【摘要】 随着社会发展和经济增长,人们对通信的要求也越来越高。然而在煤炭行业中,通信的发展却是举步维艰。正是由于煤炭行业当前应用的通信系统技术比较落后,直接或间接地导致了各种各样的矿难发生。因此,我们有必要开发一套新型的煤矿专用通信系统,保证煤矿安全高效的生产。针对目前煤炭行业通信系统的不足,本方案开发了一套基于TD-SCDMA的煤炭专网。TD-SCDMA是我国自主知识产权的、获得国际电信联盟(ITU)批准的国际通信标准。TD-SCDMA专网既能够全面提高煤炭行业信息化的应用程度,又可以满足地面各方面的通信需求,为生产生活带来便利。本文将重点研究基于TD-SCDMA煤炭专网设备TDR100中,与核心网PS域SGSN相关的SM(会话管理)在其中应用的方案设计——PDP上下文的两个激活过程:UE发起的PDP上下文激活,和UE发起的二次激活。本文首先完成了整个专网的系统方案设计,同时给出了SM模块两个激活过程的详细流程,设计出了两个激活流程的软件功能模块实现和处理流程。详细的描述了从方案设计到流程实现以及软件功能模块设计等项目实现过程。最后通过对其进行软件的开发和移植,以及硬件上的测试和调试,实现用户正常的PDP一次和二次激活,使得用户能在煤矿特殊性的生产环境下正常打开手机网页和发送Email,从而真正实现基于TD-SCDMA的煤炭专网。更多还原

【Abstract】 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.更多还原
