Applying an Object-Oriented Methodology for Modeling the Universal Personal Telecommunication Service

摘要

The aim of this article is to use an object-oriented methodology for modeling an IN service,especially the UPT service.That is done by applying the OMT methodology:in the object model,we specify objects and theirs relationships in the UPT service;in the dynamic model,we provide the behaviour of the UPT service through a state diagram,and we show up interactions among objects through a registration procedure.Also,these works enable us to highlight that an IN service-behaves as a distributed application.This consists of objects, which are located in different physical en ties.
