Abstract

A communication system alerts wireless communication interfaces of incoming calls. The communication system includes a service control point. The service control point receives a call set-up message for an incoming call. The service control point processes the call set-up message to identify a wireless communication interface. The service control point then generates an alert message indicating the incoming call and caller information from the call set-up message. The service control point transmits the alert message to the wireless communication interface. The service control point receives a response message wherein the response message indicates a destination communication device to receive the incoming call. The service control point processes the response message to generate and transmit a routing instruction that connects the incoming call to the destination communication device.

Claims

1. A method of operating a service control point, the method comprising:

receiving a call set-up message into the service control point for an incoming call;

processing the call set-up message to identify a first device where the first device is a wireless device;

generating an alert message indicating the incoming call and caller information from the call set-up message;

transmitting the alert message from the service control point to the first device;

receiving a response message into the service control point from the first device wherein the response message indicates a second device to receive the incoming call;

processing the response message to generate a routing instruction that connects the incoming call to the second device; and

transmitting the routing instruction from the service control point.

2. The method of claim 1 wherein the second device comprises a pager, a personal digital assistant, or a cellular phone.

3. The method of claim 1 wherein the call set-up message comprises a Transaction Capabilities Application Part query.

4. The method of claim 1 wherein the alert message comprises a called number, a dialed number, or a caller number.

5. The method of claim 1 further comprising determining whether the incoming call is to be intercepted for a called party.

6. The method of claim 1 further comprising generating a session for the incoming call with a session identifier.

7. A computer-readable medium having encoded thereon instructions that, when executed by a processor, direct the processor to:

receive a call set-up message for an incoming call, process the call set-up message to identify a first device where the first device is a wireless device, generate an alert message indicating the incoming call and caller information from the call set-up message, transmit the alert message to the first device, receive a response message from the first device wherein the response message indicates a second device to receive the incoming call, process the response message to generate a routing instruction that connects the incoming call to the second device, and transmit the routing instruction.

8. The computer-readable medium of claim 7 wherein the first device comprises a pager, a personal digital assistant, or a cellular phone.

9. The computer-readable medium of claim 7 wherein the call set-up message comprises a Transaction Capabilities Application Part query.

10. The computer-readable medium of claim 7 wherein the alert message comprises a called number, a dialed number, or a caller number.

11. The computer-readable medium of claim 7 wherein the instructions, when executed by the processor, direct the processor to determine whether the incoming call is to be intercepted for a called party.

12. The computer-readable medium of claim 7 wherein the instructions, when executed by the processor, direct the processor to generate a session for the incoming call with a session identifier.

13. A communication system comprising:

a service control point (SCP) comprising;

a processor configured to receive a call set-up message for an incoming call, process the call set-up message to identify a first device where the first device is a wireless device, generate an alert message indicating the incoming call and caller information from the call set-up message, transmit the alert message to an SCP interface, receive a response message from the first device wherein the response message indicates a second device to receive the incoming call, process the response message to generate a routing instruction that connects the incoming call to the second device, and transmit the routing instruction; and

the SCP interface connected to the processor and configured to transfer the call set-up message to the processor, transfer the alert message from the processor to the first device, and transfer the routing instruction from the processor.

14. The communication system of claim 13 wherein the first device comprises a pager, a personal digital assistant, or a cellular phone.

15. The communication system of claim 13 wherein the call set-up message comprises a Transaction Capabilities Application Part query.

16. The communication system of claim 13 wherein the alert message comprises a called number, a dialed number, or a caller number.

17. The communication system of claim 13 wherein the processor is configured to determine whether the incoming call is to be intercepted for a called party.

18. The communication system of claim 13 wherein the processor is configured to generate a session for the incoming call with a session identifier.

19. The communication system of claim 13 further comprising a switching system connected to the SCP and configured to process the routing instruction that connects the incoming call with the second device.
