scope:
The use and general aspects of the Base Station Controller (BSC) to Base Station Transceiver (BTS) interface (the A-bis interface) are given in GSM 08.51.
The present document specifies the general structure of layer 3 and traffic management procedures and messages used on the A-bis interface to support signalling procedures as defined in GSM 04.08. Support for Location Services (LCS) related signalling, as defined in GSM 03.71, is also included. GSM 03.71 identifies new A-bis signalling to support BTS-embedded Type B LMUs as well as standalone, Type B LMUs. The standalone Type B LMU supports the layer 1 and 2 signalling for the A-bis as well as the Location Service message defined in this specification.
Network management procedures and messages for the A-bis interface are defined in GSM 08.59.
The functional split between BSC and BTS is defined in GSM 08.52. The procedures and messages required to support this split are defined in detail in this TS.
