MOBILE COMMUNICATION SYSTEM, USER TERMINAL, AND BASE STATION

摘要

A mobile communication system according to an embodiment supports a cellular communication in which a data path passes through a network and a D2D communication that is a direct device-to-device communication in which a data path does not pass through the network. The mobile communication system comprises: an eNB 200 included in the network and configured to transmit D2D broadcast information; and a UE 100 configured to perform the D2D communication after receiving the D2D broadcast information from the eNB 200. The D2D broadcast information is information that enables the D2D communication even though the UE 100 is in a specific state in which a connection with the network is not established. The UE 100 performs the D2D communication in the specific state on the basis of the D2D broadcast information.
