摘要

通过参考VoWi-Fi在4G下的业务组网架构和互操作方案，对VoWi-Fi在5G下的业务组网架构和互操作方案进行研究和差异性分析。在网络和终端产业链尚不支持独立组网（SA）和Wi-Fi互操作的现状下，提出了过渡期的互操作变通方案，并给出了终端和网络侧的配置建议，实现基于5G网络的VoWi-Fi与VoLTE互操作，确保用户无感知。通过实际测试验证了该方案的可行性，为VoWi-Fi的实际部署提供了参考。

Abstract

By referring to the service network architecture and interoperation scheme of VoWi-Fi under 4G

the differences of the service network architecture and interoperation scheme of VoWi-Fi under 5G were studied and analyzed.Under the current situation that the network and terminal industry chain didn’t support the interoperability between standalone (SA) and Wi-Fi

a workaround scheme for interoperation in the transitional period was proposed

and the terminal and network side configuration suggestions were given to realize the interoperation between VoWi-Fi and VoLTE based on 5G network to ensure that users were unaware.The feasibility of this scheme was verified by practical tests.It provides reference for the actual deployment of VoWi-Fi.
