Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.11. Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.11 Working Group.

2. doc.: IEEE 802.11-05/0730r0 Submission July 2005 Stefano M. Faccin, NokiaSlide 2 Abstract This document contains the IEEE 802.11 – 3GPP2 liaison report for July 2005.

3. doc.: IEEE 802.11-05/0730r0 Submission July 2005 Stefano M. Faccin, NokiaSlide 3 3GPP2 Overview (1) What is 3GPP2? –Third Generation Partnership Project 2 –collaborative project born in 1998 out of the ITU International Mobile Telecommunications (IMT-2000) initiative –comprises North American and Asian interests developing global specifications for ANSI/TIA/EIA-41 network evolution to 3G, and global specifications for the radio transmission technologies supported by ANSI/TIA/EIA-41 –3GPP2 is a collaborative effort between five officially recognized SDOs acting as Operational Partners: ARIB - Association of Radio Industries and Businesses (Japan) CCSA - China Communications Standards Association (China) TIA - Telecommunications Industry Association (North America) TTA - Telecommunications Technology Association (Korea) TTC - Telecommunications Technology Committee (Japan) –In addition, Market Representation Partners (MRPs) who offer market advice to 3GPP2 and bring a consensus view of market requirements (e.g., services, features and functionality) participate to 3GPP2: The CDMA Development Group (CDG) IPv6 Forum International 450 Association (IA 450)

Four Technical Specification Groups (TSGs): –TSG-A (Access Network Interfaces) –TSG-C (cdma2000 ® ) –TSG-S (Services and Systems Aspects) –TSG-X (Core Networks ) More information on http://www.3gpp2.org

Faccin, NokiaSlide 5 3GPP2 Activities related to IEEE 802.11 (1) TGS S: –Stage-1 Requirements (S.R0087-0) published August 04 –Four main scenarios supported: Scenario 1: Common billing & Customer Care Scenario 2: Common authentication & WLAN Direct IP Access –Focus on 802.1X authentication with EAP-TLS; EAP-AKA –Access to IP connectivity, not 3GPP2 services Scenario 3: WLAN 3GPP2 IP Access –Authentication/authorization/accounting based on 3GPP2 Home System –Access to the 3GPP2 Home System packet data services Scenario 4: Session Continuity –continuity of a packet data session while switching of network connection takes places between the available access systems (e.g. WLAN-3GPP2)

6. doc.: IEEE 802.11-05/0730r0 Submission July 2005 Stefano M. Faccin, NokiaSlide 6 3GPP2 Activities related to IEEE 802.11 (2) TGS X: –Stage-2/3 Specification Phase I (X.P0028-0) completed (3Q04). Not published yet. Supports scenarios 1 and 2 –Stage-2/3 Specification Phase II (X.P0028-A). Completion aimed to 4Q05. Planned to support scenarios 3 and 4 Assumptions on 802.11: –Specifications currently assume no modifications to 802.11 specifications –Threat WLAN Access Network as a black box outside 3GPP2 control
