Abstract: In order to connect a radio terminal in a heterogeneous network environment to a connection destination in an appropriate frequency band, a management device comprises: a located-area information acquisition unit that acquires located-area information of the radio terminal; a first base station identification unit that uses the located-area information to identify a first base station forming a macrocell; a second base station identification unit that uses the located-area information to perform a first assessment for assessing whether or not the radio terminal is within one of the small cells, and that, when the radio terminal is within one of the small cells, identifies a second base station forming the small cell; a high-speed communication requirement assessment unit that performs a second assessment for assessing whether or not the radio terminal requires high-speed communication based on at least a predicted traffic demand volume from the radio terminal; a session setting determination unit that determi

Abstract: An objective is to provide a management apparatus, a management method, and a management program that can eliminate interference without involving complicated control between cells. If interference is occurring between a first RU (Radio Unit) connected to a first virtualized DU (vDU: virtualized Distributed Unit) and a second RU connected to a second vDU different from the first vDU, a connection destination determination unit (120) determines a connection destination vDU to which the first RU and the second RU are to be connected, so that the first RU and the second RU in which the interference is occurring are connected to the same vDU. A control unit (130) implements control such that the first RU and the second RU in which the interference is occurring are connected to the connection destination vDU.

Abstract: A management apparatus in a radio access network including RUs (Radio Units) and vDUs (virtual Distributed Units), the management apparatus comprising: a monitoring unit configured to acquire load states of the respective vDUs; and a control unit configured to determine, among the vDUs, based on the load states that have been acquired, a first vDU in which a load should be lowered and a second vDU for receiving part of the load from the first vDU, to determine, among RUs connected to the first vDU, an RU for which a connection destination is to be changed to the second vDU, and to change the connection destination of the determined RU from the first vDU to the second vDU.

Abstract: An objective is to suppress degradation of the usability of radio terminals even in cases in which the modes of use of the radio terminals fluctuate. A placement change determiner (510) determines, based on information associated with conditions or future conditions estimated from the conditions in a service area to which one or more RUs (Radio Units) in a mobile communication system belong, a placement change regarding at least one NF (Network Function) among NFs in the mobile communication system. A placement destination determiner (520) determines, based on the information, an NF to be changed and a placement destination of the NF to be changed. A deployer (530) executes the placement change by instantiating the NF to be changed at the placement destination.

Abstract: A transmit/receive module includes plural duplexers, a power amplifier, and a sending transmission line. The plural duplexers operate in bands different from each other and each includes a transmit filter and a receive filter. The power amplifier amplifies signals of pass bands of the plural transmit filters and outputs the amplified signals. The sending transmission line is connected to the plural transmit filters. The signals of the pass bands of the plural transmit filters output from the power amplifier are transmitted through the sending transmission line.

Abstract: A lighting system includes a plurality of lighting devices and a control device. The plurality of lighting devices are installed in a facility. The control device controls the plurality of lighting devices. The control device controls lighting light projected by at least one lighting device, belonging to the plurality of lighting devices, into colored lighting light, of which a color is different from a color white, to give, upon acquiring information about an event in question, a sign depending on the event in question.

Abstract: A display device includes: a display panel including a sensor unit configured to detect a touch operation; a first control unit configured to supply a first signal to the display panel; and a second control unit configured to calculate touch information related to the touch operation and to supply the touch information to the first control unit. The first control unit includes: a signal generator configured to generate the first signal based on an image signal supplied from an external image signal supply source; and an overdrive circuit configured to perform a process of increasing an amplitude of the first signal generated by the signal generator. The overdrive circuit is actuated based on the touch information from the second control unit. The first control unit, in response to the actuation of the overdrive circuit, supplies the first signal having the amplitude increased by the overdrive circuit to the display panel.

Abstract: A fuel supply system for an internal combustion engine includes a heat exchanger that has a heat exchanging wall between a liquefied fuel passage and an engine coolant passage. Heated and vaporized fuel flowing out from the liquefied fuel passage of the heat exchanger is supplied to the internal combustion engine. A flow rate of liquefied fuel supplied to the liquefied fuel passage of the heat exchanger is set. A flow rate of engine coolant supplied to the engine coolant passage of the heat exchanger is determined on the basis of a temperature of the engine coolant supplied to the engine coolant passage of the heat exchanger such that nucleate boiling or transition boiling of the liquefied fuel in the set flow rate occurs near a boundary between nucleate boiling and transition boiling in the liquefied fuel passage.
