The Study On The Evolution Of Zhang Ye GSM/GPRS Network To 3G

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 provids 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 Zhang Ye 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.The thesis considers of the Zhang Ye GSM/GPRS network scale and present condition. From wireless access network, core network, transmitting net and business operation network aspects, the thesis proceeds an conjunction with the programming and puts forward the project to solve the actual problem of the enterprise so that it can provide high quality service for users, meet the various services require, save the cost, expand network scale easily and maintenance the system conveniently. First, this thesis introduces the development of the mobile telecommunication, summarized the 3G techniques and it's actual application in domestic and overseas. The thesis also describes the outstanding advantage of 3G main technical standard and the characteristics of TD-SCDMA. Then according to the present condition of the Zhang Ye mobile GSM/GPRS network, the thesis puts forward the way of the evolution to 3G at the initial stage.Secondly, from how to make use of 2G network resource to construct 3G and realize operating each other of the 2G and 3G, the thesis puts forward the project of the wireless access network's evolution to 3G. In this part the thesis also overviews the evolution strategy according to that the 2G/3G shared the core network and designs the whole IP core network project. The thesis proceeds to reform the Zhang Ye business operation support system on the base of it's present condition.Finally, the paper analyzes the marketing strategy on the base of the market condition and compete environment in Zhang Ye, then prospects the development of the next generation network technique.
