RADIO QUALITY MANAGEMENT DEVICE, RADIO QUALITY MANAGEMENT METHOD, AND PROGRAM

To provide a radio quality management device capable of preventing deterioration in communication quality due to increase in wireless slave units.SOLUTION: A radio quality management device includes: a monitoring unit that monitors transmission intervals of a plurality of radio frames transmitted from a plurality of wireless slave units to a wireless master unit; a discriminating unit that discriminates, among the plurality of wireless slave units, a wireless slave unit whose transmission interval is equal to or more than a first threshold value and a wireless slave unit whose transmission interval is less than the first threshold value; and a change command unit that outputs a change command to change a current accommodation channel in which a target wireless slave unit is accommodated to another channel by setting at least one of one or more wireless slave units whose transmission interval is equal to or more than the first threshold as the target wireless slave unit, and by setting at least one of one or more wireless slave units whose transmission interval is less than the first threshold and selected on the basis of values of wireless quality index information extracted from radio frames transmitted from the wireless slave units as the target wireless slave unit.SELECTED DRAWING: Figure 1 【課題】無線子機の増加に伴う通信品質の劣化を抑制可能な無線品質管理装置を提供する。【解決手段】無線品質管理装置は、複数の無線子機から無線親機にそれぞれ送信される複数の無線フレームの送信間隔を監視する監視部と、複数の無線子機のうち、送信間隔が第１閾値以上となっている無線子機、および送信間隔が第１閾値よりも小さいものとなっている無線子機をそれぞれ判別する判別部と、送信間隔が第１閾値以上となっている１台以上の無線子機のうちの少なくとも１台を対象無線子機とすると共に、送信間隔が第１閾値よりも小さい無線子機であって、該無線子機から送信された無線フレームから抽出される無線品質指標情報の値に基づいて選定される１台以上の無線子機のうちの少なくとも１台を対象無線子機として、対象無線子機が収容されている現収容チャネルを他のチャネルへ変更するための変更命令を出力する変更命令部と、を備える。【選択図】 図１
