Description

  The present invention relates to a mobile communication terminal that enables a charging process for use of a paid facility in which movement by a vehicle is limited to an allowable area.

  In a billing system such as ETC (Electronic Toll Collection System), entrance information that can identify the location where the vehicle has entered when entering a toll facility (for example, an expressway) where movement by vehicle is limited to an allowable area When the user exits the paid facility, the charge processing for the use of the paid facility is performed based on the entrance information. At that time, as far as ETC is concerned, entrance information is stored in the ETC card when the vehicle enters the entrance gate of a toll road such as a highway, and the entrance information is charged and erased when passing through the exit gate. .

  However, there is a problem that the ETC card is taken out of the highway while valid entrance information is stored and fraud such as a fraud fraud is performed.

  On the other hand, in recent years, a technique using a mobile phone instead of an ETC card is known (see, for example, Patent Document 1), but even in an ETC system using such a mobile phone, entrance information remains stored and high speed is achieved. A similar problem can be considered that the vehicle is taken out of the tolerable area of a toll road such as a road.

  Conventionally, in order to prevent such a problem, a method of determining that the reliability of the entrance information is low when a predetermined time or more has passed since the date and time when the entrance gate was entered.

JP 2000000811849 A

  However, according to such a conventional method, when taking a break in a paid facility or spending time in an amusement facility, it takes more time than usual even though no fraud has been done. There is a problem that fraud is suspected when leaving. Further, since it is attempted to detect fraud only with time information, there remains a problem that cannot be detected when fraud is performed within a predetermined time.

  The present invention has been made to solve these problems, and an object of the present invention is to provide a mobile communication terminal and a charging management system that can accurately determine the reliability of entrance information.

  The invention according to claim 1, which has been made to achieve the above object, acquires entrance information that can specify the position where the vehicle has entered when entering a paid facility whose movement by a vehicle is limited to an allowable area, and the paid facility. Is a mobile communication terminal that enables billing processing for the use of the toll facility based on the entrance information, and includes detection means and determination means. The detecting means detects that the mobile communication terminal is outside the allowable area of the paid facility, and the determining means detects the entrance information when the detecting means detects that the mobile communication terminal is outside the allowable area of the paid facility. It is determined that the reliability of is low.

  According to the invention described in claim 1, it is detected that a mobile communication terminal that is not originally taken out of the tolerable area of the pay facility unless it is charged is outside the tolerable area of the pay facility. Thus, since it is determined that the reliability of the entrance information is low, the reliability of the entrance information can be accurately determined.

  By the way, even if it is detected that it is outside the allowable area, it may actually exist continuously in the allowable area of the toll facility due to communication circumstances or the like.

  Therefore, the invention according to claim 2 is the mobile communication terminal according to claim 1, wherein the determination means is provided when the detection means detects that the mobile communication terminal is outside the allowable area of the pay facility for a predetermined time or more. It is determined that the reliability of information is low.

  According to the invention described in claim 2, since it is determined that the reliability of the entrance information is low when it is detected that it is out of the permissible area of the toll facility for a predetermined time or more, it is only for a short period due to the communication situation or the like. If it is detected that it is outside the permissible area of the paid facility, it will be excluded and a reliable determination will be possible.

  In addition, if an accurate current position of the mobile communication terminal can be acquired, it is desirable that a more accurate determination of reliability can be made.

  Accordingly, a third aspect of the present invention is the mobile communication terminal according to the first or second aspect, further comprising an acquisition unit, and the acquisition unit acquires a current position of the mobile communication terminal by a GPS satellite system. Then, the detecting means detects that the mobile communication terminal is outside the allowable area of the pay facility based on the current position acquired by the acquiring means.

  According to the third aspect of the present invention, since the current position of the mobile communication terminal is acquired by the GPS satellite system and it is detected that it is outside the allowable area of the toll facility, the entrance information is accurately determined based on the accurate position. Can be determined.

  Furthermore, the acquisition of the current position by the GPS satellite system is not always the case when the accuracy is high.

  Therefore, the invention according to claim 4 is the mobile communication terminal according to claim 3, wherein the mobile communication terminal determines that the accuracy of the current position acquired by the acquisition means is low. Do not detect that you are outside the area.

  According to the invention described in claim 4, when the accuracy of the current position is low, since it is not detected that the mobile communication terminal is outside the allowable area of the pay facility, it is erroneously determined that the reliability is low. You can avoid that.

  Further, since the location of the base station of the mobile phone is fixed, it can be easily detected that the base station is within the permissible area as long as it is a base station that covers the permissible area of the pay facility.

  Accordingly, the invention described in claim 5 is a billing management system including the mobile communication terminal according to any one of claims 1 to 4 and a base station that performs radio communication with the mobile communication terminal. The base station is provided with a flag transmission unit, and the flag transmission unit covers the permissible area of the pay facility in one or a plurality of areas, and can be received by a mobile communication terminal in the one or a plurality of areas. Send flag with status. The detecting means detects that the mobile communication terminal is outside the tolerable area of the toll facility when the flag transmitted from the base station cannot be received.

  According to the invention of claim 5, since it is determined that the flag transmitted from the base station that covers the allowable area of the pay facility cannot be received, it is determined that the vehicle is outside the allowable area. The reliability of entrance information can be determined.

  Furthermore, it is possible to make a more accurate determination by detecting whether the mobile communication terminal is outside or within the allowable area from the relationship between the position and direction of the base station using the current position obtained by the GPS system. Become.

  Accordingly, the invention described in claim 6 is a billing management system including the mobile communication terminal according to claim 3 or claim 4 and a base station that performs radio communication with the mobile communication terminal. The base station includes a direction transmission unit, and the direction transmission unit transmits the position of the base station and the direction where the allowable area of the pay facility exists to the mobile communication terminal. The detecting means detects that the mobile communication terminal is outside the tolerable area of the toll facility based on the direction in which the tolerable area of the toll facility exists from the base station and the current position acquired by the acquiring means.

  According to the invention described in claim 6, since it is determined that the mobile communication terminal is outside the allowable area of the toll facility based on the direction of the allowable area and the current position transmitted from the base station, Judgment is possible.

  By the way, if the travel route after entering the paid facility is stored, it is possible to make the same determination as in claim 1.

  Therefore, the invention according to claim 7 obtains entrance information that can specify the position where the vehicle has entered when entering the toll facility, in which movement by the vehicle is limited to the permissible area, and when exiting the toll facility, the entrance A billing management system that performs billing processing by communicating with a mobile communication terminal that enables billing processing for use of the toll facility based on information, and includes a storage unit route, an acquisition unit, and a determination unit. The storage means stores the movement route after the mobile communication terminal enters the pay facility in the storage device, the route acquisition means acquires the movement route stored in the storage device, and the determination means acquires by the route acquisition means. When the mobile communication terminal is assumed to have left the permissible area of the toll facility based on the travel route, the entrance information is determined to be low in reliability.

  According to the invention of claim 7, since it is determined that the reliability of the entrance information is low when it is determined that the mobile communication terminal is taken out of the tolerable area of the toll facility based on the route information of the mobile communication terminal. The reliability of the entrance information is low by detecting that a mobile communication terminal that would not be taken outside the tolerable area of the toll facility is outside the tolerable area of the toll facility unless otherwise charged. Therefore, it is possible to accurately determine the reliability of the entrance information.

[1-2 Overview]
FIG. 2 is an explanatory diagram showing an outline of the accounting management system 1. As shown in the figure, the mobile phones 2a to 2c are transmitted from the base stations 5a to 5d, "cover flag", the direction of the highway 6 viewed from the base stations 5a to 5d, and the positions of the base stations 5a to 5d By receiving (latitude, longitude), it is detected that the mobile phones 2 a to 2 c are outside the allowable area of the highway 6.

  Here, the “cover flag” is a flag signal transmitted only by a base station (in this case, the base stations 5a, 5b, and 5d) that covers the area of the highway 6, and is a portable signal that is at least within an allowable area of the highway 6. The telephone (here, the mobile phone 2a) receives the “cover flag” (“ON”) (S106 in the mobile phone processing (FIG. 3) described later).

  However, simply receiving this “cover flag” does not necessarily mean that the mobile phone is in the area of the highway 6. This is because, for example, even if there is a mobile phone 2c within the reception range of the “cover flag” of the base station 5d, it may be located in a completely different direction from the highway 6.

  Therefore, the billing management system 1 takes into account the direction and position information in order to more accurately detect that the vehicle is in the area of the highway 6. Specifically, the base stations 5a to 5d also transmit the direction of the highway 6 viewed from the base stations 5a to 5d and the positions (latitude and longitude) of the base stations 5a to 5d, and the mobile phone 2a In ~ 2c, it is determined whether or not the mobile phone 2a to 2c is in the area of the highway 6 as compared with its current position (S109 of mobile phone processing (FIG. 3) described later). Accordingly, the mobile phones 2a to 2c can detect that the mobile phones 2a to 2c have been taken out of the allowable area of the highway 6.

  For example, the mobile phone 2a receives the “cover flag” from the base station 5b (“ON”), and further receives the southeast and east directions and the position of the base station 5b as directions. And since the said mobile telephone 2a is in the south from the base station 5b, it detects that it exists in the tolerance zone of the highway 6.

  The mobile phone 2b does not receive the “cover flag” from the base station 5c (“off”), and detects that the mobile phone 2b is outside the allowable area of the highway 6.

Furthermore, as described above, the mobile phone 2c receives the “cover flag” from the base station 5d (“ON”), but receives the signal with the northwest direction and the position of the base station 5d. And since the said mobile telephone 2c is not northwest seeing from the base station 5d, it detects that it is outside the permissible area of the highway 6.
[1-3 Processing]
Hereinafter, processing executed by the control unit 25 of the mobile phone 2 as the first embodiment will be described with reference to the drawings. FIG. 3 is a flowchart showing the mobile phone process executed by the control unit 25 of the mobile phone 2. The control unit 25 of the mobile phone 2 enters the toll gate at the entrance gate of the toll gate, and receives the entrance information necessary for the billing process transmitted from the roadside machine at the entrance gate via the in-vehicle device 3. This process is started.

  First, in S101, the entrance information received from the roadside machine of the entrance gate is stored, and the process proceeds to S102. This entrance information can identify the toll booth where the host vehicle has entered, and the usage fee for the expressway 6 when the host vehicle exits is determined based on the entrance information.

  In S102, the invalidation timer is set to a predetermined value (for example, 10 minutes), and the process proceeds to S103. This invalidation timer corresponds to the time when the mobile phone 2 is outside the permissible area of the highway 6, and if the mobile phone 2 is out of the permissible area for the predetermined time or more, the corresponding entrance It is determined that the reliability of information is low.

  In S103, the process waits for one minute and proceeds to S104. If this is continuously determined at short time intervals, there is a possibility that an accurate determination result may not be obtained, for example, when the host vehicle is moving. In order to detect, it is determined again at a time interval of 1 minute.

  In S104, it is determined whether or not processing (exit processing) when passing through the exit gate has been performed for the entrance information. If the exit process has been performed (S104: YES), the mobile phone process is terminated. If the exit process has not been performed (S104: NO), the process proceeds to S105. This exit processing is processing in which the mobile phone 2 is appropriately charged from the roadside device 4 at the exit gate via the vehicle-mounted device 3.

  In S105, it is determined whether or not the mobile phone 2 is within the radio wave reception range. If it is not within the radio wave reception range (S105: NO), no further determination can be made, so the process returns to S103. If it is within the radio wave reception range (S105: YES), the process proceeds to S106.

  In S106, it is determined whether or not the mobile phone 2 has received a “cover flag” from the base station. If the “cover flag” has been received (“ON”, S106: YES), the process proceeds to S107, and if the “cover flag” has not been received (“OFF”, S106: NO), it is outside the allowable area of the highway. The process proceeds to S110.

  In S107, the current position is acquired by the GPS receiver 23, and the process proceeds to S108.

  In S108, it is determined whether or not the accuracy of the current position acquired in S107 is high. If the accuracy is high (S108: YES), the process proceeds to S109. If the accuracy is not high (S108: NO), no further determination is made and the process returns to S102. As described above, due to external factors such as the positional relationship (angle and distance) between the artificial satellite for GPS and the current position, the number of artificial satellites, atmospheric conditions, indoor or outdoor, the GPS antenna 23a is used. Since the reception state changes, the GPS receiver 23 knows the accuracy of the current position based on these data.

  In S109, it is determined from the direction of the highway transmitted from the base station and the position of the base station whether the current position of the mobile phone 2 acquired in S107 is in the direction of the highway. If it is in the direction of the highway (S109: YES), the process returns to S102, and if it is not in the direction of the highway 6 (109: NO), the process proceeds to S110.

  This S109 makes it possible to detect that the mobile phone 2 is not in the direction of the expressway and is outside the allowable area of the expressway as viewed from the base station, while the “cover flag” is “on”.

  In S110, the invalidation timer is decreased by 1 minute (decremented), and the process proceeds to S111.

  In S111, it is determined whether or not the invalidation timer has become smaller than zero. If the invalidation timer is smaller than 0 (S111: YES), the process proceeds to S112, and if it is not smaller than 0 (S111: NO), the process returns to S103.

  By this S111, it can be detected that the mobile phone 2 is out of the permissible area for a predetermined time of the invalidation timer.

  In S112, the user is notified by voice or screen that the entrance information is invalidated, and the process proceeds to S113.

  The reason for notifying the user that the entrance information is invalidated in S112 is that the user is not placed in a situation where the exit gate of the toll gate collides with the open / close bar or is forced to stop suddenly.

  In S113, the entrance information stored in S101 is invalidated, and this cellular phone processing is terminated.

In S113, the invalidation timer indicates that the state in which the mobile phone 2 is determined to be “off” or that the mobile phone 2 is outside the allowable area of the highway 6 from the direction of the base station. In this case, it is assumed that the reliability of the entrance information is low and the entrance information is invalidated.
[1-4 Effects]
As described above, according to the mobile phone 2 of the charge management system 1 of the first embodiment, the mobile phone 2 that is not taken out of the highway allowable area unless otherwise charged. Since it is determined that the entrance information is outside the allowable area of the expressway for a predetermined time or more and it is determined that the reliability of the entrance information is low (S102 to S113 of the mobile phone processing), the reliability of the entrance information can be accurately determined.

  In this case, since the detection is performed for a predetermined time or longer (S103 to S111 of the mobile phone processing), the case where it is detected that it is out of the permissible area of the toll facility for a short period of time simply due to the communication situation or the like is excluded. Thus, a reliable determination is possible.

  At that time, in order to detect the current position of the mobile phone 2 by the GPS receiver 23 and detect that it is outside the permissible area of the highway (S108 and S109 of the mobile phone process), the entrance is accurately based on the accurate position. The reliability of information can be determined.

  In addition, when the accuracy of the current position is low, since it is not detected that the mobile communication terminal is outside the permissible area of the pay facility (S108 of the mobile phone process), it is erroneously determined that the reliability is low. Can be avoided.

  Furthermore, since the flag transmitted from the base station that covers the permissible area of the pay facility cannot be received, it is determined that the user is outside the permissible area (S106 of the mobile phone processing). Reliability can be determined.

In addition, since it is determined that the mobile communication terminal is outside the allowable area of the pay facility based on the direction of the allowable area transmitted from the base station and the current position (S109 of the mobile phone process), more accurate determination is possible. It becomes possible.
[1-5 Correspondence with Claims]
Note that S105 to S111 executed by the control unit 25 of the mobile phone 2 of the first embodiment are detection means, S106, S109, S111, S112, and S113 executed by the control unit 25 of the mobile phone 2 are determination means, and the mobile phone 2 S109 executed by the control unit 25 corresponds to an acquisition unit. The process in which the base station transmits a “cover flag” corresponds to the flag transmitting means, and the process in which the base station transmits the position and the direction in which the highway is located corresponds to the direction transmitting means.
[2 Second Embodiment]
A billing management system as a second embodiment will be described.

The billing management system of the second embodiment has the same hardware configuration as the billing management system of the first embodiment, but the control unit 25 of the mobile phone 2, the control unit 35 of the vehicle-mounted device 3, and the control of the roadside device 4. Only the processing executed by the unit 46 is different. Therefore, only this difference will be described, and description of other common parts will be omitted.
[2-1 Overview]
In the billing management system of the second embodiment, the mobile route after the mobile phone 2 enters the highway is stored in the mobile phone 2, and when the vehicle exits the stored travel route from the exit gate. In addition, the determination is made by roadside machine processing (FIG. 4) executed by the control unit 46 of the roadside machine 4.
[2-2 Processing]
FIG. 4 is a flowchart showing a roadside machine process executed by the control unit 46 of the roadside machine 4 of the exit gate as the second embodiment. The control unit 46 of the roadside machine 4 starts this roadside machine process by detecting that the vehicle has come before the exit gate in an attempt to leave the exit gate and starts communication with the vehicle-mounted device 3.

  First, in S201, the in-vehicle device 3 is requested for entrance information and route information, and the process proceeds to S202. Similar to the first embodiment, this entrance information is necessary for the billing process, and the route information is stored in the mobile phone 2 by the route processing (FIG. 6) described later executed by the control unit 25 of the mobile phone 2. The movement route memorize | stored is shown.

  In S202, entrance information and route information are acquired from the onboard equipment 3, and it progresses to S203.

  In S203, it is determined from the entrance information and route information acquired from the vehicle-mounted device 3 whether the travel route and the required time are valid. If this is valid (S203: YES), the process proceeds to S204, and if not valid (S203: NO), the process proceeds to S206.

  In the determination of S203, first, the date and position at the time of entry included in the entrance information is compared with the date and position at which the vehicle is about to leave, and it is determined whether it takes longer than necessary for the distance. In addition, the travel route of the mobile phone 2 is stored in advance in the mobile phone 2 after entering, and the legitimacy is determined based on whether or not the travel route goes out of the allowable area of the expressway.

  As a method of determining whether or not the movement route has gone out of the allowable area, the location where the mobile phone 2 is present is stored as route information every predetermined time (for example, 1 minute), and stored. It can be considered that the mobile phone 2 is compared with the position of the highway stored in the roadside device 4 to determine whether the mobile phone 2 has left the permissible area. Also, a method of storing the position as route information when the mobile phone 2 is determined to be outside the allowable area of the expressway in S106 and S109 of the mobile phone process of the first embodiment is also conceivable.

  Regarding the determination of required time and route information, there can be a method that is not valid only when both requirements are met, and when the time clearly outside the allowable area from the route information is long, Even if the required time is not long, it can be considered to deny the validity.

  In S204, there is no problem in the validity (when passage is permitted), the opening / closing bar is opened by the opening / closing bar control unit 44, and the process proceeds to S205.

  In S205, the signal which permits passage is transmitted with respect to the onboard equipment 3, and this roadside machine process is complete | finished.

  On the other hand, in S206, it is a case where the moving route or the required time is not valid, the process proceeds to S207 with the open / close bar kept closed.

  In S207, a signal that does not permit passage to the vehicle-mounted device 3 (a signal that does not permit passage) is transmitted, and the roadside device processing is terminated. After this, necessary measures are taken.

  FIG. 5 is a flowchart illustrating on-vehicle device processing executed by the control unit 35 of the on-vehicle device 3 according to the second embodiment. The control part 35 of the onboard equipment 3 starts this process by starting communication with the roadside machine 4 of an exit gate, before the own vehicle leaves an exit gate.

  First, in S301, the mobile phone 2 is requested to transmit entrance information and route information, and the process proceeds to S302.

  In S302, the entrance information and the route information are received from the mobile phone 2, and the process proceeds to S303.

  In S303, the entrance information and route information received in S302 are transmitted to the roadside device 4, and the process proceeds to S304.

  In S304, it is determined whether the determination result of the roadside device 4 is permitted to pass or not allowed (corresponding to S205 and S207 of the above-mentioned roadside device processing). If it is not permitted to pass (S304: disabled), the process proceeds to S305, and if permitted (S304: allowed to pass), the process proceeds to S307.

  In S305, the user is notified of the error by voice and display, and the process proceeds to S306.

  In S306, the mobile phone 2 is requested to delete the entry information in error, and this in-vehicle device processing is terminated.

  This S306 is a case where the entrance information or the route information stored in the mobile phone 2 is not determined to be valid by the roadside device 4, and for example, unnatural time has elapsed since the entrance. This is a case where the mobile phone 2 is taken out of the permissible area as seen from the movement route after entry, and the reliability of the entrance information is determined to be low.

  On the other hand, S307 is a case where the passage is permitted, requesting the mobile phone 2 to delete the input information and the route information, and requesting to write the current travel history for the billing process. OBE processing is terminated.

  FIG. 6 is a flowchart showing route processing executed by the control unit 25 of the mobile phone 2 as the second embodiment. The control unit 25 of the mobile phone 2 starts this route processing upon receiving a route information write or read command for the mobile phone 2.

  First, in S401, it is determined whether the current process is reading or writing path information. If the path information is read (S401: read), the process proceeds to S402. If the path information is written (S401: write), the process proceeds to S404.

  In S402, a request for reading entrance information and route information is received from the vehicle-mounted device 3 (corresponding to S301 of the vehicle-mounted device processing), and is stored in the storage unit 22 of the mobile phone 2 as designated information. The entrance information and route information are read, and the process proceeds to S403.

  In S403, the read entrance information and route information are transmitted to the vehicle-mounted device 3, and this route process is terminated.

  On the other hand, in S404, there is a request for writing route information. For example, a position outside the allowable area is written as the designated information, and this route processing is terminated.

This S404 is a process in which the mobile phone 2 stores the route after the host vehicle enters the entrance gate of the expressway in the storage unit 22 as route information, and any method may be adopted. In addition to the method in which the mobile phone 2 stores the location where the mobile phone 2 is present at regular time intervals (for example, 1 minute), the mobile phone 2 is connected to the expressway in S106 and S109 of the mobile phone processing of the first embodiment. A method of storing the position as route information when it is determined to be outside the allowable area is also conceivable.
[2-3 Effects]
According to the accounting management system of the second embodiment described above, the mobile phone 2 is connected to the expressway based on the route information stored in the storage unit 22 of the mobile phone 2 by the route processing executed by the control unit 25 of the mobile phone 2. When it is determined that the vehicle has been taken out of the permissible area (S203 of roadside machine processing), since the reliability of the entrance information is low, the exit from the exit gate is not permitted (S206 of roadside machine processing). It is determined that the reliability of the entrance information is low by detecting that the mobile phone 2 that would not be taken out of the tolerable area of the toll facility is outside the tolerable area of the toll facility unless it is originally charged. Therefore, the reliability of the entrance information can be accurately determined.
