Embodiment Construction

[0027] Such as figure 1 As shown, the conference list subscription and notification method based on the SIP protocol of the present invention includes:

[0028] Step S1. Firstly, the user logs into the video conferencing system through a WEB browser, and makes a conference list subscription request;

[0029] Step S2, the conference list subscription request is forwarded to the subscription server of the video conference system through the proxy server;

[0030] Step S3, the subscriber server of the video conferencing system forwards the user's conference list notification to the user through the proxy server;

[0031] Step S4. When the meeting list information of the video conferencing system changes, the subscriber server actively forwards the change information notification of the user's meeting list to the user through the proxy server, wherein the change information only includes information that has changed since the last notification.

[0032] Such as fi...

Abstract

The invention provides a conference list subscription and notification method based on a SIP, which comprises the steps that: S1, firstly, a user logs in a video conference system by a WEB browser andcarries out a conference list subscription request; S2, the conference list subscription request is forwarded to a subscription server of a video conference system through a proxy server; and S3, thesubscription server of the video conference system forwards a conference list notification of the user to the user through the proxy server, wherein a conference list is notified by a conference-listevent packet of an XML file, the event packet only includes configuration information of conferences and allows the user to subscribe conference list information, both a notifier and a subscriber need to support an application / conference-list+xml data format, and a root element of the XML file is <conference-list>. according to the method provided by the invention, in the premise of ensuring integrity and readability of the conference list information, efficiency of transmitting useful information is improved, and a great quantity of server resources are saved.

Description

technical field [0001] The invention relates to the field of video conferencing, in particular to a method for subscribing and notifying a conference list based on the SIP protocol. Background technique [0002] A conference technology based on a SIP protocol (Session Initiation Protocol, Session Initiation Protocol) has become a mainstream technical standard of a video conference system. Compared with H.323, the structure of SIP protocol is simple and clear, and it can build a complex video and voice system at a lower cost. The SIP protocol has become the core control protocol for the next generation network (NGN: NextGenerationNetwork). At the same time, the standardization of the SIP protocol and its applications is also actively underway, including the standardization of centralized multimedia conferences led by the IETF SIPPING working group and the venue control and CPCP (Conference Conference) led by the XCON working group. Policy Control Protocol) standardization w...
