The Base Station System (BSS) contains two functional entities; the Base
Station Controller (BSC) and the Base Transceiver Station (BTS).
The BSC handles radio-related functions, such as handover, management of
the radio network resources, and cell configuration data. It also controls radio
frequency power levels in RBSs and MSs.
The BTS is a network component which serves one cell and is controlled
by the BSC. The BTS contains a number of transceivers. It consists of the
radio transceivers and all the digital signal processing equipment. RBS 2000
contains equipment for 1 – 3 BTSs.
