Abstract
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.
