Abstract: A base station according to an embodiment includes a controller configured to perform a process of transmitting, in a specific frequency band shared by a plurality of operators and/or a plurality of communication systems, a burst signal including data or a control signal and a discovery reference signal including a reference signal and/or a synchronization signal. If there is a transmission duration of the discovery signal within a transmission duration of the burst signal after starting the transmission of the burst signal, the controller performs a process of transmitting the discovery reference signal even within the transmission duration of the burst signal.

Abstract: 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.

Abstract: A broadcast multicast service center (BM-SC), chipset therefor, and a user terminal are for a mobile communication system including a general cell that supports broadcast delivery of Multimedia Broadcast Multicast Services (MBMS) data and a specific cell that does not support broadcast delivery of MBMS data. The BM-SC includes a processor and memory communicatively coupled to the processor. The processor is configured to either transmit or receive first information to mobile terminal via the specific cell, where the first information is originally transmitted in a transmission path that does not include the general cell, and the transmission path is from the BM-SC to the user terminal. The first information includes information indicating a geographical area in which the MBMS data is delivered, information indicating a frequency at which the MBMS data is delivered, and information indicating an identifier of service by which the MBMS data is provided.

Abstract: A communication method according to an embodiment comprises: a step of performing, by a user terminal, a reselection of a target cell to be used as a serving cell from among a plurality of cells operated at different frequencies. The step of performing the reselection of the target cell comprises: a first reselection step of performing, by the user terminal, the reselection of the target cell in a response to reception of a paging signal for requesting the reselection of the target cell from a current serving cell; and a second reselection step of performing, by the user terminal, the reselection of the target cell in a response to a trigger without dependence on the paging signal. In the first reselection step, the user terminal starts measurement of a quality of a measurement target frequency included in system information broadcast from the current serving cell, in response to the reception of the paging signal.

Abstract: A user terminal includes a controller that performs selection of an access network in which the user terminal exchanges traffic from among a cellular RAN (Radio Access Network) and a WLAN (Wireless Local Area Network). The controller stores a RAN rule for determining traffic steering to a WLAN having a RAN provided identifier (ID), receives a WLAN ID broadcasted from a cellular base station (BS), applies the WLAN ID to the RAN rule to determine whether to perform traffic steering, roaming from the RAN to another RAN, determines whether to acquire another WLAN ID provided by the other RAN based on a policy established by the RAN, receives the other WLAN ID from a second BS of the other RAN, and applies the other WLAN ID to the RAN rule to determine whether to perform traffic steering to the WLAN having the other WLAN ID, in the second cellular RAN.

Abstract: A network selection control method is a method for selecting, from a E-UTRAN and a WLAN, an access network in which a traffic of a UE 100 is transmitted and received. The network selection control method comprises the steps of: transmitting, by a cell #1 in the E-UTRAN, offload control information to a UE 100-1 that exists in the cell #1, the offload control information being for requesting switching of an access network in which the traffic of the UE 100-1 is transmitted and received, to the WLAN; and transmitting, by a cell #2 neighboring the cell #1 in the E-UTRAN, to a UE 100-2 that exists in the cell #2, neighboring cell offload information indicating that the offload control information is transmitted in the cell #1.
