under a condition that a request of a video call initiated by a calling terminal is received, iterating over the call status of each type of video call in the video call status table to determine whether the current terminal is in the video call state; under a condition that the current terminal is in the video calling state, obtaining a first communication type of a current video call and a second communication type of the video call initiated by the calling terminal; under a condition that the first communication type is different from the second communication type, then generating a prompt message on a current call interface, wherein the prompt message is configured to prompt the request of the video call initiated by the calling terminal; and under a condition that a response operation to the request of the video call is received, switching a current video call to a video call of the second communication type to establish a video call connection with the call terminal. ### Claim 8 (depends on 7) The non-transitory computer-readable storage medium of claim 7, wherein after the operation of switching the current video call to the video call of the second communication type, the operations further comprise: determining the call status in the video call status table as a target video call being in a calling state;
