Abstract

　本発明は、ハンドオーバ処理時のスループット低下を抑制できるようにしたもので、このために、無線端末（２）と、当該無線端末（２）と無線により通信する複数の無線基地局（３）とをそなえ、前記無線基地局（３）と前記無線端末（２）との間の信号の送受信に要する時間に応じて生成されるタイマ値のタイムアウトによって、前記無線基地局（３）と前記無線端末（２）との間の通信速度を低下制御する無線通信システム（１）において、前記無線基地局（３）が、前記無線端末（２）からの要求に応じて、又は、自律的に、前記無線端末（２）に関して他の無線基地局（３）へのハンドオーバ処理の実行を決定すると、前記無線端末（２）との間の通信速度を低下制御して前記タイマ値を増加させ、その後に、前記ハンドオーバ処理を実行する。
