Multi-radio Device Priority Offset and Escalator Modules

The patent implements dynamic priority adjustment where the initial priority assigned to traffic is not fixed but adapts based on current medium occupancy conditions. When the medium is heavily occupied, the priority offset module reduces the initial priority increment, allowing lower priority traffic to access the medium sooner, thereby resolving the contradiction between fast access for time-sensitive traffic and excessive delay for non-time-sensitive traffic.

The system changes the priority parameter dynamically based on medium occupancy metrics. The priority offset module adjusts the initial priority value as a parameter, and the priority escalator module adjusts the increment rate, allowing the system to adapt priority assignments to current conditions, thus balancing access speed for high-priority traffic with fairness to lower-priority traffic.

The controller is segmented into distinct functional modules: a priority offset module that adjusts initial priority values, a priority escalator module that controls priority increment rates, and an arbiter that makes access decisions. This segmentation allows each module to perform a specific function, simplifying the overall complexity while achieving dynamic priority adjustment and improved medium access efficiency.

The system implements feedback mechanisms where the arbiter monitors medium occupancy and traffic patterns, and this information feeds back to the priority offset and escalator modules to adjust priority assignments. This feedback loop enables automatic adaptation to changing conditions without requiring complex manual configuration, improving efficiency while managing complexity through automated control.
