TERMINAL DEVICE, BASE STATION DEVICE, COMMUNICATIONS SYSTEM, AND COMMUNICATIONS METHOD

摘要

A terminal device includes: a wireless communication unit that performs wireless communication; a connection control unit that connects to a first base station device so as to be able to wirelessly communicate with the first base station device via the wireless communication unit, the first base station serving as a primary, the connection control unit connecting to a second base station device so as to be able to wirelessly communicate with the second base station device via the wireless communication unit, the second base station device serving as a secondary; a detection unit that determines whether quality of wireless communication between the terminal device and the first base station device is in a low state based on a predetermined condition; and a signal transmission control unit that wirelessly transmits via the wireless communication unit, a predetermined signal toward at least either the first or second base station device when the quality is determined to be in the low state by the detection unit.
