Specifically, the first mobile terminal first receives a push response message sent by the target mobile terminal, which indicates that the target mobile terminal has already acquired the live video content required by the user from the server. And the first mobile terminal determines the Identity identification number (Identity, short for English: ID) of the target mobile terminal for pushing the live video content according to the pushing response message sent by the target mobile terminal. Assuming that the target mobile terminal X, the target mobile terminal Y and the target mobile terminal Z all play corresponding live video contents according to the requirements of different viewers, then the target mobile terminal X, the target mobile terminal Y and the target mobile terminal Z respectively send push response messages to the first mobile terminal, so that the first mobile terminal displays the IDs of the target mobile terminal X, the target mobile terminal Y and the target mobile terminal Z.

In this way, the user can know which target mobile terminals are associated with the first mobile terminal.

Secondly, in the embodiment of the present invention, after the first mobile terminal sends the video link to the target mobile terminal, the first mobile terminal may further receive a push response message sent by the target mobile terminal, and then the first mobile terminal displays an ID of the target mobile terminal according to the push response message, where the ID indicates the target mobile terminal associated with the first mobile terminal.
