摘　　要：针对LTE语音承载在2G/3G网络的情况下,提出了一种方法可快速探测和发现基于4G用户分布的、有4G网络覆盖而2G/3G网络存在覆盖空洞和弱覆盖的问题,并精准定位语音回落空洞区域,为2G/3G网络覆盖规划、设计及完善指明位置,提高了问题发现和解决的效率。In the case of LTE voice carried in the 2G/3G network,a method is proposed to detect and discover the problem of coverage hole and weak coverage of 2G/3G network with 4G network coverage based on 4G user distribution.The method can accurately position the CSFB hole area,and specify the location for the planning,design and improvement of 2G/3G network coverage,which can improve the efficiency of problem detection and resolution.
