Abstract

Telecommunication services are provided as the joint effort of components, which collaborate in order to achieve the goal(s) of the service. UML2.0 collaborations can be used to model services. Furthermore, they allow services to be described modularly and incrementally, since collaborations can be composed of subordinate collaborations. For such an approach to work, it is necessary to capture the exact dependencies between the subordinate collaborations. This paper presents the results of an experiment on using Use Case Maps (UCMs) for describing those dependencies, and for synthesizing the state-machine behaviour of service components from the joint information provided by the UML collaborations and the UCM diagrams.
