Base Station Controller (BSC)

Base Station Controller (BSC) - The BSC controls multiple BTSs. It handles allocation of radio channels, frequency administration, power and signal measurements from the MS, and handovers from one BTS to another (if both BTSs are controlled by the same BSC). A BSC also functions as a “funneler”. It reduces the number of connections to the Mobile Switching Center (MSC) and allows for higher capacity connections to the MSC.
A BSC my be collocated with a BTS or it may be geographically separate. It may even be collocated with the Mobile Switching Center (MSC).
*The interface between the BTS and the BSC is known as the Abis Interface
*The Base Transceiver Station (BTS) and the Base Station Controller (BSC) together make up the Base Station System (BSS).
