In addition, a plurality of system combinations (e.g., LTE or a combination of LTE-a and 5G, etc.) may be applied.

In some embodiments, the present disclosure proposes different communication modes. Among these are VoWiFi-based communications, voLTE-based communications, voNR-based communications. Different communication modes are described below.

VoWiFi-based communication: voWiFi refers to an operator providing voice services to users using WiFi hotspots. Through the VoWiFi technology, a user can use WiFi access to make and receive voice or video calls while using the mobile Internet.

VoLTE based communication: VOLTE is a high-speed wireless communication standard for mobile phones and data terminals. It is based on an IP Multimedia Subsystem (IMS) network, uses on LTE a configuration file tailored to the control plane and the media plane of the voice service, which enables the voice service to be transported as a data stream in the LTE data bearer network without the need to maintain and rely on a traditional circuit switched voice network.

VoNR-based communication: voNR is a target voice solution for 5G networks, and 5G-based voice services are called VoNR. Namely, the NR user can directly carry out voice service based on the NR network without falling back to the LTE network, so that higher-quality voice service experience and higher-rate data service experience are obtained.

Optionally, the first RSSI value is set by the terminal, or configured by the network device, or agreed by a communication protocol, which embodiments of the present disclosure do not limit. Alternatively, the first RSSI value is represented by Thresh RSSI high wifi, or by other means.

In some embodiments, the SNR of the reference signal in the second communication mode refers to an SNR obtained by performing SNR measurement on the reference signal by the terminal in the second communication mode. The SNR of the reference signal in the second communication mode refers to an SNR value obtained by the terminal measuring the reference signal based on wifi. Alternatively, the SNR of the reference signal of the second communication mode is represented by ms_snr_wifi, or by other modes.
