Method and device for regulating power

Abstract

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.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for adjusting power. Background technique [0002] The propagation of wireless signals is affected by the surrounding environment, and problems such as multipath will cause complex attenuation phenomena of wireless signals in different directions. Therefore, the implementation of WLAN networks often requires careful network planning. Even after the wireless network is successfully deployed, parameter adjustment in the application stage is still necessary, because the wireless environment is constantly changing, and the interference caused by moving obstacles and working microwave ovens may affect the wireless signal. Propagation is affected, so radio frequency resources such as channels and transmit power must be dynamically adjusted to adapt to changes in the user environment. Such an adjustment process is complicated and requires extensive te...

Problems solved by technology

[0005] The traditional radio frequency power control method is to statically set the transmission power to the maximum value and simply pursue the signal coverage, but too much power may cause unnecessary interference to other wireless devices
