The cell diameter of the moving cell 30A is, for example, 100 m, and may be 20 m or less and 50 m or less.

  The moving cell base station 30 has a first antenna 350 for performing wireless communication between the base station apparatus 300 and another moving cell base station 30 installed in the fixed base station 20 or another mobile body. The moving cell 30A formed by the station device 300 is provided with a second antenna 370 that performs wireless communication with a 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 portion of a roof, a shark antenna portion at the rear of the roof incorporating an antenna for other application, or a pillar portion.

When power is supplied from the battery of the automobile 40, the supply of power from the battery to the base station apparatus 300 is a predetermined time (for example, one hour) from the shutdown (OFF) of the automobile 40 in which the charging of the battery is stopped. It may be automatically stopped when the time has passed.

  Further, in the communication system of FIG. 1, the moving cell base station 30 may have a repeater function that functions as a wireless relay station of the fixed base station 20. Also, the moving cell base station 30 is assigned base station identification information (cell ID) distinguishable 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.

4 to 6 are block diagrams showing configuration examples of the base station apparatus 300 of the moving cell base station 30 according to the present embodiment.
In FIG. 4, the base station apparatus 300 of the moving cell base station 30 is configured to be installable in the automobile 40, and another base station apparatus installed in the fixed base station 20 or another mobile via the first antenna 350. And 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 in at least the 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 to relay communication with the device.

  The base station apparatus 300 may include a power supply (battery) in its own apparatus, but may receive power supply from the battery 41 on the side of the automobile 40 as shown in FIG. 5. In this case, the supply of power from the battery 41 to the own base station apparatus turns off the key 40 of the automobile 40 whose charging to the battery 41 is stopped so that the remaining charge capacity of the battery 41 does not fall below a predetermined capacity. It may be controlled to automatically stop when a predetermined time (for example, one hour) has elapsed from The time until the automatic stop may be set based on the charge remaining 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 device 50 may be different from each other. For example, as a frequency band used for wireless communication with fixed base station 20, a 28 GHz band, 5 GHz band or 4.2 GHz band is used, and as a frequency band used for wireless communication with user apparatus 50, 2.6 GHz band, A 700 MHz band or 2 GHz band may be used. By using different frequency bands in this manner, moving cell base station 30 ensures that each wireless communication is performed while avoiding interference between the wireless communication with fixed base station 20 and the wireless communication with user apparatus 50. It can be carried out.

  Further, in the base station apparatus 300 of the moving cell base station 30, the transmission power and reception sensitivity for the fixed base station 20 of the first wireless communication unit 302 become higher than the transmission power and reception sensitivity for the fixed base station 20 of the user apparatus 50. It may be configured as follows. In this case, in the area of the cell boundary of cell 20A of fixed base station 20 with which user apparatus 50 can communicate or the out-of-service area in the vicinity thereof, moving cell base station 30 can achieve higher communication quality with fixed base station 20. It is possible to communicate, and the moving cell 30A can be formed in that area. Accordingly, local traffic offload 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 simultaneously connect a 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 (see FIG. Increase in channel capacity between a fixed base station group and a moving cell base station by line aggregation by multiple fixed base station sites).

  In addition, even in mountain trails and mountain trails where the signal strength from fixed base station 20 is weak, it is installed in car 40 traveling on the mountain trails and car 40 parked in parking lanes at the mountain trails The moving cell base station 30 can form a moving cell 30A around the automobile 40. Therefore, users along the mountain trail or users at the parking lot at the mountain climbing port and 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 radio relay station (repeater). The relay control unit 306 is also assigned 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 one.

  Further, relay control section 306 performs a first handover process accompanying movement of own station 30 relative to fixed base station 20 as follows, and a second handover process accompanying relative movement between own station 30 and user apparatus 50 May be configured to allow simultaneous parallel processing. For example, when the relay station 306 moves across the cells 20A of the plurality of fixed base stations 20, the relay control unit 306 performs a handover process to continue the connection with the mobile communication network 10 by the local station 30, and the local station When the user apparatus 50 moves relative to 30 relative to the mobile communication network 10, control may be performed to continue the handover process of continuing the connection with the mobile communication network 10 by the user apparatus 50. Even when the moving cell 30A is formed along with the movement of the local station 30 by such double handover processing, the connection of the user apparatus 50 located in the moving cell 30A to the mobile communication network 10 is disconnected. It can be avoided.

  In addition, relay control section 306 may control transmission power at the time of moving cell formation ON / OFF by local station 30 or moving cell formation. This control is formed, for example, by position information of the own station 30, attitude information of the own station 30, moving speed of the own station 30, and other base station devices provided in the automobile 40 located around the own station 30. It may be performed based on at least one of the status of the neighboring cell and control information from the outside. For example, relay control section 306 may control transmission power at the time of moving cell formation ON / OFF or moving cell formation based on control information received from management apparatus 60 via mobile communication network 10. Here, position information of the own station 30, attitude information of the own station 30, movement speed of the own station 30, and the like can be obtained from the GPS receiver or azimuth sensor provided on the base station apparatus 300 of the own station 30 or the main body of the car 40. It can be determined 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 does not adjoin on the moving route (for example, the road) of the automobile 40 based on the arrangement of the fixed base station 20 or the like. You may set up multiple zones. The size of each zone is set, for example, to such an extent that a plurality of moving cells can be arranged so as not to overlap each other. Also, the length of each zone is, for example, 50 m to 1 km. Then, with such a plurality of zones set, relay control section 306 performs wireless communication with user apparatus 50 using the frequency set in the zone in which local station 30 is located, for each of the plurality of zones. You may control to carry out. For example, the relay control unit 306 wirelessly communicates with the user device 50 using a predetermined frequency set in the zone in which the vehicle 40 enters when the vehicle 40 enters the zone in any of the plurality of zones. Control to do By wirelessly communicating with user apparatus 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 user terminal 50 can be reduced. The burden can be reduced.

  In addition, 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. The control of the direction of the beam, etc. is performed, for example, on position information of the own station 30, attitude information of the own station 30, moving speed of the own station 30, and other moving objects such as cars located around the own station 30. The present invention can be performed based on at least one of the condition of the neighboring cells formed by the base station apparatus of the above and control information from the outside. Here, position information of the own station 30, attitude information of the own station 30, movement speed of the own station 30, and the like can be obtained from the GPS receiver or azimuth sensor provided on the base station apparatus 300 of the own station 30 or the main body of the car 40. It can be determined based on the output or based on the location registration information of the own station 30. In particular, relay control section 306 cooperates between self station 30 and other moving cell base stations mounted on other vehicles in the vicinity in a parking lot etc. to form beams in mutually different directions. 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 from the management device 60 managing the moving cell base station via the mobile communication network 10, for example. The control information is determined based on, for example, position information and attitude information of each moving cell base station.

  Further, as shown in FIG. 6, the base station apparatus 300 includes a data processing unit 310 that processes data to be transmitted / received to / from the user apparatus 50, the fixed base station 20, or a base station apparatus of a nearby mobile unit. The processing unit 310 may be used for various applications to cause the moving cell base station 30 to function as a movable local data center.

  For example, the data processing unit 310 provides information to be provided to the user apparatus 50, the fixed base station 20, or a base station apparatus of a mobile such as a nearby automobile, and data of area information regarding the area where the automobile 41 including the own station 30 is located. , Data of map information of the area, data of navigation of the area, data of automatic driving of the moving body of the car 40 in the area, image data of a still image or moving picture photographed by the car 40, moving bodies such as surrounding cars Image data of a still image or a moving image photographed in the above, image data of a still image or a moving image photographed by a base station apparatus provided in a mobile object such as a nearby automobile, and the user device 50 connected to the own station 30 The image data of at least one of the still image or the moving image photographed in the above may be generated, stored in the storage unit 308, or read from the storage unit 308. In this case, the relay control unit 306 performs the at least one data autonomously or in response to a request from the user apparatus 50, the fixed base station 20, or a base station apparatus of a nearby mobile unit, the user apparatus 50, the fixed base station Control to transmit to or receive from a base station apparatus of a mobile unit such as a vehicle of 20 or nearby.

  By including the data processing unit 310 and the relay control unit 306 configured as described above, the moving cell base station 30 can, for example, use a user whose area information downloaded from a server on the mobile communication network 10 side is located in the moving cell 30A. It may be transmitted to the device 50, or the area information uniquely acquired by the user device 50 or the car 40 may be received and stored in the own station 30, or uploaded to a server on the mobile communication network 10 side. In addition, the moving cell base station 30 functions as the user device 50 serving as the user device 50 located in the moving cell 30A, with detailed navigation data and automatic driving data of the surrounding area downloaded from the server on the mobile communication network 10 side. It may be sent to a navigation system or an autonomous driving system. In addition, the moving cell base station 30 receives information such as navigation data acquired by the user device 50 or the car 40 itself or information on surrounding roads for data for automatic driving, and stores the information in the local station 30 or Based on the received information, the navigation data and the data for automatic driving are generated, or the received information or the generated data for navigation and data for automatic driving are uploaded to the server on the mobile communication network 10 side. It is also good.

  Further, the data is data to be transported (for example, data of a large-capacity book or movie purchased on the Internet etc. that does not require urgency) transported via movement of the automobile 40 equipped with the own station 30. May be In this case, the data processing unit 310 stores and reads out data to be transported that is transmitted to and received from the user apparatus 50, the fixed base station 20, or a mobile base station such as a nearby automobile. In addition, relay control section 306, in response to a request from user apparatus 50, fixed base station 20 or a base station apparatus of a nearby mobile unit, or autonomously carries data to be transported, user apparatus 50, fixed base station 20 or After receiving from the base station device of the surrounding mobile unit and moving the car 40 equipped with the own station 30 to a predetermined position, according to the request from the user device 50, the fixed base station 20 or the base station device of the surrounding mobile unit. The data to be transported is controlled to be transmitted to the user apparatus 50, the fixed base station 20, or the base station apparatus of a mobile unit in the vicinity, either autonomously or autonomously. By the above control, for example, data of a large capacity book or movie having no urgency can be transported to a predetermined transport destination without passing through the mobile communication network 10, so the load on the mobile communication network 10 is suppressed. can do.

  The above data may be transported by a single automobile 40 equipped with the moving cell base station 30, or a plurality of automobiles 40 equipped with the moving cell base station 30 cooperate to sequentially transfer the transport. You may do so. The data transfer between the plurality of vehicles 40 may be performed by direct communication between the moving cell base stations 30 mounted on each of the plurality of vehicles 40 or may be performed by communication via the fixed base station 20.

  Further, in the base station apparatus 300 of the moving cell base station 30 of FIGS. 4 to 6, the first wireless 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. The second 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, formation of the moving cell 30A by the moving cell base station 30 mounted on the automobile 40 in the communication system configured as described above, and communication service provision accompanying the formation of the moving cell 30A explain.

  FIG. 7 is an explanatory drawing showing an example of the basic configuration of the moving cell 30A formed by the moving cell base station 30 according to this embodiment. In FIG. 7, three automobiles 40 (1) having moving cell base stations 30 (1) to 30 (3) mounted in a predetermined zone 701 preset on a road 70 to which a building such as a building is adjacent. )-40 (3) are included respectively. The zone 701 is located in the cell 20A of the fixed base stations 20 (1) to 20 (4), the cell boundary or the cell periphery. Moving cell base stations 30 (1) to 30 (3) of vehicles 40 (1) to 40 (3) that have entered zone 701 respectively communicate wirelessly with any of fixed base stations 20 (1) to 20 (4) It is possible and connected to the backhaul circuit of the fixed base station. For example, the moving cell base stations 30 (1) and 30 (3) of the two cars 40 (1) and 40 (3) can wirelessly communicate with the fixed base station 20 (1), and the fixed base station 20 can It is connected to the backhaul circuit of (1). Also, the moving cell base station 30 (2) of one car 40 (2) can communicate wirelessly with the fixed base station 20 (3), and is connected to the backhaul line of the fixed base station 20 (3). There is. In addition, moving cell base stations 30 (1) to 30 (3) each form a small sized moving cell 30 A in the peripheral area, and user equipment 50 located in moving cell 30 A and a predetermined number corresponding to zone 701. It can communicate on frequency f1.

  As shown in FIG. 7, by dynamically and ad hocly forming the moving cells 30 A around the automobile 40, users such as bus waiting along the road 70 can move the cells without being affected by the building 71. Communication service of mobile communication can be received via the base station 30. Also, by forming moving cells 30A dynamically and ad hoc around automobile 40, it becomes possible to offload local traffic and complement the area that can not be covered by cell 20A by the conventional fixed base station 20. Can do. In particular, since the moving cell base station 30 can be equipped with an antenna of higher performance than the user terminal 50 as an antenna for communicating with the fixed base station 20, the area for forming the moving cell 30A is expanded, and the conventional fixed base station 20 The area that can not be covered by the cell 20A can be complemented more reliably.

  FIG. 8 is an explanatory drawing showing an example of the dynamic control of the backhaul line in the moving cell formed by the moving cell base station according to the present embodiment. In FIG. 8, the same parts as in FIG. 7 will be assigned the same reference numerals, and descriptions thereof will be omitted.

  In FIG. 8, a plurality of zones 701 and 702 are continuously set on the road 70 so that the same frequency is not adjacent as a frequency used in wireless communication with the user terminal 50. In the central zone 701, the frequency f1 is used for wireless communication with the user terminal 50, and in the zones 702 on both sides thereof, the frequency f2 (= f1) is used for wireless communication with the user terminal 50.

  The moving cell base station 30 (4) of the automobile 40 (4) in the zone 702 on the right in FIG. 8 can communicate with the fixed base station 20 (1) by radio, and the back of the fixed base station 20 (1) Connected to the hall circuit. The moving cell base station 30 (5) of the automobile 40 (5) in the zone 702 is capable of wirelessly communicating with the fixed base station 20 (4), and the backhaul of the fixed base station 20 (4) It is connected to the line. In addition, moving cell base stations 30 (6) and 30 (7) of vehicles 40 (6) and 40 (7) in zone 702 on the left side in FIG. 8 can communicate with fixed base station 20 (3) by radio. And is connected to the backhaul circuit of the fixed base station 20 (3).

  Here, when the automobile 40 (6) located in the zone 702 on the left side in FIG. 8 moves and moves to the central zone 701, the moving cell base station 30 (6) of the automobile 40 (6) is connected back The hand between the fixed base stations 20 (3) and 20 (1) so that the hall link dynamically switches from the backhaul link of the fixed base station 20 (3) to the backhaul link of the fixed base station 20 (1). The over control provides dynamic control of the backhaul circuit.
