A user terminal receives, from a base station, a measurement request for measurement of a reception intensity of a signal transmitted from another user terminal that performs D2D communication, and a threshold value used to determine whether to transmit measurement information related to the reception intensity. The user terminal measures reception intensity of the signal on the basis of the measurement request, and transmits to the base station, the measurement information enabling the base station to perform controls of the D2D communication in response to the measurement information satisfying the threshold value. The user terminal receives from the base station a location request for transmission of location information indicating geographical location of the user terminal. In response to the location request, the user terminal transmits the location information periodically to the base station, the location information enabling the base station to perform controls of the D2D communication.
