A method for multi-point conference control double secondary stream of tokens, system and device

The present invention relates to a method of communicating a multi-point double BACKGROUND conference control secondary stream of tokens, systems and equipment. When multiple double session token is occupied by the secondary stream and transmitting the venue where a first terminal, a second terminal venue token request denied, multipoint control unit MCU receives the token release message; MCU release message according to the token identifier carried in the operation determines whether a token deprivation; token depriving determined to execute the first conference terminal when the token depriving operation. Embodiments of the present invention, after the MCU receives the token release message, whether the token depriving operation may be performed according to the identifier carried in the message is determined, and when the token is determined to execute the operation deprivation, specific token is performed by MCU depriving operation, effectively solve the secondary stream token has long been a conference terminal and affect the sending urgent and important issue secondary stream to achieve a multi-point conference Shuangliu full control of the auxiliary flow token, to meet the needs of users.
