Abstract

System and method for receiving a call in a wireless device. A notification message is received over a first radio access technology (RAT) that another wireless device wants to engage in the call. At least one other RAT is identified that can be utilized to connect the call. The at least one other RAT is selected to connect the call. A connection is initiated through utilization of the at least one other RAT.

Claims

1. A method for receiving a call in a wireless device, comprising:

receiving a notification message over a first radio access technology (RAT) that another wireless device wants to engage in the call;

identifying at least one other RAT that can be utilized to connect the call;

selecting the at least one other RAT to connect the call; and

initiating connection of the call through utilization of the at least one other RAT.

2. The method of claim 1, further comprising:

registering with a wide area paging network.

3. The method of claim 2, wherein the step of receiving the notification message comprises:

receiving a page over the wide area paging network.

4. The method of claim 1, wherein the step of receiving the notification message comprises:

receiving information that identifies the at least one other wireless RAT.

5. The method of claim 4, wherein the step of identifying comprises:

identifying the at least one other RAT from the notification message.

6. The method of claim 1, further comprising:

scanning for available RATs that can be used to connect the call.

7. The method of claim 1, wherein the step of receiving the notification message comprises:

receiving at least one of an identification of the at least one other RAT, a location of an access point for the at least one other RAT, caller identification (ID) information, a location of the wireless device, a cost function of completing the call, and a data type to be exchanged during the call.

8. The method of claim 7, further comprising:

selecting criteria to employ when selecting the at least one other RAT.

9. The method of claim 8, wherein the step of selecting the at least one other RAT comprises:

employing the criteria in conjunction with information contained in the notification message to choose the at least one other RAT.

10. The method of claim 1, wherein the step of receiving the notification message comprises:

receiving preference information, from an operator of the wireless communication network, which identifies a preferred RAT for completing the call.

11. The method of claim 1, wherein the step of selecting the at least one other RAT comprises selecting a wireless local area network.

12. The method of claim 1, wherein the step of initiating connection comprises:

sending a call completion request to an exchange server on a wireless communication network.

13. A method, comprising:

receiving a call connection request, from a first communication device, to engage in a call with a second communication device;

determining whether or not the second communication device is registered to receive calls;

generating a call notification if the second communication device is registered to receive calls; and

sending the call notification to the first communication device over a wireless communication network that is dedicated to providing call notifications.

14. The method of claim 13, wherein the step of sending the call notification comprises:

sending a page to the second communication device over a wide area paging network.

15. The method of claim 13, wherein the step of generating the call notification comprises:

including, in the call notification, at least one of an identification of at least one other wireless communication network that can be utilized to connect the call, a location of an access point for the at least one other wireless communication network, caller identification (ID) information, a location of the second communication device, a cost function of completing the call, and a data type to be exchanged during the call.

16. The method of claim 13, wherein the step of generating the call notification comprises:

providing preference information in the call notification, which indicates a preferred wireless communication network for the second communication device to utilize when completing the call.

17. The method of claim 16, further comprising:

determining the location of the second communication device; and

employing the location of the second communication device to identify the preferred wireless communication network.

18. The method of claim 17, wherein the step of employing the location comprises:

identifying a wireless local area network proximate to the second communication device.

19. The method of claim 16, further comprising:

notifying the preferred wireless communication network that the second communication device will attempt to associate with it to complete the call.

20. The method of claim 19, wherein the step of notifying comprises:

providing the wireless local area network with a MAC address and authentication information for the second communication device.
