摘 要:在移动通信网络中天线方位角和小区覆盖发生偏差是影响移动通信质量的关键因素,传统采用人工测量或路测方式核查,耗时耗力。本文提出了一种新的智能性天线方位角计算及小区覆盖分析方法,该方法基于OMC中大量手机实测数据,计算天线方位角及偏差,从电平分布、采样点分布、干扰分类等多种因素来分析小区覆盖问题,同时基于GIS平台进行地图定位及呈现。该方法相比传统测量方法具有智能性、成本低、精度高的特点,已在实际系统中得到证实。In mobile network, antenna azimuth angle and cell coverage occurring deviation are the critical factors on the quality of mobile communication.The traditional check methods are measured by manpower which costs much time and resource.This paper presents an innovative method on azimuth angle automatic calculation and cell coverage analysis.The methods include 3 parts.The innovative calculation algorithm on deviation of antenna azimuth angle is based on real mobile station data collected in OMC system.The cell coverage analysis algorithm considers multiple factors (signal level distribution, sampling points distribution, category of interferences) to solve the difficulty on recognition of cell coverage differences.The calculation and analysis results are presented in map based on GIS platform.Compared with traditional methods, this new method has several advantages:intelligence, low cost, high precision.Further more, this paper presents the system design based on this method.The designed system has been deployed in real mobile network and gain good effects
