FIG. 1 schematically shows an example of the system 10. The system 10 includes a communication device 100. The system 10 may include a plurality of communication devices 100. The system 10 may include a server 300 that manages a plurality of communication devices 100. The system 10 may include a control device 200 connected to the communication device 100.

The communication device 100 and the control device 200 may be so-called IoT devices. The communication device 100 and the control device 200 may be separate bodies. One control device 200 may be connected to the communication device 100. A plurality of control devices 200 may be connected to the communication device 100. The communication device 100 and the control device 200 may be connected by wire. The communication device 100 and the control device 200 may be wirelessly connected. The communication device 100 and the control device 200 may be integrated.

The communication device 100 can access the network 20. The network 20 may include a mobile communication network. The mobile communication network may conform to a 4G (4th Generation) communication method. The mobile communication network may conform to a 5G (5th Generation) communication method. The mobile communication network may conform to a 3G (3rd Generation) communication method. The mobile communication network may conform to the mobile communication system after the 6G (6th Generation) communication system. The network 20 may include the Internet.

The communication device 100 may access the network 20 via radio base stations such as eNB (eNodeB), gNB (gNodeB), and BS (BaseStation). The communication device 100 may access the network 20 via a Wi-Fi® access point. The communication device 100 may be connected to the network 20 by wire.

The communication device 100 may communicate with the server 300 via the network 20. The communication device 100 and the server 300 may communicate according to an arbitrary communication protocol. The communication device 100 and the server 300 communicate with each other according to, for example, LwM2M (Lightweight Machine to Machine). The communication device 100 may be referred to as an LwM2M client. The server 300 may be referred to as an LwM2M server.

The communication device 100 may communicate with the user terminal 400 of a plurality of users 410 via the network 20. The user terminal 400 is, for example, a PC (Personal Computer). The user terminal 400 may be a smartphone, a tablet terminal, or the like.

The communication device 100 may communicate with the user terminal 400 via the server 300. The communication device 100 may transmit information to the user terminal 400 via the server 300. The communication device 100 may receive information from the user terminal 400 via the server 300.

The user terminal 400 may, for example, transmit a request instruction for making an arbitrary request to the control device 200 to the server 300. The user terminal 400 may have an application for communicating with the control device 200 via the server 300. The user 410 may send a request instruction from the user terminal 400 to the server 300 by using the application.

The server 300 may transmit the request instruction received from the user terminal 400 to the communication device 100 corresponding to the target control device 200. The communication device 100 may transmit a request to the control device 200 in response to the received request instruction. The control device 200 may transmit a response to the communication device 100 after executing processing or the like corresponding to the request. The communication device 100 may send a request response to the server 300 in response to receiving the response from the control device 200. The user terminal 400 may acquire the contents included in the request response by accessing the server 300. By providing communication via the server 300 and the communication device 100 in this way, the user 410 can be made to make various requests to the control device 200.

The control device 200 may be installed at an arbitrary place and may execute an arbitrary process. For example, the control device 200 may be installed on the railroad crossing to monitor the state of the railroad crossing as a whole or a part of the railroad crossing, or to provide information indicating the state of the railroad crossing as a whole or a part to the outside. Further, for example, the control device 200 is installed on the home appliance to monitor the state of the whole or a part of the home appliance, provide information indicating the state of the whole or a part of the home appliance to the outside, or the whole of the home appliance. Alternatively, some functions may be performed. The control device 200 may be a temperature sensor that detects the temperature of an arbitrary place. The control device 200 may be a humidity sensor that detects humidity at an arbitrary location. Not limited to these, the control device 200 may be any sensor or any device.

Since the plurality of users 410 cannot normally grasp the instruction status to the control device 200 by the other user 410, the plurality of user terminals 400 transmit the request instruction to one control device 200 at the same timing. Can occur. That is, the communication device 100 can receive a plurality of request instructions in a short period of time. In this case, an unexpected processing load may occur on the communication device 100 and the control device 200. Therefore, if no care is taken, it becomes necessary for the communication device 100 and the control device 200 to have high processing capacity in order to be able to cope with such an unexpected situation, and the communication device 100 and the control device 200 need to have high processing capacity. Cost will increase.

The number of IoT devices will continue to increase in the future, and there may be a huge number. Therefore, it is desirable that the cost of each IoT device is low. The system 10 according to the present embodiment may provide a function of preventing the communication device 100 from simultaneously processing a plurality of request contents included in the request instruction. For example, the system 10 may provide a function that reduces the possibility that the communication device 100 receives a plurality of request instructions in a short period of time.

FIG. 2 schematically shows an example of the processing flow in the system 10. In FIG. 2, a process flow when a user 412, a user 414, and a user 416 are trying to make a request to the control device 200 will be described as an example.

Here, it is assumed that the user ID of the user 412 is "00A", the user ID of the user 414 is "00B", and the user ID of the user 416 is "00C". The user ID may be any information as long as the user 410 can be identified. For example, a user ID is assigned to each user in the system 10. Further, for example, the user ID may be information that can identify the user terminal 400 used by the user 410. As a specific example, the user ID may be the MAC address of the user terminal 400.

Any data model may be used for the communication device 100 and the server 300, but here, a case where an object model of LwM2M is adopted will be described as an example. In the object model, the ID information that can identify the resource can be expressed in the format of "object ID / instance ID / resource ID". The object ID is a unique ID indicating an object. The instance ID is an identifier when a plurality of the same resources exist in one object. The resource ID is a unique ID indicating the resource.

In the example shown in FIG. 2, the communication device 100 and the server 300 use the first ID information (may be described as X) and the second ID information (may be described as Y). Process the request from the user terminal 400. Here, the so-called "Object 19" in the object model is used as the first ID information and the second ID information. For example, the first ID information may be "19/0/0" and the second ID information may be "19/1/0". "Object 19" is defined as an object that handles application service data related to the LwM2M server, and data can be stored in a free format (Opakue type). Therefore, by using "Object 19", an existing object model can be used. It is possible to easily realize the management of the request from the user terminal 400 while making the framework of the above available. In this example, the initial state values of X and Y in the communication device 100 and the server 300 are FREE.

In step 102 (the step may be abbreviated as S) 102, the user terminal 400 of the user 412 transmits a request for acquiring the value of X to the server 300 in order to confirm the reservation. The user terminal 400 may transmit an acquisition request, for example, by using a Resource GET command. In S104, the server 300 transmits FREE, which is the value of X, to the user terminal 400 of the user 412. This confirms that the user terminal 400 of the user 412 can make a reservation.

In S106, the user terminal 400 of the user 412 transmits a write request of "00A", which is the user ID of the user 412, to the communication device 100 in order to give a reservation instruction. The user terminal 400 may send a write request, for example, by using the Resource PUT write command. The user terminal 400 may transmit a write request to the communication device 100 via the server 300. The user terminal 400 may send a write request to the communication device 100 without going through the server 300. The communication device 100 writes "00A" in the value of X according to the write request.

In S108, the communication device 100 notifies the server 300 that "00A" has been written in X. The server 300 writes "00A" to X in response to receiving the notification. This completes the reservation.

In S110, the user terminal 400 of the user 412 transmits a request for acquiring the value of X to the server 300 in order to confirm that the reservation has been completed. In S112, the server 300 transmits "00A", which is the value of X, to the user terminal 400 of the user 412. As a result, the user terminal 400 of the user 412 confirms that the reservation has been completed.

In S114, the user terminal 400 of the user 414 transmits a request for acquiring the value of X to the server 300 in order to confirm the reservation. In S116, the server 300 transmits "00A", which is the value of X, to the user terminal 400 of the user 414. This confirms that the user terminal 400 of the user 414 has already been reserved and cannot be reserved. The user terminal 400 of the user 414 may register the reservation process in order to retry the reservation confirmation after the predetermined waiting time has elapsed. The user terminal 400 of the user 414 may determine the waiting time, for example, by using a random number.

In S118, the user terminal 400 of the user 416 transmits a request for acquiring the value of X to the server 300 in order to confirm the reservation. In S120, the server 300 transmits "00A", which is the value of X, to the user terminal 400 of the user 416. This confirms that the user terminal 400 of the user 416 has already been reserved and cannot be reserved. The user terminal 400 of the user 416 may register the reservation process in order to retry the reservation confirmation after the predetermined waiting time has elapsed. The user terminal 400 of the user 416 may determine the waiting time, for example, by using a random number.

In S122, the user terminal 400 of the user 412 transmits a request for acquiring the value of X to the server 300 in order to confirm again that the reservation has been completed. In S124, the server 300 transmits "00A", which is the value of X, to the user terminal 400 of the user 412. As a result, the user terminal 400 of the user 412 reconfirms that the reservation has been completed.

In S126, the user terminal 400 of the user 412 transmits a request for writing a request instruction to Y to the communication device 100 in response to the confirmation twice that the reservation is completed. The user terminal 400 may transmit a write request to the communication device 100 via the server 300. The user terminal 400 may send a write request to the communication device 100 without going through the server 300. The communication device 100 writes a request instruction to the value of Y according to the write request. Here, the case of confirming that the reservation has been completed twice will be described as an example, but the present invention is not limited to this. The number of confirmations may be once, or may be three or more.

In S128, the communication device 100 transmits a request to the control device 200 based on the request instruction. The control device 200 executes a process corresponding to the request from the communication device 100.

In S130, the control device 200 transmits a response to the communication device 100 in response to the completion of the process. In S132, the communication device 100 transmits the request response to the server 300 in response to receiving the response from the control device 200. The communication device 100 writes FREE in X in response to transmitting the request response.

In S134, the communication device 100 notifies the server 300 that FREE has been written in X. The server 300 writes FREE to X in response to the notification.

In S136, the user terminal 400 of the user 412 transmits an acquisition instruction to the server 300 in order to acquire the content of the request response. In S138, the server 300 transmits an acquisition response including the content of the request response to the user terminal 400 of the user 412 according to the acquisition instruction.

In S140, the user terminal 400 of the user 414 transmits a request for acquiring the value of X to the server 300 in response to the elapse of a predetermined waiting time. In S142, the server 300 transmits FREE, which is the value of X, to the user terminal 400 of the user 414. This will then allow the user 414 to make a request to the control device 200.

By executing the above processing, the system 10 can prevent the simultaneous use of the control device 200 by the plurality of users 410. For example, when the user terminal 400 of the user 412, the user 414, and the user 416 sends a request for acquiring the value of X to the server 300 almost at the same time in order to confirm the reservation, all three recognize it as FREE. Become. As a result, the user terminal 400 of the user 412, the user 414, and the user 416 transmits the write request of the user ID to the communication device 100. However, according to the communication device 100 according to the present embodiment, the user ID is written to X according to, for example, the write request that first reaches the communication device 100 among the three write requests. For example, assuming that "00C" is written, only the user terminal 400 of the user 416 will proceed to the subsequent processing, and the user terminal 400 of the user 412 and the user 414 has elapsed a predetermined waiting time. After that, the reservation confirmation will be executed again. As a result, the control device 200 can sequentially execute the processes corresponding to the requests of the user 412, the user 414, and the user 416. As a result, the processing capacity of the communication device 100 and the control device 200 may be provided with a processing capacity capable of responding to one request, and the cost of the communication device 100 and the control device 200 can be reduced.
