摘　　要：移动通信网络传统的干扰优化主要针对系统内、系统间、外部短距干扰,TD-LTE系统内GPS干扰具有干扰强度高,隐蔽性强的特点,如果不结合指标统计与实地测试,可能会被认为其它类型的干扰。本文阐述了TD-LTE系统可能出现的干扰类型,在此基础上指出GPS干扰的特征以及对用户的影响,同时,从实例中阐述GPS干扰判决过程中的指标监测及排查分析,还有局部基站GPS失步后的监测方式及优化分析。The interference of mobile communication network optimization system is mainly for the intra system,inter system and short external interference.GPS interference in TD-LTE system has the characteristics of high interference intensity and concealment.If not combined with indicator statistics with field tests,other types of interference may be considered.This paper describes the types of interference that may occur in TD-LTE systems.On this basis,the characteristics of GPS interference and its impact on users are pointed out.At the same time,from the example of GPS interference in the process of monitoring the indicators and monitoring and analysis,as well as local base station GPS after the failure of monitoring methods and optimization analysis.
