4 to 6 are block diagrams each illustrating a configuration example of the base station device 300 of the moving cell base station 30 according to the present embodiment.
In FIG. 4, base station apparatus 300 of moving cell base station 30 is configured to be installable in automobile 40, and is another base station apparatus installed in fixed base station 20 or another mobile object via 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, and a relay control unit 306. The relay control unit 306 forms the moving cell 30A at least in a peripheral area outside the automobile 40, and the user apparatus 50 located in the moving cell 30A and the fixed base station 20 or another base station installed in 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 device.

  The base station apparatus 300 may include a power supply (battery) in its own apparatus, or may receive power supply from the battery 41 of the automobile 40 as shown in FIG. In this case, the power supply from the battery 41 to the own base station apparatus is performed by the key OFF (stop of driving) of the automobile 40 in which the charging of the battery 41 is stopped so that the remaining charge capacity of the battery 41 does not fall below the predetermined capacity. May be controlled so as to automatically stop when a predetermined time (for example, one hour) has elapsed from the start. The time until the automatic stop may be set based on the remaining charge 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 device 50 may be different from each other. For example, a 28 GHz band, a 5 GHz band, or a 4.2 GHz band is used as a frequency band used for wireless communication with the fixed base station 20, and a 2.6 GHz band is used as a frequency band used for wireless communication with the user device 50. A 700 MHz band or a 2 GHz band may be used. By using different frequency bands as described above, the moving cell base station 30 reliably performs 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.

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

  Further, even in a mountain road or a parking lot at a mountain entrance where the radio wave intensity from the fixed base station 20 is weak, the vehicle is mounted on the automobile 40 running on the mountain path or the automobile 40 parked in the mountain entrance parking lot. The moving cell base station 30 can form a moving cell 30 </ b> A around the vehicle 40. Therefore, a user along a mountain trail or a user at a parking lot at a mountain entrance or in the vicinity thereof can use the mobile communication service via the moving cell base station 30.

  Relay control section 306 may control base station apparatus 300 to function as a wireless relay station (repeater). Further, the relay control unit 306 is assigned base station identification information (cell ID) that can be identified from other base stations, and performs control to connect to the backhaul line of the mobile communication network 10 via the fixed base station 20. It may be something.

  Further, the relay control unit 306 performs a first handover process accompanying the movement of the own station 30 with respect to the fixed base station 20 and a second handover process accompanying the relative movement between the own station 30 and the user device 50 as follows. May be configured to allow simultaneous parallel processing. For example, the relay control unit 306 performs a handover process of continuing the connection with the mobile communication network 10 by the own station 30 when the own station 30 moves across the cells 20A of the plurality of fixed base stations 20. When the user device 50 relatively moves with respect to 30, the control may be performed such that a handover process for continuing the connection with the mobile communication network 10 by the user device 50 is performed. By such a double handover process, even when the moving cell 30A is formed as the own station 30 moves, the connection of the user apparatus 50 located in the moving cell 30A to the mobile communication network 10 is cut off. Can be avoided.

  Further, relay control section 306 may control ON / OFF of moving cell formation by own station 30 or transmission power at the time of moving cell formation. 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 another base station device provided in the automobile 40 located around the own station 30. This may be performed based on at least one of the situation of the neighboring cells and control information from the outside. For example, the relay control unit 306 may control the ON / OFF of the moving cell formation or the transmission power at the time of the 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 determined by the GPS receiver and the azimuth 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 as the frequency used in the wireless communication with the user terminal 50 is not adjacent to the moving route (for example, the road) of the automobile 40 based on the arrangement of the fixed base station 20 and the like. A plurality of zones may be set as described above. The size of each zone is set to a size such 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, in a state where the plurality of zones are set, the relay control unit 306 performs wireless communication with the user device 50 using the frequency set in the zone where the own station 30 is located for each of the plurality of zones. It may be controlled so as to perform. For example, when the relay control unit 306 enters the vehicle 40 in any one of the plurality of zones, the relay control unit 306 wirelessly communicates with the user device 50 using a predetermined frequency set in the zone where the vehicle 40 has entered. Is controlled to be performed. By performing wireless communication with the user device 50 using a predetermined frequency for each zone in this manner, each zone can be regarded as a quasi-static cell, and the frequency of handover processing by the user terminal 50 is reduced. The burden can be reduced.

  Further, the second antenna 370 of the moving cell base station 30 may have a beam forming 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. The control of the direction of the beam and the like is performed, for example, on the location information of the own station 30, the attitude information of the own station 30, the moving speed of the own station 30, and other information provided on a moving body such as an automobile located around the own station 30. And the control information from outside from the surrounding cells formed by the base station device. 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 determined by the GPS receiver and the azimuth 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 beams in mutually different directions in cooperation with the own station 30 and other moving cell base stations mounted on other nearby vehicles in a parking lot or the like, thereby forming the own station. Control may be performed so that the station 30 and another moving cell base station form one cell. The cooperative control by the plurality of moving cell base stations can be performed, for example, based on control information received via the mobile communication network 10 from the management device 60 that manages the moving cell base stations. The control information is determined based on, for example, position information and attitude information of each moving cell base station.
