Purpose:This is a response to a Call for Contributions on IEEE P802.16g

Notice:This document has been prepared to assist IEEE 802.16. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in thisdocument is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein.

Release:The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standardspublication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others toreproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.16.

IEEE 802.16 Patent Policy:The contributor is familiar with the IEEE 802.16 Patent Policy and Procedures <http://ieee802.org/16/ipr/patents/policy.html>, including the statement "IEEE standards may include theknown use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with bothmandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibilityfor delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair <mailto:[email protected]> asearly as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE802.16 Working Group. The Chair will disclose this notification via the IEEE 802.16 web site <http://ieee802.org/16/ipr/patents/notices>.

• Different Handover scenarios– Intra-802.16 subnet (no IP address change)

• 802.16 HO Function triggers handover– Inter-802.16 subnet

• Same Domain: 802.16 HO Function sends trigger to mobile IP• Different Domain: 802.16 HO Function sends trigger to 802.21

Conclusion

• The proposed 802.16 architecture and reference modelsaddress both 802.16 specific and higher layer (inter-technology) handoffs

• It is consistent with the proposed 802.21 architecture.

• 802.16 should select one of the logical and physicalnetwork architecture models that have been proposed

• Recommend adoption of the proposed reference model for802.16g– RRM&HO sub-layer added to the management plane
