5G承载网关键技术与建设方案

The Key Technology of 5G Transmission Network and Construction

第五代移动通信(5G)技术是新一代无线通信系统,能够承载大带宽、低时延和高可靠性的各类通信业务。在5G通信的各项网络建设中,承载网将面临巨大的挑战,一方面单站宽带相比于4G提升了近100倍,二是5G无线网络的切片功能将对现有的分组传送网带来巨大的挑战。文章回顾了4G网络的传送网建设情况,分析了5G通信带来的带宽、时延、网络切片等承载需求,提出了SPN技术为基础的传送网技术架构,提供了5G承载网的解决方案,并对网络的阶段性建设和演进做出了分析。

The fifth generation mobile communication is the new generation wireless communication system,it can transfers large bandwidth、low latency and high reliability communication business.In the construction of the 5 th generation network,it have a great challenges in the transmission network,the broadband of 5 G station is 100 times compared with 4 G station,the function section of 5 G mobile network is a huge challenges too.The article reviews the transmission network of 4 G network,analysis the transmission demand of the 5 G network,proposes the technical framework of transmission network based on SPN technology,and also provides the Solution of the 5 G transmission network,analysis the stage construction of the network.
