摘　　要：5G网络的商用部署进程是一个基于4G网络进行的长期演进的替换、升级、迭代的过程。在5G网络部署的前、中期阶段,5G网络信号覆盖尚不完善,为保障用户业务的连续性体验,4G网络无疑是最好的补充。因此4G/5G融合组网,以及互操作技术将是各大运营商在网络演进发展中需要重点考虑的问题之一。随着5GSA网络商用发展,SA开户用户数逐步上升,5GSA用户通过4G网络(占比较大)接入后通过现网4GSGW接到5GSMF/UPF会造成承载网带宽负荷逐渐变高,如何能降低负荷、提升用户体验成为公司运营的关键。文章从5G网络概述、4/5G网络融合必要性分析、4/5G融合改造介绍及效果等几方面做了详细分析。Commercial deployment of 5G networks is a process of replacement,upgrade,and iteration based on long-term evolution of 4G networks.In the early and middle stages of 5G network deployment,the signal coverage of 5G networks is not perfect.To ensure service continuity,4G networks are the best supplement.Therefore,4G/5G converged networking and interoperability technologies will be one of the key issues that major carriers need to consider during network evolution and development.With the commercial development of 5G SA networks,the number of defined SA subscribers gradually increases.After5G SA subscribers access the 4G network(a large proportion)and connect to the 5G SMF/UPF through the 4G S-GW on the live network,the bandwidth load of the bearer network gradually increases.How to reduce the load and improve user experience becomes the key to company operations.This document describes the 5G network overview,necessity analysis of 45G network convergence,introduction and effect of 45G convergence reconstruction.
