<p>A method, a system and a device to achieve intercommunication of a multimedia communication system are disclosed. they, in the case of the intercommunication of at least one side utilizing a H.245 protocol to control media stream, include: logic channel open information with logic channel direction information is reported to a media controller by a media processor after the media processor makes agreement for H.245 with terminals of the H.245 side, an opened logic channel is recognized as either receiving or sending based on the logic channel open information by the media controller, then, mapping relation between the logic channel of the H.245 side and the media stream of the other side intercommunicated is modified by the media processor with indication of the media controller, thereby, the intercommunication will be achieved. According to the present invention, due to the logic channel direction information included, the opened logic channel is recognized as either receiving or sending by the media controller, and the mapping relation between the logic channel of the H.245 side and the media stream of the other side intercommunicated is modified by the media processor with indication of the media controller correctly, thereby the intercommunication will be ensured to be achieved successfully.</p> |
