July 2003 Interworking Update Stephen McCann, Siemens Roke Manor Stephen McCann, Siemens Roke Manor

2 WIG #3 WLAN Interworking Group
Month 2002 doc.: IEEE /xxxr0 July 2003 WIG #3 WLAN Interworking Group Co-operation between ETSI BRAN, IEEE and MMAC HSWA to define a common approach and interface, based on loose coupling model, using IP. Output document : r0-WNG-WIG Baseline Document_II.doc ETSI BRAN & MMAC HSWA in hibernation Stephen McCann, Siemens Roke Manor John Doe, His Company

3 Wireless Interworking
July 2003 Wireless Interworking HLR AAAH 3GPP MNO Roaming Broker Mobile Client AC AAAH 3GPP2 MNO Internet W-ISP Access Network Home ISP AAAH Stephen McCann, Siemens Roke Manor

4 Month 2002 doc.: IEEE /xxxr0 July 2003 Interworking : Scope The scope of the project is to enhance the 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

5 Month 2002 doc.: IEEE /xxxr0 July 2003 Objectives To generate two output documents to enhance the 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 system and the aforementioned external networks. Stephen McCann, Siemens Roke Manor John Doe, His Company

6 Month 2002 doc.: IEEE /xxxr0 July 2003 Way forward 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 Stephen McCann, Siemens Roke Manor John Doe, His Company

7 July 2003 existing bits ? Stephen McCann, Siemens Roke Manor

8 Draft Skeleton Outline
Month 2002 doc.: IEEE /xxxr0 July 2003 Draft Skeleton Outline Information submission : r1 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

9 Current Actions From 3GPP
Month 2002 doc.: IEEE /xxxr0 July 2003 Current Actions From 3GPP Can proposed 3GPP interworking model can be achieved from current standards ? Will be able to use Diameter ? What entity will produce charging records within the Access Network ? Will policy control be provided within the Access Network ? Stephen McCann, Siemens Roke Manor John Doe, His Company

10 Roadmap Encourage technical submissions for Singapore meeting
Month 2002 doc.: IEEE /xxxr0 July 2003 Roadmap Encourage technical submissions for Singapore meeting 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 Move to create a study group in Singapore Stephen McCann, Siemens Roke Manor John Doe, His Company
