摘要

移动互联网络中，速率是业务感知的重要组成部分，研究网络速率的提升方法是数据业务优化的重要课题。首先从CQI与Ec/Io、CQI与速率的关系分析，阐述了基于CQI优化HSDPA速率的理论依据，提出了以降低CQI差比例、解决CQI坏小区为目标提升HSDPA速率的优化思路，结合CQI坏小区处理，重点介绍了优化无线环境、功率配比、HSDPA移动性管理参数、多载波策略参数、资源调度算法改善CQI的典型方案，通过效果评估，方案的实施对速率提升有一定效果，验证了基于CQI的优化思路具有针对性、可行性和推广价值。%In the mobile Internet, the rate is an important part of user perception, how to improve network data rate is an important issue for data optimization. Firstly, it analyzes the relationship between the CQI and EC/IO, CQI and rate, elaborates CQI-based opti-mizing HSDPA rate theory, proposes HSDPA rate improvement ideas which aim to reduce the proportion of poor CQI, and solve CQI bad cel . Combined CQI bad cel treatment, it focuses on optimizing the wireless environment, the power ratio, HSD-PA mobility management parameters, multi-carrier strategy parameters, resource scheduling algorithm to improve the CQI un-der typical scenario. Through performance evaluation, it verifies that CQI-based HSDPA rate optimization ideas have pertinen-cy, feasibility and promotional value.
