IEEE P802.11 - Wireless Interworking with External Networks (WIEN) Study Group - MEETING UPDATE:

Status of WIEN Study Group

Wireless Interworking with External Networks

May 2004

Motivation

Hotspot use is currently gaining interest not only with ISPs but also with Cellular operators. It will become an increasing larger issue in public communications and it is felt by many that interworking of hotspots to external networks must be addressed by the IEEE 802.11, even if the conclusion of an initial investigation is that further standardization is not actually required.

Initial May 2004 Meeting Objectives

• Identify technical requirements, such as those on the MAC layer
• Determine impacts on IEEE 802.11, for example
  • network selection: is anything additional required in the MAC to support network selection, such as operator advertisement, discovery of network capabilities before authentication etc
  • resource management: MAC layer interactions with end-to-end resource allocation protocols, and exchange of information between MAC and higher layers to support admission control, accounting, resource monitoring etc
• Determine relationship with external standardization bodies

Work to be done

• Creation of PAR and 5Criteria with the objective of producing an output document which defines how to interwork IEEE 802.11 equipment with external networks (Cellular, Enterprise, ISPs) and where the control of such a system lies
• Draft set of open issues (e.g. layer 2 and layer 3 impacts)
• To underpin specific requirements raised by external standardization bodies

List of current open issues to be addressed

• Air Interface
  • Access Router identifier – layer 3 mobility
  • MAC address anonymity
  • Network Detection Selection
  • Beacon scalability
  • Universal Access Method/IEEE 802.11i co-existence
  • Channel Management
  • User registration
  • User clear down
  
  
• Network-Network Interface
  • Policy enforcement
  • Access control
  • Simultaneous access
  • External QoS mapping
  • User access revocation
  • Admission control

July 2004 Goals

• Discussion to determine whether above items are in scope
• Technical submissions on above open issues
• creation of suitable text for PAR and 5 Criteria
• Further discussion on relationship with external standardization bodies
