Abstract

無線ネットワーク制御装置から前記基地局装置へ順次送信されるフレームの送信タイミングを調整する場合に、必要なTiming Adjustmentコントロールフレーム（ＴＡ）に反応して、フレーム送信スケジュールを適切に変更する。受信したＴＡを無視する時間である第一の時間内において前記フレームの送信タイミングの調整を抑止するように制御する。また、第一の時間外においては、無線ネットワーク制御装置と基地局装置との間の伝送遅延量の変化に応じて第一の時間を変化させる。無線基地局装置から無線ネットワーク制御装置へ通知される第一のコントロールフレームを無視する時間を設け、この時間を変動値にすることで、確実な同期制御を実現できる。
