Abstract

A method is provided for passing management frames between a network coordinator and a plurality of devices during a plurality of repeating superframes. The superframes are divided into repeating groups of consecutive superframes that form a superframe cycle. Each superframe has a set number of management time slots in it, which number can change. This creates a number of unique management time slots in each superframe cycle based on the number of superframes per cycle and the number of management time slots per superframe. The devices are assigned to a number of contention groups equal to the total number of management time slots in a superframe cycle. Each contention group is assigned a unique management time slot, and each device can only send management requests to the coordinator during the unique management time slot assigned to its contention group.
