Enhanced IN for personal communications
Service mobility and the personalisation of services are main concerns of a modern telecommunication environment. In addition, cooperation among services and a simple presentation form to the end-user are of extraordinary importance as well. To fulfil these requirements, a user defined environment called Personal Services Communication Space (PSCS) is under development by the RACE II project Mobilise (R2003). This concept has to take into account all involved players and their specific requirements. The main features of PSCS are: personal mobility based on UPT, personalisation to have personal working environments for end-users, and interoperability to have effective interworking between different services offered on heterogeneous networks. The PSCS Conceptual Framework is primarily based on the Intelligent Network Conceptual Model (INCM) with extensions taken from Open Distributed Processing (ODP).
During the development process of PSCS, difficulties were encountered in composing PSCS services and services features based on IN's Global Functional Plane (GFP) concepts of Capability Set 1 (CS-1). As a result important enhancements are proposed, which are presented in this paper:
The introduction of recursion and parallelism into the concept of Service Independent Building Blocks (SIBs) to allow IN service engineering to be more object-oriented.
The introduction of domains in the GFP to be able to model the different stakeholders involved in IN services.
Even end-users and subscribers will have their own domain in the future. This idea is reflected by the notion of the PSCS Flexible Service Profile (FSP), in which end-users have their own personalised service logic.
