Abstract

Methods of operating a short-range Radio Frequency (RF) device are provided. The methods may include transmitting identification information that identifies the short-range RF device and/or sensor information generated by a sensor associated with the short-range RF device, using a short-range RF communication protocol. The methods may include receiving a command, responsive to the identification information and/or the sensor information, from a server via a first device using the short-range RF communication protocol to control a second device associated with the short-range RF device. Related devices are also provided.

Claims

1. A method of operating a short-range Radio Frequency (RF) device, comprising:

transmitting identification information that identifies the short-range RF device, using a short-range RF communication protocol; and

receiving a command, responsive to the identification information, from a server via a first device using the short-range RF communication protocol to control a second device associated with the short-range RF device.

2. The method of claim 1, wherein transmitting the identification information comprises:

transmitting sensor information generated by a sensor associated with the short-range RF device and encrypted identification information that identifies the short-range RF device.

3. The method of claim 1, wherein transmitting the identification information comprises:

transmitting encrypted identification information that identifies the short-range RF device at least twice before receiving the command from the server.

4. The method of claim 1, wherein:

the first device comprises a first portable electronic device communicating with the short-range RF device using a first short-range RF communication link; and

transmitting the identification information comprises transmitting encrypted identification information that identifies the short-range RF device to a second portable electronic device using a second short-range RF communication link.

5. The method of claim 4, wherein:

at least one of the first and second short-range RF communication links with the short-range RF device is initiated and used independently of any user input at a respective one of the first and second portable electronic devices; and

receiving the command further comprises receiving the command via the second portable electronic device.

6. The method of claim 1, wherein transmitting the identification information comprises:

transmitting encrypted identification information that identifies the short-range RF device and an unencrypted indication to at least one device to directly forward the encrypted identification information to the server or another server without buffering the encrypted identification information in the at least one device.

7. The method of claim 1, wherein the identification information is destined for the server and/or another server.

8. The method of claim 7, wherein the command from the server comprises identification information that identifies the short-range RF device and a control command to be executed by the second device.

9. The method of claim 8, wherein the identification information received from the server comprises a plurality of identities of the short-range RF device.

10. The method of claim 8, wherein receiving the command from the server comprises:

receiving a command identifier associated with the command, the method the further comprising;

verifying, using the command identifier, that the command has not previously been received and/or executed since transmitting the identification information.

11. The method of claim 1, wherein transmitting the encrypted identification information comprises:

indiscriminately broadcasting the encrypted identification information, using the short-range RF communication protocol, such that at least one anonymous adjacent portable electronic device will receive the encrypted identification information.

12. A short-range Radio Frequency (RF) device, comprising:

a transmitter configured to transmit identification information that identifies the short-range RF device, using a short-range RF communication protocol; and

a receiver configured to receive a command, responsive to the identification information, from a server via a first device using the short-range RF communication protocol to control a second device associated with the short-range RF device.

13. The short-range RF device of claim 12, wherein the transmitter is configured to transmit sensor information generated by a sensor associated with the short-range RF device and encrypted identification information that identifies the short-range RF device.

14. The short-range RF device of claim 12, wherein the transmitter is configured to indiscriminately broadcast the identification information using the short-range RF communication protocol such that at least one anonymous adjacent portable electronic device will receive the identification information.

15. The short-range RF device of claim 12, wherein:

the first device comprises a first portable electronic device configured to communicate with the short-range RF device using a first short-range RF communication link; and

the transmitter is configured to transmit the identification information to a second portable electronic device configured to communicate with the short-range RF device using a second short-range RF communication link.

16. A method of operating a server in a wireless communications network, comprising:

receiving identification information that identifies a short-range Radio Frequency (RF) device, from a relaying electronic device; and

transmitting a command, responsive to the identification information and destined for the short-range RF device, to the relaying electronic device and/or another relaying electronic device to control a device associated with the short-range RF device.

17. The method of claim 16, wherein:

receiving the identification information comprises;

receiving sensor information generated by a sensor associated with the short-range RF device and encrypted identification information that identifies the short-range RF device.

18. The method of claim 16, wherein transmitting the command comprises:

transmitting the command to a plurality of relaying electronic devices.

19. The method of claim 16, further comprising:

determining that at least one relaying electronic device is likely to be near the short-range RF device, wherein transmitting the command comprises;

transmitting, via a cellular network, the command to the at least one relaying electronic device determined as likely to be near the short-range RF device.

20. The method of claim 19, wherein:

access to the cellular network is limited or unavailable adjacent the short-range RF device; and

the at least one relaying electronic device is configured to receive the command via the cellular network and to relay the command to the short-range RF device using a short-range RF communication protocol.
