摘要
5G业务快速发展,如何搭建快速、灵活的5G承载网成为5G业务开展中亟待解决的问题。通过对同步传输网络(Synchronous Transmission Network,STN)建网进行摸索,分析了不同阶段、不同层级的STN回传网络架构的演进模型,并建立了5G基站的测算模型,在此基础上,对不同阶段的共享组网方式进行分析,提供共建共享的组网模式以及网络低时延的解决办法,并结合灵活以太网(Flexible Ethernet,FlexE)技术,提高STN承载网络的灵活性,并对STN承载网络的前传方案进行对比分析与造价分析,以期为方案的选择提供参考。
In the rapid development of 5G services today,how to build a fast and flexible 5G bearer network has become an urgent problem to be solved in the development of 5G services,through the exploration of Synchronous Transmission Network(STN)construction,the evolution model of STN backhaul network architecture at different stages and different levels is analyzed,and the calculation model of 5G base station is established,on this basis,the shared networking mode at different stages is analyzed,and the solution of co-construction and sharing networking mode and low network latency is provided,and combined with Flexible Ethernet(FlexE)technology.Improve the flexibility of STN bearer network,and conduct comparative analysis and cost analysis of fronthaul scheme of STN bearer network,in order to provide a certain reference for the selection of scheme.
