Abstract
A method of awaking a communication device operating in a sleep mode for a wireless network interface card includes continuously sending a plurality of coupling packets to maintain coupling between the communication device and a remote communication device, receiving a wireless packet from the remote communication device, determining a packet type of the wireless packet according to a packet format corresponding to a wake-up packet, and controlling the communication device to leave the sleep mode when the wireless packet is determined to be the wake-up packet.
Claims16
A method of awaking a communication device operating in a sleep mode, comprising:
- continuously sending a remote communication device a plurality of coupling packets to maintain coupling between the communication device and the remote communication device;
- receiving a wireless packet from the remote communication device;
- determining whether the wireless packet is a wake-up packet;
- and
- controlling the communication device to leave the sleep mode when the wireless packet is determined to be the wake-up packet.
A wireless network interface card of a communication device in a sleep mode, comprising:
- a transceiver for transmitting wireless signals corresponding to a plurality of coupling packets and receiving a wireless signal corresponding to a wireless packet sent by a remote communication device;
- a packet reception unit coupled to the transceiver, for receiving the wireless packet;
- a determining unit coupled to the packet reception unit, for determining whether the wireless packet corresponds to a wake-up packet and generating a control signal when the wireless packet is determined to be a wake-up packet;
- and
- a wake-up unit coupled to the determining unit, for controlling the communication device to leave the sleep mode according to the control signal.
A method of awaking a communication device comprising a wireless network interface card, the communication device at least comprising one sleep mode and one non-sleep mode, the method comprising:
- in the sleep mode, continuously sending a plurality of coupling packets to a remote communication device by the wireless network interface card;
- receiving a wireless packet from the remote communication device;
- determining whether the wireless packet corresponds to a packet type of a wake-up packet;
- and
- controlling the communication device to leave the sleep mode when the wireless packet corresponds to the wake-up packet.
