Studying For The Realizing Manner Of Intelligence And Reconstruction Solution For The Fixed Network

The services of fixed network was impacted by the rapid development of mobile communication and Internet. In order to be sustainable development and comply with the change of communication demands, China Telecom Groups is implementing the revolution strategy changing from traditional telecommunication carriers to integrative information service provider. The intelligence of fixed network is one important contents of the network and technical reforming in strategic reforming, and an important technical action of excavation the existing telephone network potential. In order to implement the fixed telephone network transformation. this paper put emphasis on researching the intelligence reformation of fixed network, choosing the appropriate intelligence reformation plan for success.The core of fix network intelligence reformation is to bring new units-- Subscriber Data Center (SDC) and Service Control Platform (SCP) into fix network. The switch and SDC carry on the interactive information through the related protocols, realize to see about the user data and provide the various increment services for users. The main communication protocols of soft switch: MAP (Mobile Application part) and MAP+ (Predigestion of Mobile Application part) are discussed, three kinds of basic projects of network's constitution for fix network's reformation are studied, the advantage and disadvantage of the three kinds of basic projects are analyzed in this thesis from four aspects: the difficulty of network reformation, the influence of multi-network oasis in future, the network's construction expense, the network's operation and maintenance expense.Base on the actuality and characteristics of the switch network of Chongqing Telecom, thinking about the difficulty of network reformation, considering the oasis of network such as fix network, PHS network, the third generation mobile network in future, the project of network's constitution for fix network's reformation which most adapt to Chongqing Telecom is established. The project is designed detailedly, and the several important questions of the project in network's constitutes for fix network's reformation are more studied: the choice of communication protocol between soft switch system and SHLR, the coding rule of physical number, the method to insure the consistency of customer data in the process of network reformation.The operation project is one important part of fix network's reformation. The project is partitioned several parts, such as the preparation of cutover, the input of operation data of user, the cutover of voice services and the cutover of services. Then the processes of cutover are designed. In order to guarantee the present business on network not be influenced in the process of network reformation, the reformation of network is achieved, and the calm transition of traditional switch network to intelligent network is realized. The best fixed network intelligence reformation solution for Chongqing Telecom is proposed in this thesis.
