摘　　要：5G网络已启动建设,研究如何简化2G/3G/4G网络、将其频率资源用于5G网络发展是重要课题。对标中国联通及竞争对手现有的频率资源,分析了用户、终端、语音及数据业务承载现状。基于4G初期终端渗透情况进行了4G、5G流量预测,结合4G开网后3G/4G流量历史发展情况,研判4G业务拐点将在2021年上半年出现且4G流量将长期维持在一定水平。综合考虑5G设备、终端发展路标,建议2021年优先重耕2.1 GHz补充5G深度及上行覆盖,保留1.8 GHz长期作为4G主力承载频段。The construction of 5G network has begun.How to simplify 2G/3G/4G networks and use their frequency resources for 5G network development has become an important topic.In view of the existing frequency resources of China Unicom and its competitors,it analyzes the current status of users,terminals and service bearers.It predicts 4G/5G traffic based on the initial 4G terminal penetration rate.Combined with the historical development of 3G/4G traffic after 4G network opening,it predicts that the inflection point of 4G flow will appear in the first half of 2021 and 4G traffic will remain at a certain level for a long time.At the same time,considering 5G equipment and terminal development roadmaps,it is recommended to prioritize 2.1 GHz in 2021 to supplement 5G depth and uplink coverage,and reserve 1.8 GHz as the main carrier frequency band for 4G for a long time.
