IEEE 802.16 ND&S
• 4 Steps of ND&S
• NAP Discovery
• NSP Discovery
• NSP Enumeration and Selection
• ASN Attachment based on NSP Selection
• Two deployment cases
• “NAP+NSP” deployment case
•
•
An ASN(Access Service Network) managed/owned by a single NSP
administrative domain
“NAP sharing” deployment case
•
An ASN managed by a NAP but shared by two or more NSPs.
• NAP Discovery
• DL-MAP of ASN
• Operator ID
•
Most significant 24 bits of “Base Station ID”

Base Station ID
Operator ID/NAP ID
• NSP IDs over SII-ADV and/or SBC-RSP
• Only when NSP Identifier Flag is set
• MS depends on the Configuration Information stored in the MS.
• NAP ID list, NSP ID list, NAP/NSP mapping list, NSP Change Count,
Mapping table between 24-bit NSP IDs and Corresponding realm of the
NSPs.
• Physical information, Security parameters, Network deployment mode.

Summary
• The amendment is for Media Independent Network
Discovery.
• Same mechanism as IEEE 802.11
• Stored information in the MS is very static.
• Information expected to be stored in the MS can be
obtained through information service.
• 802.21 IS can complement 802.16 ND&S
• Limitation of the length of query and query response
can be discussed.
