Network Impact Report 1 Overview

1 OverviewThis chapter provides an overview of the update.

1.1 Capacity and PerformanceThis section describes how the update affects capacity and performance.

1.1.1 BSC

Compared with the specifications of BSC6900 V900R013, those of BSC6900 V900R014change when the Abis, A, and Gb interfaces use IP over FE/GE/STM-1 transmission.Table1-1 lists the changes.

Table 1-1Changes in BSC specifications

Specifications BSC6900V900R013 BSC6900V900R014

Busy hour call attempts (BHCAs) 5,900,000 11,000,000

Traffic volume (Erlangs) 24,000 45,000

Packet switched (PS) trafficthroughput (Gbit/s)

1.5 3

Number of TRXs 4096 8192

Number of packet data channels(PDCHs) that can be activated

16,384 32,768

The load sharing start threshold is decoupled from the flow control threshold in GBSS14.0. After

decoupling, load sharing optimization is triggered if the CPU load on the XPU exceeds 20%.

Therefore, after the BSC is upgraded from GBSS13.0 to GBSS14.0, the CPU load on the XPU

becomes balanced (the load on the heavy-load CPU decreases, and the load on the light-load CPU

increases). This maximizes the overall processing capability in the control plane. In addition, the

total CPU load on the XPU of the BSC may increase because load sharing optimization increases

the messages transferred between CPUs.

1.1.2 BTS

Compared with BTS3000 V100R013C00, BTS3000 V100R014C00 incorporates thefollowing changes in configuration specifications:

In time division multiplexing (TDM) networking mode, each BTS supports a maximumof 126 TRXs. This requires a transmission extension board UTRPb4 with eight E1/T1paths.

The following BTS models are involved: BTS3900 GSM, BTS3900A GSM, BTS3900LGSM, BTS3900AL GSM, and DBS3900 GSM.

In DBS3900 GSM, 21 levels of RRU3926 or 6 levels of other RRUs can be cascaded;RRU3926s and other RRUs can still be cascaded together for 6 levels.

The configuration restrictions on cascading 21 levels of RRU3926 are as follows:

A maximum of eight RRUs can be installed together to form an RRU group, and amaximum of 16 objects can be monitored by the RS485 bus per BTS.

The configuration of 21-level RRU3926 cascading is not supported if cascading isimplemented by using the common public radio interface (CPRI) panel.

If both GTMUb and UBRI are used, all 21-level cascaded RRUs must be configuredon the GTMUb.

A BTS3000 V100R014C00 configured in 21-level RRU3926 cascading mode supports a

maximum of 126 TRXs.

1.1.3 OSS

The system management, application processing, and counter storage capabilities of M2000V200R012C00 (excluding the network management components) as well as the maximumnumber of clients that can access M2000 V200R012C00 simultaneously remain unchanged.

1.2 HardwareThis section describes how the update affects hardware.

1.2.1 BSC

Compared with BSC6900 V900R013, BSC6900 V900R014 has the following new boards:

NIUa

The NIUa board provides the BSC service awareness function. This board is used withservice boards to implement priority-based service scheduling, which providesdifferentiated service quality to different services.

SAUc

The SAUa or SAUc board is required when Huawei Nastar is used. This board isconfigured in an idle slot except slots 6, 7, 12, and 13 in the Main Processing Subrack(MPS). You are advised to install it in a rear slot of the MPS.

FG2d/GOUd

As an upgrade of the FG2a/GOUa board, the FG2d/GOUd board can be used to replacethe FG2a/GOUa board when the Abis, A, and Gb interfaces use IP over FE/GEtransmission.

An FG2d/GOUd board has the following specifications:


19/175

GSM BSS




3

Supports a maximum of 1536 TRXs over the Abis interface, with each GE portsupporting a maximum of 384 TRXs.

Supports a maximum of 23,040 circuit identification codes (CICs) over the Ainterface, with each GE port supporting a maximum of 6144 CICs.

Supports data transmission at a maximum of 512 Mbit/s over the Gb interface, witheach GE port supporting data transmission at a maximum of 128 Mbit/s.

It is recommended to configure FE ports on the FG2d/GOUd board the same as FE portson the FG2a/GOUa board because the specifications of each FE port are restricted by100 MHz physical transmission bandwidth.

Compared with the FG2a/GOUa board, the FG2d/GOUd board has the followingimprovements in its processing capability:

On the Abis interface, the processing capability is 4 times the original capability.

On the A interface, the processing capability is 3.75 times the original capability.

On the Gb interface, the processing capability is 4 times the original capability.

TNUa

If all interfaces use IP transmission, the TNUa board is not required and a service boardis configured in the slot for installing the TNUa board.

1.2.2 BTS

Compared with V900R013, V900R013C01 has a new BTS model: BTS3900AL.

BTS3900AL

BTS3900AL is a new type of Huawei enhanced radio technology (HERT)-based outdoorbase station. Delivered with a power cabinet TP48600A and a battery cabinetIBBS700D/T/A, the base station controller (BSC) cabinet has the followingspecifications:

Provides a heat dissipation capability of 2200 W.

Supports up to two 650 W BBUs.

Supports up to 18 V3 RF modules, that is, nine 2 x 80 W RFUs and nine 2 x 60 WRRUs. Each cabinet provides nine RFU slots.

Allows each switch on a power distribution box to route a maximum power output of750 W to RFUs and 650 W to a BBU.

Provides a maximum power consumption of 650 W and a maximum heatconsumption of 210 W for transmission equipment in the cabinet.

Provides a 92 Ah storage battery in the cabinet to produce a short period of backuppower supply.

Compared with BTS3000 V100R013C00, BTS3000 V100R014C00 has the following new

boards:

DGLUb

The DGLUb board provides lightning
