The Research Of Value-Added Service Development In Telecom Based On ISAG And J2EE

Parlay/ParlayX has been accepted widely by the telecom community for its opening, extensibility and independence. Most telecom operators have designed and deployed the Integrated Service Access Gateway (ISAG) based on the ParlayX. Meanwihile, the J2EE platform is becoming more and more popular in the enterprise application developing, and it is necessary to research the developing method using J2EE for the telecom service based on ISAG.This paper firstly introduced the research background and related key technologies such as J2EE, Web Service, ParlayX and so on. Then this paper introduced the design and implement of China Telecom Integrated Enterprise Information Equipment (IEIE) which realized the common service such as short message, enhanced call control and so on. On the basis, the article summed up the development methods and processes for the telecome service under the J2EE platform based on the ISAG, and proposed a code generation system which can generate the common data files, the config files and the code files using the VBA, Ant task and the Velocity.In the end of this paper, author made a summary of the work of research and practice, finally, put forward the work that should be done in the next stage.
