Research And Implementation For Mobile Information Service Center System Based On J2EE

With the development of the mobile communication network from 2.5G to 3G, along with terminals, network capacity, business applications and new technologies constantly change, the scope of operation of mobile business data from the initial Voice Services, Short Message, Multimedia Messaging Service, Colourful Rngtones, developed into more personalized business model direction. New business data pattern as the whole driving force of mobile communication, which requires operators to provide more efficient and convenient ways to the market to provide rich, convenient services.This paper combinates of "mobile information service center (MISC)" project, which taken on by BeiJing North fiberHome Technology Corporation Wuhan 3G R & D, through analyzing the actual design concepts of the project, detaily discussed the exploration of the modern large-scale distributed software system which based on the middleware software. This paper especially focuses on MISC structure, the design of software bus and workflow system.In modern large distributed software projects, how to provide external and internal open, flexible, unified interface and what strategy to protect the stability, reliability, expansionarility, flexibility, manageability and maintance of the entire system is one of the core study subjects in software field. This paper detaily researched the current most advanced J2EE middleware, and integrated the MISC project which focuses on the various components of J2EE middleware framework in the application system, especially, this paper discoursed upon detailed exposition of how to use J2EE middleware provide flexible external and internal unified interface, how to use J2EE middleware shield differences of hardware systems and operating systems and how to use the characteristics of J2EE to provide stability, reliability, expansionarility, flexibility, manageability and maintance.Software bus and workflow system are the core and soul of the project, this paper digested the software bus and workflow system of MISC structure, and detaily analysed of the software bus and workflow system model, which based onthe components and sharing of information. Software bus and workflow system are the challenge of our entire project, which ensure the components can be inserted to system frame. In other words, the software bus and workflow system are the central nervous system and the key to success and enlightening point of this project.The last part of this paper, I analyzed the SP system how to access to the MISC system and accordingly deal with. Further more, I expounded how to develop application components in MISC framework structure and how to use the software bus and workflow system.
