Abstract

　不特定のユーザがアクセスできるマクロセルと、特定のユーザしかアクセスできないクローズドセルとが混在する移動通信システムで使用されるユーザ装置は、在圏セルからの信号の品質をアイドル状態で所定の周期で測定する手段と、隣接セルからの信号の品質を所定のセルサーチ周期で行う手段と、セルサーチ結果に応じてセル再選択を行う手段とを有する。マクロセルの周波数とクローズドセルの少なくとも一部の周波数とが同じである。当該ユーザ装置がマクロセルに在圏し、所定の再選択条件が満たされた場合、在圏セルに隣接するクローズドセルが待受を行うセルとして再選択される。所定の再選択条件は、クローズドセルからの信号の品質が、在圏セルからの信号の品質より所定の閾値以上良い状態が、所定の再選択期間以上続くことである。
