Presentation Transcript

  1. IEEE 802.11 Wireless Interworking with External Networks (WIEN) Study Group Stephen McCann, Siemens Roke Manor stephen.mccann@roke.co.uk Stephen McCann, Siemens Roke Manor

  2. 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. Stephen McCann, Siemens Roke Manor

  3. 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 Stephen McCann, Siemens Roke Manor

  4. 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. Stephen McCann, Siemens Roke Manor

  5. 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. Stephen McCann, Siemens Roke Manor

  6. 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 Stephen McCann, Siemens Roke Manor

  7. 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) Stephen McCann, Siemens Roke Manor

  8. 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! Stephen McCann, Siemens Roke Manor

  9. 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) Stephen McCann, Siemens Roke Manor

  10. 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) Stephen McCann, Siemens Roke Manor

  11. WIEN SG Roadmap • July 2004 : Draft PAR & 5 Criteria • September 2004 : Motion to create TG, based on complete PAR & 5 Criteria • November 2004/January 2005 : TG Creation Stephen McCann, Siemens Roke Manor

  12. Additional IEEE 802.21 outputs, which would be useful to WIEN • Trigger models • Layer 2 interactions • Network Discovery issues • Authentication • IEEE 802.11 beacon enhancements Stephen McCann, Siemens Roke Manor
