Signaling interaction method and device based on tele-presence system

The invention provides a signaling interaction method and a signaling interaction device based on a tele-presence system. The method comprises the following steps that: a multipoint control unit (MCU) or a tele-presence terminal receives a remotely constructed capacity set message which carries an associated relation between all remotely supported media and position information; the MCU or the tele-presence terminal performs capacity interaction with a remote terminal according to the position information of the media supported by the MCU or the tele-presence terminal and the received associated relation; and the MCU or the tele-presence terminal and the remote terminal respectively open logic channels, which is acquired by the interaction corresponding to the position information of the public capacity. By the technical scheme, the control of the tele-presence terminal can be simplified, and combination of the tele-presence terminal and the conventional meeting television is realized.
