The Study On The System Of Tianjin Mobile Full Serviceunder 3g Network

With the ongoing trend of enlargement of the mobile telecommunication user group, more and more users are dissatisfied with single voice telecommunication, short message service and the low speed of data download. They want rapid and convenient data download so that they can handle affairs at any time in anywhere. Combined with voice telecommunication and multimedia telecommunication,3G provides super-speed data transportation, data download, video conversation, the stream medium broadcasts, position service, etc. So the multi-media, intelligence, packetized have been regarded as the characteristics of 3G. Under the push of the market and the techniques, it's an inevitable trend that the mobile telecommunication will be broad-band and intelligence and carry various services.AS a traditional mobile telecommunication operator, the Tianjin mobile telecommunication Corporation owns a perfect network and lots of users. The corporation wants to utilize the current network resource and customer resources to transfer the 2G network to 3G smoothly. Using 3G to solve current network problems, the Corporation can lower the cost of network operation while it offers multi-services to users.Through to analysis the business operation of the new environmental, tianjin mobile and interpretation of the current development situation and 2G network operation and maintenance system analysis, and seeked to promote tianjin mobile whole business operation and maintenance system of key factors. From both can provide clients with quality services to meet the diverse needs, and save cost, facilitate expansion, easy maintenance etc Angle, in a broader space for clients to provide a comprehensive information service, the realization rewanding scale development.First, the paper introduces the development history of mobile communication, this paper summarized the 3G technology theory and the domestic and foreign development present situation, and the mainstream of 3G technology standards and characteristic and td-scdma outstanding advantages were expounded, Then according to tianjin mobile network present situation, from initial arrangement principles and hybrid network strategy proposed in terms of tianjin mobile 3G construction ideas and network architecture.Secondly, the switching of core network and GPRS networks, network of analyzing the present situations, and further analysis of the various aspects to core network development brings challenges, enumerate restricts the development of core network critical problems and put forward by introducing innovative MSC Pool, high-capacity distributed HLR etc advanced equipment and network strategy for key problems solved, and optimize for subsequent engineering construction maintenance and brothers provincial company offer valuable experience of engineering construction.Finally, with China mobile td-scdma of tianjin core network reconstruction project as an example, introduces in detail the construction process and the organizational rules, and combined with the local actual conditions to develop engineering construction scheme, for in the future construction and operation and maintenance offer valuable experience. Meanwhile, aiming at the tianjin billing backup analysis system, the deficiencies of 3G backup analysis system was reformed and the optimization, by establishing TD core network integrated operation and maintenance management platform, innovation proposed facing TD network operation and maintenance method, the platform core algorithm has applied for invention patent.
