The scope of this Technical Specification is to provide a detailed specification for interworking between the A interface
protocol and the Mobile Application Part for handling of supplementary services. The MAP interfaces of interest are the B-, C-, D- and E-interfaces.
The A-, C-, D- and E-interfaces are physical interfaces while the B-interface is an internal interface defined for
modelling purposes. Information relating to the modelling interface is not normative in this specification.
Supplementary service signalling may be passed by the MSC/VLR between the A- and E-interfaces after inter-MSC
handover. This procedure is transparent as far as supplementary services are concerned therefore interworking
concerning this process is not described in this specification.
