Abstract

Service Interactions in Intelligent Networks are a major obstacle to the fast and cost-efficient introduction of new telecommunication services. In this contribution, a class of service interactions are addressed that result from deficiencies of the IN infrastructure to provide to a service the necessary information to carry out its task properly. A number of requirements are estalished that remove or at least reduce these deficiencies, and a proposal is made how these requirements could be realized. In this proposal, the concept of Service Admission Control (SAC) is introduced, which is based on a session concept represented by a dynamic Session Configuration Profile (SessCoP) accessible and modifiable by IN services that may influence a call relationship (session). This SessCoP allows the IN services to gather the information needed to carry out their tasks properly, that are not provided by the messages of the signalling protocols. The application of these concepts are explained by two brief case studies. This contribution reports on work in progress.
