[Configuration of Communication System S]
FIG. 1 is a diagram illustrating a configuration of a communication system S according to the embodiment. The communication system S includes a plurality of communication devices 1 (illustrating communication devices 1a, 1b, and 1c in FIG. 1), a communication terminal 2, a data management device 3, and a data acquisition device 4 (data acquisition device in FIG. 1). 4a, 4b, 4c). The communication terminal 2 can transmit device data received from a plurality of communication devices 1 to the data management device 3 via the communication network N1 and the relay network N2.

  The communication network N1 is a mobile phone network and includes a plurality of base stations 5 (base stations 5a, 5b, and 5c in FIG. 1). Each of the plurality of base stations 5 is eNodeB in LTE (Long Term Evolution), for example. Each of the plurality of base stations 5 is connected to the plurality of communication terminals 2 by wireless communication lines. The communication terminal 2 can transmit device data received from the communication device 1 to the data management apparatus 3 using a wireless communication line provided from the base station 5.

  The relay network N2 is a network including an EPC (Evolved Packet Core) such as an LTE PGW (Packet Data Network Gateway) or an MME (Mobility Management Entity). A plurality of base stations 5 are connected to the relay network N2. The relay network N2 is connected to the data management device 3 via the Internet, for example.

  The communication device 1 has a sensor, for example, and transmits device data based on the output signal of the sensor to the communication terminal 2. The communication device 1 transmits / receives data to / from the communication terminal 2 via a wireless communication channel suitable for communication at a relatively short distance, such as Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like.

  The communication device 1 is installed in a vending machine, a vehicle, an office, a factory, and the like, and device data including various types of information that can be collected at the installation location is sent to the data management apparatus 3 via the communication terminal 2. Send. When the communication device 1 is installed in, for example, a vending machine, the communication device 1 collects information on temperature, the remaining amount of change, the stock of goods, the presence of surrounding people, and the like, and includes the collected information Data is transmitted to the communication terminal 2.

  The capacity of device data transmitted by the communication device 1 is smaller than the capacity of voice and image data transmitted and received in communication terminals such as smartphones and tablets, and the length of one device data is, for example, 100 bytes or less. . The device data transmitted by the communication device 1 includes a device ID that is identification information assigned to each communication device 1 and data including the collected information.

  The communication terminal 2 receives a plurality of device data from the plurality of communication devices 1. Although details will be described later, the communication terminal 2 temporarily stores the received device data, and sends the stored device data to the communication network N1 at a timing determined based on the state of the communication device 1. The device data is transferred to the data management device 3.

  The data management device 3 is, for example, a server managed by a communication carrier that provides a service using the communication network N1. The data management device 3 provides device data received from the communication terminal 2 to the data acquisition device 4 via the communication network N1 and the relay network N2.

  Specifically, the data management device 3 collects device data transmitted from the plurality of communication devices 1 via the communication terminal 2 and the communication network N1. The data management device 3 accumulates the received device data in a storage medium such as a hard disk and generates the device data itself or based on the device data in response to a request from the data acquisition device 4 (4a, 4b, 4c) Information is transmitted to the data acquisition device 4.

  The data acquisition device 4 is a computer that can access the data management device 3. The data acquisition device 4 is, for example, a PC (Personal Computer) used by a data acquirer who accesses data transmitted from the communication device 1 to the data management device 3. The contents of the device data transmitted by 1 can be browsed.

  Here, when the communication device 1 is installed in the vending machine, the data acquirer is, for example, a management company of the vending machine, a beverage manufacturer that manufactures products of the vending machine, a company that provides marketing information, or the like. . The data acquirer has signed a contract with a communication carrier that manages the data management apparatus 3 for acquiring device data output by a desired application of the desired communication device 1. The data management device 3 obtains an acquirer ID of each data acquirer, a device ID of one or more communication devices 1 selected by each data acquirer, and an application ID of one or more applications selected by each data acquirer. It is associated and remembered.

  FIG. 2 is a diagram schematically illustrating a data flow in the communication system S. One communication device 1 can execute a plurality of applications corresponding to a plurality of types of information. The communication device 1 shown in FIG. 2 is installed in a vending machine and can execute a temperature application 11, a change management application 12, an inventory management application 13, and a monitoring application 14.

  The temperature application 11 can transmit temperature information indicating the internal temperature of the vending machine. The change management application 12 can transmit change information indicating the change balance of the vending machine. The stock management application 13 can transmit stock information indicating the number of stocks of products sold by the vending machine. The monitoring application 14 can transmit person detection information indicating the time when a person within a predetermined distance is detected from the vending machine.

  Information transmitted by each application is allocated to the data acquisition device 4 registered in advance by the data management device 3. In the example shown in FIG. 2, the temperature information output by the temperature application 11 is transmitted to the data acquisition device 4a of the data acquirer who maintains the vending machine. The change information output by the change management application 12 is transmitted to the data acquisition device 4b of the data acquirer who manages the product. The inventory information output by the inventory management application 13 is transmitted to the data acquisition device 4b and the data acquisition device 4c of the data acquirer that provides the marketing information. The person detection information output by the monitoring application 14 is transmitted to the data acquisition device 4c.

  In addition, the place where the communication device 1 is installed is arbitrary, and may be installed in an automobile, for example. When the communication device 1 is installed in an automobile, the communication device 1 includes the remaining amount of gasoline, the remaining amount of battery, travel data (travel distance, average speed, fuel consumption, number of sudden brakes, etc.), position information, vehicle body defect information, etc. Can be transmitted to the data management device 3.

  By the way, when there are many communication terminals 2 accommodated in one base station 5 and there are many communication devices 1 connected to the communication terminals 2, device data output by the many communication devices 1 is transmitted to the communication network N1. Will be. If a large amount of device data is transmitted at the same time, the communication network N1 becomes congested. Therefore, the communication terminal 2 accumulates the device data, and transmits the accumulated device data in a time zone in which the traffic of the communication network N1 is low. Can be considered.

  However, it is not preferable that device data that needs to be transmitted in real time is accumulated in the communication terminal 2 for a long time. For example, when the communication device 1 is installed and the power is turned on, the person who monitors whether or not the installation has succeeded is monitored by the person who monitors whether or not the device data related to the initial setting output from the communication device 1 is transmitted. Have to wait for a long time before being sent.

Therefore, the communication terminal 2 according to the present embodiment controls the priority of transmitting device data according to the state of the communication device 1, so that it is necessary to transmit the device immediately as in the initial setting, for example. It is characterized in that data can be transmitted promptly. For example, when the communication device 1 transmits device data to the communication terminal 2 for the first time after the power is turned on, the communication terminal 2 completes initial setting of the device data transmitted to the communication terminal 2 for the first time after the communication device 1 is installed. After the power failure is restored, the data is transmitted to the communication network N1 with higher priority than the device data transmitted by the communication device 1.
Hereinafter, the configuration of the communication terminal 2 will be described in detail.

[Configuration of communication terminal 2]
Next, the configuration and operation of the communication terminal 2 will be described.
FIG. 3 is a diagram illustrating a configuration of the communication terminal 2. The communication terminal 2 includes a device communication unit 21, a network communication unit 22, a storage unit 23, and a communication control unit 24.

The device communication unit 21 is a wireless communication interface for receiving data transmitted by the communication device 1.
The network communication unit 22 is a wireless communication interface for transmitting data received from the communication device 1 to the communication network N1. The network communication unit 22 can transmit and receive data to and from the base station 5 of the communication network N1, for example, according to the LTE standard.

  The storage unit 23 includes a storage medium such as a ROM (Read Only Memory), a RAM (Random Access Memory), and a hard disk. The storage unit 23 stores a communication program executed by the communication control unit 24. Further, the storage unit 23 stores the device data received from the communication device 1 in association with the device ID of the communication device 1 and the date and time received from the communication device 1 based on the control of the communication control unit 24.

Further, the storage unit 23 stores a reception history in which the device communication unit 21 has received predetermined data transmitted by the communication device 1 in an initial state.
FIG. 4 is a diagram illustrating an example of a reception history database stored in the storage unit 23. In the reception history database, a state flag indicating whether each of the plurality of communication devices 1 with which the communication terminal 2 can communicate is in an initial state and a device ID are associated with each other.

  The storage unit 23 is a flag of 0 indicating the initial state in association with the device ID for identifying the communication device 1 until the device communication unit 21 receives the device data transmitted from the communication device 1 at the time of initial setting. Remember. After the device communication unit 21 receives device data transmitted from the communication device 1 at the time of initial setting, the storage unit 23 stores a flag of 1 indicating a state in which the initial setting is completed in association with the device ID.

  The communication control unit 24 is, for example, a CPU (Central Processing Unit), and executes various operations by executing a communication program stored in the storage unit 23. The communication control unit 24 specifies the state of the communication device 1. The communication control unit 24 stores the device data received via the device communication unit 21 in the storage unit 23, and the device data stored in the storage unit 23 has a priority according to the identified state of the communication device 1. The device data received by the device communication unit is transmitted to the communication network N1.

  For example, the communication control unit 24 determines whether the communication device 1 is in an initial state or a non-initial state based on device data received by the device communication unit 21 from the communication device 1. When the communication control unit 24 determines that the communication device 1 is in the initial state, the communication control unit 24 transmits device data at an earlier timing than when the state specifying unit determines that the communication device 1 is in the non-initial state.

  The communication control unit 24, when the device communication unit 21 receives predetermined data from the communication device 1, when the reception history indicating that the device data transmitted at the initial setting is received is not stored in the storage unit 23 (For example, when the flag is 0), it is determined that the communication device 1 is in the initial state. The communication control unit 24 may determine that the communication device 1 is in the initial state when the device ID is not stored in the storage unit 23.

  The communication control unit 24 identifies the application of the communication device 1 that has transmitted the device data, and determines that the communication device 1 is in the initial state when the identified application is an application that the communication device 1 executes in the initial state. May be. The communication control unit 24 transmits the device data output by the application executed in the initial state of the communication device 1 with higher priority than the device data output by the application executed in the non-initial state of the communication device 1.

  For example, if the communication control unit 24 determines that the device data received by the device communication unit 21 is data to be transmitted in the initial state, the communication control unit 24 transmits the device data within a first time after receiving the device data. . If the communication control unit 24 determines that the device data received by the device communication unit 21 is data that is not transmitted in the initial state, the second time longer than the first time has elapsed since the device data was received. Send device data. By doing so, it is possible to preferentially transmit device data transmitted in a state where the initial setting of the communication device 1 has not been completed, and to reduce the probability that the communication network N1 is congested.

  The communication control unit 24 may determine the priority based on the combination of the device ID of the communication device 1 and the application ID of the application that has output the device data. For example, when the communication control unit 24 receives device data output from an application used in the initial setting from the communication device 1 in which the device ID is not stored in the storage unit 23, the communication control unit 24 receives other device data. High priority.

  The communication control unit 24 may increase the priority of the device data received from the communication device 1 when specifying that an abnormality has occurred in the communication device 1. For example, when the device data received from the communication device 1 is data indicating the occurrence of an abnormal state, the communication control unit 24 transmits the data with higher priority than the data not indicating the occurrence of the abnormal state. In this way, the administrator of the communication device 1 can quickly recognize that an abnormality has occurred in the communication device 1.

  The communication control unit 24 may determine the priority based on a time zone for transmitting device data. For example, the communication control unit 24 determines whether or not to transmit device data with a priority according to the state of the communication device 1 in each time zone based on the degree of congestion for each time zone of the wireless communication line. For example, the communication control unit 24 is based on the state of the communication device 1 in a time zone in which the degree of congestion of the communication network N1 is a predetermined value or more and a time zone in which the frequency of retransmission of transmitted data is required is a predetermined value or more. The priority may be determined, and the device data may be transmitted without changing the priority according to the state of the communication device 1 in other time zones.

  Furthermore, when there are a plurality of device data having the same priority in the time zone in which the device data is transmitted with the priority according to the state of the communication device 1, the communication control unit 24 sets each device data within a predetermined time range. You may transmit at random timing. In addition, when there are a plurality of device data having the same priority, the communication control unit 24 may combine a plurality of device data before transmitting them. By doing so, for example, it is possible to prevent a large number of packets from being transmitted to the communication network N1 when a large number of communication devices 1 that have not been initially set up are activated at the same time. Can be suppressed.

  Further, the communication control unit 24 may determine the priority based on the radio wave condition of the frequency band used in the wireless communication line from when the device data is received until the device data is transmitted. For example, the communication control unit 24 determines the priority based on the state of the communication device 1 when the S / N ratio of the radio wave to be used is smaller than a predetermined threshold, and in other time zones, the communication device The device data is transmitted without changing the priority according to the state of 1. In this way, the communication terminal 2 can quickly transmit device data having a high priority even when the radio wave condition is poor.

  In the above description, the communication device 1 has been described with a focus on an example in which the communication device 1 uses the initial setting state. However, the communication terminal 2 has other various states as the state of the communication device 1. Can be used. The communication terminal 2 may increase the priority when, for example, device data indicating that the communication device 1 has moved is transmitted from the communication device 1 that is assumed not to move. By doing so, for example, the data acquirer who monitors the state of the vending machine has stolen money in the vending machine because the communication device 1 installed in the vending machine vibrates. Can be detected quickly.

[Configuration of Data Management Device 3]

The storage unit 32 stores a communication terminal database (hereinafter referred to as a communication terminal DB) in which a communication terminal ID is associated with a device ID of the communication device 1 in which each communication terminal 2 can directly communicate without going through the base station 5. I remember it.

  FIG. 6 is a diagram illustrating an example of the communication terminal DB. In the communication terminal DB, in association with the communication terminal ID, the application ID that is the identification information of the application that can be executed by the communication device 1 that can communicate with the communication terminal 2, and the transmission that each application transmits at the time of one data transmission The amount of data is stored.

  In the example illustrated in FIG. 6, the communication terminal 2 with the communication terminal ID 9001 receives data output from the communication device 1 a with the device ID 1001 and the communication device 1 b with the device ID 1002. The communication device 1a can execute an application whose application ID is a51 whose transmission data amount is 10 bytes and an application whose application ID is a52 whose transmission data amount is 20 bytes. The communication device 1b can execute an application whose application ID is a51 whose transmission data amount is 10 bytes and an application whose application ID is a53 whose transmission data amount is 45 bytes.

  The storage unit 32 stores data transmitted from the plurality of communication devices 1 received from the communication terminal 2 in association with the device ID of the communication device 1. Further, the storage unit 32 includes the acquirer ID of the data acquirer who accesses the data management device 3 via the data acquisition device 4, and the communication device 1 and the device ID of the application registered as targets for the data acquirer to acquire data. And a data providing database (hereinafter referred to as a data providing DB) associated with the application ID may be stored.

The control unit 33 is a CPU, for example, and determines the timing at which each communication terminal 2 transmits data by executing a program stored in the storage unit 32.
The control unit 33 includes a communication control unit 331, a request reception unit 332, a storage control unit 333, and a timing determination unit 334.

  The communication control unit 331 controls data transmission / reception with the communication terminal 2. The communication control unit 331 notifies an APN (Access Point Name) which is a gateway address of the communication network N1 to the communication terminal 2 that can communicate with the communication device 1 that outputs data to be provided to the data acquisition device 4. Thus, reception of data from the communication terminal 2 is started. Further, the communication control unit 331 functions as a transmission unit that transmits timing information indicating the timing determined by the timing determination unit 334 to the communication terminal 2 via the first communication unit 311.

  The request receiving unit 332 receives a request for selecting the communication device 1 and the application from which data is acquired from the data acquisition device 4. The request reception unit 332 transmits, via the second communication unit 312, a list of communication devices 1 and applications for which the data management device 3 collects data to the data acquisition device 4.

  When the data acquirer selects the communication device 1 and application from which data is to be acquired from the list of communication devices 1 and applications displayed via the data acquisition device 4, the data acquisition device 4 selects the selected communication device 1 and A data acquisition request including information (for example, device ID and application ID) for specifying an application and an acquirer ID is transmitted to the data management apparatus 3. When receiving a data acquisition request from the data acquisition device 4, the request reception unit 332 notifies the storage control unit 333 of the acquirer ID, device ID, and application ID included in the data acquisition request, thereby allowing the data in the storage unit 32 to be stored. Register in the DB for provision.

  When receiving a request for acquiring data from the data acquisition device 4, the request reception unit 332 refers to the data provision DB stored in the storage unit 32 and received via the communication network N 1. The data transmitted by the application indicated by is provided by transmitting to the data acquisition device 4. In the data providing DB, the acquirer ID corresponding to the data acquisition device 4 that transmitted the data acquisition request is associated with the device ID of the communication device that is the target of providing data to the data acquisition device 4 of the acquirer ID. Yes. In the data providing DB, an application ID of an application to be provided with data may be further associated with the data acquisition device 4 having the acquirer ID.

  The request receiving unit 332 may receive a request for selecting the same application executed by the same communication device 1 from the plurality of data acquisition devices 4. When the request reception unit 332 receives a request for selecting the same application executed by the same communication device 1 from the plurality of data acquisition devices 4, the communication control unit 331 receives the data received via the communication network N <b> 1. Among them, the data indicated by the application indicated by the request is provided to the plurality of data acquisition devices 4.

  The storage control unit 333 writes data in the storage unit 32 or reads data stored in the storage unit 32 based on instructions from the communication control unit 331 and the request reception unit 332. For example, the storage control unit 333 causes the storage unit 32 to store device data received by the communication control unit 331 from the communication terminal 2 in association with the device ID and the application ID.
