Abstract

A method and apparatus for performing wake-up control are provided, where the method is applied to an electronic device, and the method may include the steps of: detecting whether a predetermined wake-up action is input into the electronic device, wherein the predetermined wake-up action is a user action for wake-up control; and when it is detected that the predetermined wake-up action is input into the electronic device, sending a wake-up packet carrying predetermined wake-up information to allow an internal circuit of another electronic device to be woken up in response to detection of the predetermined wake-up information.

Claims

1. A method for performing wake-up control, the method being applied to an electronic device, the method comprising the steps of:

detecting whether a predetermined wake-up action is input into the electronic device, wherein the predetermined wake-up action is a user action for wake-up control; and

when it is detected that the predetermined wake-up action is input into the electronic device, sending a wake-up packet carrying predetermined wake-up information to allow an internal circuit of another electronic device to be woken up in response to detection of the predetermined wake-up information;

wherein a wake-up service circuit of the other electronic device receives the wake-up packet and detects whether the predetermined wake-up information exists in the wake-up packet; and

when it is detected that the predetermined wake-up information exists in the wake-up packet, the wake-up service circuit of the other electronic device controls the internal circuit of the other electronic device to resume from suspension.

2. The method of claim 1, further comprising:

detecting information received from the other electronic device; and

when the information received from the other electronic device indicates an inactive status of the other electronic device, starting detecting whether the predetermined wake-up action is input into the electronic device.

3. The method of claim 1, wherein the predetermined wake-up information comprises a company identification (ID).

4. The method of claim 3, wherein the predetermined wake-up information further comprises a sequence number;

and the sequence number is a variable corresponding to a number of times that the predetermined wake-up action is detected.

5. The method of claim 4, wherein the predetermined wake-up information further comprises a predetermined wake-up pattern.

6. The method of claim 1, wherein the wake-up packet is a Bluetooth Low Energy (BLE) advertising packet;

and the wake-up service circuit of the other electronic device scans for the wake-up packet.

7. The method of claim 1, wherein the wake-up packet is an extended inquiry response (EIR) packet;

and the wake-up service circuit of the other electronic device performs inquiry for discovering the electronic device.

8. An apparatus for performing wake-up control, the apparatus comprises at least one portion of an electronic device, the apparatus comprising:

a transmitter arranged to transmit information for the electronic device; and

a processing circuit, coupled to the transmitter, arranged to control operations of the electronic device, wherein the processing circuit detects whether a predetermined wake-up action is input into the electronic device, wherein the predetermined wake-up action is a user action for wake-up control, and when it is detected that the predetermined wake-up action is input into the electronic device, the processing circuit sends, by utilizing the transmitter, a wake-up packet carrying predetermined wake-up information to allow an internal circuit of another electronic device to be woken up in response to detection of the predetermined wake-up information;

wherein a wake-up service circuit of the other electronic device receives the wake-up packet and detects whether the predetermined wake-up information exists in the wake-up packet; and

when it is detected that the predetermined wake-up information exists in the wake-up packet, the wake-up service circuit of the other electronic device controls the internal circuit of the other electronic device to resume from suspension.

9. The apparatus of claim 8, wherein the processing circuit detects information received from the other electronic device;

and when the information received from the other electronic device indicates an inactive status of the other electronic device, the processing circuit starts detecting whether the predetermined wake-up action is input into the electronic device.

10. The apparatus of claim 8, wherein the predetermined wake-up information comprises a company identification (ID).

11. The apparatus of claim 10, wherein the predetermined wake-up information further comprises a sequence number;

and the sequence number is a variable corresponding to a number of times that the predetermined wake-up action is detected.

12. The apparatus of claim 11, wherein the predetermined wake-up information further comprises a predetermined wake-up pattern.

13. The apparatus of claim 8, wherein the wake-up packet is a Bluetooth Low Energy (BLE) advertising packet;

and the wake-up service circuit of the other electronic device scans for the wake-up packet.

14. The apparatus of claim 8, wherein the wake-up packet is an extended inquiry response (EIR) packet;

and the wake-up service circuit of the other electronic device performs inquiry for discovering the electronic device.

15. A method for performing wake-up control, the method being applied to an electronic device, the method comprising the steps of:

receiving a wake-up packet from another electronic device and detecting whether predetermined wake-up information exists in the wake-up packet; and

when it is detected that the predetermined wake-up information exists in the wake-up packet, controlling an internal circuit of the electronic device to resume from suspension;

wherein the other electronic device detects whether a predetermined wake-up action is input into the other electronic device, wherein the predetermined wake-up action is a user action for wake-up control; and

when it is detected that the predetermined wake-up action is input into the other electronic device, the other electronic device sends the wake-up packet carrying the predetermined wake-up information to allow the internal circuit of the electronic device to be woken up in response to detection of the predetermined wake-up information.

16. The method of claim 15, wherein the wake-up packet is a Bluetooth Low Energy (BLE) advertising packet;

and the method further comprises;

scanning for the wake-up packet.

17. The method of claim 15, wherein the wake-up packet is an extended inquiry response (EIR) packet;

and the method further comprises;

performing inquiry for discovering the other electronic device.

18. An apparatus for performing wake-up control, the apparatus comprises at least one portion of an electronic device, the apparatus comprising:

a receiver arranged to receive information for the electronic device; and

a wake-up service circuit, coupled to the receiver, arranged to provide the electronic device with a wake-up service, wherein the wake-up service circuit receives, by utilizing the receiver, a wake-up packet from another electronic device and detects whether predetermined wake-up information exists in the wake-up packet, and when it is detected that the predetermined wake-up information exists in the wake-up packet, the wake-up service circuit controls an internal circuit of the electronic device to resume from suspension;

wherein the other electronic device detects whether a predetermined wake-up action is input into the other electronic device, wherein the predetermined wake-up action is a user action for wake-up control; and

when it is detected that the predetermined wake-up action is input into the other electronic device, the other electronic device sends the wake-up packet carrying the predetermined wake-up information to allow the internal circuit of the electronic device to be woken up in response to detection of the predetermined wake-up information.

19. The apparatus of claim 18, wherein the wake-up packet is a Bluetooth Low Energy (BLE) advertising packet;

and the wake-up service circuit of the electronic device scans for the wake-up packet.

20. The apparatus of claim 18, wherein the wake-up packet is an extended inquiry response (EIR) packet;
