Abstract
A method at a wireless station for receiving an out-of-band wakeup trigger, the method including 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; 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 access point.
Claims23
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.
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.
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.
