Abstract

An Internet Protocol Multimedia Subsystem (IMS) device includes a memory configured to store a subscriber profile, where the subscriber profile includes at least one criterion relating to an event that occurs after a session request has been forwarded to a terminating party. The IMS device further includes a processor configured to invoke at least one application service for a session based on the at least one criterion in the subscriber profile.

Claims

1. A system comprising:

an Internet Protocol Multimedia Subsystem (IMS) device to;

analyze a portion of a response to a call request based on a trigger point included in a subscriber profile associated with an originating device,

the response being received from a terminating device,

the call request being sent by the originating device to the terminating device;

invoke, based on analyzing the portion of the response, an application service, receive, based on invoking the application service, a filter criterion, and suppress, based on the filter criterion, an unexecuted trigger point in the subscriber profile associated with the originating device.

2. The system of claim 1, where the IMS device is further to:

set, prior to receiving the response, the trigger point, where the trigger point includes at least one trigger relating to the analyzed portion of the response.

3. The system of claim 1, where the IMS device is further to:

receive, based on invoking the application service, a returned message from an application server, and

invoke, based on receiving the returned message, one or more additional services.

4. The system of claim 1, where the IMS device is further to:

receive another filter criterion, and

execute, based on receiving the other filter criterion, the suppressed unexecuted trigger point.

5. The system of claim 1, where the IMS device receives the filter criterion from an application server associated with the application service based on the application server executing the application service.

6. The system of claim 1, where the subscriber profile associated with the originating device includes a plurality of trigger points, where the plurality of trigger points includes the trigger point and the unexecuted trigger point, and where at least one of the plurality of trigger points relates to at least one of:

a type of the response, a presence or an absence of a known header field in the response, or a presence or an absence of an unknown header field in the response.

7. The system of claim 1, where the subscriber profile associated with the originating device includes a plurality of trigger points, where the plurality of trigger points includes the trigger point and the unexecuted trigger point, and where at least one of the plurality of trigger points relates to at least one of:

a content of a known header field in the response, a content of an unknown header field in the response, a content of a session description protocol field in the response, or a content of a message body of the response.

8. The system of claim 1, where the subscriber profile associated with the originating device includes a plurality of trigger points, where the plurality of trigger points includes the trigger point and the unexecuted trigger point, and where at least one of the plurality of trigger points relates to a timer-based event.

9. A method comprising:

receiving, at an Internet Protocol Multimedia Subsystem (IMS) device, a call request from an originating device;

forwarding, via the IMS device, the call request to a terminating device;

receiving, at the IMS device, a response message based on the call request, the response message being received from the terminating device and the response message being for the originating device;

receiving, prior to invoking one or more application services and from an application server, a filter criterion;

altering, based on the filter criterion, an execution of one or more unexecuted trigger points included in a subscriber profile associated with the originating device; and

invoking, via the IMS device, the one or more application services, specified in the subscriber profile associated with the originating device, based on altering the execution of the one or more unexecuted trigger points.

10. The method of claim 9, further comprising:

analyzing, based on a trigger point included in the subscriber profile that is associated with the originating device, a portion of the response message; and

where the one or more application services are invoked based on analyzing the portion of the response message.

11. The method of claim 10, further comprising:

arming, based on receiving the call request, an initial filter criterion;

setting, prior to receiving the response message and based on the initial filter criterion being armed, the trigger point, where the trigger point includes at least one trigger relating to a portion of the response message; and

where the one or more application services are invoked based on the at least one trigger.

12. The method of claim 9, further comprising:

receiving, at the IMS device, a returned message from an application server associated with one of the one or more application services; and

invoking, based on receiving the returned message, one or more additional application services.

13. The method of claim 9, further comprising:

suppressing, based on the subscriber profile associated with the originating device, the response message.

14. The method of claim 9, further comprising:

forwarding, based on the subscriber profile associated with the originating device, the response message to the originating device.

15. A non-transitory computer-readable medium storing instructions, the instructions comprising:

one or more instructions that, when executed by a processor of an Internet Protocol Multimedia Subsystem (IMS) device, cause the processor to;

receive a call request from an originating device;

forward the call request to a terminating device;

receive a response message based on the call request, the response message being received from the terminating device and being intended for the originating device;

receive, prior to invoking one or more application services and from an application server, a filter criterion;

alter, based on the filter criterion, an execution of one or more unexecuted trigger points included in a subscriber profile associated with the originating device; and

invoke the one or more application services, specified in the subscriber profile associated with the originating device, based on altering the execution of the one or more unexecuted trigger points.

16. The non-transitory computer-readable medium of claim 15, where the instructions further comprise:

one or more instructions to analyze, based on a trigger point included in the subscriber profile associated with the originating device, a portion of the response message; and

where the one or more application services are invoked based on analyzing the portion of the response message.

17. The non-transitory computer-readable medium of claim 16, where the instructions further comprise:

one or more instructions to arm, based on receiving the call request, an initial filter criterion;

one or more instructions to set, prior to receiving the response message and based on the initial filter criterion being armed, the trigger point, where the trigger point includes at least one trigger relating to a portion of the response message; and

where the one or more application services are invoked based on the at least one trigger.

18. The non-transitory computer-readable medium of claim 15, where the instructions further comprise:

one or more instructions to receive a returned message from an application server associated with one of the one or more application services; and

one or more instructions to invoke, based on receiving the returned message, one or more additional application services.

19. The non-transitory computer-readable medium of claim 15, where the instructions further comprise:

one or more instructions to suppress, based on the subscriber profile associated with the originating device, the response message.

20. The non-transitory computer-readable medium of claim 15, further comprising:

one or more instructions to forward, based on the subscriber profile associated with the originating device, the response message to the originating device.
