Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.org/guides/bylaws/sb-bylaws.pdf>, 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 <stuart.kerry@philips.com> 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.

Month Year doc.: IEEE 802.11-yy/xxxxr0 September 2005 Abstract Review of requirements for the Mobility Domain for the purpose of BSS Transition. Propose changes to the TGr draft which combine the Resource Mobility Domain and Security Mobility Domain concepts. The text changes for Mobility Domain are included in Document 11-05/0867r0 Michael Montemurro, Chantry Networks John Doe, Some Company

September 2005 Background Currently, the TGr draft introduces Resource Mobility Domain and Security Mobility Domain. Practically speaking, the security domain is really governed by the R0 Key Holder (or possibly a set of R0 key holders). A STA can only BSS-Transition to: Another BSS in the ESS A BSS that advertises the same R0KeyHolder Michael Montemurro, Chantry Networks

Mobility Domain Requirements September 2005 Mobility Domain Requirements Allow a STA to determine which AP’s are BSS-transition targets. Identify the AP as reachable over the DS. A STA can only BSS-Transition to a target AP only if the AP is part of the same Mobility Domain and shares the same R0KeyHolder. This implies that the Security Domain is the same as the Mobility Domain. Michael Montemurro, Chantry Networks

Mobility Domain Definition September 2005 Mobility Domain Definition A set of BSSs, within the same ESS, identified by a Mobility Domain Identifier that provide the following assurances to the STA: fast transition is possible between any two BSSs using either "over the DS" or "over the air" procedures. a common key infrastructure is accessible at all BSSs common network services are accessible through all BSSs. Michael Montemurro, Chantry Networks

Protocol Requirements September 2005 Protocol Requirements The Mobility Domain will be advertised by the Mobility Domain IE. The Mobility Domain IE will be included by the AP in the Beacon and Probe Response messages. Michael Montemurro, Chantry Networks

Mobility Domain IE Element ID Length Mobility Domain Identifier September 2005 Mobility Domain IE Element ID Length Mobility Domain Identifier Octets: 1 1 6 The Mobility Domain Identifier is unique for each network and specified with 6 octets. The Mobility Domain Identifier is included in the Beacon and Probe Response messages. Michael Montemurro, Chantry Networks

Summary of Text Changes September 2005 Summary of Text Changes Change all references to Resource Mobility Domain and Security Mobility Domain to Mobility Domain. Remove all references to Resource Mobility Domain Identifier and Security Mobility Domain Identifier. Add the definition of Mobility Domain IE and add the IE to the Beacon and Probe Response messages. The changes are captured in Document 11-05/xxxxr0 Michael Montemurro, Chantry Networks

September 2005 Motion Instruct the editor to incorporate the changes into the TGr draft as described in document 11-05/0867r0. Michael Montemurro, Chantry Networks
