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
Objectives • To generate documents to enhance the IEEE 802.11 standard • To provide recommend practice for access point to external network interoperability. • These outputs will define and specify the addition of specific interfaces to deal with interworking (e.g. security) • Creates a better hotspot user experience. Stephen McCann, Siemens Roke Manor
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 ? • Must address W-ISP, 3GPP & 3GPP2 specific requirements placed on IEEE 802.11 Stephen McCann, Siemens Roke Manor
3GPP • Can proposed 3GPP interworking model can be achieved from current IEEE 802.11 standards ? Stephen McCann, Siemens Roke Manor
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 AP) • Mobility (same again) • Roaming (same again, some provided by TGi, some MAC layer ?, operator relationship, NAD • Enhanced Association Support (NAD) Stephen McCann, Siemens Roke Manor
Roadmap • Draft skeleton becomes a Recommended Practice (RP) • Incorporate the WLAN interworking requirements from 3GPP, 3GPP2, WiFi Alliance and others • Work towards technical solutions for the differences between the interworking models Stephen McCann, Siemens Roke Manor
Straw Poll • Request that an IEEE 802.11 Study Group be formed, at the Albuquerque meeting, to develop an amendment/recommended practice to extend and modify IEEE 802.11 to interwork with external IP networks, including Cellular networks. Stephen McCann, Siemens Roke Manor
