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 a W-IAP
to the client to identify the W-IAP'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:
l Venue Name
l Domain Name
l Network Authentication Type
l Roaming Consortium List
l Network Access Identifier Realm
l 3GPP Cellular Network Data
Hotspot 2.0 Query Protocol (H2QP)
The H2QPprofiles 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:
l Interworking IE—Provides information about the Interworking service capabilities such as the Internet availability
in a specific service provider network.
l Advertisement Protocol IE—Provides information about the advertisement protocol that a client can use for
communication with the advertisement servers in a network.
l 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:
l Beacon Frame
l Probe Request Frame
l Probe response frame
l Association Request
l Re-Association request
NAI Realm List
An NAI Realm profile identifies and describes a NAI realm to which the clients can connect. The NAI realm settings
on a W-IAP as an advertisement profile to determine the NAI realm elements that must be included as part of a GAS
Response frame.
Configuring Hotspot Profiles
To configure a hotspot profile, perform the following steps:
1. Create the required ANQP and H2QP advertisement profiles.
2. Create a hotspot profile.
