Abstract

　アダプティブアレイアンテナを備えた複数の無線基地局1と、通信制御装置2とを含む通信システムにおける通信制御方法であって、互いに隣接する無線基地局1-1，1-2による干渉領域を示す位置情報と、干渉領域に無線基地局1-1がビームを向けるための第１重み係数、無線基地局1-2がビームを向けるための第２重み係数と、を対応させて干渉テーブル23に記憶し、無線基地局1-1が端末3と通信中に、無線基地局1-1，1-2がそれぞれ適用している重み係数を取得して、干渉テーブル23に記憶されている第１,第２重み係数との比較に基づいて、端末3が干渉領域に位置するか否かを判定し、干渉領域に位置する場合には、干渉しないように無線基地局1-2のビーム生成を制御する。これにより、隣接する無線基地局に干渉されることなく、安定して通信できるようにする。
