Abstract
A wireless station (STA) of a wireless network operates to estimate intervals at which to transmit keep-alive messages to an access point (AP) with which the STA is associated. The STA receives a de-authentication frame from the AP. The de-authentication frame indicates that the AP has disassociated the STA due to inactivity. The STA determines a keep-alive interval based on one or more de-authenticated messages, including the de-authentication frame. The STA transmits keep-alive messages according to the determined keep-alive interval.
