IEEE 802.11 WIEN Notice
• Within this joint session IEEE 802.11
WIEN is only meeting in an ad hoc
manner. All decisions are therefore non
binding and will need to re-ratified at the
next WIEN meeting, scheduled for
Thursday 15th July 2004 at 16:00.
Submission

Objective
• IEEE 802.11 WIEN SG is currently
drafting a PAR and 5 Criteria
• Need to clarify a clear separation in scope
for IEEE 802 ExCom

IEEE 802.11 Interworking
• WIEN is looking at specific interworking issues
which are IEEE 802.11 technology specific
• In other words, issues which require a change to
the existing IEEE 802.11 standards.

IEEE 802.21 / WIEN
realationship
• It is recognised that WIEN (or future TG) will take IEEE
802.11 specific output from IEEE 802.21 and then make
the amendments to IEEE 802.21 (e.g. mobility model
issues)
• Current ‘scope’ of WIEN is to address 3GPP scenarios 1,
2.
• Current ‘scope’ of IEEE 802.21 is to address 3GPP
scenarios 4, 5
• Does IEEE 802.21 feel that WIEN should also consider
scenario 3.

IEEE 802.21 / WIEN
realationship II
• How will liaisons to 3GPP SA be handled :
– Joint
– Liaisons addressing different scenario cases
• IEEE 802.11 liaison officers

Objective of the WIEN sessions
• Technical submissions to refine scope and way
forward
• Complete PAR and 5 Criteria documents
• Produce roadmap for Study Group/Task Group
• Address open issues list
• Produce Motions (SG extension, Liaisons etc)
Submission

Air Interface Issues
• AR identifier (Needs further work)
– Supports layer 3 mobility. IP address change or not
• MAC address anonymity (Possibly)
– Protecting terminal identity
• Network Detection and Selection (Yes)
– Mandate from TGr and possible request from IETF
• Beacon scalability (Yes)
– What information can you transmit and how
frequently. Higher data rates do not help!

Air Interface Issues II
• Universal Access Method/11i co-existence
(Yes)
– User registration
• User clear down (Possibly)
– Graceful removal of user session
• Keying Issues (Possibly)

Network – Network Issues
• Policy enforcement (Not Sure)
• Access control (Yes)
– User revocation (Talk to WNM)
• Simultaneous access (Not Sure)
• External QoS mapping (Yes)
• Admission control (Yes)
