doc.: IEEE 802.11-05/0897r0 Submission September 2005 Wolfgang Groeting, Siemens AGSlide 1 802.11u requirements covered by 802.21 Notice: This document has been prepared to assist IEEE 802.11. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document 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 Standards publication; 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 to reproduce 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 802.11. Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures, including the statement "IEEE standards may include the known 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 both mandatory 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 possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair as early 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 IEEE 802.11 Working Group. If you have questions, contact the IEEE Patent Committee Administrator at.http:// email@example.com@ieee.org Date: 2005-09-19 Authors:

doc.: IEEE 802.11-05/0897r0 Submission September 2005 Wolfgang Groeting, Siemens AGSlide 3 Glimpse of IEEE 802.21 – MIH Enable interoperability between different network types, including both 802 and non 802 (cellular) networks by supporting handover mechanisms Key services provided by.21: –Event Service –Command Service –Information Service Media Independent Handover (MIH) is present in terminal and in network
doc.: IEEE 802.11-05/0897r0 Submission September 2005 Wolfgang Groeting, Siemens AGSlide 4 MIH Basic Information Set An essential subset of Media Independent Information Service (MIIS) element Transport of MIIS element either –over media specific broadcast signal –by sending a specific request/response primitive –over higher layer protocols Envisaged to acquire MIIS element as soon as possible e.g. state 1 (still in discussion) –unauthenticated state –unassociated state

doc.: IEEE 802.11-05/0897r0 Submission September 2005 Wolfgang Groeting, Siemens AGSlide 8 Conclusion Afore mentioned requirements are covered if the following requirements are supported: –REQd16H1: Indicate MIH capability –REQd16H2: Transport mechanism for MIH elements in state 1 –REQd16H3: Define SAPs, primitives and event/state information to support IEEE 802.21 MIH functionalities. Open questions –Have.21 an.11u the same understanding of the information elements as roaming lists, interworking services, etc. ? –Which requirement(s) should be solved independently of the.21? All? A subset?
