Chapter 3 Installation Requirements
3.1 Introduction to the BSC6900
The BSC6900 is an important network element of the Huawei Single RAN solution. It adopts the industry-leading multiple radio access technologies, IP transmission mode, and modular design. In addition, it is integrated with the functions of the UMTS BSC6900 and GSM BSC, thus efficiently maintaining the trend of multi-RAT convergence in the mobile network.
The BSC6900 can be flexibly configured as a BSC6900 GSM, BSC6900 UMTS, or BSC6900 GU as required in different networks. The BSC6900 in independent mode refers to the BSC6900 GSM or the BSC6900 UMTS whereas the BSC6900 in integrated mode refers to the BSC6900 GU.
The BSC6900 GSM, in compliance with the 3GPP R6, operates as an independent NE to access the GSM network and performs the functions of the GSM BSC. With the support of EDGE+, the BSC6900 GSM can be upgraded to the BSC6900 GU through addition of UMTS boards and software upgrade.
The BSC6900 GU operates as an independent NE to access the GSM&UMTS network and integrates the functions of the GSM BSC and the UMTS BSC6900. When the BSC6900 GU accesses the GSM network, the 3GPP R6 applies; when the BSC6900 GU accesses the UMTS network, the 3GPP R7 applies.
The BSC6900 UMTS, in compliance with the 3GPP R7, operates as an independent NE to access the UMTS network and performs the functions of the UMTS BSC6900.
The following figure shows the BSC6900
