Signalling Transport Mechanism Specification for the Base Station System - Mobile Services Switching Centre (BSS-MSC) Interface
The present document is split into two parts, clause 1-4 dealing with the MTP and clauses 5-7 dealing with the SCCP and its use.
The MTP provides a mechanism giving reliable transfer of signalling messages. Clauses 1-4 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 SCCP is used to provide a referencing mechanism to identify a particular transaction relating to for instance a particular call. Clauses 5-7 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.
