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。

关键词: 5G, VoWi-Fi, VoNR, VoLTE, 切换

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.

Key words: 5G, VoWi-Fi, VoNR, VoLTE, handover
