接通率是衡量GSM网络运行质量重要的指标之一，本文根据 GSM网络优化的基本理论，针对GSM网络中低接通率现象，对影响GSM网络优化中接通率的因素进行了细致的分析与研究，提出了一套有效可行的优化方法，逐个排除故障原因，从而达到了提高接通率、优化GSM网络的目的，并针对提高GSM网络接通率设计开发了GSM网络优化软件。最后,对实例安阳市区GSM网络中存在的低接通率等问题进行了分析及其优化，并证实了优化软件中提高接通率方法的可行性、实效性。

Callcompletion rate is an important measure of the quality of the GSM networks.According to the basic theory of GSM network optimization,the paper analyse and studies the phenomenon of the low callcompletion rates,details the factors which affect the rates of GSM network optimization and proposes a set of feasible and effective optimization methods,and thus achieves an improved callcompletion rate,and an optimized  GSM network,and designs the software of  GSM network optimization. Finally,an instance of the GSM network in An Yang where exists low callcompletion rates is discussed,and the optimization software to improve the callcompletion rates is confirmed.
