Foreword

BSC6900&6910, as a critical network element (NE) in the

Huawei SingleRAN solution, adopts the advanced multiple

radio access technologies (RATs), IP transmission mode, and

modular structure.

As the BSC is widely used, it is necessary to introduce its new

hardware and features on new version V900R015. Upon

completion of this course, you will be able to know the

GSM&UMTS V900R014 – V900R015 Delta for hardware of the

BSC6900&BSC6910.

ESAUa Board

An ESAUa board collects and pre-processes the data reported by NEs. The

ESAUa board then uploads the pre-processed data to the M2000 for

analysis. The Nastar collects and analyzes the data reported by the ESAUa

board on the M2000 side. The functions of the ESAUa board are as follows:

Manages data pre-processing tasks based on the MML commands issued by Nastar.

Pre-processes the data reported by NEs (filters and collects data reported by NEs

based on Nastar task rules).

Uploads the pre-processed data to the Nastar through the M2000 for service

analysis.

BSC6910 UMTS Configuration Principles

The UMTS dimensioning principles of BSC6910 is basically the same as BSC6900.

The only difference is that the dimension of an SPUb board and DPUe board is

replaced by the dimension of a EGPUa board.

The number of EGPUa boards on the CP and UP are calculated separately based on

the capability requirements of the network on the CP and UP. The following

formula is used:

Total number of EGPUa boards = Number of EGPUa boards used on the CP +

Number of EGPUa boards used on the UP + One backup EGPUa board at least +

Two EGPUa boards used for resource management.
