WCDMA网络用户感知与无线环境关联分析研究

摘要

As the key point of network optimization developing to improve user experience from increasing the KQI indexes, how to im-prove 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, especial y 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 en-sure good user experience of different bit rate requirements, which can provide reference for wireless network construction and optimization.%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。
