Research On The Application Of Softswitch Technology About Mobile Communication Domain

In the high-speed mobile business development, new business demands more and more complex combination of a variety of business and be able to request more intertwined set of flexible support system. With the development of communication technology, major equipment manufacturers at home and abroad for business market demand for diverse challenges have made mobile Softswitch solution. Soft-switching technology for communications carriers to provide the technical transformation and strategic development opportunities and enhance the operator is the core competence of one of the important technical means. With the Softswitch technology gradually matured, both fixed-line operators or mobile operators, have started to test the water Softswitch applications. Softswitch technology in the first long-distance network and access to the network tandem applications, and is gradually moving towards the local access network and mobile network penetration.For existing mobile operators, will Softswitch technology into the local mobile network for the exchange of 2G network to solve problems in the provision of opportunities. This article first introduced the soft-switching technology from the many advantages, mobile Softswitch technology introduction, technical characteristics, features a detailed description. At present, the exchange of 2G mobile network equipment in the main disadvantage of small-capacity, low processing power, the large area of the engine room, there is no mechanism in areas such as disaster recovery, and the introduction of Softswitch technology to address the above issues.Second, this article on the Softswitch technology involved in the system interfaces and signaling protocols, including the MC interface, NC interface, NB interface, and so did a brief introduction. It is based on more than one interface and signaling, in order to achieve a soft switch control system with framework for the separation of the load, making Softswitch network architecture better and achieve more powerful functionality.In the understanding of the soft-switching technology on the basis of this paper Softswitch technology in Tianjin, the local mobile network and the introduction of the program for the replacement of the existing network structure optimization in detail, further illustrates the Softswitch technology in the local mobile network The introduction of the need. Tianjin Mobile in May 2006 the successful introduction of the first set of soft-exchange system and has successfully replaced the original part of the TDM switching equipment. Shows that the soft-switching technology in Tianjin, the local mobile network has been widely used, the soft-switch technology is ripe, the ability to provide business has been verified.This article also Softswitch technology in the Tianjin local network applications in the process of discovery of a number of issues sorting through these issues to deal with the ultimate soft-switching technology to reflect the actual network application.Finally, the article also based on Softswitch technology, dual-homing system for disaster recovery, and disaster recovery system for the practical application of the results described. At present, Tianjin Mobile uses the N +1 disaster recovery backup mode. At the same time, with the soft-switched networks from the application to gradually mature, soft-switching technology based on the IP voice business will be carrying the biggest bright spot. At the conclusion of this article, will also have a VOIP business outlook and a brief introduction.
