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.
