The HSS performs operations according to whether the SAR message carries the multi-registration indication information, therefore avoiding unnecessary signaling interactions, reducing the signaling load, avoiding unnecessary data processing between the HSS and the S-CSCF, and saving system resources.

Abstract: A Serving Call Session Control Function (S-CSCF) receives a registration request message carrying an IMS Private User Identity (IMPI) and IMS Public User Identity (IMPU) pair. The S-CSCF determines: a lack of registration data corresponding to the IMPI and IMPU pair; and that the registration request message includes a reg-id parameter indicating that the registration request message relates to a multi-registration. The S-CSCF sends a Server Assignment Request (SAR) message to a Home Subscriber Server (HSS). The SAR message carries the IMPI and IMPU pair, a parameter for identifying that the SAR message relates to an initial registration of a user, and a multiple registration indication which indicates that the SAR message relates to a multi-registration associated with the IMPI and IMPU pair. The S-CSCF receives a Server Assignment Answer (SAA) message carrying registration backup data corresponding to the IMPI and IMPU pair from the HSS.

Abstract: A method for realizing an Internet protocol (IP) multimedia subsystem (IMS) disaster tolerance includes the steps as follows. An S-CSCF receives a user registration, and backs up necessary data which is required when a user service processing is restored on a storage entity in a network. An I-CSCF of user's home domain receives a service request of the user, and if it is found that the S-CSCF currently providing a service for the user fails, assigns a new S-CSCF to the user, and forwards the service request to the newly assigned S-CSCF. The newly assigned S-CSCF interrogates and acquires subscription data of the user and the necessary data backed up by the original S-CSCF from the storage entity, and then restores the user service processing according to the subscription data and the backup data. A device for realizing an IMS disaster tolerance is also provided.
