The present document is split into four parts, clauses 4 to 6 dealing with the MTP, clause 6a dealing with M3UA/SCTP, clause 7 dealing with interface functions towards higher layers and clauses 8 to 10 dealing with the SCCP and its use.
The MTP provides a mechanism giving reliable transfer of signalling messages. Clauses 4 to 7 of the present document deal with the subset of the MTP that can be used between an BSS and an MSC, which is compatible with a full MTP.
The M3UA/SCTP provides a mechanism giving reliable transfer of signalling messages over an IP network.
The SCCP is used to provide a referencing mechanism to identify a particular transaction relating to for instance a particular call. Clauses 8 to 10 identify the SCCP subset that should be used between a BSS and an MSC. The SCCP can also be used to enhance the message routing for (for instance) operations and maintenance information.
