In Release 15 of 3GPP (3rd Generation Partnership Project), international standard specifications for wireless communication of drones flying in the sky were established in order to suppress signal interference caused by wireless communication by drones flying in the sky. Ta. However, constructing a new network (Network; NW) that conforms to the above-mentioned international standard specifications requires a large amount of cost. In the system 10 according to the present embodiment, for example, the drone determines the maximum transmission power based on a pattern table indicating the correspondence between flight altitude and maximum transmission power, and controls the transmission power based on the determined maximum transmission power. do. This makes it possible to suppress signal interference caused by wireless communications by drones flying above at a low cost.

Hereinafter, the present invention will be explained through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. Furthermore, not all combinations of features described in the embodiments are essential to the solution of the invention.

FIG. 1 schematically depicts an example of a system 10. The system 10 may include an aircraft 100 and an information processing device 200.

The flying object 100 is equipped with a control device 150 and a battery (not shown). The flying object 100 may fly using electric power stored in a battery.

The flying object 100 is, for example, an unmanned aircraft. The flying object 100 is, for example, a drone. The flying vehicle may be a manned aircraft. In FIG. 1, an example in which the flying object 100 is a drone will mainly be described.

Control device 150 controls the functions of flying object 100. For example, the control device 150 controls communication functions of the flying object 100. The aircraft 100 may communicate under the control of the control device 150.

The control device 150 controls the aircraft 100 to communicate wirelessly with the serving base station 40, for example. The serving base station 40 is a base station with which the aircraft 100 communicates. Controller 150 may control aircraft 100 to access network 20 via a wireless communication connection with serving base station 40 .

Network 20 includes, for example, a core network provided by a carrier. The core network complies with, for example, the LTE (Long Term Evolution) communication system. The core network may be compliant with a 5G (5th Generation) communication system. The core network may be compliant with a 6G (6th Generation) communication system or later aircraft communication system. The core network may conform to a 3G (3rd Generation) communication system. Network 20 may include the Internet.

For example, the control device 150 controls the flying object 100 to transmit a wireless signal using an antenna mounted on the flying object 100. The flying object 100 transmits a wireless signal by, for example, using the antenna to output radio waves that carry the wireless signal.

The flying object 100 may receive radio signals using an antenna mounted on the flying object 100. For example, the flying object 100 uses an antenna mounted on the flying object 100 to receive a radio signal carried by a radio wave output by an antenna 45 installed at the serving base station 40. The aircraft 100 may use the antenna to receive a radio signal carried by a radio wave output by an antenna 65 installed at an adjacent base station 60 that is a base station different from the serving base station 40. .

The antenna mounted on the flying object 100 is, for example, an omnidirectional antenna. The omnidirectional antenna may be a so-called omni antenna. The antenna mounted on the flying object 100 may be a directional antenna.

Control device 150 may control flight functions of aircraft 100. The flying object 100 may fly under the control of the control device 150.

The control device 150 controls the flight of the flying object 100 based on a flight control signal that controls the flight of the flying object 100, for example. The control device 150 controls the flight of the flying object 100 based on a flight control signal received via the network 20 from a flying object management device that manages the flying object 100, for example. The control device 150 may generate a flight control signal and control the flight of the aircraft 100 based on the generated flight control signal. In this case, the flying object 100 may be an autonomous flying object that flies autonomously.

For example, the aircraft 100 has a function of specifying its own flight altitude. The aircraft 100 uses, for example, an altimeter to identify the flight altitude at which it is flying.

For example, the flying object 100 has a function of specifying its own flight position. The aircraft 100 uses, for example, a GNSS (Global Navigation Satellite System) function to identify the flight position where the aircraft is flying. The aircraft 100 uses, for example, a GPS (Global Positioning System) function to identify the flight position where the aircraft is flying. The aircraft 100 may use an RTK (Real Time Kinematic) function to identify the flight position where it is flying.

The flight position of the aircraft 100 includes, for example, the latitude of the aircraft 100. The flight position of the aircraft 100 includes, for example, the longitude of the aircraft 100. The flight position of the aircraft 100 may include the flight altitude of the aircraft 100.

For example, the flying object 100 has a function of identifying the received signal quality of a received radio signal. For example, the aircraft 100 identifies the received signal quality of the wireless signal transmitted by the serving base station 40. Aircraft 100 may determine the received signal quality of wireless signals transmitted by neighboring base stations 60.

The radio signal is, for example, a reference signal (RS). The wireless signal may be any other signal.

The received signal quality includes, for example, received signal strength (RSS) indicating the strength of the received signal. The received signal quality includes, for example, Reference Signal Received Power (RSRP) indicating the received power of the reference signal. The received signal quality includes reference signal received quality (RSRQ) that indicates the reception quality of the reference signal. Received signal quality includes, for example, signal-to-noise ratio (SNR), which is the ratio of signal power to noise power. Received signal quality may include, for example, the Signal-to-Interference-plus-Noise Ratio (SNIR), which is the ratio of signal power to the sum of noise power and interference power.

Aircraft 100 may have other arbitrary functions. For example, the flying object 100 has a function of specifying its own flight speed. For example, the flying object 100 has a function of specifying the flight direction of its own aircraft. For example, the flying object 100 may have a function of specifying its own flight attitude. The aircraft 100 may have a function of capturing an image of the surroundings of the aircraft using an imaging device mounted on the aircraft.

For example, the control device 150 controls the transmission power with which the flying object 100 transmits a wireless signal. For example, the control device 150 stores in advance correspondence information indicating the correspondence between the flight altitude and the maximum transmission power at which the flying object 100 transmits a wireless signal. For example, the correspondence information may associate a flight altitude that is lower than the installation height of the base station antenna with the first maximum transmission power, and a flight altitude that is higher than the installation height of the base station antenna and the first maximum transmission power that is lower than the first maximum transmission power. 2 maximum transmission power. The control device 150 identifies the flight altitude at which the aircraft 100 is flying, and transmits the information based on the maximum transmission power of the correspondence information of the aircraft 100 that is stored in association with the identified flight altitude of the aircraft 100. , controls the transmission power of the aircraft 100. For example, when the flight altitude of the identified flying object 100 is lower than the installation height of the antenna of the base station, the control device 150 controls the transmission power of the flying object 100 based on the first maximum transmission power. For example, when the flight altitude of the identified flying object 100 is higher than the installation height of the antenna of the base station, the control device 150 controls the transmission power of the flying object 100 based on the second maximum transmission power.

The information processing device 200 generates correspondence information of the aircraft 100. The information processing device 200 may, for example, determine the output intensity of the radio waves output by the aircraft 100, the flight altitude of the aircraft 100 when the aircraft 100 outputs the radio waves, and the reception at which the serving base station 40 receives the radio waves. Correspondence information of the aircraft 100 is generated based on the intensity and the reception intensity at which the adjacent base station 60 receives the radio wave.

The information processing device 200 transmits the generated correspondence relationship information of the aircraft 100 to the aircraft 100, for example, via the network 20. The control device 150 may control the transmission power with which the flying object 100 transmits a wireless signal based on the correspondence information of the flying object 100 that the flying object 100 receives from the information processing device 200.

The information processing device 200 is placed on the ground, for example. The information processing device 200 may be mounted on the aircraft 100. In this case, the control device 150 and the information processing device 200 may be integrated. The control device 150 and the information processing device 200 may be different devices.

In recent years, mobile communication networks with a wider coverage area than wireless LANs (Local Area Networks) have been used to control aircraft flying over the sky, and to control the imaging devices installed on the aircraft. There is a growing need for transmitting images captured by. However, when an aircraft flying in the sky uses a mobile communication network, the radio signals transmitted by the aircraft flying in the sky and the radio signals transmitted by base stations installed on the ground or communication terminals on the ground. Signal interference may occur between the The propagation path of wireless signals transmitted by aircraft flying in the sky has fewer obstacles that can obstruct the wireless signals compared to the propagation path of wireless signals transmitted by base stations installed on the ground or communication terminals on the ground. Therefore, radio signals transmitted by aircraft flying over the sky may adversely affect communication conditions in a wide communication area included in a mobile communication network.

Therefore, in Release 15 of 3GPP, international standard specifications regarding wireless communication of aircraft flying in the sky were established in order to suppress the above-mentioned signal interference. However, current mobile communication networks are constructed on the premise of wireless communication between terrestrial communication terminals and base stations installed on the ground. Therefore, in order to realize a mobile communication network that complies with the international standard specifications established in 3GPP Release 15, it is necessary to construct a new mobile communication network that takes into consideration the aircraft flying above. . Building a new mobile communication network requires a large amount of cost. In view of the above, it is desirable to be able to reduce signal interference caused by radio signals transmitted by aircraft flying in the sky at low cost.

On the other hand, according to the system 10 according to the present embodiment, the control device 150 specifies the flight altitude at which the aircraft 100 is flying, and stores information in association with the identified flight altitude of the aircraft 100. The transmission power at which the aircraft 100 transmits a wireless signal is controlled based on the maximum transmission power of the correspondence relationship information of the aircraft 100 that is in use. The control device 150 can simply specify the flight altitude of the flight object 100 by storing in advance correspondence relationship information indicating the correspondence relationship between the flight altitude and the maximum transmission power at which the flight object 100 transmits a wireless signal. , the maximum transmission power at which the aircraft 100 transmits a wireless signal can be determined, and the transmission power at which the aircraft 100 transmits a wireless signal can be appropriately controlled. Therefore, without constructing a new mobile communication network that takes into consideration drones flying in the sky, it is possible to use the current mobile communication network to transmit signals caused by wireless signals transmitted by aircraft flying in the sky. Interference can be suppressed. Thereby, the system 10 according to the present embodiment can suppress signal interference caused by radio signals transmitted by aircraft flying in the sky at low cost.

FIG. 2 is an explanatory diagram for explaining an example in which the control device 150 controls the transmission power of the flying object 100. FIG. 2 mainly shows an example in which the control device 150 controls the transmission power of the aircraft 100 by comparing the flight altitude of the aircraft 100 with a predetermined flight altitude threshold included in the correspondence information. explain.

The flight altitude threshold is determined, for example, based on the installation height of the base station antenna. The installation height of the base station antenna is, for example, the altitude above the ground where the base station is installed. The installation height of the base station antenna may be an absolute altitude. In FIG. 2, the explanation will be continued assuming that the installation height of the antenna of the base station is the height above the ground from the ground surface where the base station is installed.

The flight altitude threshold is determined, for example, based on the installation height of each antenna of a plurality of base stations. The flight altitude threshold is determined, for example, based on an average installation height that is the average of the installation heights of the respective antennas of a plurality of base stations. The flight altitude threshold may be determined, for example, based on the antenna installation height corresponding to the median installation height of each antenna of a plurality of base stations. The plurality of base stations are, for example, base stations installed within the same flight area. In FIG. 2, the average installation height of the serving base station 40 and the adjacent base station 60 is _h0 , and the first flight altitude threshold is the installation height of the antenna 45 of the serving base station 40 and the installation height of the antenna 65 of the adjacent base station 60. The explanation will be continued assuming that the installation height is 1/2 h _m , which is half of the average installation height h _m , and that the second flight altitude threshold is h _m .

For example, the control device 150 determines that the flight altitude of the aircraft 100 is equal to or higher than the average (=h ₀ ) of the installation heights of the serving base station 40 and the adjacent base station 60, and that the first flight altitude threshold (=1/ 2h _m ), the transmission power of the aircraft 100 is controlled based on the first maximum transmission power. The first maximum transmission power is, for example, 23 dBm. For example, when the flight altitude of the flying object 100 is equal to or higher than the first flight altitude threshold and lower than the second flight altitude threshold (=h _m ), the control device 150 controls the second maximum transmission power to be lower than the first maximum transmission power. The transmission power of the flying object 100 is controlled based on the maximum transmission power. The second maximum transmission power is, for example, 20 dBm. For example, when the flight altitude of the flight object 100 is equal to or higher than the second flight altitude threshold, the control device 150 controls the transmission power of the flight object 100 based on a third maximum transmission power that is smaller than the second maximum transmission power. . The third maximum transmission power is, for example, 14 dBm.

FIG. 3 schematically shows an example of the control device 150. Control device 150 has memory 152, altimeter 154, CPU 156, and chipset 158. Note that it is not necessarily necessary for the control device 150 to have all of these configurations.

Memory 152 stores correspondence information. The memory 152 stores, for example, correspondence information received from the information processing device 200. The memory 152 may store correspondence information acquired by receiving input from a user of the flying object 100 using an input device included in the control device 150.

The memory 152 stores, for example, correspondence information of a software embedding method. The memory 152 may also store correspondence information in any other format.

The memory 152 stores correspondence information in the form of a pattern table, for example. Memory 152 may also store any other form of relationship information. FIG. 3 mainly describes an example in which the memory 152 stores correspondence information 180 in the form of a pattern table, which is used by the control device 150 in the example of FIG. 2 to determine the maximum transmission power. .

Memory 152 stores software, for example. Memory 152 stores software that determines the maximum transmission power of aircraft 100 based on the flight altitude of aircraft 100 and correspondence information, for example. Memory 152 may also store any other software.

Altimeter 154 identifies the flight altitude of aircraft 100. The altimeter 154 is, for example, a radio altimeter that can measure the altitude of the flying object 100 above the ground. The altimeter 154 may be a barometric altimeter that can measure the absolute altitude of the flying object 100.

For example, when the flight path of the aircraft 100 includes both areas with low absolute altitudes such as flat areas and areas with high absolute altitudes such as mountainous areas, the installation height of the antenna of the base station in the area with low absolute altitudes may be The altitude difference between the absolute altitude and the absolute altitude of the installation height of the antenna of the base station in the high absolute altitude area is significantly large. On the other hand, the difference in altitude between the height above the ground of the installation height of the antenna of a base station in an area with low absolute altitude and the height above the ground of the installation height of the antenna of a base station in an area with high absolute altitude is relatively small. Therefore, in order for the control device 150 to appropriately determine the maximum transmission power of the flight object 100 regardless of the flight path of the flight object 100, the altimeter 154 is a radio altimeter, and the control device 150 has to adjust the altitude of the flight object 100 from the ground. It is desirable to determine the maximum transmit power of the aircraft 100 based on the following.

CPU 156 determines the maximum transmission power of aircraft 100. CPU 156 determines the maximum transmit power of aircraft 100, for example, by executing software stored in memory 152. For example, the CPU 156 determines the maximum transmission power at which the aircraft 100 transmits a wireless signal based on the correspondence information 180 stored in the memory 152 and the flight altitude of the aircraft 100 specified by the altimeter 154. .

Chipset 158 determines the transmit power at which aircraft 100 transmits wireless signals. Chipset 158 determines the transmission power of aircraft 100 based on the maximum transmission power of aircraft 100 determined by CPU 156, for example. Chipset 158 may control an antenna mounted on aircraft 100 to transmit a wireless signal with the determined transmission power.

Chipset 158 may determine the received signal quality of the wireless signals received by aircraft 100. CPU 156 may determine the maximum transmission power at which aircraft 100 transmits a wireless signal, further based on the received signal quality of the wireless signal received by aircraft 100, which is specified by chipset 158.
