<<The circumstances that led to the creation of the embodiments of the present application>>
First, the circumstances that led the inventors to create the embodiment of the present application will be explained using FIG. 1. FIG. 1 is an explanatory diagram for explaining the outline of the embodiment.

As explained earlier, toll roads such as expressways have entrance and exit gates for collecting tolls, and when a car passes through the gates, tolls are automatically collected by the ETC system. are doing. In this ETC system, tolls are automatically collected from vehicles traveling on the applicable toll road by performing short-range communication between the ETC on-vehicle device installed in the vehicle and the ETC communication device installed at the gate. . In detail, the ETC system specifies the charging start point and charging end point of the car by performing short-range communication with the gate, calculates the fee based on the information of each specified point, and automatically collects the calculated fee. do.

However, in the ETC system, not only does the installation cost of the gate and the ETC communication device increase, but also the vehicle tends to stop or pass through the gate at a slow speed. Traffic jams can easily occur in front. Therefore, there was a need for technology that could automatically collect tolls without installing gates.

Therefore, in order to automatically collect tolls without installing a gate, the present inventors installed a GNSS (Global Navigation Satellite System) receiver on a car and calculated the charge amount based on the car's positioning by the GNSS receiver. Created an embodiment. Specifically, in this embodiment, for example, a toll road 700 as shown in FIG. 1 is set with a charging start point 800a at which charging starts as a virtual gate, and a charging end point 800b at which charging ends ( Note that in the following description, the billing start point 800a and billing end point 800b are collectively referred to as billing points 800). In this embodiment, a fee corresponding to the distance L between the charging start point 800a and the charging end point 800b is automatically collected from the vehicle 600 that has passed through the charging points 800a and 800b. Note that in this specification, a charging point refers to a virtually set point that can be a starting point for charging a fee or an ending point for ending charging.

By the way, when using only position information from a GNSS receiver installed in a car (independent positioning method; one GNSS receiver simultaneously receives GNSS signals from multiple GNSS satellites and calculates the distance from each GNSS satellite) Currently, there may be an error of several meters in the position information. If the above-mentioned level of error occurs, it may be difficult to detect the passage of the vehicle 600 through the tolling point 800 (for example, an intersection or each block of a lane) as shown in FIG. be. Therefore, the present inventors came up with the idea of correcting the position information of the automobile 600 in real time by using the position information of a GNSS receiver installed in a reference station whose installation position is known in advance (such a method is called the Real Time Kinematic (RTK) positioning method). For example, by using the RTK positioning method, the error in position information can be suppressed to about several centimeters, making it easier to detect when the car 600 passes the charging point 800.

<<About RTK positioning method>>
Therefore, before explaining the details of the embodiment of the present application, an RTK positioning method that can be used in the present embodiment will be explained with reference to FIG. 2. FIG. 2 is a diagram showing an example of the basic configuration of the information processing system 10 according to each embodiment. As shown in FIG. 2, the information processing system 10 according to the present embodiment includes a mobile station (positioning unit) 100 mounted on a vehicle (mobile object) 600, a server 200, a reference station 300, and a GNSS satellite 400. can be included. Note that details of each element included in the information processing system 10 will be described in detail in each embodiment.

In the RTK positioning method, first, for example, a mobile station 100 mounted on a car 600 and a plurality of reference stations 300 whose exact installation positions are known receive a GNSS signal from a GNSS satellite 400, and the received GNSS signal. Acquires own location information based on each. Next, the mobile station 100 mounted on the vehicle 600 whose position is to be determined transmits its own position information (hereinafter also referred to as provisional position information) obtained based on the GNSS signal to the server 200. Based on the transmitted provisional position information of the mobile station 100, the server 200 receives GNSS signals from a plurality of reference stations 300 located near the vehicle 600 (more specifically, the mobile station 100). The obtained positional information of the reference station 300 is acquired in real time.

Next, the server 200 combines the known accurate position information of the reference station 300 (for example, stored in the server 200 in advance) and the position information obtained from the reference station 300 based on the GNSS signal. Correction information is generated by calculating the difference. The correction information will be used when correcting in real time the provisional position information of the mobile station 100 obtained based on the GNSS signal. That is, in the RTK positioning method, position information (obtained based on the GNSS signal) of the reference station 300 located in a reception environment estimated to be close to the reception environment of the GNSS signal at the mobile station 100 whose position is to be determined is used. The temporary location information of the mobile station 100 obtained based on the GNSS signal is corrected using the correction information generated based on the correct location information (accurate location information, accurate location information). According to such an RTK positioning method, by performing the above-mentioned correction, it is possible to correct errors caused by ionospheric disturbances, multipath, clock deviation, etc. that occur in GNSS signals. The error contained in the information can be suppressed to about a few centimeters. As a result, according to the RTK positioning method, it becomes easy to obtain position information of the car 600 (mobile station 100) with little error, and furthermore, from the position information with little error obtained in this way, the position information of the car 600 (mobile station 100) can be easily obtained. It becomes easy to detect the passing of a tolling point 800 (for example, an intersection, each lane block, etc.). Note that in the RTK positioning method that can be used in this embodiment, it is preferable that at least two or more reference stations 300 are installed around the vehicle 600 (specifically, the mobile station 100), and further, It is preferable that the plurality of reference stations 300 be installed such that the distance between the automobile 600 (mobile station 100) and about two to five reference stations 300 is within 10 kilometers.

Furthermore, in the RTK positioning method, the server 200 or the mobile station 100 uses the correction information generated by the server 200 to correct the provisional position information of the mobile station 100 obtained based on the GNSS signal. By doing so, position information of the automobile 600 with few errors is obtained. More specifically, the RTK positioning method can be mainly divided into two methods: a device RTK positioning method in which the mobile station 100 performs the above correction, and a server RTK positioning method in which the server 200 performs the above correction.

In each of the embodiments described below, positioning using GNSS signals is used, but for example, the relative positioning of the mobile station 100 is It is also possible to use a positioning system that detects positional relationships (for example, a positioning system that uses Mobility Management Entity; MME). Furthermore, although each embodiment will be described as using the RTK positioning method, it is also possible to use other methods of GNSS positioning. Examples of other methods include an independent positioning method, a relative positioning method, and a differential positioning method.

<Information processing>
Next, information processing by the information processing system 10 according to this embodiment will be described using FIG. 11. FIG. 11 is a sequence diagram showing an example of information processing according to this embodiment. The information processing according to this embodiment includes a plurality of steps from step S201 to step S219, as shown in FIG. The details of each step will be explained below.

Steps S201 to S210 shown in FIG. 11 are the same as steps S101 to S110 of the information processing according to the first embodiment shown in FIG. 8, so the description of steps S201 to S210 will be omitted here.

In this embodiment, the server 200a, based on the difference between the location information of the installation location of each reference station 300 stored in advance in the storage unit 260 and the location information (second location information) received from the reference station 300, Correction information for correcting the temporary position information of the vehicle 600 is generated (step S211).

As described above, according to this embodiment, like the first embodiment, tolls can be automatically collected without providing a gate. As a result, according to the present embodiment, it is possible to suppress an increase in costs for environmental maintenance due to the installation of gates and ETC communication devices. Furthermore, according to this embodiment, it is possible to avoid congestion in front of the gate due to toll collection.

Further, in this embodiment, as in the first embodiment, the charging start point 800a at which charging starts and the charging end point 800b at which charging ends can be flexibly set, so a more flexible charging system can be created. It can be provided to drivers etc. Furthermore, in this embodiment, since positional information of the automobile 600 can be acquired in real time and with little error, it is possible to accurately charge the driver instantly.

Furthermore, according to the present embodiment, by employing the server RTK method, correction processing can be performed by the server 200a instead of the mobile station 100a, reducing the processing load on the mobile station 100a, and further reducing the size of the mobile station 100a. This makes it possible to reduce power consumption and reduce power consumption.

<<Third embodiment>>
As explained above, the present application is not limited to the use of RTK positioning using GNSS signals as in the first and second embodiments, but for example, positioning using MME. It is also possible to use a positioning system that detects the relative positional relationship of the mobile station 100 by communicating with a wireless base station, such as a wireless base station.

Specifically, in the RTK method described above, the reference station 300 whose location information is used when generating correction information is located closer to the mobile station 100 whose location information is to be corrected with the correction information. The more the error included in the corrected position information obtained by correction can be reduced. Therefore, the server 200 selects a reference station 300 close to the mobile station 100 based on the location information of the mobile station 100, and transmits a location information distribution request to the selected reference station 300. For example, when the mobile station 100 is mounted on a moving automobile 600, the position of the mobile station 100 changes every moment as the automobile 600 moves, and therefore the reference station 300 near the mobile station 100 also changes. Therefore, the server 200 periodically acquires the location information of the mobile station 100, selects a reference station 300 that is close to the mobile station 100 at each point in time according to the ever-changing location information, and A delivery request will be sent. As a result, the server 200 constantly repeats acquisition of location information and distribution requests, which means processing tens of thousands of tasks or more per unit time, resulting in a very large load on the server 200 and the network. It is conceivable that there may be cases where this occurs.

Therefore, in the third embodiment of the present application described below, in order to reduce the load on the server 200 and the network, the mobile station 100 uses a wireless communication system compliant with, for example, LTE (Long Term Evolution) and LTE-Advanced. If the mobile station 100 can be connected to, the mobile station 100 acquires location information from the wireless communication system based on information managed by the MME or the like. In the mobile communication system, in order to establish a communication connection or hand over a communication connection once established, the MME provides information on the relative positional relationship of the mobile station 100 to a wireless base station (not shown). Managed. Therefore, the server 200 acquires from the MME the location information of the mobile station 100 at the time of an event such as the mobile station 100 establishing a communication connection via a wireless base station or handing over to the next wireless base station. Can be done. By doing so, in the present embodiment, the server 200 can acquire the location information of the mobile station 100 from the MME without periodically acquiring the location information from the mobile station 100. It is possible to select reference stations 300 close to 100 and transmit a distribution request to the selected reference stations 300. Therefore, according to the present embodiment, the server 200 does not constantly repeat the acquisition of location information and the request for distribution, and therefore can avoid processing tens of thousands of tasks or more per unit time. As a result, according to this embodiment, it is possible to avoid an extremely large load on the server 200 and the network.

<Overview of wireless communication system>
First, an overview of the wireless communication system 20 according to this embodiment will be explained with reference to FIG. 12. FIG. 12 is an explanatory diagram for explaining an overview of the wireless communication system according to this embodiment. As shown in FIG. 12, the wireless communication system 20 according to this embodiment includes wireless base stations 580a and 580b that perform wireless communication with the mobile station 100b (see FIG. 13), and an MME 570 that performs communication management. Note that the actual wireless communication system 20 also includes a Home Subscriber Server (HSS) that has a database for managing location information of the mobile station 100b, various gateways that perform interface functions and relay, etc., but for the sake of clarity, Illustrations are omitted.

In the wireless communication system 20, as shown in FIG. 12, each wireless base station 580 is allocated an area called a cell 590, and covers communication with the mobile station 100b located within each cell 590 ( Note that each wireless base station 580 may be assigned a plurality of cells 590). Each cell 590 is also assigned a physical cell identifier (PCI). For example, when the mobile station 100b moves from the cell 590a to the cell 590b, the wireless communication system 20 performs handover in order to maintain the communication connection established with the wireless base station 580a with the next wireless base station 580b. Identification for communication connection is performed using the PCI of the cell 590b corresponding to the previous wireless base station 580b. Therefore, the MME 570 that performs communication management manages the PCI of the cell 590 corresponding to the wireless base station 580 to which the mobile station 100b connects.

Therefore, in this embodiment, the server 200b (see FIG. 13) acquires the PCI of the cell 590 corresponding to the radio base station 580 to which the mobile station 100b connects from the MME 570, and By selecting the reference station 300, it is possible to select a reference station 300 that is close to the mobile station 100b. Note that in this embodiment, the server 200b only needs to acquire the PCI when the mobile station 100 establishes a communication connection with the wireless base station 580 and when a handover occurs. This can prevent the load on the network from becoming extremely large.

<Configuration of information processing system>
