  FIG. 2 is a block diagram illustrating a configuration example of the base station apparatus 200 of the fixed base station 20 according to the present embodiment. In FIG. 2, the base station device 200 of the fixed base station 20 includes a control unit 201, a wireless communication unit 202 that performs wireless communication with the user device 50 via the antenna 250, and a storage unit 203. The antenna 250 is a Massive MIMO (Multiple-Input and Multiple-Output) antenna having a plurality of antenna elements and having a beam forming function capable of controlling the number and direction of antenna beams. Note that the fixed base station 20 may be a macro cell base station or a small cell base station that forms a small cell by narrowing a beam with respect to a road 70 as a moving route located in the macro cell. .

  The Massive MIMO antenna is an antenna that has, for example, a maximum of 128 antennas and allocates dedicated radio waves for each user using techniques such as beam forming and spatial multiplexing. A conventional antenna shares a frequency among a plurality of users, whereas a massive MIMO antenna occupies a dedicated frequency for each user. In the present embodiment, a Massive MIMO antenna is used as the antenna 250, and the cell 20A is formed by narrowing the beam with respect to the road 70 that is the moving path of the automobile 40 by beam forming.

  In FIG. 1, antennas 250 (1) to 250 (4) of fixed base stations 20 (1) to 20 (4) respectively transmit radio waves toward a moving path along which automobiles 40 (1) to 40 (4) travel. Cells 20A (1) to 20A (4) that are installed to transmit and receive and extend in the longitudinal direction of the movement path are formed. That is, the cells 20 </ b> A (1) to 20 </ b> A (4) are formed so as to extend along the road 70. These cells 20 </ b> A (1) to 20 </ b> A (4) may be long oval or oval extending in the longitudinal direction of the movement path of the automobiles 40 (1) to 40 (4). Each of the elliptical or oval cells 20A (1) to 20A (4) has, for example, a short diameter of 10 m, may be 5 m or more and 50 m or less, has a long diameter of 100 m, and is 50 m or more and 1 Km or less. May be.

  In FIG. 1, a user having user devices 50 (1) to 50 (4) rides on cells 20 </ b> A (1) to 20 </ b> A (4) formed on a road 70 adjacent to a building 71 such as a building. Four automobiles 40 (1) to 40 (4) to be entered are respectively included. For example, the automobile 40 (1) running in the upper lane is in the cell 20A (1), and the user device 50 (1) can wirelessly communicate with the fixed base station 20 (1). In addition, since the automobile 40 (2) travels in the cell 20A (1) and enters the overlapping area with the cell 20A (2), the user apparatus 50 (2) wirelessly communicates with the fixed base station 20 (1). A handover process can be performed from communication to wireless communication with the fixed base station 20 (2) having high radio field intensity. On the other hand, the automobile 40 (3) running on the lower opposite lane is in the cell 20A (3), and the user device 50 (3) can wirelessly communicate with the fixed base station 20 (3). In addition, since the automobile 40 (4) travels in the cell 20A (3) and enters the overlapping area with the cell 20A (4), the user apparatus 50 (4) wirelessly communicates with the fixed base station 20 (3). It is possible to perform handover processing from communication to wireless communication with the fixed base station 20 (4) having high radio field intensity.

  As shown in FIG. 1, even in an area where communication traffic increases due to concentration of user devices 50 such as a travel route of a car 40, the beam is extended so as to extend along an area such as the travel path of the car 40. A high communication quality can be maintained by forming the cell 20A by narrowing down.

  In addition, since the beam forming the cell 20A is formed along the moving direction in the moving path of the automobile 40, the direction of the cell forming beam and the moving direction of the automobile 40 are substantially parallel. Accordingly, even when an omni antenna is used as an antenna of a wireless communication device when the wireless communication device is mounted on the vehicle (mobile body) 40 and Doppler diversity is used to improve communication quality associated with the movement of the vehicle 40, Since the Doppler frequency shift in the reception signal of the wireless communication generated with the movement of the automobile (mobile body) 40 equipped with the communication device can be concentrated around the maximum Doppler frequency, the decrease in the throughput of the wireless communication is suppressed. be able to.

  FIG. 3 is an explanatory diagram illustrating another example of the communication system according to the embodiment of the present invention. In FIG. 3, each of the fixed base stations 20 (1) and 20 (2) is provided with two Massive MIMO antennas. The fixed base station 20 (1) is provided with antennas 250 (1) and 250 (2). The cell 20A (1) is formed by the antenna 250 (1), and the cell 20A ( 2) is formed. The fixed base station 20 (2) is provided with antennas 250 (3) and 250 (4). The cell 20A (3) is formed by the antenna 250 (3), and the cell is formed by the antenna 250 (4). 20A (4) is formed. Thereby, since a plurality of cells 20A can be formed by one fixed base station 20, the number of fixed base stations 20 can be reduced compared to the configuration described with reference to FIG. Can be achieved.

  FIG. 4 is an explanatory diagram showing still another example of the communication system according to the embodiment of the present invention. In FIG. 4, the fixed base stations 20 (1) and 20 (2) set the lengths of the short axis directions of the cells 20 A (1) and 20 A (2) to about the width of the road 70, respectively. The moving automobile 40 is covered. For example, a cell 20A (1) is formed by the antenna 250 (1) of the fixed base station 20 (1), and automobiles 40 (1), 40 (4) moving in opposite directions located in the cell 20A (1). ) It is possible to communicate with the respective user devices 50 (1) and 50 (4). Further, the cell 20A (2) is formed by the antenna 250 (2) of the fixed base station 20 (2), and the automobiles 40 (2), 40 (3) moving in opposite directions located in the cell 20A (2). ) It is possible to communicate with the respective user devices 50 (2) and 50 (3). Thus, by increasing the size of the cell 20A formed by the fixed base station 20 as compared with the configuration described with reference to FIG. 1, the number of fixed base stations 20 can be reduced, and the cost of installing the fixed base station 20 can be reduced. It is possible to go down.

A mobile base station may be mounted on the automobile 40 which is a moving body.
FIG. 5 is a front view of an automobile 40 equipped with a mobile base station (hereinafter referred to as “moving cell base station”) 30. In FIG. 5, a moving cell base station 30 forms a mobile cell (hereinafter referred to as “moving cell”) 30A that covers at least an outer peripheral area of the automobile 40 and the interior of the automobile 40, and the inside of the moving cell 30A. Relays communication between the user apparatus 50 located in the base station 20 and the fixed base station 20, a user apparatus existing in the cell 20A covered by the fixed base station 20 or another base station installed in another mobile unit . The moving cell 30 </ b> A may include a peripheral area outside the automobile 40 and an inner area of the automobile 40. The cell diameter of the moving cell 30A is, for example, 100 m, and may be 20 m or less to 50 m or less.

  The moving cell base station 30 includes a first antenna 350 for performing wireless communication between the base station device 300 and another moving cell base station 30 installed in the fixed base station 20 or another moving body, The moving cell 30A formed by the station device 300 includes a second antenna 370 that performs wireless communication with the user device 50 used by a general user of mobile communication. The first antenna 350 and the second antenna 370 are provided on the main body of the automobile 40, for example, a flat surface portion of the roof, a shark antenna portion at the rear of the roof in which an antenna for other uses is incorporated, or a pillar portion. The first antenna 350 and the second antenna 370 may be a shared antenna. Further, the first antenna 350 may include a plurality of antenna elements, and may have a beam forming function that can track the fixed base station 20 by controlling the number and direction of antenna beams. The second antenna 370 may include a plurality of antenna elements and have a beam forming function capable of controlling the number and direction of antenna beams.

  In FIG. 5, for convenience of illustration, the base station apparatus 300 is illustrated on the roof of the automobile 40, but for example, the base station apparatus 300 is located in the trunk of the automobile 40, the interior of the dashboard, the lower side of the seat. Etc. The base station apparatus 300 may include a power source (battery) in its own apparatus, but may receive power from a battery on the automobile 40 side. When power is supplied from the battery on the automobile 40 side, the power supply from the battery to the base station apparatus 300 is a predetermined time (for example, 1 hour) from the stop of driving (OFF) of the automobile 40 that stops charging the battery. You may make it be stopped automatically when elapses.

  In FIG. 5, the moving cell base station 30 may have a repeater function that functions as a radio relay station of the fixed base station 20. The moving cell base station 30 is assigned base station identification information (cell ID) that can be identified from other base stations, and can be connected to the backhaul line of the mobile communication network 10 via the fixed base station 20. It may have a function.

  FIG. 6 is a block diagram illustrating a configuration example of the base station apparatus 300 of the moving cell base station 30 according to the present embodiment. In FIG. 6, the base station device 300 of the moving cell base station 30 is configured to be installed in the automobile 40 and is installed in the fixed base station 20 or other mobile body via the first antenna 350. A first wireless communication unit 302 that performs wireless communication with the user device 50, a second wireless communication unit 304 that performs wireless communication with the user device 50 via the second antenna 370, a relay control unit 306, and a storage unit 308. The relay control unit 306 forms a moving cell 30A in at least an outer peripheral area of the automobile 40, and the user apparatus 50 located in the moving cell 30A and another base station installed in the fixed base station 20 or another mobile body The first wireless communication unit 302 and the second wireless communication unit 304 are controlled so as to relay communication with the apparatus.

  The base station apparatus 300 may include a power source (battery) in its own apparatus, but may receive power from the battery 41 on the automobile 40 side. In this case, the supply of power from the battery 41 to the base station apparatus is performed by turning off the key of the automobile 40 that stops charging the battery 41 so that the remaining charge capacity of the battery 41 does not become a predetermined capacity or less (driving stop). It may be controlled to automatically stop when a predetermined time (for example, 1 hour) elapses. The time until the automatic stop may be set based on the remaining charge capacity of the battery 41 or the like.

  In the moving cell base station 30, the frequency band used for wireless communication with the fixed base station 20 and the frequency band used for wireless communication with the user apparatus 50 may be different from each other. For example, as a frequency band used for wireless communication with the fixed base station 20, a high-frequency communication band of 5 G (fifth generation) such as a 28 GHz band, a 5 GHz band, or a 4.2 GHz band is used. As a frequency band used for wireless communication, a 2.6 GHz band, a 700 MHz band, or a 2 GHz band may be used. By using different frequency bands in this way, the moving cell base station 30 can reliably perform each wireless communication while avoiding interference between the wireless communication with the fixed base station 20 and the wireless communication with the user device 50. It can be carried out.

  Also, in the base station device 300 of the moving cell base station 30, the transmission power and reception sensitivity of the first radio communication unit 302 for the fixed base station 20 are higher than the transmission power and reception sensitivity of the user device 50 for the fixed base station 20. You may comprise as follows. In this case, the moving cell base station 30 has a higher communication quality with the fixed base station 20 in the area of the cell boundary of the cell 20A of the fixed base station 20 to which the user apparatus 50 can communicate and the out-of-service area in the vicinity thereof. Communication is possible, and the moving cell 30A can be formed in the area. Accordingly, local traffic offload can be reliably performed in the cell 20A of the fixed base station 20, and the mobile communication area can be substantially expanded without increasing the number of the fixed base stations 20. Further, the moving cell base station 30 may be connected simultaneously with the plurality of fixed base stations 20, set up a plurality of lines, and increase the capacity of the line between the moving cell base station 30 and the fixed base station 20 ( (Increased line capacity between fixed base station group and moving cell base station due to line aggregation by multiple fixed base station sites).

  The relay control unit 306 may control the base station device 300 so as to function as a wireless relay station (repeater). Further, the relay control unit 306 is assigned with base station identification information (cell ID) that can be distinguished from other base stations, and controls to connect to the backhaul line of the mobile communication network 10 via the fixed base station 20. It may be a thing.

  In addition, the relay control unit 306 performs the first handover process accompanying the movement of the own station (moving cell base station) 30 with respect to the fixed base station 20, the own station (moving cell base station) 30, and the user apparatus 50 as follows. The second handover process associated with the relative movement between the two may be configured to allow simultaneous parallel processing. For example, the relay control unit 306 performs a handover process in which the local station 30 continues to connect to the mobile communication network 10 when the local station 30 moves across the cells 20A of the plurality of fixed base stations 20, and the local station When the user apparatus 50 moves relative to 30, the user apparatus 50 may be controlled to perform a handover process for continuing the connection with the mobile communication network 10. By such a double handover process, even when the moving cell 30A is formed as the local station 30 moves, the connection of the user apparatus 50 residing in the moving cell 30A to the mobile communication network 10 is disconnected. Can be avoided.

  Further, the relay control unit 306 may control the transmission power when the mobile station 30 is turned ON / OFF or the mobile cell is formed. This control is formed by, for example, the position information of the own station 30, the attitude information of the own station 30, the moving speed of the own station 30, and other base station devices provided in the automobile 40 located around the own station 30. You may perform based on the condition of a surrounding cell, and at least one of the control information from the outside. For example, the relay control unit 306 may control ON / OFF of the moving cell formation or transmission power at the time of moving cell formation based on the control information received from the management device 60 via the mobile communication network 10. Here, the position information of the own station 30, the attitude information of the own station 30, the moving speed of the own station 30, and the like are obtained from the GPS receiver and the direction sensor provided in the base station device 300 of the own station 30 and the main body of the automobile 40. The determination can be made based on the output or based on the location registration information of the own station 30.

  Further, in the communication system according to the present embodiment, the same frequency is not adjacent to the frequency used for the wireless communication with the user apparatus 50 on the moving route (for example, road) of the automobile 40 based on the arrangement of the fixed base station 20 or the like. A plurality of zones may be set as described above. The size of each zone is set to such a size that a plurality of moving cells can be arranged so as not to overlap each other. The length of each zone is, for example, 50 m to 1 km. Then, with such a plurality of zones set, the relay control unit 306 performs wireless communication with the user apparatus 50 for each of the plurality of zones using the frequency set in the zone where the local station 30 is located. You may control to do. For example, when the relay control unit 306 enters the automobile 40 in any one of the plurality of zones, the relay control unit 306 performs wireless communication with the user device 50 using a predetermined frequency set in the zone in which the automobile 40 is entered. Control to do. In this way, by performing wireless communication with the user apparatus 50 using a predetermined frequency for each zone, each zone can be regarded as a quasi-static cell, and the frequency of handover processing by the user apparatus 50 can be reduced. The burden can be suppressed.

  Further, the second antenna 370 of the moving cell base station 30 may have a beamforming function, and the relay control unit 306 may control at least one of the direction and the number of beams formed by the second antenna 370. For example, the control of the beam direction and the like is performed on a moving body such as a position information of the own station 30, an attitude information of the own station 30, a moving speed of the own station 30, and an automobile located around the own station 30. Can be performed based on at least one of the status of neighboring cells formed by the base station apparatus and control information from the outside. Here, the position information of the own station 30, the attitude information of the own station 30, the moving speed of the own station 30, and the like are obtained from the GPS receiver and the direction sensor provided in the base station device 300 of the own station 30 and the main body of the automobile 40. The determination can be made based on the output or based on the location registration information of the own station 30. In particular, the relay control unit 306 forms a beam in different directions in cooperation between the own station 30 and other moving cell base stations mounted on other nearby vehicles in a parking lot or the like. The station 30 and other moving cell base stations may be controlled to form one cell. The cooperative control by the plurality of moving cell base stations can be performed based on control information received via the mobile communication network 10 from the management device 60 that manages the moving cell base stations, for example. This control information is determined based on, for example, position information and attitude information of each moving cell base station.

  Further, in the base station apparatus 300 of the moving cell base station 30 of FIG. 6, the first radio communication unit 302 is configured by a terminal apparatus (including a control apparatus and a data modulation / demodulation apparatus) paired with the fixed base station 20, and the second The wireless communication unit 304 may be configured by a base station device similar to the base station device of the fixed base station 20.

  Next, a specific example of formation of the moving cell 30A by the moving cell base station 30 mounted on the automobile 40 in the communication system having the above-described configuration and communication service provision accompanying the formation of the moving cell 30A will be described.

  FIG. 7 is an explanatory diagram illustrating an example of a basic configuration of the moving cell 30A formed by the moving cell base station 30 according to the present embodiment. In FIG. 7, four units in which moving cell base stations 30 (1) to 30 (4) are mounted on cells 20A (1) to 20A (4) formed on a road 70 adjacent to a building such as a building. Automobiles 40 (1) to 40 (4) are respectively included. The moving cell base stations 30 (1) to 30 (4) of the automobiles 40 (1) to 40 (4) that have entered any area of the cells 20A (1) to 20A (4) are respectively connected to the fixed base station 20 ( Wireless communication is possible with any one of 1) to 20 (4), and it is connected to the backhaul line of the fixed base station. For example, the moving cell base station 30 (1) of the automobile 40 (1) can wirelessly communicate with the fixed base station 20 (1) and is connected to the backhaul line of the fixed base station 20 (1). The moving cell base station 30 (2) of the automobile 40 (2) can wirelessly communicate with the fixed base station 20 (2), and is connected to the backhaul line of the fixed base station 20 (2). The moving cell base station 30 (3) of the automobile 40 (3) can wirelessly communicate with the fixed base station 20 (3) and is connected to the backhaul line of the fixed base station 20 (3). Further, the moving cell base station 30 (4) of the automobile 40 (4) can wirelessly communicate with the fixed base station 20 (4) and is connected to the backhaul line of the fixed base station 20 (4).

And can communicate at a predetermined frequency f1.

  For example, when the distance between the automobile 40 (1) and the automobile 40 (2) is short, wireless communication can be performed between the moving cell base station 30 (1) and the moving cell base station 30 (2). is there.

A mobile communication service can be received via the base station 30. Further, by dynamically and ad hoc forming the moving cell 30A around the automobile 40, local traffic can be offloaded, and the area that cannot be covered by the cell 20A by the conventional fixed base station 20 is complemented. Can be done. In particular, since an antenna with higher performance than the user apparatus 50 can be mounted as an antenna for the moving cell base station 30 to communicate with the fixed base station 20, the area for forming the moving cell 30A is expanded, and the conventional fixed base station 20 is expanded.
