Systems and methods for a wireless device wake-up process including power-save and non-power-save modes
First Claim
1. A method comprising:
- entering a wake-up detection mode at a wireless device for a pre-determined time period;
receiving a wake-up packet addressed to the wireless device, wherein the wake-up packet is configured to cause the wireless device to initiate a switch from operating in a power-save mode to operating in a non-power save mode;
performing a wake-up process at the wireless device to operate in the non-power save mode in response to receiving the wake-up packet; and
exiting the wake-up detection mode if the wake-up process is performed or the predetermined time period is exceeded.

Abstract
A system and method for wireless waking computing devices over a computer network is provided. A signal is broadcast over the network that includes one or more device specific wake-up data sequences. Each device specific wake-up data sequence includes multiple iterations of the hardware address of the wireless network card associated with that device. While in a reduced power or “sleep mode”, the wireless network card monitors wireless channels for packets containing a wake-up data sequence. If a wake-up data sequence is received, the sequence is matched against the hardware address information for that network card. If a match is determined, the network card sends a signal to the computing device causing full system power to be restored. A signal is sent to the network confirming that the device has been successfully woken from the sleep mode.

1. A method comprising:
-
entering a wake-up detection mode at a wireless device for a pre-determined time period; receiving a wake-up packet addressed to the wireless device, wherein the wake-up packet is configured to cause the wireless device to initiate a switch from operating in a power-save mode to operating in a non-power save mode; performing a wake-up process at the wireless device to operate in the non-power save mode in response to receiving the wake-up packet; and exiting the wake-up detection mode if the wake-up process is performed or the predetermined time period is exceeded. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A computer comprising:
-
a controller configured to trigger a wake-up detection mode at a wireless device for a pre-determined time period; and a communication interface coupled to the controller and configured to receive a wake-up packet addressed to the wireless device, wherein the wake-up packet is configured to cause the wireless device to initiate a switch from operating in a power-save mode to operating in a non-power save power mode; wherein the controller is further configured to perform a wake-up process at the wireless device to operate in the non-power save mode in response to receiving the wake-up packet and to exit the wake-up detection mode if the wake-up process is performed or the predetermined time period is exceeded. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable medium having instructions stored thereon that, if executed by a computing device, cause the computing device to perform operations comprising:
-
entering a wake-up detection mode at a wireless device for a pre-determined time period; receiving a wake-up packet addressed to the wireless device, wherein the wake-up packet is configured to cause the wireless device to initiate a switch from operating in a power-save mode to operating in a non-power save mode; performing a wake-up process at the wireless device to operate in the non-power save mode in response to receiving the wake-up packet; and exiting the wake-up detection mode if the wake-up process is performed or the predetermined time period is exceeded. - View Dependent Claims (16, 17, 18, 19, 20)
