[0020] Hereinafter, the present invention will be described by way of the embodiments of the invention, but the following embodiments do not limit the claimed invention. In addition, not all combinations of features described in the embodiments are essential to the solution means of the present invention.

[0021] Figure 1 The use scenario of the communication system 10 is schematically shown. The communication system 10 includes a vehicle 20, a vehicle 21, a vehicle 22, an external device 70, a base station 12, and a wireless access point 14. The vehicle 20, the vehicle 21, and the vehicle 22 are automobiles. The vehicle 20, the vehicle 21, and the vehicle 22 are examples of "mobile bodies".

[0022] The communication network 90 includes an IP network such as the Internet, a P2P network, a dedicated line including a VPN, and a virtual network, a mobile communication network, etc. The communication network 90 is connected to the base station 12 and the wireless access point 14. The base station 12 is a base station belonging to the mobile communication network.

[0023] The wireless access point 14 is, for example, a wireless LAN access point. The wireless access point 14 may be a public wireless LAN access point. The wireless access point 14 may be a wireless access point installed in a transportation infrastructure. The wireless access point 14 may be a wireless access point installed in a facility near a transportation infrastructure. The wireless access point 14 may be a wireless access point installed in a parking lot, etc.

[0024] The vehicle 20 is provided with a communication device 40. The vehicle 21 is provided with a communication device 41. The vehicle 22 is provided with a communication device 42. The communication device 40, the communication device 41 and the communication device 42 have the same function. Specifically, the communication device 40, the communication device 41 and the communication device 42 respectively have a function of performing mobile communication through the base station 12 and a function of performing wireless LAN communication. The communication device 40, the communication device 41 and the communication device 42 respectively have a function of performing Bluetooth (registered trademark) communication. The communication device 40, the communication device 41 and the communication device 42 have a function of performing direct wireless communication with each other. The communication device 40, the communication device 41 and the communication device 42 can directly communicate with other communication devices through short-range direct communication (for example, V2V direct communication) in Cellular-V2X (cellular V2X). As short-range direct communication in Cellular-V2X, there are communication methods such as LTE-V2X PC5 and 5G-V2X PC5.

[0025] The terminal 30 is a communication terminal held by a passenger of the vehicle 20. The terminal 30 is a mobile terminal such as a mobile phone or a smart phone. The terminal 30 has a function of performing mobile communication through the base station 12. In addition, the terminal 30 has a function of operating as a wireless access point. The terminal 30 has an online function of relaying a device connected to the wireless access point provided by the terminal 30 and connecting the device to the communication network 90 through the base station 12.

[0026] like Figure 1 As shown, the communication device 42 can be connected to the wireless access point 14, but the communication device 40 and the communication device 41 cannot be connected to the wireless access point 14. The communication device 40 can directly communicate with the communication device 41, and the communication device 41 can directly communicate with the communication device 42. In this case, when the communication device 40 communicates with the external device 70, the communication cost when communicating with the external device 70 through the first communication path via the communication device 41, the communication device 42, and the wireless access point 14 is compared with the communication cost when communicating with the external device 70 through the second communication path via the terminal 30, and when the communication cost when communicating through the first communication path is lower than the communication cost when communicating through the second communication path, the first communication path is selected and the communication is performed with the external device 70.

[0027] For example, the communication device 40 acquires communication cost information when the communication device 41 directly communicates with other communication devices or wireless access points, and communication cost information when the communication device 42 directly communicates with other communication devices. For example, the communication cost information about the communication device 41 may be, for example, information on the amount charged to the contracting party of the communication device 41 when the communication device 41 directly communicates with other communication devices. The communication cost information may be information on the amount charged per unit data volume in the case of performing direct communication.

[0028] The communication device 40, the communication device 41, and the communication device 42 respectively transmit request information for requesting the communication environment information by broadcasting, thereby acquiring the communication environment information from the communication devices of other vehicles. For example, if the request information is received from the communication device 41, the communication device 42 transmits the communication environment information 52 to the communication device 41. If the request information is received from the communication device 40, the communication device 41 transmits the communication environment information 51 to the communication device 40.

[0029] The communication environment information 51 and the communication environment information 52 include data items of "VID", "WiFi connection", "cost" and "direct communication", respectively. "VID" is the vehicle identification information of the vehicle. "WiFi connection" is information indicating whether a wireless LAN connection can be established with a wireless access point. "Cost" is communication cost information. "Direct communication" is information indicating the VID of a vehicle equipped with other communication devices capable of direct communication.

[0030] For example, the communication environment information 52 indicates that the communication device 42 can establish a wireless LAN connection with the wireless access point, the communication cost is Y2 yen per unit data volume, and there is no vehicle that can directly communicate. The communication environment information 51 includes communication environment information 51-1 and communication environment information 51-2. In the communication environment information 51-1, the same information as the communication environment information 52 received from the communication device 42 is set. The communication environment information 51-1 is the communication environment information of the communication device 41. The communication environment information 51-1 indicates that the communication device 41 cannot establish a wireless LAN connection with the wireless access point, the communication cost is Y1 yen per unit data volume, and it can directly communicate with the communication device 41 of the vehicle 22 with a VID of X2 and the communication device 40 of the vehicle 20 with a VID of X0.

[0031] Based on the communication environment information 51 received from the communication device 40, the communication device 40 determines that the communication device 41 can communicate directly with the communication device 42 and that the communication device 42 can connect to the wireless access point. In addition, the communication device 40 calculates a communication cost C1 based on the communication environment information 51, which is a cost when data of a data amount A is sent to the external device 70 by connecting to the communication network 90 via the communication path of the communication device 41, the communication device 42, and the wireless access point in sequence. For example, the communication device 40 calculates the communication cost C1 by C1=Y0×A+Y1×A+Y2×A. Here, Y0 is a cost when the communication device 40 communicates directly with other communication devices. It is assumed that Y0 is set in advance in the communication device 40 by the user of the vehicle 20.

[0032] In addition, the communication device 40 calculates the communication cost C2 when the terminal 30 transmits data of data volume A through the base station 12. For example, if the cost when the communication device 40 directly communicates with other communication devices is set to y0, the communication device 40 calculates the communication cost C2 by y0×A. It is assumed that y0 is set in advance in the communication device 40 by the user of the terminal 30. When the communication cost C1 is lower than the communication cost C2, the communication device 40 selects the communication path via the communication device 41, the communication device 42, and the wireless access point in sequence to connect to the communication network 90 and transmit the data to the external device 70.

[0033] The communication device 41 and the communication device 42 include the contract party information of the respective communication devices in the packet with the communication device 40 as the transmission source. The communication carrier calculates the communication fee corresponding to the communication performed via the communication path of the communication device 41 and the communication device 42 with the communication device 40 as the transmission source based on the contract party information included in the packet transmitted from the vehicle 20, and charges the contract party of the communication device 40, but does not charge the contract party of the communication device 41 or the contract party of the communication device 42. Thus, even when the communication device 41 and the communication device 42 relay data communication with the communication device 40 as the transmission source, the contract party of the communication device 40 can be charged appropriately.

[0034] As described above, according to the communication system 10, when the vehicle 20 is in a state where it can connect to the wireless access point 14 by direct communication with other vehicles, the user of the vehicle 20 can connect to the wireless access point 14 by direct communication with other vehicles using a communication path, thereby reducing communication costs. In addition, for example, when the vehicle 20 communicates through a communication path that sequentially passes through the vehicle 21, the vehicle 22, and the wireless access point 14, it is possible to prevent the user of the vehicle 21 and the user of the vehicle 22 from bearing the communication fee generated by data communication with the vehicle 20 as the transmission source. As a result, the user of the vehicle 20 can bear appropriate communication fees.

[0035] Figure 2 The system configuration of the communication device 40 is shown. The communication device 40 includes a communication unit 290 and a communication control device 292. The communication unit 290 is responsible for communication with the outside. For example, the communication unit 290 is responsible for direct communication with other vehicle communication devices. The communication unit 290 can be implemented by a TCU (Telematics Control Unit).

[0036] The communication control device 292 controls the wireless communication of the vehicle 20. The communication control device 292 controls the communication unit 290. The communication control device 292 includes a processing unit 200 and a storage unit 280. The processing unit 200 is implemented by, for example, a calculation processing device including a processor. The storage unit 280 is implemented by including a non-volatile storage medium. At least a part of the processing unit 200 and the storage unit 280 can be implemented by an ECU (Electronic Control Unit) having a microcomputer including a CPU, ROM, RAM, I / O, and a bus. The processing unit 200 uses the information stored in the storage unit 280 for processing.

[0037] The processing unit 200 includes a cost information acquisition unit 210, a connection information acquisition unit 220, a communication path setting unit 230, a communication path selection unit 240, and a communication control unit 270. The cost information acquisition unit 210 acquires cost information consumed by other vehicles 20 for performing direct wireless communication between the other vehicles 20 existing around the vehicle 20. The connection information acquisition unit 220 acquires communication connection information available to the other vehicles 20. The cost information may be information set in the "cost" data item of the above-mentioned communication environment information. The communication connection information may be information set in the data items of "direct communication" and "WiFi connection" of the above-mentioned communication environment information.

[0038] The communication path setting unit 230 sets a plurality of communication paths including a communication path for direct communication with other vehicles 20 based on the communication connection information. For example, the communication path setting unit 230 selects a communication path that passes through the communication device 41 and the communication device 42 in sequence as one communication path. The communication path selection unit 240 selects a communication path for data communication from the plurality of communication paths based on the cost information acquired by the cost information acquisition unit 210 and the communication connection information acquired by the connection information acquisition unit 220. Specifically, the communication path selection unit 240 selects a communication path with the lowest cost from the plurality of communication paths based on the cost information acquired by the cost information acquisition unit 210 and the communication connection information acquired by the connection information acquisition unit 220.

[0039] The end point of the communication path using direct communication with other vehicles 20 is the vehicle 20 that can be connected to the Internet communication through narrowband wireless communication. Figure 1 In the example of FIG. 1 , the vehicle 22 that can be connected to the Internet communication via wireless LAN communication becomes the end point of the communication path.

[0040] The communication control unit 270 broadcasts a request message for communication connection information available to other vehicles 20. In response to the request message, the connection information acquisition unit 220 acquires communication connection information available to other vehicles 20 from other vehicles 20. The request message may request cost information consumed by other vehicles 20 for performing direct wireless communication between vehicles 20. In response to the request message, the cost information acquisition unit 210 acquires cost information consumed by other vehicles 20 for performing direct wireless communication between vehicles 20. Figure 1 The described request information is an example of request information requesting communication connection information and cost information.

[0041] Figure 3 An example of setting a plurality of communication paths including direct communication is schematically shown. Figure 3 Shown in combination Figure 1 The communication system 10 is described in which the vehicle 23 exists in addition to the vehicles 20 , 21 , and 22 , and the wireless access point 15 to which the vehicle 23 can connect exists in addition to the wireless access point 14 .

[0042] The vehicle 23 is provided with a communication device 43. The communication device 43 has the same functions as the communication devices 40, 41, and 42. Figure 1 As stated, Figure 3 The communication path 300 in FIG. 1 is a communication path that passes through the communication device 41 , the communication device 42 , and the wireless access point 14 in sequence.

[0043] exist Figure 3 In the embodiment, it is assumed that the vehicle 23 is in a position where the communication device 43 of the vehicle 23 can directly communicate with the communication device 41 of the vehicle 21. When the request information is received from the communication device 40, the communication device 41 transmits the communication environment information including the communication environment information of the communication device 43 in addition to the communication environment information of the communication device 42 and the communication environment information of the communication device 41 to the communication device 40. In this case, in addition to the communication path 300, the communication path setting unit 230 of the communication device 40 sets the communication path 310 which passes through the communication device 41, the communication device 43 and the wireless access point 15 in sequence based on the communication environment information.

[0044] As reference Figure 1As described, the communication path selection unit 240 calculates the communication cost C1 when passing through the communication path 300 based on the communication environment information, and calculates the communication cost C3 when passing through the communication path 310. And, when the communication cost C3 is the lowest among the communication cost C1, the above-mentioned communication cost C2, and the communication cost C3, the communication path selection unit 240 selects the communication path 300 as the communication path for data transmission.

[0045] Figure 4 4 is a flowchart showing an example of a processing procedure executed by the communication device 40. The processing of this flowchart is started when data communication is performed with the external device 70. In S402, the cost information acquisition unit 210 acquires cost information. In S404, the connection information acquisition unit 220 acquires connection information.

[0046] In addition, the cost information acquisition unit 210 may acquire the cost information from the communication environment information collected in advance, and the connection information acquisition unit 220 may acquire the connection information from the communication environment information collected in advance. As another form, in the case of starting data communication with the external device 70, the communication control unit 270 may transmit request information from the communication unit 290 by broadcasting, and the cost information acquisition unit 210 and the connection information acquisition unit 220 may acquire the cost information and the connection information from the communication environment information received from the communication device of the other vehicle, respectively, according to the request information.

[0047] In S406, the communication path setting unit 230 sets the communication path based on the connection information. In S408, the communication path selection unit 240 calculates the communication cost of each communication path based on the cost information and the connection information. In S410, the communication path selection unit 240 selects a communication path based on the communication cost of each communication path.

[0048] In S412, the communication control unit 270 controls the communication unit 290 to use the communication path selected in S410 to perform data communication with the external device 70. The communication control unit 270 may control the communication unit 290 to notify the communication devices of other vehicles 20 on the communication path selected in S410 of the communication path information from the communication device 40 to the wireless access point, and instruct each communication device to route the packet with the vehicle 20 as the transmission source according to the communication path information.

[0049] According to the communication system 10, the communication device 40 of the vehicle 20 can communicate with the external device 70 through a wireless access point using a communication path including direct communication between vehicles, thereby reducing communication costs. In addition, the contracting party of the communication device of other vehicles does not need to bear the communication costs generated by data communication using the vehicle 20 as the transmission source.

[0050] In addition, although the example of determining the communication path when transmitting data is mainly described in the present embodiment, it is also possible to apply a method of setting the communication path when receiving data.

[0051] In this embodiment, the cost included in the communication environment information may include, for example, an amount charged as a communication fee per unit of data volume. When the direct communication usage fee is charged at a fixed amount, the cost included in the communication environment information may include a value obtained by multiplying the fixed amount of usage fee by a predetermined constant.

[0052] In addition, the communication environment information transmitted to the communication device 41, the communication device 42, and the communication device 43 may further include information indicating the communication quality of the direct communication. The communication path selection unit 240 may further select a communication path based on the information indicating the communication quality included in the communication environment information. For example, the communication path selection unit 240 may select a communication path that can communicate with a communication quality greater than a predetermined reference value from a plurality of communication paths.

[0053] As described in conjunction with the above embodiments, the vehicle 20 may be a car. The vehicle 20 may be a car having an internal combustion engine. The vehicle 20 may be an electric vehicle equipped with a battery as a driving power source. The vehicle 20 may be an electric vehicle equipped with a fuel cell as a driving power source. The vehicle 20 may be a saddle-type vehicle. The vehicle 20 may be an electric vehicle. The vehicle 20 is an example of a transportation device. The vehicle 20 may be a mobile object other than a car.

[0054] Figure 5 An example of a computer 2000 that can fully or partially embody multiple embodiments of the present invention is shown. The program installed in the computer 2000 can make the computer 2000 function as a device such as a communication control device involved in the embodiment or each unit of the device, perform operations associated with the device or each unit of the device, and / or perform a process involved in the embodiment or steps of the process. Such a program can be executed by the CPU 2012 in order to make the computer 2000 perform the processing flow described in this specification and specific operations associated with some or all of the functional blocks in the block diagram.

[0055] The computer 2000 according to the present embodiment includes a CPU 2012 and a RAM 2014, which are connected to each other via a main controller 2010. The computer 2000 further includes a ROM 2026, a flash memory 2024, a communication interface 2022, and an input / output chip 2040. The ROM 2026, the flash memory 2024, the communication interface 2022, and the input / output chip 2040 are connected to the main controller 2010 via the input / output controller 2020.

[0056] The CPU 2012 operates according to the programs stored in the ROM 2026 and the RAM 2014 , thereby controlling each unit.

[0057] The communication interface 2022 communicates with other electronic devices via a network. The flash memory 2024 stores programs and data used by the CPU 2012 in the computer 2000. The ROM 2026 stores a startup program executed by the computer 2000 when activated, and / or a program dependent on the hardware of the computer 2000. The input / output chip 2040 can also connect various input / output units such as a keyboard, a mouse, and a monitor to the input / output controller 2020 via an input / output port such as a serial port, a parallel port, a keyboard port, a mouse port, a monitor port, a USB port, and an HDMI (registered trademark) port.

[0058] The program is provided via a computer-readable medium such as a CD-ROM, a DVD-ROM, or a USB flash drive, or a network. RAM 2014, ROM 2026, or flash memory 2024 is an example of a computer-readable medium. The program is installed in flash memory 2024, RAM 2014, or ROM 2026 and executed by CPU 2012. The information processing described in these programs is read by computer 2000, and the cooperation between the program and the various types of hardware resources described above is realized. The device or method can be constructed by implementing the operation or processing of information in accordance with the use of computer 2000.

[0059] For example, when the computer 2000 communicates with an external device, the CPU 2012 may execute a communication program loaded into the RAM 2014, and based on the processing described in the communication program, instruct the communication interface 2022 to perform communication processing. Under the control of the CPU 2012, the communication interface 2022 reads the transmission data stored in the transmission buffer processing area provided in the RAM 2014 and the recording medium such as the flash memory 2024, transmits the read transmission data to the network, and writes the reception data received from the network to the reception buffer processing area provided on the recording medium.

[0060] In addition, the CPU 2012 can read all or part of a file or database stored in a recording medium such as the flash memory 2024 to the RAM 2014, and perform various processes on the data in the RAM 2014. The CPU 2012 then writes the processed data back to the recording medium.

[0061] Various types of information such as programs, data, tables, and databases can be saved to a recording medium and applied to information processing. CPU2012 can perform various operations, information processing, conditional judgment, conditional branching, unconditional branching, information retrieval / replacement, etc., which are specified by the instruction sequence of the program, on the data read from RAM2014, and write the results back to RAM2014. In addition, CPU2012 can retrieve information in files, databases, etc. in the recording medium. For example, when multiple items having attribute values ​​of the first attribute associated with the attribute value of the second attribute are stored in the recording medium, CPU2012 can retrieve an item that specifies the attribute value of the first attribute and is consistent with the condition from the multiple items, read the attribute value of the second attribute stored in the item, and thereby obtain the attribute value of the second attribute associated with the first attribute that meets the pre-set condition.

[0062] The program or software module described above can be stored in a computer-readable medium on or near the computer 2000. A recording medium such as a hard disk or RAM provided in a server system connected to a dedicated communication network or the Internet can be used as a computer-readable medium. The program stored in the computer-readable medium can be provided to the computer 2000 via a network.

[0063] The programs installed in the computer 2000 and causing the computer 2000 to function as the communication control device 292 can be run in the CPU 2012 and the like, thereby causing the computer 2000 to function as each unit of the communication control device 292. The information processing described in these programs is read into the computer 2000, thereby functioning as a specific unit in which software and the various hardware resources described above cooperate, that is, each unit of the communication control device 292. And, by using these specific units to realize the calculation or processing of information corresponding to the purpose of use of the computer 2000 in this embodiment, a unique communication control device 292 corresponding to the purpose of use is constructed.

[0064] Various embodiments are described with reference to block diagrams, etc. In the block diagram, each functional block may represent (1) a step of a process for performing an operation or (2) each unit of a device having the function of performing an operation. Specific steps and each unit may be implemented by a dedicated circuit, a programmable circuit supplied together with computer-readable instructions stored on a computer-readable medium, and / or a processor supplied together with computer-readable instructions stored on a computer-readable medium.
