It is necessary to transfer between entities of a Public Land Mobile Network (PLMN) information specific to the PLMN in order to deal with the specific behaviour of roaming Mobile Stations (MS)s. The Signalling System No. 7 specified by CCITT is used to transfer this information.
This TS describes the requirements for the signalling system and the procedures needed at the application level in order to fulfil these signalling needs.
Clauses 1 to 6 are related to general aspects such as terminology, mobile network configuration and other protocols required by MAP.
MAP consists of a set of MAP services which are provided to MAP service-users by a MAP service-provider. Clauses 7 to 12 of this TS describe the MAP services. Clauses 14 to 17 define the MAP protocol specification and the behaviour of service provider (protocol elements to be used to provide MAP services, mapping on to TC service primitives, abstract syntaxes, etc.). Clauses 18 to 25 describe the MAP user procedures which make use of MAP services.
