基于IP的移动核心网组网策略研究

With the development of mobile communication technology, the transformation of mobile core network based on IP has become the choice of major mainstream operators at home and abroad. Network IP has become the general trend. IMS converged communication technology is also recognized as the integration basis of circuit network and packet network. This paper analyzes and discusses the networking strategy and application of IP based mobile core network. Starting with the network architecture, this paper analyzes the core network, key network elements of the core network, relevant gateways and network protocols. Based on the structure of IMS system, the networking strategy of core network is designed. According to the networking strategy, the application design of volte voice deployment in Liaoning Province is carried out, so that it can make voice calls on LTE network.
