Investigation Of Network Integration And Services Integration Under The Control Of IMS

Fixed mobile convergence (FMC) is a kind of trend of the future networkdevelopment, the FMC is in a given network, in the limiting case subject to accesstechnology and user position for end users to provide a kind of ability and mechanismof business or application, for users, FMC can make the terminal different user accessnetwork to get the same service, get the same business.With the development of the times, the customer terminal of multimedia servicerequest more and more high, they hope future service more innovative, more kind, anew network core technology--IMS was born in this background. IMS isintroducedfrom the3GPP version of R5, It can not only make mobile integration with the fixednetwork to the two network, but also for fusion users commonly used voice, dataand video services.From the network level, the current network technology with network operatorsuse each are not identical and are independent of each other. To achieve the networklevel of fixed network and mobile network fusion can only put these exist alonenetwork integration has become an independent standard network. Under the controlof IMS network convergence is not completely replace the original traditionalnetwork, but the coexistence and interworking, and gradually absorb all kinds ofbusiness, eventually with the demise of traditional network and gradually evolved intoa full IMS network.From the business level, Implement business integration is provide to the userthrough the different way of access is very common business, and then develop intocomprehensive telecommunication business. The need to establish a common serviceplatform integration of real business, that business is not affected by the user accessand heterogeneous network, the realization of access independent and seamlessroaming between different networks.Implementation of fixed and mobile network convergence is the inevitable resultof the development of China Telecom network in the market economy, but also ChinaTelecom industry with the world, an important guarantee to achieve the globalizationof information.At present, the operators and equipment manufacturers believe thatIMS is the best choice to promote integration, more and more operators andmanufacturers were attracted to IMS, we have reason to believe that with thedevelopment of IMS, the concept of the next generation network in the brains ofpeople will be more clear, will be more rapid implementation, users enjoy the business in the near future will be more abundant.This paper on the background of network integration and services integrationunder the control of IMS, the purpose and significance of the research are brieflyintroduced. Analysis of the key technology of IMS and the main protocol,andthe provincial network situation analysis, in view of the existing problems,putsforward the general idea of network integration and service integration. The IMSnetwork construction for the planning and design, puts forward the configurationscheme of IMS network elements, and the IMS with the original networkintercommunication and numbering scheme for the implementation anddiscussion. On the function of IMS network are tested and analyzed. The lastargument network integration and business integration under the control of IMS iseffective.
