METHOD, DEVICE AND SYSTEM FOR SETTING MAXIMUM STANDBY DURATION OF WIRELESS LOCAL AREA NETWORK STATION

摘要

A method, a device and a system for configuring maximum standby time of wireless local area network station are disclosed. The method includes the following steps that: an access point (AP) receives an association request or a re-association request sent from a wireless local area network station (STA); the AP judges whether or not the STA supports an extended values of a standard maximum idle period according to a preset flag in the association request or the re-association request received, wherein the standard maximum idle period is the maximum idle period defined in the 802.11v; if the STA fails to support the extended values, the AP configures the maximum idle period of the STA within the standard maximum idle period; and if the STA supports the extended values, the AP configures the maximum idle period of the STA within the standard maximum idle period or the extended values of the standard maximum idle period according to an instruction from an upper layer. The present invention enables an STA needing to stand by for a long time within associated with an AP for a longer time, thus preventing the STA from frequently sending a Keep-alive frame to the AP and consequentially saving the power consumption of the STA and prolonging the service life of the battery of the STA.
