The EuroBridge Methodology for TelecommunicaUons Service Specification

Bbstmcf In designing and specifying a system that will be used to provide telecommunications services to a user population, it is important to identify all major actors involved, and their individual concerns at an early stage and to carry this knowledge through to the design and implementation of the service. Within the RACE EuroBridge pmject efforts are underway to provide a a toolkit and a unified system architecture to support designers and providers of advanced multi-media network services. In this paper, we examine the approaches taken to service specification by the Intelligent Network (IN) community and the RACE Open Services Architecture (ROSA) project . We investigate the applicability of these techniques to the specification and design of multi-media services to be hosted on the EuroBridge Service platform and apply the ROSA approach to a simple video-conference specification. We further outline how it can result iii a complete design that can be implemented on the EuroBridge Service Platform. based on the OS1 reference model, using the IS0 Development Environment (ISODE) as a starting point.
