Abstract

　無線通信システムは、複数の下位局の将来予測情報を取得する第１取得部と、通信開始局について直近予測情報を取得する第２取得部と、複数の下位局のチャネル使用情報を取得する第３取得部と、第１取得部によって取得された将来予測情報と第３取得部によって取得されたチャネル使用情報とに基づいて、無線チャネルの使用確率を複数の無線チャネル毎に算出する算出部と、算出部によって算出された無線チャネルの使用確率に基づいて、複数の無線チャネルの中から、通信開始局に割り当てる無線チャネルを決定する決定部とを備える。算出部は、通信開始局の将来予測情報及び通信開始局の直近予測情報に基づいて、無線チャネルの使用確率を補正する。
