o The chair requested approval by unanimous consent
o There was no objection from the task group, so the minutes are approved

o However, there are no minutes to approve as the joint meeting was an official TGv meeting.
· No official business was transacted on the scheduled teleconferences, so no minutes were taken.
Discussion of meeting objectives
· The group agreed to try to circulate another draft in a letter ballot.
· The editor noted that draft 2.01 is on the server as of 5:09 pm. Draft 2.01 incorporates all technical comment resolutions.
Document: 11-08/0326r7, Editorial Comment Resolution, Necati Canpolat
· The technical editor noted that two editorial comments require discussion
· CID 766 is labelled editorial, and is really a technical comment. After discussion, the group reclassified the comment as technical and made it part of the same group as CID 768.
· CID 751 was rejected, and reasons were entered into the comment spreadsheet.
Presentation: 11-08/0534r0, Proposal for dot11InterworkingServiceEnabled, Dave Stephenson
· Matthew Gast: On page 7, the new MIB attribute defined on page 7 is a misspelling: "dot11InterworkingServiceEnableded". I believe that it should be "dot11InterworkingServiceEnabled"
o Dave Stephenson: That is correct. The corrected text will be uploaded as 11-08/0534r1.
Motion (5:34 pm): "Move that IEEE 802.11u approves document 11-08-0534-01-lb122-MIB-Implemented-and-Enabled.doc and requests the technical editor to incorporate it into the IEEE 802.11u draft document."
· Discussion on the motion
o Necati Canpolat: Do we need to include the CIDs addressed by this submission?
o Stephen McCann: We typically approve the document and then mark the CIDs as resolved. Would it be acceptable to list the CIDs in the document?
· Necati Canpolat proposed amending the motion with the CID. The motion was amended to the following form by unanimous consent.
Motion (revised) (5:35 pm): "Move that IEEE 802.11u approves document 11-08-0534-01-lb122-MIB-Implemented-and-Enabled.doc and requests the technical editor to incorporate it into the IEEE 802.11u draft document. Note: refers to CID 148"
· Discussion on the motion:
o Question: What is the difference between r0 and r1.
§ Answer: The fix of the typo identified by Matthew Gast.
· The motion was adopted by unanimous consent.
· Motion passes.
Hongseok Jeon was not available to present on the SME mobility manager, so this presentation will be deferred.
Comment Resolution
· The comment spreadsheet is 11-08/0326. The current revision is revision 8.
· Discussion of bucket 30 deferred.
· CID 38
o Resolution: Reject. There is only reason for the link to come up, so reason codes are not necessary. Conditions for the link to come up are described 21.3.1.2.
o Added to comment group 6.
· CID 43
o Dave Stephenson: This is a biographical reference, not a normative reference. Therefore, it is acceptable to reject the comment. However, do not mark this comment as completed until George Bumiller returns to the task group.
· CID 48
o Dave Stephenson: This was the subject of a rejected presentation.
· CID 56
o Dave Stephenson: These are mSSID comments which are resolved by the potential adoption of draft 2.01.
· CID 59
o Necati Canpolat: This is an mSSID-related comment.
o Temporary resolution: This comment is tentatively rejected by the proposed mSSID resolution, and it is placed in the mSSID category.
· Revised spreadsheet to be saved as 11-08/0326r9.

Call to order
Meeting called to order on Monday, May 12, 2008 by Stephen McCann at 7:37 pm Eastern Daylight Time (EDT).
Presentation: 11-08/0595r0, Re-direct URL, Dave Stephenson
· Stephen McCann: There needs to be a length for the Redirect URL so that the receiver can parse the fields.
o Dave Stephenson: That is correct.
· Gabor Bajko: The Native GAS query is to find out whether the network is chargeable or not. How does this help do that?
o Dave Stephenson: If the network is chargeable, there are some URLs that will go through the AP even though the network is chargeable. By putting this into the native GAS query, the client can get the URL directly. The machine can autonomously fetch the URL and present it immediately.
· Gabor Bajko: This saves only one HTTP round-trip, so it does not dramatically improve the performance.
o Dave Stephenson: If the web authentication back end is selective, some HTTP Gets will go through and some won't.
· Gabor Bajko: The URL returned here is free to the user. Why is that useful?
o Necati Canpolat: You need to have the web page displayed so you get all the information.
· Mike Montemurro: Is this proposal targeted at non-browser devices? This is a good idea because it gives a URL to devices without a good browser service, and helps them to get on the network.
· Matthew Gast: Is this really solving a problem? URLs that don't get redirects are meant to be free. There is no need to challenge the user.
· Gabor Bajko: No matter what URL you type in, you get redirected to the same page. This does not add any value.
o Mike Montemurro: This problem would be easy to solve if there were only way to do this. There are 3-4 methods that do this, and not all rely on HTTP 3xx redirects.
o Dave Stephenson: Not all URLs redirect.
o Gabor Bajko: Even if you configure the URL and get a browser, that request may still be redirected, e.g. for load balancing. There is complicated network architecture that may prevent this proposal from working.
· Necati Canpolat: There are two scenarios: (1) in the cluster case, you hijack the session when a browser is launched, and (2) instead of a locally configured session hijack, there is a predetermined central authentication URL.
o Gabor Bajko: This still only saves one round trip in the best case.
o Dave Stephenson: this gives you a simple way to get authenticated straight away.
· Mike Montemurro: In 3GPP, you need to connect to the network, make an HTTP request, get rejected and then move on to another network.
o Matthew Gast: You still need to connect to network & get an IP address once you see the network. Does this save steps?
o Mike Montemurro: You could match it against a profile to automatically log a user in.
· Stephen McCann: This proposal gives the user a URL before an IP address. Does this make sense?
· Gabor Bajko: This is not necessary because you end up at the landing page anyway. In 3GPP, you don't use a URI.
o Dave Stephenson: Then contention that "whatever you put in, you wind up on the landing page" is incorrect. Some sites will allow free access to a few sites, but charge for the majority of sites.
o Gabor Bajko: Credentials must be protected, not sent over a cleartext link.
o Mike Montemurro: Credentials are sent over HTTPS.
o Gabor Bajko: Using HTTPS requires an IP address. This proposal does not help with automation.
· Mike Montemurro: The real issue is that hotspots require layer 3 authentication, and you have to deal with it.
Motion (8:13 pm): "Move that IEEE 802.11u approves document 11-08-0595-00-000u-lb122-redirect-url.doc, with the addition of a 2 octet length field for the resource URL in Figure 7-95bk and requests the technical editor to incorporate it into the IEEE 802.11u draft document."
· Moved by Dave Stephenson, seconded by Mike Montemurro
· No debate on the motion.
· Vote: 4 for – 1 against – 3 abstentions.
· Motion passes (80%)

Straw poll (9:33 pm): "Do you think that having extended capability bits for QoS Mapping, EBR, and Interworking Enabled" is a good idea?"
· Vote: 6 yes – 0 no
