Embodiment 1

[0036] see figure 1 as shown, figure 1 A flow chart of a method for querying user data through an Sh interface provided by an embodiment of the present invention is used for data query through an Sh interface between an application server and a home user server, including steps:

[0037] Step 11: After receiving the registration message of a certain PUI, the application server sends a request message for querying user data to the home user server;

[0038] Step 12: The home user server returns all PUIs and their corresponding user data in the implicit registration set to which the public user identity PUI belongs to the application server through a response message.

[0039] In the embodiment of the present invention, by modifying the data model of the Sh interface on the HSS, the AS can use a Sh-Pull message to query all the PUIs and their user data in the implicit registration set to which the specified PUI belongs.

[0040] The specific modification of the data model of t...

Embodiment 2

[0067] see Figure 6 As shown, compared with Embodiment 1, Embodiment 2 proposes another Sh interface data model. In the Sh interface data model of Embodiment 2, in addition to containing multiple Sh-IMS-Data data in Sh-Data, no Including other data, Sh-Data and Sh-IMS-Data data can be simplified into an equivalence relationship. image 3 0 or 1 CS user status data, 0 or 1 PS user status data, 0 or 1 PS location information data, 0 or 1 CS location information data, 0 or 1 serving call control entity belonging to Sh-data Name data, 0 or 1 IMS user status data are moved into the Sh-IMS-Data data model.

[0068] Sh-IMS-Data includes 0-1 PSI activation information, 0-1 initial filtering rules, 0-1 service level tracking information, 0-n storage data, 0-n dynamic activation service information DSAI, 0- 1 charging information and 0-1 address security constraint information.

[0069] In this embodiment, the Sh-Data data does not include IMSUserState data and S-CSCFName data. The...

Embodiment 3

[0073] see Figure 7 As shown, the embodiment of the present invention also provides a device for querying user data through the Sh interface, which is used for data query through the Sh interface between the application server and the home user server, including:

[0074]The sending request module 71, after receiving the registration message of a certain PUI, sends a request message for querying user data to the home user server;

[0075] The response module 72 returns all PUIs and their corresponding user data in the implicit registration set to which the public user identity PUI belongs to the application server through a response message.

[0076] Further, it also includes:

[0077] Setting unit 73, set the feature bit of the Supported Feature parameter in the request message, so that the application server supports group user data download and set the Data-Reference parameter and the value of the Identity-Set parameter of the request message, so that an implicit registra...

Abstract

The invention discloses a method and a device for querying user data through a Sh interface in a multimedia subsystem (IMS), which are used for querying data through the Sh interface between an application server and a home subscriber server. The method comprises steps that: the application server receives a registration message of a certain public user identity (PUI) and transmits a request message for querying the user data to the home subscriber server; and the home subscriber server returns all PUI in an implicit registration set to which the PUI belongs and the user data corresponding to all PUI to the application server through a response message. Compared with the prior art, the invention has the advantages that: query operation message number at the Sh interface is simplified and the query efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and a device for querying user data through a Sh interface. Background technique [0002] In order to meet the needs of multimedia communication, the 3GPP organization introduced the IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) on the basis of the original packet bearer network. IMS can not only provide users with traditional voice services, but also provide users with rich multimedia experience . The IMS includes a call control entity (CSCF, Call Session Control Function), a home subscriber server (HSS, Home Subscriber Server) and an application server (AS, Application Server). The CSCF includes S-CSCF (Serving-Call Session Control Function, serving CSCF), I-CSCF (Interrogating-Call Session Control Function, querying CSCF), and P-CSCF (Proxy-Call Session Control Function, proxy CSCF). The interface between AS and HSS is called Sh interface....
