| 摘 要： | NSA组网方式下语音相较于普通VoLTE存在终端上行功率收缩问题，导致NSA语音感知不佳，5G驻留能力不强。本文通过对NSA语音用户上行功率收缩问题的深入研究和剖析，确认了造成语音感知不佳的关键原因和解决策略。经实践应用，能够有效解决NSA语音感知不佳的问题，对NSA网络业务质量提升和5G驻留能力增强起到了积极的促进作用。

| Abstract: | In NSA networking, voice has the problem of terminal uplink power contraction. In this sense, user experience of voice services and the data residency in NSA networking is not good. This paper analyzes the uplink power shrinkage of NSA voice users, given the key reasons and solutions of voice perception. It has been proved by practice that the problem of voice perception is solved effectively. It also plays a positive role in improving the voice quality and the 5G resident capacity of NSA network. |
