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

Month 2002 doc.: IEEE 802.11-02/xxxr0 July 2003 Objectives To generate two output documents to enhance the 802.11 standard and amendments: i)  Cellular and external IP network interworking requirements ii) 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.

Month 2002 doc.: IEEE 802.11-02/xxxr0 July 2003 Way forward 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 ? Must address W-ISP, 3GPP & 3GPP2 specific requirements placed on 802.11 Stephen McCann, Siemens Roke Manor John Doe, His Company

Draft Skeleton Outline Month 2002 doc.: IEEE 802.11-02/xxxr0 July 2003 Draft Skeleton Outline Information submission : 11-03-459r1 Authentication (TGi) Authorization (TGi) Accouting (IPDR) QoS (TGe) Policy (DiffServ/COPS) Mobility (Macro : MIP, Micro : TGk, Handoff) Stephen McCann, Siemens Roke Manor John Doe, His Company

Current Actions From 3GPP Month 2002 doc.: IEEE 802.11-02/xxxr0 July 2003 Current Actions From 3GPP Can proposed 3GPP interworking model can be achieved from current 802.11 standards ? Will 802.11 be able to use Diameter ? What entity will produce charging records within the 802.11 Access Network ? Will policy control be provided within the 802.11 Access Network ?
