PROBLEM TO BE SOLVED: To provide a technique for suitably performing radio communication between radio sets by utilizing a directional antenna by a radio communication control system and also suppressing an influence of phasing between the radio sets as much as possible.SOLUTION: A radio communication control system comprises a first radio set having a directional antenna, a second radio set, a directivity control part which controls directivity of the directional antenna of the first radio set, and a directivity information storage part which stores directivity information associated with directivity applied to the directional antenna of the first radio set according to a plurality of change patterns indicative of temporal change in reception signal intensity as to radio communication between the first radio set and second radio set. The directivity control part acquires temporal change in reception signal intensity in radio communication between the first radio set and second radio set, selects directivity information corresponding to a change pattern corresponding to the temporal change in reception signal intensity out of directivity information stored in the directivity information storage part, and applies the selected directivity information so as to carry out the radio communication between the first radio set and second radio set.SELECTED DRAWING: Figure 1 【課題】無線通信制御システムにおいて、指向性アンテナを利用するとともに、無線機間でのフェージングの影響を可及的に抑制し、無線機間の無線通信を好適に行う技術を提供する。【解決手段】指向性アンテナを有する第１無線機と、第２無線機と、第１無線機の指向性アンテナの指向性を制御する指向性制御部と、第１無線機と第２無線機との間の無線通信に関し、受信信号強度の時間的変化を示す複数の変化パターンの夫々に応じて第１無線機の指向性アンテナに適用される指向性に関する指向性情報を格納する指向性情報格納部とを備え、指向性制御部は、第１無線機と第２無線機との間の無線通信時に受信信号強度の時間的変化を取得し、指向性情報格納部に格納されている指向性情報の中から、当該受信信号強度の時間的変化に相当する変化パターンに応じた指向性情報を選択し、該選択した指向性情報を適用して第１無線機における第２無線機との無線通信を実行する。【選択図】図１
