Abstract
移動端末は、ハンドオーバが必要か否かを判定し(S1)、ハンドオーバが必要である場合、複数の無線基地局が発信した信号に関する移動端末の受信強度を測定する(S2)。管理装置は、前記測定により得られた受信強度のうちの下限値を超える受信強度に対応する無線基地局の通信エリアと、移動端末が接続している無線基地局の通信エリアとが隣接することを隣接エリア情報に記録する(S5)。無線基地局は、移動端末のハンドオーバのための無線基地局の候補を前記隣接エリア情報から選択し、当該候補に対し前記測定した受信強度に基づく優先順位を設定する(S7)。移動端末は、ハンドオーバの候補に対し前記優先順位に沿ってハンドオーバを実行する(S10)。
