The Solution Design And Implementation Of Fixed Telphone Network Based IMS

After the2008reorganization of the telecommunications industry, the Chinese telecom industry, the formation of China Mobile, China Unicom, China Telecom, the three pillars of. Network integrated into the various telecom companies in focus, after the network has converged and open network architecture to provide flexible service capabilities, rich experience and low-cost building operations and maintenance functions, which have become the main concern of communication enterprises factors. Recognized as the industry’s core integration technology, IMS is the integration of communication technology and Internet technology product, it has an open standard architecture to support both fixed and mobile network access, with its provision of flexible business and operational capacity of departure, and multimedia service and operational capacity of the control, the use of its control level fusion technique that will help operators to deliver converged multimedia services, so operators to promote IMS as an important technology convergence.After nearly three years of their development of network convergence, China Unicom, China Telecom’s entire business operations done in full swing, with the exception of China Mobile in the state under the influence of asymmetric regulation policy, combined with its fixed-line operator, China Tietong has three years in the joint development stage, it was not fully integrated China Tietong, the true meaning of the entire business operations, which must contain its development played a role. China Mobile is no fixed telephone network, the development of the whole business must rely on China Tietong’s fixed telephone network.The authors work from the perspective of China Tietong to present the communications operator’s IMS technology as the core focus, focus on the fixed telephone network into the IMS network in technical solutions. This article begins with an overview of the IMS standardization process, protocol and structure, and thus the study of China mobile CM-IMS solutions, focusing on interoperability and the routing scheme from the different scenarios of fixed access solutions, and analyzes the problems that may occur in real time fax service The implementation of the program; and in the fourth chapter focuses on access to IMS network solutions China Tietong.This article is divided into five chapters. In this paper, the theory with practice, analysis and demonstration programs and other than the election method.The first chapter, Introduction, by analyzing the reorganization of the telecommunications carriers face competitive environment, network integration leads to the importance of business, after all; and further information on China Mobile CM-IMS technology overview and positioning; general introduction of this article sources and paper structure issues. Chapter Ⅱ Review of relevant, comprehensive definitions and features described IMS, ISO and progress; introduced the IMS-related protocols and architecture.Chapter Ⅲ, CM-IMS implementation of fixed-line access to China Mobile CM-IMS system interoperability and routing options and fixed-line access program of study and research in the fixed-line real-time fax solution integration process.Chapter Ⅳ, China Tietong IMS fixed access solutions, the first of the China Tietong’s network status, the overall construction plan design; and then separately from the core network and business solutions, transport and metro access network-building programs, network management and business support building programs and other aspects of the system in detail CHINA TIETONG access mobile CM-IMS solutions.Chapter Ⅴ, Conclusion, summarizes the focus of this article discussed, and proposed IMS fixed-line access for further study. Because at this stage China Tietong and China Mobile convergence has not yet put into full-service network, so this study focus mainly on the program design, implementation issues for the program is temporarily unable to carry out the actual argument.Research paper on China Mobile and China Tietong’s full-service joint development of important reference value; the same time, the study of other carriers also have a very important reference.
