Step 503, the second video conference management server obtains the state information of the video networking terminal in the video conference through the video networking node server.
In the embodiment of the invention, when the second video conference management server acquires the state information of the video networking terminal in the video conference, the second video conference management server can receive the conference signaling sent by the autonomous server and extract the state information of the video networking terminal from the conference signaling according to the signaling protocol of the autonomous server. The signaling protocol of the autonomous server and the content of the conference signaling sent by the autonomous server to the second video conference management server are not particularly limited. For example, the second video conference management server J2 receives the conference signaling M1, and extracts the state information T1 of the video networking terminal Z1 from the conference signaling M1. In this embodiment of the present invention, the state information of the video networking terminal in the video conference may include an offline state, a registration state, an online and idle state, an online and conference-ready state, an online and conference-non-conference state, and the like.
