1. With Um interface, BS8908 accomplishes terminal access and RF link transmission,
including: RF signal processing, channel coding and decoding, channel multiplexing
and de-multiplexing, measurement and reporting, power control, transmission
diversity, receiving diversity, calibration, and synchronization.
2. With Abis interface, it is connected with BSC and accomplishes the following functions:
cell management, reporting BTS measurement information, broadcasting system
messages, access control, mobility management, radio resource management, RF
signal processing, and transmission management.
3. With operating and maintenance interface, it performs system management, including:
