Abstract
A client device may receive, from a computing device, a message indicating that a session duration of a current session is nearly over. The client device may close the current session as soon as the client device is idle for more than a configurable interval. A new session may be started with the computing device by the client device.
Claims19
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.

A method comprising:
- receiving, by a client device from an access point in a network, an unsolicited specific action frame after initiation of a current session and as a session duration of a current session nears a timeout value and before a timeout expiration, the unsolicited specific action frame indicating a maximum session duration time, wherein the maximum session duration time is a hard time limit comprising the timeout value 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;
- closing, by the client device, a current session following receipt of the unsolicited specific action frame;
- rejoining the network, by the client device following the closing of the current session;
- and
- determining, when rejoining the network, based on the maximum session duration time, whether or not to start a new session.

A system comprising:
- a memory storage;
- and
- a processing unit coupled to the memory storage, wherein the processing unit is operative to:
- receive, from an access point, an unsolicited specific action frame after initiation of a current session and as a session duration of a current session nears a timeout value and before a timeout expiration, the message indicating that the session duration of the current session established between the access point and a client device is expiring in the future, wherein the session duration is a hard time limit comprising the timeout value 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;
- close 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
- start a new session with the access point by the client device following the closing of the current session, wherein starting the new session restarts the session duration.
