Introduction

• IEEE 802.16(e) is different from IEEE 802.11 or
  3G.
• Complete description of IPv6 operation over IEEE
  802.16(e) is not present in IEEE 802.16 and
  WiMAX specs.
• IPv6 operations over IEEE 802.16(e) can benefit
  from IETF inputs and specifications.

Problem Statements

• Transmission of IPv6 Packets over IEEE 802.16(e)
  is not yet specified.
• Whats investigated.
• Default link MTU size 2041 octets
• Path MTU Discovery needs to be performed.
• Usage of MAC address in IEEE 802.16(e)
• Not used for IP packet transmission
• IP to Connection I-D mapping does happen for IP
  packet transmission
• Does this imply there is no need to perform
  address resolution, IP to MAC even it has MAC
  address ?
• Stateless Auto-Configuration and link local
  address configuration is possible using 48-bit
  universal MAC address.

Problem Statements (2)

• How to configure an IPv6 link needs to be
  specified, because this impacts the basic IPv6
  operation like NDP.
• Cellular way
• Separate IPv6 links between each SS and BS
• Ethernet way
• Common IPv6 link among SSes under an IPv6 router
  whether they are connected to one BS or not.
• No multicast connection in IEEE 802.16(e) which
  can be used for multicasting IPv6 control packets
  like NDP.

Problem Statements (3)

• FMIPv6 over IEEE 802.16e work
• Predictive Mode support
• Informational RFC through MIPSHOP WG
• IP multicasting MBS interworking
