Abstract
In a wireless network, information regarding the power capabilities of a wireless device may be communicated to a wireless AP. The device itself may transmit such information, which may include a Max Idle Time period. The device may communicate the information within an association or re-association frame, for example as a parameter in a BSS Low Power Capability element. The AP may receive the information and set a keep-alive time period for the device based on the information. The AP may set the keep-alive time period to be equal to or greater than the Max Idle period. The AP may further communicate the keep-alive time period to the device, for example in an association or re-association response frame as a BSS Max Idle period element. In this way, the AP may apply different sets of parameters, such as different keep-alive time periods, to different classes of stations.
