Abstract: A mobile communication system supports cellular communication in which data communication is performed between a network and a user terminal and D2D communication in which data communication is directly performed among two or more user terminals. The D2D communication is performed by using a part of the uplink radio resources of the cellular communication. The uplink radio resources include a specific radio resource that is used in the transmission of a predetermined uplink signal in the cellular communication. The use of the specific radio resource in the D2D communication is regulated.

Abstract: A communication control method is used in a mobile communication system that supports cellular communication in which a data path passes through a core network, and D2D communication that is direct device-to-device communication in which a data path does not pass through the core network. The communication control method comprises: a transmission step of transmitting, by a first user terminal that camps on a cell of a first base station, a discovery-use signal related to the discovery of a proximal terminal be capable of a communication partner of the D2D communication; and a notification step of notifying, by a communication device, the first base station of interference information related to the received discovery-use signal in response to the communication device receiving the discovery-use signal.

Abstract: A user terminal employed in a mobile communication system including a general cell supporting PTM distribution of MBMS data and a specific cell not supporting PTM distribution of the MBMS data, the user terminal receives a connection establishment message for establishing a connection between the user terminal and the general cell from the general cell when the user terminal is in an idle mode with the general cell selected as a serving cell. The user terminal sends an establishment completion message indicating completion of establishment of the connection in response to the connection establishment message received from the general cell. The user terminal sends the general cell a proximity notification that the specific cell exists near the user terminal if the specific cell exists, together with the establishment completion message.

Abstract: A mobile communication method is applied to a mobile communication system including a general base station and a specific base station. A distance between an edge closest to the general base station among edges of a coverage area of the specific cell and the general base station is a distance LMIN.
