    摘要: A radio terminal according to an embodiment is used in a mobile communication system. The radio terminal includes a controller configured to, if the radio terminal is in an RRC connected state, perform a predetermined function according to configuration parameters configured from a network. The controller is configured to invalidate at least a part of the configuration parameters in response to the transition of the radio terminal from the RRC connected state to a specific state. The specific state is a state in which signaling is reduced as compared with the RRC connected state and context information of the radio terminal is maintained in the network.

    摘要: A mobile station receives from a network a first minimization of drive test (MDT) configuration configuring a multicast-broadcast single-frequency network (MBSFN) measurement, and performs and logs measurement based on the configuration. When logged measurement is non-MBSFN measurement, the mobile station transmits a non-MBSFN measurement availability indicator to the network at a timing of handover, where the indicator indicates an availability of logged non-MBSFN measurement. When logged measurement is MBSFN measurement, the mobile station transmits an MBSFN measurement availability indicator to the network at a timing of handover in response to the MBSFN measurement being not ongoing, where the indicator indicates an availability of logged MBSFN measurement. The mobile station refrains from transmitting availability indicator to the network at the timing of handover in the network in response to the MBSFN measurement being still ongoing, even if the mobile station has the logged MBSFN measurement at the timing of handover.

    摘要: A radio base station is operable to transmit to a radio terminal a measurement configuration message for causing the radio terminal to perform a logging process of storing a measurement log including a measurement result of a radio environment, and to acquire the measurement log stored by the radio terminal. The radio base station includes a receiver configured to receive, from the radio terminal, log storing information indicating that the measurement log is stored in the radio terminal, and a transmitter configured to transmit, to the radio terminal, a log transmission request to request a transmission of the measurement log on the basis of the log storing information. The receiver is configured to receive, from the radio terminal, a log transmission response for carrying the measurement log and the log transmission response even when the measurement log is not stored in the radio terminal.

    摘要: A user terminal comprises a receiver configured to receive, configuration information configuring measurement for a queuing delay of data packet in an uplink, from a radio base station in a dedicated manner; a controller configured to perform the measurement; and a transmitter configured to report a result of the measurement to the radio base station per unit time. The configuration information includes information indicating length of the unit time and threshold information indicating a threshold related to the queuing delay. The controller is configured to perform the measurement per unit time. The transmitter is configured to report the result of the measurement upon measuring the queuing delay exceeding the threshold within the unit time. The transmitter is configured to not report the result of the measurement upon measuring the queuing delay not exceeding the threshold within the unit time.

    摘要: In a communication control method according to a present embodiment, at least one radio terminal of a first radio terminal and a second radio terminal discoveries the other radio terminal by executing a discovery for discovering a proximal terminal. The at least one radio terminal reports, to a network apparatus that the other radio terminal is discovered. The network apparatus requests, while the first radio terminal is located within a coverage of a cell, at least one of the first radio terminal and the second radio terminal to make a preparation for executing a relay by the second radio terminal by utilizing a proximal service.

    摘要: A base station, a processor thereof, and a communication control method thereof receive a notification from a first user terminal before starting direct device to device (D2D) communication, the notification indicating a desire for performing D2D communication, receive a measurement report including results of measurement of a cell reference signal from the first user terminal, and based on the measurement report, determine to cause the first user terminal to perform D2D communication, perform a process for starting the D2D communication between the first and second user terminals, receive a first data amount notification indicating an amount of first data to be transmitted from the first user terminal to the second user terminal, and based on the first data amount notification, allocate first radio resources to the first user terminal, where the allocated first radio resources are used by the first user terminal to transmit the first data.
