Below, with reference to the embodiment of FIG. 1 , the related technologies in the background technology will be further described in detail. For details, please refer to the embodiment of FIG. 1 .

FIG. 1 is a schematic flowchart of a communication method in the related art provided by the present application. As shown in Figure 1, the communication method in the related art includes:

S101. After successfully registering with the NR network, the terminal device obtains the call identifier in the access and mobility management function (Access and Mobility Management Function, AMF) field according to the emergency call triggered by the user.

S102. After determining that the call identifier indicates to send a call request to the network device, the terminal device sends a call request to the network device, where the call request includes an emergency fallback identifier (emergency eps fallback).

S103, the terminal device ends the emergency call.

S104: The network device sends a first indication to the terminal device, where the first indication is used to instruct the terminal device to switch from the NR network state to the LTE network state.

S105, the terminal device switches from the NR network state to the LTE network state according to the first instruction.

S106, the network device sends a second indication to the terminal device after a preset duration, where the second indication is used to instruct the terminal device to switch from the LTE network state to the NR network state.

S107, the terminal device switches from the LTE network state to the NR network state according to the second instruction.

In the related art, after the terminal device ends the emergency call, the terminal device needs to switch from the NR network state to the LTE network state according to the first instruction, and before the terminal device receives the second instruction, the terminal device waits in the LTE network state for a preset time period , resulting in a relatively low NR occupation of the terminal equipment on the network. In practical applications, when the terminal device is in the NR network state, the terminal device displays the 5G icon corresponding to the NR network state, and when the terminal device is in the LTE network state, the terminal device displays the 4G icon corresponding to the LTE network state. Therefore, in the related art, after the terminal device ends the emergency call, the terminal device waits for a preset time in the LTE network state, which causes the terminal device to display the 4G icon within the preset time, resulting in poor user experience.

Further, in the related art, after the emergency call triggered by the user for the first time and the emergency call is quickly ended, the terminal device switches from the NR network state to the LTE network state, and then switches from the LTE network state to the NR network state; after the user triggers the emergency call again After the emergency call is made and the emergency call is quickly ended, the terminal device switches from the NR network state to the LTE network state again, and then switches from the LTE network state to the NR network state. Therefore, after the emergency call triggered by the user for many times and the emergency call is quickly ended, the terminal device is repeatedly switched from the NR network state to the LTE network state, and then switched from the LTE network state to the NR network state, which further leads to the NR of the terminal device. The network is relatively low.
