Abstract

The present invention discloses a method for realizing user identity association, the method comprising: setting an equivalent behavior user identifier in a Home Subscription Server (HSS); associating IMS Public User Identities (IMPUs) with the equivalent behavior through the set equivalent behavior user identifier. The present invention also discloses a system and a device realizing user identity association. According to the embodiments of the present invention, the association of the IMPUs with the set equivalent behavior is realized, which improves the user experiences.

Claims

1. A method for identifying Public User Identity, comprising:

setting an equivalent behavior user identifier in a Home Subscription Server (HSS);

identifying IP Multimedia Subsystem (IMS) Public User Identities (IMPUs) with the equivalent behavior through the set equivalent behavior user identifier, wherein the IMPUs with the equivalent behavior are linked to a same Service Profile (SP) and have same service data;

adding, by the HSS, an attribute indicating a set of IMPUs to which an IMPU belongs, to a Public Identity class in an SP transmitted to a Serving Call Session Control Function (S-CSCF);

indicating set of IMPUs with the equivalent behavior to which each IMPU belongs by assigning a value to the attribute; and

presenting, by the HSS, the identifying information to the S-CSCF, by the SP carrying the indication.

2. The method of claim 1, wherein the IMPUs with the equivalent behavior belong to a same Implicitly Registered Public User Identity Set (IRPUIS).

3. The method of claim 1, wherein the setting the equivalent behavior user identifier in a HSS comprises:

setting in an HSS an indication used for indicating a set of IMPUs with the equivalent behavior.

4. The method of claim 3, wherein the setting in an HSS an indication used for indicating a set of IMPUs with the equivalent behavior comprises:

adding a type of data in the HSS, wherein the type of data is configured to indicate an Alias Public User Identity Set.

5. The method of claim 1, wherein the setting the equivalent behavior user identifier in the HSS comprises:

setting with an IMPU of the HSS an indication used for indicating a set of IMPUs with the equivalent behavior to which the IMPU belongs;

or

setting with an IMPU of the HSS an indication used for indicating that the IMPU belongs to a set of IMPUS with the equivalent behavior.

6. The method of claim 1, wherein the SP refers to a set of user subscription data related to a service.

7. The method of claim 1, wherein the same service data refers to the same forwarded to address information or same representation information.

8. The method of claim 1, wherein the method further comprises:

presenting, by the HSS, identifying information to the S-CSCF via a Cx interface.

9. The method of claim 1, transmitting, by a requesting entity, a subscription to notification of an event to the S-CSCF;

presenting, by the S-CSCF, the identifying information of the IMPUs with the equivalent behavior to the requesting entity by carrying the identifying information in the subscribed event packet, according to the subscribed notification of the event;

wherein the requesting entity is a User Equipment (UE), an Application Server (AS) or a Proxy-CSCF (P-CSCF).

10. The method of claim 1, wherein the method further comprises:

requesting, by an AS, the IMPUs with the equivalent behavior from the HSS; and

presenting, by the HSS, the IMPUs with the equivalent behavior to the AS, according to the request.

11. The method of claim 10, wherein the step of requesting, by the AS, the IMPUs with the equivalent behavior from the HSS comprises:

indicating, by the AS, an identity type of the equivalent behavior using an identity set attribute value pair (AVP), carrying the identity set AVP indicating the identity type of the equivalent behavior in the requesting message and transmitting the identity set AVP to the HSS;

the step of presenting, by the HSS, the IMPUs with the equivalent behavior to the AS according to the request comprises;

presenting, by the HSS, IMPUs with the equivalent behavior as the IMPU in the request message to the AS, according to the identity type of the equivalent behavior as indicated in the request message.

12. A device for identifying user identity, comprising an indication setting module, an indication presenting module, and an information presenting module, wherein:

the indication setting module is configured to set an equivalent behavior user identifier in an HSS; and

the indication presenting module is configured to identify IMPUs with the equivalent behavior using the equivalent behavior user identifier set by the indication setting module;

wherein the IMPUs with the equivalent behavior are linked to a same Service Profile (SP) and have same service data;

the information presenting module is configured to add an attribute indicating a set of IMPUs to which an IMPU belongs, to a Public Identity class in an SP transmitted to a Serving Call Session Control Function (S-CSCF);

indicate set of IMPUs with the equivalent behavior to which each IMPU belongs by assigning a value to the attribute; and

present the identifying information to the S-CSCF, by the SP carrying the indication.

13. The device of claim 12, wherein

the indication presenting module is configured to provide information of the indicated IMPUs with the equivalent behavior to the information presenting module and present identifying information of the IMPUs with the equivalent behavior to a requesting entity, according to the information of the indicated IMPUs with the equivalent behavior provided by the indication presenting module.

14. A system for identifying user identity comprising an HSS and a first requesting entity, wherein:

the HSS is configured to identify IMPUs with equivalent behavior and to transmit association information of the IMPUs with the equivalent behavior to the first requesting entity by carrying the information in a message, wherein the IMPUs with the equivalent behavior are linked to a same Service Profile (SP) and have same service data; and

the HSS is configured to add an attribute indicating a set of IMPUs to which an IMPU belongs, to a Public Identity class in an SP transmitted to a first requesting identity;

indicate set of IMPUs with the equivalent behavior to which each IMPU belongs by assigning a value to the attribute; and

present, by the HSS, the identifying information to the first requesting identity, by the SP carrying the indication

the first requesting entity is configured to parse the message from the HSS and to obtain the association information of the IMPUs with the equivalent behavior from the message.

15. The system of claim 14, wherein the HSS comprises an indication presenting module and an information presenting module, wherein

the indication presenting module is configured to identify the IMPUs with the equivalent behavior and to provide the information of the indicated IMPUs with the equivalent behavior to the information presenting module;

and

the information presenting module is configured to present the association information of the IMPUs with the equivalent behavior to the first requesting entity, according to the information of the indicated IMPUs with the equivalent behavior provided by the indication presenting module.

16. The system of claim 15, wherein the system further comprises a second requesting entity;

the first requesting identity is further configured to receive a subscription to notification of an event from the second requesting entity, and to present the association information of the IMPUs with the equivalent behavior to the second requesting entity by carrying the association information in the subscribed event packet, according to the subscription to notification of the event; and

the second requesting entity is configured to transmit the subscription to notification of the event to the first requesting identity, to receive the event packet from the first requesting identity, and to parse the association information of the IMPUs with the equivalent behavior from the received event packet.

17. The system of claim 16, wherein the second requesting entity is a UE, an AS or a P-CSCF.
