Abstract

Mediation systems and methods for hybrid networks including an IMS network. A system and method mediates an IMS network having a serving call state control function (S-CSCF) for providing session control for user endpoint (UE) devices with an alternative network to create a hybrid network. A service and corresponding service request code are defined to utilize at least a subset of capabilities provided by said alternative network. The S-CSCF is provisioned to identify and receive an alternative network service request message from a UE, including providing a call model having at least one filter code to associate said alternative network service code with at least one application server (AS) dedicated to serving alternative network service requests, said AS being responsive to service point triggers (SPTs). The AS is in communication with and capable of controlling delivery of at least a subset of services provided by said alternative network. The alternative network is a wireless broadcast network, such as a DVB-H network or a forward link only (FLO) network. The IMS network and S-CSCF and ASs are provisioned to provide two-way transport for interactive services for said hybrid network. The call model for alternative network services is constructed as a dynamic call model.

Claims

1. A system for mediating an IMS network having a serving call state control function (S-CSCF) for providing session control for user endpoint (UE) devices with an alternative network to create a hybrid network, said system comprising:

logic to define a service and corresponding service request code to utilize at least a subset of capabilities provided by said alternative network;

logic to provision the S-CSCF to identify and receive an alternative network service request message from a UE, said logic to provision including logic to provide a call model having at least one filter code to associate said alternative network service code with at least one application server (AS) dedicated to serving alternative network service requests, said AS being responsive to service point triggers (SPTs);

wherein said AS being in communication with and capable of controlling delivery of at least a subset of services provided by said alternative network.

2. The system of claim 1 wherein said alternative network is a wireless broadcast network.

3. The system of claim 2 wherein said wireless broadcast network is a DVB-H network.

4. The system of claim 2 wherein said wireless broadcast network is a forward link only (FLO) network.

5. The system of claim 1 wherein the IMS network and S-CSCF and ASs are provisioned to provide two-way transport for interactive services for said hybrid network.

6. The system of claim 1 wherein the call model for alternative network services is constructed as a dynamic call model.

7. The system of claim 1 wherein said AS utilizes proxy logic to communicate with the alternative network.

8. The system of claim 1 wherein said AS is located within said alternative network.

9. A method of mediating an IMS network having a serving call state control function (S-CSCF) for providing session control for user endpoint (UE) devices with an alternative network to create a hybrid network, said method comprising:

defining a service and corresponding service request code to utilize at least a subset of capabilities provided by said alternative network;

provisioning the S-CSCF to identify and receive an alternative network service request message from a UE, including providing a call model having at least one filter code to associate said alternative network service code with at least one application server (AS) dedicated to serving alternative network service requests, said AS being responsive to service point triggers (SPTs);

wherein said AS being in communication with and capable of controlling delivery of at least a subset of services provided by said alternative network.

10. The method of claim 9 wherein said alternative network is a wireless broadcast network.

11. The method of claim 10 wherein said wireless broadcast network is a DVB-H network.

12. The method of claim 10 wherein said wireless broadcast network is a forward link only (FLO) network.

13. The method of claim 9 wherein the IMS network and S-CSCF and ASs are provisioned to provide two-way transport for interactive services for said hybrid network.

14. The method of claim 9 wherein the call model for alternative network services is constructed as a dynamic call model.
