Description

[Technical field]

[0001] The present disclosure relates to an entrance / exit management system, a mobile terminal, a reading device, an entrance / exit management method, and an entrance / exit management program. [Background technology]

[0002] An entry / exit management system has been developed that includes a portable terminal that holds a user's authentication identification information, a reading device that acquires the user's authentication identification information via wireless communication, and an authentication device that performs entry / exit authentication of the user using the user's recognition identification information acquired by the reading device.

[0003] For example, the authentication system of Patent Document 1 includes a mobile terminal having a transmission means for transmitting an authentication request signal including a user's ID information to the authentication device, a storage unit for storing the user's ID information, and an authentication device having an authentication means for performing user authentication processing by comparing the ID information included in the authentication request signal with ID information previously stored in the storage unit when an authentication request signal is received from the mobile terminal. With this configuration, user authentication is performed using the mobile terminal. Here, for wireless communication between the mobile terminal and the authentication device, a wireless module having a wireless communication interface such as BLE (Bluetooth (registered trademark) Low Energy), ZigBee (registered trademark), or Wi-Fi (registered trademark) is used.

[0004] [Patent Document 1] JP 2019-175252 A Summary of the Invention [Problem to be solved by the invention]

[0005] It is expected that an entrance / exit management system will appear that performs wireless communication between a mobile terminal and a reader using UWB (Ultra Wide Band), a wireless communication method that is characterized by ultra-high speed communication, centimeter-level high-precision positioning and ranging, and little interference with other wireless communication methods. At the same time, in response to the diversification of wireless communication methods, an entrance / exit management system using a reader that can support multiple wireless communication methods has also appeared. Here, the multiple wireless communication methods are UWB, NFC (Near field communication), BLE, Wi-Fi, etc. Here, in a situation where an entrance / exit management system using a reading device capable of supporting multiple wireless communication methods is used, when an appropriate wireless communication method is to be selected from multiple wireless communication methods, the authentication system of Patent Document 1 only describes that a wireless module having a wireless communication interface such as BLE, ZigBee, or Wi-Fi is used for wireless communication between a mobile terminal and an authentication device. In other words, in a situation where an entrance / exit management system using a reading device capable of supporting multiple wireless communication methods is used, appropriate selection of a wireless communication method to be used for wireless communication between a mobile terminal and a reading device from multiple wireless communication methods is not considered. Therefore, a situation occurs in which it is difficult to appropriately select a wireless communication method taking into account the user's intention, the wireless communication method compatible with the mobile terminal, the wireless communication method compatible with the reading device, etc. As a result, there is a problem that the user cannot appropriately use the entrance / exit management system. Here, the user includes a person whose entrance / exit is managed by the entrance / exit management system and a person who manages entrance / exit by the entrance / exit management system.

[0006] The present disclosure has been made to solve the above-mentioned problems, and aims to provide an entry / exit management system that allows users to appropriately use the entry / exit management system. [Means for solving the problem]

[0007] The entry / exit management system according to the present disclosure is an entry / exit management system comprising: a portable terminal that holds authentication identification information, which is information that identifies a user; a reading device that acquires the authentication identification information from the portable terminal via a first wireless communication; and an authentication device that performs entry / exit authentication of the user using the authentication identification information acquired by the reading device, wherein the reading device comprises a reading device control unit that notifies the portable terminal of first information including a first wireless communication method, which is a plurality of wireless communication methods that the reading device can support; and the portable terminal comprises a portable terminal control unit that uses the first information acquired from the reading device control unit and second information including a second wireless communication method, which is a wireless communication method that the portable terminal can support, to determine a fourth wireless communication method to be used for the first wireless communication from a third wireless communication method, which is a wireless communication method common to the first information and the second information, and notifies the reading device of fourth information, which is information indicating the fourth wireless communication method.

[0010] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Embodiment 1

[0011] An entrance / exit management system 100A according to the present embodiment will be described with reference to FIG. The entrance and exit management system 100A includes a mobile terminal 1A, a plurality of reading devices 2A-1 to 2A-n, a plurality of electronic locks 3A-1 to 3A-n, and authentication devices 4A-1 to 4A-n. The entrance / exit management system 100A is installed in a building, a facility, etc. In the entrance / exit management system 100A, a portable terminal 1A that holds recognition identification information, which is information for identifying a user of a building, facility, etc., communicates wirelessly with a reader 2A, whereby the reader 2A acquires authentication identification information from the portable terminal 1A, and an authentication device 4A performs entrance / exit authentication of the user using the authentication identification information acquired by the reader 2A.

[0012] In the following description, the multiple reading devices 2A-1 to 2A-n are configured in the same manner, and when there is no need to distinguish between the reading devices 2A-1 to 2A-n, the reference numeral following the hyphen indicating the reading device 2A-1 to 2A-n is omitted, and the reading device is referred to as the "reading device 2A." The same applies to other configurations that are described using hyphens. For convenience of explanation, the authentication device 4A shown in FIG. 1 is shown in a one-to-one relationship with the mobile terminal 1A, but may have an M-to-N relationship (M and N are both natural numbers equal to or greater than 1). The authentication device 4A may be provided for each building or facility in which a door to be locked or unlocked is provided, or may be provided for each floor of a building or the like.

[0013] The mobile terminal 1A includes an input unit 10A, an output unit 11A, a control unit 12A, a storage unit 13A, a first wireless communication unit 14A, a second wireless communication unit 15A, and a third wireless communication unit 16A. Furthermore, the control unit 12A includes a wireless communication method determination unit 17A.

[0014] The mobile terminal 1A is a smartphone or the like carried by a user.

[0015] The input unit 10A is an input device such as a key switch or a touch panel device, or a voice input device such as a microphone. The input unit 10A accepts input of authentication identification information and other information from a user. Here, the authentication identification information is, for example, an ID number or employee number assigned to each user. Alternatively, the authentication identification information may be an identification number or serial number set for each mobile terminal 1A held by the user.

[0016] The output unit 11A is a display device such as a liquid crystal display, an audio output device such as a speaker, a vibration generator such as a vibration, etc. The output unit 11A notifies the user of notification contents such as authentication identification information, a fourth wireless communication method described later, and other information. In this embodiment, an example has been shown in which the output unit 11A notifies the user of the notification contents such as the authentication identification information, the fourth wireless communication method, etc., but notification of the authentication identification information, the fourth wireless communication method, etc. to the user is not essential and may not be required.

[0017] The control unit 12A is a processor such as a CPU (Central Processing Unit) that executes a program recorded in the storage unit 13A and controls and performs calculations on the mobile terminal 1A.

[0018] The wireless communication method determination unit 17A uses the first information indicating the first wireless communication method, the second information indicating the second wireless communication method, and the priority table to determine which wireless communication method is to be used in the wireless communication between the portable terminal 1A and the reader 2A in the entrance / exit authentication. Details will be described later.

[0019] The storage unit 13A stores a program for controlling and calculating the portable terminal 1A executed by the control unit 12A. The storage unit 13A may also store authentication identification information and the like in advance. The storage unit 13A also stores in advance a priority table that defines which wireless communication method is to be used preferentially in wireless communication between the portable terminal 1A and the reading device 2A during entrance / exit authentication.

[0020] Here, the priority table will be described with reference to FIG. As shown in FIG. 2, the priority table specifies which wireless communication method is to be used preferentially in wireless communication between the portable terminal 1A and the reader 2A in entrance / exit authentication among wireless communication methods such as NFC, BLE, Wi-Fi, and UWB. For example, in FIG. 2, the priority is specified as UWB, BLE, NFC, and Wi-Fi in descending order of priority. Here, if both the portable terminal 1A and the reader 2A are compatible with UWB, BLE, and NFC, UWB, which has the highest priority among UWB, BLE, and NFC, is used for wireless communication between the portable terminal 1A and the reader 2A in entrance / exit authentication. Also, if both the portable terminal 1A and the reader 2A are compatible with BLE and NFC, BLE, which has the highest priority among BLE and NFC, is used for wireless communication between the portable terminal 1A and the reader 2A in entrance / exit authentication. The priority table is appropriately determined taking into consideration the design guidelines of the entrance and exit control system 100A, the communication distance of each wireless communication method, the mobile terminal position identification accuracy of each wireless communication method, the penetration rate of each wireless communication method, and the like.

[0021] The storage unit 13A can have a semiconductor memory such as a random access memory (RAM), a read only memory (ROM), an erasable programmable ROM (EPROM), etc. In addition, the storage unit 13A may be any type of storage device such as a magnetic storage device, an optical storage device, etc., in addition to a semiconductor memory such as a flash memory.

[0022] The first wireless communication unit 14A performs wireless communication with the reader 2A by an eleventh wireless communication method such as NFC, BLE, Wi-Fi, UWB, etc. Here, the first wireless communication unit 14A performs wireless communication by a wireless communication method different from that of the second wireless communication unit 15A and the third wireless communication unit 16A.

[0023] The second wireless communication unit 15A performs wireless communication with the reader 2A by a twelfth wireless communication method such as NFC, BLE, Wi-Fi, UWB, etc. Here, the second wireless communication unit 15A performs wireless communication by a wireless communication method different from that of the first wireless communication unit 14A and the third wireless communication unit 16A.

[0024] The third wireless communication unit 16A performs wireless communication with the reader 2A by a thirteenth wireless communication method such as NFC, BLE, Wi-Fi, UWB, etc. Here, the third wireless communication unit 16A performs wireless communication by a wireless communication method different from that of the first wireless communication unit 14A and the second wireless communication unit 15A.

[0025] The mobile terminal 1A includes the first wireless communication unit 14A, the second wireless communication unit 15A, and the third wireless communication unit 16A, and therefore supports the 11th, 12th, and 13th wireless communication schemes. In other words, the mobile terminal 1A does not support wireless communication schemes other than the 11th, 12th, and 13th wireless communication schemes.

[0026] In the following description, the wireless communication methods that the mobile terminal 1A can support are collectively referred to as the second wireless communication method. The second wireless communication method in this embodiment includes the 11th wireless communication method, the 12th wireless communication method, and the 13th wireless communication method.

[0027] In the present embodiment, an example in which the mobile terminal 1A is equipped with three wireless communication units has been shown, but the mobile terminal 1A may be equipped with one or more wireless communication units, i.e., the mobile terminal 1A may be compatible with one or more wireless communication methods.

[0028] The reading device 2A includes a control unit 20A, a storage unit 21A, an authentication device I / F unit 22A, a first wireless communication unit 23A, a second wireless communication unit 24A, and a third wireless communication unit 25A.

[0029] The reading device 2A is installed near the door through which users enter and exit the room. The reading devices 2A-1 to 2A-n and the electronic locks 3A-1 to 3A-n are provided in correspondence with each other. For example, the reading device 2A-1 corresponds to the electronic lock 3A-1, and the reading device 2A-n corresponds to the electronic lock 3A-n.

[0030] The control unit 20A is a processor such as a CPU that executes a program recorded in the storage unit 21A and controls and performs calculations on the reading device 2A.

[0031] The storage unit 21A stores a program for controlling and calculating the reader 2A, which is executed by the control unit 20A. The storage unit 21A may have a semiconductor memory such as a RAM, a ROM, an EPROM, etc. The storage unit 21A may have any type of storage device, such as a magnetic storage device, an optical storage device, etc., in addition to a semiconductor memory such as a flash memory.

[0032] The authentication device I / F unit 22A is connected to the authentication device 4A wirelessly or by wire via a local network, a wide area network, etc., and is an interface used when the reading device 2A outputs authentication identification information to the authentication device 4A.

[0033] The first wireless communication unit 23A performs wireless communication with the mobile terminal 1A by a 21st wireless communication method such as NFC, BLE, Wi-Fi, UWB, etc. Here, the first wireless communication unit 23A performs wireless communication by a wireless communication method different from that of the second wireless communication unit 24A and the third wireless communication unit 25A.

[0034] The second wireless communication unit 24A performs wireless communication with the mobile terminal 1A by a wireless communication method such as NFC, BLE, Wi-Fi, UWB, etc. Here, the second wireless communication unit 24A performs wireless communication by a wireless communication method different from that of the first wireless communication unit 23A and the third wireless communication unit 25A.

[0035] The third wireless communication unit 25A performs wireless communication with the mobile terminal 1A by a wireless communication method such as NFC, BLE, Wi-Fi, UWB, etc. Here, the third wireless communication unit 25A performs wireless communication by a wireless communication method different from the first wireless communication unit 23A and the second wireless communication unit 24A.

[0036] The reader 2A includes the first wireless communication unit 23A, the second wireless communication unit 24A, and the third wireless communication unit 25A, and therefore supports the 21st, 22nd, and 23rd wireless communication methods. In other words, the reader 2A does not support wireless communication methods other than the 21st, 22nd, and 23rd wireless communication methods.

[0037] In the following description, the wireless communication methods that the reader 2A can support are collectively referred to as the first wireless communication method. The first wireless communication method in this embodiment includes the 21st wireless communication method, the 22nd wireless communication method, and the 23rd wireless communication method.

[0038] In the present embodiment, an example in which the reader 2A is equipped with three wireless communication units has been shown, but the reader 2A may be equipped with multiple wireless communication units, i.e., the reader 2A may be compatible with multiple wireless communication methods. Furthermore, among the readers 2A-1 to 2A-n, the number of wireless communication methods that each reader 2A can support does not need to be uniform, and the number of wireless communication methods that each reader 2A can support may differ.

[0039] The electronic lock 3A is a lock system incorporating a mechanism for electrically locking and unlocking the door so that the door key can be remotely operated from an external device. The electronic lock 3A locks and unlocks the door under the control of, for example, an authentication device 4A. Note that, although an example in which the electronic lock 3A is installed on the door has been shown, in the case of an automatic door, a flapper gate, etc., the authentication device 4A issues an instruction to a control unit installed on the automatic door, flapper gate, etc. to open or close the door.

[0040] The authentication device 4A includes a control unit 40A, a storage unit 41A, reading device I / F units 42A-1 to 42A-n, and electronic lock I / F units 43A-1 to 43A-n. The control unit 40A further includes an entry / exit authentication unit 44A.

[0041] The control unit 40A is a processor such as a CPU that executes a program recorded in the storage unit 41A and controls and performs calculations on the authentication device 4A.

[0042] The entry / exit authentication unit 44A determines whether or not the user is permitted to enter or exit a building, facility, etc. by comparing the authentication identification information acquired via the reading device I / F unit 42A with an authentication identification information table described later, and controls the electronic lock 3A via the electronic lock I / F unit 43A based on the entry / exit permission result.

[0043] The storage unit 41A stores a program for controlling and calculating the authentication device 4A, which is executed by the control unit 40A. The storage unit 41A also stores in advance an authentication identification information table, which is a table showing unlockable doors for each authentication identification information. In this embodiment, the memory unit 41A has been described as having stored in advance an authentication identification information table, which is a table indicating doors that can be unlocked for each authentication identification information. However, the authentication identification information table stored in a server or the like may be obtained from the server each time entry / exit authentication is performed.

[0044] Here, the authentication identification information table will be described with reference to FIG. As shown in Fig. 3, the authentication identification information table shows the doors that can be unlocked for each piece of authentication identification information. For example, in the case of authentication identification information 1, the doors that can be unlocked are door 1, door 2, door 3, and door 4. In the case of authentication identification information 2, the doors that can be unlocked are door 1, door 2, and door 3. In the case of authentication identification information 3, the doors that can be unlocked are door 1 and door 2. In this embodiment, only doors are described as unlockable doors in the authentication identification information table, but the invention is not limited to doors and may include flapper gates, automatic doors, and the like.

[0045] The storage unit 41A can have a semiconductor memory such as a RAM, a ROM, an EPROM, etc. Furthermore, the storage unit 41A may have any type of storage device such as a magnetic storage device, an optical storage device, etc., in addition to a semiconductor memory such as a flash memory.

[0046] The reading device I / F unit 42A is connected to the reading device 2A wirelessly or by wire via a local network, a wide area network, etc., and is an interface used when the authentication device 4A obtains authentication identification information from the reading device 2A. The reading device I / F units 42A-1 to 42A-n correspond to the authentication device I / F units 22A-1 to 22A-n, respectively.

[0047] The electronic lock I / F unit 43A is connected to the electronic lock 3A wirelessly or by wire via a local network, a wide area network, etc., and is an interface used when the authentication device 4A controls the electronic lock 3A. The electronic lock I / F units 43A-1 to 43A-n correspond to the electronic locks 3A-1 to 3A-n, respectively.

[0048] An example of the operation of the entrance and exit management system 100A will be described with reference to FIGS.

[0049] FIG. 4 shows a sequence diagram illustrating the process performed between the mobile terminal 1A and the reader 2A. The sequence diagram shown in FIG. 4 shows a process for determining which wireless communication method is to be used in wireless communication between the portable terminal 1A and the reader 2A during entrance and exit authentication in the entrance and exit management system 100A.

[0050] First, the control unit 20A notifies the mobile terminal 1A of first information, which is information indicating a first wireless communication method, by a predetermined wireless communication method (step ST101). Here, the first information may be notified periodically, or may be notified when requested by the mobile terminal 1A.

[0051] Then, the wireless communication system determination unit 17A uses the first information and the second information, which is information indicating the second wireless communication system, to determine a common wireless communication system common to the first information and the second information as a third wireless communication system. Furthermore, the wireless communication system determination unit 17A determines the wireless communication system with the highest priority from the third wireless communication systems as a fourth wireless communication system by using the priority table shown in FIG. 2 (step ST102).

[0052] Then, the control unit 12A notifies the reading device 2A of the fourth information, which is information indicating the fourth wireless communication method, via a predetermined wireless communication method (step ST103).

[0053] Then, the control unit 12A notifies the user of the fourth information via the output unit 11A (step ST104).

[0054] Then, the portable terminal 1A and the reader 2A perform wireless communication using the fourth wireless communication method (steps ST105 and ST106).

[0055] Here, a specific example will be given for the sequence diagram shown in FIG. In this embodiment, the 11th and 21st wireless communication methods are UWB, the 12th and 22nd wireless communication methods are BLE, and the 13th and 23rd wireless communication methods are NFC. That is, the second wireless communication method that is a wireless communication method that the portable terminal 1A can support is UWB, BLE, and NFC, and the first wireless communication method that is a wireless communication method that the reader 2A can support is also UWB, BLE, and NFC. In this case, through steps ST101 to ST106 shown in FIG. 4, the third wireless communication scheme becomes UWB, BLE, and NFC, and the fourth wireless communication scheme becomes UWB.

[0056] Furthermore, a different concrete example will be given. In this embodiment, the eleventh wireless communication method is BLE, the twelfth wireless communication method is NFC, and the thirteenth wireless communication method is Wi-Fi. The twenty-first wireless communication method is UWB, the twenty-second wireless communication method is BLE, and the twenty-third wireless communication method is NFC. That is, the second wireless communication method that is compatible with the portable terminal 1A is BLE, NFC, and Wi-Fi, and the first wireless communication method that is compatible with the reader 2A is UWB, BLE, and NFC. In this case, through steps ST101 to ST106 shown in FIG. 4, the third wireless communication scheme becomes BLE and NFC, and the fourth wireless communication scheme becomes BLE.

[0057] Next, FIG. 5 shows a flowchart illustrating the process performed by the mobile terminal 1A in step ST102 of FIG.

[0058] First, the wireless communication method determination unit 17A uses the first information and the second information to determine a third wireless communication method common to the first information and the second information (step ST201).

[0059] Then, the wireless communication system determination unit 17A judges whether the third wireless communication system is a single system or a plurality of systems (step ST202).

[0060] Then, if there is a single third wireless communication method (YES in step ST202), wireless communication method determination section 17A sets the third wireless communication method as the fourth wireless communication method (step ST203).

[0061] Then, if there are multiple third wireless communication methods (if step ST202 is NO), the wireless communication method decision unit 17A uses the priority table shown in FIG. 2 to determine the wireless communication method with the highest priority as the fourth wireless communication method (step ST204).

[0062] Then, the output unit 11A notifies the user of the fourth information (step ST205).

[0063] Next, FIG. 6 shows a sequence diagram of the entrance / exit authentication process. First, the control unit 12A outputs the read authentication identification information to the reader 2A via a wireless communication unit used for the fourth wireless communication method (step ST301).

[0064] Then, the control unit 20A outputs the acquired authentication identification information to the authentication device 4A (step ST302).

[0065] Then, the entry / exit authentication unit 44A compares the authentication identification information acquired from the reader 2A with the authentication identification information table to determine whether or not the user is permitted to enter or leave the building, facility, or the like (step ST303).

[0066] Then, the entry / exit authentication unit 44A controls the electronic lock 3A based on the result of the entry / exit permission (step ST304).

[0067] FIG. 7 shows a flowchart illustrating the processes in steps ST303 and ST304 in FIG.

[0068] First, the entry / exit authentication unit 44A identifies an unlockable door set in the authentication identification information acquired from the reader 2A in the authentication identification information table shown in FIG. 3 (step ST401).

[0069] Then, the entry / exit authentication unit 44A judges whether or not the door where the reader 2A that outputted the authentication identification information is installed is included in the identified unlockable doors (step ST402). Here, the information identifying which of the reading device 2A-1 to reading device 2A-n the reading device that output the authentication identification information is is determined by which of the reading device I / F units 42A-1 to 42A-n the entry / exit authentication unit 44A used to obtain the authentication identification information from the reading device 2A. For example, when the entrance / exit authentication unit 44A acquires the authentication identification information via the reader I / F unit 42A-1, the reader 2A that has output the authentication identification information is determined to be the reader 2A-1.

[0070] Then, if the identified unlockable doors include the door in which the reading device 2A that output the authentication identification information is installed (if step ST402 is YES), the entry / exit authentication unit 44A unlocks the electronic lock 3A corresponding to the reading device 2A (step ST403).

[0071] If the identified unlockable doors do not include the door in which the reading device 2A that output the authentication identification information is installed (NO in step ST402), the electronic lock 3A is not unlocked (step ST404).

[0072] The entry / exit management system 100A of this embodiment includes a portable terminal 1A that holds authentication identification information, which is information that identifies a user, a reading device 2A that acquires the authentication identification information from the portable terminal 1A through a first wireless communication, and an authentication device 4A that performs entry / exit authentication of the user using the authentication identification information acquired by the reading device 2A. The reading device 2A includes a reading device control unit that notifies the portable terminal 1A of first information including a first wireless communication method, which is a plurality of wireless communication methods that the reading device 2A can support, and the portable terminal 1A includes a portable terminal control unit that uses the first information acquired from the reading device control unit and second information including a second wireless communication method, which is a wireless communication method that the portable terminal 1A can support, to determine a fourth wireless communication method to be used for the first wireless communication from a third wireless communication method, which is a wireless communication method common to the first information and the second information, and notifies the reading device 2A of fourth information, which is information indicating the fourth wireless communication method. With this configuration, in a situation where the entrance / exit management system 100A equipped with a plurality of authentication methods using wireless communication methods is used, an appropriate authentication method can be selected from the plurality of authentication methods.

[0098] FIG. 10 shows a sequence diagram illustrating the process performed between the mobile terminal 1B and the reader 2B. The sequence diagram shown in FIG. 10 shows a process for determining which wireless communication method is to be used in wireless communication between the portable terminal 1B and the reader 2B during entrance and exit authentication in the entrance and exit management system 100B.

[0099] First, the control unit 20B notifies the mobile terminal 1B of first information, which is information indicating the reader identification information, by a predetermined wireless communication method (step ST501). Here, the first information may be notified periodically, or may be notified when requested by the mobile terminal 1B.

[0101] Then, the control unit 12B notifies the reading device 2B of the fourth information, which is information indicating the fourth wireless communication method, via a predetermined wireless communication method (step ST503).

[0102] Then, the control unit 12B notifies the user of the fourth information via the output unit 11B (step ST504).

[0103] Then, in the entrance / exit management system 100B, wireless communication is performed between the portable terminal 1B and the reader 2B for entrance / exit authentication using the fourth wireless communication method (steps ST505 and ST506).

[0104] Here, a specific example will be given for the sequence diagram shown in FIG. 9, the 31st wireless communication method is UWB, the 32nd wireless communication method is BLE, and the 33rd wireless communication method is NFC.

[0105] FIG. 11 shows a flow chart illustrating the process carried out between the mobile terminal 1B and the reader 2B in step ST502 of FIG.

[0106] First, the wireless communication method determination unit 17B uses the reader identification table to extract the first wireless communication method corresponding to the reader identification information acquired from the reader 2B (step ST601).

[0107] Then, the wireless communication method determination unit 17B uses the extracted information and the second information to determine a third wireless communication method common to the extracted information and the second information (step ST602).

[0108] Then, the wireless communication system determination unit 17B judges whether the third wireless communication system is a single system or a plurality of systems (step ST603).

[0109] Then, if there is only one third wireless communication method (YES in step ST603), the wireless communication method determination unit 17B sets the third wireless communication method as the fourth wireless communication method (step ST604).

[0110] Then, if there are multiple third wireless communication methods (if step ST603 is NO), the wireless communication method decision unit 17B uses the priority table to determine the wireless communication method with the highest priority as the fourth wireless communication method (step ST605).

[0111] Then, the output section 11B notifies the user of the fourth information (step ST606).

[0112] The entrance / exit management system 100B of this embodiment includes a portable terminal 1B that holds authentication identification information that is information for identifying a user, a reader 2B that acquires the authentication identification information from the portable terminal 1B by a first wireless communication, and an authentication device 4B that performs entrance / exit authentication of the user using the authentication identification information acquired by the reader 2B.

The portable terminal control unit holds a reader identification table corresponding to the communication method, extracts a first wireless communication method corresponding to the reader identification information acquired from the reader 2B using the reader identification table, and determines one fourth wireless communication method, which is a wireless communication method used for the first wireless communication, from the third wireless communication method, which is a wireless communication method common to the extracted information and the second information, using the extracted information, which is the first wireless communication method, and the second information including the second wireless communication method, which is a wireless communication method compatible with the portable terminal 1B, and notifies the reader 2B of the fourth information, which is information indicating the fourth wireless communication method. With such a configuration, it is possible to achieve the same effect as that described in the first embodiment. Here, the portable terminal control unit corresponds to the control unit 12B, and the reader control unit corresponds to the control unit 20B. The first wireless communication corresponds to wireless communication between the portable terminal 1B and the reader 2B, which is performed when the reader 2B acquires authentication identification information from the portable terminal 1B.

[0113] Embodiment 3 The entrance and exit control system 100C according to this embodiment will be described. In the first embodiment, a configuration was described in which the authentication device 4A performs entry / exit authentication of a user using the authentication identification information acquired by the reading device 2A. However, in this embodiment, the radio wave strength measurement unit 26C measures the radio wave strength of the fourth wireless communication method, the radio wave strength judgment unit 27C compares the radio wave strength measured by the radio wave strength measurement unit 26C with a predetermined threshold, and based on the judgment result, decides whether or not the authentication device 4C will perform entry / exit authentication. This is different from the first embodiment.

[0114] The entrance / exit management system 100C of this embodiment will be described with reference to FIG. The entrance and exit management system 100C includes a mobile terminal 1C, a plurality of reading devices 2C-1 to 2C-n, a plurality of electronic locks 3C-1 to 3C-n, and an authentication device 4C. The entrance / exit management system 100C is installed in a building, a facility, etc. In the entrance / exit management system 100C, a portable terminal 1C that holds recognition identification information, which is information for identifying a user of a building, facility, etc., communicates wirelessly with a reader 2C, whereby the reader 2C acquires authentication identification information from the portable terminal 1C, and an authentication device 4C performs entrance / exit authentication of the user using the authentication identification information acquired by the reader 2C.

[0115] The mobile terminal 1C includes an input unit 10C, an output unit 11C, a control unit 12C, a storage unit 13C, a first wireless communication unit 14C, a second wireless communication unit 15C, and a third wireless communication unit 16C. Furthermore, the control unit 12C includes a wireless communication method determination unit 17C.

[0116] The reading device 2C includes a control unit 20C, a storage unit 21C, an authentication device I / F unit 22C, a first wireless communication unit 23C, a second wireless communication unit 24C, and a third wireless communication unit 25C.

[0117] The authentication device 4C includes a control unit 40C, a storage unit 41C, reading device I / F units 42C-1 to 42C-n, and electronic lock I / F units 43C-1 to 43C-n. Furthermore, the control unit 40C includes an entry / exit authentication unit 44C.

[0118] In this embodiment, the control unit 40C further includes a radio wave intensity measurement unit 26C and a radio wave intensity judgment unit 27C. In the following description, the radio wave intensity measurement unit 26C, the radio wave intensity judgment unit 27C, an output unit 11C with additional functions compared to the configuration of the first embodiment, and a control unit 40C will be described. The other configurations and operations are the same as those of the first embodiment.

[0119] The output unit 11C notifies the user of the authentication identification information, the fourth wireless communication method, and other notification contents based on the judgment result acquired from the radio wave intensity judgment unit 27C. Here, the information based on the judgment result acquired from the radio wave intensity judgment unit 27C includes information that prompts the user to move closer to the reading device 2C when the measurement result is less than a predetermined threshold. In this embodiment, an example has been shown in which the output unit 11C notifies the user of the authentication identification information, the fourth wireless communication method, and other notification contents based on the judgment result acquired from the radio wave intensity judgment unit 27C, but the notification of the authentication identification information, the fourth wireless communication method, and other information based on the judgment result acquired from the radio wave intensity judgment unit 27C to the user is not essential and may not be notified.

[0120] The radio wave intensity measurement unit 26C measures the radio wave intensity of the fourth wireless communication method when the reader 2C acquires the authentication identification information from the portable terminal 1C. Then, it outputs the measurement result to the radio wave intensity judgment unit 27C. Note that, since the radio wave intensity measurement unit 26C periodically receives radio waves of the fourth wireless communication method, it may measure the radio wave intensity of the radio waves received multiple times and use the average value or the representative value of the radio wave intensity as the measurement result.

[0121] The radio wave intensity judgment unit 27C compares the measurement result output by the radio wave intensity measurement unit 26C with a predetermined threshold. Then, the radio wave intensity judgment unit 27C outputs the judgment result to the output unit 11C via the fourth wireless communication method. Furthermore, the radio wave intensity judgment unit 27C also outputs the judgment result to the control unit 40C via the authentication device I / F unit 22C. Here, the judgment result includes whether or not the measurement result is equal to or greater than the predetermined threshold. Furthermore, the predetermined threshold is appropriately set depending on the installation environment of the door, the reading device 2C, etc. in the entrance and exit management system 100C.

[0122] Usually, a person who intends to enter or leave a building, facility, etc. is considered to approach the reading device 2C intentionally for the entrance / exit authentication, whereas a person who does not intend to enter or leave a building, facility, etc. is considered to approach the reading device 2C intentionally less because there is no need for the entrance / exit authentication. In other words, it is considered that the radio wave intensity measured by the radio wave intensity measuring unit 26C tends to be stronger in wireless communication between the portable terminal 1C carried by a person who intends to enter or leave a building, facility, etc. and the reading device 2C compared to the portable terminal 1C carried by a person who does not intend to enter or leave a building, facility, etc. Therefore, by appropriately setting a predetermined threshold value according to the installation environment of the door, the reading device 2C, etc. in the entrance / exit management system 100C, it is possible to distinguish between a person who intends to enter or leave a building, facility, etc. and a person who does not intend to enter or leave a building, facility, etc.

[0123] Control unit 40C determines whether or not to perform entry / exit authentication using the judgment result obtained from radio wave intensity judgment unit 27C. Specifically, if the measurement result is equal to or greater than a predetermined threshold, entry / exit authentication unit 44C performs entry / exit authentication, and if the measurement result is less than the predetermined threshold, entry / exit authentication unit 44C does not perform entry / exit authentication.

[0124] The process of determining whether or not to perform entry / exit authentication based on the measurement result of radio wave intensity is described with reference to a flowchart in Fig. 13. The flowchart shown in Fig. 13 is performed between steps ST402 and ST403 in the flowchart shown in Fig. 7. The flowchart shown in Fig. 13 ends when radio waves are no longer received from the same reader 2C.

[0125] First, the radio wave intensity measuring unit 26C measures the radio wave intensity of the fourth wireless communication method when the reader 2C acquires the authentication identification information from the portable terminal 1C (step ST701).

[0126] Then, radio wave intensity determining section 27C compares the measurement result outputted by radio wave intensity measuring section 26C with a predetermined threshold value (step ST702).

[0127] If the measurement result is equal to or greater than a predetermined threshold value (YES in step ST702), the entry / exit authentication unit 44C performs entry / exit authentication (step ST703).

[0128] If the measurement result is less than a predetermined threshold value (NO in step ST702), entry / exit authentication section 44C does not perform entry / exit authentication (step ST704).

[0129] Then, after step ST704, the output unit 11C notifies the user of information based on the judgment result acquired from the radio wave intensity judgment unit 27C, including information prompting the user to get closer to the reader 2C (step ST705). Specifically, the output unit 11C notifies the user of information prompting the user to get closer to the reader 2C.

[0130] The entry / exit management system 100C of this embodiment includes a portable terminal 1C that holds authentication identification information, which is information that identifies a user, a reading device 2C that acquires the authentication identification information from the portable terminal 1C through a first wireless communication, and an authentication device 4C that performs entry / exit authentication of the user using the authentication identification information acquired by the reading device 2C. The reading device 2C includes a reading device control unit that notifies the portable terminal 1C of first information including a first wireless communication method, which is a plurality of wireless communication methods that the reading device 2C can support, and the portable terminal 1C includes a portable terminal control unit that uses the first information acquired from the reading device control unit and second information including a second wireless communication method, which is a wireless communication method that the portable terminal 1C can support, to determine a fourth wireless communication method to be used for the first wireless communication from a third wireless communication method, which is a wireless communication method common to the first information and the second information, and notifies the reading device 2C of fourth information, which is information indicating the fourth wireless communication method. The reading device control unit includes a radio wave intensity measurement unit 26C that measures the radio wave intensity of the fourth wireless communication method when the authentication identification information is acquired from the portable terminal 1C, and a radio wave intensity judgment unit 27C that compares the radio wave intensity with a predetermined threshold value. When the radio wave intensity judgment unit 27C judges that the radio wave intensity measured by the radio wave intensity measurement unit 26C is equal to or greater than the threshold value, the authentication device 4C performs the entry / exit authentication. When the radio wave intensity judgment unit 27C judges that the radio wave intensity measured by the radio wave intensity measurement unit 26C is less than the threshold value, the authentication device 4C does not perform the entry / exit authentication. With this configuration, in addition to the effects described in the first embodiment, it is possible to distinguish between a person who intends to enter or leave a building, facility, etc. and a person who does not intend to enter or leave a building, facility, etc. Therefore, it is possible to avoid a situation in which entry / exit authentication is performed on a person who does not intend to enter or leave a building, facility, etc., a history of entry or exit of a person who does not intend to enter or leave a building, facility, etc., and a history different from the actual situation remains in the entry / exit management system 100C. As a result, the user can appropriately use the entrance and exit management system 100C. Here, the mobile terminal control unit corresponds to the control unit 12C, and the reading device control unit corresponds to the control unit 20C. The first wireless communication corresponds to the wireless communication between the mobile terminal 1C and the reading device 2C that is performed when the reading device 2C obtains authentication identification information from the mobile terminal 1C.

[0131] Furthermore, the entrance / exit management system 100C of this embodiment notifies the user of information based on the judgment result obtained from the radio wave intensity judgment unit, including information prompting the user to get closer to the reading device 2C. Therefore, the user can act appropriately depending on whether or not he / she intends to enter or leave a building, facility, etc.

[0132] In this embodiment, the combination of the radio wave intensity measurement unit 26C and the radio wave intensity judgment unit 27C, which are configurations unique to this embodiment, with embodiment 1 has been described. However, the radio wave intensity measurement unit 26C and the radio wave intensity judgment unit 27C, which are configurations unique to this embodiment, may also be combined with embodiment 2.

[0133] In the present embodiment, it has been described that the radio wave intensity measurement unit 26C measures the radio wave intensity of the fourth wireless communication method when the reader 2C acquires the authentication identification information from the portable terminal 1C, and the radio wave intensity judgment unit 27C compares the measurement result output by the radio wave intensity measurement unit 26C with a predetermined threshold value, but it is not necessary to operate the radio wave intensity measurement unit 26C and the radio wave intensity judgment unit 27C in all wireless communication methods determined as the fourth wireless communication method. For example, it may be set whether or not to operate the radio wave intensity measurement unit 26C and the radio wave intensity judgment unit 27C depending on the type of wireless communication method, such as operating the radio wave intensity measurement unit 26C and the radio wave intensity judgment unit 27C when BLE is determined as the fourth wireless communication method.

[0134] Embodiment 4 An entrance / exit control system 100D according to this embodiment will be described. In the first embodiment, a configuration was described in which the authentication device 4A performs entry / exit authentication of a user using the authentication identification information acquired by the reading device 2A. However, in this embodiment, the motion detection unit 26D detects a predetermined motion of the user, and based on the detection result, the authentication device 4D decides whether or not to perform entry / exit authentication. This is different from the first embodiment.

[0135] The entrance / exit management system 100D of this embodiment will be described with reference to FIG. The entrance and exit management system 100D includes a mobile terminal 1D, a plurality of reading devices 2D-1 to 2D-n, a plurality of electronic locks 3D-1 to 3D-n, and an authentication device 4D. The entrance / exit management system 100D is installed in a building, a facility, etc. In the entrance / exit management system 100D, a portable terminal 1D that holds recognition identification information, which is information for identifying a user of a building, facility, etc., communicates wirelessly with a reader 2D, and the reader 2D acquires authentication identification information from the portable terminal 1D, and an authentication device 4D performs entrance / exit authentication of the user using the authentication identification information acquired by the reader 2D.

[0136] The mobile terminal 1D includes an input unit 10D, an output unit 11D, a control unit 12D, a storage unit 13D, a first wireless communication unit 14D, a second wireless communication unit 15D, and a third wireless communication unit 16D. Furthermore, the control unit 12D includes a wireless communication method determination unit 17D.

[0137] The reading device 2D includes a control unit 20D, a storage unit 21D, an authentication device I / F unit 22D, a first wireless communication unit 23D, a second wireless communication unit 24D, and a third wireless communication unit 25D.

[0138] The authentication device 4D includes a control unit 40D, a storage unit 41D, reading device I / F units 42D-1 to 42D-n, and electronic lock I / F units 43D-1 to 43D-n. The control unit 40D further includes an entry / exit authentication unit 44D.

[0139] In this embodiment, the control unit 40D further includes a motion detection unit 26D. In the following description, the motion detection unit 26D, and the output unit 11D and control unit 40D that have additional functions compared to the configuration of embodiment 1 will be described. The other configurations and operations are the same as those of embodiment 1.

[0140] The output unit 11D notifies the user of the authentication identification information, the fourth wireless communication method, and other notification contents based on the detection result acquired from the motion detection unit 26D. Here, the information based on the detection result acquired from the motion detection unit 26D includes information that prompts the user to move closer to the reading device 2D when the motion detection unit 26D does not detect a predetermined motion of the user. Note that, in the present embodiment, an example has been shown in which the output unit 11D notifies the user of the authentication identification information, the fourth wireless communication method, and other notification contents based on the detection result acquired from the motion detection unit 26D, but notification of the authentication identification information, the fourth wireless communication method, and other information based on the detection result acquired from the motion detection unit 26D to the user is not essential and may not be notified.

[0141] The motion detection unit 26D is composed of an infrared sensor, a camera, etc., and detects a predetermined motion of the user. Then, the detection result is output to the control unit 40D via the authentication device I / F unit 22D. The detection result includes information on whether or not the predetermined motion of the user has been detected.

[0142] Here, the predetermined motion of the user is a motion of holding a part of the user's body, such as a hand, over the motion detection unit 26D, a motion of the user turning his / her face toward the motion detection unit 26D, etc. Normally, when motion detection is required for entry / exit authentication, a person who intends to enter / exit a building, facility, etc. is considered to respond to a request to perform a predetermined motion, whereas a person who does not intend to enter / exit a building, facility, etc. is considered not to respond to a request to perform a predetermined motion because entry / exit authentication is not required. In other words, the motion detection unit 26D detects the predetermined motion to distinguish between a person who intends to enter / exit a building, facility, etc. and a person who does not intend to enter / exit a building, facility, etc.

[0143] The predetermined user action is intended to distinguish between a person who intends to enter or leave a building, facility, etc. and a person who does not intend to enter or leave a building, facility, etc., and is not limited to the action of holding part of the user's body over the action detection unit 26D or the action of the user turning their face towards the action detection unit 26D, and is set appropriately depending on the usage environment of the entry / exit management system 100D, etc.

[0144] The control unit 40D determines whether or not to perform entry / exit authentication using the detection result obtained from the motion detection unit 26D. Specifically, when the motion detection unit 26D detects a predetermined motion of the user, the entry / exit authentication unit 44D performs entry / exit authentication, and when the motion detection unit 26D does not detect the predetermined motion of the user, the entry / exit authentication unit 44D does not perform entry / exit authentication.

[0145] The process of determining whether or not to perform entry / exit authentication based on the detection result of a predetermined user behavior is described with reference to a flowchart in Fig. 15. The flowchart shown in Fig. 15 is performed between steps ST402 and ST403 in the flowchart shown in Fig. 7. The flowchart shown in Fig. 15 ends when a predetermined user behavior is not detected for a predetermined time or longer.

[0146] First, the motion detection unit 26D detects a predetermined motion of the user (step ST801).

[0147] Then, when the motion detection unit 26D detects a predetermined motion of the user (YES in step ST801), the entry / exit authentication unit 44D performs entry / exit authentication (step ST802).

[0148] If the motion detection unit 26D does not detect the predetermined motion of the user (NO in step ST801), the entry / exit authentication unit 44D does not perform entry / exit authentication (step ST803).

[0149] Then, following step ST803, the output section 11D notifies the user of information based on the detection result acquired from the motion detection section 26D, including information urging the user to move closer to the reading device 2D (step ST804).

[0150] The entry / exit management system 100D of this embodiment includes a portable terminal 1D that holds authentication identification information, which is information that identifies a user, a reading device 2D that acquires the authentication identification information from the portable terminal 1D through a first wireless communication, and an authentication device 4D that performs entry / exit authentication of the user using the authentication identification information acquired by the reading device 2D, wherein the reading device 2D includes a reading device control unit that notifies the portable terminal 1D of first information including a first wireless communication method, which is a plurality of wireless communication methods that the reading device 2D can support, and the portable terminal 1D includes a portable terminal control unit that uses the first information acquired from the reading device control unit and second information including a second wireless communication method, which is a wireless communication method that the portable terminal 1D can support, to determine a fourth wireless communication method to be used for the first wireless communication from a third wireless communication method, which is a wireless communication method common to the first information and the second information, and notifies the reading device 2D of fourth information, which is information indicating the fourth wireless communication method. The reading device control unit includes a motion detection unit 26D that detects a predetermined motion of the user. When the motion detection unit 26D detects a motion, the authentication device 4D performs entry / exit authentication. When the motion detection unit 26D does not detect a motion, the authentication device 4D does not perform entry / exit authentication. With this configuration, in addition to the effects described in the first embodiment, it is possible to distinguish between a person who intends to enter or leave a building, facility, etc. and a person who does not intend to enter or leave a building, facility, etc. Therefore, it is possible to avoid a situation in which entry / exit authentication is performed for a person who does not intend to enter or leave a building, facility, etc., a history of entry or exit of a person who does not intend to enter or leave a building, facility, etc., and a history different from the actual situation remains in the entry / exit management system 100D. As a result, the user can appropriately use the entry / exit management system 100D. Here, the mobile terminal control unit corresponds to the control unit 12D, and the reading device control unit corresponds to the control unit 20D. The first wireless communication corresponds to wireless communication between the portable terminal 1D and the reader 2D, which is performed when the reader 2D obtains authentication identification information from the portable terminal 1D.

[0151] Furthermore, the entrance and exit management system 100D of this embodiment notifies the user of information based on the detection result acquired from the motion detection unit 26D, including information prompting the user to approach closer to the motion detection unit 26D. Therefore, the user can act appropriately depending on whether or not the user intends to enter or leave a building, facility, or the like.

[0152] In the present embodiment, the combination of the motion detection unit 26D, which is a configuration unique to the present embodiment, and the first embodiment has been described. However, the motion detection unit 26D, which is a configuration unique to the present embodiment, may also be combined with the second embodiment.

[0153] In the present embodiment, the motion detector 26D detects a predetermined motion of a user, but it is not necessary to operate the motion detector 26D in all wireless communication methods determined as the fourth wireless communication method. For example, it may be set whether or not to operate the motion detector 26D depending on the type of wireless communication method, such as operating the motion detector 26D only when BLE is determined as the fourth wireless communication method.

[0154] Embodiment 5. An entrance / exit management system 100E according to this embodiment will be described. In the first embodiment, the wireless communication method determination unit 17A has been described as determining one of the third wireless communication methods, the fourth wireless communication method, which is a wireless communication method used for the first wireless communication. In the present embodiment, when there are a plurality of third wireless communication methods and when the third wireless communication methods include a fifth wireless communication method, which is a predetermined wireless communication method, the wireless communication method determination unit 17E determines a wireless communication method different from the fifth wireless communication method as the fourth wireless communication method. Then, the portable terminal 1E and the reading device 2E perform the first wireless communication using the fourth wireless communication method, as in the first embodiment. In addition, the portable terminal 1E and the reading device 2E perform the second wireless communication using the fifth wireless communication method, which is different from the first embodiment.

[0155] Here, the first wireless communication corresponds to wireless communication between the portable terminal 1E and the reader 2E, which is performed when the reader 2E acquires authentication identification information from the portable terminal 1E. The second wireless communication corresponds to wireless communication between the portable terminal 1E and the reader 2E, which is performed when the position information acquisition unit 18E acquires position information of the portable terminal 1E. Details will be described below.

[0156] The entrance / exit management system 100E of this embodiment will be described with reference to FIG. The entrance and exit management system 100E includes a mobile terminal 1E, a plurality of reading devices 2E-1 to 2E-n, a plurality of electronic locks 3E-1 to 3E-n, and an authentication device 4E. The entrance / exit management system 100E is installed in a building, a facility, etc. In the entrance / exit management system 100E, a portable terminal 1E that holds recognition identification information, which is information for identifying a user of a building, facility, etc., communicates wirelessly with a reader 2E, and the reader 2E acquires authentication identification information from the portable terminal 1E, and an authentication device 4E performs entrance / exit authentication of the user using the authentication identification information acquired by the reader 2E.

[0157] The mobile terminal 1E includes an input unit 10E, an output unit 11E, a control unit 12E, a storage unit 13E, a first wireless communication unit 14E, a second wireless communication unit 15E, and a third wireless communication unit 16E. Furthermore, the control unit 12E includes a wireless communication method determination unit 17E, a location information acquisition unit 18E, and an area determination unit 19E.

[0158] The reading device 2E includes a control unit 20E, a storage unit 21E, an authentication device I / F unit 22E, a first wireless communication unit 23E, a second wireless communication unit 24E, and a third wireless communication unit 25E.

[0159] The authentication device 4E includes a control unit 40E, a storage unit 41E, reading device I / F units 42E-1 to 42E-n, and electronic lock I / F units 43E-1 to 43E-n. Furthermore, the control unit 40E includes an entry / exit authentication unit 44E.

[0160] In this embodiment, a control unit 12E further includes a location information acquisition unit 18E and an area determination unit 19E in addition to the configuration of embodiment 1. In the following description, the location information acquisition unit 18E, the area determination unit 19E, and an output unit 11E, a wireless communication method determination unit 17E, and a control unit 40E, which have additional functions compared to the configuration of embodiment 1, will be described. The other configurations and operations are the same as those of embodiment 1.

[0161] The output unit 11E notifies the user of notification contents such as the authentication identification information, the fourth wireless communication method, the fifth wireless communication method, and information based on the determination result acquired from the area determination unit 19E. Here, the information based on the determination result acquired from the area determination unit 19E includes information that urges the user to move closer to the reading device 2E when the area determination unit 19E determines that the location information of the portable terminal 1E is not included in a predetermined area. In this embodiment, an example has been shown in which the output unit 11E notifies the user of notification contents such as the authentication identification information, the fourth wireless communication method, the fifth wireless communication method, and information based on the determination result obtained from the area determination unit 19E, but notification of the authentication identification information, the fourth wireless communication method, the fifth wireless communication method, and information based on the determination result obtained from the area determination unit 19E to the user is not essential and may not be required.

[0162] The wireless communication method determination unit 17E uses the first information indicating the first wireless communication method, the second information indicating the second wireless communication method, and the priority table to determine which wireless communication method is to be used in the first wireless communication and the second wireless communication between the portable terminal 1E and the reader 2E in the entrance / exit authentication. Details will be described later.

[0163] The position information acquisition unit 18E acquires the position information of the mobile terminal 1E (hereinafter, the position information of the mobile terminal 1E is referred to as the position information) by using the second wireless communication. Then, the position information acquisition unit 18E outputs the position information to the area determination unit 19E.

[0164] The area determination unit 19E determines whether or not the location information acquired from the location information acquisition unit 18E is included in a predetermined area. Then, the area determination unit 19E outputs the determination result to the output unit 11E. Furthermore, the area determination unit 19E also outputs the determination result to the control unit 40E. Here, the determination result includes whether or not the location information is included in a predetermined area. Furthermore, the predetermined area is appropriately set to include the position of the reading device 2E. Furthermore, the predetermined area is appropriately set depending on the installation environment of the door, the reading device 2E, etc. in the entrance and exit management system 100E.

[0165] Usually, a person who intends to enter or leave a building, facility, etc. is considered to approach the reading device 2E intentionally for the entrance / exit authentication, whereas a person who does not intend to enter or leave a building, facility, etc. is considered to approach the reading device 2E intentionally less because there is no need for the entrance / exit authentication. In other words, compared with the location information of the portable terminal 1E held by a person who intends to enter or leave a building, facility, etc., the location information of the portable terminal 1E held by a person who intends to enter or leave a building, facility, etc. is considered to be located within a predetermined area. Therefore, by appropriately setting a predetermined area according to the installation environment of the door, the reading device 2E, etc. in the entrance / exit management system 100E, it is possible to distinguish between a person who intends to enter or leave a building, facility, etc. and a person who does not intend to enter or leave a building, facility, etc.

[0166] The control unit 40E determines whether or not to perform entry / exit authentication using the determination result obtained from the area determination unit 19E. Specifically, if the area determination unit 19E determines that the location information is included in a predetermined area, the entry / exit authentication unit 44E performs entry / exit authentication, and if the area determination unit 19E determines that the location information is not included in a predetermined area, the entry / exit authentication unit 44E does not perform entry / exit authentication.

[0167] Next, FIG. 17 shows a sequence diagram showing the process carried out between the portable terminal 1E and the reading device 2E. The sequence diagram shown in FIG. 17 shows a process for determining which wireless communication method to use in the first wireless communication and the second wireless communication between the portable terminal 1E and the reading device 2E during entry / exit authentication in the entry / exit management system 100E.

[0168] First, the control unit 20E notifies the mobile terminal 1E of first information, which is information indicating a first wireless communication method, by a predetermined wireless communication method (step ST901). Here, the first information may be notified periodically, or may be notified when requested by the mobile terminal 1E.

[0169] Then, the wireless communication method determination unit 17E uses the first information and the second information, which is information indicating the second wireless communication method, to determine a common wireless communication method common to the first information and the second information as a third wireless communication method. Furthermore, when there are a plurality of third wireless communication methods and when the third wireless communication method includes a fifth wireless communication method, which is a predetermined wireless communication method, the wireless communication method determination unit 17E determines a wireless communication method different from the fifth wireless communication method as a fourth wireless communication method. Specifically, the wireless communication method determination unit 17E determines the wireless communication method with the highest priority among the wireless communication methods excluding the fifth wireless communication method as the fourth wireless communication method using the priority table shown in FIG. 2 (step ST902).

[0170] Then, the control unit 12E notifies the reading device 2E of the fourth information indicating the fourth wireless communication method and the fifth information indicating the fifth wireless communication method via a predetermined wireless communication method (step ST903).

[0171] Then, the control unit 12E notifies the user of the fourth information and the fifth information via the output unit 11E (step ST904).

[0172] Then, the portable terminal 1E and the reader 2E perform the first wireless communication using the fourth wireless communication method and the second wireless communication using the fifth wireless communication method (step ST905 and step ST906).

[0173] Here, a specific example will be given for the sequence diagram shown in FIG. In this embodiment, the eleventh and twenty-first wireless communication methods are UWB, the twelfth and twenty-second wireless communication methods are BLE, the thirteenth and twenty-third wireless communication methods are NFC, and the fifth wireless communication method is UWB. That is, the second wireless communication method that is a wireless communication method that the portable terminal 1A can support is UWB, BLE, and NFC, and the first wireless communication method that is a wireless communication method that the reader 2A can support is also UWB, BLE, and NFC. In this case, through steps ST901 to ST906 shown in FIG. 17, the third wireless communication scheme is UWB, BLE, and NFC, the fourth wireless communication scheme is BLE, and the fifth wireless communication scheme is UWB.

[0174] Next, FIG. 18 shows a flow chart illustrating the process performed by the mobile terminal 1E in step ST902 of FIG.

[0175] First, the wireless communication method determination unit 17E uses the first information and the second information to determine a third wireless communication method common to the first information and the second information (step ST1001).

[0176] Then, the wireless communication method determination unit 17E determines whether the third wireless communication method is a single method or a plurality of methods (step ST1002).

[0177] Then, if there is a single third wireless communication method (YES in step ST1002), the wireless communication method determination unit 17E sets the third wireless communication method as the fourth wireless communication method (step ST1003).

[0178] Then, when there are a plurality of third wireless communication methods (NO in step ST1002), the wireless communication method decision unit 17E judges whether or not a fifth wireless communication method is included (step ST1004).

[0179] Then, if the fifth wireless communication method is included (if step ST1004 is YES), the wireless communication method determination unit 17E uses the priority table shown in FIG. 2 to determine the wireless communication method with the highest priority among the wireless communication methods excluding the fifth wireless communication method as the fourth wireless communication method (step ST1005).

[0180] Then, if the fifth wireless communication method is not included (if step ST1004 is NO), the wireless communication method determination unit 17E uses the priority table shown in FIG. 2 to determine the wireless communication method with the highest priority among the wireless communication methods as the fourth wireless communication method (step ST1006).

[0181] Then, the output unit 11E notifies the user of the fourth information and the fifth information (step ST1007).

[0182] Next, the process of determining whether or not to perform entry / exit authentication based on the determination result of area determination unit 19E will be described with reference to the flowchart in Fig. 19. The flowchart shown in Fig. 19 is performed between steps ST402 and ST403 in the flowchart shown in Fig. 7.

[0183] First, the location information acquisition unit 18E acquires the location information of the mobile terminal 1E by using the second wireless communication (step ST1101).

[0184] Then, the area determination unit 19E determines whether or not the location information acquired from the location information acquisition unit 18E is included in a predetermined area (step ST1102).

[0185] Then, if the location information is included in a predetermined area (if step ST1102 is YES), the entry / exit authentication unit 44E performs the entry / exit authentication (step ST1103).

[0186] Then, if the location information is not included in the predetermined area (if NO in step ST1102), entry / exit authentication unit 44E does not perform entry / exit authentication (step ST1104).

[0187] Then, after step ST1104, the output unit 11E notifies the user of information based on the determination result acquired from the area determination unit 19E, including information prompting the user to get closer to the reading device 2E (step ST1105). Specifically, the output unit 11E notifies the user of information prompting the user to get closer to the reading device 2E.

[0188] The entry / exit management system 100E of this embodiment includes a portable terminal 1E that holds authentication identification information, which is information that identifies a user, a reading device 2E that acquires the authentication identification information from the portable terminal 1E through a first wireless communication, and an authentication device 4E that performs entry / exit authentication of the user using the authentication identification information acquired by the reading device 2E, wherein the reading device 2E includes a reading device control unit that notifies the portable terminal 1E of first information including a first wireless communication method, which is a plurality of wireless communication methods that the reading device 2E can support, and the portable terminal 1E includes a portable terminal control unit that uses the first information acquired from the reading device control unit and second information including a second wireless communication method, which is a wireless communication method that the portable terminal 1E can support, to determine a fourth wireless communication method to be used for the first wireless communication from a third wireless communication method, which is a wireless communication method common to the first information and the second information, and notifies the reading device 2E of fourth information, which is information indicating the fourth wireless communication method. When there are a plurality of third wireless communication methods and when the third wireless communication method includes a fifth wireless communication method that is a predetermined wireless communication method, the mobile terminal control unit sets a wireless communication method different from the fifth wireless communication method as the fourth wireless communication method, and the mobile terminal and the reading device perform the second wireless communication using the fifth wireless communication method. With this configuration, in addition to the effects described in the first embodiment, it is possible to distinguish between a person who intends to enter or leave a building, facility, etc. and a person who does not intend to enter or leave a building, facility, etc. Therefore, it is possible to avoid a situation where entry and exit authentication is performed on a person who does not intend to enter or leave a building, facility, etc., and a history of entry or exit of a person who does not intend to enter or leave a building, facility, etc. is left, and a history different from the actual situation is left in the entry and exit management system 100E. As a result, the user can appropriately use the entry and exit management system 100E. Here, the mobile terminal control unit corresponds to the control unit 12E, and the reading device control unit corresponds to the control unit 20E.

[0189] Furthermore, the entrance / exit management system 100E of this embodiment notifies the user of information based on the determination result obtained from the area determination unit 19E, including information prompting the user to move closer to the reading device 2E. Therefore, the user can act appropriately depending on whether or not he / she intends to enter or leave a building, facility, etc.

[0190] In this embodiment, the combination of the location information acquisition unit 18E and the area determination unit 19E, which are configurations unique to this embodiment, with embodiment 1 has been described. However, the location information acquisition unit 18E and the area determination unit 19E, which are configurations unique to this embodiment, may also be combined with embodiment 2.

[0191] Embodiment 6 The entrance and exit control system 100F in this embodiment will be described. In the fifth embodiment, a configuration in which the position information acquisition unit 18E and the area determination unit 19E are provided in the control unit 12E has been described. In the present embodiment, the position information acquisition unit 26F and the area determination unit 27F are provided in the control unit 20A, which is different from the fifth embodiment. The rest of the configuration and operation are the same as those in the fifth embodiment.

[0192] The entrance / exit management system 100F of this embodiment will be described with reference to FIG. The entrance and exit management system 100F includes a mobile terminal 1F, a plurality of reading devices 2F-1 to 2F-n, a plurality of electronic locks 3F-1 to 3F-n, and an authentication device 4F. The entrance / exit management system 100F is installed in a building, a facility, etc. In the entrance / exit management system 100F, the reader 2F wirelessly communicates with a portable terminal 1F that holds recognition identification information, which is information for identifying a user of a building, facility, etc., so that the reader 2F acquires authentication identification information from the portable terminal 1F, and the authentication device 4F performs entrance / exit authentication of the user using the authentication identification information acquired by the reader 2F.

[0193] The mobile terminal 1F includes an input unit 10F, an output unit 11F, a control unit 12F, a storage unit 13F, a first wireless communication unit 14F, a second wireless communication unit 15F, and a third wireless communication unit 16F. Furthermore, the control unit 12F includes a wireless communication method determination unit 17F, a location information acquisition unit 26F, and an area determination unit 27F.

[0194] The reading device 2F includes a control unit 20F, a storage unit 21F, an authentication device I / F unit 22F, a first wireless communication unit 23F, a second wireless communication unit 24F, and a third wireless communication unit 25F.

[0195] The authentication device 4F includes a control unit 40F, a storage unit 41F, reading device I / F units 42F-1 to 42F-n, and electronic lock I / F units 43F-1 to 43F-n. The control unit 40F further includes an entry / exit authentication unit 44F.

[0196] The present embodiment differs from the configuration of embodiment 5 in that a location information acquisition unit 26F corresponding to location information acquisition unit 18E and an area determination unit 27F corresponding to area determination unit 19E are provided in a control unit 40F. In the following description, location information acquisition unit 26F, area determination unit 27F, and output unit 11F and control unit 40F whose functions are different from those of embodiment 5 will be described. Other configurations and operations are the same as those of embodiment 5.

[0197] The output unit 11F notifies the user of the notification contents such as the authentication identification information, the fourth wireless communication method, the fifth wireless communication method, and information based on the determination result acquired from the area determination unit 27F. Here, the information based on the determination result acquired from the area determination unit 27F includes information that prompts the user to move closer to the reading device 2F when the area determination unit 27F determines that the location information of the portable terminal 1F is not included in a predetermined area. In this embodiment, an example has been shown in which the output unit 11F notifies the user of notification contents such as the authentication identification information, the fourth wireless communication method, the fifth wireless communication method, and information based on the judgment result obtained from the area judgment unit 27F, but notification of the authentication identification information, the fourth wireless communication method, the fifth wireless communication method, and information based on the judgment result obtained from the area judgment unit 27F to the user is not mandatory and may not be required.

[0198] The position information acquisition unit 26F acquires the position information of the portable terminal 1F (hereinafter, the position information of the portable terminal 1F is referred to as the position information) using the second wireless communication. Then, the position information acquisition unit 26F outputs the position information to the area determination unit 27F.

[0199] The area determination unit 27F determines whether or not the location information acquired from the location information acquisition unit 26F is included in a predetermined area. Then, the area determination unit 27F outputs the determination result to the output unit 11F. Furthermore, the area determination unit 27F also outputs the determination result to the control unit 40F. Here, the determination result includes whether or not the location information is included in a predetermined area. Furthermore, the predetermined area is appropriately set to include the position of the reading device 2F. Furthermore, the predetermined area is appropriately set depending on the installation environment of the door, the reading device 2F, etc. in the entrance and exit management system 100F.

[0200] Usually, a person who intends to enter or leave a building, facility, etc. is considered to approach the reading device 2F intentionally for the entrance / exit authentication, whereas a person who does not intend to enter or leave a building, facility, etc. is considered to approach intentionally less because there is no need for the entrance / exit authentication. In other words, compared with the location information of a mobile terminal 1F carried by a person who intends to enter or leave a building, facility, etc., the location information of a mobile terminal 1F carried by a person who intends to enter or leave a building, facility, etc. is considered to be located within a predetermined area. Therefore, by appropriately setting a predetermined area according to the installation environment of the door, the reading device 2F, etc. in the entrance / exit management system 100F, a person who intends to enter or leave a building, facility, etc. can be distinguished from a person who does not intend to enter or leave a building, facility, etc.

[0201] The control unit 40F determines whether or not to perform entry / exit authentication using the determination result obtained from the area determination unit 27F. Specifically, if the area determination unit 27F determines that the location information is included in a predetermined area, the entry / exit authentication unit 44F performs entry / exit authentication, and if the area determination unit 27F determines that the location information is not included in a predetermined area, the entry / exit authentication unit 44F does not perform entry / exit authentication. Here, the process of determining whether or not to perform entry / exit authentication based on the determination result of the area determination unit 27F is the same as that in FIG. 19. This process is performed between steps ST402 and ST403 in the flowchart shown in FIG. 7.

[0202] The entry / exit management system 100F of this embodiment includes a portable terminal 1F that holds authentication identification information, which is information that identifies a user, a reading device 2F that acquires the authentication identification information from the portable terminal 1F via a first wireless communication, and an authentication device 4F that performs entry / exit authentication of the user using the authentication identification information acquired by the reading device 2F, wherein the reading device 2F includes a reading device control unit that notifies the portable terminal 1F of first information including a first wireless communication method, which is a plurality of wireless communication methods that the reading device 2F can support, and the portable terminal 1F includes a portable terminal control unit that uses the first information acquired from the reading device control unit and second information including a second wireless communication method, which is a wireless communication method that the portable terminal 1F can support, to determine a fourth wireless communication method to be used for the first wireless communication from a third wireless communication method, which is a wireless communication method common to the first information and the second information, and notifies the reading device 2F of fourth information, which is information indicating the fourth wireless communication method. When there are a plurality of third wireless communication methods and when the third wireless communication method includes a fifth wireless communication method that is a predetermined wireless communication method, the mobile terminal control unit sets a wireless communication method different from the fifth wireless communication method as the fourth wireless communication method, and the mobile terminal and the reading device perform the second wireless communication using the fifth wireless communication method. With this configuration, in addition to the effects described in the first embodiment, it is possible to distinguish between a person who intends to enter or leave a building, facility, etc. and a person who does not intend to enter or leave a building, facility, etc. Therefore, it is possible to avoid a situation where entry / exit authentication is performed on a person who does not intend to enter or leave a building, facility, etc., and a history of entry or exit of a person who does not intend to enter or leave a building, facility, etc. is left, and a history different from the actual situation is left in the entry / exit management system 100F. As a result, the user can appropriately use the entry / exit management system 100F. Here, the mobile terminal control unit corresponds to the control unit 12F, and the reading device control unit corresponds to the control unit 20F.

[0203] Furthermore, the entrance / exit management system 100F of this embodiment notifies the user of information based on the determination result obtained from the area determination unit 27F, including information prompting the user to move closer to the reading device 2F. Therefore, the user can act appropriately depending on whether or not he / she intends to enter or leave a building, facility, etc.

[0204] In this embodiment, the combination of the location information acquisition unit 26F and the area determination unit 27F, which are configurations unique to this embodiment, with embodiment 1 has been described. However, the location information acquisition unit 26F and the area determination unit 27F, which are configurations unique to this embodiment, may also be combined with embodiment 2.
