摘　　要：在移动通信网络中,小区覆盖范围出现偏差将影响小区的各项性能指标,分析小区覆盖范围对于网络优化至关重要。文章提出了一种小区覆盖范围的分析方法:基于大量手机实测数据,分析小区电平、载干比采样点数目以及小区间距离等多种因素,得出小区覆盖范围示意图。图中可发现覆盖出现偏差的问题小区,相比传统路测方法,具有成本低、实时性强、显示直观等优点。In the mobile network, a deviation of cell coverage area will influence many performance indicator.Therefore, cell coverage area analysis is vital to network optimization. This method, which is based on phone measured data, can help to achieve effective and real-time analysis of cell coverage area, then get the chart of cell coverage area. Through this chart, we can discover the ceils where deviations occur by analyzing downlink level and sample points of CIR. In contrast to the traditional way of road test, this method is more economic, real-time support and the way showing results is more intuitive.
