摘　　要：针对移动通信过程中位置更新导致的寻呼失败问题进行有效分析,并提出优化方案。首先发现未接通异常事件;然后通过核心网网管信令全流程分析未接通原因,并介绍问题处理过程和解决方案;最后针对这种未接通异常事件,采用参数调整方法,可以有效减少TAU过程,从而达到降低TAU过程与CSFB冲突的研究目标。The paging failure resulted from location update in mobile communications was effectively elaborated and the optimization scheme was proposed. Firstly, the disconnected abnormal event was found out. Then, the cause for disconnection was analyzed via the complete process of core network management signaling. In addition, the problem processing and the solutions were introduced. Finally, aiming at this disconnected abnormal event, the TAU process was reduced effectively by adopting the parameter adjustment method. Thus, the conflict between the TAU process and CSFB was decreased.
