摘要： Disclosed is a method for supporting an idle mode of a terminal in a wireless local area network (WLAN) system. In the method, a first request message for starting an idle mode is transmitted to a first access node to which the terminal is currently connected and a first response message with respect to the first request message is received from the first access node, and in this case, when the first response message includes acceptance information with respect to the start of the idle mode, the idle mode starts.

摘要： The present invention relates to a power saving in a wireless local area network including a plurality of access points providing at least one mobile station in each access point cell boundary with access service, the mobile station transits between an active mode and an idle mode. The power saving method includes grouping the access points into at least one paging group with a paging group boundary; determining if the a mobile station is in the idle mode in which the mobile station switches between an awake state and a doze state every predetermined time interval, or the active mode in which the mobile station is in the awake mode; and if the mobile station is in the idle mode enabling an idle handoff which occurs only when the mobile station crosses the paging group boundary. In the present invention, the handoff occurs when the mobile terminal crosses the paging group boundary but not the access point cell in the idle mode, resulting in reduction of power consumption.
