摘要网络优化工作是一项技术含量较高的日常维护工作，要求不断监视网络的各项技术数 据、路测，根据发现的问题，通过对设备、参数的调整，使网络的性能指标达到最佳状态， 最大限度地发挥网络能力，提高网络的平均服务质量。论文根据 H 市 CDMA 无线网络的容量和覆盖需求以及其它特殊需求，参照覆盖区域 的实际特征，设计出合理并且可行的无线网络布局，以最小的投资满足系统需求，同时根 据 H 地区 CDMA 无线系统现有网络的状况，基于对测试数据或性能数据的分析，发现网 络存在的问题并提出相应的解决方案，正确实施后再加以验证，确认问题己得到解决，为 现有的系统配置下提供最优的网络服务质量。论文研究现有的系统资源，例如系统的基础设施和频谱，通过优化使得系统能够达到 最佳的性能。为了测量通信网络的性能，选择依赖于不同的网络的性能评价体系，设定一 些衡量的指标来评估网络。无线网络性能往往体现在语音质量下降、无线覆盖面减低、呼 叫失败、还包括帧误差率、软区切换比率等方面，通过检查故障，发现系统容量和建筑物 穿透率等都影响到 CDMA 网络的性能。通过优化，调整系统性能达到最优值时的指标参 数，以提高网络质量。IAbstractNetwork optimization work is a high technical content of the daily maintenance work, require constant monitoring network in all kinds of technical data, the road test, according to the problems found, according to the adjustment of parameters of the equipment, make the performance of the network to achieve the best condition, maximize the network capacity, improve the quality of the average service network.Paper according to the capacity of CDMA wireless network in H and coverage requirements and other special demand, with reference to the actual characteristics of coverage, design a reasonable and feasible wireless network layout, meet the demand of the system with minimal investment, at the same time, according to the status of the existing network H in CDMA wireless system, based on the analysis of test data and performance data, find the problems existing in the network and proposes the corresponding solution, right after the implementation of verified again, confirm the problem has solved, provide optimal under the existing system configuration of network quality of service.The paper studies the existing system resources, such as system infrastructure and spectrum, by optimizing the enables the system to achieve the best performance. In order to measure the performance of the communication network, the choice depends on the different network performance evaluation system, set some measure to evaluate the network. Wireless network performance is often reflected
