Method, apparatus, and system for disaster recovery of IMS
First Claim
1. A method for disaster recovery, comprising:
- obtaining, by a Call Session Control Function (CSCF), information of registered IP Multimedia Subsystem (IMS) Private User Identities (IMPIs) that are associated with an IMS Public User Identity (IMPU) in an IMS subscription transmitted by a network storage entity;
determining, by the CSCF, at least one DM that was received from the network storage entity is not registered in the CSCF, and based upon the determining, requesting user service configuration data of the IMPU and user backup data of IMPIs associated with the IMPU from the network storage entity; and
receiving, by the CSCF, the user service configuration data of the IMPU and the user backup data of the IMPIs associated with the IMPU in a response returned by the network storage entity, wherein the user service configuration data of the IMPU and the user backup data of the IMPIs associated with the IMPU is used by the CSCF for recovering a corresponding service.

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.

7. A Call Session Control Function, (CSCF), comprising:
-
at least one processor; a non-transitory memory in communication with the at least one processor, the memory including instructions executable by the at least one processor for performing the steps of; obtaining information of registered IP Multimedia Subsystem (IMS) Private User Identities (IMPIs) that are associated with an IMS Public User Identity (IMPU) in an IMS subscription transmitted by a network storage entity; determining at least one IMPI that was received from the network storage entity is not registered in the CSCF, and based on the determining, requesting the network storage entity for user service configuration data of the IMPU and user backup data of the IMPIs associated with the IMPU from the network storage entity; and receiving the user service configuration data of the IMPU and the user backup data of the IMPIs associated with the IMPU in a response returned by the network storage entity, wherein the user service configuration data of the IMPU and the user backup data of the IMPIs associated with the IMPU is used by the CSCF for recovering a corresponding service. - View Dependent Claims (8)

9. A network storage entity, comprising:
-
at least one processor; a non-transitory memory in communication with the at least one processor, the memory including instructions executable by the at least one processor for performing the steps of; sending information of registered EP Multimedia Subsystem (IMS) Private User Identities (IMPIs) that are associated with IMS Public User Identity (IMPU) in an IMS subscription to a Call Session Control Function (CSCF); receiving a request for user service configuration data of the IMPU and user backup data of the IMPU from the CSCF; and sending the user service configuration data of the IMPU and the user backup data of the IMPIs associated with the IMPU to the CSCF. - View Dependent Claims (10)
