During the first audio/video call between the first terminal and the second terminal, the communication resources (such as a camera, a display screen, a speaker, a microphone, etc.) of the first terminal are in an occupied state. At this time, if an audio/video call request based on a mobile communication network of a third terminal is received, when a user selects to answer the audio/video call request based on the mobile communication of the third terminal through a first terminal, the first terminal suspends the first audio/video call with a second terminal, namely, a terminal application corresponding to the first audio/video call is notified to release audio/video call resources, and enters a suspended mode, and when the terminal application corresponding to the first audio/video call resources receives the notification of the first terminal about releasing the resources, the following steps are executed:
releasing communication resources such as a camera, a display screen, a loudspeaker and a microphone;
turning to the background and pausing the decoding of the received audio/video data, for example, the terminal application can directly discard the received audio/video data;
the connection relationship is maintained with the video communication server corresponding to the first audio/video call, for example, the terminal application may use other signaling such as heartbeat, or may otherwise maintain a long connection relationship with the video communication server corresponding to the first audio/video call.
After the terminal application completes the steps, the first terminal confirms that the call resources are released, and then the first terminal can establish a second audio/video call with the third terminal.
S12, when the first terminal exits the second audio/video call with the third terminal, the first audio/video call with the second terminal is resumed.
Specifically, in step S12, the resuming the first audio/video call with the second terminal specifically includes: the first terminal sends an end suspend command to the terminal application corresponding to the first audio/video call,

optionally, in step S22, the method further includes that the network device directly discards the received peer audio/video data sent by the video communication server corresponding to the first audio/video call.
Optionally, in step S22, the method further includes the network device sending the specified first audio/video information to the video communication server corresponding to the first audio/video call.
In this embodiment, since the first terminal is performing the first audio/video call based on the terminal application with the second terminal, and the first terminal adopts the data connection based on the mobile communication network, the data traffic of the first audio/video call is forwarded through the network device. After the network device sends a call request of the third terminal to the first terminal in the call and receives a message returned by the first terminal and successfully establishing the session with the third terminal, the network device suspends applying the pronunciation/video information transfer to the terminal corresponding to the first audio/video call or replaces the pronunciation/video information transfer with a blank frame. Meanwhile, the network device still receives the opposite-end audio/video data sent by the video communication server corresponding to the first audio/video call, and the network device can directly discard the received data. Because the session between the first terminal and the third terminal is successfully established, the first audio/video call between the first terminal and the second terminal is subjected to data transmission suspension, and the user of the second terminal does not know that the communication suspension is caused by a network problem or other problems, the network equipment sends the appointed first audio/video information to the video communication server corresponding to the first audio/video call so as to prompt the user of the second terminal that the first terminal at the opposite end of the user of the second terminal is carrying out another call and prompt the user of the second terminal to wait, so that the user of the second terminal is prevented from actively hanging up.

(5'): and the user data functional entity UPF recovers to forward the audio and video information from the video communication server to the video communication application, and simultaneously waits for the audio and video information from the video communication application and forwards the audio and video information to the video communication server.
(6'): the user data function UPF confirms to the session management function SMF that the operation specified by the command has been completed.
(7'): the session management function entity SMF returns a session recovered message to the UE.
(8'): the UE sends an end suspend command to the built-in video communication application.
(9'): and the UE restarts decoding the received audio and video information. And re-occupies the previously released resources (what was previously released and what was now occupied). And transmits the audio-video information to the video communication server.
Embodiment 3-embodiment 7 provide a terminal, an apparatus, a network device, a user data function entity, and a system for 5G network communication, wherein when a voice or video call based on a mobile communication network enters, voice or video communication based on an application is automatically suspended. Specifically, the terminal suspends the first audio/video call, notifies the terminal application to release resources and enters a suspended mode, or a user data function entity UPF corresponding to the first audio/video call in the network device suspends the application of forwarding audio/video information to the terminal or replaces the audio/video information with blank frames according to a pause audio/video call command sent by a session management function entity, and sends a specified audio/video call replacement content to the video communication server and discards the specified audio/video information. And automatically resuming the suspended voice or video communication based on the application program after the voice or video call based on the mobile communication network is ended. Specifically, the terminal resumes the first audio/video call, notifies the terminal application to end suspension, or the user data functional entity UPF sends a specified audio/video prompt message to the video communication server according to the resume audio/video call command sent by the session management functional entity, and resumes forwarding data to the terminal application. Therefore, the interruption of the first audio/video call between the first user terminal and the second user terminal can not be caused, and the problem that when two user terminals are carrying out audio/video call based on the application program in the prior art and the first user terminal adopts the data connection of the mobile communication network, when a third user terminal calls the first user terminal based on the audio/video chat request of the mobile communication network, the communication between the first user terminal and the second user terminal can be interrupted can be solved.
It will be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
