Re-use of ANQP
ANQP currently uses the Query List element to request network information from the Access Network Information Server
The Query List just uses single integer Info IDs as a search query.
For Service Discovery need something more powerful
Create a new ANQP query type called “Service Request”.
Allows an identifier to be included in the request.
AP needs to re-route this new Service Request ANQP-element and forward it to the Service Information Server (or the proxy)
Backward compatible with ANQP and does not effect other external programs like WFA Hotspot 2.0
