  2. Abstract Agenda and introductory slides for teleconference with 3GPP SA2 on 30th May 2007 Stephen McCann, NSN

  3. Introduction • Roll Call • Please note the following items: • IEEE Patent Policy - http://standards.ieee.org/board/pat/pat-slideset.ppt • Affiliation FAQ - http://standards.ieee.org/faqs/affiliationFAQ.html • ]Anti-Trust FAQ - http://standards.ieee.org/resources/antitrust-guidelines.pdf • Ethics - http://www.ieee.org/portal/cms_docs/about/CoE_poster.pdf • Status and main interest of IEEE 802.11 work related to 3GPP SA2 • Status and main interest of 3GPP SA2 related to IEEE 802.11 • Network selection and discovery • Use of SSID and other associated identifiers Stephen McCann, NSN

  4. Interworking Scope • Selection of a suitable IEEE 802.11 AN by consulting the SSPN • Selection of SSPN with its corresponding IEEE 802.11 AN. • Support for many SSPNs per BSS • Emergency service provisioning at the IEEE 802.11 network level • QoS map distribution • Interface services between AP and the SSPN Stephen McCann, NSN

  5. 802.11 Interworking Architecture Stephen McCann, NSN

  6. Interworking Interface • The Interworking interface allows the non-AP STA to transparently access the services provisioned in the SSPN via the currently associated BSS. • However, certain interworking services also allow the non-AP STA to access services in networks other than the SSPN. • How AP enforces this is outside the scope of Interworking Services. Note that Interworking Services are not supported in an IBSS Logical service interfaces. Stephen McCann, NSN

  7. Emergency Services • Support for emergency services when the user is accessing their services via WLAN • Service Capability Advertisement • Admission control • Unauthenticated network access using public user credentials on a dedicated emergency services SSID. For example, should there be a common set of credentials and identities? Stephen McCann, NSN

  8. Information Service (IS) • Scope differences between IEEE 802.11u and IEEE 802.21 • Architecture and signalling protocols beyond the WLAN access point (PDG/IMS/VCC in the case of 3GPP and optional use of the IEEE 802.21 Media Independent Handover Information Server (IS) in the case of IEEE 802) • Architecture and signalling protocols beyond the WLAN access point (PDG/IMS/VCC in the case of 3GPP and optional use of the IEEE 802.21 Media Independent Handover Information Server (IS) in the case of IEEE 802) • Other service availability and integrity issues eg protection against Distributed Denial of Service attacks Stephen McCann, NSN

  9. Authentication and Roaming Issues • 3GPP’s potential use of the new information provided by an IEEE 802.11u capable network to the AAA server in the mobile network for I-WLAN. • 3GPP’s potential use of the new control features provided by the IEEE 802.11u capable network from the AAA server in the mobile network for I-WLAN, for example QoS mapping between networks. Stephen McCann, NSN

  10. Generic Advertising Service (GAS) • The purpose of GAS functionality is to enable the non-AP STA to identify the availability and information related to desired network services, e.g. information about available SSPs and/or SSPNs, located in the DS. • The requirement for this functionality was originally identified by deployment issues associated with public access hotspots where it is currently impossible for users to determine whether they will be able to access network services based solely on information currently advertised by the network. • There is a need for non-AP STAs in “state-1” to query for information on network services provided by SSPNs beyond an AP.
