Abstract

　セル選択システムは、携帯電話ネットワークのセルと、このセルに包含されると複数のＷＬＡＮのセルとを有するネットワークにおいて、携帯端末（１）が通信に用いるセルを選択するセル選択システムである。携帯電話ネットワークのセルでは、セル選択情報を含む報知情報が送信される。このセル選択情報は、第２のセルより少ないパターンのセル切替え判断用のパラメータを有する。携帯端末（１）は、携帯電話ネットワークの報知情報からセル選択情報を読み出し、ＷＬＡＮの報知情報を用いて当該第２のセルに対する切替え判断に用いるパラメータを決定し、決定したパラメータを用いてセルの切替えの可否を判断する。携帯電話ネットワークのセルに含まれるＷＬＡＮのセルの数が増えても報知情報のデータ量を抑制できるセル再選択システムを提供する。
