Abstract: A method and a system for recording audio/video data, including: a first User Equipment (UE) sends an audio/video recording request to indicate a second UE that audio/video data of the second UE will be recorded, in which the first UE is configured to record the audio/video data of the second UE; the second UE determines whether the audio/video data is allowed to be recorded, and sends an audio/video recording response indicating the audio/video data is allowed to be recorded to the first UE, when the second UE determines the audio/video data is allowed to be recorded; the first UE records the audio/video data from the second UE, when the first UE receives the audio/video recording response. The method and system may complete a communication procedure, which is associated with an audio/video recording between different UEs.
