Wireless communications gateway

1. A method for facilitating communications between monitoring and monitored devices, the method comprising the acts of:

establishing, by a mobile station, a voice communication link with a monitoring device via a wide area network;

receiving, by the mobile station, a request for a data communication link with a monitored device;

establishing, by the mobile station, the data communication link with the monitored device, the data communication link being a short-range wireless communication link; and

forwarding, by the mobile station, data between the monitoring and monitored devices;

wherein the monitoring and monitored devices communicate with each other via the mobile station,

wherein the mobile station acts as a gateway between the monitoring device and the monitored device, and

wherein data received from the monitored device is forwarded to the monitoring device via a wireless control channel.

2. The method of claim 1 , further comprising the act of:

establishing a data communication link between the mobile station and the monitoring device, wherein the data received from the monitored device is forwarded to the monitoring device via the data communication link.

3. The method of claim 1 , wherein data forwarded from the monitored device includes diagnostic data related to operation of the monitored device.

4. The method of claim 3 , wherein data forwarded from the monitoring device includes a request for the diagnostic data.

5. The method of claim 4 , wherein the request for diagnostic data includes an instruction for the monitored device to perform a diagnostic test.

6. The method of claim 1 , wherein the monitored device is a component of an appliance.

7. The method of claim 1 , wherein the monitored device is a component of a motor vehicle.

8. The method of claim 1 , wherein the short-range wireless communication link is a Bluetooth wireless communication link.

9. The method of claim 1 , wherein the short-range wireless communication link is a Wi-Fi communication link.

10. The method of claim 1 , further comprising the act of performing a payment validation process, wherein the monitored device is a payment terminal and the monitoring device is a payment authorization service provider.

11. A mobile station comprising:

a processor;

a wireless wide area network interface coupled to the processor; and

a short-range wireless communication interface coupled to the processor,

wherein the processor includes

logic for establishing a voice communication link with a monitoring device via the wide area network interface;

logic for receiving a request for a data communication link with a monitored device;

logic for establishing the data communication link with the monitored device, the data communication link being a short-range wireless communication link; and

logic for forwarding data between the monitoring and monitored devices;

wherein the monitoring and monitored devices communicate with each other via the mobile station,

wherein the mobile station acts as a gateway between the monitoring device and the monitored device, and

wherein data forwarded from the monitored devices towards the monitoring device is transmitted towards the monitoring device via a wireless control channel.

12. The mobile station of claim 11 , further comprising:

a memory,

wherein the processor is a microprocessor, and the logic is loaded into the processor from the memory.

13. The mobile station of claim 11 , wherein the processor is an application specific integrated circuit (ASIC) or field programmable gate array.

14. The mobile station of claim 11 , wherein the short-range wireless communication interface is a Bluetooth interface.

15. The mobile station of claim 11 , wherein the short-range wireless communication interface is a Wi-Fi interface.

16. The mobile station of claim 11 , wherein the wireless wide area network interface supports voice and data communications.

17. The mobile station of claim 11 , wherein the data forwarded between the monitoring and monitored devices includes a request for diagnostic information regarding the monitored device.

18. The mobile station of claim 11 , wherein the data forwarded between the monitoring and monitored devices includes a control program for the monitored device.

19. The mobile station of claim 11 , wherein the monitored device is a payment terminal, the monitoring device is a payment authorization service provider and the mobile station acts as a gateway for payment validation.
