(First embodiment)
FIG. 1 shows an outline of a mobile communication system 12 according to the first embodiment. The mobile communication system 12 according to the present embodiment provides an environment in which a taxi T that is a mobile body can be connected to the Internet IN. As shown in FIG. 1, the mobile communication system 12 includes an in-vehicle communication device 10 that is a communication device connectable to the external communication network 20, and a plurality of business terminals 32 connected to the in-vehicle communication device 10. It is configured to include. The external communication network 20 is a public line network provided by a communication carrier. The in-vehicle communication device 10 and the plurality of business terminals 32 are installed in the taxi T.

  Although the communication speed between the in-vehicle communication device 10 and the external communication network 20 depends on a contract with a communication carrier, an example is as follows. For example, the communication speed is normally set to a maximum of 100 Mbps at the time of reception, a maximum of 50 Mbps at the time of transmission, etc. However, if the communication volume in the current month exceeds 7 GB, the communication speed until the end of the current month is limited to a maximum of 128 kbps at the time of transmission / reception Is done.

  The business terminal 32 of this embodiment includes a taximeter 40, a payment terminal 42, an in-vehicle printer 44, and a dispatch system 46. The in-vehicle communication device 10 and each business terminal 32 are connected by a communication interface such as a wired LAN, a wireless LAN, a USB (Universal Serial Bus), RS-232C, and Bluetooth (registered trademark).

  The taxi meter 40 is a fare meter that calculates a fare charged to passengers who use the taxi T. This taximeter 40 calculates a fare according to the boarding time and the travel distance. As shown in FIG. 3, the taximeter 40 is provided with a display unit 40 </ b> A and a selection switch 40 </ b> B on the front surface. The selection switch 40B includes an empty vehicle button 40B1, an actual vehicle button 40B2, and a payment button 40B3.

  In addition, the taximeter 40 of the present embodiment has a function of outputting information related to the business status of “empty vehicle”, “actual vehicle”, and “payment” to the in-vehicle communication device 10. Here, “empty car” is a business situation in which no passenger is in taxi T, “actual car” is a business situation in which passengers are being transported, and “payment” is a taxi T in which passengers get on. This is the business situation during the fare adjustment. These business conditions in the taximeter 40 are set by the crew of the taxi T operating each selection switch 40B.

  The settlement terminal 42 is a PINPAD terminal that is linked to the taximeter 40. That is, the settlement terminal 42 performs settlement other than cash, such as credit, debit, and electronic money. Therefore, the settlement terminal 42 is a magnetic card reader capable of reading a magnetic card, an IC card reader capable of reading a contact IC card, and a non-contact capable of reading and writing a non-contact IC card. A reader / writer is provided.

The in-vehicle printer 44 is a thermal printer for issuing a receipt when a fare is received.
In FIG. 1, each of the taximeter 40, the payment terminal 42, and the in-vehicle printer 44 is connected to the in-vehicle communication device 10. For example, the taximeter 40 and the in-vehicle printer 44 are connected to the payment terminal 42. The settlement terminal 42 may be connected to the in-vehicle communication device 10.
The dispatch system 46 is a system for dispatching a taxi T based on user arrangements, and includes a car navigation system.

  The business terminal 32 is not limited to the taximeter 40, the payment terminal 42, the in-vehicle printer 44, and the vehicle allocation system 46. For example, the business terminal 32 may include an ETC on-vehicle device, a drive recorder, a tablet-type advertisement monitor, and the like.

  On the other hand, as shown in FIG. 1, the in-vehicle communication device 10 is configured such that a smartphone 50 and a tablet terminal 52 that are personal terminals 34 can be connected via a wireless LAN. The in-vehicle communication device 10 and the personal terminal 34 may be connected via a communication interface such as USB or Bluetooth (registered trademark). Further, the personal terminal 34 connected to the in-vehicle communication device 10 is not limited to the smartphone 50 and the tablet terminal 52 but may be a personal computer, a portable game machine, or the like.

  The sales terminal 32 and the personal terminal 34 configured as described above constitute the communication terminal 30.

FIG. 2 is a functional block diagram of the in-vehicle communication device 10. As shown in FIG. 2, the in-vehicle communication device 10 includes an external communication unit 100, an internal communication unit 110, and a control unit 120.
The external communication unit 100 has a function of performing wireless communication with the external communication network 20.

  The internal communication unit 110 has a function of communicating with the communication terminal 30 used in the taxi T. The internal communication unit 110 of this embodiment includes a business terminal communication unit 112 and a personal terminal communication unit 114. The sales terminal communication unit 112 has a function of communicating with the sales terminal 32 of the communication terminals 30. The sales terminal communication unit 112 is connected to a taximeter 40, a payment terminal 42, an in-vehicle printer 44, and a vehicle allocation system 46, which are business terminals 32. The personal terminal communication unit 114 has a function of communicating with the personal terminal 34 of the communication terminals 30. The personal terminal communication unit 114 is connected to the smartphone 50 and the tablet terminal 52 that are the personal terminals 34. Here, the sales terminal communication unit 112 corresponds to a line for sales terminals, and the personal terminal communication unit 114 corresponds to a line for personal terminals.

  The control unit 120 has a function of controlling communication in the external communication unit 100 and the internal communication unit 110. The control unit 120 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The control unit 120 of this embodiment includes a mode acquisition unit 122 and a setting unit 124.

  The mode acquisition unit 122 functions as a detection unit that acquires the business situation of the taxi T from the taximeter 40 and detects a mode corresponding to the business situation. Here, the “modes” in the taxi T include a boarding mode in which passengers are boarding and an exit mode in which passengers are getting out. The relationship between the business situation and mode in the taximeter 40 is as shown in FIG. That is, “actual vehicle” and “payment” correspond to the boarding mode, and “empty vehicle” corresponds to the getting-off mode.

  The setting unit 124 has a function of setting one restriction level corresponding to the mode from a plurality of restriction levels for communication between the personal terminal 34 and the personal terminal communication unit 114. In the present embodiment, two levels of restriction levels are set for the communication amount of the personal terminal 34 connected to the in-vehicle communication device 10, and different threshold values are set for each restriction level. Specifically, level 0 with a traffic threshold of 1 GB and level 1 with a threshold of 0 GB (that is, communication is not possible) are set as the restriction levels.

(Function)
The restriction level setting process corresponding to the mode in the present embodiment configured as described above will be described with reference to FIG. As described above, the taximeter 40 outputs information related to the business situation of any of “empty vehicle”, “actual vehicle”, and “payment” to the in-vehicle communication device 10. On the other hand, in the in-vehicle communication device 10, the following process is executed.

  First, in step S <b> 100, the mode acquisition unit 122 acquires a business situation from the taximeter 40 through the business terminal communication unit 112. Then, the process proceeds to next Step S101.

  In step S101, the mode acquisition unit 122 detects one of the modes based on the acquired business situation. Specifically, the mode acquisition unit 122 detects that the taxi meter 40 is in the riding mode when the business status of the taximeter 40 is “actual vehicle” and “payment”, and the getting-off mode when the business status of the taximeter 40 is “empty”. (See FIG. 4). Then, the process proceeds to next Step S102.

  In step S102, the setting unit 124 determines whether or not the mode type is a boarding mode. If the setting unit 124 determines that the mode is the boarding mode, the process proceeds to step S104. On the other hand, if the setting unit 124 determines that the mode is not the boarding mode, that is, the getting-off mode, the process proceeds to the next step S103.

  In step S103, the setting unit 124 executes communication restriction. Supplementally, the setting unit 124 stops the function of the personal terminal communication unit 114 and blocks communication between the personal terminal communication unit 114 and the personal terminal 34. As a result, the level 1 restriction that disables communication is executed. Then, the process returns to step S100.

  On the other hand, when it determines with it being in boarding mode in step S102, the setting part 124 sets a threshold value to communication amount in step S104. Supplementally, the setting unit 124 sets 1 GB as the threshold value of the traffic and opens the personal terminal communication unit 114. As a result, a level 0 restriction that permits communication under certain conditions is executed. And the passenger who got on taxi T will be able to connect to the Internet IN by inputting the password displayed in the car into the smart phone 50. Then, the process proceeds to next Step S105.

  In step S105, the control unit 120 acquires the traffic. This amount of communication is the amount of communication accumulated since the personal terminal 34 was connected to the in-vehicle communication device 10. Then, the process proceeds to next Step S106. The accumulated communication amount is cleared when the boarding mode is set to the getting-off mode.

  In step S106, the setting unit 124 determines whether the communication amount has reached a threshold value. That is, in this embodiment, it is determined whether or not 1 GB set at level 0 has been reached. If the setting unit 124 determines that the threshold value of 1 GB has been reached, the process proceeds to step S103. In other words, when the communication amount reaches a preset threshold value, further communication of the personal terminal 34 may affect the communication of the sales terminal 32 due to the communication restriction of the communication carrier being applied. Communication is interrupted. On the other hand, when the setting unit 124 determines that the threshold value of 1 GB has not been reached, the process returns to step S100. That is, communication of the personal terminal 34 continues to be permitted until the communication amount reaches the threshold value.

  The in-vehicle communication device 10 configured as described above has the following effects.

  In the present embodiment, the setting unit 124 sets a restriction level corresponding to a mode from a plurality of restriction levels for communication between the communication terminal 30 and the internal communication unit 110. That is, it is possible to set a restriction level for communication with the communication terminal 30 used in the taxi T according to the business situation. Thereby, while ensuring communication of the sales terminal 32, the connection environment to the internet can be provided to a passenger.

  And according to this embodiment, when a passenger gets off from the taxi T, a passenger is prevented from connecting the personal terminal 34 to the vehicle-mounted communication device 10 and using the Internet IN by raising the regulation level. be able to. Thereby, reaching | attainment to the regulation value (for example, 7 GB) of the communication amount imposed on communication with the external communication network 20 by a communication carrier can be suppressed. In other words, taxi service will not be hindered.

  In this embodiment, the restriction level is set to be the personal terminal 34 so that the communication with the business terminal 32 is not restricted. Thereby, communication of the sales terminal 32 can be stabilized. As an additional effect, it is possible to set a restriction level and security for each business terminal 32 and individual terminal 34.

  In this embodiment, the boarding mode is applied when the business situation is “payment”. This is because the passenger may use the Internet IN, such as referring to a map even when paying. However, the present invention is not limited to this, and the getting-off mode may be applied when the business situation is “payment”.

  In the present embodiment, the communication between the personal terminal communication unit 114 and the personal terminal 34 is blocked at level 1, but this is not limited as long as the regulations are strengthened compared to level 0. For example, a threshold of 500 MB may be set at level 1 with respect to a threshold of 1 GB at level 0.

  Further, in the present embodiment, at level 0, communication is interrupted when the amount of communication accumulated after the personal terminal 34 is connected to the in-vehicle communication device 10 reaches a threshold value, but this is not restrictive. For example, communication may be blocked when the amount of communication accumulated during the charge calculation period in the in-vehicle communication device 10 reaches a threshold value. Here, the “charge calculation period” is a period during which a communication charge is calculated, and is a period for which communication restriction is determined by a communication carrier. In this case, the accumulated communication amount is cleared when the charge calculation period has elapsed.

  Further, the difference between the communication amount of the in-vehicle communication device 10 accumulated during the charge calculation period and the restriction value (for example, 7 GB) of the communication amount imposed on the communication with the external communication network 20 by the communication carrier is a predetermined value. Even when the value is smaller than the value of, the communication of the personal terminal 34 may be restricted. That is, the communication of the personal terminal 34 can be restricted when it is determined that the communication of the sales terminal 32 may be affected.

  Furthermore, both the communication amount accumulated after the personal terminal 34 is connected to the in-vehicle communication device 10 and the communication amount accumulated during the charge calculation period in the in-vehicle communication device 10 may be determined. The threshold in this case can be set for each accumulated communication amount. For example, a threshold value of 1 GB can be set for the communication amount of the personal terminal 34 and a threshold value of 5 GB can be set for the communication amount during the charge calculation period. And communication of the personal terminal 34 can be restrict | limited when the amount of any communication reaches a threshold value.

(Second Embodiment)
In the first embodiment, the communication amount of the personal terminal 34 is the target of the regulation level, but in the second embodiment, the communication speed is the target of the regulation level. Hereinafter, differences from the first embodiment will be described.

  In the setting unit 124 of the present embodiment, two levels of restriction levels are set for the communication speed, and different upper limit values are set for each restriction level. Specifically, level 0 where the upper limit value of the communication speed is 5 Mbps and level 1 where the upper limit value is 0 Mbps (that is, communication is impossible) are set as the restriction levels.

  Processing for setting the restriction level corresponding to the mode in the present embodiment will be described with reference to FIG. In the in-vehicle communication device 10, the following processing is executed.

  The processing from step S110 to step S112 is the same as the processing from step S100 to step S102 in FIG. In step S112, when the setting unit 124 determines that the mode is the riding mode, the process proceeds to step S114. On the other hand, if the setting unit 124 determines that the mode is not the boarding mode, that is, the getting-off mode, the process proceeds to the next step S113.

  In step S113, the setting unit 124 executes communication restriction. Supplementally, the setting unit 124 stops the function of the personal terminal communication unit 114 and blocks communication between the personal terminal communication unit 114 and the personal terminal 34. As a result, the level 1 restriction that disables communication is executed. Then, the process returns to step S100.

  On the other hand, when it determines with it being in boarding mode in step S112, the setting part 124 sets an upper limit to communication speed in step S114. Supplementally, the setting unit 124 sets 5 Mbps as the upper limit value of the communication speed and opens the personal terminal communication unit 114. As a result, the level 0 regulation that permits communication is executed. And the passenger who got on the taxi T will be able to connect to the Internet IN although the communication speed is limited by inputting the password displayed in the car to the smartphone 50. Then, the process returns to the next step S110.

  According to the present embodiment, the same effects as those of the first embodiment can be obtained. In this embodiment, only the communication speed is limited. However, the present invention is not limited to this, and both the communication speed and the communication amount may be limited.

(Third embodiment)
In the third embodiment, the present invention is applied to a route bus B which is a business vehicle. In other words, the present embodiment provides an environment in which the Internet IN can be connected to the inside of the route bus B which is a moving body. Hereinafter, differences from the first embodiment will be described.

  FIG. 7 is a functional block diagram of the in-vehicle communication device 10A that is the communication device of the present embodiment. In addition, the same code | symbol is attached | subjected to the same structure as 1st Embodiment, and description is omitted.

  As shown in FIG. 7, an operation management device 60 that is a business terminal 32 on a route bus B and a GPS device 62 that is a position detection device are connected to the business terminal communication unit 112 of the present embodiment.

  On the other hand, in addition to the setting unit 124, the control unit 120 of the present embodiment includes a timer unit 121, a timetable acquisition unit 126, and a position information acquisition unit 128.

  The timer unit 121 is an RTC (Real Time Clock) connected to the CPU and has a function of generating time.

The timetable acquisition unit 126 functions as a detection unit that acquires timetable information from the operation management device 60 and detects the mode of business conditions of the route bus B. Here, the “mode” in the route bus B includes a business mode that is within the business hours specified in the timetable and a non-business mode that is not business hours.
The position information acquisition unit 128 has a function of acquiring position information from the GPS device 62.

  The setting unit 124 according to the present embodiment sets the threshold value of the traffic amount to 1 GB when the mode is the sales mode, and sets the threshold value to 0 GB (that is, communication is not possible) when the mode is the non-business mode. Set to 1.

  Here, the processing in the in-vehicle communication device 10A is as shown in the flowchart of FIG. First, in step S <b> 200, the timetable acquisition unit 126 acquires timetable information from the operation management device 60 through the business terminal communication unit 112. Then, the process proceeds to the next step S201.

  In step S201, the timetable acquisition unit 126 detects one of the modes based on the acquired timetable information. Specifically, the timetable acquisition unit 126 acquires the current time from the timekeeping unit 121, detects that the current time is within business hours, detects that it is in business mode, and if the current time is outside business hours, Detect that it is in sales mode. Then, the process proceeds to next Step S202.

  In step S202, the setting unit 124 determines whether or not the mode type is the sales mode. If the setting unit 124 determines that the mode is the business mode, the process proceeds to step S204. On the other hand, if the setting unit 124 determines that the mode is not the sales mode, that is, the non-business mode, the process proceeds to the next step S203.

  In step S203, the setting unit 124 executes communication restriction as a level 1 restriction. Details are the same as step S103 in FIG. Then, the process returns to step S200.

  On the other hand, when it is determined in step S202 that the sales mode is set, in step S204, the setting unit 124 sets a threshold value for the traffic. Details are the same as step S104 in FIG. As a result, a level 0 restriction that permits communication under certain conditions is executed. Then, the process proceeds to next Step S205.

  Hereinafter, Step S205 and Step S206 are the same as Step S105 and Step S106 of FIG. 5, respectively. If the setting unit 124 determines in step S206 that the threshold value of 1 GB has not been reached, the process returns to step S200. That is, communication of the personal terminal 34 continues to be permitted until the communication amount reaches the threshold value.

  The in-vehicle communication device 10 </ b> A of the present embodiment can determine the business situation mode based on the timetable information and set the restriction level based on the mode. According to the present embodiment, the same effect as that of the first embodiment can be obtained by raising the regulation level outside business hours. Note that in this embodiment as well, as in the second embodiment, the communication speed may be subject to communication restriction instead of the communication amount.

(Fourth embodiment)
In the third embodiment, the mode of the business situation is determined based on the timetable information. In the fourth embodiment, the mode is determined based on the position information of the route bus B that is a business vehicle. Hereinafter, differences from the third embodiment will be described.

  In the present embodiment, the position information acquisition unit 128 functions as a detection unit that detects the mode of business status of the route bus B. Specifically, the position information acquisition unit 128 detects any mode based on the position information acquired from the GPS device 62. Specifically, the position information acquisition unit 128 acquires map information from a storage device (not shown), determines that the current position information is within the sales route, and determines that the current position information is outside the sales route. If it is, it is determined that it is a non-business mode.

  The processing in the in-vehicle communication device 10A of this embodiment is substantially equal to the flowchart of FIG. Supplementally, in step S200, the position information acquisition unit 128 acquires position information from the GPS device 62, and in step S201, the position information acquisition unit 128 detects any mode based on the acquired position information. Is the same as the process of FIG.

  The in-vehicle communication device 10 </ b> A of the present embodiment can determine the business situation mode based on the position information and set the restriction level based on the mode. According to the present embodiment, the same effect as that of the third embodiment can be obtained by raising the restriction level when the route bus B exists outside the business route. Note that in this embodiment as well, as in the second embodiment, the communication speed may be subject to communication restriction instead of the communication amount.

(Remarks)
In each of the above-described embodiments, the restriction levels are two levels of level 0 and level 1. However, the present invention is not limited to this, and three or more restriction levels may be set. For example, in the first embodiment, it is possible to set a plurality of restriction levels having different communication traffic thresholds. Thereby, for example, as the communication amount accumulated in the charge calculation period approaches the restriction value set by the communication carrier, the restriction level can be increased stepwise, that is, the communication amount threshold can be lowered stepwise.

  Further, for example, a plurality of restriction levels having different communication traffic thresholds can be set according to the type of passenger.
