Optimization and Design of Networking Based on IMS

With the development of Internet technology, the demand of interconnection between fixed and mobile networks and different heterogeneous networks is further enhanced. IP Multimedia Subsystem (IMS) is an important way to solve the convergence of mobile and fixed networks, and introduce the triple convergence of voice, data and video services. This paper summarizes and analyzes the development and research status of IMS networking, and then analyzes the basic theory and network architecture of IMS in detail. Finally, based on the practical application background requirements, from the intra-domain networking and cross-domain networking, the disaster recovery and backup optimization scheme is proposed. Combined with the specific IMS network construction scene, the IMS single communication station and multiple communication station network construction are designed and introduced in detail, which gives a typical practical application background presentation and sufficient theoretical guidance for IMS networking.
