Access Network Query Protocol (ANQP)
ANQP provides a range of information, such as IP address type and availability, roaming
partners accessible through a hotspot, and the Extensible Authentication Protocol (EAP)
method supported for authentication, for a query and response protocol. The ANQP
Information Elements (IEs) provide additional data that can be sent from an AP to the client
to identify the AP's network and service provider. If a client requests this information through
a GAS query, the hotspot AP sends the ANQP capability list in the GAS Initial Response
frame indicating support for the following IEs:
●
Venue Name
●
Domain Name
●
Network Authentication Type
●
Roaming Consortium List
●
Network Access Identifier Realm
●
3GPP Cellular Network Data
●
IP Address Availability
Hotspot 2.0 Query Protocol (H2QP)
The H2QP profiles provide a range of information on Hotspot 2.0 elements such as hotspot
protocol and port, operating-class, operator names, WAN status, and uplink and downlink
metrics.
Information Elements (IEs) and Management Frames
The Hotspot 2.0 configuration supports the following IEs:
●
Interworking IE—Provides information about the Interworking service capabilities such as
the Internet availability in a specific service provider network.
●
Advertisement Protocol IE—Provides information about the advertisement protocol that a
client can use for communication with the advertisement servers in a network.
●
Roaming Consortium IE—Provides information about the service provider network for
roaming clients, which can be used to authenticate with the AP.
The IEs are included in the following Management Frames when 802.11u is enabled:
●
Beacon Frame
●
Probe Request Frame
●
Probe Response frame
●
Association Request
●
Re-Association request
