Abstract

 端末装置のセル切り替え時の通信スループットの低下を防止する基地局装置及びセル切り替え決定方法を提供する。当該基地局装置は、端末装置の選択セルにおける通信スループットを各セル内の端末装置についてそれぞれ合計し、セル単位の通信スループット合計値を算出する算出手段と、端末装置により生成される選択セル及び複数セルのうちのその他1つの移動先セルの受信品質情報を受信する受信手段と、この受信手段により受信された選択セルの受信品質情報と移動先セルの受信品質情報との差分を得ることにより、端末装置がセル切り替え区間内に属するか否かを判定する判定手段と、端末装置が当該セル切り替え区間内に属すると判定された場合に、選択セル及び移動先セルに関する、上記算出手段により算出されるセル単位の通信スループット合計値を比較することにより、当該移動先セルを新たな選択セルとしてセル切り替えを決定する決定手段とを備える。
