Abstract:

Model-driven service creation technology allows the reuse of application-level and enhances portability and development efficiency in telecommunication services. After analyzing the key concepts involved in telecommunication service process, a new event-driven approach for telecommunication service process modeling is proposed. This approach uses event-driven mechanism to combine actions and events to describe a service logic based on UML activity diagram extension, so that the service logic can make correct response to asynchronous events from network. This approach also meets the requirement of telecommunication service process modeling. UML activity diagram extension, model description of event-driven mechanism and executing mechanism of service process model are studied as well.

Key words: telecommunication service process, process modeling, event-driven, uml activity diagram
