摘　　要：5G网络架构的变化对承载网提出了新的挑战。通过研究和跟进RAN侧重构及网络云化等内容,探讨5G网络承载需求,分析网络不确定性对承载网建设的影响,并结合近年来基础网络架构的搭建,给出RAN侧部署方式建议及基础网络资源储备工作要求。最后提出5G X-haul网络的演进方案及承载部署建议,为5G网络的快速部署奠定基础。Changes in 5G network architecture bring new challenges to bearer network. It researches and tracks the RAN reconstructionand network cloudization,etc,then analyzes the uncertainty of 5G network and the impact on the construction of bearer network.Combined with the construction of the local basic network architecture in recent years,the RAN deployment methodand the basic network resource reserve work requirements are given. Finally some suggestions for the 5G X-haul networkevolution and bearer network deployment are proposed which bulid the foundation for rapid deployment of 5G network.
