Improvement Of Service Module Of Integrated Data-Service Platform

Nowadays, Mobile operators are changing from the mobile communications specialists to mobile information specialists. With the transform of mobile operators in the role of strategy, the entire value-added services market is changing. Mobile operators have already started to integrate market and probe self-supporting service. According to the present trend, an integrated data-service platform will be the direction of the development of mobile data services. Integrated data platform (IDP) is an open, modular, standards-based platform Downwards, it provides communications capability with ISMG (Internet Short Message Gateway), MMSC (Multimedia Message Service Center), BOSS (Business & Operation Support System), WAP (Wireless Application Protocol) Gateway and other functional entities. Upwards, it provides user authentication, SMS (Short Message Service) / MMS (Multimedia Message Service) sending and editor, user management and other public functions. The main structure and the capability are on the basis of meeting existing data products. Service developers no longer need to concern about the underneath communication with other network entities, they can pay more attention to the development of service logic. In addition, the IDP will integrate parts of the basis service functions.Service systems based on IDP had been put on the commercial stage in many provinces, and users are growing steadily while service is running steadily. But with the growth of users, many problems have been found, mainly involved with the service module, function improvement and performance optimization need to be done.First, the booming mobile data services and the open architecture of mobile data networks are present as the background and the analysis of service type, service trend and service development strategy for the Operator leads to the current market demand for integrated data platform, then the background of IDP as well as the role of the users is analyzed. After that, J2EE (Java 2 Platform Enterprise Edition) and EJB (Enterprise Java Bean), the key technology in IDP development is described. Then, the system design is introduced, including the system structure, logical structure. In the end of this chapter, some problems in the old service module of IDP system are presented.In chapter two, we analyze some representative performance problems in old service module of IDP system It mostly includes two performance optimization points: Cache and SQL (Structured Query Language). For the first point, we analyze the problem and introduced a memory object caching system called MemCached, describe the deployment and application solution of server and client, including the comparations after test For the second point, we analyze and describe several ways of optimizing SQL statement, following with test data.In chapter three, we analyze some representative function problems in old service module of IDP system It mostly includes four function improvement points: Transaction function improvement by use of JTA (Java Transaction API). Open interface improvement by use of Web Services. Advanced persistence function improvement by use of EJB-QL (EJB Query Language). New terminal adaptation function solves the MMS (Multimedia Messaging Service) play problem caused by performance difference between user terminals. The specific solution details and implementation strategies are described in this part of this thesis, including some comparations between old system and new system after each optimization or improvement pointIn the end, the functions which need to be further explored as well as the prospects of the IDP platform in the future are dicussed.
