Abstract
(EN)
A mobile terminal (3) judges if it can move during a DTX period in an active mode or not. If it can, a message to the effect that it can is sent to a base station (2). When the base station (2) receives the message from the mobile terminal (3), and if the base station (2) judges that it can move during a DRX period in the active mode, the power supply to a data transmitting section and a data receiving section of the mobile terminal (3) is temporarily stopped.
(FR)
La présente invention concerne un terminal mobile (3) qui décide s'il peut ou non se déplacer pendant une période de transmission discontinue dans un mode actif. S'il peut le faire, un message à cet effet est envoyé à la station de base (2). Quand la station base (2) reçoit le message de la part du terminal mobile (3), et si la station de base (2) juge qu'il peut se déplacer pendant une période de transmission discontinue dans le mode actif, l'alimentation électrique à la section de transmission de données et à la section de réception de données du terminal mobile (3) est arrêtée temporairement.
(JA)
 移動端末3がActive中のDTX期間に移行することが可能であるか否かを判定し、Active中のDTX期間に移行することが可能である場合、その旨を基地局2に通知し、基地局2が移動端末3からの通知を契機にして、Active中のDRX期間に移行することが可能である旨の判定を行えば、移動端末3のデータの送信処理部及び受信処理部に対する電源の供給を一時的に停止する。
