Generic Advertisement Service GAS Queries

Page 139 highlights

Parameter venue-type Description Range Specifies the venue type to be - advertised in the IEs from APs associated with this hotspot profile. The complete list of supported venue types is described in Venue Types on page 140 NOTE: This parameter only defines the venue type advertised in the IEs from hotspot APs. To define the venue type to be included in ANQP responses, use the hotspot anqp-venue-name-profile command. Default - Usage Guidelines Use this command to configure a hotspot profile. Hotspot 2.0 is a Wi-Fi Alliance specification based on the 802.11u protocol, which allows wireless clients to discover hotspots using management frames (such as beacon, association request and association response), connect to networks, and roam between networks without additional authentication. The Hotspot 2.0 provides the following services: l Network discovery and selection- Allows the clients to discover suitable and available networks by advertising the access network type, roaming consortium, and venue information through the management frames. For network discovery and selection, Generic Advertisement Service (GAS) and Access Network Query Protocol (ANQP) are used. l QOS Mapping- Provides a mapping between the network-layer QoS packet marking and over- the-air QoS frame marking based on user priority. When a hotspot is configured in a network: l The clients search for available hotspots using the beacon management frame. l When a hotspot is found, the client sends queries to obtain information about the type of network authentication and IP address, and IP address availability using the Generic Advertisement Service (GAS) action frames. l Based on the response of the advertisement Server (response to the GAS Action Frames), the relevant hotspot is selected and the client attempts to associate with it. l Based on the authentication mode used for mobility clients, the client authenticates to access the network. Generic Advertisement Service (GAS) Queries An Organization Identifier (OI) is a unique identifier assigned to a service provider when it registers with the IEEE registration authority. A W-IAP can include its service provider OI in beacons and probe responses to clients. If a client recognizes the OI, it will attempt to associate to the W-IAP using the security credentials corresponding to that service provider. If the client does not recognize the OI, that client can send a Generic Advertisement Service (GAS) query to the AP to request more information more about the network before associating.

Parameter
Description
Range
Default
venue-type <venue-type>
Specifies the venue type to be
advertised in the IEs from APs
associated with this hotspot
profile. The complete list of
supported venue types is
described in
Venue Types on
page 140
NOTE:
This parameter only
defines the venue type
advertised in the IEs from
hotspot APs. To define the venue
type to be included in ANQP
responses, use the
hotspot
anqp-venue-name-profile
<profile-name>
command.
Usage Guidelines
Use this command to configure a hotspot profile. Hotspot 2.0 is a Wi-Fi Alliance specification based on the
802.11u protocol, which allows wireless clients to discover hotspots using management frames (such as
beacon, association request and association response), connect to networks, and roam between networks
without additional authentication.
The Hotspot 2.0 provides the following services:
l
Network discovery and selection— Allows the clients to discover suitable and available networks by
advertising the access network type, roaming consortium, and venue information through the management
frames. For network discovery and selection, Generic Advertisement Service (GAS) and Access Network
Query Protocol (ANQP) are used.
l
QOS Mapping— Provides a mapping between the network-layer QoS packet marking and over- the-air QoS
frame marking based on user priority.
When a hotspot is configured in a network:
l
The clients search for available hotspots using the beacon management frame.
l
When a hotspot is found, the client sends queries to obtain information about the type of network
authentication and IP address, and IP address availability using the Generic Advertisement Service (GAS)
action frames.
l
Based on the response of the advertisement Server (response to the GAS Action Frames), the relevant
hotspot is selected and the client attempts to associate with it.
l
Based on the authentication mode used for mobility clients, the client authenticates to access the network.
Generic Advertisement Service (GAS) Queries
An Organization Identifier (OI) is a unique identifier assigned to a service provider when it registers with the
IEEE registration authority. A W-IAP can include its service provider OI in beacons and probe responses to
clients. If a client recognizes the OI, it will attempt to associate to the W-IAP using the security credentials
corresponding to that service provider.
If the client does
not
recognize the OI, that client can send a Generic Advertisement Service (GAS) query to the
AP to request more information more about the network before associating.
