March 2002 doc. : IEEE 802. 11 02/242 r 0 Content • • Intention Reason for and status of co-operation Scope and purpose of Standardisation in 3 GIWG Areas for possible co-operation – – Reference arch. Authentication System requirements Accounting Submission 2 Thomas Haslestad, Telenor

March 2002 doc. : IEEE 802. 11 02/242 r 0 INTENTION of Liaison • Inform on the recent activities within 3 GIWG • Highlight areas within which we can co-operate Submission 3 Thomas Haslestad, Telenor

March 2002 doc. : IEEE 802. 11 02/242 r 0 Reasons for co-operation • Unified Solution for 3 GPP – Common WLAN interface for their ongoing work on WLAN-3 G interworking – Interested parties in 3 GPP: SA 1, SA 2, SA 3, and T 2, T 3 • Unified Positioning towards IETF – Common set of requirements • Co-operation at lower layers – Increased commonality in implementation and impact on the market, for example roaming, interoperability • WLAN Public Access Interworking Global Solution Submission 4 Thomas Haslestad, Telenor

March 2002 doc. : IEEE 802. 11 02/242 r 0 Scope and Purpose of Standardisation within 3 GIWG Provisioning of a HIPERLAN/2 and Hi. SWANa interworking standard that is generically applicable to different 3 G interworking networks and other types of public access networks. • Present: Release 1 – To provide a secure authentication scheme through the network to be interworked – To provide basic functionality for charging and accounting • Future stage: Release 2 – To provide support for functionality such as service integration, mobility and Qo. S differentiation support Submission 6 Thomas Haslestad, Telenor

March 2002 doc. : IEEE 802. 11 02/242 r 0 Authentication • To achieve a single common view towards 3 GPP: – BRAN and HSWA believes that the mechanisms for remote authentication concerning the inter-working between WLAN and SPN needs to be common. – IEEE 802. 11 view on this is very much appreciated • Current working Assumption within 3 GIWG: – GAT (Generic Authentication Transport mechanism) – EAP based authentication scheme carried by GAT (EAPOH) Submission 10 Thomas Haslestad, Telenor

March 2002 doc. : IEEE 802. 11 02/242 r 0 Other • Accounting – Mechanisms are considered within the 3 GIWG work – Would very much value your opinion on the applicability of this work with respect to IEEE 802. 11 • Requirements – A set of system level requirements are identified in ETSI TR 101 957 ver. 1. 1. 1 – These are currently being mapped onto W. 2 Submission 11 Thomas Haslestad, Telenor
