If so, information indicating an abnormality is added to the image transmitted to the information storage server 34.

By the way, in the present embodiment, the wireless communication network 26 existing on the communication path between the terminal device 12 and the information storage server 34 uses a line in advance with the communication carrier that provides the wireless communication network 26. It is only available to subscribers who have signed a contract. Therefore, the profile storage unit 18 has a communication profile for the terminal device 12 to perform wireless communication using the wireless communication network 26, and a terminal identification ID (for example, eUICC-) for identifying each of the plurality of terminal devices 12. ID) and are stored in advance. The terminal identification IDs stored in the profile storage unit 18 of the individual terminal devices 12 are different from each other.

In the present embodiment, an embodiment in which eSIM is applied as an example of the profile storage unit 18 will be described. However, when only one communication profile is stored in the profile storage unit 18 as shown in FIG. 1, the SIM card is used as the profile storage unit 18. Etc. can also be applied.

Wireless communication using the wireless communication network 26 is performed based on the above. Therefore, only one line is required for the usage contract with the communication carrier that provides the wireless communication network 26.

The first communication unit 20 performs wireless communication using the wireless communication network 26 based on the communication profile stored in the profile storage unit 18. An example of wireless communication performed by the first communication unit 20 is high-speed communication such as LTE. Further, the second communication unit 22 performs wireless communication with another terminal device 12 included in the same communication control system 14A. An example of wireless communication performed by the second communication unit 22 is low-speed multi-hop communication.

The communication control unit 24 uses the wireless communication network 26 among a plurality of terminal devices 12 included in the same communication control system 14A by wireless communication with another terminal device 12 by the second communication unit 22. Determines whether the communication-permitted terminal for which wireless communication is permitted is the own device. Then, the communication control unit 24 permits wireless communication by the first communication unit 20 in the first period when the communication permission terminal determines that the device is its own device, and wireless communication by the first communication unit 20 in the second period other than the first period. To stop.

The wireless communication network 26 is provided with a management device 28, which is also called a Subscription Manager (SM), and the management device 28 includes a management information storage unit 30 for storing management information. As shown in FIG. 3, as an example, the management information stored in the management information storage unit 30 includes a communication profile and a terminal device for each subscriber of the wireless communication network 26 that has concluded a line usage contract with a communication carrier. The terminal identification ID (eUICC-ID) of the above is stored in association with each other. The communication profile stored in the management information is a communication profile used by each subscriber, and the terminal identification ID is a terminal identification ID (eUICC-ID) of the terminal device used by each subscriber. The communication profile (“communication profile A” shown in FIG. 1) stored in the profile storage unit 18 of each terminal device 12 of the communication control system 14A is a predetermined one terminal device 12 of the communication control system 14A. It is stored in association with the terminal identification ID of.

The management device 28 has a terminal identification ID (eUICC-ID) of the terminal device that performs wireless communication and a communication profile used by the terminal device that performs wireless communication each time wireless communication using the wireless communication network 26 is started. , Is stored in the management information storage unit 30 as management information. Then, when the set of the terminal identification ID (eUICC-ID) and the communication profile is stored as management information, wireless communication is permitted, and when the set is not stored as management information, the wireless communication is blocked. conduct.

The terminal device 12 can be realized by, for example, the computer 40 shown in FIG. The computer 40 includes a CPU 42, a memory 44 as a temporary storage area, a non-volatile storage unit 46, an input unit 48 such as a keyboard, a display unit 50 such as a display, an eSIM 52, a sensor 54, a camera 56, and a wireless communication unit 58. The CPU 42, the memory 44, the storage unit 46, the input unit 48, the display unit 50, the eSIM 52, the sensor 54, the camera 56, and the wireless communication unit 58 are connected to each other via the bus 60. The eSIM 52 is an example of the profile storage unit shown in FIG. 1, and the wireless communication unit 58 is an example of the first communication unit 20 and the second communication unit 22.

The storage unit 46 is realized by an HDD (Hard Disk Drive), an SSD (Solid State Drive), a flash memory, or the like. The storage unit 46 stores a communication control program 62 for making the computer 40 function as the terminal device 12, and is provided with a communication permission terminal information storage area 68 and a transmission information storage area 70. The CPU 42 reads the communication control program 62 from the storage unit 46, expands the communication control program 62 into the memory 44, and sequentially executes the processes included in the communication control program 62.

The communication control program 62 includes an information acquisition process 64 and a communication control process 66. By executing the information acquisition process 64, the CPU 42 operates as the information acquisition unit 16 shown in FIG. 1, acquires the information detected by the sensor 54 and the image captured by the camera 56, and stores the information in the transmission information storage area 70. Perform the process of memorizing. Further, the CPU 42 operates as the communication control unit 24 shown in FIG. 1 by executing the communication control process 66. As a result, the computer 40 that has executed the communication control program 62 functions as the terminal device 12.

Further, in the communication permitted terminal information storage area 68 of the storage unit 46, the terminal identification ID (terminal identification ID) of any one of the plurality of terminal devices 12 included in the communication control system 14A, which is set in the communication permitted terminal. eUICC-ID) is stored as communication permitted terminal information. The initial value of the communication permitted terminal information is a predetermined terminal device stored in the management information storage unit 30 in association with the communication profile (communication profile A) stored in the profile storage unit 18 of each terminal device 12. 12 terminal identification IDs.

Next, as the operation of the first embodiment, first, with reference to FIG. 5, the communication control process performed by the individual terminal devices 12 included in the communication control system 14A will be described. In step 100 of the communication control process, the communication control unit 24 of the terminal device 12 refers to the communication permission terminal information stored in the communication permission terminal information storage area 68 of the storage unit 46. Then, in step 102, the communication control unit 24 determines whether or not the referenced communication permission terminal information matches the terminal identification ID (eUICC-ID) of its own device stored in the profile storage unit 18. Determines whether the own device is a communication-permitted terminal.

If the determination in step 102 is denied, the process proceeds to step 104, and in step 104, whether the communication control unit 24 stores the information to be transmitted to the information storage server 34 in the transmission information storage area 70 of the storage unit 46. Judge whether or not. If the determination in step 104 is affirmed, the process proceeds to step 106, and in step 106, the communication control unit 24 sends a transmission request for information stored in the transmission information storage area 70 to the current communication permitted terminal. Determine if it has not been sent.

If the determination in step 106 is affirmed, the process proceeds to step 108. In step 108, the communication control unit 24 transmits a transmission request including the terminal identification ID (eUICC-ID) of the own device, the type of information stored in the transmission information storage area 70, and the amount of data to the communication permitted terminal. The process proceeds to step 110. As a result, as shown by the notation "transmission request" in FIG. 8, each terminal device 12 other than the communication permitted terminal shown by the alternate long and short dash line in FIG. 8 has information to be transmitted to the information storage server 34. In that case, each transmission request is transmitted to the communication permitted terminal. If the determination in step 104 or step 106 is denied, step 108 is skipped and the process proceeds to step 110.

In step 110, the communication control unit 24 determines whether or not the next communication permission terminal (hereinafter referred to as “next communication permission terminal”) has been notified from the current communication permission terminal. If the determination in step 110 is denied, the process returns to step 100, and steps 100 to 110 are repeated.

When the next communication permitted terminal is notified from the current communication permitted terminal, the determination in step 110 is affirmed and the process proceeds to step 112 (see also "Notification of next communication permitted terminal" shown in FIG. 8). In step 112, the (eUICC-ID) communication control unit 24 transfers the terminal identification ID of the next communication permitted terminal notified from the current communication permitted terminal to the communication permitted terminal information storage area 68 of the storage unit 46. Remember as. In step 114, the communication control unit 24 determines whether or not the terminal identification ID (eUICC-ID) of the next communication permission terminal notified from the current communication permission terminal matches the terminal identification ID (eUICC-ID) of its own device. Based on the above, it is determined whether or not the own device is the next communication permitted terminal.

If the determination in step 114 is denied, the process returns to step 100, and the processes after step 100 are repeated. Here, when the information to be transmitted to the information storage server 34 is stored in the transmission information storage area 70, the determinations in steps 104 and 106 described above are affirmed, so that the new communication permission terminal can be reached. The transmission request is sent.

If the own device is the next communication permitted terminal, the determination in step 114 is affirmed and the process proceeds to step 116. In step 116, the communication control unit 24 determines whether or not the current communication permission terminal has notified the completion of switching of the communication permission terminal. If the determination in step 116 is denied, step 116 is repeated until the determination is affirmed.

When the current communication permitted terminal notifies the completion of switching of the communication permitted terminal (see also "notification of switching completion" shown in FIG. 8), the determination in step 116 is affirmed and the process proceeds to step 118. In step 118, the communication control unit 24 activates the communication profile of the own device stored in the profile storage unit 18, and returns to step 100. In this case, if the determination of the next step 102 is affirmed, the process proceeds to step 122.

In step 122, the communication control unit 24 reads a predetermined amount of information stored in the transmission information storage area 70 from the storage unit 46, and stores the read information by the first communication unit 20 via the wireless communication network 26. It sends to the server 34 (see also "data communication" shown in FIG. 8). At this time, the communication profile stored in the profile storage unit 18 (“communication profile A” shown in FIG. 1) is used for wireless communication between the first communication unit 20 and the wireless communication network 26.

Details will be described later, but at this time, the communication profile A and the terminal identification ID of the own device are registered in association with the management information stored in the management information storage unit 30 of the management device 28. Wireless communication with the wireless communication network 26 by 1 communication unit 20 is permitted. Therefore, the information transmitted by the first communication unit 20 in step 122 is received by the information storage server 34 and stored and stored in a storage unit (not shown) of the information storage server 34. The communication control unit 24 deletes the information that has been transmitted to the information storage server 34 in step 122 from the transmission information storage area 70.

In the next step 124, the communication control unit 24 determines whether or not all the information stored in the transmission information storage area 70 has been transmitted to the information storage server 34. If the determination in step 124 is denied, the process returns to step 122, and steps 122 and 124 are repeated until the determination in step 124 is affirmed. When all the information stored in the transmission information storage area 70 is transmitted to the information storage server 34, the determination in step 124 is affirmed and the process proceeds to step 126.

In step 126, the communication control unit 24 performs a communication permission terminal determination process. Hereinafter, the communication permission terminal determination process will be described with reference to FIG.

In step 150 of the communication permission terminal determination process, the communication control unit 24 determines whether or not the own device, that is, the communication permission terminal has received the transmission request from the other terminal device 12. If the determination in step 150 is denied, the process proceeds to step 152, and in step 152, the communication control unit 24 waits for a predetermined time and then returns to step 150. Therefore, steps 150 and 152 are repeated while the transmission request is not received from the other terminal device 12. When the transmission request is received from the other terminal device 12, the determination in step 150 is affirmed and the process proceeds to step 154.

In step 154, the communication control unit 24 determines whether or not the own device, that is, the communication permission terminal has received the transmission request from the plurality of terminal devices 12. If the determination in step 154 is denied, the process proceeds to step 156, and in step 156, the communication control unit 24 determines the only terminal device 12 that has transmitted the transmission request as the next communication permitted terminal, and the communication permitted terminal determination process. To finish.

Further, when the own device, that is, the communication permitted terminal receives the transmission request from the plurality of terminal devices 12, the determination in step 154 is affirmed and the process proceeds to step 158. In step 158, the communication control unit 24 confirms the type and amount of data of the transmission information included in the transmission request received from each of the plurality of terminal devices 12. Then, in the next step 160, the communication control unit 24 determines whether or not there is a transmission request including information indicating an abnormality among the transmission requests received from the plurality of terminal devices 12.

If the determination in step 160 is affirmed, the process proceeds to step 162, and in step 162, if there is only one terminal device 12 that has transmitted a transmission request including information indicating an abnormality, the communication control unit 24 is the terminal device. 12 is determined as the next communication permitted terminal. Further, when there are a plurality of terminal devices 12 that have transmitted transmission requests including information indicating an abnormality, the communication control unit 24 transmits among the plurality of terminal devices 12 that have transmitted transmission requests including information indicating an abnormality. The terminal device 12 having the smallest amount of data of the target information is determined as the next communication permitted terminal. Then, when the process of step 162 is performed, the communication permission terminal determination process is terminated.

When the information storage server 34 receives information indicating an abnormality from the terminal device 12, the information storage server 34 performs processing such as notifying the administrator, for example. As described above, by preferentially determining the terminal device 12 whose transmission target is information indicating an abnormality as the next communication permitted terminal, processing such as notifying the administrator by the information storage server 34 is performed at an early stage. Therefore, it becomes possible for the administrator to deal with the abnormalities that have occurred at an early stage.

If the terminal device 12 that has transmitted the transmission request including the information indicating the abnormality does not exist, the determination in step 160 is denied and the process proceeds to step 164. In step 164, the communication control unit 24 determines whether or not there is a transmission request requesting transmission of image data among the transmission requests received from the plurality of terminal devices 12.

If the determination in step 164 is affirmed, the process proceeds to step 166, and in step 166, the communication control unit 24 uses the terminal device 12 if the number of the terminal devices 12 requesting the transmission of image data is one. Decide on the next communication permitted terminal. Further, when the communication control unit 24 has a plurality of terminal devices 12 requesting the transmission of image data, the communication control unit 24 has the image data to be transmitted among the plurality of terminal devices 12 requesting the transmission of the image data. The terminal device 12 having the smallest amount of data is determined as the next communication permitted terminal. Then, when the process of step 166 is performed, the communication permission terminal determination process is terminated.

If the terminal device 12 requesting the transmission of image data does not exist, the determination in step 164 is denied and the process proceeds to step 168. In step 168, the communication control unit 24 determines the terminal device 12 having the smallest data amount of the information to be transmitted among the plurality of terminal devices 12 that have transmitted the transmission request as the next communication permitted terminal, and determines the communication permitted terminal. End the process.

When the communication permission terminal determination process is completed, the process proceeds to step 128 of the communication control process shown in FIG. In step 128, the communication control unit 24 notifies all the terminal devices 12 other than the own device of the terminal identification ID (eUICC-ID) of the next communication permission terminal determined in the above-mentioned communication permission terminal determination process (FIG. 8). See also "Notification of next communication permitted terminal" shown in.

In the next step 130, the communication control unit 24 requests the management device 28 to rewrite the management information stored in the management information storage unit 30. Specifically, among the management information, the terminal identification ID (eUICC-ID) associated with the communication profile currently used is written from the terminal identification ID of the own device to the terminal identification ID of the next communication permitted terminal. Request to change. It should be noted that this request also includes the terminal identification ID (eUICC-ID) of the next communication permitted terminal. FIG. 8 shows the above request as “eUICC-ID rewriting request”. In the next step 132, the communication control unit 24 determines whether or not the management device 28 has notified the completion of the rewriting. If the determination in step 132 is denied, the process returns to step 130, and steps 130 and 132 are repeated until the determination in step 132 is affirmed.

During this time, the management device 28, which is requested to rewrite the management information from the terminal device 12 (current communication permitted terminal), performs the management information rewriting process shown in FIG. 7. In step 180 of the management information rewriting process, the management device 28 recognizes the communication profile currently used by the terminal device 12 (current communication permitted terminal) that is the rewriting request source. In the next step 182, the management device 28 searches for the management information stored in the management information storage unit 30 by using the communication profile recognized in the step 180 as a key.

In step 184, the management device 28 requests the rewriting of the terminal identification ID associated with the communication profile extracted by the search in step 182 on the management information from the terminal identification ID of the terminal device 12 that is the rewriting request source. Rewrite to the terminal identification ID of the next communication permitted terminal included in. Then, in step 186, the management device 28 notifies the terminal device 12 (current communication permitted terminal) of the rewriting request source of the completion of rewriting of the management information (see also "rewriting completion notification" shown in FIG. 8). , End the management information rewriting process.

When the terminal device 12 (current communication permitted terminal) that has requested the rewriting of the management information is notified by the management device 28 that the rewriting of the management information is completed, the determination in step 132 of FIG. 5 is affirmed and the process proceeds to step 134. Transition. In step 134, the communication control unit 24 invalidates the communication profile of the own device stored in the profile storage unit 18.

Then, in step 136, the communication control unit 24 notifies the next communication permission terminal of the completion of switching, and returns to step 100. As a result, in the terminal device 12 (next communication permission terminal) notified of the completion of switching, the switching of the communication permission terminal in the communication control system 14A is completed by performing the process of step 118 described above. Then, information is transmitted from the terminal device 12 which has become a communication permission terminal to the information storage server 34.

[Second Embodiment]
Next, a second embodiment of the disclosed technique will be described. Since the second embodiment has the same configuration as the first embodiment, the same reference numerals are given to the respective parts to omit the description of the configuration. Hereinafter, as the operation of the second embodiment, the first embodiment is used. Explain the different parts.

In the first embodiment, the communication permitted terminal determines the next communication permitted terminal, but in this embodiment, each terminal device 12 transmits a transmission request to a new communication permitted terminal each time the communication permitted terminal is switched. There is a need. In the second embodiment, the terminal device 12 that determines the next communication permitted terminal is fixed to a specific terminal device 12 (hereinafter referred to as a specific terminal) in the communication control system 14A, so that the traffic in the communication control system 14A is used. To reduce.

In the second embodiment, each terminal device 12 of the communication control system 14A performs the communication control process shown in FIG. In the communication control process according to the second embodiment, as compared with the first embodiment (FIG. 5), the own device is not a communication permitted terminal (step 102 is denied), and information is stored in the transmission information storage area 70. If there is (step 104 is affirmative), the difference is that the process proceeds to step 107. In step 107, the communication control unit 24 determines whether or not the transmission request for the information stored in the transmission information storage area 70 has not been transmitted to the specific terminal.

If the determination in step 107 is affirmed, the process proceeds to step 109. In step 109, the communication control unit 24 transmits a transmission request including the terminal identification ID (eUICC-ID) of the own device, the type of information stored in the transmission information storage area 70, and the amount of data to the specific terminal. Move to 110. As a result, as shown in FIG. 11 as "transmission request", the terminal device 12 other than the specific terminal shown by the broken line in FIG. 11 is a specific terminal when there is information to be transmitted to the information storage server 34. Send a send request to.

When the information is not stored in the transmission information storage area 70 (step 104 is negative), or when the transmission request for the information stored in the transmission information storage area 70 has already been transmitted to the specific terminal (step 107 is negative). ) Skips step 109 and proceeds to step 110. As a result, terminals other than the specific terminal do not need to transmit the transmission request every time the communication permitted terminal is switched, and each time new information is stored in the transmission information storage area 70, the transmission request is transmitted to the specific terminal. You only have to do it.

Further, in the communication control process according to the second embodiment, as compared with the first embodiment (FIG. 5), the own device is a communication permitted terminal (step 102 is affirmative), and the information transmission to the information storage server 34 is completed. If this is the case (step 124 is affirmative), the process proceeds to step 190. In step 190, the communication control unit 24 inquires about the next communication permitted terminal to the specific terminal (see also "inquiry about the next communication permitted terminal" shown in FIG. 11). In the next step 192, it is determined whether or not the next communication permission terminal is notified from the specific terminal. If the determination in step 192 is denied, step 192 is repeated until the determination is affirmed.

On the other hand, the specific terminal that has received the inquiry of the next communication permitted terminal from the communication permitted terminal performs the communication permitted terminal determination process shown in FIG. In step 230 of the communication permission terminal determination process, the communication control unit 24 of the specific terminal determines whether or not the terminal device 12 in the transmission request including its own device exists in each terminal device 12 of the communication control system 14A. Is determined.

Here, whether or not the own device (specific terminal) is requesting transmission can be determined based on whether or not information is stored in the transmission information storage area 70 of the own device. Further, whether or not the individual terminal device 12 other than the own device (specific terminal) is requesting transmission is determined by the individual terminal device in the period after the individual terminal device 12 is determined to be the communication permitted terminal. It can be determined based on whether or not it has been received.

If the determination in step 230 is denied, the process proceeds to step 232, and in step 232, the communication control unit 24 of the specific terminal waits for a predetermined time and then returns to step 230.

The terminal device 12 having the smallest amount of information data is determined as the next communication permitted terminal. Then, when the process of step 242 is performed, the process proceeds to step 250.

Further, if the terminal device 12 whose transmission target is information indicating an abnormality does not exist in the terminal device 12 during the transmission request, the determination in step 240 is denied and the process proceeds to step 244. In step 244, the communication control unit 24 of the specific terminal determines whether or not the terminal device 12 whose image data is to be transmitted is included in the plurality of terminal devices 12 in the transmission request.

See also "Notification of next communication permitted terminal" from terminal A to terminal B shown in (1).

In the second embodiment, the processes other than the above-described processes are the same as those in the first embodiment, and thus the description thereof will be omitted.

[Third Embodiment]
Next, a third embodiment of the disclosed technology will be described. The same parts as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted, and only the parts different from those in the first embodiment will be described.

FIG. 12 shows the management / monitoring system 10B according to the third embodiment. The management / monitoring system 10B includes a communication control system 14B. In the communication control system 14B, as compared with the communication control system 14A according to the first embodiment, the profile storage unit 18 of each terminal device 12 has a plurality of communication profiles (“communication profile A” and “communication profile B” in FIG. 12). ") Is different in that it remembers. In the third embodiment, as an example of a plurality of communication profiles, a mode in which different communication profiles for using the same wireless communication network 26 are applied will be described. However, the present invention is not limited to this, and the plurality of communication profiles may be communication profiles for using the wireless communication network 26 provided by different communication carriers.

In the third embodiment, each terminal device 12 of the communication control system 14B performs the communication control process shown in FIG. In the communication control process according to the third embodiment, as compared with the first embodiment (FIG. 5), the own device is a communication permission terminal (step 102 is affirmative), and a predetermined amount stored in the transmission information storage area 70. When the information of is transmitted to the information storage server 34 (step 122), the process proceeds to step 200. In step 200, the communication control unit 24 of the communication permission terminal determines whether or not a communication failure has occurred in transmitting information to the information storage server 34.

If the determination in step 200 is denied, the process proceeds to step 124, and in step 124, the communication control unit 24 of the communication permission terminal stores the information stored in the transmission information storage area 70 as in the first embodiment. It is determined whether or not all the information has been transmitted to the information storage server 34. If the determination in step 124 is denied, the process returns to step 122, and steps 122,200, and 124 are repeated until the determination in step 200 is affirmed or the determination in step 124 is affirmed. When the transmission of information to the information storage server 34 is completed without any communication failure in the middle, the determination in step 124 is affirmed, and the process proceeds to step 126 as in the first embodiment.

On the other hand, if a communication failure occurs in the middle of transmitting information to the information storage server 34, the determination in step 200 is affirmed and the process proceeds to step 202. Perform profile switching processing.

As shown in FIG. 14, in step 210 of the profile switching process, the communication control unit 24 of the communication permission terminal requests the management device 28 to include the terminal identification ID of the own device and the communication profile after switching as information. To send. In the next step 212, the communication control unit 24 of the communication permission terminal determines whether or not the management device 28 has notified that the switching of the communication profile has been completed. If the determination in step 212 is denied, the process returns to step 210, and steps 210 and 212 are repeated until the determination in step 212 is affirmed.

During this time, the management device 28, which is requested by the terminal device 12 (communication permitted terminal) to switch the communication profile, performs the profile switching process shown in FIG. In step 220 of the profile switching process, the management device 28 extracts the terminal identification ID of the communication permitted terminal from the received profile switching request. In the next step 222, the management device 28 searches for the management information stored in the management information storage unit 30 by using the terminal identification ID of the communication permission terminal extracted in step 220 as a key.

In step 224, the management device 28 includes the communication profile associated with the terminal identification ID extracted in the search in step 222 on the management information, and the communication profile after switching included in the profile switching request received from the communication permitted terminal. Rewrite to. Then, in step 226, the management device 28 notifies the communication permission terminal of the completion of the communication profile switching, and ends the profile switching process (FIG. 15).

When the management device 28 notifies the communication permission terminal that the rewriting of the management information is completed, the determination in step 212 of FIG. 14 is affirmed and the communication permission terminal proceeds to step 214. In step 134, the communication control unit 24 of the communication permission terminal invalidates the communication profile that has been used so far among the plurality of communication profiles stored in the profile storage unit 18 of the own device, and after switching. Enable the communication profile. When the process of step 134 is performed, the profile switching process (FIG. 14) is terminated and the process returns to step 122 of FIG. As a result, information transmission to the information storage server 34 is resumed based on the communication profile after switching, so that there is a possibility that the communication failure may be resolved by switching the communication profile, and information storage from the terminal device 12 occurs. The delay in transmitting information to the server 34 is suppressed.

Further, in the third embodiment, when the communication permitted terminal is notified to the next communication permitted terminal that the switching of the communication permitted terminal is completed, the communication profile currently in use is also notified (see step 204 in FIG. 13). As a result, the new communication-permitted terminal transmits information to the information storage server 34 based on the notified communication profile in use.

As described above, in each of the above-described embodiments, the first communication unit 20 goes through the wireless communication network 26 based on the communication profile stored in the profile storage unit 18 for using the wireless communication network 26.

Then, the communication control unit 24 permits the communication by the first communication unit 20 via the wireless communication network 26 in the first period determined by the communication permission terminal to be the own device, and the own device is not the communication permission terminal. During the second period, the communication by the first communication unit 20 via the wireless communication network 26 is stopped. This eliminates the need to transfer the information transmitted from the individual terminal devices 12 to the information storage server 34 between the terminal devices 12, and suppresses the time required for information transmission from the individual terminal devices 12 to the information storage server 34. can. Further, since the individual terminal devices use the same communication profile in a time-divided manner to transmit information to the information storage server 34, the cost required for information transmission from the individual terminal devices 12 to the information storage server 34 can be suppressed.

Further, in each of the above-described embodiments, the second communication unit 22 wirelessly communicates with another terminal device 12, and the communication control unit 24 communicates through wireless communication with the other terminal device 12 by the second communication unit 22. Determine if the authorized terminal is your device. Wireless communication with other terminal devices 12 is generally slow, but if this wireless communication is used to determine whether or not the communication permitted terminal is its own device, each terminal device 12 goes to the information storage server 34. It is possible to suppress adverse effects on the time required for transmitting information.

Determine the terminal. Then, when the communication of the own device is completed, the determined communication permission terminal is notified to the other terminal device 12. As a result, even if some of the terminal devices in the communication control system including the plurality of terminal devices malfunction, information transmission to the information storage server 34 is performed without affecting the other terminal devices. It can be carried out.

Further, in the second embodiment, when the own device is a specific terminal, the communication control unit 24 sets the wireless communication network 26 every time the communication via the wireless communication network 26 by the current communication permitted terminal is completed. The next communication permitted terminal is determined from the terminal devices 12 requesting communication via the terminal device 12. Then, the communication control unit 24 notifies the other terminal device 12 of the determined next communication permission terminal by the second communication unit 22. This makes it possible to reduce communication between terminal devices in a communication control system including a plurality of terminal devices.

Further, when the own device is a communication permitted terminal in the first and third embodiments, and when the own device is a specific terminal in the second embodiment, the communication control unit 24 goes through the wireless communication network 26. A communication permitted terminal is determined from the terminal devices 12 requesting communication. Further, the communication permission terminal is determined based on at least one of the type, amount of information, and priority of the information to be communicated included in the transmission request. As a result, the time until the communication via the wireless communication network 26 is completed is determined by at least the type, amount, and priority of the information to be communicated, as compared with the case where the communication permitted terminal is randomly determined. It can be controlled according to one.

Further, in each of the above-described embodiments, when the communication control unit 24 completes the communication by the first communication unit 20 via the wireless communication network 26 when the own device is a communication permission terminal, the communication control unit 24 performs the wireless communication network 26. The following request is made to the management device 28 existing on the side. That is, the management device 28 stores the communication profile and the terminal identification ID of the current communication permission terminal in the management information storage unit 30 in association with each other. The first communication unit 20 requests the management device 28 to rewrite the terminal identification ID stored in the management information storage unit 30 to the terminal identification ID of the next communication permission terminal via the wireless communication network 26. do. Then, the communication control unit 24 performs a process of switching the communication permission terminal from its own device to the next communication permission terminal after the management device 28 notifies that the rewriting of the terminal identification ID of the communication permission terminal is completed. As a result, it is possible to switch the communicable terminal to time division without being rejected by the management device 28 existing on the wireless communication network 26 side.

Further, in the third embodiment, a plurality of communication profiles different from each other are stored in the profile storage unit 18. Further, the communication control unit 24 is stored in the profile storage unit 18 by the first communication unit 20 when a communication failure occurs in the communication based on the first communication profile stored in the profile storage unit 18.

As a result, it is possible to reduce the frequency with which communication via the wireless communication network 26 is delayed due to a communication failure or the like.

In the first and third embodiments, the communication permitted terminal is determined, and in the second embodiment, the specific terminal determines the communication permitted terminal, but the present invention is not limited thereto. The communication permission terminal can also be determined by an external device of the communication control system 14, for example, an information storage server 34 or a management device 28. However, in this case, since it is necessary to change the configuration of the external device, it is preferable to use any terminal device 12 in the communication control system 14.

Further, in each of the above embodiments, the mode in which any terminal device 12 in the communication control system 14 determines the communication permitted terminal has been described, but the process of determining the communication permitted terminal can be omitted. For example, the time and order for allocating the individual terminal devices 12 in the communication control system 14 to the communication permitted terminals are determined in advance. Then, each terminal device 12 determines the period during which the own device is a communication permitted terminal based on a predetermined time and order, and wireless communication is performed only during the period when the own device is a communication permitted terminal. Information is transmitted to the information storage server 34 via the network 26. In this embodiment, if each terminal device 12 also calibrates the time of the built-in timer while the own device is a communication permitted terminal, wireless communication between the terminal devices 12 can be omitted. It is possible.
