Objectives
Study Group Proposal
Overall goal should be to define a standards ‚story‘ of how hotspots can be constructed, in a consistent and interoperable manner.

QoS (TGe only provides QoS over the air)
Handoff (but not 802 handoff)
Policy
Network layer issue, IETF, but does it impact IEEE ?
Mobility
same again, IETF, but remember that Fast Roaming SG is looking at ESS roaming.

Requirements
What is required for a public access hotspot standard?
Are all the pieces of the Jigsaw known ?
Is there a generic interface model to external networks ?
Who cares ?

Standards/Test Plans
Technology and therefore interfaces must be defined by standardisation body.
External interfaces should be defined by same body which defined the technology where possible.
Test plans should be defined by industry.
If test plans start to re-define the interfaces to the technology, where is the line drawn between technology definition and testing?

Who cares
Who should standardise an IEEE public access solution.
Should this be left to 3GPP and/or 3GPP2
What happens if their solutions impact the MAC layer.
Are their solutions compatible with the output of TGe, TGf, TGi, TGk and TGn.

Way forward
IEEE requires some extra work in the DS to define external interworking
TGe, TGf, TGi and TGk have started to do this already with functional definitions
Accounting/Charging ?
Policy ?
Should assess WFA, GSMA, 3GPP & 3GPP2 requirements placed on IEEE

Study Group Scope
The scope of the study group is to consider whether there is a requirement to enhance the IEEE standard (and amendments), to add interworking capability to both cellular and external IP based networks.
The intention is to re-use the output of existing Task Groups to form a complete interworking solution, and to fill in any gaps.

Motion
That an IEEE Study Group be formed, to determine whether there is a requirement to enhance the IEEE standard (and amendments), to add interworking capability to both cellular and external IP based networks. If it is determined necessary, the study group will then create a PAR and 5Criteria for further work within a Task Group.
