Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that in the prior art video conferencing system using the H.323 protocol, the conference initiator cannot order the conference terminal participating in the low-level conference to forcibly withdraw from other conferences and then participate in the high-level conference

Embodiment 1

[0050] Such as figure 1 As shown, as an embodiment of the present invention, a method for expanding H.323 signaling to realize forced demolition of a video conference includes the following steps:

[0051] S1: Divide the conference levels for the conferences controlled by each multi-point control unit and define and store the priorities of the conferences of each level. For example, the 15 conferences subordinate to the connected multi-point control unit are set as conference levels 1-15, and the priority of conference 15 is higher than that of conference 1.

[0052] S2: Define and store the forced demolition instruction, wherein the forced demolition instruction further includes:

[0053] (1) Request a forced demolition command, which is used to ask the conference terminals that have participated in other conferences whether to join the new conference;

[0054] (2) Executing a forced demolition command, which is used to order the conference terminals that have participated ...

Embodiment 2

[0061] As an embodiment of the present invention, on the basis of the above-mentioned embodiment 1, in the step S3, the new conference establishment signaling specifically includes:

[0062] (1) Adding the conference level, the request for forced demolition instruction and the relevant information of the multipoint control unit to the signaling for establishing a conference to form the first signaling for establishing a conference;

[0063] (2) Adding the conference level, execution forced demolition command, and related information of the multi-point control unit to the conference establishment signaling to form a second conference establishment signaling.

[0064] In the method for implementing forced demolition of a video conference by extending H.323 signaling, the extended conference establishment signaling includes first conference establishment signaling and second conference establishment signaling. Different operations are performed on conference terminals in differen...

Embodiment 3

[0066] As an embodiment of the present invention, on the basis of the above-mentioned embodiment 2, the sending the request for forced release instruction to all terminals specifically includes: ordering the multi-point control unit to send the first conference establishment with the request for forced release instruction attached Signaling to all conference endpoints that need to join a new conference

[0067] The method for implementing forced demolition of a video conference by expanding H.323 signaling is to order the multipoint control unit to send the first conference establishment signaling to all conference terminals that need to participate in a new conference, and to inform the conference terminals to hold a new conference Notifications should be carried out through inquiries to avoid affecting higher-level meetings.

Abstract

The invention discloses a method and a system for expanding an H. 323 signaling to realize video conference canceling. A video conference video scheduling system and a multi-point control unit can identify conference levels by dividing the conference levels, and conference terminals are enabled to identify a corresponding canceling command by defining the canceling command. An established conference signaling can be enabled to comprise related information of the conference level of a new conference, the canceling command, and the multi-point control unit to which the new conference belongs by expanding and establishing the conference signaling at the multi-point control unit, so the conference terminals already participating other conferences can conveniently identify the new conference and the multi-point control unit. After receiving the canceling command, the conference terminals already participating other conferences respond the canceling command and send the level and name of the participated conferences. The canceling command is sent and executed by comparing the levels of the participated conferences of the conference terminals, and the canceling command is executed in a mode that the conference terminals are ordered to quit the participated conferences, thus realizing the conference canceling.

Description

technical field [0001] The invention relates to a video conference control technology. Specifically, it relates to a method and system for expanding H.323 signaling to realize video conference forced demolition. Background technique [0002] As a modern multimedia communication tool, video conferencing enables different people to participate in the same meeting at different locations; and through the conference management function of the multipoint control unit (MCU), participants can use the conference terminal to see the speaker The image of the conference site and hear the content of the speaker's speech, and the speaker can also see and hear the image and sound of the specified conference site. The H.323 protocol is a set of standards developed by ITU-T (International Telecommunication Union) to provide real-time audio, video and data communication on packet networks. It is based on the general and open computer network communication technology basics, allowing audio, ...
