摘要
为了分析移动通信在未来几年从4G向5G演进过程中对传输尤其是UTN网络的影响,基于无线网特性的变化以及容量、连接、时延敏感度等特性的大幅提升,分析了5G发展对传输网络的需求,基于5G需求提出了5G目标承载网架构、前传和后传的承载方案,并且对城域传输网内带宽进行了测算,探讨了面向5G的城域UTN网络的核心层、汇聚层、接入层的演进方向和技术特征。
In order to analyze the influence of mobile communication which evolves from 4G to 5G,on transmission,especially on UTN,based on the change of wireless network characteristic and the great increase of capacity,connection and time delay sensitivity,it analyzes the demand of 5G development on transmission network,presents 5G goal carrying network architecture,preand post-transport bearers.It also calculates metro area transmission network bandwidth,discusses the evolution and technical features of core layer,convergence layer and access layer of 5G-oriented metro area UTN.
