摘　　要：SA组网的5G核心网已开始大规模部署,智能城域网是中国联通5G网络的承载解决方案,但其建设尚处于起步阶段,需充分考虑5G核心网的业务承载需求。简要介绍了当前承载网络结构,并结合中国联通现网,对5G核心网信令面、用户面以及4G/5G互操作等业务承载提出了解决方案,对5G建设及后续的网络融合提供了参考。5G core network based on SA network has begun to be deployed on a large scale,intelligent metro network is the bearing solution of China Unicom's 5G network,while the construction of intelligent metro network is still in the early stage,the service bearing requirements of 5G core network should be fully considered.It briefly introduces the current bearer network structure,and based on the current network structure of China Unicom,it proposes solutions for the 5G core network signaling plane,user plane and 4G/5G interoperation,which provides reference for 5G construction and subsequent network convergence.
