Study And Application Of Service Process Model In Model-Driven Service Creation Technology

Model Driven Architecture (MDA) is the next generation software development methodology. Model-driven service creation technology applies the concept of MDA to service creation, and makes application-level reuse of telecommunication services possible, and also enhances portability and development efficiency, in which the process model plays a key role.Firstly, telecommunication service process modeling is studied. By analyzing the key concepts involved in telecommunication service process, one approach for telecommunication service process modeling is proposed. This approach uses event-driven mechanism and data-transfer mechanism to combine actions, events and service data to describe a service logic based on UML activity diagram extension, so that service logic can make response to asynchronous events from network and transfer the service data correctly, and it meets the requirement of telecommunication service process modeling. The discussion focuses on UML activity diagram extension, model description of event-driven mechanism and data-transfer mechanism. Secondly, the application of telecommunication service process model in real service creation is studied. Through in-depth analysis of the features of Convergent Service Platform, the service creation based on service process model in Convergent Service Platform is implemented. Finally, by using a service creation example, the correctness and validity of the service process modeling approach and the application of service process model in service creation are verified.
