Telecommunication service design support using the visual service description language STR-GR

Abstract

As we move toward an information society, telecommunications services are becoming more sophisticated and personalized. Accordingly, there is demand for technology that simplifies complex services so that even laymen can create and customize them.This paper describes the telecommunication service design support which facilitates the retrieval of existing service specifications, modification of these specifications using state transition rule (STR) based graphic representation, and verification of service interactions. The service design support provides the facility of finding out the existing services without knowing how to activate or operate them, when performing simulations.
