Embodiment Construction

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

[0030] As shown in Figure 1, 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 the...

Abstract

Through Internet being connected to SIP proxy server, the SIP terminal with video service constructs self-OPTIONS message based on SIP in the said SIP terminal. URI in 'From'header field is identical to URI in 'To'header field in OPTIONS message, and interaction is carried out between self-OPTIONS message, 200 OK response message of carrying SDP message body and SIP proxy server to implement OPTIONS self query in video service. Implementing OPTIONS self query, the invention is able to realize some essential functions in video service including declaring capabilities of proxy server of equipment, querying capabilities of browsing terminal, or updating state of 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...
