摘　　要：当前网络优化工作越来越从KPI指标优化向用户感知优化转变,但是在日常的优化工作中,如何将用户感知与常规的无线环境优化相关联,并通过优化无线环境实现用户感知的提升,仍然是困扰优化人员的难题。对海量实测数据进行覆盖、干扰与数据速率的关联分析,特别关注覆盖、干扰与影响用户体验的下限速率的关系,得到无线环境与数据速率这一重要的内在关联关系,从而确定保证不同业务速率要求的无线环境需求,为网络规划和优化工作提供参考。As the key point of network optimization developing to improve user experience from increasing the KQI indexes, how to improve user experience by radio environment optimization has been a difficulty for network optimization staffs. By researching on the relevance between radio environment and data throughput, especially the relations between coverage/interference and low bit rate which has influence on user experience based on massive data, the RSCP and Ec/Io thresholds was obtained to ensure good user experience of different bit rate requirements, which can provide reference for wireless network construction and optimization.
