2. doc.: IEEE 802.11-03/006r0 Submission January 2003 Stephen McCann, Siemens Roke ManorSlide 2 IEEE 802.11 & WIG Plenary Motion Approved in 2002Plenary 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.

3. doc.: IEEE 802.11-03/006r0 Submission January 2003 Stephen McCann, Siemens Roke ManorSlide 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.

4. doc.: IEEE 802.11-03/006r0 Submission January 2003 Stephen McCann, Siemens Roke ManorSlide 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

5. doc.: IEEE 802.11-03/006r0 Submission January 2003 Stephen McCann, Siemens Roke ManorSlide 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.

6. doc.: IEEE 802.11-03/006r0 Submission January 2003 Stephen McCann, Siemens Roke ManorSlide 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

7. doc.: IEEE 802.11-03/006r0 Submission January 2003 Stephen McCann, Siemens Roke ManorSlide 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.

8. doc.: IEEE 802.11-03/006r0 Submission January 2003 Stephen McCann, Siemens Roke ManorSlide 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.

9. doc.: IEEE 802.11-03/006r0 Submission January 2003 Stephen McCann, Siemens Roke ManorSlide 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)

16. doc.: IEEE 802.11-03/006r0 Submission January 2003 Stephen McCann, Siemens Roke ManorSlide 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

17. doc.: IEEE 802.11-03/006r0 Submission January 2003 Stephen McCann, Siemens Roke ManorSlide 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

18. doc.: IEEE 802.11-03/006r0 Submission January 2003 Stephen McCann, Siemens Roke ManorSlide 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.
