Problems solved by technology

[0004] The problem to be solved by the present invention is to overcome the adverse effects caused by the SIP terminal user registration period in the prior art, and then provide a method for detecting the online status of the terminal by the conference initiation protocol server, so that when the SIP terminal exits abnormally, the SIP server is in a Within the time less than the SIP terminal registration period, the online status of each SIP terminal can be obtained and updated in time, so that the SIP server can provide the terminal user with the due service in time after the SIP terminal exits abnormally

Embodiment Construction

[0014] The detailed implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, after the SIP terminal registers online, the message flow of the SIP server actively detecting the online status of the SIP terminal user includes the following steps:

[0016] Step 111: after the SIP terminal is powered on, periodically send a REGISTER registration request message to the SIP server;

[0017] Step 112: Since there is no user authentication information in the REGISTER message, the SIP server returns a 401 Unauthenticated response message to the SIP terminal;

[0018] Step 113: the SIP terminal sends a REGISTER request message with authentication information to the SIP server;

[0019] Step 114: the authentication is passed, and the SIP server returns a 200 OK response to the SIP terminal;

[0020] Step 115: If the registration cycle duration of the SIP terminal is longer than the detection time...

Abstract

The present invention provides conference originating protocol server to termination on-line state detection method. It contains after receiving SIP terminal logon request message and successfully responding, SIP server saving said terminal relevant positional information and active starting up detecting function to said terminal, according to detecting timer cyclically to make detecting to terminal; when SIP server receiving SIP terminal response message failing in detection procedure, then updating said terminal relevant positional information in data base; when receiving SIP terminal successful response message, ending this detection; when SIP server receiving SIP terminal cancellation message and successfully responding, then end cyclically detecting to said SIP terminal. The present invention can in time learn and update current SIP terminal on-line state in SIP server detecting period.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a technology for a SIP server to detect whether a SIP terminal is online. Background technique [0002] RFC3261 (Request for Comments: 3261, published in June 2002, section 10.1, pages 56-57) stipulates that SIP UA (SIP: Session Initiation Protocol, session initiation protocol; UA: User Agent user agent) after power-on A request to periodically register with the SIP server. If the SIP server does not receive the registration request message from the SIP terminal (ie SIP UA) within the registration period, the terminal location information related to the user is deleted from the database. [0003] When a SIP terminal is offline due to some reasons such as power failure or abnormal exit of the terminal program, it cannot send a logout request message to the SIP server network, and the SIP server will keep the terminal location related to the terminal user until the registrati...
