[Flow of processing at the time of pairing]
First, the flow of processing at the time of pairing performed when monitoring of the second communication terminal 2 is started by the first communication terminal 1 will be described. FIG. 4 is a flowchart showing the flow of processing at the time of pairing.

  First, the first reception unit 161 of the first communication terminal 1 receives an instruction for monitoring the communication status of wireless communication with the second communication terminal 2 by the first communication unit 13. Specifically, in response to having received the display request for the monitoring screen for monitoring the second communication terminal 2 through the input unit 11, the first receiving unit 161 displays the monitoring screen on the display unit 12 Display on.

  FIG. 5 is a diagram showing an example of the monitoring screen. In the example illustrated in FIG. 5, a fan-shaped distance notification image A indicating an approximate distance from the first communication terminal 1 to the second communication terminal 2 and an object P indicating the first communication terminal 1 are displayed. In the example shown in FIG. 5, “ON” is displayed, an on button for receiving a monitoring instruction, and “off” displayed as “OFF”, and an off button for receiving a monitoring end instruction for ending the monitoring are provided. ing.

  The first accepting unit 161 determines whether or not an on button is pressed on the monitoring screen and a monitoring instruction has been received (S1). If the first accepting unit 161 determines that the monitoring instruction has been accepted, the process proceeds to S2, and if it is determined that the monitoring instruction is not accepted, the first accepting unit 161 re-executes S1.

  When the first reception unit 161 receives a monitoring instruction, the acquisition unit 162 of the first communication terminal 1 acquires the second telephone number from the second communication terminal 2. Further, the acquiring unit 262 of the second communication terminal 2 acquires the first telephone number from the first communication terminal 1.

Specifically, the acquisition unit 162 of the first communication terminal 1 causes the first communication unit 13 to transmit a search signal for searching the second communication terminal 2 (S2).
When the acquisition unit 262 of the second communication terminal 2 receives a search signal (S3), the acquisition unit 262 causes the first communication unit 23 to transmit a response signal corresponding to the search signal (S4).

  When the acquisition unit 162 of the first communication terminal 1 receives the response signal from the second communication terminal 2 (S5), the first telephone stored in the storage unit 15 of the first communication terminal 1 is a telephone number assigned to itself. The number is acquired (S6) and transmitted to the second communication terminal 2 (S7).

When the acquisition unit 262 of the second communication terminal 2 receives the first telephone number (S8), the storage control unit 263 stores the first telephone number in the storage unit 25 (S9).
In addition, the acquisition unit 262 of the second communication terminal 2 acquires the second telephone number, which is a telephone number assigned to itself, stored in the storage unit 25 of the second communication terminal 2 (S10). To (S11).

  When the acquisition unit 162 of the first communication terminal 1 receives the second telephone number (S12), the storage control unit 163 sets the second telephone number as a target for monitoring the communication status of the wireless communication by the first communication unit 13. The storage unit 15 is stored as terminal identification information for identifying the designated second communication terminal 2 (S13). Thereby, pairing of the first communication terminal 1 and the second communication terminal 2 is completed, and the monitoring of the communication state of the wireless communication with the second communication terminal 2 by the first communication unit 13 is started.

[Flow of processing during monitoring]
Subsequently, the communication control unit 164 of the first communication terminal 1 monitors the communication status of the wireless communication with the second communication terminal 2 by the first communication unit 13. Then, based on the communication status of the wireless communication with the second communication terminal 2 by the first communication unit 13, the communication control unit 164 causes the second communication unit 14 to execute the second based on the terminal identification information (second telephone number). Wireless communication with the communication terminal 2 is performed. FIG. 6 is a flowchart showing a flow of processing when monitoring the communication status of the wireless communication with the second communication terminal 2 by the first communication unit 13.

First, the communication control unit 264 of the second communication terminal 2 causes the first communication unit 23 to transmit a beacon signal (S21). The first communication unit 23 transmits, for example, a beacon signal including the user ID of the watching target in the beacon ID.
The notification unit 166 of the first communication terminal 1 notifies the watcher of the degree of separation between the first communication terminal 1 and the second communication terminal 2 based on the reception status of the beacon signal by the first communication unit 13 (S22) .

  Specifically, when the first communication unit 13 receives the beacon signal, the notification unit 166 acquires, from the first communication unit 13, information indicating the reception strength of the radio wave corresponding to the beacon signal, and the reception strength The degree of separation from the second communication terminal 2 is determined based on the information indicating. The notification unit 166 causes the object W indicating the second communication terminal 2 to be displayed based on the determined degree of separation within the sector-shaped distance notification image A displayed on the monitoring screen.

  FIG. 7 is a diagram showing an example of notification of the degree of separation by the monitoring screen. It can be confirmed in FIG. 7A that the object W indicating the second communication terminal 2 is displayed. If the degree of separation from the second communication terminal 2 is small, the notification unit 166 causes the object W to be displayed at a position near the object P indicating the first communication terminal 1, and the degree of separation from the second communication terminal 2 is large. In this case, the object W is displayed at a position far from the object P.

  In addition, when the first communication unit 13 receives no beacon signal, or when the field intensity of the radio wave received by the first communication unit 13 from the second communication terminal 2 is less than or equal to a predetermined threshold, the notification unit 166 It is estimated that the distance between the first communication terminal 1 and the second communication terminal 2 is equal to or greater than the communicable distance (predetermined distance) of the first communication unit 13. In this case, the notification unit 166 hides the object W as shown in FIG. 7 (b).

Subsequently, the communication control unit 164 of the first communication terminal 1 determines whether the first communication unit 13 has received a beacon signal (S23). If the communication control unit 164 determines that the beacon signal is received, the process proceeds to S24. If it is determined that the beacon signal is not received, the process proceeds to S25.
In S24, the communication control unit 164 causes the first communication unit 13 to transmit a response signal of the beacon signal. The first communication unit 13 transmits, for example, a response signal including the user ID of the watcher. Thereafter, the communication control unit 164 shifts the processing to S22.

  In S25, the communication control unit 164 determines whether or not a predetermined time (for example, 10 seconds) has elapsed since the first communication unit 13 last received the beacon signal. If the communication control unit 164 determines that the predetermined time has elapsed since the last reception of the response signal, the process proceeds to S26, and if it is determined that the predetermined time has not elapsed since the last reception of the response signal, Transfer the process to S22.

  In S26, when a predetermined time has elapsed since the first communication unit 13 last received the beacon signal, the second reception unit 165 determines that the communication state of the first communication terminal 13 is the first communication terminal 1 It determines with having changed into the communication condition which shows that it is separated from the 2nd communication terminal 2 and more than predetermined distance. Then, the second reception unit 165 causes the display unit 12 to display a warning screen for receiving an instruction to start wireless communication with the second communication terminal 2 by the second communication unit 14. The process after displaying the warning screen will be described later.

  The notification unit 266 of the second communication terminal 2 notifies the target person of the separation degree between the first communication terminal 1 and the second communication terminal 2 based on the reception status of the response signal by the first communication unit 23 (S27) ). Similar to the notification unit 166 of the first communication terminal 1, the notification unit 266 acquires information indicating the reception intensity of the radio wave corresponding to the response signal from the first communication unit 23, and based on the information indicating the reception intensity, The degree of separation from the first communication terminal 1 is determined. Then, the notification unit 266 causes the display unit 22 to display a fan-shaped distance notification image in the same manner as, for example, the monitoring screen illustrated in FIG. 5, and the first notification based on the determined separation degree inside the distance notification image. An object indicating the communication terminal 1 is displayed.

  Subsequently, the communication control unit 264 of the second communication terminal 2 determines whether the first communication unit 23 receives the response signal (S28). If the communication control unit 264 determines that the response signal is received, the process proceeds to S21, and if it is determined that the response signal is not received, the process proceeds to S29.

  In S29, the communication control unit 264 determines whether or not a predetermined time (for example, 10 seconds) has elapsed since the first communication unit 23 last received the response signal. If the communication control unit 264 determines that the predetermined time has elapsed since the last reception of the response signal, the process proceeds to S30, and if it is determined that the predetermined time has not elapsed since the last reception of the response signal, Transfer the process to S21.

  In S30, when a predetermined time has elapsed since the first communication unit 23 last received the response signal, the reception unit 265 determines that the communication condition of the wireless communication by the first communication unit 23 is the second communication terminal 2 It is determined that the communication status has changed to a communication status indicating that the communication terminal 1 is separated by a predetermined distance or more. Then, the reception unit 265 causes the display unit 22 to display a warning screen for receiving an instruction to start wireless communication with the first communication terminal 1 by the second communication unit 24.

[Process after displaying warning screen]
Subsequently, processing after the warning screen is displayed will be described.
The second reception unit 165 of the first communication terminal 1 determines that the communication state of the wireless communication by the first communication unit 13 indicates that the first communication terminal 1 is separated from the second communication terminal 2 by a predetermined distance or more. When it changes, a warning screen for accepting an instruction to start wireless communication with the second communication terminal 2 by the second communication unit 14 is displayed on the display unit 12 and the start instruction is accepted. In addition, the second reception unit 165 outputs a warning sound from a speaker (not shown) included in the first communication terminal 1 so that the watcher leaves the watch target person carrying the second communication terminal 2 away from himself. Notify that.

  FIG. 8 is a diagram showing an example of the warning screen AL. As shown in FIG. 8, the warning screen AL is displayed superimposed on the monitoring screen. A warning button AL is displayed on the warning screen AL, and a first button for receiving an instruction to start wireless communication with the second communication terminal 2 by the second communication unit 14 and a message "Stop sound" are displayed. A second button for receiving the output stop of and a third button for displaying an “end” and receiving an instruction to hide the warning screen AL are provided.

  When the first button is selected, and communication control unit 164 receives an instruction to start wireless communication with second communication terminal 2 by second communication unit 14, communication control unit 164 causes second communication unit 14 to execute a second communication based on the second telephone number. Wireless communication with the communication terminal 2 is performed. Specifically, when the communication control unit 164 receives the start instruction, the communication control unit 164 controls the second communication unit 14 to call the second telephone number stored in the storage unit 15 at the time of pairing. The receiving unit 265 of the second communication terminal 2 causes the display unit 22 to display that the first communication terminal 1 has received a call, in response to the call being received. When the watching target operates the second communication terminal 2 and performs an operation to start a call, the second communication unit 14 of the first communication terminal 1 and the second communication unit 24 of the second communication terminal 2 are wireless Start communication.

  Similarly, the reception unit 265 of the second communication terminal 2 causes the display unit 22 to display a warning screen for receiving an instruction to start wireless communication with the first communication terminal 1 by the second communication unit 24, and receives the start instruction. In addition, the receiving unit 265 outputs a warning sound from a speaker (not shown) included in the second communication terminal 2 so that the watching target person is separated from the watching person who owns the first communication terminal 1 by the watching target person. To notify.

  The reception unit 265 displays a warning screen provided with a first button, a second button, and a third button, similarly to the warning screen AL shown in FIG. 8, and displays the first communication terminal 1 by the second communication unit 24. Accept an instruction to start wireless communication with the Note that on the second communication terminal 2 side, the warning screen may not display a third button for receiving an instruction to hide the warning screen. By doing this, the second communication terminal 2 does not hide the warning screen, so the watching target selects the first button displayed on the warning screen and starts communication with the watcher. Can increase the possibility of

  When the communication state of the wireless communication by the first communication unit 23 changes to a communication state indicating that the second communication terminal 2 is separated from the first communication terminal 1 by a predetermined distance or more, the notification unit 266 transmits the second communication terminal 2. The second communication terminal 2 is notified that the watching target person carrying the call has left the watching person. For example, after the warning screen is displayed, the notification unit 266 displays that the watching target has separated from the watching person in response to the fact that the warning screen is not operated for a predetermined time (for example, one minute). A notification screen showing information indicating the information and information indicating the identity of the watching target is displayed on the display unit 22 and a warning sound is output from the speaker, and the second watching communication terminal indicates that the watching target is separated from the watching person Notify around 2 By doing this, it is possible to make the third party notice that the watching target has left the watching person and to increase the possibility of taking appropriate action on the third party.

  The first communication terminal 1 and the second communication terminal 2 are warned at the same timing by displaying the warning screen based on the signal that the first communication terminal 1 and the second communication terminal 2 mutually transmit and receive. There is a high possibility of displaying the screen. In this case, the watching person and watching target person become talking by giving an instruction to start wireless communication by the second communication unit at the same timing on the warning screen, and the watching person and watching target person can not communicate. There is a fear.

  Therefore, display timings of warning screens in the first communication terminal 1 and the second communication terminal 2 may be different from each other. For example, in the first communication terminal 1, a warning screen is displayed in response to the passage of a first time (for example, 10 seconds) since the first communication unit 13 last received a beacon signal, and the second communication terminal 2 In the above, the warning screen may be displayed in response to the elapse of a second time (for example, 20 seconds) since the first communication unit 23 last received the response signal. In addition, the first communication terminal 1 and the second communication terminal 2 have different times until it becomes possible to select the first button for accepting the start instruction of the wireless communication by the second communication unit displayed on the warning screen. You may control.

  The first communication terminal 1 warns that the communication state of the wireless communication by the first communication unit 13 changes to a communication state indicating that the first communication terminal 1 is separated from the second communication terminal 2 by a predetermined distance or more.
