[0150] In some embodiments, the present disclosure proposes different communication methods, including VoWiFi-based communication, VoLTE-based communication, and VoNR-based communication. The following describes the different communication methods.

[0151] VoWiFi-based communications: VoWiFi refers to operators using WiFi hotspots to provide users with voice services. Through VoWiFi technology, users can use WiFi access to make and receive voice or video calls while using mobile Internet.

[0152] VoLTE-based communications: VoLTE is a high-speed wireless communication standard for mobile phones and data terminals. Based on the IP Multimedia Subsystem (IMS) network, it uses specialized profiles for the control plane and media plane of voice services over LTE. This allows voice services to be transmitted as data streams over the LTE data bearer network, eliminating the need to maintain and rely on traditional circuit-switched voice networks.

[0153] VoNR-based communications: VoNR is the target voice solution for 5G networks, and 5G-based voice services are called VoNR. This means NR users can conduct voice services directly over the NR network without falling back to the LTE network, resulting in a higher-quality voice experience and higher-speed data services.
