Abstract: A mobile communication system comprises: a base station configuring a D2D supporting cell that supports D2D communication that is direct device to device communication; and a user terminal that performs the D2D communication in the D2D supporting cell. The base station comprises a control unit that controls handover of the user terminal. The control unit controls the handover on the basis of a support state of the D2D communication in a cell to which the user terminal performs handover.

Abstract: A mobile communication method in which a radio terminal connects to a network so as to perform a communication, comprises: a step in which the radio terminal detects an occurrence of a connection failure with the network in a connected state; and a step of sending a radio link failure (RLF) report regarding the detected connection failure, from the radio terminal to the network. In the step of sending the RLF report, the radio terminal sends time information, which is contained in the RLF report, for identifying a time of occurrence of the connection failure, to the network.
