METHODS FOR SUPPORTING EMERGENCY CALLS ON A WIRELESS LOCAL AREA NETWORK

摘要

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 cal l capabilities and announcing by the station of its emergency call capabilitie s. 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.
