Abis interface in mobile system

The Abis interface in mobile systems refers to the communication link between the Base Station Controller (BSC) and the Base Transceiver Station (BTS) in a Global System for Mobile Communications (GSM) network. It is crucial for managing radio resources and facilitating the transfer of signaling and traffic data between the BTS and BSC. The Abis interface typically utilizes protocols such as A Interface for signaling and the A-bis interface for traffic. This ensures efficient management of calls and mobile services within the cellular network.
