Information Structure

• Requirements
• Extensible
• Include other emerging networks
• New information elements
• Compatible
• With other similar information formats (MIBs,
  802.11k , CCX, IKE, etc.)
• Easy to Parse and well understood
• Use Compiler/Parser etc. tools already available
  and in use
• Existing Information formats
• ASN.1
• XML
• TLV
• Variant based
• Use ASN.1 for extensibility, compatibility and
  ease of use

3
Information Elements

• Type of wireless network
• 802.x, zG, etc.
• Security
• 802.1x based, Pre-authentication supported, etc.
• RF Link layer
• Channel number, SSID, MAC Address, Rate, Phy
• Location
• X,Y,Z
• Operator, Service Provider information
• T-Mobile, ATT, etc.

4
General Information Format

• Global Network Map
• Network Identifier
• 802.11, 802.16, GSM, GPRS, WCDMA, etc.
• General Network Info
• Standards
• Security
• IP based
• Other Network Specific Information
• Link information and list of APs for 802.11
• List of Base Stations for 802.16 and access
  information
• Access information for Cellular Networks

Access Method

• 802.21 is defining a media independent method for
  accessing the structured information defined
  above
• Can be got at with 802 frames appropriate
  Ethertype
• ASN.1 format may level MIB access and enable .11k
  MIB to be accessed via .21 transport
