[Abstract]:In order to support IP multimedia service, the third generation mobile communication partner organization (3GPP) put forward the IP multimedia subsystem in Release5. This system has changed people's cognition of traditional network. The IMS network system based on session initialization protocol (SIP). It has the characteristics of network control and service separation, service and load separation, flexible service development, access independence and so on. Through the IMS network based on SIP, users can not be restricted by the use of terminal and network. At present, the competition in the telecommunication market is becoming increasingly fierce, the customer demand is constantly changing, the focus of the telecom operators is from increasing the scale of users to improving the network capability. In order to adapt to the development of communication network, enhance the market competitiveness of enterprises and reduce the running cost of the network, Research on Mobile and fixed Network Fusion of Telecom operators IMS is the key technology. IMS is a flat network structure strong network capability rich communication services flexible network access. To meet the needs of telecom operators in the future communication network deployment. In recent years, the major telecom operators at home and abroad have taken the IMS network as a means to optimize network resources and enhance the network service capability. Telecom operators initially conducted IMS network internal field testing, to IMS networks, services, terminals, Through the test research in support and other aspects, the IMS network capability was verified, and the IMS network standard specification of its own enterprise was established. Later, through the external field test experiment of IMS network, Considering the development of future communication networks, it is of great significance for telecom operators to study the evolution of existing networks to IMS networks. This paper first introduces the research background, significance and purpose of the project, and the current research situation at home and abroad, and then introduces the related technologies of IMS, including the introduction of IMS network structure and the role of SIP protocol in IMS. This paper studies the interworking of IMS network elements. Combined with the present situation and existing problems of Liaoning Unicom's fixed network, the paper studies the construction of IMS network based on fixed network transformation, and designs the construction scheme of IMS network with existing fixed network interworking. It mainly includes IMS basic network architecture, service model, main network element setting, network scale prediction, disaster recovery mode of core network element, and so on. This paper studies the setup scheme of IMS network application server and realizes the inheritance of all fixed network services. This paper studies the direct voice interworking between IMS network and fixed network. The interworking between IMS network and other circuit-domain networks is realized through the transfer of fixed network converters. According to the principle of network interworking, the routing plan of voice interworking between IMS network and existing network is analyzed, and the test of IMS voice call is carried out. The routing plan of voice interworking is confirmed, the voice interworking with existing network is realized, and the IMS network construction scheme of this study is proved to be feasible. Taking into account the requirements of network transformation and service development of telecom operators at present, the paper realizes the goal of telecom network development, and provides a reference for the construction and implementation of IMS network of telecom operators.
