Abstract

移動局装置は、ハンドオーバー指示メッセージを受信したときにハンドオーバー情報を取得し、同期ハンドオーバーと判断した場合は、ハンドオーバー実行時間に至るまではソースセルにおける受信処理を継続する。ハンドオーバー実行時間になった場合、ハンドオーバー情報に従ってセル切り替え制御を行い、ターゲットセルに対して下り同期確立処理を開始する。下り同期確立がハンドオーバー保護時間の満了前に成功した場合で、かつ下り同期確立見込時間以内に下り同期確立が成功したかを判定し、成功したと判定した場合には、ターゲットセルに対して上り同期確立が不要と判断し、ランダムアクセスが不要な同期ハンドオーバー処理を行う。一方、成功していないと判定した場合には、ターゲットセルに対して上り同期確立が必要と判断し、ランダムアクセス送信が必要なハンドオーバー処理を行う。
