摘　　要：网络功能虚拟化将传统网络设备的软件功能和硬件功能解耦合,从而降低网络的投资和运营成本,提高新业务的部署效率。SDN为网络功能虚拟化的承载网提供了解决方案,确保网络功能虚拟化的实现。主要对IMS核心网网络功能虚拟化方案进行了论述,并基于SDN架构提出了IMS核心网虚拟化环境下的承载网组网方案。As network function virtualization （NFV） decouple the software functions and hardware functions of traditional network equipments, it decreases the investment and operating costs to enhance the deployment efficiency of new business. SDN provides a solution to NFV bearer network and ensures the implementation of NFV. In this paper, the solution to NFV of IMS core network is discussed, as well as the networking scheme of the bearer network in the environment of IMS core network visualization based on SDN framework is proposed.
