[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that the following description and drawings have been omitted or simplified as appropriate for clarity of explanation. Furthermore, in the following drawings, the same elements are given the same reference numerals, and duplicate explanations are omitted as necessary. Furthermore, in this disclosure, unless otherwise specified, "at least one of A or B (A / B)" may mean any one of A or B, or both A and B. Similarly, when "at least one" is used with respect to three or more elements, it may mean any one of these elements, or any multiple elements (including all elements).

[0012] First Embodiment FIG. 1 is a block diagram showing an example of a control device in the first embodiment. The control device 10 shown in FIG. 1 controls a non-terrestrial network device (not shown). The control device 10 may be included in the non-terrestrial network device (not shown). Alternatively, the control device 10 may be a device separate from the non-terrestrial network device (not shown). In this case, the control device 10 may be connected to the non-terrestrial network device (not shown) by a wire, or may be disposed in a terrestrial or other non-terrestrial network device (not shown) and connected to the non-terrestrial network device (not shown) by wireless.

[0013] The non-terrestrial network device (not shown) is a device included in a non-terrestrial network (NTN), and is an aircraft that moves on a “predetermined orbit.” The non-terrestrial network device (not shown) may be, for example, a geostationary orbit satellite (GEO), a low earth orbit satellite (LEO), or a high altitude platform station (HAPS).

[0014] A non-terrestrial network device (not shown) has a battery and a solar power generation system, and charges the battery with power generated by the solar power generation system (hereinafter, this charging may be referred to as "solar charging"). Here, the trajectory of the non-terrestrial network device (not shown) includes, for example, positions corresponding to daytime, which are suitable for solar charging the battery or positions where solar charging is possible (hereinafter, these may be referred to as "suitable solar charging positions" or "solar charging possible positions"). Furthermore, the trajectory of the non-terrestrial network device (not shown) includes, for example, positions corresponding to night, which are not suitable for solar charging the battery or positions where solar charging is not possible (hereinafter, these may be referred to as "unsuitable solar charging positions" or "unsolar charging possible positions"). Therefore, the remaining power of the battery of the non-terrestrial network device (not shown) is an important parameter for stable control of the non-terrestrial network device (not shown).

[0015] In FIG. 1, the control device 10 includes an acquisition unit 11 and a control unit 12.

[0016] The acquisition unit 11 acquires the traffic volume and remaining power volume of a non-terrestrial network device (not shown). "Traffic volume" is the communication traffic volume of the non-terrestrial network device (not shown). Furthermore, "traffic volume" is, for example, the traffic volume expected while moving from the current location of the non-terrestrial network device (not shown) to the next "suitable solar charging location" (or "solar charging impossible location") when the current location of the non-terrestrial network device (not shown) is a "solar charging unsuitable location" (or "solar charging impossible location"). "Remaining power volume" is the amount of power remaining in the battery of the non-terrestrial network device (not shown).

[0017] The control unit 12 controls a non-terrestrial network device (not shown) based on the traffic volume and remaining power amount acquired by the acquisition unit 11. For example, the control unit 12 may control the power of a beam of the non-terrestrial network device (not shown) formed by beamforming, or may control the power and diameter of the beam. These will be described in detail in the fourth embodiment. Alternatively, for example, the control unit 12 may set the non-terrestrial network device (not shown) as either a priority use device or a non-priority use device. This will be described in detail in the fifth embodiment.

[0018] As described above, according to the first embodiment, the acquisition unit 11 in the control device 10 acquires the traffic volume and remaining power amount of a non-terrestrial network device (not shown). The control unit 12 controls the non-terrestrial network device (not shown) based on the traffic volume and remaining power amount acquired by the acquisition unit 11.

[0019] This configuration of the control device 10 makes it possible to control the non-terrestrial network device (not shown) based on the remaining battery power of the non-terrestrial network device (not shown), which is an important parameter for stably controlling the non-terrestrial network device (not shown). As a result, the non-terrestrial network device (not shown) can be operated stably.

[0020] Second Embodiment The second embodiment relates to a variation of the calculation of the traffic volume.

[0021] Fig. 2 is a block diagram showing an example of a control device according to the second embodiment. In Fig. 2, the control device 10 includes an acquisition unit 11 and a control unit 12. The acquisition unit 11 includes an acquisition unit 11A and a calculation unit 11B.

[0022] The acquisition unit 11A acquires the traffic volume of another non-terrestrial network device (not shown) located between the current position of the non-terrestrial network device (not shown) (the control target of interest) on the "predetermined orbit" and a solar charging position as the "expected traffic volume."

[0023] FIG. 3 is a diagram illustrating the acquisition of the expected traffic volume. In FIG. 3, non-terrestrial network device 20-1 is the non-terrestrial network device of interest and the target of control. Non-terrestrial network device 20-1 is located at position P11, which is its current position on the orbit. Non-terrestrial network devices 20-2 and 20-3 are located at positions P12 and P13 on the orbit, respectively. Positions P11, P12, and P13 are assumed to be "solar charging unsuitable positions" (or "solar charging impossible positions"). Position P14 shown in FIG. 3 is the position at which the "solar charging unsuitable position" (or "solar charging impossible position") switches to a "solar charging suitable position" (or "solar charging possible position"). In other words, position P14 shown in FIG. 3 is the next "solar charging suitable position" (or "solar charging possible position").

[0024] In this situation, the acquisition unit 11A acquires the current traffic volume of the non-terrestrial network devices 20-2 and 20-3 as the "expected traffic volume." That is, the non-terrestrial network device 20-1 moves along the trajectory so as to follow behind the non-terrestrial network devices 20-2 and 20-3. Therefore, the traffic volume of the non-terrestrial network devices 20-2 and 20-3 moving ahead can be regarded as the future traffic volume of the non-terrestrial network device 20-1.

[0025] Calculation unit 11B calculates the traffic volume to the "suitable solar charging position" (or "solar chargeable position") of non-terrestrial network device 20-1 (the control target of interest) based on the traffic volume of non-terrestrial network devices 20-2 and 20-3 acquired by acquisition unit 11A. For example, calculation unit 11B calculates the traffic volume to the "suitable solar charging position" (or "solar chargeable position") of non-terrestrial network device 20-1 by adding the current traffic volume of non-terrestrial network devices 20-2 and 20-3 acquired by acquisition unit 11A (i.e., the expected traffic volume of non-terrestrial network device 20-1).

[0026] As described above, according to the second embodiment, the acquisition unit 11A in the control device 10 acquires the current traffic volume of the non-terrestrial network devices 20-2 and 20-3. The calculation unit 11B calculates the traffic volume to the "solar charging suitable position" (or "solar charging possible position") of the non-terrestrial network device 20-1 based on the traffic volume of the non-terrestrial network devices 20-2 and 20-3 acquired by the acquisition unit 11A.

[0027] This configuration of the control device 10 makes it possible to accurately calculate the amount of traffic up to the "solar charging suitable position" (or "solar charging possible position") of the non-terrestrial network device 20-1 (the control target of interest).

[0028] <Third embodiment> The third embodiment relates to another variation of calculating the traffic volume.

[0029] Fig. 4 is a block diagram showing an example of a control device according to the third embodiment. In Fig. 4, the control device 10 includes an acquisition unit 11 and a control unit 12. The acquisition unit 11 includes an identification unit 11C, an output unit 11D, and a calculation unit 11E.

[0030] The identification unit 11C identifies multiple areas (hereinafter sometimes referred to as "passing areas") located under the trajectory between the current position P11 and position P14 of the non-terrestrial network device 20-1 and the scheduled time (hereinafter sometimes referred to as "scheduled passing time") that the non-terrestrial network device 20-1 will pass through each area.

[0031] The output unit 11D outputs "information on the expected traffic volume" corresponding to each combination of the passing area and the expected passage time identified by the identification unit 11C. For example, the output unit 11D has a "trained model." When this model receives a combination of the passing area and the expected passage time, it outputs "expected traffic volume" corresponding to this combination. Note that, for example, the combination of the area and the expected traffic volume acquired by the acquisition unit 11A of the second embodiment may be used to learn this model.

[0032] Calculation unit 11E calculates the traffic volume to the "suitable solar charging position" (or "solar chargeable position") of non-terrestrial network device 20-1 (the control target of interest) based on the multiple scheduled traffic volumes output from output unit 11D for multiple combinations of passing area and scheduled passing time. For example, calculation unit 11E calculates the traffic volume to the "suitable solar charging position" (or "solar chargeable position") of non-terrestrial network device 20-1 by adding up the multiple scheduled traffic volumes output from output unit 11D for multiple combinations of passing area and scheduled passing time.

[0033] As described above, according to the third embodiment, the output unit 11D in the control device 10 outputs the traffic volume corresponding to each combination of the passing area and scheduled passage time identified by the identification unit 11C. The calculation unit 11E calculates the traffic volume of the non-terrestrial network device 20-1 based on the multiple scheduled traffic volumes output by the output unit 11D for the multiple combinations of the passing area and scheduled passage time.

[0034] This configuration of the control device 10 makes it possible to accurately calculate the amount of traffic up to the "solar charging suitable position" (or "solar charging possible position") of the non-terrestrial network device 20-1 (the control target of interest).

[0035] <Fourth embodiment> The fourth embodiment relates to variations in control of non-terrestrial network devices. Note that the basic configuration of the control device of the fourth embodiment is the same as the control device 10 of the first embodiment, and therefore will be described with reference to FIG.

[0036] In the control device 10 of the fourth embodiment, the acquisition unit 11 acquires the traffic volume and remaining power volume of the non-terrestrial network device 20-1. The method for acquiring the traffic volume of the non-terrestrial network device 20-1 may be the method described in the second embodiment or the method described in the third embodiment. Furthermore, the method for acquiring information related to the remaining power volume of the battery of the non-terrestrial network device 20-1 is not particularly limited. For example, the acquisition unit 11 may receive a report of the remaining power volume from the non-terrestrial network device 20-1 at a predetermined interval.

[0037] In the control device 10 of the fourth embodiment, the control unit 12 controls the power of the beam of the non-terrestrial network device 20-1 based on the traffic volume and remaining power acquired by the acquisition unit 11. The non-terrestrial network device 20-1 has an array antenna including multiple antenna elements. The radiation direction of the transmission beam emitted from the non-terrestrial network device 20-1 can be controlled by controlling the phases of multiple signals radiated from the multiple active antenna elements. Furthermore, the power of the transmission beam emitted from the non-terrestrial network device 20-1 can be controlled by controlling the power of multiple signals radiated from the multiple antenna elements. That is, the control unit 12 generates a "power control signal" that controls the transmission power of each active antenna element based on the traffic volume and remaining power acquired by the acquisition unit 11. This power control signal is transmitted to the non-terrestrial network device 20-1. The control unit of the non-terrestrial network device 20-1 then receives this power control signal and controls the transmission power of each active antenna element based on this power control signal.

[0038] For example, the control unit 12 determines, from the remaining energy of the non-terrestrial network device 20-1, the amount of energy (hereinafter sometimes referred to as the "allowable energy") that can be used while the non-terrestrial network device 20-1 moves from its current position P11 to position P14, which is the next solar charging suitable position (or "solar charging possible position"). The "allowable energy" is equal to or less than the remaining energy. The control unit 12 then determines the transmission power of each antenna element to be used of the non-terrestrial network device 20-1 so that the power consumed for the traffic volume acquired by the acquisition unit 11 is equal to or less than the "allowable energy." Here, the unit of traffic volume may be, for example, bits (i.e., a unit representing the amount of information). The unit of energy may also be watt-hours. For example, the control unit 12 calculates the amount of energy allowed for unit traffic by dividing the "allowable energy" by the traffic volume. The control unit 12 may then identify the power of the array antenna corresponding to the amount of energy allowed for unit traffic using the correspondence relationship between the power of the array antenna and the amount of energy allowed for unit traffic. Then, the control unit 12 generates a "power control signal" including information indicating the transmission power of each antenna element to be used.

[0039] As described above, according to the fourth embodiment, the control unit 12 in the control device 10 controls the power of the beam of the non-terrestrial network device 20-1 based on the traffic volume and remaining power volume acquired by the acquisition unit 11.

[0040] This configuration of the control device 10 makes it possible to control the beam power of the non-terrestrial network device 20-1 based on the amount of traffic and remaining power until the next charging state is reached. This makes it possible to avoid a situation where the non-terrestrial network device 20-1 runs out of remaining power and is unable to communicate, thereby enabling the non-terrestrial network device to operate stably.

[0041] <Modification> The control unit 12 may control the power and diameter of the beam of the non-terrestrial network device 20-1 based on the traffic volume and remaining power volume acquired by the acquisition unit 11. For example, as described above, the control unit 12 calculates the power volume allowed for unit traffic by dividing the "allowable power volume" by the traffic volume. Then, the control unit 12 identifies the array antenna power corresponding to the power volume allowed for unit traffic using the correspondence relationship between the array antenna power and the power volume allowed for unit traffic. Then, based on the identified array antenna power, the control unit 12 identifies the number of usable antenna elements allowed for communication and the transmission power allowed for each usable antenna element. The beam diameter can be changed by changing the number of usable antenna elements. Here, the control unit 12 increases the number of usable antenna elements and reduces the transmission power allowed for each usable antenna element as the identified array antenna power decreases. This increases the antenna area of ​​the non-terrestrial network device 20-1 and improves the beam directionality, while keeping the power consumption of the array antenna within the power volume allowed for unit traffic.

[0042] Fifth Embodiment The fifth embodiment relates to an embodiment in which a non-terrestrial network device is set as a priority use device or a non-priority use device.

[0043] 5 is a block diagram showing an example of a control device according to the fifth embodiment. In FIG. 5, the control device 10 includes an acquisition unit 11 and a control unit 12.

[0044] In the control device 10 of the fifth embodiment, the acquisition unit 11 acquires the traffic volume and remaining power volume of the non-terrestrial network device 20-1. The method for acquiring the traffic volume of the non-terrestrial network device 20-1 may be the method described in the second embodiment or the method described in the third embodiment. Furthermore, the method for acquiring information related to the remaining power volume of the battery of the non-terrestrial network device 20-1 is not particularly limited. For example, the acquisition unit 11 may receive a report of the remaining power volume from the non-terrestrial network device 20-1 at a predetermined interval.

[0045] In the control device 10 of the fifth embodiment, the control unit 12 sets the non-terrestrial network device 20-1 as either a "priority use device" or a "non-priority use device" based on the traffic volume and remaining power amount acquired by the acquisition unit 11. A "priority use device" is a device that communicates preferentially with terrestrial terminals. A "non-priority use device" is a device that communicates with terrestrial terminals as a support for the "priority use device." The control unit 12 may perform control on the "non-priority use device," for example, by reducing the beam power described in the fourth embodiment, or by increasing the beam directivity and reducing the beam power.

[0046] For example, as shown in FIG. 5, the control unit 12 includes an electric energy calculation unit 12A, a setting unit 12B, and a control processing unit 12C.

[0047] The power amount calculation unit 12A calculates the "planned power consumption amount" to be used from the current position P11 to the next solar chargeable position P14, for example, by multiplying the traffic amount acquired by the acquisition unit 11 by the "unit power amount." The "unit power amount" is the amount of power consumed by unit traffic in the non-terrestrial network device.

[0048] The setting unit 12B sets the non-terrestrial network device 20-1 as either a prioritized use device or a non-priority use device based on the expected power consumption calculated by the power amount calculation unit 12A and the remaining power amount acquired by the acquisition unit 11. For example, the setting unit 12B determines the above-mentioned "allowable power usage." The "allowable power usage" may be, for example, 80% of the remaining power amount. Then, if the expected power consumption is equal to or less than the allowable power usage, the setting unit 12B sets the non-terrestrial network device 20-1 as a prioritized use device. On the other hand, if the expected power consumption is greater than the allowable power usage, the setting unit 12B sets the non-terrestrial network device 20-1 as a non-priority use device.

[0049] When the non-terrestrial network device 20-1 is set as a non-preferential use device, the control processing unit 12C may perform control such as reducing the beam power described in the fourth embodiment, or increasing the beam directivity and reducing the beam power, etc. Furthermore, when the non-terrestrial network device 20-1 is set as a preferential use device, the control processing unit 12C may control the non-terrestrial network device 20-1 to perform communication with a terminal that can no longer communicate with other non-terrestrial network devices that are set as non-preferential use devices.

[0050] The operation of the control device having the above configuration will be described. Fig. 6 is a flowchart showing an example of the processing operation of the control device in the fifth embodiment. Fig. 7 is a diagram explaining the processing operation of the control device in the fifth embodiment.

[0051] The acquisition unit 11 in the control device 10 acquires the traffic volume and remaining power of the non-terrestrial network device 20-1 (step S101). The method for acquiring the traffic volume of the non-terrestrial network device 20-1 may be the method described in the second embodiment or the method described in the third embodiment. Furthermore, the method for acquiring information related to the remaining power of the battery of the non-terrestrial network device 20-1 is not particularly limited. For example, the acquisition unit 11 may receive a report of the remaining power from the non-terrestrial network device 20-1 at a predetermined interval.

[0052] The power amount calculation unit 12A calculates the "planned power consumption" to be used from the current position P11 to the next solar chargeable position P14, for example, by multiplying the traffic amount acquired by the acquisition unit 11 by the "unit power amount" (step S102).

[0053] The setting unit 12B calculates the "allowable amount of power to be used" (step S103). The "allowable amount of power to be used" may be, for example, 80% of the remaining amount of power.

[0054] The setting unit 12B compares the "planned power consumption" with the "allowable power usage" (step S104), and if the "planned power consumption" is greater than the "allowable power usage" (step S104 NO), sets the non-terrestrial network device 20-1 as a non-priority use device (step S105).

[0055] The control processing unit 12C executes control for the non-terrestrial network device 20-1 to reduce the beam power or to increase the beam directivity and reduce the beam power (step S106). Fig. 7 shows a state after the control for increasing the beam directivity and reducing the beam power has been executed for the non-terrestrial network device 20-1.

[0056] If the "planned power consumption" is equal to or less than the "allowable power usage" (YES in step S104), the setting unit 12B sets the non-terrestrial network device 20-1 as the preferentially used device (step S107).

[0057] The control processing unit 12C controls the non-terrestrial network device 20-1 to execute (start) communication with some terminals that are communicating with other non-terrestrial network devices that have been set as non-preferential use devices (step S108). This allows the preferential use device to rescue the non-preferential use device that has limited power, thereby stabilizing communication in the non-terrestrial network. Figure 7 shows a situation in which the non-terrestrial network device 20-2 has been set as the preferential use device.

[0058] As described above, according to the fifth embodiment, the control unit 12 in the control device 10 sets the non-terrestrial network device as either a "priority use device" or a "non-priority use device" based on the traffic volume and remaining power volume acquired by the acquisition unit 11.

[0059] This configuration of the control device 10 makes it possible to control the power of the non-terrestrial network devices throughout the entire non-terrestrial network, thereby enabling the non-terrestrial network devices to operate stably.

[0060] <Other embodiments> FIG. 8 is a diagram illustrating an example of the hardware configuration of a control device. In FIG. 8, the control device 100 has a processor 101 and a memory 102. The processor 101 may be, for example, a microprocessor, a microprocessing unit (MPU), or a central processing unit (CPU). The processor 101 may include multiple processors. The memory 102 is configured by a combination of a volatile memory and a non-volatile memory. The memory 102 may include storage located away from the processor 101. In this case, the processor 101 may access the memory 102 via an I / O interface (not shown).

[0061] The control device 10 of the first to fifth embodiments may each have the hardware configuration shown in FIG. 8. The acquisition unit 11 and the control unit 12 of the control device 10 of the first to fifth embodiments may be realized by the processor 101 reading and executing a program stored in the memory 102. The program can be stored using various types of non-transitory computer-readable media and supplied to the control device 10. Examples of non-transitory computer-readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives) and magneto-optical recording media (e.g., magneto-optical disks). Further examples of non-transitory computer-readable media include CD-ROMs (Read Only Memory), CD-Rs, and CD-R / Ws. Further examples of non-transitory computer-readable media include semiconductor memories. Examples of semiconductor memories include mask ROMs, programmable ROMs (PROMs), erasable PROMs (EPROMs), flash ROMs, and random access memories (RAMs). The program may also be supplied to the control device 10 by various types of transitory computer-readable media. Examples of transitory computer-readable media include electrical signals, optical signals, and electromagnetic waves. The transitory computer-readable media can supply the program to the control device 10 via a wired communication path such as an electrical wire or optical fiber, or via a wireless communication path.
