A flight control apparatus that enables a flying object to safely pass another flying object includes a detection unit configured to detect, in a predetermined range from a flying object, another flying object. A specifying unit is configured to specify a moving direction of the detected other flying object. A judging unit is configured to judge, based on the specified moving direction, whether or not passing is possible. A determination unit is configured to determine, based on a relationship between the flying object and the other flying object, content of a passing operation to be performed with respect to the other flying object. A flight control unit is configured to, if it is judged that passing is possible, control flight of the flying object and perform the passing operation according to the determined content.

Flight control apparatus and flight control system

Flight control unit and flight unit start flight in accordance with a flight plan. Flight history acquisition unit acquires a flight history of drone. Flight plan acquisition unit acquires a flight plan for drone. Inspection timing determination unit calculates a difference between the acquired flight plan and the acquired flight history, and based on the difference, determines an inspection timing for drone. Inspection timing notification unit provides notification of the determined inspection timing.

Information-processing device and information-processing method for determining an inspection timing for an aerial vehicle

Flight cessation detection unit detects that drone has ceased flying at an unexpected site. Situation information acquisition unit acquires, as situation information indicating a situation related to retrieval of the drone, information on weather in an area in which the drone has flown. Retrieval procedure determination unit determines a retrieval procedure for the drone based on a situation indicated by the acquired situation information. Retrieval procedure determination unit, upon detecting a time period having specific weather based on the acquired information on weather, determines a retrieval procedure in which the time period is designated as a retrieval time.

Information-processing device and information-processing method

Flight type determination unit determines a flight type of drone on the basis of parameters obtained by flight schedule obtainment unit. The flight type includes a travel type, which uses a destination as a parameter, a touring type, which uses a range in space (a touring range) as a parameter, and a hovering type, which uses a position in space (a hovering position) as a parameter. Allocation rule storage unit stores allocation rules for flight airspace corresponding to each of the plurality of flight types. Flight airspace allocation unit allocates flight airspace to drone on the basis of allocation rules corresponding to the flight type of that drone as indicated by the parameters obtained for that drone.

Aircraft operation system

The location detection unit detects a destination location for delivery of an item by a drone. The release determination unit determines whether the drone transporting the item can release and place the item at the destination. Upon determination that the release and placement is not possible, a standby airspace determination unit determines a standby airspace within which the drone waits. The wait-time determination unit determines a wait-time for the drone in the determined standby airspace. The wait-time determination unit determines a wait-time by which the drone can arrive at a next destination by a scheduled arrival time following departure of the drone departs after standby. The standby instruction unit issues to the drone an instruction related to the standby.

Information processing apparatus

A flight control apparatus includes a detection unit that detects within a predetermined range of an air vehicle another air vehicle. A specifying unit specifies a type of the detected other air vehicle. A determining unit determines a possibility that the air vehicle and the other air vehicle will collide, based on an attribute relating to movement of the other air vehicle. When it is determined that a possibility of collision exists, a flight control unit controls the flight of the air vehicle according to the specified type of the other air vehicle to avoid collision with the other air vehicle.

An information apparatus includes a schedule obtainment unit that obtains flight schedule information transmitted from terminals. Allocation unit allocates an airspace and a permitted flight period to drone based on the obtained flight schedule information. If there is a predetermined commonality in the airspaces and the flight directions of multiple drones, allocation unit causes those multiple drones to share the airspace under the condition that formation flight in which distances therebetween are controlled is performed. Allocation unit determines an arrangement in which multiple drones are aligned in the order in which drones withdraw from formation flight as the arrangement of multiple drones during formation flight. Also, allocation unit determines an arrangement in which drone that does not include a formation flight function is in front and drone that includes formation flight function follows therebehind.

A flight control apparatus includes an acquisition unit that acquires a flight plan in which first flight conditions are described, and information that indicates a time limit set with respect to a position on a path along which an air vehicle is to fly. An arrival judging unit judges, based on the acquired information, whether or not the air vehicle has arrived at the position within the time limit. A condition determination unit determines a second flight condition if it is judged that the air vehicle has not arrived at the position within the time limit. A flight control unit controls flight of the air vehicle selectively adopts a first flight control method which follows the first flight conditions or a second flight control method which follows the second flight condition based on a result obtained by the arrival judging unit.

Allocation result accumulation unit accumulates allocation results of each business operator that requests allocation of flight airspace of drone. Allocation result accumulation unit accumulates, as the allocation results, an allocated airspace amount represented by the size of allocated flight airspace and the period in which flight in the flight airspace is permitted. When allocation requests are received from multiple business operators, flight airspace allocation unit allocates flight airspace by giving priority to a high priority business operator according to the allocation results accumulated in allocation result accumulation unit with respect to each business operator. Flight airspace allocation unit allocates the flight airspace by assigning a higher priority to a business operator for which the allocated airspace amount that has been accumulated is small.

A mobile station includes a measurement unit that measures radio qualities for a serving cell and a candidate switching target cell; a cell switching determination unit that determines whether the radio quality of the serving cell is less than a reference quality corresponded in advance with a predetermined throughput, wherein, when the radio quality of the serving cell is less than the reference quality, the cell switching determination unit determines whether the serving cell is to be switched to the candidate switching target cell by comparing the radio quality of the serving cell with that of the candidate switching target cell; and a radio communication unit that transmits a signal for requesting the switching of the serving cell, and that receives a signal for instructing the switching of the serving cell from a network apparatus.

Mobile station and method for mobile communication system

In a parameter storage device, an offset value corresponding to a moving state (moving speed) and a serving frequency are stored. A parameter identifier reads from the parameter storage device an offset value corresponding to a serving frequency and a moving state. A measuring unit measures a radio communication quality of an inter-frequency cell. A measurement controller adds the offset value to the radio communication quality, to generate control information. The control information is transmitted via a transmitter to a network.

Mobile station, network, and handover control method

A mobile terminal used in a cellular mobile communication system is disclosed. The mobile terminal includes a measuring unit configured to measure reception levels of received signals; an averaging unit configured to average the measured reception levels based on a forgetting factor; a cell reselection unit configured to reselect a cell based on the averaged reception level; and a factor determining unit configured to determine the forgetting factor according to parameters sent from a network.

Mobile terminal and method used in the same

A communication method for continuously receiving multiple pieces of data from a radio base station via a radio link. The method includes determining whether or not any one of the multiple pieces of data is lost; and making an instruction to the radio base station to increase the transmission power of the radio base station when it is determined that any one of the multiple pieces of data is lost, the instruction being made before a retransmission timing when the transmitter retransmits the lost data piece.
