FIG. 8 is a diagram illustrating an example of a screen displayed on the display unit of the first mobile phone.

  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 phones 50a and 50b in step S2, and the first mobile phone 10 The second mobile phones 50a and 50b receive the current position request command output from the telephone 10. That is, the first mobile phone 10 outputs position information requests of the plurality of second mobile phones 50a and 50b associated as step S2, and the second mobile phone 50 receives the position information requests. The first mobile phone 10 can transmit the command to the second mobile phones 50a and 50b by including the command indicating the position information request in the electronic 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 phones 50a and 50b 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 phones 50a and 50b.

  If the second mobile phone 50a, 50b 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, the pairing process is performed as step S3. That is, processing for establishing communication using the short-range communication unit 66 is started. The communication unit 100 executes pairing processing in both the second mobile phone 50a and the second mobile phone 50b in step S3, and performs communication by short-range communication between the second mobile phone 50a and the second mobile phone 50b. If established, terminal information is output from the second mobile phone 50b to the second mobile phone 50a by short-range communication as step S4. Here, the terminal information is information that can identify the second mobile phone 50b. As the terminal information, a telephone number, a terminal number, and a mail address can be used.

  When the second mobile phone 50a acquires the terminal information of the second mobile phone 50b by short-range communication in step S4, the communication unit 100 receives the GPS signal in step S5, and receives the second mobile phone 50a, that is, the own mobile device. Get location information. The second mobile phone 50a 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 50a obtains its own location information in step S5, the communication unit 100 returns the location information of the second mobile phone 50a from the second mobile phone 50a to the first mobile phone 10 in step S6. . That is, the second mobile phone 50a transmits the position information acquired in step S5 to the first mobile phone 10. The second mobile phone 50a transmits the location information of the second mobile phone 50b to the first mobile phone 50 together with the location information of its own device. The communication unit 100 of the present embodiment uses the same position as the position information of its own device as the position information of the second mobile phone 50b. The second mobile phone 50a of the present embodiment sends an e-mail including the location information of the own device and the location information of the second mobile phone 50b to the first mobile phone 50. The first mobile phone 10 receives the position information of the second mobile phone 50a and the second mobile phone 50b transmitted from the second mobile phone 50a. The first mobile phone 10 according to the present embodiment receives the position information of the second mobile phone 50a and the second mobile phone 50b by receiving the electronic mail transmitted from the second mobile phone 50a. The communication unit 100 outputs only the terminal information in step S4, but the second mobile phone 50b may detect the position information and transmit the detected position information together with the terminal information.

  Next, a process executed by the first mobile phone 10 that has acquired the position information of the second mobile phone 50a and the second mobile phone 50b transmitted from the second mobile phone 50a will be described with reference to FIG. FIG. 8 is a diagram illustrating an example of a screen displayed on the display unit 26 of the first mobile phone. When the first mobile phone 10 acquires the position information of the second mobile phones 50a and 50b, the first mobile phone 10 displays a map image 101 indicating the positions of the second mobile phones 50a and 50b 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 phones 50a and 50b. The map image 101 includes marks 102 and 104. The mark 102 indicates the position of the second mobile phone 50a. The mark 104 indicates the position of the second mobile phone 50b.

  Next, another example of processing executed by the communication unit 100 will be described with reference to FIG. FIG. 9 is an example of control executed when pairing of short-range communication fails between the first mobile phone 10, the second mobile phone 50a, and the second mobile phone 50b.

  As shown in FIG. 9, in the communication unit 100, the first mobile phone 10 receives the earthquake early warning as step S11. When the first mobile phone 10 receives the earthquake early warning in step S11, the communication unit 100 outputs a current position request command from the first mobile phone 10 to the second mobile phones 50a and 50b in step S12, and the first mobile phone 10 The second mobile phones 50a and 50b receive the current position request command output from the telephone 10.

  If the second mobile phone 50a, 50b analyzes the e-mail including the location information request received in step S12 and determines that the location information request command is due to the earthquake early warning, the pairing process is performed as step S13. That is, the process for establishing communication using the short-range communication unit 66 is started, and the pairing process fails. That is, the communication unit 100 fails in the pairing process executed in both the second mobile phone 50a and the second mobile phone 50b in step S13, and the short distance between the second mobile phone 50a and the second mobile phone 50b. Detects that communication is not established.

  When the pairing failure is detected in step S13, the second mobile phone 50a receives the GPS signal and acquires the position information of the second mobile phone 50a, that is, its own device, in step S14. The second mobile phone 50a 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 50a acquires the position information of the own device in step S14, the communication unit 100 returns the position information of the second mobile phone 50a from the second mobile phone 50a to the first mobile phone 10 in step S15. . That is, the second mobile phone 50a transmits the position information acquired in step S14 to the first mobile phone 50. The second mobile phone 50a of 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 50a transmitted from the second mobile phone 50a.

  Furthermore, the communication unit 100 receives a GPS signal as step S16, and acquires the position information of the second mobile phone 50b, that is, its own device. The second mobile phone 50b 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 50b acquires the position information of the own device in step S16, the communication unit 100 returns the position information of the second mobile phone 50b from the second mobile phone 50b to the first mobile phone 10 in step S17. . That is, the second mobile phone 50a transmits the position information acquired in step S14 to the first mobile phone 10 as the process of step S17. The second mobile phone 50a of 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 50b transmitted from the second mobile phone 50b. Note that the order of steps S14 and S15 in FIG. 9 and steps S16 and S17 may be reversed.

  Based on the position information output from each of the second mobile phones 50a and 50b, the first mobile phone 10 displays a map image including the positions of the second mobile phones 50a and 50b as in FIG. . It is preferable that the first mobile phone 10 displays one map including both the positions of the second mobile phones 50a and 50b.

  Next, processing executed by the second mobile phone 50 (second mobile phones 50a and 50b) 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 receiving the position information request at step S40, the control unit 70 executes a pairing process with another second mobile phone 50 at step S41. After executing the pairing process in step S41, the control unit 70 determines whether the pairing is successful in step S42. In other words, the control unit 70 determines whether communication by short-range communication has been established with another second mobile phone 50 associated with the same first mobile phone 10.

  When determining that pairing has failed (No in step S42), that is, communication has not been established in step S42, the control unit 70 receives a GPS signal and identifies the position in step S43. 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 S43, the control unit 70 outputs the position information to the first mobile phone 10 in step S44, 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.

  If it is determined in step S42 that the pairing has succeeded (Yes in step S42), that is, communication has been established, the control unit 70 determines whether there is a transmission setting for position information in step S45. Here, the position information transmission setting is a setting for transmitting the detected position information to the first mobile phone 10 when the pairing is successful.

  When it is determined in step S45 that there is no transmission setting (No in step S45), the control unit 70 transmits information of the own device to the pair partner as step S46. In other words, when the location information transmission setting is not made, like the above-described second mobile phone 50b of FIG. 7, the other second mobile phone 50 that establishes communication by pairing its own terminal information, FIG. 7 transmits to the second mobile phone 50a. When the control unit 70 transmits the information of the own device in step S46, the process ends. As described above, when there is no transmission setting for transmitting the position information to the first mobile phone 10 when the pairing is successful, the control unit 70 sends the identification information of the own device to the second mobile phone 50 of the pair partner and ends the process. To do.

  If it is determined in step S45 that there is a transmission setting (Yes in step S45), the control unit 70 receives a GPS signal and identifies the position in step S47. 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. After identifying the position in step S47, the control unit 70 acquires the pair partner information in step S48. Specifically, the short-range communication unit 66 receives the identification information of the second mobile phone 50 of the pair partner that is output from the second mobile phone 50 of the pair partner in the short-range communication. The order of the process of step S47 and the process of step S48 may be reversed or simultaneous.

  After acquiring the position information of the own device and the information of the pair partner in steps S47 and S48, the control unit 70 outputs the position information of the own device and the information of the pair partner to the first mobile phone 10 in step S49. The process ends. That is, the control unit 70 outputs the acquired position information of the own device and the information of the pair partner to the specific first mobile phone 10 associated with the communication unit 58. The output method of the position information and pair partner information is not particularly limited, but is preferably output as an e-mail as described above. As described above, when the transmission setting of the position information is set, the control unit 70, like the second mobile phone 50a of FIG. 7 described above, is another second mobile phone that has been successfully paired with the detected position information. 50 information is transmitted to the first mobile phone 10.

  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. When determining that the earthquake early warning has been received in Step 50 (Yes in Step S50), the control unit 40 transmits a current position request command to the target second mobile phone in Step S52. That is, the control unit 40 transmits a current position request command to a plurality of second mobile phones associated as step S52. For example, the control unit 40 transmits an e-mail including a current position request command to the plurality of second mobile phones through the communication unit 28.

  When the current position request command is transmitted to the target second mobile phone in step S52, the control unit 40 receives the position information transmitted from the second mobile phone in step S58. That is, the control unit 40 acquires the position information of the second mobile phone associated 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 information 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 34 or may be acquired from an external communication device such as the server 6 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 determine whether there exists information of a pair other party in position information as step S65. For example, the control unit 40 includes the terminal information of the other second mobile phone 50 successfully paired by the second mobile phone 50 in the e-mail of the location information of the second mobile phone 50 received in step S58. Judge whether or not. When it is determined in step S65 that there is pair partner information (Yes in step S65), the control unit 40 adds a display of the position of the pair partner on the map data as step S66. Specifically, the control unit 40 adds a display of the position of the pair partner near the position of the second mobile phone that acquired the position information. After adding the position information display in step S66, the control unit 40 proceeds to step S68.

  When it is determined in step S65 that there is no pair partner information (No in step S65), or when the process of step S66 is executed, the control unit 40 displays the map on the display unit 26 in step S68, which is the display 12 in this embodiment. Is displayed. Control part 40 ends this processing, when a map is displayed on a display part at Step S68.

  As described above, when the first mobile phone 10 receives the earthquake early warning, the communication system 1 causes the second mobile phone 50 to output a position information request from the first mobile phone 10 to the second mobile phone 50. The process of acquiring the position of is executed. Thereby, the communication system 1 is the first mobile phone in which the guardian possesses the position of the second mobile phone 50 possessed by each of a plurality of subjects to be protected when the emergency earthquake bulletin has been filed, that is, when the urgency is high. The telephone 10 can be notified.

  When the location information request is output from the first mobile phone 10 due to the earthquake early warning, the communication system 1 performs pairing between the corresponding second mobile phones 50, and the pairing is successful. When communication by near field communication is established between a plurality of second mobile phones 50, one second mobile phone 50 also transmits information of other second mobile phones 50 that have been paired successfully . The other second mobile phone 50 that has been successfully paired transmits its own information to the first mobile phone 10 via the one second mobile phone 50 and does not transmit the position information via the communication unit 58. . That is, in the communication system 1, when a plurality of second mobile phones 50 corresponding to the first mobile phone 10 are nearby when the earthquake early warning is received, one representative second mobile phone 50 is combined into a plurality of second mobile phones 50. 2 Transmits location information of the mobile phone 50.

  As a result, when the persons holding the plurality of second mobile phones 50 are together or within a range that can be regarded as being together, the plurality of second mobile phones 50 can individually transmit and receive position information via the network. This can be suppressed. Thereby, the position information of the plurality of second mobile phones 50 can be transmitted and received by transmitting and receiving information between one first mobile phone 10 and one second mobile phone 50. The first mobile phone 10 acquires the position information of the plurality of second mobile phones 50 by receiving one piece of information, so that the positions of the plurality of second mobile phones 50 in the vicinity can be simultaneously displayed on one map. Can be displayed. Thereby, it is not necessary to switch the map in which the position information of the plurality of second mobile phones 50 is displayed separately, or to perform the process of merging individually acquired position information, and the operability can be improved. In addition, since the number of communication lines through the network can be reduced by collectively transmitting the position information to the first mobile phone 10 by one second mobile phone 50, the load on the network is also reduced. be able to.

  When the second mobile phone 50 fails to pair, the communication system 1 and the first mobile phone 10 individually acquire the location information of the second mobile phone 50 and display a map including the location information of the second mobile phone 50. Display individually. Thereby, the communication system 1 and the first mobile phone 10 can display the positions of the second mobile phones 50 on the map even when the second mobile phone 50 is separated. Thereby, the 1st mobile telephone 10 can show the position of the several protection subject who is the user of the 2nd mobile telephone 50 with respect to the guardian who is a user.

  Here, although the communication system 1 of the above-described embodiment has been described as the case where the first mobile phone 10 receives the earthquake early warning, the pairing process is performed. However, the electronic device including emergency information other than the emergency earthquake early warning described above is used. Similarly, mail may be paired between the second mobile phones 50. 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.

  In the communication system 1 of the above embodiment, when pairing is successful, only the terminal information of the other second mobile phone 50 is transmitted to the second mobile phone (using the communication unit 58 on the first mobile phone) by infrared communication. However, the present invention is not limited to this. The other second mobile phone 50 may transmit the position information of the own device acquired by the GPS communication unit 64 in addition to the terminal information. In this case, the second mobile phone 50 transmits the terminal information and the position information of the other second mobile phone to the first mobile phone using the communication unit 58. Thereby, the first mobile phone 10 can acquire the position information of the other second mobile phone 50 with higher accuracy.

  The communication system 1 can determine the presence / absence of the transmission setting of the position information determined in step S45 under various conditions. For example, the communication system 1 may set the presence / absence of transmission setting of position information in advance and store it in the storage unit 68. Thereby, when the pairing is successful, the plurality of second mobile phones 50 can determine the presence / absence of the transmission setting of the position information based on the setting, and execute a process based on the determination.

  As another method, the communication system 1 sets the second mobile phone 50, which is a master for the pairing process, when the short-range communication using the short-range communication unit 66 is established, that is, the position information transmission setting, The second mobile phone 50 that has become can be set to have no transmission setting for position information. As a result, the communication system 1 positions one second mobile phone 50 among the plurality of second mobile phones 50 even when there are a large number of associated second mobile phones, without setting ranking or the like. It can be set as the 2nd mobile telephone 50 with the transmission setting of information.

  When the second mobile phone 50 of the communication system 1 of the above embodiment receives the position information request (current position request command), the pairing process is performed, but the present invention is not limited to this. 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 another second mobile phone as Step S72. After executing the pairing process in step S72, 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. 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. 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.

  If it is determined in step S74 that the pairing has succeeded (Yes in step S74), that is, communication has been established, the control unit 70 determines whether there is a transmission setting for position information in step S80. When determining that there is no transmission setting in step S80 (No in step S80), the control unit 70 transmits the information of the own device to the pair partner in step S82, and ends this processing.

  If it is determined in step S80 that there is a transmission setting (Yes in step S80), the control unit 70 receives a GPS signal and identifies the position in step S84. After identifying the position in step S84, the control unit 70 acquires information on the pair partner in step S86.

  After acquiring the position information of the own device and the information of the pair partner in steps S84 and S86, the control unit 70 outputs the position information of the own device and the information of the pair partner to the first mobile phone 10 in step S88. End the process.

  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 the position information from the second mobile phone 50 to the first mobile phone 10 is executed, the pairing process may be executed before executing the position information transmission process. .

  Here, in the communication system 1, when the user operates the operation unit 24 of the first mobile phone 10 and acquires the position information of the second mobile phone 50, the communication system 1 performs the pairing process regardless of the result of the pairing process. It is preferable to transmit the position information of the second mobile phone 50 to the first mobile phone 10 without executing it. 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. Further, the communication system 1 can quickly transmit the respective positions of the second mobile phone 50 to the first mobile phone by omitting the pairing process.

  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 second mobile phone 50 may switch whether or not to perform pairing with another second mobile phone 50 in response to a trigger for transmitting position information to the first mobile phone 10. When the communication system 1 executes the process of transmitting the position information from the second mobile phone 50 to the first mobile phone 10, the communication system 1 executes a more appropriate process by switching the process to be executed according to a trigger for starting the process. can do.

  The communication system 1 has performed pairing between the second mobile phone 50 and another second mobile phone, and further, paired by short-range communication between the second mobile phone 50 and the first mobile phone 10. You may perform a ring. In this case, if the pairing with the first mobile phone 10 is successful, the second mobile phone 50 of the communication system 1 does not transmit its own location information. As a result, when the second mobile phone 50 is in the vicinity of the first mobile phone 10 and there is a high possibility that the position can be grasped, the position from the second mobile phone 50 to the first mobile phone 10 via the communication unit 58 is high. It can suppress that information is transmitted. Thereby, it can suppress that the map which shows the position of the 2nd mobile telephone 50 which can grasp | ascertain the position on the 1st mobile telephone 10 can be suppressed, and operativity can be improved.

  Further, in the communication system 1 of the above embodiment, when the position information of the second mobile phone is output, only the position information of the second mobile phone is displayed on the map, but the position of the first mobile phone 10 is also adjusted. It is also preferable to display on a map.

  A process executed by the first mobile phone 10 will be described with reference to FIG. FIG. 13 is a flowchart illustrating an example of processing executed by the first mobile phone.

That is, the control unit 40 acquires the position information of the second mobile phone in step S142. When the position information is received in step S142, the control unit 40 receives a GPS signal in step S144, and specifies the position of the first mobile phone 10 that is its own terminal.

  After specifying the position in step S144, that is, acquiring the position information, the control unit 40 specifies the range and scale of the map based on the position of the second mobile phone 50 and the position of the first mobile phone 10 in step S146. . Specifically, a range in which both the position of the first mobile phone 10 and the position of the second mobile phone 50 are included 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 both the position of the first mobile phone 10 and the position of the second mobile phone 50 are located at a certain distance or more away from the edge of the screen, that is, the end of the range. Further, 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 specifying the map range and scale in step S146, the control unit 40 extracts map data to be used in step S148. 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 34 or may be acquired from an external communication device such as the server 6 by communication using the communication unit 28.

  After extracting the map data to be used in step S148, the control unit 40 adds the display of the positions of the second mobile phone 50 and the first mobile phone 10, that is, the display of the mark, on the map data as step S150. When the display of the position is added in step S150, the control unit 40 determines whether there is pair partner information in the position information as step S151. When it is determined in step S151 that there is pair partner information (Yes in step S151), the control unit 40 adds a display of the position of the pair partner on the map data as step S152. Specifically, the control unit 40 adds a display of the position of the pair partner near the position of the second mobile phone that acquired the position information. After adding the position information display in step S152, the control unit 40 proceeds to step S153.

  When it is determined in step S151 that there is no pair partner information (No in step S151), or when the process of step S152 is executed, the control unit 40 displays the map on the display unit 26 as step S153, which is the display 12 in this embodiment. Is displayed.

  If the map is displayed in step S153, the control unit 40 determines whether to display the map for the second mobile phone in step S154. If the set condition is satisfied, the control unit 40 determines to display a map for the second mobile phone. Here, the map for the second mobile phone 50 is an enlarged map showing the position of the second mobile phone 50 as shown in FIGS. 15 and 16.

  When it is determined that the map is not displayed in Step S154 (No in Step S154), the control unit 40 proceeds to Step S164. When it is determined that the map is displayed in step S154 (Yes in step S154), the control unit 40 specifies the map range and scale based on the position of the second mobile phone 50 in step S156. 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 may be a range having a preset size. The scale of the map may be a preset scale.

  After identifying the map range and scale in step S156, the control unit 40 extracts map data to be used in step S158. That is, the control unit 40 extracts map image data corresponding to the range and scale to be used.

  After extracting the map data to be used in step S158, 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 S160. When the display of the position is added in step S160, the control unit 40 determines whether there is pair partner information in the position information as step S161. If it is determined in step S161 that there is pair partner information (Yes in step S161), the control unit 40 adds a display of the pair partner position on the map data in step S162. Specifically, the control unit 40 adds a display of the position of the pair partner near the position of the second mobile phone that acquired the position information. After adding the position information in step S162, the control unit 40 proceeds to step S163.

  When it is determined in step S161 that there is no information on the pair partner (No in step S161), or when the process of step S162 is executed, the control unit 40 performs step S163 on the display unit 26, which is the display 12 in this embodiment. 2 Display a map for mobile phones. The map image created in step S160 may be displayed on a part of the display 12 or may be displayed on the whole.

  If the process of step S163 is performed or if it is determined No in step S154, the control unit 40 determines whether the display is terminated as step S164. If the control unit 40 determines that the display is not finished in step S164 (No in step 164), the control unit 40 proceeds to step S154 and repeats the above processing. When it is determined in step S164 that the display is ended (Yes in step S164), the control unit 40 ends the process.
