A communication method in which, when a UE 10 moves between cells having mutually different gateway devices (PGWs) corresponding thereto, first, a first PDN connection is handed over without changing the PGWs, and is changed to a path that passes through a base station device (eNB) for the cell serv...

Abstract A communication method in which, when a UE 10 moves between cells having mutually different gateway devices (PGWs) corresponding thereto, first, a first PDN connection is handed over without changing the PGWs, and is changed to a path that passes through a base station device (eNB) for the cell serving as the movement destination, after which a second PDN connection, which passes through the base station device of the movement destination and through the gateway device, is established. Furthermore, after the second PDN connection is established, the first PDN connection is disconnected. L'invention concerne un procédé de communication dans lequel, lorsqu'un UE 10 se déplace entre des cellules ayant des dispositifs de passerelle (PGW) mutuellement différents qui leur correspondent, une première connexion PDN est tout d'abord transférée sans changement des PGW, puis passe sur un trajet qui traverse un dispositif de station de base (eNB) relatif à la cellule servant de destination de déplacement, après quoi une deuxième connexion PDN, qui traverse le dispositif de station de base de la destination de déplacement et traverse le dispositif de passerelle, est établie. De plus, après que la deuxième connexion PDN a été établie, la première connexion PDN est déconnectée. 通信方法では、対応するゲートウェイ装置(PGW)が互いに異なるセル間をUE10が移動する際に、まず、PGWを変更せずに第1PDNコネクションをハンドオーバして移動先のセルの基地局装置(eNB)を経由する経路に変更した後、移動先の基地局装置及びゲートウェイ装置を経由する第2PDNコネクションを設ける。そして、第2PDNコネクションを設けた後に、第1PDNコネクションを切断する。
