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 Working Group.

The elements involved in AN QoS
Wu/app. layer/SIP/RSVP AS ?
STA
DSM
Gateway
Upper Layer AP
Integration/Portal
QoS Mapping 1
QoS Mapping 2
11 MAC
11 MAC
Wireless Media QoS
DS QoS
Two aspects of the QoS in the AN
Wireless Media QoS – controlled by 11e
DS QoS -- (in scope/out of scope?)
Two mappings
At STA from user applications/e2e QoS controls, e.g. SIP, RSVP/NSIS
At AP/Gateway from the user profile/SSPN (AAA) information
Location depends on the location of the AN QoS control function.
Used for admission control, e.g. to decide if a 11e request is acceptable

5. What is in scope QoS mapping/control is in TGu scope Interface “?”
July 2005
What is in scope
QoS mapping/control is in TGu scope
The two mappings needs to follow the same standard, from different source of information
In scope since the mapping is into the wireless media QoS, and only 11 can do it (11e parameters makes no sense to external layer)
Interface “?”
Source of the information/interface needs to be specified
DS QoS
DS details is out of scope
What information needs to be provided to allow possible DS QoS control in scope

6. Conclusions QoS in the WLAN has two parts, over the air, and the DSM

Conclusions
QoS in the WLAN has two parts, over the air, and the DSM
Standard way of QoS mapping is necessary for the admission control
QoS issue cannot be left to 802.1, since it is within the 11 layer.
