一种基于MDT的基站工参诊断及实现方法

A method for base station parameter diagnosis and implementation based on MDT

作为一种移动蜂窝网络的优化手段,MDT的基本原理是基于商用终端的测量报告来实现对移动通信网络的优化,因其易实施、易推广、代价低等优势,MDT方法备受网络优化人员的青睐。文章在MDT方法的基础上,提出了一种基于MDT的基站工参诊断方法,该方法基于基站虚拟经纬度和方位角的计算,结合栅格聚类法,通过与运营商平台基站数据库数值对比,进而可有效实现对异常工参的诊断。目前,该方法已在现网中广泛应用。

As an optimization method of mobile cellular network,the basic principle of MDT is to realize the optimization of mobile communication network based on the measurement report of commercial terminals.Because of its advantages of easy implementation,easy promotion and low cost,MDT method is favored by network optimization personnel.Based on the MDT method,this paper proposes a method of base station parameter diagnosis based on MDT.The method is based on the calculation of virtual longitude,latitude and azimuth of base station,combined with raster clustering method,and by comparing with the base station database of operator platform,the abnormal parameter diagnosis can be effectively realized.At present,this method has been widely used in live networks.
