Need for Project (From PAR)
This amendment will provide mechanisms that assist in pre-association discovery of services by addressing the means to advertise their existence and enable delivery of information that describes them. This information about services is to be made available prior to association by stations operating on IEEE wireless networks.
There are existing higher layer service discovery/description approaches (e.g. UPnP, Bonjour) as well as mechanisms to deliver information in pre-association states (e.g. just as ANQP can be delivered over GAS).

Way Forward
What do we want to do?
Use Case/Requirements analysis
Call for proposed solutions (complete/partial)
Down selection criteria (if multiple proposals)
Simple Protocol (quick)
Communication plan with other Fora (e.g. Wi-Fi Alliance?)

Quick Option
TGaq develops simple MAC protocol
Meets low level requirements of use cases
Other Fora deal with higher layers (L2+)
Liaison to other fora of our use cases

GAS
GAS designed to provide pre-association protocol
Request/Response mechanism to network server
Asynchronous timing
Built in server side delay (comeback delay)
Timing can be altered to reduce amount of Request/Responses

8. ANQP Access Network Query Protocol

March 2013
ANQP
Access Network Query Protocol
Designed to fetch static access network data from AP
Request sends integer cook book value (e.g. 258)
Response returns data (e.g. Venue Name)
RLQP similar for TVWS registered location data
Other QPs can be easily added
New “ANQP” protocol to carry UPnP, Bonjour frames
Do we have to determine which frames would be required?
Adjust the timing/frequency of queries
