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 DPUg Board
The DPUg board processes GSM PS services.
The DPUg board has 14 logical subsystems.
The DPUg board performs the following functions:
- Processes the PS services on up to 1,024 simultaneously active PDCHs where signals are coded in MCS9
- Processes packet links
- Detects packet faults automatically
