Abstract: A foldable assembly which is configured to bear a flexible display. The foldable assembly includes a rotating shaft; a first mechanical part and a second mechanical part, where the first mechanical part and the second mechanical part are rotatably connected by using the rotating shaft; and a first protective structure, where the first protective structure is connected to an end face that is of the rotating shaft and that extends out of a periphery of the flexible display. A first surface of the flexible display is away from the rotating shaft, and the first protective structure is higher than or flush with the first surface of the flexible display, so that when the foldable display terminal falls, the first protective structure is in contact with a point of collision earlier than the flexible display.

Abstract: Embodiments of the present invention relate to a radio link reestablishment method and a controller. The method includes: if after sending downlink signaling or downlink data for designated times, a controller receives no corresponding acknowledgment returned by a user equipment in a cell dedicated channel state, or the controller receives a radio link failure indication message sent by a base station corresponding to the user equipment, the controller instructs the user equipment to re-search for a cell to trigger a cell update procedure, thereby improving reliability of a communications service, and ensuring normal running of the communications service.
