摘　　要：无线通信为我们日常生活带来极大便利,但某些特殊场景长期或者规律性开启干扰器,对网络产生影响,导致用户语音感知较差。本文对高干扰场景下语音接入和保持等性能进行研究,确定不同业务下VoLTE语音质量拐点。通过底层理论研究,得出高干扰场景下的优化参数及优化策略,最终形成高干扰场景预干预机制。我们通过实践中不断验证,最终形成了高干扰场景预干预数据库和预干预机制,通过对高干扰场景进行预警和提前干预,实现提高VoLTE语音质量和用户感知的目标。Wireless communication brings great convenience to our daily life.However,some special scenes have long-term or regular open jammers,which have an impact on the network and lead to a not good voice experience.This topic studies the infl ection points of VoLTE quality in the different scenarios,studying the VoLTE performance of voice access and hold,in the high-interference scenarios.Through theoretical research,fi nding out the optimization strategies under high-interference scenarios,and forming a highinterference scene pre-intervention mechanism.We have formed a pre-intervention database and the preintervention process in the high-interference by a practical manner.We can improve voice quality and the user experience of the VoLTE quality by a method of the early warning and the intervention.

关 键 词：干扰 VoLTE语音质量拐点 预干预机制
