The BT beacon ID "001" identifies the BT beacon transmitting device 72A, and the BT beacon ID "002" identifies the BT beacon transmitting device 72B. The address information is the IP address of the multifunction device 71 on the communication network. The address information "192.168.0.101" is the IP address of the multifunction device 71A, and the address information "192.168.0.102" is the IP address of the multifunction device 71B.

The IP address of the multifunction device 71A installed in the room 113 is associated with the BT beacon ID of the BT beacon transmitting device 72A installed in the same room 113. Similarly, the IP address of the multifunction device 71B installed in the room 114 is associated with the BT beacon ID of the BT beacon transmitting device 72B installed in the same room 114.

Further, as shown in FIG. 3C, the data storage area 62B can store the terminal ID and the path information associated with the terminal ID. The terminal ID "term01" is an example of terminal identification information that identifies the mobile terminal 10. The path information is information indicating the location of a storage area accessible to the mobile terminal 10 in the storage device 73. The NFC reader 50A collects various information shown in FIG. 3C in the process shown in FIG. 4, for example.

As shown in FIG. 1, the NFC reader 50B is arranged inside the building 110 and in the vicinity of the doorway 111. Since the polling signal transmitted by the direct communication unit 56 of the NFC reader 50B reaches only within a very limited distance range, it can be received inside the building 110 and near the doorway 111, and can be received in the rooms 113 and 114 and in the rooms 113 and 114. It cannot be received outside the building 110. The control program 65 of the NFC reader 50B causes the communication unit 56 to repeatedly send a polling signal at predetermined time intervals. The NFC reader 50B is an example of the second transmission device.

The BT beacon transmitting device 72 repeatedly transmits a bluetooth LE-compliant beacon signal (hereinafter, referred to as “BT beacon”) at predetermined time intervals. The BT beacon includes a BT beacon ID that identifies the BT beacon transmitting devices 72A, 72B. The BT beacon transmitting device 72A is arranged in the same room 113 as the multifunction device 71A. Then, since the BT beacon transmitted by the BT beacon transmitting device 72A does not reach within a predetermined range, it can be received in the room 113 and cannot be received in the room 114. Alternatively, the BT beacon is received with a very weak radio field strength even if it can be received in the room 114.

Further, the BT beacon transmitting device 72A may be able to adjust the radio field intensity of the BT beacon to be transmitted. With such a configuration, the installer of the BT beacon transmitting device 72A can receive the radio field strength of the BT beacon transmitting device 72A installed in the room 113 in the room 113, and cannot receive it in the room 114. It can be adjusted to strength.

The BT beacon transmitting device 72B is arranged in the same room 114 as the multifunction device 71B. Then, the BT beacon transmitted by the BT beacon transmitting device 72B can be received in the room 114 and cannot be received in the room 113. Alternatively, the BT beacon is received with a very weak radio field strength even if it can be received in the room 113. Similar to the BT beacon transmitting device 72A, the BT beacon transmitting device 72B may be able to set the radio wave intensity when outputting the BT beacon.

The multifunction device 71A and the BT beacon transmitting device 72A installed in the same room 113 may be configured as separate bodies or integrally as shown in FIG. Similarly, the multifunction device 71B and the BT beacon transmitting device 72B installed in the same room 113 may be configured as separate bodies or integrally as shown in FIG. Further, the multifunction device 71 including the BT beacon transmission device 72 transmits, for example, the BT beacon ID of the BT beacon transmission device 72 and the IP address of the multifunction device 71 to the NFC reader 50A in response to a request from the NFC reader 50A. You may.

[Storage device 73]
The storage device 73 has a storage area accessible to the mobile terminal 10 through a communication network. When the storage device 73 is requested to read the data from the mobile terminal 10 through the communication network, the storage device 73 transmits the data stored in the storage area to the mobile terminal 10 through the communication network. When the storage device 73 requests the writing of data from the mobile terminal 10 through the communication network, the storage device 73 writes the data received from the mobile terminal 10 through the communication network to the storage area. Further, the storage device 73 can make access settings that limit the mobile terminals 10 that can access each storage area. The installation location of the storage device 73 is not particularly limited as long as it is connected to the communication network. The storage device 73 is an example of an information sharing device.

[Operation of communication system 100]
The operation of the communication system 100 will be described with reference to FIGS. 4 to 6. The communication system 100 according to the present embodiment manages the entry and exit of the user who owns the mobile terminal 10 to and from the building 110, and allows the user who enters the building 110 through the entrance and exit 111 to enter the multifunction device 71 and the storage through the mobile terminal 10. A process for utilizing the device 73 is executed. At the start of the operation described below, the door of the doorway 111 is in the locked state.

First, the control program 65 of the NFC reader 50A arranged outside the building 110 sends a beacon signal to the direct communication unit 56 in response to the power of the NFC reader 50A being turned on, as shown in FIG. Sending is started (S11). That is, the direct communication unit 56 of the NFC reader 50A repeatedly sends out polling signals at predetermined time intervals while the power is turned on. Further, the NFC reader 50B arranged inside the building 110 executes the processes of steps S11, S12, S15, and S16 among the processes shown in FIG.

A user who wants to enter the building 110 holds the mobile terminal 10 over the NFC reader 50A. In other words, the user brings the mobile terminal 10 closer to a distance where the polling signal transmitted by the NFC reader 50A can be received. Then, the direct communication unit 26 of the mobile terminal 10 receives the polling signal from the NFC reader 50A.

Next, the control program 35 of the mobile terminal 10 establishes an NFC link with the NFC reader 50 in response to receiving the polling signal through the direct communication unit 26 (S21: polling signal) (S22). Since the procedure for establishing the NFC link is already well known, detailed description thereof will be omitted. The process of step S21 is an example of the determination process.

Further, the control program 35 of the mobile terminal 10 provides the NFC reader 50 with the established NFC link with the terminal ID “term01” of the mobile terminal 10 and permission information indicating that the building 110 is permitted to enter. The response signal including the above is directly transmitted through the communication unit 26 (S23). The permission information is, for example, given to the mobile terminal 10 in advance by the manager of the building 110. For example, an NFC reader different from the NFC readers 50A and 50B may be installed near the gate of the site where the building 110 is installed. Then, the user of the mobile terminal 10 may make the mobile terminal 10 receive the permission information by holding the mobile terminal 10 over the NFC reader before entering the building 110.

Further, the control program 35 of the mobile terminal 10 determines whether the source of the received polling signal is the NFC readers 50A or 50B (S24). The control program 35 may determine, for example, the NFC readers 50A and 50B from which the polling signal is transmitted based on the identification information included in the received polling signal. The process of step S24 is another example of the determination process. Then, the control program 35 waits for the reception of the first radio signal through the direct communication unit 26 in response to the determination that the source of the polling signal is the NFC reader 50A (S24: first transmission device).

Alternatively, the control program 35 may determine the NFC readers 50A and 50B from which the polling signal is transmitted depending on whether or not the first radio signal including the communication information is received within a predetermined period after the transmission of the response signal. good. The NFC reader 50A transmits a first radio signal including communication information, and the NFC reader 50B does not transmit a first radio signal including communication information. Therefore, the control program 35 may determine that the source of the polling signal is the NFC reader 50A in response to receiving the first radio signal within a predetermined period. Further, the control program 35 may determine that the source of the polling signal is the NFC reader 50B, depending on whether the first radio signal is not received within a predetermined period.

Next, as shown in FIG. 4, the control program 65 of the NFC reader 50A receives a response signal from the mobile terminal 10 through the direct communication unit 56 (S12: Yes). Then, the control program 65 generates a storage area accessible to the mobile terminal 10 in the storage device 73 in response to receiving the response signal (S13). The storage area may be set to be accessible only by the mobile terminal 10 identified by the terminal ID "term01" among the devices that access the storage device 73 through the access point 70. Further, the control program 65 associates the path information “temp.term01” indicating the generated storage area with the terminal ID “term01” included in the response signal, and sets the data storage area 62B shown in FIG. 3 (C). Remember. Step S13 is an example of the generation process.

Next, the control program 65 of the NFC reader 50A directly transmits a first radio signal including communication information to the mobile terminal 10 for which the NFC link has been established (S14). The communication information included in the first radio signal corresponds to the SSID shown in FIG. 3 (B), the plurality of BT beacon IDs, the plurality of address information, and the terminal ID “term01” shown in FIG. 3 (C). Includes path information. The process of step S14 is an example of the first transmission process.

Next, the control program 65 of the NFC reader 50A changes the state of the door of the doorway 111 from the locked state to the unlocked state (S15). As a result, the user who possesses the mobile terminal 10 can open the door of the doorway 111 and enter the building 110. The process of step S15 is an example of the unlock process. Further, the door of the doorway 111 changes its state from the unlocked state to the locked state again according to the elapse of a predetermined time after the unlocking process is executed. This process may be executed by, for example, the NFC readers 50A and 50B, or may be executed by a control unit provided on the door of the doorway 111.

Then, the control program 65 of the NFC reader 50A disconnects the NFC link established with the mobile terminal 10 (S16). Alternatively, the process of disconnecting the NFC link may be executed by the mobile terminal 10 that has received the first radio signal. Since the procedure for disconnecting the NFC link is already well known, detailed description thereof will be omitted. Then, the control program 65 executes the processes after step S11 again. The processing order of steps S13 to S16 is not limited to the above-mentioned example. For example, the process of step S15 may be executed before step S13 or after step S16.

Next, as shown in FIG. 5, the control program 35 of the mobile terminal 10 receives the first radio signal from the NFC reader 50A having the NFC link established through the direct communication unit 26 (S25). The process of step S25 is an example of the first reception process and the acquisition process. Further, the control program 35 extracts communication information from the received first radio signal. Further, the control program 35 acquires timing information indicating the reception time of the first radio signal. Specifically, the control program 35 may receive timing information from a clock counter (not shown). Alternatively, the control program 35 may read the timing information written by the clock counter into the data storage area 32B from the data storage area 32B. Then, the control program 35 stores the extracted communication information and the acquired timing information in the data storage area 32B shown in FIG. 3A (S26).

Next, the control program 35 of the mobile terminal 10 sets the SSID included in the communication information in the Wi-Fi communication unit 25 (S27). The process of step S27 is an example of the setting process. As a result, the control program 35 can connect the Wi-Fi communication unit 25 to the access point 70. Further, the control program 35 of the mobile terminal 10 sets the BT beacon monitoring timer (S28). The BT beacon monitoring timer is for monitoring the time during which the BT beacon transmitted from the BT beacon transmitting device 72 cannot be received. The BT beacon monitoring timer times out in the first threshold time of about several tens of minutes to several hours.

In addition, "setting the SSID in the Wi-Fi communication unit 25" means that the SSID is set in a predetermined area of the storage unit 32 so that the Wi-Fi communication unit 25 can output a radio signal including the SSID. Refers to memorizing. Further, the process of connecting the Wi-Fi communication unit 25 to the access point 70 may be executed in step S27, or may be executed when actually accessing the multifunction device 71 or the storage device 73.

Next, the user possessing the mobile terminal 10 enters the building 110 through the doorway 111 and enters the room 113 through the doorway 115, for example. As a result, the control program 35 of the mobile terminal 10 receives the BT beacon from the BT beacon transmitting device 72A through the direct communication unit 26 (S11: BT beacon). The process in which the mobile terminal 10 receives the BT beacon is an example of the beacon reception process.

Next, the control program 35 extracts the BT beacon ID "001" from the BT beacon if the radio wave intensity of the received BT beacon is equal to or higher than a predetermined radio wave intensity. Then, the control program 35 sets the multifunction device 71A having the IP address “192.168.0.101” associated with the BT beacon ID “001” as the communication partner (S29). However, the control program 35 does not need to actually access the multifunction device 71A in step S29, and may store the multifunction device 71A as a communication partner when receiving a print instruction or a scan instruction described later. Further, the control program 35 resets the BT beacon monitoring timer (S30).

The control program 35 receives the BT beacon before executing step S29 when each of the received plurality of BT beacons has a predetermined radio wave intensity or higher and a different BT beacon ID is set for each. You may continue. Then, the control program 35 extracts the BT beacon ID from the BT beacon when there is only one BT beacon having a predetermined radio wave intensity or higher. Then, the control program 35 sets the multifunction device of the IP address associated with the BT beacon ID as the communication partner. By doing so, even if the BT beacon is received from the BT beacon transmitting device 72B installed in the room 114 when just entering and exiting the room 113, the multifunction device installed in the room 114 It is possible to prevent 71B from being mistakenly set as a communication partner.

As a result, the control program 35 of the mobile terminal 10 can access the multifunction device 71A and the storage device 73 through the access point 70. Further, the control program 35 receives a print instruction for causing the multifunction device 71A to execute the print process, a scan instruction for causing the multifunction device 71A to execute the scan process, a write instruction for storing the data in the storage device 73, and data from the storage device 73. The read instruction to be read can be received through the operation unit 24. Then, the control program 35 communicates with the multifunction device 71A and the storage device 73 connected to the communication network through the Wi-Fi communication unit 25 in which the SSID is set, based on various instructions received through the operation unit 24. The process in which the mobile terminal 10 communicates with the multifunction device 71 and the storage device 73 is an example of the communication process.

Specifically, the control program 35 that has received the print instruction transmits the print instruction information including the image data to be printed to the multifunction device 71A through the Wi-Fi communication unit 25. Further, the control program 35 that has received the scan instruction transmits the scan instruction information instructing the execution of the scan process to the multifunction device 71A through the Wi-Fi communication unit 25. Then, the control program 35 receives the image data generated by the scanning process from the multifunction device 71A through the Wi-Fi communication unit 25.

Further, the control program 35 that has received the write instruction transmits the write instruction information including the data to be stored to the storage device 73 through the Wi-Fi communication unit 25. Further, the control program 35 that has received the read instruction transmits the read instruction information including the data identification information of the data to be acquired to the storage device 73 through the Wi-Fi communication unit 25. Then, the control program 35 receives the data identified by the data identification information from the storage device 73 through the Wi-Fi communication unit 25.

Further, the user who is about to leave the building 110 holds the mobile terminal 10 over the NFC reader 50B. In other words, the user brings the mobile terminal 10 closer to a distance where the polling signal transmitted by the NFC reader 50B can be received. As a result, the direct communication unit 26 of the mobile terminal 10 receives the polling signal from the NFC reader 50B (S21: polling signal). The polling signal transmitted by the NFC reader 50B is an example of a second radio signal. The process in which the mobile terminal 10 receives the polling signal from the NFC reader 50B is an example of the second reception process. The reception of the polling signal from the NFC reader 50B is an example of a trigger instructing the cancellation of the SSID setting.

Further, the control program 35 of the mobile terminal 10 establishes an NFC link with the NFC reader 50 that sends out the polling signal (S22). Further, the control program 35 directly transmits a response signal, which is a response to the polling signal, to the NFC reader 50 to which the NFC link has been established (S23). Further, the control program 35 determines whether the source of the received polling signal is the NFC reader 50A or 50B (S24). The processes of steps S22 to S24 are common to both the NFC readers 50A and 50B.

Next, the control program 35 of the mobile terminal 10 determines that the source of the received polling signal is the NFC reader 50B (S24: second transmission device), and responds to the SSID for the Wi-Fi communication unit 25. Cancel the setting (S31). The process of step S31 is an example of the release process. Next, the control program 35 of the mobile terminal 10 deletes the communication information and the timing information from the data storage area 32B shown in FIG. 3A (S32). Further, the control program 35 releases the BT beacon monitoring timer (S33).

The phrase "cancel the SSID setting for the Wi-Fi communication unit 25" is defined in advance in the storage unit 32 so that the Wi-Fi communication unit 25 cannot output a radio signal including the SSID, for example. Refers to deleting the SSID stored in the area. As a result, the connection between the Wi-Fi communication unit 25 and the access point 70 is cut off. That is, the control program 35 of the mobile terminal 10 cannot access the multifunction device 71 and the storage device 73 through the Wi-Fi communication unit 25 thereafter. If the SSID stored in the predetermined area of the storage unit 32 is deleted, the mobile terminal 10 cannot connect to the access point 70 unless it communicates with the NFC reader 50A again.

Further, as shown in FIG. 4, the control program 65 of the NFC reader 50B receives a response signal from the mobile terminal 10 through the direct communication unit 56 (S12: Yes). Next, the control program 65 changes the state of the door of the doorway 111 from the locked state to the unlocked state (S15). As a result, the user who possesses the mobile terminal 10 can open the door of the doorway 111 and go out of the building 110. Then, the control program 65 disconnects the NFC link established with the mobile terminal 10 (S16).

Further, although not shown, the control program 65 of the NFC reader 50B may release the storage area generated in the storage device 73 and accessible to the mobile terminal 10. Specifically, the control program 65 may delete the data stored in the storage area assigned to the terminal ID “term01” included in the response signal and the access setting set in the storage area.

Further, as shown in FIG. 5, the control program 35 of the mobile terminal 10 executes the processes of steps S28 and S30 in response to the time-out of the BT beacon monitoring timer (S21: time-out). The processing of steps S31 to S33 is executed according to the elapse of the first threshold time. The case where the BT beacon monitoring timer times out may be, for example, a case where the user who possesses the mobile terminal 10 goes out of the building 110 without holding the mobile terminal 10 over the NFC reader 50B. Time-out of the BT beacon monitoring timer is another example of a trigger.

Further, when the user turns off the power of the mobile terminal 10 in the building 110, the processes of steps S31 to S33 cannot be executed, so that the mobile terminal 10 storing the communication information may be taken out of the building 110. be. Therefore, the control program 35 of the mobile terminal 10 executes the initial process shown in FIG. 6 in response to the power of the mobile terminal 10 being turned on.

First, the control program 35 of the mobile terminal 10 determines whether or not communication information is stored in the data storage area 32B shown in FIG. 3A (S41). Step S41 is another example of the determination process. Then, the control program 35 ends the initial processing in response to the determination that the communication information is not stored (S41: No).

On the other hand, the control program 35 of the mobile terminal 10 stores the start timing when the power of the mobile terminal 10 is turned on and the data storage area 32B in response to the determination that the communication information is stored (S41: Yes). It is determined whether or not the elapsed time between the reception timing and the reception timing indicated by the timing information has reached the second threshold time (S42). The second threshold time is set to be several hours to several days, which is longer than the first threshold time. Step S42 is another example of the determination process.

Next, the control program 35 of the mobile terminal 10 determines that the elapsed time between the reception timing and the activation timing has reached the second threshold time (S42: Yes), and FIG. 3 (A) shows. The communication information and the timing information are deleted from the data storage area 32B shown in (S43). Further, the control program 35 cancels the setting of the SSID for the Wi-Fi communication unit 25 in response to the SSID included in the deleted communication information being stored in the Wi-Fi communication unit 25. The fact that the elapsed time between the reception timing and the activation timing reaches the second threshold time is an example of the trigger.

On the other hand, in response to the determination that the elapsed time between the reception timing and the activation timing has not reached the second threshold time (S42: No), the control program 35 of the mobile terminal 10 causes the BT beacon transmission device 72 to perform. It is determined whether or not the transmitted BT beacon can be directly received through the communication unit 26 (S44). Then, the control program 35 executes the process of step S43 according to the fact that the BT beacon cannot be received even after a predetermined time has elapsed from the power-on (S44: No). The process of step S44 is another example of the determination process. The fact that the BT beacon cannot be received even after a predetermined time has elapsed is an example of a trigger.

On the other hand, the control program 35 of the mobile terminal 10 sets the SSID stored in the data storage area 32B in the Wi-Fi communication unit 25 in response to receiving the BT beacon through the direct communication unit 26 (S44: Yes). (S45). Further, the control program 35 sets the BT beacon monitoring timer (S46). The processes of steps S45 and S46 are common to the processes of steps S27 and S28. As a result, even if the power of the mobile terminal 10 is turned off when the mobile terminal 10 is in the building 110, the mobile terminal 10 is carried before the elapsed time between the reception timing and the activation timing reaches the second threshold time. When the terminal 10 is restarted, the mobile terminal 10 receives the BT beacon transmitted by the BT beacon transmitting device 72. That is, the mobile terminal 10 can be reconnected to the access point 70 and communicate with the multifunction device 71 and the storage device 73.

[Action and effect of this embodiment]
According to the above embodiment, the access from the mobile terminal 10 to the multifunction device 71 is permitted in response to the reception of the first radio signal including the SSID from the NFC reader 50A, and the trigger caused by the operation of the direct communication unit 26. Access to the multifunction device 71 from the mobile terminal 10 is restricted according to the occurrence of the above. Since these processes are realized by the program installed in the mobile terminal 10, it is not necessary to customize the multifunction device 71 for the processes.

The trigger caused by the operation of the direct communication unit 26 is, for example, that the direct communication unit 26 has received the second radio signal (S24: second transmission device), and the time during which the direct communication unit 26 cannot receive the BT beacon. Has reached the first threshold time (S21: timeout), and the power of the mobile terminal 10 has been turned on after the second threshold time has elapsed since the direct communication unit 26 received the first radio signal (S42: Yes). This includes the fact that the direct communication unit 26 cannot receive the BT beacon within a predetermined time after the power of the mobile terminal 10 is turned on (S44: No). That is, the direct communication unit 26 is not limited to an active operation at the time when the trigger is generated.

Further, according to the above embodiment, since the communication information is automatically deleted without holding the mobile terminal 10 over the NFC reader 50B, it is possible to prevent the communication information from being taken out illegally. As a result, the authority to connect to the communication network can be temporarily given to the mobile terminal 10 to improve the convenience of the guest user and suppress the deterioration of the security of the communication network.

Further, according to the above embodiment, since the mobile terminal 10 can access only the device associated with the BT beacon ID of the received BT beacon, it is possible to limit the devices to be used by the guest user. That is, it is possible to both improve the convenience of the guest user and suppress the deterioration of the security of the communication network.

Further, according to the above embodiment, it is possible to manage the entrance and exit to the building 110 and manage the connection of the mobile terminal 10 to the communication network only by holding the mobile terminal 10 over the NFC reader 50. However, management of entrance and exit to the building 110 is not essential and can be omitted. Further, instead of entering and exiting the building 110, entry and exit to each of the rooms 113 and 114 may be executed.

Further, in the mobile terminal 10 and the NFC reader 50 of the embodiment, the control unit of the present invention is executed by executing various programs stored in the program storage areas 32A and 62A of the storage units 32 and 62 by the CPUs 31 and 61. An example in which each process to be performed is realized has been described. However, the configuration of the control unit is not limited to this, and a part or all of the control unit may be realized by hardware such as an integrated circuit (also referred to as an IC (abbreviation of Integrated Circuit)).

Further, the present invention can be realized not only as a mobile terminal 10 and an NFC reader 50, but also as a program for causing the mobile terminal 10 and the NFC reader 50 to execute a process. Then, the program may be recorded and provided on a non-transitory recording medium. The non-transitory recording medium may include a storage unit mounted on a server device that can be connected to the mobile terminal 10 and the NFC reader 50 through a communication network, in addition to a CD-ROM, a DVD-ROM, and the like. Then, the program stored in the storage unit of the server device may be distributed as information or a signal indicating the program through a communication network such as the Internet.
