802 21 media independent handover services
802.21: Media Independent Handover Services &?
  • 802.21: MI Handover services
    • 802.21a: Security for MI services
    • 802.21b: Extensions for MI downlink only technologies
    • 802.21.1(proposed): MI Emergency services
    • 802.21x(proposed): MI power management for multi-RAT devices
  • 802.21 does MI information sharing for coordination of services across RAT boundaries.
  • 802.21 framework and defined interfaces are suitable for whitespace coexistence coordination and spectrum management.
    • Between incumbents and unlicensed users (access to FCC dbase)
    • Among unlicensed users: RAT, location, frequency, time info coordination
    • Between 802 users and non-802 users: new interfaces may be added

Existing:

Media specific Interfaces for Handover

802.16g/h for 802.16

  • MIH Protocol (MAC independent messages) defined in 802.21
  • Container for MIH messages for 802.11 defined in 802.11u
  • Container and primitives for MIH messages for 802.16 defined in 802.16g/h
  • Working with 3GPP-SAE for 3GPP specific changes
  • Transport for MIH Protocol defined in IETF (MIPSHOP)

Media specific changes closely follow base protocol

802.21 MIC (Media Independent Coexistence) Measurements, Triggers, Network Information

802.22x for 802.22

802.16g/h for 802.16

  • MIC Protocol (MAC independent messages) defined in new 802.21x
  • Container for MIC messages for 802.11 defined in 802.11u
  • Container and primitives for MIH messages for 802.16 defined in 802.16g/h
  • Container for MIC messages for 802.22 to be defined in 802.22x
  • Containers for MIC messages for non-802 users possible
  • Transport for MIC Protocol to be defined in IETF (MIPSHOP)

Media specific changes closely follow coexistence

802 21 ideal for media independent coexistence work
802.21 Ideal for Media Independent Coexistence Work

Has established relationships with 802.11 & 802.16.

Has established relationship with IETF for higher layer and internet transport issues.

While SCC41/1900.4 may be ideal approach for cell/3G systems, 802.21 is best suited to serve unlicensed technology users.

802.21 does not impose general architecture

802.21 does not depend on network or terminal "manager".

802.21 approach is based on media-specific messaging for specific purposes.

802.21 effectively coordinates information sharing between RATs.

802.21 media independent server can facilitate access to FCC dbase and can "register" unlicensed users by location for coexistence purposes.

802.21 media independent server ideal for coordinating quiet periods across RATs for sensing.
