Is generally connected to the terminal.

Japanese Unexamined Patent Publication No. 2012-014722

However, in the technology of setting the peripheral device to the pairing mode and then selecting the peripheral device to be connected from the terminal to connect to the appropriate partner device, as shown in FIG. 1 (a), the peripheral device user Before the connection with the terminal 1 is established, even the terminals 2 and 3 of other users may be able to connect to the peripheral device by requesting the connection to the peripheral device.

In addition, advertising packets are sent from the peripheral device set in the pairing mode, and it is necessary for all peripheral terminals to perform processing such as determining whether the peripheral device of the transmission source is an appropriate partner device. It is long-awaited to control so that the above processing can be executed only by the terminal to be connected, not by all the peripheral terminals.

Therefore, in the present disclosure, regarding the connection between the terminal and the peripheral device, the peripheral device is prevented from connecting to the terminal other than the user's terminal of the peripheral device, and the processing after receiving the advertising packet is executed only by the terminal to be connected. The purpose.

The device management system according to the present disclosure is a device management system that includes a terminal and a peripheral device, and performs mutual device authentication (pairing) between the terminal and the peripheral device, and is the peripheral device. The device inserts the acquired terminal ID of the terminal to be connected to the peripheral device or the user ID of the user who uses the peripheral device into the advertising packet as the destination information, and sends out the advertised packet after the insertion. The terminal includes a request reception processing unit that receives a connection request from the terminal and executes processing according to the connection request, and the terminal is a packet reception unit that receives an advertising packet transmitted by the packet transmission unit. , A determination unit that determines whether or not the destination information inserted in the received advertising packet matches the ID related to the own machine, and if the destination information matches the ID related to the own machine, the connection request is related. Includes a connection request unit that executes processing.

In the above device management system, the packet transmission unit of the peripheral device inserts the acquired terminal ID or user ID into the advertising packet as destination information, and sends the inserted advertising packet. In terminals near peripheral devices, when the packet receiving unit receives the transmitted advertising packet, the judgment unit determines that the destination information inserted in the received advertising packet is the ID (terminal ID or user) related to the own device. It is determined whether or not it matches with ID). Here, when the destination information matches the ID related to the own device, the connection request unit executes the process related to the connection request (for example, transmission of the connection request to the peripheral device), and the request reception processing unit of the peripheral device executes the process. , When a connection request from the terminal is received, the process corresponding to the connection request is executed.

The advertising packet sent from the peripheral device in this way includes the terminal ID of the terminal connected to the peripheral device or the user ID of the user who uses the peripheral device as the destination information. Therefore, the terminal determines whether or not the destination information matches the ID related to itself, and if it matches, the terminal executes a process related to the connection request (for example, transmission of a connection request to a peripheral device) to perform peripheral operations. It is possible to prevent the device from connecting to a terminal other than the user's terminal of the peripheral device. In addition, in the terminal, the suitability of the connection can be easily determined only by determining whether or not the destination information of the advertising packet matches the ID related to itself, and only the terminal related to the destination information (the terminal to be connected). It is possible to execute the processing after receiving the advertising packet with.

According to the present disclosure, regarding the connection between the terminal and the peripheral device, it is possible to prevent the peripheral device from connecting to a terminal other than the user's terminal of the peripheral device, and to execute the processing after receiving the advertising packet only on the terminal to be connected. can.

Hereinafter, an embodiment of the device management system according to the present disclosure will be described with reference to the drawings.

As shown in FIG. 1 (b), in the device management system according to the present disclosure, the peripheral device inserts the acquired terminal ID or user ID into the advertising packet as destination information, and sends out the inserted advertising packet. There is a feature. Therefore, in the terminals 1 to 3 that have received the advertising packet, the suitability of the connection can be determined only by determining whether or not the destination information inserted in the advertising packet matches the ID (terminal ID or user ID) related to the own machine. It can be easily judged. As a result, it is possible to execute the process related to the connection request (for example, transmission of the connection request to the peripheral device) only by the terminal (terminal 1) of the user of the peripheral device. Further, the peripheral device is configured not to accept the connection request because the ID does not match the destination information even if the connection request comes from the terminals 2 and 3 other than the terminal 1.

Hereinafter, a specific configuration example of the device management system will be described with reference to FIG.

As shown in FIG. 2, the device management system 1 includes a terminal 20 and a peripheral device 10, and mutual device authentication (pair) between the terminal 20 and the peripheral device 10 by short-range wireless communication (BLE or the like). Ring) is executed.

The peripheral device 10 includes an ID acquisition unit 11, a packet transmission unit 12, and a request reception processing unit 13. The ID acquisition unit 11 is a functional unit that acquires the terminal ID of the terminal to be connected to the peripheral device 10 or the user ID of the user who uses the peripheral device 10, and is, for example, a management terminal operation in advance (when purchasing the peripheral device, etc.). The above terminal ID or user ID may be acquired by such means, or when pairing is executed from a server or the like on the cloud that stores the above terminal ID or user ID in advance (when purchasing peripheral devices, etc.). You may get it in.

The packet sending unit 12 is a functional unit that inserts the terminal ID or the user ID into the advertising packet as destination information at the time of pairing execution, and sends out the inserted advertising packet.

The request reception processing unit 13 receives the connection request from the terminal 20 and processes according to the connection request (for example, confirmation that the information of the connection request transmission source matches the destination information, and a connection request when the information matches the destination information. It is a functional part that executes (such as acceptance of).

The terminal 20 includes a packet receiving unit 21, a determination unit 22, and a connection requesting unit 23. The packet receiving unit 21 is a functional unit that receives the advertising packet transmitted by the packet transmitting unit 12.

The determination unit 22 is a functional unit that determines whether or not the destination information (terminal ID or user ID) inserted in the received advertising packet matches the ID related to the own machine.

The connection request unit 23 is a functional unit that executes processing related to the connection request (for example, display of peripheral device selection screen, acceptance of selection, transmission of connection request, etc.) when the destination information matches the ID related to the own machine. be. The connection request transmitted from the connection request unit 23 is received by the request reception processing unit 13 of the peripheral device 10, and the processing corresponding to the connection request described above is executed.

Hereinafter, a specific processing example executed by the device management system 1 will be described with reference to FIG.

First, the ID acquisition unit 11 of the peripheral device 10 acquires the terminal ID of the terminal to be connected to the peripheral device 10 or the user ID of the user who uses the peripheral device 10 (step S1). Such ID acquisition may be acquired in advance (at the time of purchasing peripheral devices, etc.) by operating a management terminal or the like, or may be paired from a server on the cloud in which the terminal ID or user ID is stored in advance. It may be acquired when the ring is executed.

When the user sets the peripheral device 10 to the pairing mode by a predetermined operation, the packet sending unit 12 inserts the terminal ID or the user ID into the advertising packet as destination information, and sends out the inserted advertising packet (step S2). ..

The transmitted advertising packet reaches the peripheral terminal 20, the packet receiving unit 21 receives the advertising packet at the terminal 20 (step S3), and the determination unit 22 inserts the destination information (terminal ID) into the received advertising packet. Alternatively, it is determined whether or not the user ID) matches the ID related to the own machine (step S4). Here, if the destination information does not match the ID related to the own machine, it can be determined that the own machine is not a pairing target, so the process ends without making a connection request or the like.

On the other hand, if the destination information matches the ID related to the own machine in step S4, it can be determined that the own machine is a pairing target, so that the connection request unit 23 executes the process related to the connection request described later (step). S5). Here, for example, the connectable device list screen shown in FIG. 4A is displayed, and the user is made to select the peripheral device to be connected. When the user selects, for example, "Device 1", the connection request unit 23 accepts the selection and sends a connection request to "Device 1" (selected peripheral device). At this time, as shown in FIG. 4B, the selected "Device 1" is displayed as "pairing", and the user is informed of the processing status of "pairing".

In the peripheral device 10 (Device 1) that is the destination of the connection request, the request reception processing unit 13 receives the connection request, and the information (terminal ID or user ID) of the connection request transmission source is processed according to the connection request. Confirms that it matches the destination information inserted in the advertising packet transmitted in step S2 (step S6), accepts the connection request only when it matches (step S7), and realizes pairing with the terminal 20. On the other hand, in the case of a mismatch, it can be determined that the connection request is not from an appropriate terminal, so the reception of the received connection request is avoided and the process is terminated.

As described above, by transmitting the advertising packet transmitted from the peripheral device 10 including the terminal ID or the user ID as the destination information, the terminal 20 determines whether or not the destination information matches the ID related to itself. If they match, the process related to the connection request is executed, and if they do not match, the process related to the connection request is avoided to prevent the peripheral device from connecting to a terminal other than the user's terminal of the peripheral device. Can be done. In addition, in the terminal, the suitability of the connection can be easily determined only by determining whether or not the destination information of the advertising packet matches the ID related to itself, and only the terminal related to the destination information (the terminal to be connected). It is possible to execute the processing after receiving the advertising packet with.

If the destination information matches the ID related to the own machine, in step S5 of FIG. 3, as "processing related to the connection request", a screen for selecting a peripheral device to be the other device is displayed and the user is made to select. By sending a connection request to the selected peripheral device, the user can be given an opportunity to select the peripheral device, and proper peripheral device-terminal pairing can be realized.

However, in step S5 of FIG. 3, as another option, when the destination information matches the ID related to the own machine, a screen for selecting a peripheral device to be the other device is displayed as "processing related to the connection request". Instead, a mode may be adopted in which the connection request is transmitted to the peripheral device from which the advertising packet is sent. That is, since the advertising packet including the destination information (terminal ID or user ID) is transmitted from the peripheral device 10 by the user operation, it is considered that the selection of the peripheral device to be the partner device of the terminal is not essential. In this case, the user can save the trouble of selecting the peripheral device to be the other device from the screen of the terminal, and can save labor.

Further, in steps S6 and S7 of FIG. 3, in the peripheral device 10, as "processing according to the connection request", it is confirmed that the information of the source of the connection request matches the destination information, and the connection is made only when the information matches. By accepting the request, if there is a mismatch (in the case of a connection request from an unauthorized terminal), it is possible to avoid accepting the connection request and prevent pairing with the unauthorized terminal.
