摘　　要：针对近期LTE伪基站日益增多的情况,分析了伪基站干扰对网络覆盖、业务质量的影响,提出了通过邻区切换分析、现场测试等手段排查定位伪基站的方法。通过异频改造、降低功率等手段,可以有效规避、减弱伪基站干扰影响,保障用户业务感知。At present, the number of LTE pseudo base stations is increasing. The influences of pseudo base stations’ interference on network coverage and service quality are investigated, and a method to check and localize pseudo base stations based on adjacent cell handover analysis and on-spot test is proposed. By reforming differ-frequency and reducing power, the influences of pseudo base stations’ interference can be effectively avoided and weakened to guarantee the user service perception.
