摘　　要：针对移动分组域核心网的发展,研究了CDMA和EPC的网络结构,分析了EPC网络向SDN结构发展的趋势。通过对比EPC的网络组成和SDN网络架构的相似性,确定了基于SDN架构的EPC是移动分组域核心网发展的重要目标,是网络发展中的一个重要里程碑,关联体和融合体是EPC和SDN两者共同发展的组成形式。SDN网络促进了EPC的进一步发展,完善整个架构网元之间的接口是下一步的重要研究工作。Considering the development of mobile packet core network, the network structures of CDMA and EPC are analyzed and the development tendency of evolution from EPN network to SDN is also illustrated. By comparing the similarity of EPC network and SDN architecture, it is identified that the EPC based on SDN architecture is the important objective of packet core network development as well as the milestone in network evolution. Correlation body and fusion body are the combination of EPC and SDN development. SDN network promotes the further development of EPC; in the meantime, to improve the interface between network elements is the important task in the future.
