Abstract

A server and method are described herein that can influence the invoking of a service provided by an application server to a user-user equipment. The server includes a database that stores a service profile for the user-user equipment, where the service profile has a number of filter criteria wherein at least one includes: (1) a first trigger point and at least one first service point trigger that specifies one or more conditions which when satisfied will be downloaded to and checked by a remote control function before a service is invoked for the user-user equipment; and (2) a second trigger point and at least one second service point trigger that specifies one or more conditions which are checked against internally stored data associated with the user-user equipment and need to be satisfied before the service profile with the filter criteria including the first trigger point and the at least one first service point trigger is downloaded to and checked by the remote control function to invoke the service for the user-user equipment.

Claims

1. A server, comprising:

a database that stores a service profile for a user-user equipment, where the service profile has a number of filter criteria wherein at least one includes;

a first trigger point and at least one first service point trigger that specifies one or more conditions which when satisfied will be downloaded to and checked by a remote control function before a service is invoked for the user-user equipment; and

a second trigger point and at least one second service point trigger that specifies one or more conditions which are checked against internally stored data associated with the user-user equipment and need to be satisfied before the service profile with the filter criteria including the first trigger point and the at least one first service point trigger is downloaded to and then checked by the remote control function to invoke the service for the user-user equipment.

2. The server of claim 1, wherein said at least one first service point trigger further includes:

a request Uniform Resource Indicator (URI);

a Session Initiation Protocol (SIP) Method;

a Session Initiation Protocol (SIP) Header;

a Session Case;

or

a Session Description.

3. The server of claim 1, wherein said internally stored data is non-Session Initiation Protocol (SIP) related data including:

a Circuit Switch (CS) status of the user-user equipment;

an IP Connectivity Access Network (IP-CAN) accessed by the user-user equipment;

or

a type of Packet Switch (PS) network accessed by the user-user equipment.

4. The server of claim 1, wherein the at least one second service point trigger has a boolean expression in Conjunctive Normal Form, CNF, or in Disjunctive Normal Form, DNF, that specifies the one or more conditions which are to be checked against the internally stored data associated with the user-user equipment.

5. A method for enabling a server to influence an invoking of a service to a user-user equipment, said method comprising the steps of:

creating a service profile for the user-user equipment, where the service profile has a number of filter criteria wherein at least one includes;

a first trigger point and at least one first service point trigger that specifies one or more conditions which have to be satisfied before a remote control function can invoke the service for the user-user equipment; and

a second trigger point and at least one second service point trigger that specifies one or more conditions which will be checked against internally stored data that is associated with the user-user equipment;

pre-filtering the filter criteria by determining if there is a match between the one or more conditions in the at least one second service point trigger and the internally stored data that is associated with the user-user equipment;

if there is a match, then downloading the service profile with the filter criteria including the first trigger point and the at least one first service point trigger to the remote control function, wherein the remote control function then needs to confirm that the one or more conditions of the at least one first service point trigger are satisfied before invoking the service for the user-user equipment; and

if there is not a match, then preventing the download of the service profile with the filter criteria including the first trigger point and the at least one first service point trigger to the remote control function.

6. The method of claim 5, wherein said pre-filtering step is performed when the user-user equipment registers with the remote control function.

7. The method of claim 5, wherein said pre-filtering step is performed when another user-user equipment attempts to terminate a session with the user-user equipment.

8. The method of claim 5, wherein said pre-filtering step is performed after provisioning the service profile of the user-user equipment.

9. The method of claim 5, wherein said pre-filtering step is performed after a change in the internally stored data associated with the user-user equipment.

10. The method of claim 5, wherein said server is a Home Subscriber Server, HSS, which is used within a 3GPP network.

11. The method of claim 5, wherein the filter criteria is an Initial Filter Criteria, IFC, which is used within a 3GPP network.

12. The method of claim 5, wherein said remote control function is a Serving Call Session Control Function, S-CSCF, which is used within a 3GPP network.

13. The method of claim 5, wherein said at least one first service point triggers further includes:

a request Uniform Resource Indicator (URI);

a Session Initiation Protocol (SIP) Method;

a Session Initiation Protocol (SIP) Header;

a Session Case;

or

a Session Description.

14. The method of claim 5, wherein said internally stored data is non-Session Initiation Protocol (SIP) related data including:

a Circuit Switch (CS) status of the user-user equipment;

an IP Connectivity Access Network (IP-CAN) accessed by the user-user equipment;

or

a type of Packet Switch (PS) network accessed by the user-user equipment.

15. The method of claim 5, wherein the at least one second service point trigger has a boolean expression in Conjunctive Normal Form, CNF, or in Disjunctive Normal Form, DNF, that specifies the one or more conditions which are to be checked against the internally stored data associated with the user-user equipment.

16. A 3GPP network, comprising:

a Home Subscriber Server (HSS);

a Serving. Call Session Control Function (S-CSCF);

an IMS Application Server, wherein the HSS influences an invoking of an IMS service provided by said IMS Application Server to a user-user equipment by;

creating a service profile for the user-user equipment, where the service profile has a number of Initial Filter Criteria (IFC) wherein at least one includes;

a first trigger point and at least one first service point trigger that specifies one or more conditions which have to be satisfied before the CSCF invokes the IMS service for the user-user equipment; and

a second trigger point and at least one second service point trigger that specifies one or more conditions which will be checked against internally stored data that is associated with the user-user equipment;

pre-filtering the IFC by determining if there is a match between the one or more conditions in the at least one second service point trigger and the internally stored data that is associated with the user-user equipment;

if there is a match, then downloading the service profile with the IFC including the first trigger point and the at least one first service point trigger to the S-CSCF, wherein the S-CSCF then has to confirm that the one or more conditions of the at least one first service point trigger are satisfied before invoking the IMS Application Server to provide the IMS service for the user-user equipment; and

if there is not a match, then preventing the download of the service profile with the IFC including the first trigger point and the at least one first service point trigger to the S-CSCF.

17. The 3GPP network of claim 16, wherein said at least one first service point trigger further includes:

a request Uniform Resource Indicator (URI);

a Session Initiation Protocol (SIP) Method;

a Session Initiation Protocol (SIP) Header;

a Session Case;

or

a Session Description.

18. The 3GPP network of claim 16, wherein said internally stored data is non-Session Initiation Protocol (SIP) related data including:

a Circuit Switch (CS) status of the user-user equipment;

an IP Connectivity Access Network (IP-CAN) accessed by the user-user equipment;

or

a type of Packet Switch (PS) network accessed by the user-user equipment.

19. The 3GPP network of claim 16, wherein the at least one second service point trigger has a boolean expression in Conjunctive Normal Form, CNF, or in Disjunctive Normal Form, DNF, that specifies the one or more conditions which are to be checked against the internally stored data associated with the user-user equipment.
