摘要

中国电信cdma2000 Ev-Do 网络在用户密集区采用了多载波方案，多载波技术在解决容量的同时，也因不同载波有效覆盖范围差异而影响局部区域用户的上网感知。传统性能指标分析、DT等多载波优化方法耗时耗力。根据多载波无线环境典型模型并结合DRC及起呼数据分析，提出了一种分析控制叠加载波与基本载波覆盖一致性的有效方法，使网络优化由经验手段转变为量化策略，提高了现有3G网络的优化效率。

Abstract

In the crowded area，China Telecom cdma2000 Ev-Do sector is configured with multi-carrier for improving the capacity.Nevertheless，the users’ experience is influenced because of the carrier’s effective coverage difference.Meanwhile，the traditional optimization methods for multi-carrier coverage such as performance index analysis and drive test are time-consuming and costly.According to the multi-carrier wireless environment typical model and combining with the DRC and call data analysis，an effective method to control the coverage of each carrier was proposed.This method can improve the optimization efficiency of China Telecom cdma2000 network by transforming the empirical method into quantitative strategy.
