The present invention discloses a method, a system, and a device for controlling a token for an auxiliary stream in a multi-point double-stream conference. In the multi-point double-stream conference, a Multipoint Control Unit (MCU) receives a token depriving request message, judges whether to execute the token depriving according to the identifier carried in the token depriving request message, and deprives the token when deciding to execute the token depriving. The solution of the present invention effectively solves the problem that the auxiliary stream token is held by a certain conference terminal for a long time and the sending of an emergent and important auxiliary stream is disturbed and provides for the control of the auxiliary stream token in a multi-point double-stream conference to facilitate the need of a user.
