[Abstract] In this paper, a virtual core network architecture based on virtual network and software-defined network (SDN) is proposed. This architecture simplifies the interface and protocol of core network and integrates service chain management. This architecture also has an intelligent management module that supports future mobile network automation deployment, automatic configuration, self optimization, self-healing and other functions. In this way, it can better support the complex and changeable scenarios of 5G. In addition, this architecture integrates the functions of core network and separates the processing module and the user context in order to better support core network distributed processing.
