| Currently, the national full-service telecommunications industry has entered implementation stage. With the completion of the restructuring and the building new competitive advantages, the telecommunications companies also push great sights on the future development potential of emerging markets strategy. Providing personalized information services for family-oriented customers is becoming a critical direction of China Mobile's business in the full-time business period. For now, Family information can be used as the starting point to develop home market, which is the need of absorption and development mobile users, also to adapt and meet the need of social information development, and which are the effective means of finding a new blue ocean, improving operational efficiency and increasing revenue For China Mobile. Under the current definition of the industry, family information is a platform setting the established control networks and multimedia information in one by wireless method. Family information is a system which realized the sharing of data and multimedia information and the interconnect and management of information equipment, communications equipment, entertainment equipment, household appliances, automation Equipment, lighting equipment, security (surveillance) device, the hot water tables and some other household equipment. And this definition is for a mature, comprehensive family information system.3G network can be carried out richer data services for the family because of its high bandwidth and high-speed characteristics.3G cinema is a branch of family information, which is mainly to meet the entertainment needs of demand for household products.3G cinema is to supplement the vacancy of current film market through the home theater.In this paper, the booming family information services are present as the background; we begin the study of 3G family cinema system. Firstly, according to the development trend of family business and understanding of 3G cinema products, the function of 3G cinema system are analyzed. Secondly, the overall design of 3G cinema system is introduced, including the function of the system structure, interface structure, system architecture and typical operating flow. During introducing the system architecture, modular design is introduced in accordance with the hierarchy relations of the system.Subsequently, the MBMS (Multimedia Broadcast Multicast Service) Module, the terminal module and the BSFGate (Bootstrapping Server Function Gate) module are presented in detail as a core module example in the system. In this section, the functions and locations of the modules for the three core modules are analyzed. The modules'detail design is introduced, including the system function structure, the modules' software structure. Then, the service flowchart as well as the class design is described. And the BSFGate module is introduced in detail. BSFGate module design and implemented the authentication process based on GBA (Generic Bootstrapping Architecture), using Java NIO (New IO) technology and the Diameter protocol to complete the communication between NAF (Network Application Function) and BSF (Bootstrapping Server Function) which are two network elements of GBA structure. BSFGate module has a certain versatility, which can be reused in other family information projects. At the same time, it refers to the various reference design patterns and technologies related to the module, such as EJB3.0 (Enterprise Java Bean3.0), JMX (Java Management Extensions), GBA and the Diameter protocol.In the end, the functions which need to be further explored as well as the prospects of the 3G cinema platform in the future are discussed. |
