2.2 Capacity and Performance

2.2.1 RNC

The RNC models for RAN15.0 are BSC6900 and BSC6910.

BSC6900

 Resource optimization on the user plane and control plane

During service access, to improve the RNC reliability and utilization of resources on the control plane and user plane, the DSP for carrying user-plane services and SPU sub-system for carrying control-plane services are optimized in terms of the following aspects:

(16)

2-2 − Resource management on the control plane and user plane: Resources on the control plane and user plane are allocated based on the capacity of each SPU sub-system rather than centralized management of the MPU.

− DSP selection algorithm based on load balancing: The DSP is selected based on the actual CPU usage rather than the GBR capability consumption.

− Inter-subrack load sharing algorithm: Load sharing in the control-plane and user-plane resource pools is performed based on the physical subracks rather than the logical subracks managed by the MPU. The inter-subrack load on the user plane is calculated using the average DSP CPU usage rather than the average GBR capability consumption and average DSP CPU usage.

− The load sharing threshold for the inter-subrack user-plane resource pool is set to 50% by default so that loads are evenly allocated among the subracks.

− Resource management on the user plane does not depend on GBR admission.

 Impact on Capacity and Performance

− The CPU usage of the MPU sub-system declines.

− The DPU CPU usage slightly increases and its absolute value does not exceed 2%.

− The SPU's or DSP's CPU usage changes when the SPU or DPU and the bound MPU are installed in different physical subracks because inter-subrack load sharing is performed based on the physical subrack. If both DPUb and DPUe boards are installed in a physical subrack, the DSP loads will be evenly distributed between the DPUb and DPUe boards.

− If the DSP CPU usage is low, service access failures have no correlation with the failure of GBR capability admission.

BSC6910

The BSC6910, a new-generation BSC product, is introduced in RAN15.0. Compared with the BSC6900, the BSC6910 has a higher system capacity and improved networking capability.

 _{Improved system capacity}

RAN15.0 BSC6910 uses new cabinets, subracks, and boards to greatly improve capacity specifications, as listed in Table 2-2.

BSC6910

The BSC6910 is introduced in RAN15.0.  Cabinets

The BSC6910 uses the Huawei N68E-22 cabinet or earthquake-proof N68E-21-N cabinet. The BSC6910 cabinets are not interchangeable with the BSC6900 cabinets because each subrack in a BSC6910 cabinet is independently powered.

 _Subracks

The BSC6910 uses new-generation Platform of Advanced Radio Controller REV:b (PARCb) subracks. The PARCb subrack has a standard width of 19 inches, which complies with IEC60297. The height of each subrack is 12 U. Boards are installed on the front and rear sides of the backplane, which is positioned in the center of the subrack. The PARCb subrack provides powerful power supply and heat dissipation capabilities for the BSC6910. The PARCb subrack differs from the PARC subrack used in the BSC6900 in terms of power supply, cable layout, and heat dissipation methods. For details, see BSC6910 Hardware Description for RAN15.0.

 _Boards

For RAN15.0, BSC6910 uses the same boards as BSC6900. BSC6910 also uses additional boards exclusively.

Table 2-14 Changes in the NodeB license control modes

Feature ID License Configured on… Feature Name Change Description

None NodeB HSDPA Code If there is no HSDPA code control item in the NodeB license file, HSDPA services cannot be processed by the NodeBs under the RNC.

Before upgrading a NodeB to RAN15.0, check whether there is an HSDPA code control item in the NodeB license file. If there is no HSDPA code control item but HSDPA services are required, add the HSDPA code control item before the upgrade. Otherwise, HSDPA services cannot be established under the RNC and ALM-22217 UMTS Cell HSDPA Function Fault is reported after the upgrade.

None NodeB Power

License

A new resource item Power License (per 20W) has been added. One local cell can use multiple Power License (per 20W) resource items. This enables flexible use of power licenses. The power licenses in earlier versions can still be used in RAN15.0. The new resource item Power License (per 20W) can be used only in RAN15.0.

None NodeB UL CE

License

When the number of uplink CEs used for UE admission in a NodeB reaches 105% of the licensed value, the RNC rejects access requests of new users. This problem can be solved by increasing the number of uplink CEs.

None NodeB DL CE

License

When the number of downlink CEs used for UE admission in a NodeB reaches 105% of the licensed value, the RNC rejects access requests of new users. This problem can be solved by increasing the number of downlink CEs.

WRFD-010683

NodeB Downlink 64QAM

A new cell-level downlink 64QAM switch has been added. If the total number of cells enabled with downlink 64QAM is greater than the licensed value in the NodeB license file, reduce the number of cells enabled with downlink 64QAM or obtain sufficient licenses. Otherwise, after the NodeB is upgraded to RAN15.0, ALM-26811 Configured Capacity Limit Exceeding Licensed Limit is reported and downlink 64QAM cannot be used in some cells.

2.6 Inter-NE Interfaces

In RAN15.0, interfaces between each RNC and other NEs and between each NodeB and UEs comply with 3rd Generation Partnership Project (3GPP) Release 10 and are backward compatible with 3GPP Releases 9, 8, 7, 6, 5, 4, and 99. These interfaces are Iu, Iub, Iur, and Uu.

(32)

2-18 In addition, RAN15.0 introduces the Iur-p interface, which is a Huawei proprietary interface used in the RNC in Pool feature. The Iur-p interface is used to transmit control plane signaling between different physical RNCs.

For the impacts of each feature on these interfaces, see chapter 4 "Impacts of RAN15.0 Features on RAN14.0."

2.7 Operation and Maintenance

RAN15.0 introduces new and enhanced features and internal system optimizations. Therefore, MML commands, parameters, performance counters, alarms, events, and licenses have changed. For the impacts of each new and enhanced feature on operation and maintenance, see chapter 4 "Impacts of RAN15.0 Features on RAN14.0." The operation and maintenance changes for the RNC and NodeB are closely related to the software version. For detailed changes in a specific software version, see the following change documents in the RNC and NodeB release documentation:

 _{MML command and parameter changes}  _{Performance counter changes}

 _{Alarm changes}  _{Event changes}  _{License changes}

4 Impacts of RAN15.0 Features on RAN14.0

(New/Basic)

RAN15.0 has the following system improvements compared with RAN14.0:  _{Supports new features specified in 3GPP Release 10 (March 2012).}

4.2 WRFD-150230 DPCH Pilot Power Adjustment (New/Basic)

4.2.1 Feature Description

This is a trial feature.

When the downlink non-HSDPA transmit power in a cell is high, this feature reduces the downlink DPCH power consumption. The saved power can admit more UEs or promote HSDPA throughput.

4.2.2 System Capacity and Network Performance

System Capacity

When the downlink load in a cell is heavy, this feature reduces downlink DPCH power consumption by configuring a shorter bit length and smaller power offset for the pilot field. Ultimately, this feature reduces the power requirements of each UE in this cell. If HSDPA UEs are in the majority in this cell, the mean transmit power of the downlink DPCH carrying HSDPA UEs is estimated to decrease by 5% to 20%. The saved power can admit 5% to 10% extra UEs if non-HSPA load remains unchanged. This capacity gain is affected by the proportion of UEs processing real-time services. The higher this proportion is, the less the gain this feature provides.

Network Performance

Because the saved power can admit more UEs or increase the downlink throughput of a cell, this feature positively affects network performance as follows:

 _{When the number of UEs in a cell remains unchanged and the traffic volume in this cell is sufficient,} more power will be saved to increase downlink cell throughput.

 When potential UEs attempt to access a cell in the case of downlink power congestion, this feature increases the access success rate during busy hours.

This feature also has negative impact on network performance. If the power offset or bit length of the pilot field is reduced, SIR estimations will become less accurate and Uu-interface synchronization probability is reduced. This increases the call drop rate. Calls drops become more noticeable in lightly loaded cells.
