Td-scdma Network Construction

in 2009, along with the domestic telecommunications industry reorganization, the 3G license plate's provide, China moves carries out the TD-SCDMA network construction comprehensively. face the whole world financial crisis, according to the national expansion domestic demand, expands the infrastructural facilities, the promotion economy steady growth related request, the union enterprise development environmental variation and the service demand, carried out the Chinese migration group TD development project, the Zhangjiakou Migration Company started 3G (TD-SCDMA) the network project (hereafter referred to as the TD project) the construction work。This issue will unify TD "the short-term prioritize migration broadband business and based on the double model terminal voice feature" the market localization, according to the corporate growth and the Business agency demand, will have the data traffic demand region to carry on TD the network deployment. After the engineering construction completes, provides including enhancement data 3G characteristic service services and so on card service, handset television and videophone to the area of coverage user, supports functions and so on HSDPA.The Zhangjiakou area total area 37,000 square kilometers, divide into on the dam, the dam next two different natural regions, total population 4,500,000 people, agricultural population 310 ten thousand people. The Zhangjiakou TD project total constructs great honeycomb base depot 66, altogether 2G station site base depot 62, newly choose station site 4, altogether standing rate is 94%; Constructs indoor cover base depot 93, newly built TD indoor distribution system 41 property spots; Newly built 2 set of RNC. The core network MSC/VLR aggregate capacity maintains 353 ten thousand users is invariable, the HLR aggregate capacity maintains 369 ten thousand household invariable, this project will satisfy to December,2009 Zhangjiakou Subsidiary company 30521erl traffic load network demand.The present paper is mainly the basis existing 2G core network, the wireless net, supports the net, the net pipe network, IP situations and so on load bearing network, GPRS net, plans and implements the 2G net dilatancy,2G and the 3G core network fusion, the RNC construction。The present paper altogether 8 chapters, might divide into four parts the first part to carry on the analysis to the 3G market, has outlined the home, the international market 3G development, introduced with emphasis the TD network provided service and function.The second part carried on the detailed introduction to the Hebei Province network present situation and the Zhangjiakou network size, to design the core network TD fusion plan, the telephone traffic network structure, the routing, the trunk circuit and the signaling link disposition, the number assignment as well as the IP load bearing network.The third part carries on the design to the TD network's wireless part. Elaborated the wireless net system design, the RNC network plan, the frequency plan in detail and so on。The fourth part arranged the TD net to construct the duty which each stage needed to complete, after the analysis network construction, the economic efficiency and the risk, and the breakdown which eliminated to the engineering construction process rock row have carried on showing.In topic period I do the work has the following several points approximately:1, has carried on the study and the summary to the TD development condition and the correlation technique. Summarized Zhangjiakou through the related investigation to construct the TD network the feasibility and the necessity.2, have studied the core network TD fusion technical program, participated in MSC, MGW, the HLR software and hardware promotion, and gives the improvement comment.3rd, the use existing 2G wireless network cover situation and the data telephone traffic current capacity, has planned the RNC network plan and the NODE stand selected location.4, participated in the Zhangjiakou TD network engineering facilities installment, the equipment accent measuring that the network signal testing, the later period optimized and so on work.
