面向5G承载的城域PTN向SPN演进分析

Analysis of the evolution of metropolitan area PTN to SPN network for 5G bearer

目前我国5G商用网络部署已近在咫尺,根据5G实验网对SPN技术的验证情况,中国移动已经明确采用PTN演进SPN网络作为5G承载网,本文立足现阶段PTN网络现状,从5G发展各阶段的需求特征出发,讨论分析PTN向SPN网络演进发展步骤,分阶段建设思路.

At present,China’s 5G commercial network deployment is close at hand.According to the verification of SPN technology by 5G experimental network,China Mobile has explicitly adopted PTN evolution SPN network as 5G bearer network.This paper is based on the current status of PTN network,from the 5G development stage.Starting from the characteristics of business requirements,discuss and analyze the evolution steps of PTN to SPN network,and build ideas in stages.
