| With full-service era, core network technology continues to progress, continue to evolve to optimize, how to achieve FMC (Fixed Mobile Covergence, fixed network and mobile network convergence) to form the core network integration is the industry consensus. Softswitch as an intermediate means to promote network convergence will play, the role of accelerating all business operations, the development trend of the network will evolve from the Softswitch to IMS.Network convergence is the development of today’s communications industry is a basic direction is to adapt the communications market competition and reduce the cost of network operation and maintenance needs. Integration goal is to provide a unified end-user service experience, not on the means of access users and terminal type. Through integration, operators can improve asset utilization, expansion of network coverage, ease of use business to improve, expand the network of multi-service.Tianjin is a national pilot LNP areas, and are the first group to carry out the integration with the Bureau of Railway crossing work Tianjin mobile network conditions are unique, making the general organization of the IMS routing principles do not apply to the actual situation of the mobile network in Tianjin. Therefore, this paper during a rigorous reasoning, detailed test resulted in a route for moving horizon principle, the conclusion of the project organization and the Bureau of data routing configurations, has played a very good guide.Currently, the world’s major mobile operators are accelerating the process of commercial IMS network. For example, China Mobile has started on WeblMS, IMS-based high-definition service, IMS-based services such as telepresence research as the future development of technologies for IMS. Tianjin Mobile is also actively developing the IMS network, active in IMS-based network of corporate clients, family customer-related business promotion, to develop the user, making the IMS network can make the best use. |
