摘 要：随着中国加入 WTO 后运营商之间竞争的加剧，网络的质量已经成了决定移动通信运营商命运的根本要素。网络优化正成为移动通信运营商未来的工作重点。现在，运营商们关心的是，如何在现有网络基础上，通过优化与完善，从而最大限度地挖掘网络潜力。

网络优化的目标是提高或保持网络质量，而网络质量是各种因素相互作用的结果，随着优化工作的深入开展和优化技术的提高，优化已经从当前的网络渗透到包括市场预测、网络规划、工程实施直至投入运营的整个循环过程的每个环节。

本论文在深入研究 GSM 系统原理的基础上，结合成都联通 GSM 无线网络，对成都联通 GSM 网络目前反映突出的网络问题进行分析与排查，提出并实施了切合工程实际的无线网络优化方案，大幅度提升网络质量，并以此为基础进一步研究了用户话务行为，用户增长趋势，对下一期工程建设和网络扩容提出了指导性建议，完成了下一期网络规划设计的初步方案，预设方案已应用在新的工程设计建设中。

After China entered the WTO, competition between service providers has intensified. Network quality has become a critical element for service providers.Network optimization will become an very important task in the future.Currently, service providers are keen to find out how network optimization can maximize the current network performance.

The goal of network optimization is to improve and maintain network quality. Network quality is affected by various factors. Current network optimization includes coverage, traffic forecast, network planning, network implementation and engineering services.

This article discusses and analyzes ChengDu GSM network current issues. It presents proposals that have been implemented, resulting in network quality improvements. It also analyzed the subscriber calling pattern and subscriber growth pattern. Based on these data, the article provides suggestions and network planning for the next phase of engineering and network expansion. Some of these suggestions are in progress.

Keywords： GSM mobile network, network, optimization
