The Analysis And Research On Tandem Office Renovation

With the rapid development of Internet technology and digital communication technology, theusers’requirements of Telephone broadband and business is growing rapidly, the traditionaltelecommunication network has gradually exposed its limitations, a single voice service has beenunable to adapt to market demand, with the popularization of the public pay phones, marketcompetition is becoming fiercer, in order to obtain higher commercial interest, operators mustconstantly look for new business growth point.In order to provide users with a more flexible,diverse existing business and new business，meanwhile provide users a more personalized service,the integration of the traditional PSTN/ISDN network and IP network has become inevitable, andthe next generation network technology of Softswitch certainly achieved this fusion based, it cannot only meet the requirements of users，but also can provide new profit margins for the operator,become the common focus of the domestic and foreign telecommunication manufacturers andoperators and study.This article is precisely under such background, the use of soft switching technology,constructing a platform, through this platform can provide voice, data, video and other integratedservices to users, andprovide business layer open standard interface, introduce newbusiness, convenient and multi vendor equipment interworking.This article takes the Softswitch being the core of the next generation network as the basis,first briefly introduces research background, research status and thinking;And then introduces thebasic concept of the soft switch system and the next generation network and background, thegeneral description of the framework of the next generation network：The access layer, transportlayer, control layer and service layer, basic characteristics, this paper analyzes the characteristics ofNGN and the development advantages;Secondly, from the point of view of business needs,combined with the current network technology development condition, todesign and transformationof the original network planning for the Shanxi coal group, forming an existing set of relativelycomplete softswitch core network equipment;Then, a simple description of the core equipment ofthe softswitch network and its characteristics;Finally, after the relevant business of N31integrated network management platform for a series of tests, the results are: the optimized network tomeet the different needs of users more than before optimization.Exchange technique used in tandem is currently one of the models in soft exchange networktechnology. Because the load circuit switched network to the IP network can greatly save the linkcircuit resource requirements, the application of softswitch network is very suitable for backbonenetwork.
