Abstract

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 3GPP TS 04.08. Also includes support for Location Services (LCS) related signalling, as defined in 3GPP TS 03.71. 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.
