面向LTE基站回传的PTN核心层L3网络组网思路探讨

Discussion of LTE Backhaul Service-Oriented PTN L3 Core Network Design

描述了在TD-LTE网络的场景中PTN核心层L3网络的组网架构和组网思路。首先介绍了TD-LTE无线网的承载要求;其次,分析了目前主流的PTN 3层功能和PTN+CE的承载网络架构及PTN L3网络的组网思路;最后,分析了城域网PTN L3网络的相应演进方式,为今后网络的发展提供了一定的借鉴。

The TD-LTE network scenario PTN core layer L3 networking architectures and networking ideas were described. Firstly, the TD-LTE radio network requirements were introduced and the existing metro transport network appropriate framework was described. Secondly, the current PTN L3 functions, PTN＋CE bearer network architecture, PTN L3 network detailed deployment and designing were analyzed. Finally, PTN metro L3 network evolution was analyzed, a reference to the future development of the network was provided.
