According to this embodiment, the communication quality of the other base stations which are the candidates of the handover destination may be notified to the terminal device, and thus the process for causing a handover to the other base station having a sufficient communication quality to be performed can be executed. For example, the terminal device can prevent the handover from being performed to a base station with a large communication delay by reporting the radio quality for the other base station having a small communication delay, and not reporting the radio quality for the other base station having a large communication delay. The terminal device may handle the radio quality for another base station having a large communication delay as a value lower than the measured value, or may handle the radio quality for another base station having a small communication delay as a value higher than the measured value.

Optionally, the communication quality includes a communication delay.

According to the embodiment, the communication delay of the other base station of the handover candidate may be notified to the terminal device, and thus the process for causing a handover to be performed to the other base station having a small communication delay can be executed.

Optionally, the terminal device is notified of the third information by medium access control (MAC) signaling or radio resource control (RRC) signaling. According to this embodiment, the base station may perform fine control in order to perform signaling for each terminal device.

The first information optionally comprises a measurement report of a radio quality by the terminal device.
