Abstract

Systems and methods for providing dynamic call models for users in an IMS network. A system and method provisions dynamic call models within an IMS network having a serving call state control function (S-CSCF) for providing session control for user endpoint (UE) devices. At least one user endpoint device (UE) with agent logic, expresses dynamic context of the UE in a message and sends said dynamic context message to a S-CSCF, wherein said dynamic context includes at least a subset of devices that could be used as UEs or associated devices, network connections that terminate or emanate from said devices that could be used as UEs or associated devices, and capabilities of said devices that could be used as UEs or associated devices. S-CSCF logic receives said context message from the UE and constructs a dynamic call model in response thereto, said dynamic call model having filter codes to associate IMS service codes with application servers (ASs) in communication with the IMS network, said ASs being responsive to service point triggers (SPTs) and each AS having service logic to provide a service for a corresponding IMS service code.

Claims

1. A system for provisioning dynamic call models within an IMS network having a serving call state control function (S-CSCF) for providing session control for user endpoint (UE) devices, said system comprising:

at least one user endpoint device (UE) with agent logic to express dynamic context of the UE in a message and to send said dynamic context message to a S-CSCF, wherein said dynamic context includes at least a subset of devices that could be used as UEs or associated devices, network connections that terminate or emanate from said devices that could be used as UEs or associated devices, and capabilities of said devices that could be used as UEs or associated devices; and

S-CSCF logic to receive said context message from the UE and to construct a dynamic call model in response thereto, said dynamic call model having filter codes to associate IMS service codes with application servers (ASs) in communication with the IMS network, said ASs being responsive to service point triggers (SPTs) and each AS having service logic to provide a service for a corresponding IMS service code.

2. The system of claim 1 wherein the logic to construct a dynamic call model includes logic to consult and use specified service policies in constructing said dynamic call models.

3. The system of claim 2 wherein the specified service policies govern use of newly discovered devices and new network connections.

4. The system of claim 2 wherein the specified service policies are specified and implemented by a service provider to control which devices may be used for which type of services for specified conditions.

5. The system of claim 2 wherein the specified service policies are user-specified.

6. The system of claim 2 wherein the specified service policies are specified by a network administrator.

7. The system of claim 1 further including logic to receive the context message and logic to build a data structure to reflect the dynamic context for the UE.

8. The system of claim 7 wherein the logic to receive and to build is contained in the S-CSCF.

9. The system of claim 7 wherein the logic to build said data structure is contained in a dedicated AS that is invoked by the S-CSCF when the S-CSCF receives the context message.

10. The system of claim 1 wherein the UE includes logic to electronically sense the dynamic context.

11. The system of claim 10 wherein the UE includes Universal Plug and Play Devices (UPnP) logic to electronically sense at least a subset of components in the dynamic context of the UE.

12. The system of claim 10 wherein the UE includes Jini logic to electronically sense at least a subset of components in the dynamic context of the UE.

13. The system of claim 10 wherein the UE includes RFID logic to electronically sense at least a subset of components in the dynamic context of the UE.

14. The system of claim 10 wherein the UE includes Bluetooth logic to electronically sense at least a subset of components in the dynamic context of the UE.

15. The system of claim 10 wherein the electronic sensing logic operates continuously.

16. The system of claim 10 wherein the electronic sensing logic operates periodically or at specified times.

17. The system of claim 10 wherein the electronic sensing logic operates on demand.

18. The system of claim 1 wherein the dynamic context message from the UE is issued post registration of the UE.

19. The system of claim 1 wherein the logic to construct a dynamic call model builds a new call model to replace a prior call model for a user.

20. The system of claim 1 wherein the logic to construct a dynamic call model builds new filter codes and pushes said new filter codes on top of the prior call model for a user.

22. The method of claim 1 wherein, when constructing a dynamic call model, specified service policies are consulted and used to construct said dynamic call models.

23. The method of claim 22 wherein the specified service policies govern use of newly discovered devices and new network connections.

26. The method of claim 22 wherein the specified service policies are specified by a network administrator.

21. A method of provisioning dynamic call models within an IMS network having a serving call state control function (S-CSCF) for providing session control for user endpoint (UE) devices, said method comprising:
