Power saving in Wi-Fi devices utilizing bluetooth
First Claim
1. A computer-implemented method in a station of a wireless network for power saving to connected access points utilizing Bluetooth, comprising the steps of:
- a Wi-Fi radio of the station transitioning to deep sleep mode from active mode while a Bluetooth radio of the station remains actively connected to an access point;
maintaining an active connection to an access point while in deep sleep mode, wherein the station maintains active state information in a non-volatile internal data structure;
responsive to receiving the data packets addressed to the station at the access point while the station is in deep sleep mode, receiving an indication of data packets addressed to the Wi-Fi radio, over a Bluetooth radio of the access point;
sending a notification of active mode from the station, responsive to the station transitioning the Wi-Fi radio from the deep sleep ode to the active mode; and
receiving one or more data packets from the access point to the Wi-Fi radio of the station.

Abstract
The present description provides methods, computer program products, and systems for saving power in Wi-Fi devices utilizing Bluetooth. A Wi-Fi radio transitions to deep sleep mode from active mode while a Bluetooth radio remains active. An active Wi-Fi connection to the access point can be maintained by the station while in deep sleep mode as needed to prevent being disassociated. Responsive to the indication of data packets waiting at the access point, sent over the Bluetooth radio, the Wi-Fi radio at the station can be transitioned from the deep sleep mode to the active mode. A notification of active mode is sent to the access point currently associated with the Wi-Fi radio so that packets can be forwarded.

10. A non-transitory computer-readable medium storing source code that, when executed, performs a method in a station of a wireless network for power saving to connected access points utilizing Bluetooth, the method comprising the steps of:
-
a Wi-Fi radio of the station transitioning transition to deep sleep mode from active mode while a Bluetooth radio of the station remains actively connected to an access point; maintaining an active connection to an access point while in deep sleep mode, wherein the station maintains active state information in a non-volatile internal data structure; responsive to receiving the data packets addressed to the station at the access point while the station is in deep sleep mode, receiving an indication of data packets addressed to the Wi-Fi radio, over a Bluetooth radio of the access point; sending a notification of active mode from the station, responsive to the station transitioning the Wi-Fi radio from the deep sleep ode to the active mode; and receiving one or more data packets from the access point to the Wi-Fi radio of the station.
