摘　　要：在目前4G网络的VoLTE业务中,快速准确识别用户通话感知中的掉话、通话断续、单通等问题,并精准定位问题原因,是非常困难的事情。通过基于移动核心网的端到端XDR话单记录数据,结合无线侧MDT测量数据中的RSRP、RSRQ、SINR以及经纬度数据可实现快速高效的问题识别与问题原因定位,提升VoLTE用户业务感知问题的优化效率。In the current 4G network VoLTE service, IT is very difficult to quickly and accurately identify the dropped calls, intermITtent calls, one-way communication and other problems in the user’s call perception, and accurately locate the cause of the problem. Through the end-to-end XDR bill recording data based on the mobile core network, combined wITh the rsrp, rsrq,SINR and longITude and latITude data in the MDT measurement data on the wireless side, IT can realize fast and efficient problem identification and cause posITioning, and improve the optimization efficiency of the service perception problems of the VoLTE users.
