  The audio processing unit 60 executes processing of an audio signal input to the microphone 54 and an audio signal output from the speaker 55 and the receiver 56.

  The switch member 61 is disposed on the upper side of the housing and is connected to the strap 51. The switch member 61 has a structure that can move with respect to the casing when the strap 51 is pulled with respect to the casing. The user operates the switch member 61 using the strap 51 as a clue. When the switch member 61 is pulled by the strap 51, the switch member 61 moves so as to protrude from the upper surface of the housing. The switch member 61 is configured to be able to switch and move between an initial position and a protruding position moved from the initial position by being pulled by the strap.

  The switch position detector 62 detects the operation state of the subject, specifically, the position of the switch member 61. When the switch member 61 is in the initial position, the switch position detection unit 62 outputs a first operation signal to the control unit 70 assuming that the operation state is the first operation state. Further, when the switch member 61 is in the protruding position, the switch position detection unit 62 outputs a second operation signal to the control unit 70 assuming that the operation state is the second operation state. The control unit 70 specifies the position of the switch member 61 based on whether the first operation signal is output from the switch position detection unit 62 or the second operation signal is output. The switch position detection unit 62 may not output an operation signal when the switch position is in the initial position, and may output an operation signal only when the switch member 61 is in the protruding position.

  The GPS communication unit 64 is a communication unit that receives a GPS signal output from the GPS satellite 2. The GPS communication unit 64 calculates the latitude / longitude of the second portable communication device 50 by receiving and analyzing the output GPS signal, and sends the calculated latitude / longitude information to the control unit 70. Specifically, the GPS communication unit 64 acquires GPS signals from a plurality of GPS satellites 2, and the time difference between the time information included in the GPS signals and the acquired time information, the intensity of the received propagation radio wave, etc. The distance from the GPS satellite 2 is calculated. The GPS communication unit 64 calculates its own position by analyzing the distance from the GPS satellite 2 and the position information of each GPS satellite 2.

The control unit 40 is composed of, for example, a microprocessor unit, sequentially reads instruction codes from a program stored in the storage unit 68, and performs various processes of the second mobile phone 50 in accordance with the procedures instructed by the read instruction codes. Run.

  Specifically, when the user pulls the strap 51 and the switch position detection unit 62 detects that the switch member 61 has moved to the protruding position, the control unit 70 outputs a buzzer sound for crime prevention from the speaker 55, An e-mail indicating that the crime prevention function has been activated is transmitted to the first mobile phone. When the control unit 70 receives a reply request for notification of position information from the first mobile phone 10 via the communication unit 58, the control unit 70 executes position positioning, and the position information obtained by the positioning is transmitted to the first mobile phone 10 by the communication unit 58. Send back. When the predetermined condition is satisfied, the control unit 70 performs pairing processing with the first mobile phone 10 at the short-range communication unit 66. Here, the pairing processing is processing for exchanging necessary information when a target communication device is searched and found so that communication with the target communication device can be performed by short-range wireless communication. For example, the control unit 70 outputs (transmits) a search request to surrounding communication devices by the short-range communication unit 66. That is, the control unit 70 outputs a search request within a range in which a short-range wireless communication signal reaches by the short-range communication unit 66. The search request is a signal for searching for a communication device within the range in which the second mobile phone 50 can communicate by short-range wireless communication. The communication device that has acquired the search request transmits its own unique number (MAC address) to the second mobile phone 50 that has output the search request. The short-range communication unit 66 receives the transmitted unique number. When there is a response including the unique number of the target communication device in the received unique number, the control unit 70 establishes communication using the short-range communication with the communication device that has output the unique number. I do. When the pairing process is successful and communication is established, the control unit 70 can transmit / receive information to / from the communication device by the short-range wireless communication using the short-range communication unit 66.

  As described above, the second mobile phone 50 detects the position information when the crime prevention function is activated, when there is a reply request from the first mobile phone 10, or when a preset condition is satisfied. The obtained position information is sent to the specific first mobile phone 10. If the condition set by the first mobile phone 10 is satisfied, the second mobile phone 50 may detect the position information and send the detected position information to the specific first mobile phone 10. Examples of the set condition include a time condition such as a period or a time zone, and a position condition such as going out of a set range.

  The second mobile phone 50 determines to execute position information detection processing due to a specific condition set in advance and to send the detected position information to the specific first mobile phone 10, that is, position information transmission processing. In this case, the pairing process with the first mobile phone 10 is executed by the short-range communication unit 66 before the process is executed. When the short-range communication unit 66 can establish communication with the first mobile phone 10, the second mobile phone 50 detects the position information and sends the detected position information to the specific first mobile phone 10. do not do.

  Hereinafter, the operation of the communication system 1, particularly the processing operation executed by the specific first mobile phone 10 and the specific second mobile phone 50 associated with each other will be described with reference to FIGS. 7 to 12. An example of processing executed between the first mobile phone 10 and the second mobile phone 50 will be described with reference to FIGS. 7 and 8. 7 and 8 are diagrams illustrating an example of processing executed between the first mobile phone and the second mobile phone, respectively. FIG. 7 shows only the communication unit 100 of one first mobile phone 10 and one second mobile phone 50 in the communication system 1. The first mobile phone 10 and the second mobile phone 50 are associated with each other in advance and are set to execute a specific process. In the communication unit 100, the first mobile phone 10 is a parent terminal, and the second mobile phone 50 is a child terminal. The communication unit 100a shown in FIG. 8 includes the same first mobile phone 10 and second mobile phone 50 as the communication unit 100, and shows a state in which some processing results are different.

  Hereinafter, the present embodiment will be described as a case where an earthquake early warning is received as a predetermined notification. Various notifications can be used as the predetermined notification. As the predetermined notification, it is preferable to use an e-mail including emergency information. As e-mails including emergency information, there are notification-type predetermined e-mails (messages) such as emergency earthquake warnings and tsunami warnings distributed by the Japan Meteorological Agency, disaster information and evacuation information transmitted by local governments, and the like. The first mobile phone 10 can determine whether or not the email includes emergency information by analyzing at least one of the information included in the header of the received email, the text information, and the email type. . For example, the received e-mail may be a broadcast message of simultaneous delivery type using BCSMS or the like. The first mobile phone 10 is a broadcast message, and when the broadcast area of the extended system parameter of the received e-mail is set in the paging channel, the first mobile phone 10 is urgent by checking the signal described in the area. It is determined whether the message is a predetermined notification type message such as earthquake early warning. For example, the received electronic mail may be an area mail that is simultaneously distributed by a communication carrier. In this case, the first mobile phone 10 determines whether the message is a notification-type predetermined message such as an emergency earthquake warning by checking the parameters of the system area provided in the header of the area mail.

  As shown in FIG. 7, in the communication unit 100, the first mobile phone 10 receives the earthquake early warning as step S1. When the first mobile phone 10 receives the earthquake early warning in step S1, the communication unit 100 outputs a current position request command from the first mobile phone 10 to the second mobile phone 50 in step S2, and the first mobile phone The second mobile phone 50 receives the current position request command output from 10. That is, the first mobile phone 10 outputs a location information request for the second mobile phone 50 in step S2, and the second mobile phone 50 receives the location information request. The first mobile phone 10 can transmit the command to the second mobile phone 50 by including a command indicating the position information request in the e-mail. The first mobile phone 10 includes, in the e-mail, information indicating that the location information request is due to the earthquake early warning together with a command indicating the location information request. That is, the first mobile phone 10 sends an e-mail to the second mobile phone 50 that can detect that the command indicating the position information request has been transmitted by receiving the earthquake early warning. The relationship between the command and the process to be executed is stored in advance in both the first mobile phone 10 and the second mobile phone 50.

  When the second mobile phone 50 analyzes the e-mail including the location information request received in step S2 and determines that the location information request command is due to the earthquake early warning, as step S3, the pairing process, Processing for establishing communication using the short-range communication unit 66 is started. When the first mobile phone 50 transmits an e-mail including a command for requesting location information resulting from the earthquake early warning in step 2, the first mobile phone 50 establishes pairing processing, that is, communication using the short-range communication unit 33, in step S3. Start processing. The communication unit 100 executes pairing processing in both the first mobile phone 10 and the second mobile phone 50 in step S3, and performs communication by short-range communication between the first mobile phone 10 and the second mobile phone 50. If established, the process is terminated. That is, the communication unit 100 can establish communication by short-range communication and does not respond to the position information request when detecting that the first mobile phone 10 and the second mobile phone 50 are within a certain distance. The process is terminated.

  In contrast, the communication system 100a shown in FIG. 8 detects that pairing has failed in step S4. In other words, the communication system 100a detects that the first mobile phone 10 and the second mobile phone 50 cannot detect the communication device of the other party through short-range communication and cannot establish communication through short-range communication. .

  If the second mobile phone 50 detects a pairing failure in step S4, it receives a GPS signal and acquires position information of the second mobile phone 50, that is, its own device, in step S5. The second mobile phone 50 acquires a GPS signal by the GPS communication unit 64, analyzes the acquired GPS signal, and acquires information on the current position of the own device.

  When the second mobile phone 50 obtains its own location information in step S5, the communication unit 100a returns the location information of the second mobile phone 50 from the second mobile phone 50 to the first mobile phone 10 in step S6. . That is, the second mobile phone 50 transmits the position information acquired in step S2 to the first mobile phone 50. The second mobile phone 50 according to the present embodiment sends an e-mail including position information to the first mobile phone 50. The first mobile phone 10 receives the position information of the second mobile phone transmitted from the second mobile phone 50. The first mobile phone 10 according to the present embodiment receives the e-mail transmitted from the second mobile phone 50, thereby receiving the position information of the second mobile phone.

  Next, a process executed by the first mobile phone 10 that has acquired the position information of the second mobile phone 50 will be described with reference to FIG. FIG. 9 is a diagram illustrating an example of a screen displayed on the display unit of the first mobile phone. When the position information of the second mobile phone 50 is acquired, the first mobile phone 10 displays a map image 101 indicating the position of the second mobile phone 50 on the display 12 as shown in FIG. The map image 101 is a map of a range including position information of the second mobile phone 50. The map image 101 includes a mark 102. A mark 102 indicates the position of the second mobile phone 50.

  Next, processing executed by the second mobile phone 50 will be described with reference to FIG. FIG. 10 is a flowchart illustrating an example of processing executed by the second mobile phone. The processing shown in FIG. 10 can be realized by the control unit 70 of the second mobile phone 50 processing the program stored in the storage unit 68 and executing each operation.

  When the position information request is received as step S40, the control unit 70 executes a pairing process with the first mobile phone as step S42. After executing the pairing process in step S42, the control unit 70 determines whether the pairing is successful in step S44. That is, the control unit 70 determines whether or not communication by the short-range communication has been established with the first mobile phone 10 that has transmitted the position information request. If the control unit 70 determines in step S44 that the pairing has succeeded (Yes in step S44), that is, communication has been established, the process ends.

  When determining that pairing has failed (No in Step S44), that is, communication has not been established in Step S44, the control unit 70 receives a GPS signal and specifies the position in Step S46. That is, the control unit 70 receives a GPS signal using the GPS communication unit 64, processes the received GPS signal, and specifies the position of the second mobile phone 50. When the position is specified in step S46, the control unit 70 outputs the position information to the first mobile phone 10 in step S48, and ends this process. That is, the control unit 70 outputs the acquired position information to the specific first mobile phone 10 associated therewith. The output method of the position information is not particularly limited, but it is preferable to output it as an e-mail as described above.

  In the example illustrated in FIG. 10, the position information request is received in step S40, but step S40 is not limited to this. If it is determined that the second mobile phone 50 satisfies various conditions that serve as a trigger for transmitting the position information as described above, the second mobile phone 50 may perform the process of FIG.

  Next, processing executed by the first mobile phone 10 will be described with reference to FIG. FIG. 11 is a flowchart illustrating an example of processing executed by the first mobile phone. The processing shown in FIG. 11 can be realized by the control unit 40 of the first mobile phone 10 processing a program stored in the storage unit 34 and executing each operation.

  The control part 40 determines whether the emergency earthquake bulletin was received as step S50. When it is determined that the emergency earthquake bulletin has not been received in step S50 (No in step S50), the control unit 40 ends this process. If it is determined in step 50 that the earthquake early warning has been received (Yes in step S50), the control unit 40 transmits a location information request to the second mobile phone in step S52, and in step S54, Perform the pairing process. After executing the pairing process in step S54, the control unit 40 determines whether the pairing is successful in step S56. That is, the control unit 40 determines whether communication by the short-range communication has been established with the second mobile phone 10 that is the transmission destination of the position information request. If the control unit 40 determines in step S56 that the pairing has succeeded (Yes in step S56), that is, communication has been established, the process ends.

  When determining that the pairing has failed (No in Step S56), that is, communication has not been established in Step S56, the control unit 40 receives the position information transmitted from the second mobile phone as Step S58. That is, the control unit 40 acquires the position information of the second mobile phone in step S58. When the position information is received in step S58, the control unit 40 specifies the range and scale of the map based on the position of the second mobile phone 50 in step S60. Specifically, a range in which the position of the second mobile phone 50 enters is extracted, and a scale at which the extracted range is displayed on the display 12 is determined. The range of the map is determined so that the position of the second mobile phone 50 is located at a certain distance or more away from the end of the screen, that is, the end of the range. The range of the map may be determined so that the position of the second mobile phone 50 is within a certain distance from the center of the screen.

  After identifying the map range and scale in step S60, the control unit 40 extracts map data to be used in step S62. That is, the control unit 40 extracts map image data corresponding to the range and scale to be used. The map data may be stored in the storage unit 38 or may be acquired from an external communication device such as the server 3 by communication using the communication unit 28.

  After extracting the map data to be used in step S62, the control unit 40 adds the display of the position of the second mobile phone 50, that is, the display of the mark on the map data as step S64. If the display of a position is added by step S64, the control part 40 will be displayed on the display part 26 and the display 12 in this embodiment as step S66. The control part 40 complete | finishes this process, when a map is displayed by step S66.

  As described above, when the first mobile phone 10 receives the earthquake early warning, the communication system 1 causes the first mobile phone 10 to output a position information request from the first mobile phone 10 to the position of the second mobile phone 50. Execute the process to get. As a result, the communication system 1 allows the first mobile phone 10 possessed by the guardian to hold the position of the second mobile phone 50 possessed by the subject to be protected when the emergency earthquake bulletin has been filed, that is, when the urgency is high. You can be notified.

  The communication system 1 performs the pairing when the location information request is output from the first mobile phone 10 due to the earthquake early warning, and the pairing is successful, that is, the first mobile phone 10 and the second mobile phone 50 When communication by near field communication is established between the mobile phone and the mobile phone, position information is not transmitted from the second mobile phone 50 to the first mobile phone 10. When the first mobile phone 10 and the second mobile phone 50 are close to each other at the time of receiving the earthquake early warning, the communication system 1 does not perform transmission / reception of position information. As a result, when the guardian who possesses the first mobile phone 10 and the target person who possesses the second mobile phone 50 are together or in a position that can be immediately confirmed, information is transmitted via the network. Can be suppressed from being transmitted / received. Thereby, it can suppress that the positional information with low necessity is transmitted / received, and can improve operativity. Further, since it is possible to suppress the transmission and reception of information that is less necessary via the network, the load on the network can be reduced.

  When the pairing fails, the communication system 1 and the first mobile phone 10 acquire the location information of the second mobile phone 50 and display a map including the location information of the second mobile phone 50 as shown in FIG. . Thereby, the communication system 1 and the first mobile phone 10 can display the position of the second mobile phone 50. Thereby, the 1st mobile telephone 10 can show the position of the protection target person who is the user of the 2nd mobile telephone 50 in the state which is easy to understand with respect to the guardian who is a user.

  Here, when the pairing is established, the communication system 1, the first mobile phone 10, and the second mobile phone 50 preferably display a message indicating that the target mobile phone is nearby on the display unit. Thus, it is possible to know that the corresponding mobile phone is within a certain range without using communication via the communication unit. In addition, it is possible for the user to appropriately understand in a short time that the positional information is received and is not displayed.

  Here, the communication system 1 of the above embodiment has been described as the case where the first mobile phone 10 receives the emergency reception bulletin and executes the pairing process. However, the electronic system includes emergency information other than the emergency earthquake bulletin described above. A pairing process may also be executed for mail. The communication system 1 may execute the pairing process also when the first mobile phone 10 transmits a position information request due to a predetermined message set in advance, that is, triggered by reception.

  When the second mobile phone 50 of the communication system 1 of the above-described embodiment receives the position information request, the second mobile phone 50 performs the pairing process, but is not limited thereto. Hereinafter, the process executed by the second mobile phone 50 will be described with reference to FIG. FIG. 12 is a flowchart illustrating an example of processing executed by the second mobile phone. FIG. 12 shows a process for executing the pairing process when the second mobile phone receives the earthquake early warning.

  The control unit 70 determines whether an emergency earthquake bulletin has been received as step S70. When it is determined that the emergency earthquake bulletin has not been received in step S70 (No in step S70), the control unit 70 ends this process. When determining that the earthquake early warning has been received in Step S70 (Yes in Step S70), the control unit 70 executes pairing processing with the first mobile phone in Step S72. After executing the pairing process in step S62, the control unit 70 determines whether the pairing is successful in step S74. That is, the control unit 70 determines whether or not communication by the short-range communication has been established with the first mobile phone 10 that has transmitted the position information request. If the control unit 70 determines in step S74 that the pairing has succeeded (Yes in step S74), that is, determines that communication has been established, the control unit 70 ends this processing.

  When determining that pairing has failed (No in step S74), that is, communication has not been established in step S74, the control unit 70 receives a GPS signal and identifies the position in step S76. That is, the control unit 70 receives a GPS signal using the GPS communication unit 64, processes the received GPS signal, and specifies the position of the second mobile phone 50. When the position is specified in step S76, the control unit 70 outputs the position information to the first mobile phone 10 in step S78, and ends this process. That is, the control unit 70 outputs the acquired position information to the specific first mobile phone 10 associated therewith.

  As shown in FIG. 12, the second mobile phone 50 may execute a pairing process when receiving the earthquake early warning. The communication system 1 executes the pairing process between the first mobile phone 10 and the second mobile phone 50 when the second mobile phone 50 receives the earthquake early warning, and ends the processing when the pairing is successful. If pairing fails, position information may be transmitted. Thus, the communication system 1 allows the second mobile phone 50 to receive the earthquake early warning and the second mobile phone 50 is connected to the first mobile phone 10 even when the second mobile phone 50 is not near the first mobile phone 10. The location information of the telephone 50 can be notified.

  Thus, the communication system 1 may execute the pairing process even when a process other than the electronic mail transmitted from the first mobile phone 10 is executed. Specifically, when the process of transmitting location information from the second mobile phone 50 to the first mobile phone is executed, the pairing process may be executed before executing the location information transmission process.

  Here, the communication system 1 executes the pairing process regardless of the result of the pairing process when the user operates the operation unit of the first mobile phone 10 and acquires the position information of the second mobile phone 50. Instead, it is preferable to transmit the position information of the second mobile phone 50 to the first mobile phone 10. Accordingly, when the user of the first mobile phone 10 performs an operation for detecting the position of the second mobile phone 50, the position information can be acquired even when the second mobile phone 50 is nearby.

  It is preferable that the first mobile phone 10 and the second mobile phone 50 of the communication system 1 change the process to be executed according to the process that triggers the process of acquiring the position information of the second mobile phone.

The control unit 70 determines that the communication device that receives the earthquake early warning has started the position confirmation process using the earthquake early warning as a trigger in both the first mobile phone 10 and the second mobile phone 50.

  If the control unit 70 determines in step S112 that the instruction is based on the earthquake early warning (Yes in step S112), the control unit 70 proceeds to step S42. When it is determined in step S112 that the instruction is not based on the earthquake early warning (No in step S112), the control unit 70 determines whether to perform the pairing process in step S114. Specifically, the control unit 70 determines whether it is a process for executing the pairing process based on the process detected in step S110. When it is determined that the pairing process is not executed in Step S114 (No in Step S114), the control unit 70 proceeds to Step S46. When it is determined that the pairing process is to be executed in Step S114 (Yes in Step S114), the control unit 70 proceeds to Step S42.

  When it is determined Yes in steps S112 and S114, the control unit 70 performs pairing processing with the first mobile phone as step S42. After executing the pairing process in step S42, the control unit 70 determines whether the pairing is successful in step S44. That is, the control unit 70 determines whether or not communication by the short-range communication has been established with the first mobile phone 10 that has transmitted the position information request. If the control unit 70 determines in step S44 that the pairing has succeeded (Yes in step S44), that is, communication has been established, the process ends.

  When it is determined in step S44 that pairing has failed (No in step S44), that is, communication has not been established, or when it is determined No in step S114, the control unit 70 receives a GPS signal as step S46. , Locate. That is, the control unit 70 receives a GPS signal using the GPS communication unit 64, processes the received GPS signal, and specifies the position of the second mobile phone 50. When the position is specified in step S46, the control unit 70 outputs the position information to the first mobile phone 10 in step S48, and ends this process. That is, the control unit 70 outputs the acquired position information to the specific first mobile phone 10 associated therewith. The output method of the position information is not particularly limited, but it is preferable to output it as an e-mail as described above.

  Next, processing executed by the first mobile phone 10 will be described with reference to FIG. FIG. 14 is a flowchart illustrating an example of processing executed by the first mobile phone. The process shown in FIG. 14 can be realized by the control unit 40 of the first mobile phone 10 processing a program stored in the storage unit 34 and executing each operation.

  The control unit 40 detects that the position confirmation process is performed in step S120. Specifically, the control unit 40 determines whether it is detected that the process of detecting the position information of the second mobile phone 50 is started based on any one of the various triggers described above. Here, the process of step S120 does not include the process triggered by the reception of the earthquake early warning.

  When it is determined that the position confirmation process is to be executed in step S120 (Yes in step S120), the control unit 40 determines whether to transmit a position information request in step S122. If it is determined in step S122 that a position information request is transmitted (Yes in step S122), the control unit 40 proceeds to step S52, and if it is determined that a position information request is not transmitted (No in step S122), step S124. Proceed to

  When it is determined that the position confirmation process is not executed in step S120 (No in step S120), the control unit 40 determines whether an emergency earthquake bulletin has been received as step S50. When it is determined that the emergency earthquake bulletin has not been received in step S50 (No in step S50), the control unit 40 ends this process. When determining that the earthquake early warning has been received in Step 50 (Yes in Step S50), the control unit 40 transmits a location information request to the second mobile phone in Step S52. When the process of step S52 is executed, or when it is determined No in step S122, the control unit 40 determines whether to execute the pairing process as step S124. Specifically, the control unit 40 determines whether it is a process for executing the pairing process based on the process detected in Step S120 or Step S50. When it is determined that the pairing process is not executed in Step S124 (No in Step S124), the control unit 40 proceeds to Step S58. When it is determined that the pairing process is to be executed in step S124 (Yes in step S124), the control unit 40 proceeds to step S54.

  When it is determined Yes in step S124, the control unit 40 executes pairing processing with the second mobile phone as step S54. After executing the pairing process in step S54, the control unit 40 determines whether the pairing is successful in step S56. That is, the control unit 40 determines whether communication by the short-range communication has been established with the second mobile phone 10 that is the transmission destination of the position information request. If the control unit 40 determines in step S56 that the pairing has succeeded (Yes in step S56), that is, communication has been established, the process ends.
