Background
How to discover ESS services when your not connected
11u
Defined several features that enable a better relationship between the STA and the network behind the AP
Network Discovery (ANQP messages transported over GAS)
QoS Mapping (11e <-> network)
Multiple service provider subscriptions
Emergency services
11ai
Defining a solution to provide Fast link Set Up
Looking at optimisations of message exchanges (e.g. GAS & ANQP)
Enables efficient information transfer prior to association (e.g. IP address assignment)

Background
Current market needs
Enhanced user experience
Network service discovery pre-association
Use case: does this network support:
A 3D color printer?
Low resolution, free, sports highlights video?
Can the network support rich information queries
Smart server

Proposal
IEEE should evolve; improving the user experience is a valid goal.
Extend the 11u discovery mechanisms even further into the ESS
Nothing in IEEE PAR to prevent this
“Purpose: The purpose of this standard is to provide wireless connectivity for fixed, portable, and moving stations within a local area. “
Nothing in IEEE 802 rules to prevent this
What sort of thing am I looking for?
A new study group, perhaps “Discovery of ESS services”
Further extension of MAC frames
11u+ (??)
Some TGai aspects may help

More detail
Extend 11u network discovery mechanisms (e.g. GAS and ANQP) to enable discovery of information within the ESS:
Operates in a pre-associated and associated state
Information beyond the hotspot and local servers
Request/Response mechanism
STA in a pre-associated state
Richer request/response version of ANQP (not necessarily ANQP)
Provides a simple container to carry higher layer protocols (e.g. uPnP, Bonjour)
Other items (wish list)
Possibly provide response data integrity with signed requests
Extend neighbor report for APs in different regulatory classes
Possibly encapsulate a 3GPP protocol
Emergency services

Summary
Extend 11u network discovery mechanisms (e.g. GAS and ANQP) to enable transport for service discovery within the infrastructure (DS):
Operates in a pre-associated and associated state
Information beyond the hotspot and local servers
Request/Response mechanism
STA in a pre-associated state
Richer request/response version of ANQP (not necessarily called ANQP)
Provides a simple container to carry higher layer protocols (e.g. uPnP, Bonjour)
Other items to consider
Provide response data integrity with signed requests

Straw Poll: Should IEEE consider the creation of a study group to further discuss the topic of “discovery of ESS services”?
Result: Yes 53; No 1; Need more information: 30; Abstain/Don’t care 4
Motion: Request the WG to request approval by IEEE 802 LMSC to form an Study Group to consider the discovery of services within the access network with the intent of creating a PAR and five criteria.
Moved:  Stephen McCann (RIM)
Result: Yes: 32; No 12; Abstain 40; -- Motion fails
Conversation with No voters
Confusion about “P2P service discovery presentation” and this “discovery of ESS services”
This proposal does not include any P2P aspects and now considers the discovery of services within the IEEE network.
