See also:  LCS-related TS/TR    

This TS specifies procedures and information coding that are needed to define and support the BSSAP LCS Extension (BSSAP-LE). The BSSAP-LE message set is applicable to the following GSM interfaces defined in TS 03.71:
  • Lb interface (BSC-SMLC).
  • Ls interface (MSC-SMLC).
  • Lp interface (SMLC-SMLC).
This TS defines message formats and encoding for BSSAP-LE and the particular subsets of it that are applicable to each of the above interfaces. This TS also defines the support for BSSAP-LE message transfer on each of these interfaces using CCITT and ANSI versions of SS7 MTP and SCCP. Additional requirements for the above interfaces that are applicable to BSSAP-LE are also defined - e.g. usage of BSSAP (as defined in TS 04.08 and TS 08.08) on the Lb interface.
