Abstract

Under one aspect, a method of providing combinational services to a user endpoint includes providing a radio access network in communication with the user endpoint; providing a circuit-switched (CS) network in communication with the radio access network, the CS network comprising at least one mobile switching center (MSC) capable of providing a voice service to the user endpoint via the radio access network; providing an IP multimedia subsystem (IMS) core in communication with the radio access network, the IMS core comprising at least one call state control function (CSCF); providing one or more application servers (AS) in communication with the IMS core, the one or more AS capable of providing a corresponding one or more data services to the user endpoint via the CSCF and radio access network; providing a serving node (SN) in communication with the CS network and the IMS core; configuring logic in the MSC to send a first pre-defined message to the SN in response to a trigger detection point (TDP) that is triggered by the user endpoint requesting a voice service or a first entity requesting a voice service with the user endpoint; configuring logic in the CSCF to send a second pre-defined message to the SN in response to a service point trigger (SPT) that is triggered by the user endpoint requesting a data service or by a second entity requesting a data service with the user endpoint; and configuring logic in the SN to receive and respond to at least one of the first and second pre-defined messages by at least one of sending instructions to the MSC to provide a voice service to the user endpoint and sending instructions to the AS to provide a data service to the user endpoint.

Claims

1. A method of providing combinational services to a user endpoint, the method comprising:

providing a radio access network in communication with the user endpoint;

providing a circuit-switched (CS) network in communication with the radio access network, the CS network comprising at least one mobile switching center (MSC) capable of providing a voice service to the user endpoint via the radio access network;

providing an IP multimedia subsystem (IMS) core in communication with the radio access network, the IMS core comprising at least one call state control function (CSCF);

providing one or more application servers (AS) in communication with the IMS core, the one or more AS capable of providing a corresponding one or more data services to the user endpoint via the CSCF and radio access network;

providing a serving node (SN) in communication with the CS network and the IMS core;

configuring logic in the MSC to send a first pre-defined message to the SN in response to a trigger detection point (TDP) that is triggered by the user endpoint requesting a voice service or a first entity requesting a voice service with the user endpoint;

configuring logic in the CSCF to send a second pre-defined message to the SN in response to a service point trigger (SPT) that is triggered by the user endpoint requesting a data service or by a second entity requesting a data service with the user endpoint; and

configuring logic in the SN to receive and respond to at least one of the first and second pre-defined messages by at least one of sending instructions to the MSC to provide a voice service to the user endpoint and sending instructions to the AS to provide a data service to the user endpoint.

2. The method of claim 1, wherein the radio access network provides a connection between the user endpoint and only one of the CS network and IMS core at a given time.

3. The method of claim 1, further comprising registering the user endpoint to the IMS core.

4. The method of claim 3, wherein registering the user endpoint to the IMS core comprises obtaining at the CSCF information about the profile of the user endpoint.

5. The method of claim 1, wherein the profile of the user endpoint comprises the SPT.

6. The method of claim 1, wherein the SN determines whether the combinational service is authorized before responding to at least one of the first and second pre-specified messages.

7. The method of claim 1, wherein the first pre-defined message comprises a telephone number of the user endpoint and the nature of the voice service request.

8. The method of claim 1, wherein the second pre-defined message comprises an IP address of the user endpoint and the nature of the data service request.

9. A system for providing combinational services to a user endpoint, the system comprising:

a radio access network in communication with the user endpoint;

a circuit switched (CS) network in communication with the radio access network, the CS network comprising at least one mobile switching center (MSC) capable of providing a voice service to the user endpoint via the radio access network;

an IP multimedia subsystem (IMS) core in communication with the radio access network, the IMS core comprising at least one call state control function (CSCF);

an application server (AS) in communication with the IMS core, the AS capable of providing a data service to the user endpoint via the IMS core and the radio access network;

a serving node (SN) in communication with the CS network and the IMS core,

wherein the at least one MSC comprises logic configured to provide a first pre-determined message to the SN in response to a trigger detection point (TDP) that is triggered by voice service request by the user endpoint or by a first entity attempting to initiate a voice service with the user endpoint;

wherein the at least one CSCF comprises logic configured to provide a second pre-determined message to the SN in response to a service point trigger (SPT) that is triggered by a data service request by the user endpoint or by a second entity attempting to initiate a data service with the user endpoint; and

wherein the SN comprises logic configured to initiate a combinational service in response to receiving at least one of the first and second pre-determined messages, wherein initiating a combinational service comprises at least one of providing instructions to the MSC to initiate a voice service to the user endpoint and providing instructions to the AS to initiate a data service to the user endpoint.

10. The system of claim 9, wherein the radio access network is capable of providing a connection between the user endpoint and only one of the CS network and IMS core at a given time.

11. The system of claim 9, wherein the first pre-specified message comprises a telephone number of the user endpoint and information about the voice service request.

12. The system of claim 9, wherein the second pre-specified message comprises an IP address of the user endpoint and information about the data service request.

13. The system of claim 9, wherein the user endpoint comprises a personal agent (PA), the PA comprising logic programmed to provide the combinational service to the user.

14. The system of claim 13, wherein the PA further comprises a combinational state machine.

15. The system of claim 13, wherein the PA further comprises logic configured to transmit a third pre-determined message to the SN regarding at least one of a combinational service the user attempts to invoke on the user endpoint and the network environment of the user endpoint.

16. The system of claim 9, wherein the IMS core communicates with the radio access network via a packet switched (PS) network.

17. The system of claim 9, wherein the data service comprises a multimedia object.

18. The system of claim 17, wherein the SN further comprises logic configured to instruct the UE to render the multimedia object.

19. The system of claim 9, wherein the IMS core further comprises home subscriber subsystem (HSS) in communication with the CSCF, wherein the HSS comprises a profile of the user endpoint, and wherein the HSS comprises logic configured to transmit the profile of the user endpoint to the CSCF.

20. The system of claim 19, wherein the profile of the user endpoint contains the SPT.
