Harmonizing 802.11k MIB Access for Emerging Wireless Networks

This document outlines the requirements for harmonizing 802.11k Management Information Base (MIB) access. It emphasizes the need for an extensible information structure that is compatible with other emerging networks and existing formats such as ASN.1, XML, and TLV. The enhancement of network identification, access methods, and security standards across various wireless technologies, including 802.11 and GSM, is discussed. The use of standardized compilers and parsers facilitates easy parsing and understanding of this information, providing a foundation for cohesive network management.

  2. 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 David Johnston, Intel Corp

  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, AT&T, etc. David Johnston, Intel Corp

  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 David Johnston, Intel Corp

  5. Global Network Neighborhood Map Network_Id=802.11 Standard = {802.11a,802.11b,802.11g,802.11n} Network Type = IP Security = 802.1x Neighbor Map: List of 802.11 APs {SSID, MAC Address, Channel, Location, Phy} Network_Id=802.16 Standard = {802.16d,802.16e} Network Type = IP Security = PKM Neighbor Map: List of 802.16 BSs {ID, MAC Address, Frequency, Location, Phy } Network_Id=GSM Phy Type = TDMA Network Type = Circuit Switched Security = Neighbor Map: Access Information for various carriers David Johnston, Intel Corp

  6. Example ASN.1 format for 802.11 Network_Id=802.11 Standard = {802.11a,802.11b,802.11g,802.11n} Network Type = IP Security = 802.1x Neighbor Map: List of 802.11 APs {SSID, MAC Address, Channel, Phy, Location} • Network_Map ::= SEQUENCE { Network_Info Network-List} • Network-List ::= ENUMERATED {802.11,802.16,GSM,GPRS,WCDMA,….} • 802.11 ::=SEQUENCE { • Standards ::=ENUMERATED {802.11a,802.11b,802.11g…….} • Network_Type ::= ENUMERATED {IP,ATM…} • Security ::= ENUMERATED {802.1x, PKM, …} • Neighbor_Map ::= SEQUENCE OF AP_List ) • AP_List ::= SEQUENCE { • SSID ::= String (SIZE (1..32) ) • BSSID ::= NumericString (SIZE (8) ) • Channel ::= INTEGER • Phy ::= ENUMERATED (CCK,DSSS, OFDM ) • Location_Location-Info } • Location-Info ::=SEQUENCE { • X ::= INTEGER • Y :: INTEGER • Z :: INTEGER } • } David Johnston, Intel Corp

  7. 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 David Johnston, Intel Corp
