NSA组网下2G/3G/4G/5G系统协同策略的研究

Research on Collaboration Strategy of 2G/3G/4G/5G System under NSA Network

从NSA组网原理出发,以中国移动的现网实际情况和需求为例,通过分析不同系统的特点,探讨了NSA模式下2G/3G/4G/5G组网下不同网络间的协同策略。经测试验证,该套策略对5G网络的覆盖、质量以及用户的下载速率等指标均有较好的改善,能够满足现网实际网络的组网要求,同时也可为后续5G大规模基站建设和入网提供行之有效的参考方案。

Based on the NSA networking principle,this paper takes the actual situation and requirements of China Mobile's current network as an example,and analyzes the characteristics of different systems to discuss the inter-network collaboration strategies under the 2G/3G/4G/5G networking in the NSA mode.Through testing and verification,the strategies improve the coverage,quality and download rate of 5G networks,and can meet the actual networking requirements of the current network.At the same time,an effective reference solution is provided to the subsequent construction of large-scale 5G base stations and network access.
