Embodiment Construction
[0046] The core idea of the present invention is: in the intercommunication scenario where at least one side uses the H.245 protocol to control the media flow, after the media processing device completes the H.245 negotiation with the terminal on the H.245 side, it reports to the media control device that contains Open logical channel information with logical channel direction information, the media control device recognizes the direction of the opened logical channel as receiving or sending according to the received open logical channel information, and instructs the media processing device to modify the logical channel on the H.245 side and communicate with the other Mapping relationship between media streams on one side to achieve intercommunication.
[0047] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferre...

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.
Description
technical field [0001] The invention relates to multimedia communication system intercommunication technology, especially a method for realizing multimedia communication system intercommunication. At least one side of the interoperable multimedia system adopts H.245 protocol to control media flow. Background technique [0002] A multimedia communication system refers to a network system that can provide multimedia sessions, such as audio and video communications. At present, there are many multimedia communication systems, such as: H.324 network using H.324, H.245, H.223 and other protocols; using H.323 protocol, H.225.0 protocol, H.245 protocol, real-time transport protocol / H.323 networks such as Real-time Transport Control Protocol (RTP / RTCP); IP Multimedia Subsystem (IMS) using Session Initiation Protocol (SIP), Session Description Protocol (SDP), RTP / RTCP, etc. [0003] This article is aimed at multimedia interworking scenarios where at least one side of the interopera...
