Abstract: A radio terminal (3) can perform carrier aggregation using a first cell (10) of a first radio station (1) and a second cell (20) of a second radio station (2). The first radio station (1) performs, with the radio terminal (3), radio resource control for the first cell (10) and the second cell (20) in order to perform the carrier aggregation. Further, the first radio station (1) transmits, to the second radio station (2), update information regarding an update to a configuration related to the radio resource control for the second cell (20). It is thus, for example, possible to prevent or reduce data transmission/reception failures which would otherwise occur while a configuration of radio parameters or the like is being changed by a radio terminal in carrier aggregation of a plurality of cells served by different radio stations.

Abstract: A first base station (1) is configured to send, to a second base station (2), first configuration information that is necessary to establish a data bearer and a data radio bearer in the second base station (2) for a C/U-plane split scenario. Further, the first base station (1) is configured to send, to a third base station (3), configuration information (e.g., LPN information) regarding the data bearer established in the second base station (2) when a mobile station (4) moves from a first cell (10) to a third cell (30) (S103 and S104). It is thus, for example, possible to contribute to a reduction in wasted signaling when a UE moves between cells in the C/U-plane split scenario.

Abstract: Congestion determination means determines whether or not a road near an entrance of a first parking lot for which the vehicle is heading is congested based on sensor information output by a sensor. Selection means selects, from among one or more parking lots different from the first parking lot, a second parking lot to which the vehicle is to be guided when the congestion determination means determines that the road is congested. Notification means notifies the vehicle of the second parking lot.

Abstract: A transmission device is a transmission device that transmits communication data to one or more reception devices via a network. A transmission device includes: a specification unit that specifies a reception device number indicating the number of the reception devices that are a destination of communication data; a determination unit that, in a case where the reception device number is a first number, determines a data size or a bit rate of the communication data such that the data size or the bit rate becomes smaller or lower than that in a case where the reception device number is a second number smaller than the first number; a generation unit that generates the communication data by using the determined data size or bit rate; and a transmission unit that transmits the generated communication data to one or more reception devices that are the destination via the network.
