Research On Number Portability Technology Of Mobile Communication Network

Number portability service is a global trend of development of the telecommunications industry, conducive to effective use of numbering resources to facilitate the consumers to use and enhance the competitiveness of enterprises. The implementation of number portability foreign main reason is that it can bring the country's overall economic net great. Some countries and regions in the calculation of costs and benefits of the results have in common is much higher than the cost of benefits. Social benefits in the following three aspects:more benefit for consumers, code number is conducive to resource conservation, conducive to the development of the telecommunications industry.Has been completed in the current restructuring of the domestic mobile telecommunications market, China Mobile still holds absolute dominance. China Telecom can use the "number portability" fight with China Mobile and China Unicom for more customers, expand market share. If the Government of the non-dominant operators, one-way asymmetric regulation to implement number portability, So for China Telecom, is more good than harm, you can get more stock of users of other operators. In this paper, pilot experiments currently number portability environment, the study of number portability service. Describes the international background of number portability, number portability in a foreign country described the development, through the analysis to determine the number portability for the communications industry and the community as a whole has a positive significance.The Ministry of Industry and Information Technology in China to promote the work of number portability in the context of the pilot, according to the Ministry of the overall technical program, combined with the existing network of China Telecom, the actual situation, the number portability service technology implementations have been studied, mainly including the overall network architecture, business systems transformation program operators, the business functional requirements technical requirements and equipment.Describes the overall technical implementation, this paper on number portability business process analysis and further a clear description. Business processes, including voice, short messaging and multimedia messaging business process flow, this scene from a variety of business processes and definitions given in the specification.To further elaborate the key number portability business involves technology ENUM (Telephone Number Mapping), in a later section of this ENUM technology is explained and analyzed. Including ENUM technology generation, technology, theory and application.In the last article on the current status of China's number portability brief analysis of business development for a bold prediction.
