The present invention provides a system, method, and apparatus for
providing improved quality of service in a wireless local area network
transmission system, the network comprising at least two devices, the
quality of services defined at least in part by data communicated by a
first of the devices to other devices in the network through one or more
quality of service parameters. In accordance with the present invention,
a change indicator is initialized at the start of a monitoring period.
Then, during the monitoring period, the stored parameters are monitored
for changes in those of thee stored parameters that define the quality of
service. When a change is detected, the change indicator is updated in
response and other devices in the network are periodically notified of
the current value of the change indicator. The other devices are operable
to update locally stored quality of service parameters in response to
detecting a change in the change indicator.
