摘　　要：独立组网是5G网络的目标架构,基于大区中心的集约化方式是建设云化的5G核心网的较好选择,具有部署快速、运维高效等优点,如何部署则是当前需要考虑的问题。首先介绍了大区数据中心的云网协同网络架构以及物理资源池的规划方法,实现数据中心的高可靠性设计。其次介绍了4G/5G互操作架构,分析了5G核心网的平滑演进方案。最后对大区化部署核心网的信令风暴问题给出了预防和处理建议。SA networking is the target architecture of 5 G network,and the intensive mode based on the regional center is a better choice for building the cloud 5 G core network,which has the advantages of more rapid deployment,efficient operation and maintenance,etc.How to deploy is a problem which should be considered currently.Firstly,the cloud network synergy architecture of data center and the design method of physical resource pool are introduced,which realizes the high reliability design of data center.Secondly,the interworking architecture of 4 G/5 G is introduced,and the scheme of smooth evolution to 5 G core network is analyzed.Finally,the recommendations are given to prevent and deal with the signaling storm of core network deployed based on regionalization.
