Definitions
- the present invention relates to the field of communications, and in particular to a method and system for canceling a user.
- IP Multimedia Subsystem IMS
- 3GPP 3rd Generation Partnership Project
- SIP Session Initiation Protocol
- SIP Session Initiation Protocol
- the proposal of IMS complies with the trend of communication network convergence development.
- the main functional entities in the IMS system include: User Equipment (UE), Proxy call session control function (P-CSCF), and Interrogating call session.
- Control Function referred to as I-CSCF
- S-CSCF Serving call session control function
- HSS Home Subscriber Server
- AS Application Server
- the Public User Identity is the user ID that the user communicates in the IMS network. If an IMS public user ID is to be used for the session, the user must first register. The registration process is to carry out the location on the network.
- a Subscribe / Notify mechanism allows a network entity to subscribe to certain resource information. When the resource information changes, the network entity responsible for the resource can notify the subscriber. After the registration is successful, the UE, the P-CSCF, and the AS will establish a subscription for the user registration status to the S-CSCF. After the user registration status is changed, the S-CSCF can notify the P-CSCF, UE, and AS through the Notify message to ensure the entire network. Data consistency.
- a subscription/notification relationship established between a UE, a P-CSCF, an AS, and an S-CSCF when the registration status of the user changes, the S-CSCF actively sends a Notify notification message to notify UE, P-CSCF, AS. Therefore, the data of the entire network of the UE, the P-CSCF, the S-CSCF, the HSS, and the AS are consistent.
- the S-CSCF can actively log off the user for the operation and maintenance needs of the operator (such as blacklist, arrears, pirate call, user management, etc.). The S-CSCF actively cancels the user process in the IMS system, as shown in FIG.
- Step S202 The S-CSCF decides to actively log off an IMS user according to the local policy or the operation and maintenance requirement;
- Step S204 based on The established subscription/notification mechanism, the S-CSCF sends a notify request to the P-CSCF, the request is used by the S-CSCF to notify the UE to cancel the user, and the request message carries the public user identifier of the user only;
- Step S206 the P-CSCF forwards The notify request to the UE;
- Step S208 after the UE completes the logout logic, sends a response message of the notify request to the P-CSCF, such as 200 OK;
- Step S210 the P-CSCF forwards the notify response message to the S-CSCF;
- Step S212 based on the established The subscription/notification mechanism, the S-CSCF sends a notify request to the P-CSCF, the request is used by the S-CSCF to notify the P-CSCF to cancel the user, and the request message carries the public user identifier of
- Step SAR the request message carries the public user identifier of the user, and the HSS is notified to log off the user;
- Step S222 After the AS completes the processing logic, the AS sends a response message of the notify request to the S-CSCF, such as 200 OK.

Abstract
L'invention concerne un procédé et un système de fermeture de sessions d'utilisateurs, lesquels s'appliquent à des sous-sytèmes multimédia IP. Selon le procédé, une fonction de gestion de sessions d'appel de service (S-CFSC) reçoit d'un serveur d'application (AS) un message de notification indiquant de fermer les sessions d'utilisateurs, le message de notification portant un identificateur d'utilisateur public (S302). La fonction S-CSCF traite le message de notification et ferme les sessions des utilisateurs correspondant à l'identificateur d'utilisateur public (S304). La solution selon la présente invention résout le problème lié au fait que la fermeture de sessions d'utilisateurs effectuée activement par la fonction S-CSCF dans la technologie afférente ne répond pas aux exigences d'un projet de partenariat de troisième génération et d'opérateurs basés sur l'exploitation, la maintenance et la politique, de sorte que les exigences de l'opérateur en termes d'exploitation de maintenance et de politique peuvent être satisfaites et que les utilisateurs en bénéficient.
