摘要

2019年6月，工业和信息化部发布 5G商用牌照，加快了运营商5G网络部署进程。NSA组网是5G网络部署初期的较好选择，SA组网是5G网络的目标架构，如何在当前网络基础上向5G平滑演进是需要考虑的问题。简要介绍了4G网络结构，优化了回传承载网络以满足5G发展初期带宽需求，采用NFV技术，基于 CUPS 架构对 EPC 进行了重构以更好地支持网络演进。最后介绍了 4G/5G 互操作网络架构，分析了向SA组网演进的部署方案，对5G核心网建设提供参考。

Abstract

In June 2019

the Ministry of Industry and Information Technology officially issued a 5G commercial license

which accelerated the deployment of telecom operator’s network of 5G.NSA networking is a good choice to deploy 5G networks in the early stage

and SA networking is the target architecture of 5G networks.Based on the network existing

how to smooth evolution to 5G is a problem to be considered.The architecture of 4G networks was introduced briefly

the return bearer network was optimized to meet the bandwidth requirement in the early stage of 5G development

Through NFV technology the EPC was reconstructed based on CUPS architecture to support network evolution better.Finally

the inter working architecture of 4G/5G was introduced

the deployment and evolution scheme for SA network was analyzed

which provides reference for the construction of 5G core network.
