in a regular way irrespective of the RAN3266 feature.

2.5 RAN3263: Enhanced Power Control Benefits, functionality, system impact, reference data of the feature.
DRAFT VERSION
The RAN3263: Enhanced Power Control feature introduces power control enhancements in both RNC and BTS to ensure a better and faster reaction to the changing cell load and UE radio conditions. Power control enhancements are achieved by introducing a set of improvements in the outer loop power control (OLPC) algorithm.
2.5.1 RAN3263 benefits The RAN3263: Enhanced Power Control feature provides the following benefits: • • • • •
More efficient power control provides bigger capacity and better service quality. Better and faster power control that results in less cell overload and smoother recovery from cell overload conditions. Reduced intra-cell and inter-cell interference. Better performance at the cell edge. Increased cell capacity, especially during mass events.
2.5.2 RAN3263 functional description The RAN3263: Enhanced Power Control feature introduces the following enhancements: Subfeature 1: Enhanced Received Total Wideband Power (RTWP) overload handling BTS indicates cell’s Received Total Wideband Power (RTWP) load level to RNC using spare fields in the DCH/E-DCH Frame Protocol. Outer loop power control (OLPC) at RNC adjusts the signal-to-interference ratio (SIR) target based on the load conditions. RTWP Normal
No OLPC behavior changes in RNC.
RTWP Overload
OLPC operation is modified in RNC so that the SIR target is not increased to avoid further worsening of the RTWP load in the cell.
RTWP High Overload
OLPC in RNC lowers SIR targets for all UEs in the cell. In this case the cell is already in a pole capacity and SIR target decrease is needed to save connections.
With this functionality OLPC is more sensitive to the cell RTWP what results in faster corrective actions in case of the RTWP overload.

OLPC RNC Subfeature 2: Enhanced Outer Loop Power Control This subfeature contains the following enhancements: • •
HSUPA minimum SIR target change SIR target setting optimization: – – – – –
•
Valid for both DCH and HSUPA cases. The SIR target of the first radio link (RL) of the user decreases as long as the first block error is received or until the legacy minimum SIR target value is achieved. The SIR target changes are faster if SIR target is not in converged area. The SIR target decreases for silent PS service users. Cancellation of the SIR target change according to block error ratio (BLER) state change.
Faster OLPC for DCH: –
discontinuous transmission (DTX) period, minimum step size for SIR target modification, and SIR target modification interval set in the same way as for HSUPA cases.
Subfeature 3: Power control enhancements in BTS This subfeature introduces power control enhancements in BTS and SIR target decrease for specific UEs based on RTWP. The threshold of an RTWP limitation for 2 ms HSUPA users in the BTS is increased to ensure that the overload is detected before the BTS component. Cell overload is handled in case RTWP is higher than target + 6 dB irrespective of the transport protocol (TP) domain overload state. In addition, SIR adaptation based on transport format combination indicator (E-TFCI) is introduced at BTS level. As OLPC is not always able to follow the transport block (TB) size changes fast enough, a certain TB size-specific correction factor is introduced in BTS on top of the SIR target given by RNC. With this subfeature, the SIR target is better aligned with the changing TB sizes. In addition BTS user part (UP) is made more sensitive to RTWP. RAN3263 general information RAN3263 is controlled by an RNC level license with an activation parameter in RNC for subfeature 1 and 2 and activation parameter in BTS for subfeature 3. The RNC sends license and subfeature 1 activation information to the BTS using NBAP: PRIVATE MESSAGES (Configuration Data). In the RNC the feature is used based on the license

and the activation parameter. In the BTS subfeature 1 is used based on the activation information received from the RNC and subfeature 3 is used based on the license information received from the RNC and feature activation parameter in the BTS.
2.5.3 RAN3263 system impact RAN3263: Enhanced Power Control impact on features, interfaces, network management tools, and system performance and capacity. Interdependencies between features
DRAFT VERSION
The following features complement the RAN3263: Enhanced Power Control feature: • • •
RAN2302: Dynamic HSUPA BLER RAN2886: Faster OLPC RAN3266: Enhanced Mass Event Handler feature is recommended to be used with RAN3263 feature for better uplink interference management.
Impact on interfaces The RAN3263: Enhanced Power Control feature impacts the following interfaces: • •
NBAP - RNC indicates BTS by NBAP: PRIVATE MESSAGES (Configuration Data) about licence and subfeature 1 activation. Frame Protocol - BTS indicates cell’s RTWP load level to RNC using spare fields in the DCH/E-DCH Frame Protocol.
Impact on network management tools The RAN3263: Enhanced Power Control feature impacts network management tools as follows: •
BTS Site Manager: –
•
BTSSM shows information that RNC license is needed in case of feature activation trial.
RNC Element Manager –
RNC EM supports the RAN3263 feature activation with parameters.
Impact on system performance and capacity The RAN3263: Enhanced Power Control feature impacts system performance as follows: •
•
The feature helps to handle the cell load in cases when the RTWP load is high. When the RTWP load is high or in overload states, the feature adjusts SIR-targets to decrease RTWP. Overall cell performance is better compared to the situation when the feature is not used. When the measured RTWP load is normal, there still might be some positive impacts to system performance due to subfeatures 2 and 3.
The RAN3263: Enhanced Power Control feature impacts system capacity as follows: •
34
The cell is able to perform closer to the theoretical HSUPA pole capacity when the cell is in RTWP overload state. The change is visible with traffic mix, which has multiple UEs and data bursts with variable burst sizes and transmission speeds.

2.6 RAN3341: Guaranteed Voice Calls in High Load Benefits, functionality, system impact, reference data of the feature. The RAN3341 Guaranteed Voice Calls in High Load introduces prioritization of Voice real time (RT) traffic over high speed downlink packet access/high speed packet access (HSDPA/HSPA) non-real time (NRT) traffic when downlink (DL) spreading codes are seen as a limitation during Admission control. This improves voice call success rate in high loaded cells.
2.6.1 RAN3341 benefits The RAN3341 Guaranteed Voice Calls in High Load feature provides the following benefit: •
•

2.6.2 RAN3341 functional description
DRAFT VERSION
In case of non-Fractional Dedicated Physical Channel User Equipment (FDPCH UEs) or if FDPCH is not enabled in the network, the signaling radio bearer (SRB) is mapped to the dedicated traffic channel (DCH), which would consume separate spreading code in the downlink. In a highly loaded cell with high number of non-FDPCH UEs, the downlink spreading codes congestion could lead to Voice call Setup failures (RAB_STP_FAIL_CS_VOICE_AS_COD). In such cases, voice calls are admitted into the system by prioritizing them over non-FDPCH HSDPA/HSPA NRT. Up to two such nonFDPCH HSDPA/HSPA radio bearers (RBs) are released to accommodate the AMR voice call.

Note: If NRT-over-NRT is needed, this functionality is provided by the RAN3110: HSPA Queuing and Resource Rotation with QoS.

2.7 RAN3110: HSPA Queuing and Resource Rotation with QoS
DRAFT VERSION
Benefits, functionality, system impact, reference data of the feature. The RAN3110: HSPA Queuing and Resource Rotation with QoS feature introduces the HSPA Queuing and NRT-over-NRT functionalities to the queuing and the scheduling of the resources request for the HSPA and HSDPA allocations in the CELL_DCH state. During HSPA congestion, a high-priority user requesting HSPA resources can bypass a low-priority user in queue. QoS-based resource rotation that refers to NRT-over-NRT enables operator to rotate the resources between all HSPA users or to favour the highpriority users.
2.7.1 RAN3110 benefits The RAN3110: HSPA Queuing and Resource Rotation with QoS feature provides: • • •
priority access to HSPA resources for high-priority users. the possibility to guarantee HSPA resources for high-priority or authorized users. the possibility to rotate HSPA resources between all HSPA users, so higher HSPA data rates could be offered.
2.7.2 RAN3110 functional description The RAN3110: HSPA Queuing and Resource Rotation with QoS feature introduces QoSbased resource allocation queuing and scheduling for HSPA and HSDPA users. HSPA queuing In current system implementation, access to HSPA is admitted without checking QoS priorities. After allocating the HSPA resources, the RAN1262: QoS Aware HSPA Scheduler feature enables taking the QoS priorities into account when scheduling the data packets. The RAN3110: HSPA Queuing and Resource Rotation with QoS feature provides QoS-based prioritization to admission control of HSPA resources. With the RAN3110 feature, higher priority HSPA users can bypass the lower priority users in the admission queue. RNC triggers HSPA queuing when a resource allocation request for NRT service mapped to HSPA transport channels (DCH/HS-DSCH or E-DCH/HS-DSCH) arrives, or when HSPA resource rotation cannot find suitable target for HSPA NRT over NRT. The order of resource allocation is based on priorities defined with the QoSPriorityMapping parameter. In case of equal priorities, HSPA resources are allocated according to queuing time - oldest requests first. When the policy for priority-based scheduling is configured to be based on allocation and retention priority (ARP), the queuing priorities are based on ARP level (the highest priority first) and the queuing time (the longest queuing time first). Priority-based scheduling policy is defined with the PBSPolicy parameter. At maximum, users are queued for HSPA resources for 25% of the time specified with the CrQueuingTimeUL RNPS parameter. After that time, RNC tries to allocate all possible configurations (HSPA, DCH/HS-DSCH, DCH x/x).

Resource rotation With the RAN3110: HSPA Queuing and Resource Rotation with QoS feature, new HSPA resource requests are managed according to their QoS priority. In case of congestion for HSPA resources new HSPA capacity request may trigger release of an existing HSPA user. Operator can choose between the following approaches applied during the HSPA congestion: •

•
Favor the highest priority users and always keep them connected. This enables operator to guarantee the HSPA connection to authorized users. Rotate HSPA resources between users, even of the same priority. Resources can be rotated after an operator-definable timeslot finishes. This enables an operator to offer higher data rates to all HSPA users.
Operator manages HSPA resource allocation using the following parameters: • • • •

2.8 RAN3270: Interference Control in HetNet Benefits, functionality, system impact, reference data of the feature. The RAN3270: Interference Control in HetNet feature introduces means to reduce interference created by UEs in high-power cells towards low-power cells when there are cells of different sizes under one RNC, in the same network area and using the same carrier frequencies.
2.8.1 RAN3270 benefits The RAN3270: Interference Control in HetNet feature provides the following benefits: • • • •
Ensuring the highest traffic off-load by small cells. Maximizing packet data throughput and the capacity of the combined macro-small cell system. Minimizing inter-cell interference between large and small cells and helps the radio network planning with the automatic algorithms by RNC. Improving network performance both in large and in small cells.
2.8.2 RAN3270 functional description The RAN3270: Interference Control in HetNet provides the tools for radio resource management to help cope with the large transmission power difference between the high-power and low-power cells. Both the high-power and the low-power cells are

located in the same area and use the same carrier frequencies. A power difference up to 6dB is handled through radio network planning and optimization. The RAN3270 feature tackles power differences larger than 6dB. The RAN3270 feature has the following functionalities: •
DRAFT VERSION
•
•
Boosting the High Speed Dedicated Physical Control Channel (HS-DPCCH) with the Active Set Update (ASU) and the Serving Cell Change (SCC). This is needed when an UE is in soft handover between a high-power macro cell and low-power small cell where the high-power cell is high-speed packet access (HSPA) serving cell. Enabling periodic EcNo reporting for both the monitored and the detected cells. Periodic reporting for the detected cells is also applied to chained neighbor cells by the RAN3271: Optimized Neighbor Cell Processing feature. Reducing the intra-frequency inter-cell interference. This is done through the soft handover (SHO) between the high-power cell and the low-power cell by using cell individual offsets (CIO), dynamically calculated by the RNC. When the SHO is not possible, uplink data rate downgrading in the high power cell is used instead.
The RAN3720 feature focuses on low-power small cells operating in the same frequency as a nearby high-power macro cell. To allow the UE to detect the small cells and report them to the network, that is, to trigger handover, the small cells must have their own dominant area. If a small cell is fully overlapped by a macro cell, the UE needs to be close to the small cell's antenna to be able to detect the small cell. In some cases the macro cell can be so dominant that handover is not possible even if the UE is very close to the small cell's antenna. If the macro cell is very dominant, the uplink interference from the UEs attached to the macro cell can block the small cell. An interference from a UE attached to a high-power cell towards a small cell occurs when the UE uses uplink (UL) power according to the requirements of the high-power cell and when the UE is not in soft handover (SHO) with the small cell. The small cell cannot prevent it when it is not in the Active Set (AS) yet. Figure 4
Interference between large and small cells: case 1.
UEuplinkrange
ServingcellDL HS-DPCCH
Micro/Pico Macrocell
When the UE is in soft handover between a high-power cell and a low-power cell, the high-power cell is a HSPA serving cell and the uplink power control is done by the lowpower cell, there might be a problem with the UE uplink synchronization in high-power cell. The high-power BTS cannot receive the UE’s uplink transmission due to its low uplink transmission power. The uplink transmission is needed for uplink grant signaling and data transmission in general. Therefore control channel boosting is needed.

2.9 RAN2825: MOCN Capacity Assurance Benefits, functionality, system impact, reference data of the feature. The RAN2825: MOCN Capacity Assurance feature introduces R99 and HSDPA capacity split between Multi-Operator Core Network (MOCN) operators according to agreed operator share.
2.9.1 RAN2825 benefits With the RAN2825: MOCN Capacity Assurance feature MOCN operators can provide their end users planned quality of service.
2.9.2 RAN2825 functional description The RAN966: Multi-Operator Core Network (MOCN) feature enables several core network operators to be connected to the same RNC and fully share all RAN resources. The RAN2825: MOCN Capacity Assurance feature allows the sharing of R99 and HSDPA RAN resources between the MOCN sharing operators, as per the configured operator share. MOCN capacity shares are defined separately for R99 and HSDPA. The capacity split per configured operator share is applicable for the UEs in the CELL_DCH state and for the UEs on HS-FACH in the CELL_FACH state. The HSDPA capacity split is applicable only for the downlink data.
g
Note: The RAN2825: MOCN Capacity Assurance feature supports all operators configured with the RAN966: Multi-Operator Core Network feature. In each cell, RNC monitors the DL spreading code usage which indicates the R99 cell load level. When the cell load exceeds the threshold defined with the LHOresRateSC parameter, RNC enforces a capacity split between the MOCN operators according to operator shares configured with the R99OperatorId and R99OperatorWeight parameters. For operators exceeding the configured capacity share limit, R99 data calls are downgraded to lower bit rates and R99 voice calls, if possible, are handed over to 2G system. The cell-load-triggered capacity split actions are continued until the R99 cell load drops below the threshold. For HSDPA traffic, cell load is indicated by the total number of HSDPA and HS-FACH users in a cell. When the cell load exceeds the threshold defined with the HSDPAUserThreshold parameter, the BTS scheduler starts the capacity split actions

according to the operator-specific shares defined with the HSDPAOperatorId and HSDPAOperatorWeight parameters. The capacity split actions continue until the number of HSDPA users decreases below the threshold defined with the HSDPAUserHysterisis parameter. The capacity split is defined here in terms of the number of TTIs available for scheduling. The RAN2825: MOCN Capacity Assurance feature supports single and dual carrier HSDPA.
DRAFT VERSION
In case of congestion, the RAN2825: MOCN Capacity Assurance feature starts the preemption and resource rotation actions to release the resources of an existing call from an operator who exceeds his share the most for a call of an operator being under his share limit. The used share is defined based on the DL spreading code usage or HSDPA user amounts. The RAN2825: MOCN Capacity Assurance feature supports the configuration of up to 25 Public Land Mobile Network (PLMN) combinations (Mobile Country Code + Mobile Network Code). The PLMNs assigned to the operator use the operator's CN and capacity share limit in the RNC. During a CN connection establishment the selected PLMN is mapped to the operator ID, which is used for cell level DCH capacity share management and also delivered to BTS for cell level HSDPA capacity share management. In case of MOCN CA there are maximum 4 sharing operators.
2.9.3 RAN2825 system impact RAN2825: MOCN Capacity Assurance impact on impact on features, interfaces, network management tools, and system performance and capacity. Interdependencies between features The following features must be activated before activating the RAN2825: MOCN Capacity Assurance feature: • • •

RAN3110: HSPA Queuing and Resource Rotation with QoS The RAN2825 feature utilizes a subset of the resource rotation functionality of the RAN3110 feature, even if this functionality is disabled in a cell (the value of HSPANRTOVERNRTEnabled WCEL parameter is set to HSPA Queuing and HSPA NRT-over-NRT are Disabled or HSPA Queuing is Enabled). During HSDPA congestion, when HSDPA call of the operator being under his share limit cannot be admitted in the cell, RNC checks if other MOCN operators are exceeding their share. The candidate for HSDPA resource release is selected from the calls of the operator who exceeds his share the most. The rules of selection are specified by the resource rotation functionality.

WCDMA 17 Feature Descriptions and Instructions
2.10 RAN3269: Optimised HSDPA Scheduler Benefits, functionality, system impact, reference data of the feature. The RAN3269: Optimised HSDPA Scheduler feature introduces optimizations to a HSDPA (high-speed downlink packet access) scheduler that increases the TTI (Transmission Time Interval) utilization and improves downlink cell throughput and end user experience.
DRAFT VERSION
2.10.1 RAN3269 benefits The RAN3269: Optimised HSDPA Scheduler feature provides the following benefits: •
Improved downlink (DL) cell throughput and end user experience: –
•
Increased TTI utilization results in overall increased of a HSDPA cell throughput.
Reduced scheduling delay: –
A HSDPA scheduling delay is reduced due to an increased number of the parallel code multiplexed users transmitting in the same TTI.
2.10.2 RAN3269 functional description High-Speed Shared Control Channel (HS-SCCH) resource utilization improvement A single MAC-hs scheduler in FSMr3 supports maximum up to 6 cells. The number of cells per scheduler related to the RAN3269 feature remains the same after the feature is enabled. The central processing unit (CPU) load limits the maximum number of parallel code multiplexed users transmitting in same 2ms TTI to 12 even though the cells can have up to 24 configured HS-SCCH channels. After enabling the RAN3269 feature the maximum number of parallel code multiplexed users per TTI increases from 12 to 24. With the RAN3269 feature users which do not require MAC-hs/ehs PDU assembly such as retransmission, the CPC order are considered (counted as) 0 users in resource check phase. There are also users with a small MAC-hs/ehs PDU assembly. And MAC-hs tries to serve those kinds of users depending on the total number of PDUs to be assembled in the current TTI.
2.10.3 RAN3269 system impact RAN3269: Optimised HSDPA Scheduler impact on features, interfaces, network management tools, and system performance and capacity. Interdependencies between features There are no interdependencies between the RAN3269: Optimised HSDPA Scheduler feature and any other feature.

DRAFT VERSION
•
There is an improvement of performance in HSDPA call delay in case system reaches the maximum number of parallel code multiplexed users for FSMr3. The maximum number of the parallel code multiplexed users transmitting in same 2ms TTI is changed from 12 to 24. There is a cell throughput improvement in high load traffic scenario with the HSFACH users. In a lab environment we can see around 2% improvement. MAC-hs can schedule more users and buffer occupancy is small for this type of the users.

2.11 RAN3271: Optimized Neighbor Cell Processing Benefits, functionality, system impact, reference data of the feature. The RAN3271: Optimized Neighbor Cell Processing feature introduces automatic optimization of an intra-frequency neighbor cell processing for the large cells-small cells interworking, which is done in a real time. The feature provides means to manage calls and handovers in a heterogeneous radio network environment and in the environments where neighbor cells of neighbor cells could be considered target cells for handovers.

2.11.1 RAN3271 benefits The RAN3271: Optimized Neighbor Cell Processing feature provides the following benefits: • •
It facilitates the configuration of the neighbor cell relations in a high cell density area. It helps cope with the 3GPP standard limitation of maximum 32 intra-frequency cells in the neighbor cell list which is signaled from the network to the UEs.
DRAFT VERSION
2.11.2 RAN3271 functional description The RAN3271: Optimized Neighbor Cell Processing feature manages an environment where a high number of small cells exist within a small area. With the RAN3271 feature less effort is needed for optimization of the neighbor cell relations in the heterogeneous networks with a high number of small cells located in the same area as macro cells. This feature consists of : •
•
Soft handover support with the missing neighbor relations to the target cell, that is, chained neighbor cell concept. Chained neighbor cells are the cells which are defined as the ADJS (intra-frequency adjacency) neighbor cells of ADJS neighbor cells defined for a cell. ASU (Active Set Update) to Detected Set cell reported in event-triggered measurement report.
The RAN3271 feature has the following functionalities: • • • • •
intra-frequency handover to chained neighbor cell event-based Detected Set Reporting (DSR) for intra-frequency cells alarm/notification when a chained neighbor cell indicates that two or more cells out of the reported cells have the same scrambling code Active Set Update to a chained neighbor cell based on event-triggered measurement report Cell Individual Offset for 1B and 1C events for cells based on event-triggered measurement report.
Basics of chained neighbors When several cells, for example macro and small cells, are allocated in the same frequency, the maximum amount of possible neighbor cells that can be indicated to UE for measuring is 32. This causes a limitation when all small cells in same area with macro cell cannot be indicated to the UE as the neighbor cells of macro cell because the other relevant macro cells must be indicated as neighbors due to mobility and coverage reasons. The chained neighbor cell concept with Detected Set Reporting must overcome this restriction by enabling UE to report detected small cells and Radio Network Controller to identify the reported cells as chained neighbor cells for handovers.

Figure 6
WCDMA 17 Feature Descriptions and Instructions
Small cell – macro cell network.
Smallcells
Macrocells
The RAN3721 feature focuses on small cells operating in the same frequency as nearby macro cells. To allow the UE to detect a small cell and report it to the network, that is, to trigger event-based handover, the small cell needs to have its own dominance area. If a small cell is fully overlapped by a macro cell, the UE needs to be close to the small cell's antenna to be able to detect it. In some cases the macro cell can be so dominant that event 1A is not triggered even if the UE is very close to the small cell's antenna. Therefore a handover to the small cell is not possible. If the macro cell is very dominant, the uplink interference from the UEs attached to macro cell can block the small cell. The RAN3271 feature allows the network operator to define several small cells with own dominance area under macro cells and provide support for mobility and handovers between macro cells and small cells. The RNC provides counters for the missing synchronization incidents attempting to add a cell to the Active Set. This allows the network operator to identify the cases where radio link is released before synchronization happened. The counters are defined for RT (real time) and NRT (non-real time), and for both ADJS and ADJD (additional intrafrequency adjacency) cells and the chained neighbor cells. There are the following counters for the ADJS and the ADJD cells: • •
M1007C87 Missing synchronization for an ADJS or ADJD cell that was attempted to be added to Active Set for a RT radio link. M1008C88 Missing synchronization for an ADJS or ADJD cell that was attempted to be added to Active Set for a NRT radio link.
The chained neighbor concept makes it possible to find the relevant cells that are not Indicated to UE as neighbor cells to the Active Set cell. The cells set as neighbor cells to the Active Set cell are called gateway cells. Chained cells are defined then as neighbor cells to these gateway cells. The RAN3271 feature requires the Detected Set Reporting for events: 1A, 1B and 1C. Using of the chained neighbor cells in a macro cell – small cell network applies to all kind of networks despite of cell size and BTS type in case there are limitations with numbers of neighbor cell.

When finding the scrambling code, reported by UE, the RNC checks among the defined neighbor cells of the cell in the Active Set, that is, originating cell. The identification of the cell is based on reported scrambling code and on cell ID. In case the reported scrambling code was not found among defined neighbor cells, the RNC checks the chained neighbor cells.

The originating cell, for example the cell where the UE is located and from where it is reporting the SC #1 based on the DSR. As chained neighbor is used, SC #1 is found behind X’s neighbor cells 1 and 3. In case of duplicating scrambling code the Active Set Update (ASU) is not done and the alarm must be set to indicate the duplicate reported scrambling code.

2.12.2 RAN3291 functional description
68
The RAN3291: UE History for WCDMA-LTE Mobility feature enables verification whether the user has LTE subscription based on the UE history information. This functionality allows handover and redirection back to LTE also in cases where the UE has been handed over from LTE to WCDMA due to single radio voice call continuity (SRVCC), load or mobility reasons. The other methods (available in earlier releases) that are used to decide whether the UE has LTE subscription are E-UTRAN Service Handover IE sent from the core network (CN) to RNC (TS 25.413), pre-redirection information element (IE) sent from UE to RNC (TS 25.331) and indication of a CS fall back call, sent either from UE to RNC or from CN to RNC (TS 25.331 and TS 25.413). These features can be used together with the new feature to maximize LTE usage while minimizing the probability of failures. Figure 10: RNC decision logic about handover or redirection to LTE presents the RNC decision logic for allowing or rejecting the handover of redirection to LTE, if the coverage exists.

The RNC receives the UE history information from the CN in the RANAP: RELOCATION REQUEST message. If the last visited cell list in the UE history information contains a LTE cell or cells, the RNC assumes that the user has LTE subscription. If the last visited cell list does not contain LTE cells, the RNC assumes that the user does not have LTE subscription. If the user has LTE subscription, the RNC allows starting of inter-system measurements for handover to LTE and for redirection to LTE as well as blind redirection to LTE if the LTE layering is configured to be done blindly. The RNC verifies the cause of the inter-system handover from LTE to WCDMA based on the value of the cause IE which is received from the CN in the RANAP: RELOCATION REQUEST message. If the UE has been handed over to the WCDMA network from the LTE network because of coverage reasons, the RNC neither hands over nor redirects UE (with or without preceding measurements) back to the LTE network as long as the target cell of the coverage-motivated inter-system handover from LTE to WCDMA stays in the active set. Handover and redirection become possible after the target cell has been removed from the active set.

2.13 RAN3044: Uplink CoMP Benefits, functionality, system impact, reference data of the feature. The RAN3044: Uplink CoMP feature enables BTS to combine the receiver signals from the current and neighbor sectors even before softer handover. Thanks to receiver combining, there is no need to wait for the downlink UE measurements to update the active cell set.
2.13.1 RAN3044 benefits The RAN3044: Uplink CoMP feature provides the following benefits: • •
Increases uplink throughput at cell borders and reduces interference with neighboring cells. Increases the probability of successful softer HO and Serving Cell Change, especially for fast moving UEs.
2.13.2 RAN3044 functional description The RAN3044: Uplink CoMP feature introduces uplink (UL) coordinated multipoint (CoMP) transmission to BTS even before softer handovers (HO). BTS receiver combines signals from all additional antennas/links from neighbor sectors in the same local cell group. The signals are combined before UE measurements trigger an active set update. When the receiver combining starts, BTS also uses the signal-to-interference ratio (SIR) information of neighbor sector antennas/links for UL scheduling. In consequence, the UL throughput at cell boundaries and the probability of successful softer HO and serving cell change increases. This feature also reduces signal interference with neighboring cells by increasing the area of UL softer HO .

For example, if the UE has radio link at Cell 21 and BTS registers sufficient UE power in Cell 22, BTS creates a virtual RL for the UE even before the signaling from RNC arrives and receiver combining starts. At the same time, the SIR from the virtual RL is used for UL scheduling. Figure 10

2.14 RAN3274: Uplink Data Compression Benefits, functionality, system impact, reference data of the feature. The RAN3274: Uplink Data Compression feature introduces new compression for uplink (UL) data and header based on the Qualcomm proprietary uplink compression.
2.14.1 RAN3274 benefits The RAN3274: Uplink Data Compression feature provides the following benefits: •
Improved user experience: More application data can be sent with the same bandwidth, which leads to a better perceived speed of the connection and improved device battery life.
2.14.2 RAN3274 functional description The RAN3274: Uplink Data Compression (UDC) feature introduces decompression of the compressed data received from the UE in uplink (UL). The decompression is based on the proprietary compression scheme introduced by Qualcomm. The compression of uplink data reduces the total uplink data volume and thereby reduces the interference, which increaces the overall uplink capacity, improves user experience and reduces the UE battery consumption. The compression of uplink data is based on pattern matching and an entropy coding. A significant amount of redundancy exists within and across the packets received in uplink and this increases the potential for compression in the UE. A compressor and a decompressor maintain a fixed amount of memory to keep track of the repetitive patterns from the past and across packets. The UE compresses both header and payload in the uplink packets. The compressed packets are decompressed at the RNC and the base station is not impacted by the RAN3274 feature. The decompression at the RNC requires an ordered delivery of packets. It is located above the Radio Link Control (RLC) and the Packet Data Convergence Protocol (PDCP) layers. This works only with the UEs that are capable of working with the RAN3274 feature and it does not impact UEs that do not support the RAN3274 feature. The UE capability is detected through Radio Resource Control (RRC message, IE and value to be checked) signaling.

DRAFT VERSION
The RAN3279: IP Based Iu-interfaces via satellite feature introduces support for IPbased transport via satellite connections for Iu-PS, Iu-CS, Iu-BC, and Iu-PC interfaces. The satellite links are used in cases where conventional IP/Ethernet transport is not available or feasible like on islands, mountains, jungle, or any other remote areas.
3.1.1 RAN3279 Benefits End-user benefits This feature can partially eliminate end-user impacts at some point when high latency satellite transport is in use. Operator benefits This feature benefits the operator from transport network maintenance, cost optimization, and for remotely located RNCs that are connected to the Core Network via satellite connections.

4 Operability features 4.1 RAN3277: CM Parameter Streamlining
DRAFT VERSION
Benefits, requirements, functionality, system impact, and reference data of the feature. The RAN3277: CM Parameter Streamlining feature introduces the organization of the configuration management parameters of the radio network elements (NEs). The following radio network parameter metadata is analyzed and, if necessary, updated to facilitate support of the NetAct Intelligent Feature Activation (IFA) application: related features, related parameters, related functions, and controlling license keys.
4.1.1 RAN3277 benefits The RAN3277: CM Parameter Streamlining feature provides the following benefits: • • •
The feature lessens the effort for troubleshooting because of the decreased probability of wrong parameter configuration. The operators can easily select a feature and able to see, modify, and provision all of the feature’s relevant and related configuration parameters for optimization purposes. This feature lessens the consumed time in setting feature parameters that resulted to faster deployment of RNW features.
4.1.2 RAN3277 functional description The RAN3277: CM Parameter Streamlining feature provides the parameter metadata that NetAct requires to allow the IFA functions. IFA is a NetAct application that facilitates the provisioning of features within the network, and the organization of a feature’s related parameters. The RAN3277: CM Parameter Streamlining feature introduces new object model metadata, and modifies the existing object model metadata. The following are the parameter metadata that are used for the RAN3277: CM Parameter Streamlining feature: • • • • •
Related features Related parameters Description of Parameter Relationships Related Functions Controlling License Keys
Related features The Related features parameter metadata identifies the features with which a parameter is associated. A single parameter may be related to one or more RAN features, and thus, be considered a feature parameter for one or more features. Feature parameters are used to identify the set of parameters that are: •

required for the proper operation of the feature introduced by the feature modified by the feature Note: The parameter modifications are identified by a related feature only if the modifications are associated with changes to the functional aspects of the parameter such as: changes to a parameter's range; or the addition of enumerator values to an enumeration parameter. The features that change the non-functional aspects of a parameter, such as its categorization, are not identified in the related features' metadata.
Related functions The Related functions parameter metadata identifies the functional grouping of parameters (FGPs) to which a parameter belongs. A single parameter may belong to one or more FGPs. Each FGP has both a main group identifier and an optional subgroup identifier. Related parameter The Related parameters parameter metadata identifies parameters that are related to one another, particularly for the purpose of defining parameter constraints recognized as consistency check is executed during the configuration plan. The following are examples of parameter constraints that indicate a relationship between parameters: • • • • • • • •
The value of a parameter depends on the value of another related parameter. A parameter's value range depends on the value of another related parameter. A parameter's default value depends on the value of another related parameter. The multiplicity of a parameter depends on the value of another related parameter. A parameter's value is calculated based on the value of another related parameter. A parameter is considered mandatory (that is, a value must be supplied during object creation) based on the value of another related parameter. A parameter must not be configured based on the value of another related parameter. A parameter's value is composed from the value of other related parameters.
Description of parameter relationships The Description of Parameter Relationships parameter metadata provides an operatorvisible description of the relationship between parameters. This information is used to formulate the object model constraints that are verified during configuration plan validation. Controlling license keys The Controlling license keys parameter metadata indicates any license keys that are required to be in place in order for a particular parameter value to be read or modified. This metadata is formulated as a logical expression that can make use of logical operators (such as AND and OR operations) and groupings (using the parenthesis). If the Controlling license key expression evaluates to false, the associated parameter's value is not uploaded by the NE to the management system. Additionally, the parameter's value cannot be modified by the operator.

DRAFT VERSION
Benefits, requirements, functionality, system impact, and reference data. The RAN3248: BTS Embedded Power Meter for Energy Efficiency Monitoring feature introduces new software to support power metering function available with the new hardware to monitor the power consumption of the RF module.
5.1.1 RAN3248 benefits The RAN3248: BTS Embedded Power Meter for Energy Efficiency Monitoring feature enables the operators to monitor the power consumption from RF modules, and system modules, which enhanced power management and optimization of a particular site.
5.1.2 RAN3248 functional description
Issue: 01A DRAFT
The RAN3248: BTS Embedded Power Meter for Energy Efficiency Monitoring feature introduces a new hardware called power meter, which is embedded in the BTS hardware's RF module. The power meter is capable of measuring power consumption in DC voltage and amperage. New counters within the M5008 measurements are created that are based on the reports from the power meter in RFs and static values in system modules. Power reports and counters are viewed in the BTS site manager (BTSSM), while only counters are collected in NetAct. The power meter function is available in RF modules that have embedded power meter. Only static values are provided for system modules that do not have energy meter hardware. RAN3248 reporting mechanism Figure 17: RAN3248 reporting mechanism describes how the power consumption is reported and viewed in BTSSM and NetAct.

Power meter A power meter is embedded in the RF modules, and it measures the power consumption in voltage (V) and amperage (A) of RF (with RRH) for every one-minute. The measured values are reported to the Operations, Administrations and Maintenance (OAM). The OAM uses these measured values to create counters and power reports to the BTSSM. OAM The OAM calculates the measured values reported by the power meter embedded in the RFs. The OAM sends the calculated counters in kilowatt-hour (kWh) to the BTSSM and to NetAct via RNC and OMS. The measured values are calculated separately by the OAM for system modules, and RFs, and the entire BTS. The OAM calculates the following counters:

Energy consumption in all RFs: The OAM sums up the energy consumption in all radio modules (with RRH) with power meter on-board in the BTS over the whole measurement period duration. This is obtained by sampling with a predefined sampling period and summing the samples. Note: In case of RF sharing, the RF value is calculated only for the master RAT. At the same time, non-shared RFs are always reported to the RAT to which they belong.

Note: Measurements are done only for RFs which have power meter on-board. In case of having different RFs, (with and without power meter) in BTS, counter includes only the values from RFs with power meter. •

Energy consumption in all system modules: The OAM sums up the energy consumption in all system modules in the BTS over the whole measurement period duration. This is obtained by sampling with a predefined sampling period and summing the samples. Note: Static values are used for all FSM-r3 and FSM-r2 (in case of FSM-r3 + FSM-r2).

Energy consumption for the entire BTS: The OAM sums up the energy consumption in the entire BTS over the whole measurement period duration. This is obtained by sampling with a predefined sampling period and summing the samples. Note: In case of RF sharing, the RF value is calculated only for the master RAT. At the same time, non-shared RFs are always reported to the RAT to which they belong. Note: Measurements are done only for RFs which have power meter on-board. In case of having different RFs, (with and without power meter) in BTS, counter includes only the values from RFs with power meter. Static values are used for all FSM-r3 and FSM-r2 (in case of FSM-r3 + FSM-r2).
BTSSM The BTSSM receives the calculated power reports from the OAM, and displays the measured voltage (V) and power (W) of the RF modules. The power report is updated according to the new reports received from the OAM for each one minute with the information of the hardware. The first power consumption report is available when the BTS reaches the configuration state. NetAct NetAct also receives the counters from the OAM via RNC and OMS. Counters that are used for KPI report are stored and viewed in NetAct. Supported hardware This feature is applicable for RF modules with RRH that has the supported power meter hardware on board. The RF sharing is also supported by this feature. The reported values of shared RFs are displayed only in the master radio access technology (RAT).

All logs are collected in the Layer3 Data Collector (L3DC), which is Megaplexer (L3DC) tool for the BTS, and Megamon (L3DC) tool for the RNC. The monitored data is retrieved and analyzed in IMSImon3G. For more information, see TSS IMSIMon3G solution description in NOLS. The RAN2861: UE Tracing Support in BTS feature requires the license activation of the RAN2930: IMSI-based Call Monitoring and RAN2973: Enhanced IMSI Based Call Monitoring features. For more information, see the following documents: •
DRAFT VERSION
•
RAN2930: IMSI-based Call Monitoring RAN2973: Enhanced IMSI Based Call Monitoring
The Megaplexer (L3DC) tool must be configured first in the BTS. Operators must configure the Megaplexer's IP address, port number, and trace contents using the BTS site manager (BTSSM). For more information, see Activating RAN2861: UE Tracing Support in BTS. The BTS sends the capability indication message to the RNC. The capability indication is determined in the BTS based on the parameters received from the BTSOM. The RNC receives the message and the call trace information is included once tracing is started in Megamon (L3DC) tool. The call trace information includes the radio link (RL) setup request or RL reconfiguration prepare message. The information in the RL message indicates the particular IMSI to be traced. The particular IMSI must be configured in Megamon (L3DC) tool to be able to trace. The list of IMSIs to be traced must be configured in the L3DC/Megamon tool. The configuration procedure is included in Activating RAN2930: IMSI-based Call Monitoring. The operator can analyze the collected call logs through the L3DA/Emil tool. The call logs are retrieved from the data collector and are decoded through the L3DA/Emil tool. For more information, see L3DA/Emil tool product description in NOLS. Active alarms are seen in NetAct when the connections between L3DC and the BTS are interrupted. The BTS sets the 7652 BASE STATION NOTIFICATION alarm if the following scenarios are encountered: • •
L3DC is faulty. Transmission Control Protocol (TCP) connection is interrupted.
The L3DA/Emil tool user is informed by a message in case that L3DA/Emil tool is unable to receive data from the L3DC during the retrieval of the call logs. The BTS stops the UE log tracing in the following scenarios: • • • • • • •
The last radio link of the specific UE is deleted. The radio link reconfiguration prepare message is received with call trace information filled with a Disabled value. The reset request procedure message is triggered from the RNC. The Iub link is disconnected. A cell with an enabled Trace UE is deleted. The BTS hardware is reset. The TCP connection with the Megaplexer is interrupted.

DRAFT VERSION
The RAN3298: Support Max 32 PS Core Elements in RNC feature increases the maximum number of PS core network elements supported by RNC from 16 to 32.
6.1.1 RAN3298 benefits The RAN3298: Support Max 32 PS Core Elements in RNC feature provides the following benefits: •
•
It ensures better operational flexibility and increased network capacity by allowing more nodes into one core network (CN) pool. This is beneficial in case of a multioperator radio access network (MORAN) where several network operators connect their core elements to the same radio network controller (RNC). The network is more robust and resilient thanks to properly distributed load across more nodes.
6.1.2 RAN3298 functional description Feature overview The RAN3298: Support Max 32 PS Core Elements in RNC feature increases the maximum number of links towards the packet core network nodes supported by RNC from 16 to 32. The support of maximum 32 PS core network elements is provided in all the RNC HW capacity steps. Only the maximum number of PS core network elements is modified. Other capacity figures remain unchanged. The maximum number of CS core network elements supported by RNC remains 16. License operations To enable configuration of more than 16, and up to 32 Iu-PS managed objects (MOs), the RAN3298 feature license must exist, and its state must be set to ON. The RAN3298 feature license name is SupportMax32PSCoreElementsInRNC and the feature code is 0000019734. After the license becomes expired, removed, or its state is set to OFF, the RAN3298 feature allows for continued use of all previously configured Iu-PS MOs (including those exceeding 16). All of the already configured Iu-PS MOs are still workable, and can be modified or removed. However, it is disallowed to create another Iu-PS until the license becomes valid, or the total Iu-PS MOs number is less than 16.

7.2 RAN3067: Flexible HSDPA Carriers Allocation Benefits, functionality, system impact, reference data of the feature The RAN3067: Flexible HSDPA Carriers Allocation feature enables large downlink carrier aggregation, that is Dual Carrier/Dual Band HSPA configurations without the need for sector-based baseband pooling.
7.2.1 RAN3067 benefits The RAN3067: Flexible HSDPA Carriers Allocation feature enables large carrier aggregation, that is Dual Band / Dual Carrier HSPA configurations without the need for sector-based pooling in pure FSMF configurations. Carrier aggregation is supported between local cell groups, resulting in the best possible uplink performance with softer handover and interference cancellation between the cells being enabled. RAN3067: Flexible HSDPA Carriers Allocation also reduces the baseband resource need (compared to sector pooling) required for soft handover between the sector pools.
7.2.2 RAN3067 functional description The current HSPA carrier aggregation implementation requires that the cells participating in the carrier aggregation are processed in the same MAC-hs instance (same LCG and HSPA schedulers). The Local Cell Group (LCG) capacity has required sector pooling to be used in configurations with multiple LCGs. RAN3067 adds the support of carrier aggregation between multiple MAC-hs instances. The feature is enabled by the high speed low latency communication (SRIO) available in the FSMF Flexi Multiradio System Module architecture. Since the MAC-hs limitation is removed, the LCGs can be allocated as per frequency layer, enabling multiple LCGs to process UEs from the same sector while supporting carrier aggregation. FSMF supports SRIO between system modules, therefore the LCGs can be mapped between different system modules and still maintain the carrier aggregation. Uplink carrier aggregation is supported within a LCG. Sector pooling-based mapping: •

Each sector has its own LCG, and no softer handovers between the cells are supported. With RAN3067, the mapping can be done in multiple ways. An example with two LCG mapping: • •
LCG1: 2+2+2 LCG2: 2+2+2
DRAFT VERSION
No new BTS configurations are introduced with this feature, except for the possibility to pool cells and LCGs in a more efficient way than before. While this feature is activated and new configuration is used, DC-HSDPA users consume part of the secondary pool resources. Additional resource usage is taken into use in the RNC. RAN3067 supports softer handover with interference cancellation between the sectors where carrier aggregation is supported, which improves uplink performance.
7.2.3 RAN3067 system impact RAN3067: Flexible HSDPA Carriers Allocation impact on features, interfaces, network management tools, and system performance and capacity. Interdependencies between features RAN3067:Flexible HSDPA Carriers Allocation makes it possible to use DC/DB-HSDPA with frequency based pooling BTS configuration. Impact on interfaces New IE: Secondary HSDPA User Weight Info is introduced to the NBAP message: NBAP: PRIVATE MESSAGE (Capability Indication) . Impact on network management tools The RAN3067:Flexible HSDPA Carriers Allocation feature has no impact on network management tools. Impact on system performance and capacity •
