由NSA切换SA混合组网下的5G优化

Handover Technology of 5G NSA and SA Hybrid Networking

在近几年5G商用的背景下,先分别对非独立组网(No-Standalone,NSA)、独立组网(Standalone,SA)的各自组网架构方案,以及NSA/SA混合组网方案进行分析;然后研究了NSA/SA混合组网共存场景下,NSA至SA、SA至NSA两大组网连接态切换技术;最后结合项目实例分别测试了NSA/SA混合组网的上传、下行、时延各方面性能,测试结果发现NSA/SA混合组网可以较好地实现终端自适应网络。基于此技术,5G用户在不同部署区域内移动的过程中,数据业务可以平缓切换,可以为全部终端带来良好的5G商用感受。

In the context of 5G commercial use in recent years,first,the networking architecture schemes of NSA(No-Standalone) and SA(Standalone),and the NSA/SA hybrid networking scheme are analyzed respectively.Then,in the network coexistence scenario of NSA/SA hybrid networking,two networking connection state switching from NSA to SA and SA to NSA are studied.Finally,the performance of upload,downlink and delay of NSA/SA hybrid networking is tested combined with project examples.The test results indicate that the NSA/SA hybrid network can better realize the terminal adaptive network.Based on this technology,data services can be smoothly switched in the process of 5G users moving in different deployment areas,so it can bring a good 5G commercial experience to all terminals.
