Content for TS 48.058 Word version: 18.0.0
1 Scope p. 8
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 TS 24.008 and TS 44.018. Support for Location Services (LCS) related signalling, as defined in 3GPP TS 23.071 [2a], is also included. 3GPP TS 23.071 [2a] 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 the present document.
The use and general aspects of the Base Station Controller (BSC) to Base Station Transceiver (BTS) interface (the A-bis interface) are given in TS 48.051.
Network management procedures and messages for the A-bis interface are defined in 3GPP TS 08.59.
The functional split between BSC and BTS is defined in TS 48.052. The procedures and messages required to support this split are defined in detail in the present document.
1.1 References p. 8
The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
- References are either specific (identified by date of publication, edition number, version number, etc.) or non specific.
- For a specific reference, subsequent revisions do not apply.
