Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention to which the claims are made. Also, not all combinations of features described in the embodiments are essential to the means of solving the invention.

FIG. 1 schematically shows an example of the system 10. The system 10 may include a management device 100 that manages a plurality of mobile bodies 200. The system 10 may include a plurality of mobile bodies 200. The system 10 may include a location information recording server 400.

Each of the plurality of mobile bodies 200 may have a plurality of antennas arranged so as to have directivity in different directions. The antenna may be a beamforming antenna. The mobile body 200 may be capable of wireless communication in parallel with the plurality of other mobile bodies 200 by using each of the plurality of antennas. That is, the mobile body 200 may be capable of wireless communication at the same time as the plurality of other mobile bodies 200. FIG. 1 illustrates a case where the mobile body 200 has six antennas and is capable of wireless communication with another mobile body 200 in six directions. In FIG. 1, the illustration of the antenna is omitted.

The mobile body 200 may be a mobile body that moves in the sky. For example, the mobile body 200 may be an unmanned aerial vehicle such as a drone and a HAPS (High Altitude Platform Station). The mobile body 200 may be a mobile body that moves on land. For example, the moving body 200 may be a vehicle. The mobile body 200 may be a mobile body that moves on the water. For example, the moving body 200 may be a ship.

The plurality of mobile bodies 200 may form the mesh network 600 by, for example, arranging them along the directivity direction of the antenna and establishing a wireless communication connection with each other, as illustrated in FIG. Then, at least one mobile body 200 out of the plurality of mobile bodies 200 may establish a wireless communication connection with the gateway 300 and access the network 50 via the gateway 300. The gateway 300 may be wiredly connected to the network 50 via an optical fiber, a metal cable, or the like.

The network 50 may include the Internet. The network 50 may include a mobile communication network. The mobile communication network may conform to a 3G (3rd Generation) communication method. The mobile communication network may comply with the LTE (Long Term Evolution) communication method. The mobile communication network may also comply with the 5G (5th Generation) communication method. The mobile communication network may conform to the communication method after the 6G (6th Generation) communication method.

The plurality of mobile bodies 200 may function as radio base stations. The mobile body 200 may form a wireless communication area and provide a wireless communication service to a communication terminal in the wireless communication area. Examples of communication terminals include mobile phones such as smartphones, tablet terminals, PCs (Personal Computers), so-called IoT (Internet of Things) devices, and the like. In this way, the mesh network 600 may function as a backhaul.

The mobile body 200 may establish a wireless communication connection with the direct access terminal 60. The direct access terminal 60 may access the network 50 via the mesh network 600 by a wireless communication connection with the mobile body 200. The direct access terminal 60 may function as a radio base station.

Here, when a mesh network is configured by a plurality of wireless communication devices capable of wireless communication with each other, it is basically realized in a line-of-sight environment. Therefore, radio wave interference with the wireless communication device existing beyond the wireless communication device to be communicated may become a problem. For example, in a line-of-sight environment, the radio wave loss due to the path length is relatively small, so that the problem of radio wave interference may not be solved even if the distance between the wireless communication devices is increased. Further, for example, when a wireless communication device is mounted on a mobile body such as a drone, it is necessary to secure electric power for the mobile body to operate. Therefore, it is important to reduce the power consumption of the wireless communication device.

On the other hand, in the system 10 according to one embodiment, the management device 100 can reduce radio wave interference in the mesh network 600 by devising a method of thinning out communication paths between mobile bodies 200. Further, in the system 10 according to the embodiment, the mobile body 200 can reduce the power consumption. In one embodiment, the management device 100 may include an acquisition unit 102 and a control unit 104.

The acquisition unit 102 can acquire the position information of the plurality of moving bodies 200. The acquisition unit 102 may acquire the position information of the plurality of mobile bodies 200 from the position information recording server 400.

The position information recording server 400 may be connected to the network 50 to record and manage the position information of each mobile body 200. The location information recording server 400 may be arranged in the mobile communication network. The location information recording server 400 may be arranged in the core network, for example. The location information recording server 400 may be located on the Internet. The position information recording server 400 may receive each position information from each of the plurality of mobile bodies 200. The management device 100 and the location information recording server 400 may be integrated.

The control unit 104 may control each of the plurality of mobile bodies 200 so that a part of the antennas of the plurality of antennas is active and the other antennas of the plurality of antennas are inactive. The control unit 104 may activate a plurality of antennas corresponding to a plurality of directions for each of the plurality of mobile bodies 200 according to the position indicated by the position information acquired by the acquisition unit 102. As a result, the system 10 according to the embodiment can reduce the power consumption of the mobile body 200 as compared with the case where all of the plurality of antennas are activated.

The control unit 104 may, for example, have a plurality of beams for each of the plurality of mobile bodies 200 so as to prevent the beam output by each of the plurality of mobile bodies 200 from interfering with the communication of the adjacent mobile body 200. It may be controlled so that some of the antennas are active and the other antennas of the plurality of antennas are inactive. For example, the control unit 104 may generate a beam output by each of the plurality of mobile bodies 200 while maintaining a state in which each of the plurality of mobile bodies 200 has established a wireless communication connection with at least two mobile bodies 200. For each of the plurality of mobile bodies 200, one of the antennas of the plurality of antennas is activated, and the other of the plurality of antennas is activated so as to avoid interfering with the communication of the mobile body 200 of the preceding neighbor. The antenna may be controlled to be inactive. Specifically, the control unit 104 tells the first mobile body 200, for example, along the first direction in which the antenna of one of the first mobile bodies 200 has directivity among the plurality of mobile bodies 200. Controlled to deactivate the antenna having directivity in the direction facing the first direction among the plurality of antennas of the third moving body adjacent to the adjacent second moving body along the first direction. You can do it. As a result, the system 10 according to the embodiment can suppress radio wave interference with the communication of the mobile body 200 adjacent to the destination. That is, according to the system 10 according to the embodiment, the communication efficiency of the entire mesh network 600 can be improved.

Here, by thinning out the communication paths, the number of hops due to route detour may increase in some sections. On the other hand, the system 10 according to the embodiment may change the thinning pattern of the communication path by time division. For example, the control unit 104 may control each of the plurality of mobile bodies 200 to switch a plurality of antenna patterns having different active antennas among the plurality of antennas in a time division manner. The control unit 104 may, for example, cause each of the plurality of mobile bodies 200 to switch the antenna pattern in a time division so that the mesh network 600 different in time division is configured by the plurality of mobile bodies 200. Specifically, the control unit 104 may switch between the active antenna and the inactive antenna of each of the plurality of mobile bodies 200 so that the mobile body of the communication partner is switched by time division, for example. .. The control unit 104 may execute these controls while maintaining a state in which each of the plurality of mobile bodies 200 has established a wireless communication connection with at least two mobile bodies 200. According to this, the system 10 according to the embodiment can set the communication path of the shortest path in a time cycle. That is, according to the system 10 according to the embodiment, the user can use the communication path of the shortest path in a time cycle. That is, according to the system 10 according to the embodiment, the communication delay can be reduced.

FIG. 1 illustrates a case where the management device 100 is connected to the network 50, but the present invention is not limited to this. Any one of the plurality of mobile bodies 200 may be equipped with the management device 100.

FIG. 2 schematically shows an example of an antenna configuration of an unmanned aerial vehicle 500. The unmanned aerial vehicle 500 may be an example of the mobile body 200. The unmanned aerial vehicle 500 may have six antennas 502 arranged to have directivity in six directions and antennas 504 arranged to have directivity in the downward direction. As described above, the unmanned aerial vehicle 500 may have an antenna configuration in which all the directions in which the communication target may exist when viewed from the own aircraft are covered by any of the antennas having a multi-faceted configuration. Further, in the unmanned aerial vehicle 500, the coverage ranges of adjacent antennas may overlap. For example, in the unmanned aerial vehicle 500, the coverage range of the adjacent antennas may overlap with the adjacent antennas within the half width of the coverage range of the adjacent antennas. When the moving body 200 is a vehicle, a ship, or the like, the antenna may be arranged on the upper surface side instead of the lower surface side.

The antenna 504 may be used in part for forming a wireless communication area and in other parts for wireless communication with the direct access terminal 60. The antenna 504 may be used only for forming a wireless communication area. Further, the antenna 504 may be used only for wireless communication with the direct access terminal 60.

3 and 4 are explanatory views for explaining antenna control by the unmanned aerial vehicle 500. The beam range 508 indicates the range of beamforming of the beam 506.

In the system 10, it is desirable that the formation of the plurality of unmanned aerial vehicles 500 is not disturbed and the positional relationship does not change, but the positional relationship of the plurality of unmanned aerial vehicles 500 can be changed by various factors. The unmanned aerial vehicle 500 controls the unmanned aerial vehicle 500 of the communication partner to be tracked by beamforming when the positional relationship between the unmanned aerial vehicle 500 of the communication partner having established the wireless communication connection and the own aircraft changes. good. The unmanned aerial vehicle 500 may respond by beamforming when the unmanned aerial vehicle 500 of the communication partner is located in the direction within the beam range 508 of a certain antenna 502, and may respond by antenna switching when it is out of the beam range 508. According to this, the system 10 according to one embodiment can easily maintain a wireless communication connection. That is, according to the system 10 according to the embodiment, the communication efficiency of the entire mesh network 600 can be improved.

For example, the unmanned aerial vehicle 500 has a positional relationship between its own aircraft and the first unmanned aerial vehicle 500 while wirelessly communicating with the first unmanned aerial vehicle 500 by a beam from the first antenna 502 of the plurality of antennas 502. Will be described when is changed. The unmanned aerial vehicle 500 may, for example, use the first antenna 502 to track the first unmanned aerial vehicle 500 by beamforming when the first unmanned aerial vehicle 500 is located within the beam range 508 of the first antenna 502. You may control it. Further, the unmanned aerial vehicle 500 uses, for example, an antenna used for wireless communication with the first unmanned aerial vehicle 500 when the first unmanned aerial vehicle 500 is out of the beam range 508 of the first antenna 502. The plurality of antennas 502 may be controlled so as to switch from the antenna 502 to another antenna 502 among the plurality of antennas 502. In this way, the unmanned aerial vehicle 500 can cover all directions of the lower hemisphere by beamforming and antenna switching. When the unmanned aerial vehicle 500 tracks the first unmanned aerial vehicle 500 by beamforming, for example, the antenna 502 other than the first antenna 502 may also track the first unmanned aerial vehicle 500. Further, the unmanned aerial vehicle 500 may be switched to a plurality of other antennas 502, for example, when the antenna to be used is switched to another antenna 502. According to these, in one embodiment, the unmanned aerial vehicle 500 can maintain wireless communication with a moving object relatively easily.

5 to 10 schematically show an example of the mesh network 600. The active direction 510 indicates the directivity direction of the active antenna. FIG. 5 illustrates a situation in which all unmanned aerial vehicles 500 have antennas in six directions active. In this case, the mesh network 600 can ensure very high redundancy. On the other hand, in this case, there is a high possibility that a large amount of radio wave interference will occur in the mesh network 600. FIG. 6 illustrates a state in which the directions of communication paths are set at equal angles and thinned out from 6 directions to 3 directions. In this case, the mesh network 600 can reduce the occurrence of radio wave interference. In this case, in the mesh network 600, an unmanned aerial vehicle 500 that does not communicate is generated. The unmanned aerial vehicle 500 that does not communicate can reduce power consumption.

As illustrated in FIG. 7, the control unit 104 is in a state where each of the plurality of unmanned aerial vehicles 500 establishes a wireless communication connection with at least two unmanned aerial vehicles 500 based on the position information of the plurality of unmanned aerial vehicles 500. For each of the plurality of unmanned aerial vehicles 500, a plurality of antennas 502 so as to prevent the beam output by each of the plurality of unmanned aerial vehicles 500 from interfering with the communication of the adjacent unmanned aerial vehicle 500 while maintaining the above. You may control to activate some of the aircraft 502 and deactivate the other 502 of the plurality of aircraft 502.

As illustrated in FIG. 7, the control unit 104 activates three adjacent antennas 502 among the six antennas 502 and deactivates the other three antennas 502 according to the position indicated by the position information. The first pattern may be switched between the second pattern in which three antennas 502 of the six antennas that are not adjacent to each other are activated and the other three antennas 502 are inactive.

That is, the control unit 104 can reduce the interference in the mesh network 600 by controlling the active patterns of the antennas 502 of the plurality of unmanned aerial vehicles 500 that can construct the mesh network 600. Specifically, if the pattern is as illustrated in FIG. 7, the control unit 104 can avoid interference of a certain unmanned aerial vehicle 500 with the unmanned aerial vehicle 500 two ahead. That is, according to the system 10 according to the embodiment, the communication efficiency of the entire mesh network 600 can be improved.

The control unit 104 switches between an active antenna and an inactive antenna of each of the plurality of unmanned aerial vehicles 500 so that the mesh network 600 shown in FIGS. 7, 8 and 9 is configured by time division. You may let me. As a result, the control unit 104 switches the unmanned aerial vehicle 500 of the communication partner in a time division while maintaining the state in which each of the plurality of unmanned aerial vehicles 500 has established a wireless communication connection with at least two unmanned aerial vehicles 500. It is possible to switch between the active antenna and the inactive antenna of each of the plurality of unmanned aerial vehicles 500.

The control unit 104 may control the plurality of unmanned aerial vehicles 500 so as to construct different mesh networks 600 at predetermined time intervals. The control unit 104 may be switched, for example, every 1 / 3T. T may be any time. As a result, it is possible to realize communication in one hop in at least one division time in all communication paths.

The control unit 104 may adjust the timing of switching to a different mesh network 600. For example, the control unit 104 may control the switching timing so as to maintain a communication path with more communication traffic for a longer period of time. Thereby, the system 10 according to the embodiment can reduce the possibility that the communication speed of the user changes abruptly. That is, according to the system 10 according to the embodiment, the convenience of the mesh network 600 can be improved.

FIG. 10 schematically shows an example of a mesh network 610 and a mesh network 620. The control unit 104 may group a plurality of unmanned aerial vehicles 500 to form a plurality of mesh networks. In the example shown in FIG. 10, the control unit 104 may divide the plurality of unmanned aerial vehicles 500 into two groups, have one group construct the mesh network 610, and the other group construct the mesh network 620. Thereby, the system 10 according to the embodiment can reduce the radio wave interference between the unmanned aerial vehicles 500 and can construct the mesh network 600 without leaving the unmanned aerial vehicles 500. That is, according to the system 10 according to the embodiment, the operational efficiency of the unmanned aerial vehicle 500 can be improved.

The management device 100 may control at least one unmanned aerial vehicle 500 in the mesh network 610 to establish a wireless communication connection with the gateway 300. The management device 100 may control at least one unmanned aerial vehicle 500 in the mesh network 620 to establish a wireless communication connection with the gateway 300.
