Description

Technical Field

[0001] The present invention relates to a mobile terminal device.

Background Art

[0002] In current auctions, auction participants operate an auction terminal installed at each seat in the auction venue to participate in the auction. Therefore, when taking a break in a smoking area or a cafeteria, or when leaving the seat for on-site vehicle inspection, it is not possible to participate in the auction. Thus, there is a need to make the auction terminal a portable terminal such as a tablet so that one can participate in the auction from any location within the auction venue.

[0003] For example, an auction terminal device is disclosed that, when receiving auction information including the auction price from an auction server, transmits the auction information to a personal computer, when receiving a switch state inquiry from the auction server, transmits the state of the switch to the auction server, and when receiving a lamp lighting command from the auction server, lights or extinguishes the lamp accordingly (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] At the auction venue, there is an adjustment room (price adjustment room) for price adjustment as a specific location within the venue. In the adjustment room, the venue staff (adjuster) and the seller have conversations regarding price adjustment while adjusting the auction price. Therefore, when the auction terminal is a mobile terminal such as a tablet, it is designed to be usable anywhere within the auction venue. As a result, it becomes possible to bring the auction terminal into a specific location within the venue such as the adjustment room, which may lead to the loss of sales opportunities by obtaining information that the buyer could not originally obtain, and the fairness of the auction may be impaired.

[0006] Therefore, methods such as restricting the use of the auction terminal when approaching a specific location such as the adjustment room using GPS or making it impossible to communicate inside and outside the adjustment room (creating a radio wave anechoic chamber) can be considered.

[0007] However, in order to use the position identification function using GPS, it is necessary to continuously pay communication-related costs, resulting in communication costs. When using the GPS function, it is necessary to always enable the GPS function on the auction terminal, which accelerates the battery consumption of the auction terminal. Also, in order to make it impossible to communicate inside and outside the adjustment room, expansion is required, resulting in production (construction) costs of the equipment. In addition, since the sellers of the next lot are waiting near the adjustment room, there is a problem that personal mobile phones used by the sellers cannot be used either.

[0008] In view of the above problems, an object of the present invention is to provide a mobile terminal device that can protect the fairness of the auction while reducing production costs.

Means for Solving the Problems

[0009] In order to achieve the above object, a mobile terminal device according to the present invention is a mobile terminal device provided with a dedicated application that operates only when connected to mobile communication. In the mobile terminal device, the connection by the mobile communication is controlled according to the connection state of a wireless LAN to a dedicated access point installed at a specific location in the venue. When the wireless LAN is connected to the dedicated access point, the connection by the mobile communication is invalidated. When the wireless LAN is not connected to the dedicated access point, the connection by the mobile communication is enabled.

[0010] Further, in the mobile terminal device according to the present invention, the number of times the wireless LAN is connected to the dedicated access point is confirmed by a counter. When the counter becomes equal to or greater than a reference value, the connection by the mobile communication may be invalidated.

[0011] Further, in the mobile terminal device according to the present invention, an invalidation batch file that invalidates the connection by the mobile communication according to the connection state of the wireless LAN may be executed when the recording of an event log recorded when a connection to the wireless LAN to the dedicated access point is attempted is started.

[0012] Further, in the mobile terminal device according to the present invention, an activation batch file that activates the connection by the mobile communication according to the connection state of the wireless LAN may be executed when the recording of the event log recorded when the radio wave of the wireless LAN to the dedicated access point is cut off is started.

[0013] Further, in the mobile terminal device according to the present invention, when the connection by the mobile communication is invalidated, it may notify that the mobile communication is invalidated.

[0014] Further, the notification unit of the mobile terminal device according to the present invention may display a message indicating that the mobile communication has been invalidated.

[0015] Also, the wireless LAN of the mobile terminal device of the present invention may be Wi-Fi (registered trademark).

[0016] Also, the specific location within the venue of the mobile terminal device of the present invention may be the adjustment room of the auction venue.

Advantages of the Invention

[0017] According to the present invention, it is possible to protect the fairness of the auction while reducing the manufacturing cost.

Embodiments for Carrying Out the Invention

[0019] Hereinafter, the present embodiment will be described with reference to the drawings. Note that a plurality of embodiments can be combined and implemented within a non - contradictory range.

[0020] The auction terminal 10 according to this embodiment will be described. FIG. 1 is a diagram showing an example of the usage state and hardware configuration of the auction terminal 10 according to this embodiment. The auction terminal 10 is an example of a mobile terminal device. The auction terminal 10 is provided with an auction application that operates only when connected to a 5G base station 500 installed in the auction venue 100 by mobile communication (such as 5G communication (fifth-generation mobile communication system)). The auction terminal 10 is used to participate in the auction by the auction application in the auction venue 100. The mobile communication is not limited to 5G communication and may be 4G communication (fourth-generation mobile communication system). In this case, a 4G base station is installed instead of the 5G base station 500.

[0021] In this embodiment, the auction venue 100 is an auction venue for vehicles. The items handled at the auction venue 100 are not limited to vehicles and may be precious metals, artworks, seafood, agricultural products, livestock products, real estate, industrial products, etc.

[0022] An adjustment room 200 is installed in the auction venue 100. The adjustment room 200 is a room where the adjuster, who is a venue staff member of the auction venue 100, and the seller conduct conversations such as price adjustments and adjust the auction price. The adjustment room 200 is also called a price adjustment room. The adjustment room 200 is an example of a specific location within the venue. The specific location within the venue is not limited to the adjustment room 200 and may be a reception desk, a guide desk, a waiting room, an exhibition space, an auction management room, a data processing room, a luggage storage, a rest room, a medical room, a cafeteria.

[0023] In the adjustment room 200, a dedicated access point 300 for a wireless LAN (Local Area Network) is installed. In the present embodiment, Wi-Fi (registered trademark) is used as an example of the wireless LAN. Therefore, the dedicated access point 300 is, for example, a Wi-Fi access point. The dedicated access point 300 is not connected to a dedicated line or the Internet, and even when the serration terminal 10 is connected to the dedicated access point 300, it cannot communicate with the outside. The radio wave intensity of the dedicated access point 300 may be set arbitrarily. Note that the wireless LAN is not limited to Wi-Fi, and may be Bluetooth (registered trademark), Zigbee (registered trademark), or NFC (Near Field Communication).

[0024] An arbitrarily set SSID (Service Set Identifier) is set in the dedicated access point 300. In the present embodiment, the serration terminal 10 is set to automatically connect only to the SSID set in the dedicated access point 300 installed in the adjustment room 200. The serration terminal 10 is set not to detect any SSIDs other than the SSID set in the dedicated access point 300 installed in the adjustment room 200. Also, the Wi-Fi setting of the serration terminal 10 is restricted so that it cannot be changed. This can prevent the serration terminal 10 from being connected to an unauthorized line other than the dedicated access point 300 installed in the adjustment room 200, and prevent malfunction of the present invention (incorrect invalidation or activation of the mobile communication of the serration terminal). Also, it can prevent connection to an unauthorized line, improve the security of the serration terminal 10, and protect the fairness of the serration.

[0025] The serration terminal 10 is a portable terminal device that can be carried by a serration participant 400 within the serration venue 100. The serration terminal 10 is constituted by, for example, a tablet terminal. The serration terminal 10 may be constituted by a smartphone, a dedicated terminal, a notebook PC, or the like.

[0026] FIG. 1 shows an example of the hardware configuration of the serration terminal 10 according to the present embodiment.

[0027] The serration terminal 10 includes a terminal control unit 11, a storage unit 12, a display unit 13, an input unit 14, and a communication interface 15. The serration terminal 10 may include other hardware configurations not shown in FIG. 1.

[0028] The terminal control unit 11 comprehensively controls the entire serration terminal 10 and has a CPU (Central Processing Unit) (not shown) that reads a program and executes control processing.

[0029] The terminal control unit 11 controls the operation of the entire serration terminal 10 by expanding the programs stored in the RAM (Random Access Memory), ROM (Read Only Memory), HDD (Hard Disk Drive), SSD (Solid State Drive), etc. of the storage unit 12 into the RAM of the storage unit 12 and sequentially executing them. The terminal control unit 11 controls the overall operation of the serration terminal 10 by executing various programs such as an OS (Operating System) program and an application program.

[0030] The storage unit 12 is a RAM, ROM, HDD, SSD, etc., and stores programs executed by the terminal control unit 11, various setting information, etc. Further, the storage unit 12 can store information input in the serration terminal 10, information on the SSID of the dedicated access point 300, the value of the counter, the reference value of the value of the counter, etc.

[0031] The serration terminal 10 records the event ID of the event log in the storage unit 12 when connecting to the dedicated access point 300 via Wi-Fi. The event ID of the event log recorded at the time of Wi-Fi connection is identification information indicating that Wi-Fi has been connected. The serration terminal 10 can grasp that Wi-Fi has been connected to the dedicated access point 300 based on the fact that the event ID of the event log recorded at the time of Wi-Fi connection has been recorded.

[0032] In addition, when the Wi-Fi connection between the auction terminal 10 and the dedicated access point 300 is disconnected, the event ID of the event log is recorded in the storage unit 12. The event ID of the event log recorded at the time of Wi-Fi disconnection is identification information indicating that the Wi-Fi has been disconnected. Based on the fact that the event ID of the event log recorded at the time of Wi-Fi disconnection is recorded, the auction terminal 10 can grasp that the Wi-Fi connection to the dedicated access point 300 has been disconnected.

[0033] The display unit 13 is a display such as a liquid crystal display (LCD) or an organic electro-luminescence (OLED), and displays an operation screen or the like for the auction participant 400 who operates the auction terminal 10 under the control of the terminal control unit 11. The display unit 13 is an example of the notification unit. Therefore, when the connection by 5G communication is disabled, the display unit 13 notifies that the 5G communication is disabled. In addition, the display unit 13 displays a message indicating that the 5G communication has been disabled.

[0034] The input unit 14 is a touch panel integrated with the display unit 13 or a mouse or keyboard connected to the interface of the auction terminal 10, and receives input instructions from the auction participant 400. The input information is notified to the terminal control unit 11. The input unit 14 receives inputs such as bids and amounts in the auction based on the input instructions from the auction participant 400.

[0035] The communication interface 15 performs wireless communication with the 5G base station 500 through 5G communication under the control of the terminal control unit 11. In addition, the communication interface 15 performs wireless communication with the dedicated access point 300 through Wi-Fi communication under the control of the terminal control unit 11. The communication interface 15 is, for example, a network adapter.

[0036] The sushi terminal 10 is preset with a task scheduler that executes a batch file for disabling 5G communication (disabling batch file) and a task scheduler that executes a batch file for enabling 5G communication (enabling batch file). The task scheduler that executes the batch file for disabling 5G communication has the event ID of the event log recorded when connecting to the dedicated access point 300 via Wi-Fi set as a trigger, and the execution of the batch file for disabling 5G communication is set as an operation. The task scheduler that executes the batch file for enabling 5G communication has the event ID of the event log recorded when disconnecting from the dedicated access point 300 via Wi-Fi set as a trigger, and the execution of the batch file for enabling 5G communication is set as an operation.

[0037] Next, a flowchart showing an example of the disabling process executed by the sushi terminal 10 will be described. FIG. 2 is a flowchart showing an example of the disabling process executed by the sushi terminal 10 as a computer.

[0038] When the sushi participant 400 carrying the sushi terminal 10 is at a distance of a certain distance or more from the adjustment room 200, the 5G communication is not disabled by the disabling process. Therefore, the 5G communication with the 5G base station 500 is effective, and the sushi application provided in the sushi terminal 10 is operating (step S101). The certain distance is a distance at which the conversation between the adjuster and the seller cannot be heard.

[0039] When the sushi participant 400 approaches the adjustment room 200 while carrying the sushi terminal 10, the sushi terminal 10 determines whether it has received the Wi-Fi radio waves transmitted from the dedicated access point 300 based on the SSID of the dedicated access point 300 installed in the adjustment room 200 (step S102). If it has not received the Wi-Fi radio waves transmitted from the dedicated access point 300 (step S102: NO), it waits in the process of step S102 until it receives the Wi-Fi radio waves transmitted from the dedicated access point 300. If it has received the Wi-Fi radio waves transmitted from the dedicated access point 300 (step S102: YES), the sushi terminal 10 attempts to connect to the dedicated access point 300 installed in the adjustment room 200 via Wi-Fi (step S103). The sushi terminal 10 determines whether the event ID of the event log at the time of Wi-Fi connection has been recorded as a result of attempting the Wi-Fi connection (step S104).

[0040] If the event ID of the event log at the time of Wi-Fi connection has not been recorded (step S104: NO), it waits in the process of step S104 until the event ID of the event log at the time of Wi-Fi connection is recorded in the storage unit 12. When the Wi-Fi connection is made and the event ID of the event log is recorded in the storage unit 12 (step S104: YES), the sushi terminal 10 executes a batch file for disabling 5G communication by a task scheduler triggered by the recording of the event ID of the event log (step S105).

[0041] The sushi terminal 10 checks the Wi-Fi status (step S106). The sushi terminal 10 checks the Wi-Fi connection status with respect to the dedicated access point 300 installed in the adjustment room 200 (step S107). The Wi-Fi connection status checked in step S107 refers to the state where the sushi terminal 10 is connected to the Wi-Fi of the dedicated access point 300. In step S107, even if the Wi-Fi connection was attempted in the process of step S103, there may be a case where it is not connected to the Wi-Fi, so the connection check process is executed.

[0042] When Wi-Fi is not in a connected state (step S107: NO), it is checked whether Wi-Fi is in a disconnected state (step S108). The Wi-Fi disconnection state checked in step S108 refers to a state in which the seiri terminal 10 is disconnected from the Wi-Fi of the dedicated access point 300. In step S108, even if the connection by Wi-Fi was attempted in the process of step S103, the state of Wi-Fi may not be determined, so the disconnection confirmation process is executed.

[0043] When Wi-Fi is in a disconnected state (step S108: YES), the seiri terminal 10 determines that it has only detected the Wi-Fi of the dedicated access point 300, that is, it has only passed near the adjustment room 200, and returns to the process of step S102 without changing the 5G communication settings.

[0044] When Wi-Fi is not in a disconnected state (step S108: NO), the seiri terminal 10 determines that the state of Wi-Fi is not determined, initializes the value of the counter to "0", waits for the first time (step S110), and returns to the process of step S106. The first time can be set arbitrarily. For example, 5 seconds can be set as the first time.

[0045] When Wi-Fi is in a connected state (step S107: YES), the seiri terminal 10 increments the value of the counter by "1" (step S111). As a result of incrementing the value of the counter by "1", the seiri terminal 10 checks the value of the counter (step S112).

[0046] As a result of checking the value of the counter, the seiri terminal 10 determines whether the value of the counter is equal to or greater than the reference value (step S113). The value of the reference value can be set arbitrarily. For example, "3" can be set as the reference value.

[0047] When the value of the counter is less than the reference value (step S113: NO), the auction terminal 10 waits for a second time (step S114), and the process returns to step S106. The second time can be arbitrarily set. For example, 10 seconds can be set as the second time.

[0048] When the value of the counter is greater than or equal to the reference value (step S113: YES), for example, when the value of the counter becomes "3" or more, the auction terminal 10 invalidates the 5G communication with the 5G base station 500 on the communication interface 15 (step S115).

[0049] When the 5G communication is invalidated, the operation of the auction application is stopped (step S116).

[0050] When the 5G communication of the auction terminal 10 is invalidated, the auction terminal 10 displays a 5G communication invalidation message on the display of the display unit 13 (step S117). The 5G communication invalidation message is a text that notifies the auction participant 400 that the 5G communication is invalid and the auction application cannot be used.

[0051] Figure 3 is an example of the 5G communication invalidation message 600 displayed on the display of the display unit 13. In the embodiment of Figure 3, as the 5G communication invalidation message 600, it is displayed that the use of the auction terminal 10 is restricted and that it is necessary to move away from the adjustment room 200 to use the auction terminal 10. As shown in Figure 3, the auction terminal 10 displays the 5G communication invalidation message 600 on the entire screen of the display of the display unit 13. The auction participant 400 who has seen the 5G communication invalidation message 600 can grasp that the 5G communication is currently invalid and the operation of the auction application has stopped.

[0052] In the embodiment of FIG. 3, the 5G communication disabling message 600 is displayed full screen on the display, but this is not the only case, and it may be displayed in an arbitrary area of a part of the display of the display unit 13. Further, instead of the 5G communication disabling message 600, the sushi terminal 10 may display an icon indicating that 5G communication is disabled or a color indicating that it is disabled. Further, a speaker or a buzzer that functions as a notification unit may be provided, and a notification sound notifying that 5G communication is disabled may be emitted from the speaker or the buzzer. When the process of step S117 ends, the disabling process ends.

[0053] Next, a flowchart showing an example of the enabling process executed by the sushi terminal 10 will be described. FIG. 4 is a flowchart showing an example of the enabling process executed by the sushi terminal 10 as a computer. The enabling process is a process executed after 5G communication is disabled in the disabling process.

[0054] When the sushi participant 400 carrying the sushi terminal 10 is within a distance less than a certain distance from the adjustment room 200, 5G communication is disabled by the disabling process. For this reason, 5G communication with the 5G base station 500 is disabled, and the operation of the sushi application provided in the sushi terminal 10 has stopped (step S201). While the operation of the sushi application is stopped, the 5G communication disabling message 600 shown in FIG. 3 continues to be displayed on the display of the display unit 13.

[0055] When the sushi participant 400 leaves the adjustment room 200 while carrying the sushi terminal 10, the sushi terminal 10 determines whether or not it has been disconnected from the Wi-Fi radio wave transmitted from the dedicated access point 300 installed in the adjustment room 200 (step S202). If the Wi-Fi radio wave transmitted from the dedicated access point 300 has not been disconnected (step S202: NO), the process waits in step S202 until it is disconnected from the Wi-Fi radio wave transmitted from the dedicated access point 300.

[0056] When disconnected from the Wi-Fi radio waves transmitted from the dedicated access point 300 (step S202: YES), it is determined whether the event ID of the event log at the time of Wi-Fi disconnection is recorded (step S203).

[0057] When the event ID of the event log at the time of Wi-Fi disconnection is not recorded in the storage unit 12 (step S203: NO), the process waits in the process of step S203 until the event ID of the event log at the time of Wi-Fi disconnection is recorded in the storage unit 12. Then, when the event ID of the event log at the time of Wi-Fi disconnection is recorded in the storage unit 12 (step S203: YES), the server terminal 10 executes a batch file for enabling 5G communication by a task scheduler triggered by the recording of the event ID of the event log (step S204).

[0058] The server terminal 10 checks the Wi-Fi status (step S205). The server terminal 10 checks the Wi-Fi connection status with respect to the dedicated access point 300 installed in the adjustment room 200 (step S206). The Wi-Fi connection status checked in step S206 refers to the state in which the server terminal 10 is connected to the Wi-Fi of the dedicated access point 300. In step S206, even if it was disconnected from the Wi-Fi radio waves in the process of step S202, it may have been temporarily disconnected from the Wi-Fi, so the disconnection confirmation process is executed.

[0059] When Wi-Fi is in the connected state (step S206: YES), the server terminal 10 determines that it has been temporarily disconnected from Wi-Fi, and the process returns to step S202.

[0060] When Wi-Fi is not in a connected state (step S206: NO), it is checked whether Wi-Fi is in a disconnected state (step S207). The Wi-Fi disconnection state checked in step S207 refers to a state in which the sushi terminal 10 is disconnected from the Wi-Fi of the dedicated access point 300. In step S207, even if it was disconnected from the Wi-Fi radio wave in the process of step S202, it may have been only temporarily disconnected, so the disconnection confirmation process is executed.

[0061] When Wi-Fi is not in a disconnected state (step S207: NO), since the connection state of Wi-Fi is not determined, the sushi terminal 10 waits for a third period of time (step S208), and the process returns to step S205. The third period of time can be arbitrarily set. For example, 5 seconds can be set as the third period of time.

[0062] When Wi-Fi is in a disconnected state (step S207: YES), the sushi terminal 10 activates 5G communication with the 5G base station 500 on the communication interface 15 (step S209).

[0063] When 5G communication is activated, the operation of the sushi application is started (step S210).

[0064] When 5G communication is activated, the sushi terminal 10 ends the display of the 5G communication deactivation message 600 displayed on the display of the display unit 13 (step S211). The sushi participant 400 who sees that the display of the 5G communication deactivation message 600 has ended can grasp that 5G communication is currently active and the operation of the sushi application has started.

[0065] As described above, when the seri participant 400 carrying the seri terminal 10 is outside the adjustment room 200 in the seri venue 100, the connection by 5G communication is enabled between the seri terminal 10 and the 5G base station 500. Therefore, the operation of the seri application on the seri terminal 10 can be started to allow participation in the seri through the seri application. On the other hand, when the seri participant 400 carrying the seri terminal 10 is in the adjustment room 200 in the seri venue 100, the connection by 5G communication is disabled between them. Thus, the operation of the seri application on the seri terminal 10 can be stopped to halt the participation in the seri. As a result, the operation of the seri application can be controlled only by providing the dedicated access point 300, so that the manufacturing cost can be reduced while protecting the fairness of the seri.

[0066] Also, in the above-described embodiment, the number of times the Wi-Fi connection to the dedicated access point 300 is established is confirmed by a counter. When the confirmed counter reaches or exceeds a reference value, the 5G communication connection is disabled. This can prevent malfunction such that the operation of the seri application stops just by passing near the adjustment room 200, and can improve the customer satisfaction of the seri participant 400.

[0067] Further, in the above-described embodiment, when the 5G communication connection is disabled, a 5G communication disable message 600 indicating that the 5G communication is disabled is displayed on the display of the display unit 13. Thereby, the seri participant 400 can be notified that the seri application is unavailable.

[0068] In the above-described embodiment, the auction terminal 10 controls the connection via 5G communication according to the Wi-Fi connection state to the dedicated access point 300 installed in the adjustment room 200 within the auction venue 100, but it is not limited to this. For example, the auction terminal 10 may control the connection via 5G communication according to the reception intensity of the Wi-Fi transmitted from the dedicated access point 300 installed in the adjustment room 200 within the auction venue 100. In this case, the auction terminal 10 has the function of a spectrum analyzer capable of measuring the reception intensity of the Wi-Fi.

[0069] When the reception intensity transmitted from the dedicated access point 300 is equal to or higher than the threshold value, that is, when approaching the adjustment room 200, the connection via 5G communication is invalidated. When the reception intensity transmitted from the dedicated access point 300 is less than the threshold value, that is, when moving away from the adjustment room 200, the connection via 5G communication is enabled. The threshold value can be arbitrarily set. By simply changing the threshold value, the range in which the auction application can operate can be easily set. Thereby, by providing only the dedicated access point 300, the operation of the auction application can be controlled, so that while reducing the manufacturing cost, the fairness of the auction can be protected.

[0070] Note that the present invention is not limited to the above-described embodiment as it is, and components can be modified and embodied without departing from the gist thereof at the implementation stage. Also, various inventions can be formed by appropriately combining a plurality of components disclosed in the above-described embodiment. For example, all the components shown in the embodiment may be appropriately combined. Further, components from different embodiments may be appropriately combined. Of course, various modifications and applications can be made without departing from the spirit of the invention.
