Abstract

A system and method provisions dynamic call models within a network having a serving node for providing session control for user endpoint (UE) devices. A user endpoint device (UE) with agent logic, expresses dynamic context of the UE in a message and sends said dynamic context message to a serving node. The dynamic context includes 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. The serving node logic receives said context message from the UE and constructs a dynamic call model in response. The dynamic call model having filter codes to associate service codes with application servers (ASs) in communication with the network, and each AS having service logic to provide a service.

Claims

1. A system for provisioning dynamic call models within a network having a serving node 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 dynamic context message and to send said dynamic context message to a serving node, wherein said dynamic context includes one or more other devices that are located in the vicinity of the UE and could be used as UEs or associated devices, network connections that terminate or emanate from at least one of said UE and said other devices that could be used as UEs or associated devices, and capabilities of said other devices that could be used as UEs or associated devices; and

serving node logic to receive said dynamic context message from the UE and to construct a dynamic call model in response thereto, said dynamic call model having filter codes to associate network service codes with application servers (ASs) in communication with the network, said ASs being responsive to service triggers and at least one AS having service logic for a corresponding network serving node to provide a service to the user, utilizing at least one of said other device expressed in the dynamic context message, said network connections that terminate or emanate from the other device expressed in the dynamic context message, and said capabilities of the other device expressed in the dynamic context message.

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 serving node.

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 serving node when the serving node 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.

24. The method of claim 22 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.

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 a network having a serving node function for providing session control for user endpoint (UE) devices, said method comprising:

receiving a dynamic context message from a UE, wherein the dynamic context message expresses a dynamic context of at least one user endpoint device (UE) in a message, wherein said dynamic context includes one or more other devices that that are located in the vicinity of the UE and could be used as UEs or associated devices, network connections that terminate or emanate from at least one of said UE and said other devices and could be used as UEs or associated devices, and capabilities of said other devices that could be used as UEs or associated devices; and

provisioning the serving node logic to construct dynamic call model in response to the receipt of the dynamic context message, said dynamic call model having service codes to associate service with application servers (ASs) in communication with the network, said ASs being responsive to service triggers and at least one AS having service logic for a corresponding service code to provide a service to the user, utilizing at least one of said other device expressed in the dynamic context message, said network connections that terminate or emanate from the other device expressed in the dynamic context message, and said capabilities of the other device expressed in the dynamic context message.
