Abstract: A user terminal is configured to execute processes of: receiving control information from a serving cell, the control information transmitted by a dedicated signaling to the user terminal, wherein the control information requests acquisition of device-to-device discovery parameters included in a system information block of different frequency than the serving cell, and the device-to-device discovery parameters include resource pool information used to device-to-device discovery; acquiring the device-to-device discovery parameters from a neighbor cell belonging to the different frequency designated by the control information; determining whether a valid period of the control information expires; and transmitting a message to the serving cell as long as within the valid period, the message including the device-to-device discovery parameters and an identifier of the different frequency.

Abstract: A mobile communication system 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 the data path does not pass through the core network. The system comprises a communication apparatus that assigns a radio resource to a D2D terminal that performs the D2D communication, wherein the communication apparatus performs assignment determination as to whether a dedicated radio resource not shared with the cellular communication is assigned to the D2D terminal or a shared radio resource shared with the cellular communication is assigned to the D2D terminal.

Abstract: A communication control method according to the present invention is a method for allowing a cellular communication system to cooperate with a wireless LAN system. The communication control method comprises: a detecting step of detecting, by a user terminal having a cellular communication unit and a wireless LAN communication unit, that the user terminal is present near a small-cell base station; a recognizing step of recognizing, by the user terminal, that the small-cell base station is of a collocated type where the small-cell base station is disposed at a same location as a wireless LAN access point; and a scanning starting step of starting, by the user terminal, scanning for discovery of the wireless LAN access point, when the user terminal has recognized that the small-cell base station is of the collocated type and has not discovered the wireless LAN access point.

Abstract: A UE performs a first communication with a base station provided in a cellular communication network and performs a second communication with an access point provided in a WLAN. The UE performs a cellular/WLAN interworking to perform a switch between the first communication and the second communication. The UE performs the switch between the first communication and the second communication based on a RAN assistance parameter provided from the cellular communication network. The UE determines, after an elapse of a predetermined time from an event that all of the first communication was switched to the second communication based on a first RAN assistance parameter provided as the RAN assistance parameter, whether to perform a switch from the second communication to the first communication based on a second RAN assistance parameter newly provided as the RAN assistance parameter.
