Abstract

　アクセスポイント探索方法は、所定のアクセスポイントのチャネルの情報を含むプロファイル情報を記憶するプロファイル記憶部３０５と、スキャン周期を設定するスキャン間隔設定部３１１と、パッシブスキャンを行いビーコン信号を検出するパッシブスキャン部３１５と、アクティブスキャン部３１７と、を備えた無線ＬＡＮ端末がアクセスポイントを探索する方法であって、アクティブスキャン部３１７がアクティブスキャンを行う前に、スキャン周期ごとに、パッシブスキャン部３１５がパッシブスキャンを実行し、アクセスポイントから送信されたビーコン信号を検出した後、アクティブスキャン部３１７がアクティブスキャンを行い、アクセスポイントを探索する。
