Method and system for wakeup trigger by out-of-band communication
First Claim
1. A method at a wireless station for receiving an out-of-band wakeup trigger, the method comprising:
- receiving, at the wireless station, a message from an access point, the message providing an indication that the access point supports out-of-band signaling;
associating with the access point over a first radio technology;
establishing a connection with the access point using a second radio technology;
entering a sleep state for a radio using the first radio technology;
detecting other signals for the second radio technology to maintain a list of target access points;
upon a quality of the connection using the second radio technology falling below a threshold, waking up the radio for the first radio technology to associate with a target access point within the list of target access points; and
upon receiving a wakeup trigger over the connection using the second radio technology, waking up the radio for the first radio technology for communication with the target access point.

12. A wireless station configured for receiving an out-of-band wakeup trigger, the wireless station comprising:
-
a processor; and a communications subsystem, wherein the wireless station is configured to; receive a message from an access point, the message providing an indication that the access point supports out-of-band signaling; associate with the access point over a first radio technology; establish a connection with the access point using a second radio technology; enter a sleep state for a radio using the first radio technology; detect other signals for the second radio technology to maintain a list of target access points; upon a quality of the connection using the second radio technology falling below a threshold, wake up the radio for the first radio technology to associate with a target access point within the list of target access points; and upon receiving a wakeup trigger over the connection using the second radio technology, wake up the radio for the first radio technology for communication with the target access point. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A non-transitory computer readable medium for storing program instructions for receiving an out-of-band wakeup trigger, the program instructions, when executed by a processor of a wireless station, cause the wireless station to:
-
receive a message from an access point, the message providing an indication that the access point supports out-of-band signaling; associate with the access point over a first radio technology; establish a connection with the access point using a second radio technology; enter a sleep state for a radio using the first radio technology; detect other signals for the second radio technology to maintain a list of target access points; upon a quality of the connection using the second radio technology falling below a threshold, wake up the radio for the first radio technology to associate with a target access point within the list of target access points; and upon receiving a wakeup trigger over the connection using the second radio technology, wake up the radio for the first radio technology for communication with the target access point.
