Presentation Transcript

  1. WNG – WIG update • IEEE 802.11 & WIG • What is this about ? • Intended Outputs (802.11 and WIG) • Why bother ? • WIG scope • How to do this work ? • WIG Roadmap • Draft PAR discussion Stephen McCann, Siemens Roke Manor

  2. IEEE 802.11 & WIG • Plenary Motion Approved in 2002 • Move that the WNG Standing Committee requests the 802.11 WG to accept the invitation from ETSI-BRAN and MMAC to participate in the “WLAN – 3G and other Public Access networks “interworking” (WIG) project. Stephen McCann, Siemens Roke Manor

  3. What is this about ? • To establish a joint-effort between 802.11 and ETSI BRAN/MMAC HSWA for the interworking of WLANs to 3G Cellular systems. • 802.11 should be represented by its own interworking group. Stephen McCann, Siemens Roke Manor

  4. Previous work • At engineering level, TGi already has similar approach to external authentication (EAPoL) to that of other WLAN standards (e.g. Hiperlan & HiSWAN) • Previous interworking activities done by ETSI BRAN and MMAC HSWA have similar approach to that of 802.1x Stephen McCann, Siemens Roke Manor

  5. 802.11 Intended Output ? • Necessity to align interworking work from TGe, TGi, WNG and 802.1 • Procedural requirement to establish some kind of interworking group within 802.11 to address these issues. Stephen McCann, Siemens Roke Manor

  6. WIG Intended Output ? • WIG Baseline Document • Common text, which will then be passed based to recognised WLAN standards bodies (ETSI, IEEE & MMAC) for their regulatory approval. • WIG cannot NOT approve final output Stephen McCann, Siemens Roke Manor

  7. Why bother ? • To create a world wide standard for WLAN interworking with Cellular and Public Access networks. • To encourage the proliferation of world wide WLAN hotspots, regardless of local regulatory constraints. Stephen McCann, Siemens Roke Manor

  8. WIG Scope • To be an integral part in the production of a generically applicable interworking standard for WWAN and other public networks. The standard is to be applicable for IEEE 802.11 family, MMAC HiSWAN family and ETSI HIPERLAN/2 • To be the point of resolution for ETSI, IEEE and MMAC on issues related to interworking with WWAN and other public networks. • To be the single point of contact for the above mentioned WLAN standards on questions related to interworking with WWAN and other public networks. Stephen McCann, Siemens Roke Manor

  9. How to do this work ? • Through WLAN Interworking Group (WIG) meetings • 3 times a year, co-hosted at IEEE 802.11, ETSI BRAN & MMAC HSWA meetings • Interim discussions at other meetings in between, to progress technical aspects (e.g. IEEE 802.11 Interworking group) Stephen McCann, Siemens Roke Manor

  10. Suggestion for Work Plan • Agreement on WIG Working Method and Workplan (Phased approach) • MMAC HSWA/ETSI BRAN Provides a first Input to R1 • IEEE 802.11 Interworking group to comment and decide on which issues that is agreeable or not • Iterations • Consensus for Release 1 • Ask for Approval for Release 1 • Timeline for Release 2 Stephen McCann, Siemens Roke Manor

  11. Roadmap • 08-13 September WIG#1 • 01-04 October BRAN#30 • 18. October – 06. December • 10. December – WIG#2 • 4-5th February WIG#2 • Following plenary meetings at each Std. Org. • 24th – 27th June WIG#3 (ETSI) Agreement on WIG Working Method and Workplan (Phased approach) MMAC/ETSI produces a layout for mutual standard with the suggested content of R1 (close to realisation today) IEEE to comment and decide on which issues that is agreeable or not Iterations Consensus for Release 1 Ask for Approval for Release 1 Timeline for Release 2 Stephen McCann, Siemens Roke Manor

  12. IEEE 802.11 PAR • No specific group in IEEE802.11 dedicated to interworking issues • Is WNG official representation in WIG ? • Many external activities in this area, WIG, 3GPP, GSMA, WiFi Alliance all addressing interworking issues. • Bits of interworking done in WNG, TGi, TGe, 802.1 (802.1x and 802.1aa) Stephen McCann, Siemens Roke Manor

  13. PAR output document • IEEE 802.11 approved document, containing WIG text for US regulatory requirements. Stephen McCann, Siemens Roke Manor

  14. WIG Next Steps • WIG #2 information • 4-5th February 2003, ARIB HQ, Tokyo, Japan • Technical contributions • WIG Baseline document update • Conformance with 802.1x/802.1aa issues • Conformance with 3GPP SA2 issues • Editorial matters Stephen McCann, Siemens Roke Manor

  15. PAR Discussion • Regarding the PAR • Is it a standard or recommended practice ? • Sponsors and names ok ? • Time line ok ? Stephen McCann, Siemens Roke Manor

  16. 5 line PAR Scope • The scope of the project is to enhance the 802.11 standard and amendments, through the generation of a standard to add interworking capability to both cellular and external IP based networks including the Internet. This project will conform with similar proposal specified by both Japanese (MMAC) and European (ETSI) standardization bodies Stephen McCann, Siemens Roke Manor

  17. 5 line PAR purpose • To generate two output documents to enhance the 802.11 standard and amendments : • Cellular and external IP network interworking requirements • Cellular and external IP network interworking reference architecture description • These outputs will define and specify the addition of specific interfaces to deal with interworking security, accounting and resource allocation between an 802.11 system and the aforementioned external networks Stephen McCann, Siemens Roke Manor

  18. PAR extra notes • The scope of this project is to develop a standard for the interworking of 802.11 with cellular and external IP networks. 802.11 have decided to participate within the Wireless Interworking Group which aims to produce a Generic Baseline Document for the interworking of all WLANs with cellular and external IP networks. It is therefore necessary for 802.11 to create a standard which specifies the requirements and interfaces between 802.11 and the WIG output document. • The intended WIG baseline document can not be implanted with the current amendments to 802.11 (e.g. 802.11i). This new standard works on the necessary new interfaces which will enable this to occur. Stephen McCann, Siemens Roke Manor
