Month 2002 doc.: IEEE 802.11-02/xxxr0 September 2003 Interworking Scope The scope of the project is to enhance the 802.11 standard and amendments, through the generation of a Recommended Practice (or Standard) to add interworking capability to both cellular and external IP based networks (including the Internet) Stephen McCann, Siemens Roke Manor John Doe, His Company

Objectives To generate documents to enhance the IEEE 802.11 standard Month 2002 doc.: IEEE 802.11-02/xxxr0 September 2003 Objectives To generate documents to enhance the IEEE 802.11 standard To provide recommended practice for BSS to external network interoperability. These outputs will define and specify the addition of specific interfaces to deal with interworking (e.g. security) Looks at how other TGs fit into an overall interworking solution Creates a better hotspot user experience.

Month 2002 doc.: IEEE 802.11-02/xxxr0 September 2003 Way forward IEEE 802.11 requires some extra work in the DS to define external interworking TGe, TGf, TGi and TGk have started to do this already with functional definitions Accounting/Charging ? Policy ? Should assess WFA, GSMA, 3GPP & 3GPP2 requirements placed on IEEE 802.11 Stephen McCann, Siemens Roke Manor John Doe, His Company

Month 2002 doc.: IEEE 802.11-02/xxxr0 September 2003 3GPP Can proposed 3GPP interworking model be achieved from current IEEE 802.11 standards ? Stephen McCann, Siemens Roke Manor John Doe, His Company

WiFi Alliance Public Access Month 2002 doc.: IEEE 802.11-02/xxxr0 September 2003 WiFi Alliance Public Access WiFi Alliance Public Access III : QoS (TGe provides QoS over the air) Handoff (Provided by 802 Handoff group) Policy (Network layer issue, but does it impact IEEE 802.11) Mobility (same again) Roaming (same again, some provided by TGi) enhanced association service Stephen McCann, Siemens Roke Manor John Doe, His Company

Roadmap Draft skeleton becomes a Recommended Practice (RP) Month 2002 doc.: IEEE 802.11-02/xxxr0 September 2003 Roadmap Draft skeleton becomes a Recommended Practice (RP) Incorporate the WLAN interworking requirements from 3GPP, 3GPP2, GSMA, WiFi Alliance and others Work towards technical solutions for the differences between the interworking models Stephen McCann, Siemens Roke Manor John Doe, His Company

Month 2002 doc.: IEEE 802.11-02/xxxr0 September 2003 Straw Poll That a motion be raised at the Albuquerque meeting stating that an IEEE 802.11 Study Group be formed, to develop an amendment/recommended practice to extend and modify IEEE 802.11 to interwork with external IP networks, including Cellular networks.
