Study On Service Composition Of Telecom Based On Semantic Web

In the future convergent network environment, telecom services have gradually moving towards developing user-centric,convergent and intelligent services, including the original services and new services composed of variously existing services.Abviously, the latter will be the chief form in the future environment. As a result, how to exploit service composition will be the mainly problem for telecom service providers.Traditional web services can't support services'automatically and intelligently discovering, matching, executing monitor and composing because of lack of semantic description.The Semantic Web services which have advantaged ascendancy, can model user's demands and service abilities through ontology which can be achieved by computers. As a result, this paper will discuss telecom service composition based on Semantic Web.Firstly, this paper makes a brief introduction of telecom services'trend of development, and points out that the dominative form will be the composed services which can be supported by muti-service-providers. The drivable cause,the necessity of developing composed services,the working pattern and the modeling language of composing services are introduced. Then the paper generally introduces the conception and ascendancy of Semantic Web,Semantic Web service after analyzing the disadvantages of the traditional web services.Secondly, the paper researches from theory to explore the Semantic Web services technology applications web service portfolio to the feasibility. A Semantic Web service compositon framework model is designed, and the structures of implementation are detail- oriented. This model mainly consists of the telecom domain ontology, the semantic UDDI, the service execution engine.Solutions of realizing service composition are given through those modules.Finally, a telecom service composition instance is proposed to certificate the theories and fundamentals in using the semantic web to composite the services, and the result has proved the feasibility of using Semantic Web service in composing telecom service.This study provides a useful reference and a promotion of Semantic Web services composition, playing a certain role in guiding and practical significance.
