基于5GC网络架构的VPDN组网方案研究

Research on VPDN Networking Scheme Based on 5GC Network Architecture

随着5G SA网络的大规模部署以及企业网终端逐步升级迭代支持5G网络,政企行业客户提出利用5G网络来实现VPDN业务接入的迫切需求。结合某省联通4G VPDN业务组网部署现状,从网络重构、保障业务容灾、提升业务感知、方便业务继承等多个角度综合考虑,对如何快速实现5G VPDN网络功能进行深入分析,积极探索基于5GC云化架构的4G VPDN业务向5G VPDN平滑过渡的组网模式,给出5G SA网络下5G VPDN组网方案。

With the large-scale deployment of 5G SA networks and the gradual upgrade and iteration of enterprise network terminals to support 5G networks,customers in the government and enterprise industries have put forward an urgent need to use 5G networks to realize VPDN service access.Combining with the current deployment status of 4G VPDN business networking of a province branch of China Unicom,it comprehensively considers from multiple perspectives such as network reconfiguration,ensuring business disaster tolerance,improving business perception and facilitating business inheritance,conducts an indepth analysis of how to implement 5G VPDN network functions quickly,actively explores the networking mode of smooth transition from 4G VPDN business to 5G VPDN based on the 5GC cloud architecture,and gives a 5G VPDN networking scheme for the 5G SA network.
