### BSC - Base Station Controller

A Base Station Controller (BSC) is a critical component in a cellular network, responsible for managing multiple Base Transceiver Stations (BTS). 

It handles radio resource management, inter-BTS handovers, and connecting BTSs to the Mobile Switching Center (MSC) to facilitate call processing and mobility management. 

The BSC optimizes the network's performance and ensures seamless communication between mobile users.
