Public Access Task Group
41
Public Access Task Group

• The same functional components can also support
  browser-based authentication (UAM)
• 1 The wireless station (STA) discovers an 802.11
  access point (AP) and initiates a connection
  request
• 2 The AP (or a network authenticator) responds
  with a request for the STA identity.
• 3 The AP forwards the STA identity as an
  authentication request message to the local
  authentication server/proxy (AAA-V).
• 4 The AAA-V examines the STA identity and decides
  that this is a roaming user. It forwards the
  authentication request on to the AAA server of
  the home provider of that user (AAA-H) (often,
  but not necessarily, via an INT) based on the
  realm name specified in the STA identity.
• 5 The AAA-H authenticates the user via an
  EAP-based challenge-response method that runs
  end-to-end between the AAA-H and the STA. A
  local user database is consulted by AAA-H to
  verify the username and credential provided by
  the STA. The result of the authentication and
  session key material are communicated back to the
  AAA-V, AP, and STA.
• 6 The AP configures link-layer session keys and
  signals that the STA has been successfully
  authenticated. Prior to this time, the AP blocks
  any attempt by the STA to obtain an address or
  access the Internet.
• 7 The AAA-V sends accounting messages to AAA-H
  and possibly to a billing and settlement
  intermediary as well. When the STA disconnects,
  an accounting stop message is sent as the last
  message for that session. The billing and
  settlement components process the accounting data
  and generate charging and billing records.
  Depending upon the processing requirements of the
  billing/settlement components, AAA-V may also
  save the accounting records to a log file and
  send them in batch mode to the billing/settlement
  provider. Note that a billing/settlement
  intermediary may but will not necessarily also
  act as an aggregator for authentication. These
  are independent functions.
• 8 Charging records are exchanged between business
  entities involved in this scenario, and
  settlement occurs.
• 9 The home provider adds charges to the user's
  bill for the public WLAN usage.

• The rationale for optional certification is that
  as only some applications need QoS functionality
• Also recommend to the WFA Board to include
  certification of product interoperability with
  802.11e optional mechanisms, specifically
  Automatic Power Save Delivery (APSD), Block
  Acknowledgement and etc

Voice over Wi-Fi

• About the MRD view of Marketing TG
• The Voice over Wi-Fi Marketing Task Group's
  overall objective was to complete this MRD to be
  used by a Technical Task Group to guide test plan
  development and by the Board of Directors to
  steer their Voice-related strategy discussions.
• Some points in MRD
• The call can be initiated using any of the
  following commonly used voice call protocols
• SIP, H323, Skype
• One voice call is set up with a 1Mb bandwidth
  stream of background traffic? for home network
• Twelve voice calls are set up with a 3 Mb
  bandwidth stream of background traffic ? for
  commercial voice
• Any codec can be used.
• compliant to the requirements of the underlying
  base Wi-Fi certification grant (i.e., 802.11a,
  802.11g, 802.11b, WPA, dual band).

47
Application Specific Device Task Group

• The definition of ASD
• ASDs are 802.11 devices ,e.g., clients or access
  points, that cannot be tested under a standard
  Alliance test plan because they do not comply to
  the standard test configuration and/or because
  they are designed to perform a specific
  application.
