Abstract

The embodiment of the invention discloses a method for transmitting a conference control signaling. The method comprises the following steps: a device for transmitting a conference control signaling negotiates with an opposite device about the high-bandwidth conference control capability; if the negotiation is successful, the device transmits the information of a high-bandwidth conference controlchannel required for the device to the opposite device, wherein the high-bandwidth conference control channel is an idle channel other than bit rate allocation signal (BAS); after receiving the transmission allowance command from the opposite device, the device transmits the conference control signaling via the high-bandwidth conference control channel required for the device. The invention also discloses a device for transmitting a conference control signaling and a system thereof. The conference control signaling transmitting method can increase the transmission speed of conference control signaling during the multi-point conference process and improve the conference control efficiency.

Description

technical field [0001] The invention relates to network technology, in particular to a method and equipment for transmitting conference control signaling. Background technique [0002] With the rapid development of image and voice compression technology, computer technology and network technology, conference TV technology is becoming more and more mature, and its business has become an important development direction in the field of post and telecommunications. The H.320 protocol system is the protocol standard of the circuit-switched videoconferencing system. The H.221 protocol is a frame structure protocol in the H.320 protocol framework. It mainly defines how audio, video, data, control signaling, etc. are multiplexed into frame transmission formats, and subdivides the transmission channel of 64-1920kbps into speed Lower channels are suitable for the purpose of transmitting audio, video, data and information communication services. When the device is working in a multi...
