Abstract

The subject matter described herein relates to methods, systems, and computer program products for providing Internet protocol multimedia subsystem (IMS) services in response to advanced intelligent network (AIN) triggers. According to one aspect, a method for providing an IMS service in response to an AIN trigger is provided. The method includes detecting the firing of an AIN trigger concerning an IMS registered non-IMS device. An IMS service to be provided in response to the AIN trigger is identified. The IMS service is provided.

Claims

1. A method for providing an IP multimedia subsystem (IMS) service in response to an advanced intelligent network (AIN) trigger, the method comprising:

detecting firing of an AIN trigger concerning an IMS-registered non-IMS device;

identifying an IMS service to be provided in response to the AIN trigger; and

providing the IMS service.

2. The method of claim 1 wherein detecting firing of an AIN trigger comprises detecting firing of a call originating attempt trigger.

3. The method of claim 1 wherein detecting firing of an AIN trigger includes detecting a call terminating attempt trigger.

4. The method of claim 1 wherein the IMS registered non-IMS device comprises a black phone.

5. The method of claim 1 wherein the IMS registered non-IMS device comprises a 2G mobile phone.

6. The method of claim 1 wherein detecting firing of an AIN trigger includes receiving a transaction capabilities application part (TCAP) message indicating the firing of the AIN trigger.

7. The method claim 6 wherein identifying an IMS service to be provided in response to the AIN trigger includes extracting information from the TCAP message and formulating a corresponding session initiation protocol (SIP) message including the trigger information and communicating the SIP message to a serving call state control function where the non-IMS device is registered.

8. The method of claim 7 wherein identifying the IMS service includes querying a home subscriber server (HSS) function to identify the IMS service.

9. The method of claim 1 wherein providing the IMS service includes querying an IMS platform corresponding to the identified service type.

10. The method of claim 1 wherein providing an IMS service includes providing one of a prepaid and a call screening service.

11. A system for providing an IP multimedia subsystem (IMS) service in response to an advanced intelligent network (AIN) trigger, the system comprising:

an AIN/IMS inter-working function for detecting firing of an AIN trigger concerning an IMS-registered non-IMS device;

a serving call session control function (S-CSCF) for identifying an IMS service to be provided in response to the AIN trigger; and

an IMS platform for providing the identified service.

12. The system of claim 11 wherein the AIN trigger comprises a call originating attempt trigger.

13. The system of claim 11 wherein the AIN trigger comprises a call terminating attempt trigger.

14. The system of claim 11 wherein the IMS-registered non-IMS device comprises a black phone.

15. The system of claim 11 wherein the IMS-registered non-IMS device comprises a 2G mobile telephone.

16. The system of claim 11 wherein the AIN/IMS inter-working function is adapted to detect the firing of the AIN trigger by receiving a transaction capabilities application part (TCAP) message including information identifying the AIN trigger.

17. The system of claim 16 wherein the AIN/IMS inter-working function is adapted to extract information from the TCAP message and formulate a corresponding SIP message including the AIN trigger identifying information.

18. The system of claim 17 wherein the S-CSCF is adapted to receive the SIP message from the AIN/IMS inter-working function and to query a home subscriber server (HSS) in order to identify the IMS service to be provided in response to the firing of the AIN trigger.

19. The system of claim 11 wherein the S-CSCF is adapted to query the IMS platform in order to provide the identified IMS service.

20. The system of claim 11 where in the IMS platform comprises one of a prepaid platform and a call screening platform.

21. A computer program product comprising computer executable instructions embodied in a computer readable medium for performing steps comprising:

detecting firing of an advanced intelligent network (AIN) trigger concerning an IP multimedia subsystem (IMS)-registered non-IMS device;

identifying an IMS service to be provided in response to the AIN trigger; and

providing the IMS service.
