Abstract: A mobile relay station (RS) and a handover method thereof are provided. When it is determined that a mobile RS performs handover from a superordinate base station (BS) to a target BS, information indicating admission of handover is received from the superordinate BS. The mobile RS transmits a service unavailability section to a subordinate terminal, whereby the subordinate terminal is prevented from performing handover to a different BS or a different RS.
Abstract translation: 提供了一种移动中继站（RS）及其切换方法。 当确定移动RS执行从上级基站（BS）到目标BS的切换时，从上级BS接收到指示接纳切换的信息。 移动RS将服务不可用部分发送到下级终端，由此防止下级终端对不同的BS或不同的RS进行切换。
