In 2009, with the domestic telecom industry restructuring, the issuance of 3G licenses, China Mobile to carry out a comprehensive TD-SCDMA network construction. The face of the global financial crisis, according to the relevant requirements of expanding domestic demand, increasing infrastructure construction, promote the steady growth of the economy, combined with changes in enterprise development environment and business needs, the implementation of China Mobile Group TD development planning, Zhangjiakou mobile company has launched 3G (TD -SCDMA) network engineering construction work (hereinafter referred to as TD works). Period combined with TD recent focus on the development of mobile broadband services and to TD network deployment based on the dual-mode terminal voice services market positioning, corporate development and business sector demand, the demand for data services area. After the project is completed, users of the coverage area of ??3G data card services, mobile TV and video telephony features business services, including enhanced support HSDPA. Zhangjiakou region a total area of ??37,000 square kilometers, is divided into the dam, downstream the dam of two different natural areas, with a total population of 450 million people, of which agricultural population of 310 million people. Zhangjiakou City TD total project construction macrocell base stations 66, 62 of 2G base station sites, four new election site, station a total of 94%; building indoor coverage base station 93, the new TD indoor distribution system 41 properties points; 2 sets new RNC. Core network MSC / VLR total capacity to maintain the 353 million users unchanged, HLR total capacity remained unchanged at 3.69 million, the project will meet in December 2009 the Zhangjiakou Branch 30521erl of traffic network requirements. Of this thesis is based on existing 2G core network, wireless network, support network, network management network IP bearer network, GPRS network and other circumstances, planning and implementation of 2G network expansion 2G and 3G core network convergence, the RNC construction. In this thesis, a total of eight chapters, can be divided into four parts: the first part of the 3G market analysis, an overview of the domestic and international market development of 3G, highlight the services and functions provided by the TD-SCDMA network. The second part of Hebei Province, network status and the network size in Zhangjiakou detailed description of the design of the core network TD integration programs, traffic network structure, routing, trunk circuits and signaling link configuration, number assignment and work P carrying net. The third part of the wireless part of the TD network design. Elaborated on the wireless network overall design, RNC networking solutions, frequency planning. The fourth part of the arrangements for the TD network construction at all stages of the need to complete the task, economic and risk analysis of network construction, and the failure to exclude in the construction process are described. Issues during the work I have done to the following points: 1, learning and the development of TD and related technologies. Through the relevant survey summed up the feasibility and necessity of the Zhangjiakou construction of TD-SCDMA network. 2 to study the core network TD fusion technology program, participated in the MSC, MGW, HLR hardware and software upgrades, and suggest improvements. 3, using existing 2G wireless network coverage and data traffic flows, planning RNC networking solutions and the NODE site location. Participate the Zhangjiakou TD network equipment installation, equipment commissioning, network signal test, post-optimization.
