Research On The "Number Portability" Of Tianjin Mobile Subscribers

With the development of the telecommunications industry and popularization of telephone. Customers hope to get higher quality service. In recent years, with every country in the world pay much attention to the application of the "Number Portability", the area and the extent of the implementation has been further expanded.The supply of Number Portability is a complex systematic project, it involves the government's control policy, business, the administrative provisions of implementation, the technical standard of device interface, equipment development and the network reforms and upgrades f the operating enterprises. All these problems have a direct impact on the input costs that Number Portability requires.Considering that China as a great telecom country, network and user dimensions are bigness. In order to push forward the implementation of Number Portability steadily and orderly in our country, we need to carry on a existing network test in the finite regions before deciding whether to implement the Number Portability in the whole country.This design mainly based on the number, the necessity of carrying produce China mobile users to carry business needs, number study China mobile core network situation, for now nets various existing telecommunications business, including pronunciation, SMS, MMS, value-added and so on the different business different scene of business process and test method is a detailed study. Through this design solutions enable Number Portability business can realize not changing the number of cases, replace the operators, the user can choose better service. According to China's telecommunications industry status, considering the needs of TDSCDMA intellectual property protection, adopt a stage asymmetric turn nets, i.e. mobile 2gb users, Unicom 2gb / 3G users, telecommunications 2gb / 3G between users can each join the turn. Unicom 2gb / 3G users, telecommunications 2gb / 3G mobile user can join turned to 3G network, but moving 3G networks don't carry out.Through Tianjin mobile Number Portability design scheme to realize, can break operators number resources of monopoly, greatly promote operators improved network quality, improve the service level.
