1. A method comprising:
receiving, by a client device from an access point, an unsolicited specific action frame after initiation of a current session and as a session duration of the current session nears a timeout value and before a timeout expiration, the unsolicited specific action frame indicating that the session duration of the current session established between the access point and the client device is expiring in the future, wherein the session duration is a hard time limit comprising the timeout value manually defined for each session from each client device associated with the access point in a Pre-Shared Key (PSK)-based network, and wherein the unsolicited specific action frame comprises a session expiration warning and an amount of time until the session duration is expiring;
closing, by the client device, the current session as soon as the client device is idle for more than a configurable interval following receipt of the unsolicited specific action frame indicating that the session duration of the current session is expiring in the future; and
starting a new session with the access point by the client device following the closing of the current session.
