Method, Apparatus, and System for Disaster Recovery of IMS
First Claim
1. A method for disaster recovery, comprising:
- obtaining, when a redundant Call Session Control Function (CSCF) is triggered, by the redundant CSCF, user backup data of registered IP Multimedia Subsystem (IMS) Private User Identities (IMPIs) that are associated with IMS Public User Identities (IMPUs) and user service configuration data of the IMPUs in an IMS subscription from a network storage entity of a user; and
performing, by the redundant CSCF, a corresponding service according to the obtained user backup data of the registered IMPIs and user service configuration data of the IMPUs in the IMS subscription.

Abstract
A method, apparatus, and system for disaster recovery of an IP Multimedia Subsystem (IMS) are provided. The method includes: triggering a redundant Call Session Control Function (CSCF); obtaining, by the redundant CSCF, user backup data of registered IMS Private User Identities (IMPIs) that are associated with IMPUs and user service configuration data of IMS Public User Identities (IMPUs) in an IMS subscription from a network storage entity of a user; and recovering, by the redundant CSCF, a corresponding service according to the obtained user backup data of the registered IMPIs and user service configuration data of the IMPUs in the IMS subscription. With the present invention, the one-IMPU multi-IMPI, one-IMPI multi-IMPU, or multi-IMPI multi-IMPU service can be recovered, and this enables the user to have better service continuity experiences.

15. A Call Session Control Function (CSCF), comprising:
-
a disaster recovery data obtaining unit, adapted to obtain user backup data of registered IP Multimedia Subsystem (IMS) Private User Identities (IMPIs) that are associated with IMS Public User Identities (IMPUs) and user service configuration data of the IMPUs in an IMS subscription from a network storage entity of a user; and a disaster recovery processing unit, adapted to perform a corresponding service according to the user backup data of the registered IMPIs and the user service configuration data of the IMPUs in the IMS subscription that are obtained by the disaster recovery data obtaining unit. - View Dependent Claims (16, 17, 18)

19. A network storage entity, comprising:
-
a user data storing unit, adapted to store user service configuration data, user backup data for recovering user services, and information of a Call Session Control Function (CSCF) where a user is registered; a disaster recovery data transmitting unit, adapted to transmit the user backup data to a CSCF; a message encapsulating unit, adapted to encapsulate a response that carries information of one of registered IP Multimedia Subsystem (IMS) Private User Identities (IMPIs) and IMS Public User Identities (IMPUs); and a message sending unit, adapted to send the response that carries the information of one of the registered IMPIs and IMPUs to the CSCF. - View Dependent Claims (20)

21. A network storage entity, comprising:
-
a user data storing unit, adapted to store user service configuration data, user backup data for recovering user services, and information of a Call Session Control Function (CSCF) where a user is registered; and a disaster recovery processing unit, which comprises; a judging unit, adapted to judge whether to perform disaster recovery for a CSCF; and a data transmitting unit, adapted to transmit user backup data of registered IP Multimedia Subsystem (IMS) Private User Identities (IMPIs) that are associated with the user and user service configuration data of IMS Public User Identities (IMPUs) in an IMS subscription to a redundant CSCF by interacting with the redundant CSCF at least once if a judgment result of the judging unit is to perform disaster recovery for the CSCF. - View Dependent Claims (22)
