Rapporteur:  Mr. Andersen, Niels Peter Skov
Antecedent:  TS 09.31    
See also:  GERAN-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 43.059:
  • Lb interface (BSC-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 either ITU-T and ANSI versions of SS7 MTP or IETF M3UA/SCTP 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 24.008 and TS 48.008) on the Lb interface.
