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.

October 2006 Problem description AP could serve STAs connecting to different SSPNs, so different QoS Map information for different SSPNs should be maintained by AP, and STAs which connect to different SSPNs should be able to get different QoS Map information from AP. When AP has any change in the QoS Map information, it may send the broadcast QoS Map Configure frame with the new QoS Map information to the STAs. However some STAs with corresponding QoS Map information unchanged in AP may also receive the broadcast QoS Map Configure frame. What should they do? Tony Mo, Huawei Technologies Co., Ltd.

October 2006 Proposal AP should do: When the STA sends a QoS Map Request frame to request the QoS Map information, AP should reply with a QoS Map Configure frame with the corresponding QoS Map Set, and the QoS Map Set should contain a Map ID. The Map ID is used to identify the current QoS Map Set. When AP has any change in the QoS Map information, it should send the QoS Map Configure frame with the new QoS Map Set, and the QoS Map Set should contain a Map ID. The Map ID is used to identify the new QoS Map Set. Tony Mo, Huawei Technologies Co., Ltd.

Proposal (Cont’d) STA should do: October 2006 Proposal (Cont’d) STA should do: When the STA receives the QoS Map Configure frame, and the frame is used to inform the STA the change in the QoS Map information, it should parse the Map ID in the QoS Map Set. If the value of the Map ID is equal to the Map ID that the STA saved, the STA should update its QoS Map Set with the new QoS Map Set, or else do nothing. Tony Mo, Huawei Technologies Co., Ltd.
