摘　　要：随着5G网络发展和终端的成熟,VoNR已经成为5G语音业务的最优解决方案。受700 MHz干扰的影响,VoNR语音客户在该频段驻留时,仍然存在接续成功率低和语音感知差等问题。本文通过研究700 MHz不同干扰场景下的VoNR语音的感知拐点,找到了不同干扰场景下VoNR语音的驻留策略,为推进VoNR语音快速部署和5G语音质量快速提升提供了依据。With the development of 5G networks and the maturity of terminals,VoNR has become the optimal solution for 5G voice services.VoNR voice customers still have problems such as low connection success rate and poor voice perception when they reside in the interfered 700 MHz frequency band.In this paper,by studying the perceptual infl ection point of VoNR mobile customers in diff erent interference scenes at 700 MHz network,it also found the VoNR speech dwell strategy under diff erent interference scenes.The paper provides evidence for the rapid improvement of 5G voice quality,and also pushing VoNR voice scale.
