Method for performing wake-up control with aid of wake-up packet, and associated apparatus

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 the predetermined wake-up information comprises a company identification (ID), and further comprises a sequence number and a predetermined wake-up pattern, and the sequence number is a variable corresponding to a number of times that the predetermined wake-up action is detected;
• wherein a wake-up service circuit of the other electronic device receives the wake-up packet, detects whether the predetermined wake-up information exists in the wake-up packet, and compares the predetermined wake-up information in the wake-up packet with predetermined wake-up information in the other electronic device;
• and
• when the predetermined wake-up pattern in the wake-up packet matches the predetermined wake-up information in the other electronic device, but the sequence number does not, the sequence number in the other electronic device will be set to the sequence number in the wake-up packet, and the wake-up service circuit of the other electronic device controls the internal circuit of the other electronic device to resume from suspension.

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, detecting whether predetermined wake-up information exists in the wake-up packet, and comparing the predetermined wake-up information in the wake-up packet with predetermined wake-up information in the electronic device, wherein the predetermined wake-up information comprises a company identification (ID), and further comprises a sequence number and a predetermined wake-up pattern;
• and
• when the predetermined wake-up pattern in the wake-up packet matches the predetermined wake-up information in the electronic device, but the sequence number does not, setting the sequence number in the electronic device to the sequence number in the wake-up packet, and 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 the sequence number is a variable corresponding to a number of times that the predetermined wake-up action is detected;
• 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.

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, detects whether predetermined wake-up information exists in the wake-up packet, and compares the predetermined wake-up information in the wake-up packet with redetermined wake-u information in the electronic device and when the predetermined wake-up pattern in the wake-up packet matches the predetermined wake-up information in the other electronic device, but the sequence number does not, the sequence number in the electronic device will be set to the sequence number in the wake-up packet, and, the wake-up service circuit controls an internal circuit of the electronic device to resume from suspension, wherein the predetermined wake-up information comprises a company identification (ID), and further comprises a sequence number and a predetermined wake-up pattern;
• 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 the sequence number is a variable corresponding to a number of times that the predetermined wake-up action is detected;
• 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.
