Abstract
A method, an apparatus, and a system for processing registration backup data are provided. The method includes: a Serving Call Session Control Function (S-CSCF) receives a request from a User Equipment (UE) and judges whether the request carries multi-registration information so as to decide whether to add multi-registration indication information into a Server Assignment Request (SAR) message sent to a Home Subscriber Server (HSS), which then performs operations according to whether the SAR message carries the multi-registration indication information. According to the application, unnecessary signaling interactions and unnecessary data processing between the HSS and the S-CSCF can be avoided, thereby reducing the signaling load, and saving system resources.
Claims29
A method for processing registration backup data comprising:
- receiving, by a serving call session control function (S-CSCF), from a user equipment (UE), a first registration request message that carries a user identity and multi-registration information;
- determining, by the S-CSCF, according to the multi-registration information, that the first registration request message is an initial registration request relating to a multi-registration;
- and
- obtaining, by the S-CSCF, registration backup data associated with the user identity from a home subscriber server.
A method for processing registration backup data, the method comprising:
- receiving, by a serving call session control function (S-CSCF), from a user equipment (UE), a first registration request message that carries a user identity and multi-registration information;
- determining, by the S-CSCF, according to the multi-registration information, that the first registration request message is an initial registration request relating to a multi-registration;
- requesting, by the S-CSCF, registration backup data from a home subscriber server associated with the user identity;
- and
- receiving, by the S-CSCF, from the home subscriber server, the registration backup data associated with the user identity to the S-CSCF.
An internet protocol multimedia subsystem (IMS) network comprising a serving call session control function (S-CSCF) and a home subscriber server,
- wherein the S-CSCF is configured to:
- receive a first registration request message from a user equipment (UE) that carries a user identity and multi-registration information;
- determine, according to the multi-registration information, that the first registration request message is an initial registration request relating to a multi-registration;
- and
- request, from the home subscriber server, registration backup data associated with the user identity,
- wherein the home subscriber server is configured to send registration backup data associated with the user identity to the S-CSCF based on the request from the S-CSCF.
An internet protocol multimedia subsystem (IMS) network comprising a serving call session control function (S-CSCF) and a home subscriber server,
- wherein the S-CSCF is configured to:
- receive a first registration request message from a user equipment (UE) that carries a user identity and multi-registration information;
- determine, according to the multi-registration information, that the first registration request message is an initial registration request relating to a multi-registration;
- and
- obtain, from the home subscriber server, registration backup data associated with the user identity;
- and
- wherein the home subscriber server is configured to send registration backup data associated with the user identity to the S-CSCF based on the request from the S-CSCF.
A serving call session control function (S-CSCF) apparatus comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor and having program instructions stored thereon that, when executed by the at least one processor, cause the apparatus to:
- receive, from a user equipment (UE), a first registration request message that carries a user identity and multi-registration information;
- determine according to the multi-registration information, that the first registration request message is an initial registration request relating to a multi-registration;
- and
- obtain registration backup data associated with the user identity from a home subscriber server.
