Experiences of modelling and using object-oriented telecommunication service frameworks in SDL

Abstract

This paper describes experiences in using SDL and its associated tools to create telecommunication services by producing and specialising object-oriented frameworks. The chosen approach recognises the need for the rapid creation of validated telecommunication services. It introduces two stages to service creation; firstly a software expert produces a service framework, and secondly a telecommunications ‘business consultant’ who specialises the framework by means of graphical tolls to rapidly produce services. Here we focus on the underlying technology required. In particular we highlight the advantages of SDL and tools as well as issues and problems incurred.
