Abstract:

Long term trends in a telecommunication market characterizaded by a fast evolving technology, a multiplicity of providers and the presence of chains of value-added services, call for architectural frameworks which allow the introduction of new and enhanced services and their management, much faster and more efficiently than possible today. The Intelligent Network (IN) standards [Q.12xx] have been defined to meet this demand taking as a starting point the basic telephony system architectures.

This paper describes a methodology for specification, validation and implementation of IN services and service features based on SDL-92 and its object-oriented constructs [Z.100]. This methodology has been exercised in the realm of the Universal Personal Telecommunication service.

This presentation has been given during the COST-247 International Workshop on Applied Formal Methods in System Design (Maribor, Slovenia, June 17--19, 1996).
