Abstract

Several methods are provided for communicating emergency call capability information between a station and an access point (AP) in a wireless local area network. The methods include advertising by the AP of its emergency call capabilities and announcing by the station of its emergency call capabilities. The AP can advertise its emergency call capabilities in a beacon frame, a probe response frame, a reassociation response frame, or a reauthentication response frame. The station can announce its emergency call capabilities in an association request frame, a reassociation request frame, an authentication request frame, or a reauthentication request frame.
