Dynamic update of quality of service (QoS) parameter set

A method of 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 all other devices in the network through one or more stored parameters, the method comprising the steps of:

• initializing a change indicator at the start of operation;
• stroring the change indicatora monitoring period;
• repeatedly during the monitoring period:
• monitoring the received change indicator for changes in the quality of service requirements;
• comparing the received change indicator to the most recently stored updating the change indicator in response to the monitoring step;
• in response to detecting a change in the change indicator, updating the stored quality of service parameters, and storing the new change indicator.

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 all other devices in the network through one or more stored parameters, the apparatus comprising:

• a quality of service coordinator for initializing a change indicator at the start of operation;
• memory for stroring the change indicator during a monitoring period;
• the quality of service coordinator operable during the monitoring period and further comprising:
• a frame processor for monitor the received change indicator for changes in the quality of service requirements;
• a comparator for comparing the received change indicator to the most recently stored updating the change indicator in response to the monitoring step;
• an updator operable, in response to detecting a change in the change indicator, to update the stored quality of service parameters, and to store the new change indicator.
