Problems solved by technology

[0032] The technical problem to be solved by the present invention is to overcome the problem that the user cannot provide unregistered services because the S-CSCF allocated by the user is unavailable in the existing IMS implementation, especially the problem that the PSI cannot be realized, and provide a session processing in the IMS The method and query call session control function module supports S-CSCF reselection during the called process, thereby reducing the risks existing in network operation, enhancing the reliability of the IMS network, and improving user satisfaction

Embodiment 1

[0117] As shown in Figure 4, the S-CSCF reselection is realized during the called process of the user, and the reselected S-CSCF functions normally, and the user does not initiate the registration process during the reselection period; the called home domain I-CSCF receives The processing flow for the called INVITE request is as follows:

[0118] 1. The I-CSCF forwards the INVITE request to the S-CSCF returned by the HSS (S-CSCF1 in the figure), but the S-CSCF1 does not respond, and it is concluded that the S-CSCF1 is faulty;

[0119] 2. The I-CSCF explicitly requests the HSS for the capability set information of the S-CSCF;

[0120] 3. If the HSS check passes, the I-CSCF performs S-CSCF reselection according to the returned capability set information, starts a timer, and forwards the INVITE request to the reselected S-CSCF (ie S-CSCF2);

[0121] 4. After reselection, S-CSCF2 requests to HSS to download user data. After receiving the request, HSS finds that the S-CSCF name co...

Embodiment 2

[0126] As shown in Figure 5, the user realizes the S-CSCF reselection during the called process, but the user initiates the registration process again during the reselection period, and the S-CSCF reselected during the registration process is the same as the S-CSCF during the called process. The CSCF is different, and the processing flow is as follows:

[0127] 1. The called home domain I-CSCF receives the called INVITE request;

[0128] 2. The I-CSCF forwards the INVITE request to the S-CSCF returned by the HSS (that is, S-CSCF1), but the S-CSCF1 does not respond, and it is concluded that the S-CSCF1 is faulty;

[0129] 3. The I-CSCF explicitly requests the HSS for the capability set information of the S-CSCF;

[0130] 4. If the HSS check passes, the I-CSCF performs S-CSCF reselection according to the returned capability set information, and forwards the INVITE request to the reselected S-CSCF2;

[0131] 5. At this time, the user initiates registration again. Since the S-CS...

Abstract

This invention involves a kind of conversation dealing method and I-CSCF module. When the S-CSCF is detected by the called attribution domain I-CSCF module or the contracted users server to be in the useless condition in the route process, the contracted users server will send to the I-CSCF the S-CSCF Competence Set information; after it receives the Competence Set information, I-CSCF will choose another S-CSCF, then the subsequent user will be called to the chosen S-CSCF to process. This invention resolves the problem that because of the accident in the S-CSCF, it cannot supply the user with the registering business, especially in the PSI case. As the result, the risk in the net operation is reduced, the reliability of the IMS network is enhanced, and the user satisfaction is improved.

Description

technical field [0001] The invention relates to the technical field of IP-based multimedia subsystem (IMS), in particular to a session processing method and query call session control function module in the IP-based multimedia subsystem (IMS). Background technique [0002] With the development of broadband network, mobile communication is not limited to traditional voice communication, but through the communication with data services such as presence, short message, web page (WEB), location information, push service (PUSH) and file sharing, etc. Combined, mobile communication can realize services of multiple media types such as audio, video, picture and text, so as to meet various needs of users. [0003] For example, short message services can provide instant messaging, chat rooms, and multimedia short message services; video services can provide services such as entertainment, multimedia information, and daily communication; e-commerce services can provide product catalogs...
