For example, if the combination of device type, model, serial number, and software included in the device information received from the target device 2 matches the condition information stored in the storage unit 12, the information processing device 1 It is determined that the device location information received from the target device 2 is to be transmitted to the server 4. Note that in the example shown in FIG. 3, "*" indicates that the condition is not specified, that is, it is a wild card. For example, if the type of device is "drone", the model is "A", and the serial number of target device 2 is "PKMMN", "UUUHB", what kind of serial number and software is used for positioning? In this case, it is determined that the device position information received from the target device 2 is to be transmitted to the server 4.

The communication unit 21 is a communication interface for transmitting and receiving data to and from the user terminal 3 via a communication network such as a wireless LAN. Note that the communication unit 21 may function as a communication interface for communicating with the information processing device 1 via a communication network such as the Internet or a mobile phone communication network.

The storage unit 22 is a storage medium that stores various data, and includes a ROM, a RAM, a hard disk, an SSD, and the like. The storage unit 22 stores programs executed by the control unit 23. The storage unit 22 stores a program that causes the control unit 23 to function as a position information acquisition unit 231, a transmission unit 232, a reception unit 233, and a correction unit 234.

The control unit 23 is, for example, a CPU. The control unit 23 functions as a position information acquisition unit 231, a transmission unit 232, a reception unit 233, and a correction unit 234 by executing a program stored in the storage unit 22.

The location information acquisition unit 231 acquires device location information indicating the location of the target device 2. For example, first, a receiving unit (not shown) provided in the target device 2 that receives radio waves from GNSS satellites receives radio waves transmitted from a plurality of GNSS satellites at predetermined intervals. The position information acquisition unit 231 measures the distance between each of the plurality of GNSS satellites and the target device 2 based on the time from when the radio wave is transmitted from the GNSS satellite until the reception unit receives the radio wave. The position information acquisition unit 231 calculates the position of the target device 2 based on the distance between each of the plurality of GNSS satellites and the target device 2, and acquires device position information indicating the position.

Note that the location information acquisition unit 231 uses the radio field intensity of radio waves received by the communication unit 21 from a wireless LAN base station or a mobile phone line base station and the position of the wireless LAN base station or mobile phone line base station. Based on this, the position of the target device 2 may be calculated, and device position information indicating the position may be acquired. Additionally, the location information acquisition unit 231 transmits device location information indicating the location of the target device 2 calculated on the base station side based on the radio field strength of the radio waves received from the target device 2 by these plurality of base stations to the communication unit 21. The device location information may be acquired by receiving the device location information via the .

The transmitter 232 transmits the device location information acquired by the location information acquirer 231 and authentication information that is used for authentication of positioning in the positioning service and includes device information indicating the target device 2 to the information processing device 1 . For example, the storage unit 22 stores authentication information and address information indicating the address of the information processing device 1 in advance. The transmitting unit 232 acquires the authentication information and the address information of the information processing device 1 stored in the storage unit 22 in addition to the equipment position information acquired by the position information acquiring unit 231. The transmitter 232 transmits a correction information acquisition request including the device location information and the authentication information to the information processing device 1 indicated by the address information via the user terminal 3. The transmitter 232 transmits the device location information and the authentication information to the information processing device 1 using a predetermined protocol, NTRIP (Networked Transport of RTCM via Internet Protocol).

The authentication information includes a user ID for identifying the user of the target device 2 in the positioning service, a password used to authenticate the user in the server 4, and device information of the target device 2.

Note that the authentication information and the address information of the information processing device 1 may be stored in the user terminal 3. In this case, the transmitter 232 transmits the device location information to the user terminal 3. Then, the user terminal 3 transfers the device location information received from the target device 2 and the authentication information stored therein to the information processing device 1 based on the address information of the information processing device 1 stored therein. You may also send it to

The receiving unit 233 receives correction information provided from the server 4 from the information processing device 1 . For example, after the information processing device 1 determines that the device location information is to be transmitted to the server 4 and the device location information is transmitted to the server 4, the receiving unit 233 transmits the device location information to the server 4 via the user terminal 3 and the information processing device 1. Receive correction information provided by. The receiving unit 233 receives the correction information from the information processing device 1 using NTRIP, which is a predetermined protocol.

The correction unit 234 corrects the position indicated by the device position information acquired by the position information acquisition unit 231 based on the correction information received by the reception unit 233. Thereby, the target device 2 can correct the position indicated by the device position information to a highly accurate position. The correction unit 234 may transmit corrected position information, which is corrected device position information, to the user terminal 3.

[Operation of each part of the control unit 13]
Next, the operation of each part of the control section 13 will be explained. The control unit 13 executes a process of registering condition information in the storage unit 12, a process of relaying communication between the target device 2 and the server 4, and a process of determining usage fees for use of the positioning service by the user. Below, these processes will be explained in order.

[Register condition information]
First, the process of registering condition information in the storage unit 12 will be described. The registration unit 131 accepts registration or update of condition information. For example, the registration unit 131 receives a request to register condition information from an administrator terminal (not shown) used by an administrator who manages whether or not to transmit device location information to the server 4. The registration request includes device information corresponding to the target device 2 for which transmission of device location information to the server 4 is permitted. The device information included in the registration request is the device information specified by the operator providing the positioning service, or the device information received in advance from the user of the positioning service and corresponding to the target device 2 used by the user for the positioning service. It may be. Upon receiving a registration request for condition information, the registration section 131 causes the storage section 12 to store the device information included in the registration request as condition information. Further, the registration unit 131 receives updates of the condition information stored in the storage unit 12.

[Relay of communication between target device 2 and server 4]
Next, the functions of the control unit 13 related to relaying communication between the target device 2 and the server 4 will be explained. By working together, the location information receiving section 132, the determining section 133, the location information transmitting section 134, the correction information receiving section 135, and the correction information transmitting section 136 function as a reverse proxy when the target device 2 accesses the server 4. It functions and filters communication between the target device 2 and the server 4.

Further, the position information receiving unit 132, the position information transmitting unit 134, the correction information receiving unit 135, and the correction information transmitting unit 136 transmit and receive information using NTRIP, which is a predetermined protocol. Hereinafter, the details of the functions of the position information receiving section 132, the determining section 133, the position information transmitting section 134, the correction information receiving section 135, and the correction information transmitting section 136 will be described.

The location information receiving unit 132 is used for authentication of the target device in a positioning service that provides device location information indicating the position of the target device 2 and correction information for correcting the position from the target device 2 that is the target of positioning. and authentication information including device information indicating the target device. For example, the location information receiving unit 132 receives a correction information acquisition request including the device location information and authentication information from the target device 2 via the user terminal 3, thereby acquiring the device location information and authentication information. Receive. By acquiring a correction information acquisition request, the position information receiving unit 132 can receive a set of device position information and authentication information at the same timing.

Based on the authentication information received from the target device 2, the determination unit 133 determines whether to transmit the device location information to the server 4 that provides the positioning service. The determination unit 133 determines the determination based on at least one of the model of the target device 2, the type of the target device 2, the serial number of the target device 2, and software information, which are device information included in the authentication information received from the target device 2. Then, it is determined whether or not to transmit the device location information to the server 4.

Specifically, the determination unit 133 refers to the condition information stored in the storage unit 12 that indicates device information corresponding to the target device 2 for which transmission of correction information is permitted, and determines the authentication information received from the target device 2. It is determined whether condition information matching the combination of the model of the target device 2, the device type of the target device 2, the serial number of the target device 2, and software information, which are the device information included in the target device 2, is stored. If the determination unit 133 determines that matching condition information is stored, it determines to send the device location information to the server 4, and if it determines that matching condition information is not stored, it transmits the device location information to the server 4. Determine not to send.

For example, the model of target device 2 included in the device information included in the authentication information received from target device 2 is "A," the device type of target device 2 is "drone," and the serial number of target device 2 is " PKMMN", and the software used for positioning in target device 2 is "x". In the example shown in FIG. 3, if the device type is "drone", the model is "A", and the serial number is "PKMMN", there are no restrictions on the software used for positioning in target device 2. The determining unit 133 determines that condition information that matches the combination of the model of the target device 2, the type of device of the target device 2, the serial number of the target device 2, and the software information included in the received device information is stored. Then, it is determined that the device location information is to be transmitted to the server 4. Note that in the above example, a wild card is set in the software and no restrictions are placed on the software, but a wild card may be set in the serial number. If the determination unit 133 stores condition information that matches the combination of device type and model received from the target device 2, the determination unit 133 transfers the device location information to the server 4 regardless of the received serial number and software content. You may also send it to

In addition, the model of the target device 2 included in the device information included in the authentication information received from the target device 2 is “C”, the device type of the target device 2 is “walking measurement”, and the serial number of the target device 2 is “C”. Assume that "AB827" and the software used for positioning in the target device 2 are "z". In the example shown in FIG. 3, when the type of device is "walking measurement" and the model is "C", the software used for positioning is limited to "x". Therefore, the determination unit 133 stores condition information that matches the combination of the model of the target device 2, the type of the target device 2, the serial number of the target device 2, and the software information included in the received device information. It is determined that there is no device location information, and it is determined that the device location information is not to be transmitted to the server 4.

Note that the determining unit 133 determines whether or not to transmit the device location information to the server 4 by determining whether or not the device information received from the target device 2 is stored in the condition information stored in the storage unit 12. However, it is not limited to this. The determination unit 133 may identify address information indicating the address of the target device 2 on the communication network, and determine whether or not to transmit the device location information to the server 4 based on the address information.

In this case, for example, address information that permits transmission of device location information is stored in the storage unit 12. Address information is an IP address or host name. The determining unit 133 identifies the IP address or host name assigned to the target device 2 as address information indicating the address of the target device 2 on the communication network. If the identified address information is stored in the storage unit 12, the determination unit 133 determines that the device location information is to be transmitted to the server 4, and if the address information is not stored in the storage unit 12, the determination unit 133 determines that the device location information is to be transmitted to the server 4. It is determined that the data is not sent to 4.

Further, the determination unit 133 identifies the communication carrier that the target device 2 uses for communication by referring to association information that associates the target device 2 with the communication carrier used by the target device 2, and selects the communication carrier that the target device 2 uses for communication. Based on this, it may be determined whether or not to transmit the device location information to the server 4.

The association information is, for example, information in which address information of the target device 2 and carrier information indicating a communication carrier are associated. The determination unit 133 identifies address information indicating the address of the target device 2 on the communication network, and identifies carrier information associated with the identified address information in the association information, thereby identifying the carrier information that the target device 2 uses for communication. Identify your carrier. Then, the determination unit 133 determines that the device location information is to be transmitted to the server 4 when the identified communication carrier is a communication carrier that is permitted to be used in the positioning service, and determines that the device location information is to be transmitted to the server 4 when the identified communication carrier is a communication carrier that is not permitted to be used. In some cases, it is determined that the device location information is not to be transmitted to the server 4.

By doing so, the information processing device 1 is limited to the case where the target device 2 is communicating using a predetermined communication network or a predetermined communication carrier that is specified for use in the positioning service. Since the device location information can be transmitted to the server 4, the load on the server 4 can be reduced. Furthermore, since the information processing device 1 transmits the device location information to the server 4 only when the target device 2 is communicating using a predetermined communication carrier, the convenience of the predetermined communication carrier is This can increase the competitive advantage of a given communication carrier.

Further, the determination unit 133 may determine whether or not to transmit the device position information to the server 4 based on the amount of change in position indicated by the device position information received from the target device 2 at a plurality of different times. In this case, the location information receiving unit 132 receives the device location information from the target device 2 at predetermined time intervals, thereby receiving the device location information at a plurality of different times.

The determination unit 133 determines whether to transmit the device position information to the server 4 based on the amount of change in position indicated by each of the plurality of device position information received from the target device 2 within a predetermined time. For example, the determination unit 133 determines that the device position information is to be transmitted to the server 4 when the amount of change in the position indicated by each of the plurality of device position information exceeds a predetermined threshold, and determines that the device position information is to be transmitted to the server 4 when the amount of change in the position indicated by each of the plurality of device position information exceeds a predetermined threshold. It is determined that the position information is not to be transmitted to the server 4. By doing this, for example, when the amount of movement of the target device 2 is small or when the target device 2 is not moving, it is possible to prevent the device position information from being sent to the server 4. The load can be reduced.

When the determining unit 133 determines to transmit the device position information to the server 4, the position information transmitting unit 134 transmits the received device position information to the server 4. For example, when the determining unit 133 determines to transmit the device position information to the server 4, the location information transmitting unit 134 receives the user ID and password included in the authentication information included in the correction information acquisition request, together with the authentication information. The device location information is sent to the server 4.

Upon receiving the device location information, user ID, and password from the information processing device 1, the server 4 authenticates whether the user is a user who uses the positioning service based on the received user ID and password. When the server 4 successfully authenticates the user, the server 4 specifies the electronic reference point 5 provided near the position indicated by the received device position information. Then, the server 4 generates correction information for correcting the position of the target device 2 indicated by the device position information based on the position observed at the specified electronic reference point 5, and transmits the correction information to the information processing device 1. Send to. The server 4 transmits the correction information to the server 4 using the same protocol (NTRIP) used when receiving the device location information. Note that the method for generating the correction information is a well-known technique, so a detailed explanation will be omitted.

After the location information transmitting section 134 transmits the user ID, password, and device location information to the server 4, the correction information receiving section 135 receives correction information corresponding to the device location information from the server 4.

The correction information transmitter 136 transmits the received correction information to the target device 2. For example, in response to the correction information receiving unit 135 receiving the correction information from the server 4, the correction information transmitting unit 136 sends a message to the target device 2 that is the source of the correction information acquisition request via the user terminal 3. Send correction information.

[Determination of usage fees for use of positioning services]
Next, the functions of the control unit 13 related to determining the usage fee for the use of the positioning service will be explained. The determining unit 137 determines a usage fee to be charged to the user of the target device 2 in response to the user using the positioning service.

For example, the determining unit 137 specifies the usage form of the positioning service based on the amount of change in position indicated by each of the plurality of device position information received from the target device 2. For example, when the amount of change in the position indicated by each of the plurality of device position information received from the target device 2 is less than the first threshold, the determining unit 137 specifies the usage mode of the positioning service as usage on foot. When the amount of change in position indicated by each of the plurality of pieces of device position information is greater than or equal to the second threshold, the determining unit 137 specifies that the usage form of the positioning service is usage by a mobile object. Further, if the amount of change in the position indicated by each of the plurality of device position information is greater than or equal to the first threshold and less than the second threshold, the determining unit 137 performs positioning service on foot or by a mobile object such as a drone or a vehicle. Since it is thought that the positioning service is used, the usage pattern of the positioning service is specified as walking and mobile usage.

The determining unit 137 determines the usage fee to be charged to the user of the target device 2 for using the positioning service based on the specified usage pattern. For example, the storage unit 22 stores a fee table showing usage fees for each usage type. For example, when the usage type is a mobile object such as an airplane, the usage time is shorter than when the usage type is on foot because there is a limit on the driving time of the mobile object, and the usage time is shorter than when the usage type is on foot. It is thought that the load on 4 is small. Therefore, the usage fee when the usage type is mobile use is lower than the usage fee when the usage type is mobile use and walking use, and the usage fee when the usage type is walking use. set to a low amount. The determining unit 137 determines the usage fee by referring to the fee table and identifying the usage fee corresponding to the specified usage type. By doing so, the information processing device 1 can make it possible to pay appropriate fees according to the type of equipment used, etc., and can encourage users to use the device in a manner that maximizes usage efficiency. .

Note that although the determining unit 137 determines the usage fee to be charged to the user based on the usage type of the positioning service, the present invention is not limited thereto. The determining unit 137 may determine the usage fee to be charged to the user of the target device 2 for using the positioning service based on the frequency of receiving device location information from the target device 2 during a predetermined period. For example, the determining unit 137 may determine the usage fee such that the higher the frequency of receiving the device location information from the target device 2, the higher the usage fee charged to the user. By doing so, for example, a user who uses the positioning service infrequently can easily use the positioning service.

[Operation sequence]
Next, the flow of processing in the positioning system S will be explained. FIG. 5 is a sequence diagram showing the flow of processing for correcting device position information in the positioning system S.
First, the location information acquisition unit 231 of the target device 2 acquires device location information indicating the location of the target device 2 (S1).
Subsequently, the transmitting unit 232 acquires the authentication information stored in the storage unit 22, and transmits the acquired device position information and authentication information to the information processing device 1 (S2). The location information receiving unit 132 of the information processing device 1 receives device location information and authentication information from the target device 2. The authentication information includes device information indicating the target device 2, the user ID of the user of the target device 2, and a password.

Subsequently, the determination unit 133 of the information processing device 1 performs a transmission determination process to determine whether to transmit the device location information to the server 4 that provides the positioning service based on the authentication information received from the target device 2 (S3 ). When the determination unit 133 of the information processing device 1 determines to send the device location information to the server 4 in S3, the determination unit 133 sends the user ID and password included in the received authentication information and the device location information received together with the authentication information. It is transmitted to server 4 (S4).

When the server 4 receives the user ID, password, and device location information from the information processing device 1, it performs authentication processing based on the received user ID and password (S5). The server 4 generates correction information corresponding to the received device position information in response to the successful user authentication in S5 (S6), and transmits the correction information to the information processing device 1.

The correction information receiving unit 135 of the information processing device 1 receives correction information from the server 4 (S7). When the correction information receiving unit 135 receives the correction information, the correction information transmitting unit 136 transmits the correction information to the target device 2 that is the source of the device location information and authentication information (S8).

Upon receiving the correction information provided from the server 4 from the information processing device 1, the receiving unit 233 of the target device 2 corrects the position indicated by the device position information acquired in S1 based on the received correction information (S9 ).

[Modification 1]
In the above-described embodiment, the location information receiving unit 132 receives the device location information and authentication information at once by receiving a correction information acquisition request including the device location information and authentication information. Not exclusively. The location information receiving unit 132 may receive a request to obtain correction information that includes only authentication information. For example, the location information receiving unit 132 receives a correction information acquisition request that includes device location information and authentication information once every 5 seconds, and receives a request that only includes authentication information once every 1 second. A correction information acquisition request may also be received. In this case, when the determination unit 133 determines to transmit the device location information to the server 4, the location information transmitter 134 may transmit the last received device location information to the server 4. By doing so, the target device 2 can reduce the number of times the device position information is calculated, so the load on the target device 2 can be reduced.

[Modification 2]
Further, in the above embodiment, the target device 2 corrects the position indicated by the device position information, but the present invention is not limited to this, and a device different from the target device 2 corrects the position indicated by the device position information. Good too. For example, in response to receiving the correction information from the server 4, the information processing device 1 or the user terminal 3 corrects the position indicated by the device position information received from the target device 2, and the corrected position indicates the corrected position. The information may be transmitted to the target device 2. Further, the server 4 may correct the position indicated by the device position information received from the information processing apparatus 1 based on the generated correction information, and may transmit the corrected position information to the information processing apparatus 1.

[Modification 3]
Further, in the embodiment described above, the condition information is stored in the storage unit 12, and the determination unit 133 refers to the condition information stored in the storage unit 12 to determine the device position information received from the target device 2. Although it has been determined whether or not to transmit to the server 4, the present invention is not limited to this. For example, the condition information may be stored in the server 4, and the determination unit 133 may determine whether or not to transmit the device position information received from the target device 2 to the server 4.

[Modification 4]
Further, in the embodiment described above, the determining unit 137 determines the usage fee by referring to the fee table stored in the storage unit 12 and identifying the usage fee corresponding to the specified usage type. It is not limited to this. For example, a fee determination server that determines a fee is provided separately from the information processing device 1, and the determination unit 137 transmits a usage fee determination request including the specified usage fee to the fee determination server, and determines the fee. The usage fee may be determined by having the server determine the usage fee. Further, the determining unit 137 may not determine the fee. For example, the determining unit 137 determines the usage fee for the user corresponding to the user ID by providing the user ID included in the authentication information and information indicating the specified usage pattern to an external device such as a fee determination server. It is also possible to entrust this to an external device.

Further, the determining unit 137 transmits a usage fee determination request including the reception frequency of device location information from the target device 2 during a predetermined period to the fee determination server, and causes the fee determination server to determine the usage fee. may be determined. Further, in this case, the server 4 may function as a fee determination server.

[Modification 5]
Further, in the above-described embodiment, the information processing device 1 receives device location information indicating the location of the target device and authentication information from the target device 2 via the user terminal 3 connected to the target device 2. Although the correction information is received and transmitted to the target device 2 via the user terminal 3, the present invention is not limited thereto. The information processing device 1 directly receives device location information and authentication information from the target device 2 without going through the user terminal 3, and transmits the correction information received from the server 4 to the target device without going through the user terminal 3. You can also send it directly to 2.

[Effects of information processing device 1]
As explained above, the information processing device 1 according to the present embodiment receives device position information indicating the position of the target device 2 and correction information for correcting the position from the target device 2 that is the target for positioning. It receives authentication information that is used to authenticate the target device 2 in the provided service and includes device information indicating the target device 2, and transmits device location information to the server 4 that provides the service based on the received authentication information. Determine whether When the information processing device 1 determines to transmit the device location information to the server 4, it transmits the received device location information to the server 4, receives correction information corresponding to the device location information from the server 4, and uses the received correction information. Send to target device 2. By doing so, the information processing device 1 can reduce the load on the server that implements the positioning service.

Furthermore, the present invention makes it possible to contribute to Goal 9 of the Sustainable Development Goals (SDGs) led by the United Nations, "Create a foundation for industry and technological innovation."
