The Design And Realization Of Session Management Of Coal Dedicated Network Based On TD-SCDMA

Communication level should be higher, while the social development and economic growth. However, in the coal industry, the development of communication is limping. Because of the coal industry communication system technology is relatively backward, directly or indirectly, leading to all sorts of mine disaster occurred. Therefore, it is necessary to develop a set of new coal dedicated communication system, ensure the efficient production of coal mine safety.Aiming at the shortcomings of the coal industry communication system, this scheme develops the coal dedicated network based on TD-SCDMA. TD-SCDMA is the international communication standard, which is our country independent intellectual property rights and obtains the international telecommunications union (ITU) approval. TD-SCDMA dedicated network is able to improve the level of information of coal industry and meets the various aspects of the ground communication; production and living are more and more convenience.This article mainly research the design of SM (session management) which is in connection with core nets PS domain SGSN, in TDR100 of coal dedicated communication net based on TD-SCDMA. This scheme includes two activation process of PDP context: the PDP context activation launched by MS, the PDP context secondary activation launched by MS. Firstly, this paper complete the design of system of TD-SCDMA dedicated network, and introduce the activation process of two SM modules, design two software function module of activation process,realization and processing. Detailed describe the process of design and realization, and software to process such as function module design project implementation. Finally, through the development of the software and hardware, and transplant the testing and debugging, realize PDP activation and quadratic activation, users can open mobile web pages and send the normal Email in particularity environment, for example coal mine production environment, in deed realize the coal dedicated network based on TD-SCDMA.
