Networks Planning And Design Of IP Multimedia Subsysterm And Application Of Heilongjiang Mobile

In recent20years, along with quick development of our country mobilecommunication, In the field of mobile, the first generation system for users to provide thebasic business, with a focus on voice and speech related business. The second generationsystem for users take bring some of the data business and more complex supplementaryservice. Now the third generation and its evolution provide users with faster data rate andthe rich and colorful multimedia business has become possible. At present, we areexperiencing rapid integration of fixed and mobile network, mobile terminal using rateincreased year by year, the mobile terminal has a large, high definition display, a built-incamera and many are used in a variety of application resources. This makes theapplication is no longer only through the user interface to exchange information with theisolated entities, peer-to-peer field application enables the sharing easier. IP multimediasubsystem (IMS) is an independent and give access to standard IP channel control systembusiness, he makes on ordinary Internet protocol terminal users use different types ofmultimedia business has become possible.This article mainly aims at the Heilongjiang subsidiary of China Mobile IMSnetwork planning and design. Including for the China Mobile IMS network technologyresearch and for the IMS technology based on unified CENTREX application. Firstintroduced the IMS development history, features, system architecture, protocol andprocess, and then introduced the Heilongjiang mobile IMS network structure, trafficmodel, planning and design, adjustment scheme, based on the network analysis of thecurrent situation, including the signaling capacity, around the city of different trafficmodels, from the long-term future business development angle, on Heilongjiang mobileIMS network for forecasting and analysis, on the program were compared and analyzed,finally determined the optimal scheme. Finally introduced the unified CENTREXbusiness scope of application, the user types, platform architecture, configurationcalculation.
