Abstract

Methods and systems for powering-off a Bluetooth device from a linked device are provided. A device can transmit a Bluetooth signal to a linked device to instruct the linked device to power-off. In this manner, the user need only turn off one device manually which results in all linked devices being powered off. This process can be initiated by a user through a device directly linked with the device to be powered-off or through a device that is indirectly connected, through one or more Bluetooth networks, with the device to be powered-off. This process can also be automatically initiated by a device when a set of predetermined conditions exist. Once instructed to do so, a device can initiate a predetermined power-off process which can involve terminating any ongoing functions and turning off various subsystems. In accordance with the present invention, a user can initiate a power-off of all the devices on a Bluetooth network through a single device.

Claims

1. An electronic device, comprising:

a Bluetooth transceiver; and

a processor configured to;

automatically initiate a power-off process of the electronic device if a battery level in the electronic device goes below a threshold; and

transmit a signal, in response to the initiating, to a second electronic device according to a Bluetooth communications protocol via the Bluetooth transceiver, wherein the signal includes an instruction to cause the second electronic device to initiate a power-off process of the second electronic device.

2. The electronic device of claim 1, wherein the power-off process of the second electronic device comprises transmitting a signal to a third electronic device, wherein the signal to the third electronic device contains an instruction to cause the third electronic device to initiate a power-off process of the third electronic device.

3. The electronic device of claim 1, wherein the transmitting the signal to the second electronic device comprises transmitting the signal via an ad hoc Bluetooth network.

4. The electronic device of claim 1, wherein the electronic device is a master device and the second electronic device is a slave device.

5. The electronic device of claim 1, wherein the electronic device is a cellular telephone and the second electronic device is a headset.

6. An electronic device, comprising:

a Bluetooth transceiver; and

a processor configured to;

configure a first power-off process for the electronic device;

initiate the first power-off process for the electronic device after the configuring;

transmit signals, after the initiating, to one or more second electronic devices according to a Bluetooth communications protocol via the Bluetooth transceiver, wherein the signals include instructions to cause the one or more second electronic devices to initiate respective second power-off processes.

7. The electronic device of claim 6, wherein the configuring comprises selecting the one or more second electronic devices.

8. The electronic device of claim 6, wherein the initiating the first power-off process is in response to a battery level of the electronic device falling below a threshold.

9. The electronic device of claim 6, further comprising a power button, wherein the initiating the first power-off process is in response to receiving input via the power button.

10. The electronic device of claim 6, wherein the processor is further configured to receive a signal from a third electronic device according to a Bluetooth communications protocol via the Bluetooth transceiver, wherein the initiating the first power-off process is in response to the receiving the signal from the third electronic device.

11. The electronic device of claim 10, wherein the processor is further configured to transmit a signal to the third electronic device according to a Bluetooth communications protocol via the Bluetooth transceiver, before the receiving the signal from the third electronic device, wherein the transmitted signal comprises a notification of a battery level of the electronic device falling below a threshold.

12. The electronic device of claim 10, wherein one of the electronic device or the third electronic device is a cellular telephone and the other of the electronic device or the third electronic device is a laptop computer.

13. The electronic device of claim 6, wherein the electronic device is a cellular telephone and the second electronic device is a headset.

14. The electronic device of claim 6, wherein at least one of the respective second power-off processes comprises transmitting a signal to a third electronic device, wherein the signal to the third electronic device includes an instruction to cause the third electronic device to initiate a third power-off process.

15. The electronic device of claim 6, wherein the transmitting signals to the one or more second electronic devices comprises transmitting at least one of the signals via an ad hoc Bluetooth network.

16. An electronic device, comprising:

a Bluetooth transceiver;

a user interface; and

a processor configured to;

receive an instruction via the user interface to switch the electronic device into an airplane mode; and

transmit, in response to the receiving the instruction, a signal to a second electronic device according to a Bluetooth communications protocol via the Bluetooth transceiver, wherein the signal includes an instruction to cause the second electronic device to initiate a power-off process.

17. The electronic device of claim 16, wherein the processor is further configured to switch the electronic device into the airplane mode in response to the receiving the instruction.

18. The electronic device of claim 16, wherein the power-off process of the second electronic device comprises transmitting a signal to a third electronic device, wherein the signal to the third electronic device includes an instruction to cause the third electronic device to initiate a power-off process of the third electronic device.

19. The electronic device of claim 16, wherein the transmitting the signal to the second electronic device comprises transmitting the signal via an ad hoc Bluetooth network.

20. The electronic device of claim 16, wherein the electronic device is a cellular telephone and the second electronic device is a headset.
