Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Such as figure 1 Shown, the network structure of the present invention is:

[0031] (1) monitoring front end 11,12,13 links to each other with front end equipment agent 22 by network cable;

[0032] (2) front-end device agent 22 maintains database 221 locally, and this database records information relevant to monitoring front-ends 11, 12, 13;

[0033] (3) browsing terminals 21, 23 and front-end equipment agent 22 are connected with Internet 3 through NAT / Firewall or directly;

[0034] (4) SIP proxy server 4 must be directly connected with Internet 3, can guarantee like this that browsing terminal 21,23 and front-end equipment agent 22 are successfully registered on SIP proxy server 4;

[0035] (5) The database 5 is connected to the SIP proxy server 4, and the database 5 may be a local database of the SIP proxy server 4, or may be connected to ...

Abstract

The invention provides a method for realizing OPTIONS self-inquiry in video services based on the SIP protocol. self-OPTIONS message, the URI in the From header field and To header field in the OPTIONS message are the same, and interact with the SIP proxy server with the self-OPTIONS message and the 200OK response message carrying the SDP message body, and realize OPTIONS automatic Inquire. Adopting this method can realize OPTIONS self-inquiry in the video service, so as to realize some necessary functions in the video service: including the capability declaration of the device proxy server, the capability query of the browsing terminal, or the status update of the browsing terminal, etc.

Description

technical field [0001] The present invention relates to communication technology and information technology in the field of video business, especially a method for realizing OPTIONS self-inquiry in video business based on SIP protocol, by applying SIP (Session Initiation Protocol) to video business and its monitoring field, and using The OPTIONS method in SIP performs self-inquiry (self-OPTIONS), so that some necessary functions in the video service can be realized: including the ability declaration of the monitoring front-end or front-end equipment agent, the ability query of the browsing terminal or the status update of the browsing terminal, etc. . Background technique [0002] In recent years, with the widespread popularization of the Internet, and the rapid development of electronic technology, multimedia technology, digital image compression technology, transmission technology and market demand, the video business and its monitoring technology have also made great prog...
