METHOD AND APPARATUS FOR UPDATING PRESENCE STATE OF A STATION IN A WIRELESS LOCAL AREA NETWORK (WLAN)

摘要

A method and apparatus for presence state determination at an access point of a station determines whether a station associated with the access point is responsive to the access point to indicate the station is“present”or“not present”. The access point informs a presence server when the station's presence state changes. The presence server does not therefore need to rely on presence handshaking between the presence server and the station.
