摘　　要：在国家政策的大力推动下,我国5G网络逐步完善,但受5G应用发展、终端普及率、用户习惯等因素影响,业务未能快速迁移至5G。在较长一段时期内,4G网络仍将作为业务承载的重要网络与5G网络共存。4G网络经过多年来的扩建,频段分散、设备较多,网络架构复杂,给网络的运营维护以及后续演进带来了一定的压力。如何利用5G网络建设创造的有利条件,开展无线网络的极简化改造是当前的一个重要课题。无线网络极简化改造主要包括无线网络分层极简和无线站点极简2个方面:网络分层极简是对现有网络进行梳理,确定基础覆盖层频段,并通过网络优化调整等方式对其进行完善,为网络的逐步简化创造条件;站点极简是从天面整合、室内基带处理单元(Building Baseband Unit,BBU)集中式无线接入网(Centralized-Radio Access Network,C-RAN)方式部署、设备整合3个方面开展极简改造,实现资源的整合与挖潜,降低运营成本,提升资源使用效能。With the vigorous promotion of national policies,my country’s 5G network is gradually improving.However,due to factors such as 5G application development,terminal penetration rate,and user habits,services have not been quickly migrated to 5G.For a long period of time,4G networks will continue to coexist with 5G networks as an important network for carrying services.After years of expansion,the 4G network has scattered frequency bands,many devices,and a complex network architecture,which has brought certain pressure to network operation and maintenance and subsequent evolution.How to take advantage of the favorable conditions created by 5G network construction to carry out the minimalist transformation of the wireless network is an important issue at present.This research explores two aspects of wireless network layering simplicity and wireless site simplicity.The network layering simplicity is mainly to sort out the existing network,determine the frequency band of the basic coverage layer,and improve it through network optimization and adjustment.Create conditions for the gradual simplification of the network.Site simplification is to carry out simplification transformation from the three aspects of antenna integration,Building Baseband Unit(BBU)Centralized-Radio Access Network(C-RAN)concentration,and equipment integration to realize resource integration and potential tapping,reduce operating costs,and improve resource use efficiency.
