1. An access point (AP) comprising:
- a processor configured to generate an emergency basic service set identity (BSSID) for an emergency call to an emergency call center, wherein the emergency BSSID is associated with an emergency call security credential;
a transmitter configured to transmit a plurality of BSSIDs, wherein at least one of the plurality of BSSIDs is the emergency BSSID; and
a receiver configured to receive an access request indicating the emergency BSSID from a station (STA);
wherein the processor is further configured to grant emergency call access to the STA based on the emergency call security credential.

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.

9. A method for use in an access point (AP), the method comprising:
-
transmitting a first frame that contains a first security credential for associating with a first type of network; transmitting a second frame that contains an emergency call security credential for associating with a second type of network; receiving, from a station (STA), an association message that includes the first security credential or the emergency call security credential; granting the STA access to the first type of network on a condition that the received association message includes the first security credential, and granting access to the second type of network on a condition that the received association message includes the emergency call security credential, wherein access to the second type of network is for an emergency call. - View Dependent Claims (10, 11, 12, 13)
