Abstract: The objective of the invention is to quickly switch base stations that are communication apparatuses via which a terminal communicates with a network. At a step (S91) a user terminal (UE) requests a data download from a first base station (eNB). At a step (S11) the user terminal (UE) provides notification of establishment of a communication path between the user terminal (UE) and a second base station. If the download is completed at a step (S94) the second base station (eNB) requests a handover from the first base station (eNB) at a step (S24). At this moment the first base station (eNB) makes no handover decision.
