The BSC6900 platform is an important Network Element (NE) of Huawei Single RAN solution. It adopts the industry-leading multiple Radio Access Technologies (RATs), IP transmission mode, and modular design. In addition, it is integrated with the functions of the Radio Network Controller (RNC) and Base Station Controller (BSC), thus efficiently maintaining the trend of multi-RAT convergence in the mobile network. The BSC6900 operates as an integrated NE to access the GSM&UMTS network and integrates the functions of the GSM BSC and the UMTS RNC.

The BSC6900 software, running in the BSC6900 platform, is compatible with GSM and UMTS technologies. Nonetheless, one unique configuration and operation mode of the TOE, the BSC6900 software, is used. This mode belongs to the one obtained from the installation process. So, the configuration of the TOE according to the security features provided is always the same, independently of the technology used in operation (GSM or UMTS).

Functions of the FG2c Board

As an interface board, the FG2c board supports IP over Ethernet transmission.

The FG2c board performs the following functions:

  • Provides twelve channels over FE ports or eight channels over FE ports and four channels over GE ports
  • Provides the link aggregation function at the MAC layer
  • Provides the routing-based backup and load sharing
  • Supports the Abis, A, and Gb interfaces
