Abstract

　長時間待ち受けを実現するため消費電力を削減しながらリセレクション処理を確実に行って上位通信システムを待受ける機会を増やしトラフィックの効率化を図ることが可能な携帯端末装置およびその通信方法、並びに無線ネットワークシステムであって、携帯端末装置１０は、通信部１を介して現在通信中の基地局から近隣基地局情報を取得し、使用中の通信システムにおける信号強度を監視し、現在の信号強度が所定量より低下すると、近隣基地局情報に記憶される現在使用中の通信システムとは異なる通信システムへのハンドオフを行い、現在使用中の通信システムのセッションを開放するとともに、他の通信システムに対して捕捉試行を行い、近隣基地局情報に、現在使用中の通信システムと異なる通信システムを示す情報が含まれている場合には、リセレクション処理を抑制する第１のモードとし、含まれていない場合にはリセレクション処理を抑制しない第２のモードとするリセレクション抑制処理を実行する制御部８を有する。
