The present disclosure relates to a method of radio resource management for a communication network including an Access Controller and a plurality of Access Points. The Access Controller manages the plurality of Access Points, each of which provides a radio for accessing the network. The Access Controller (AC) creates a high-density group and joins a present radio and, with respect to the present radio, radios having signal strengths higher than a power-adjustment threshold into the high-density group, when it determines that the transmission power of the present radio is less than or equal to a minimum transmission power threshold, and that the difference between a first parameter that is the signal strength with respect to the present radio of a radio having the weakest signal strength amongst the radios having signal strengths higher than a power-adjustment threshold and a second parameter that is the power-adjustment threshold is higher than a predetermined down-adjustment interval. The AC changes at least one of the radios in the high-density group from an ON state, in which communication is enabled, to an OFF state, in which communication is disabled, when the number of radios in the high-density group is greater than the number of a plurality of available channels. The AC assigns a channel from amongst the plurality of available channels to each of the radios in the high-density group, and adjusts the transmission power of a radio in the high-density group to the smaller of a predetermined configuration power and a maximum power if the status of the radio is changed after a channel is assigned. |
