  So far, the basic configuration of the communication system 10 according to the present embodiment has been described. Hereinafter, an example of control in the communication system 10 when it is detected that the first mobile phone 1 is moving on a vehicle will be described with reference to FIGS. 5 to 7. FIG. 5 is a diagram illustrating an example of processing of the communication system 10 when it is detected that the first mobile phone 1 is moving on a vehicle. FIG. 6 is a diagram illustrating an example of a screen displayed by the second mobile phone 2 that has received the notification information. FIG. 7 is a diagram illustrating an example of a screen displayed by the second mobile phone 2 that has received the position information.

  As shown in FIG. 5, when the vehicle detection unit 120 detects that the first mobile phone 1 is moving as a vehicle (step S <b> 1), the first mobile phone 1 executes a positioning process in the positioning unit 110. (Step S2). The first mobile phone 1 determines whether the notification information should be transmitted to the second mobile phone 2. For example, the first mobile phone 1 determines that the notification information should be transmitted to the second mobile phone 2 when the measured position is not included in any area indicated by the area condition of the notification condition information 44. . Alternatively, the first mobile phone 1 may notify when the current position is not included in the time zone corresponding to the area, even if the measured position is included in any area indicated by the area condition of the notification condition information 44. It is determined that information should be transmitted to the second mobile phone 2. When it is determined that the notification information should be transmitted to the second mobile phone 2, the first mobile phone 1 transmits the notification information indicating that the vehicle is moving on the vehicle to the second mobile phone 2 (step S3). . The notification information includes, for example, the type of vehicle, the position information obtained in step S2, and the current time.

  The first mobile phone 1 changes the mode of the position transmission process when detecting that the vehicle is moving on the vehicle. The position transmission process is a process for causing the positioning unit 110 to perform positioning and transmitting the obtained position information to the second mobile phone 2. The mode change may be to periodically execute a position transmission process that has not been executed. The mode change may be to change the transmission interval at which the position transmission process is executed. By shortening the transmission interval, the guardian can grasp the situation of the guardian in detail. By increasing the transmission interval, power consumption can be suppressed and the operating time of the first mobile phone 1 can be extended. The first mobile phone 1 may transmit other information together when transmitting the position information in the position transmission process. Other information includes, for example, the current time, the remaining battery level, and the like. In this case, the mode change may be to increase or decrease the information transmitted to the second mobile phone 2.

  The first mobile phone 1 may be configured such that a guardian can arbitrarily set a mode before and after detecting that the first mobile phone 1 is moving on a vehicle. The first mobile phone 1 may be configured to change the mode change method according to the detected vehicle type. When the first mobile phone 1 receives a request transmitted from the second mobile phone 2 in response to the operation of the guardian, the mode changed when detecting that the vehicle is moving is changed to the original mode. It may be configured to return.

  When receiving the notification information from the first mobile phone 1, the second mobile phone 2 performs notification based on the notification information (step S4). For example, the second mobile phone 2 acquires map data corresponding to the position information included in the notification information, displays the screen 300 shown in FIG. 6 on the display unit 35, and outputs a notification sound from the speaker 32 or the like. The screen 300 has a message part 301 and a map part 302. The message unit 301 displays a message for notifying that the first mobile phone 1 is moving on a vehicle. The map unit 302 displays map data corresponding to the position information included in the notification information. In the example illustrated in FIG. 6, the message unit 301 displays a message “The first mobile phone is moving in a car”. In the example illustrated in FIG. 6, the map unit 302 displays map data 400 including the mark P1 corresponding to the position indicated by the position information included in the notification information.

  Thereafter, when the transmission interval elapses after the first mobile phone 1 transmits the notification information to the second mobile phone 2 in step S3, the positioning unit 110 performs a positioning process (step S5). The first mobile phone 1 transmits the position information obtained by the positioning process to the second mobile phone 2 (step S6).

  When the second mobile phone 2 receives the position information from the first mobile phone 1, it performs notification based on the position information (step S7). For example, the second mobile phone 2 acquires map data including the position information included in the notification information transmitted in step S3 and the respective positions indicated by the position information transmitted in step S6, as shown in FIG. The screen 300 is updated. In the example shown in FIG. 7, the display of the message part 301 on the screen 300 is left as it is, and the map data 401 is displayed on the map part 302. Map data 401 includes mark P1 corresponding to the position indicated by the position information included in the notification information and mark P2 corresponding to the position indicated by the position information transmitted in step S6. That is, the map data 401 indicates the current position (mark P2) and the movement locus (marks P1, P2) of the first mobile phone 1. Thereafter, the communication system 10 repeats Steps S5 to S7 at every transmission interval.

  Next, an example of a processing procedure for detecting that the first mobile phone 1 is moving on a vehicle will be described with reference to FIG. FIG. 8 is a flowchart showing an example of a processing procedure for detecting that the first mobile phone 1 is moving on a vehicle. The processing procedure shown in FIG. 8 is repeatedly executed when the position transmission processing mode is the initial mode.

  As shown in FIG. 8, the control unit 100 acquires the detection result of the vehicle detection unit 120 as step S101. In step S102, the control unit 100 determines whether the vehicle detection unit 120 has detected that the vehicle is moving based on the detection result acquired in step S101. If the control unit 100 determines in step S102 that it is not detected that the vehicle is moving (No), this control procedure is terminated. If the control unit 100 determines in step S102 that it is detected that the vehicle is moving (Yes), the control unit 100 proceeds to step S103.

  The control part 100 performs a positioning process by the positioning part 110 as step S103. Based on the notification condition information 44, the control unit 100 determines whether or not the notification information should be transmitted to the second mobile phone 2 in step S104.

  When it is determined that the notification information should not be transmitted to the second mobile phone 2 (No) in step S104, the control unit 100 ends this processing procedure. When the control unit 100 determines in step S104 that the notification information should be transmitted to the second mobile phone 2 (Yes), the control unit 100 proceeds to step S105.

  In step S105, the control unit 100 transmits notification information indicating that the first mobile phone 1 is moving as a vehicle to the second mobile phone 2. Then, in step S106, the control unit 100 changes the position transmission processing mode, and ends this processing procedure.

  Next, an example of a procedure of position transmission processing when the mode is changed will be described with reference to FIG. FIG. 9 is a flowchart illustrating an example of a processing procedure of the position transmission process when the mode is changed. The processing procedure shown in FIG. 9 is repeatedly executed after the position transmission processing mode is changed in step S106 shown in FIG.

  As shown in FIG. 9, the control unit 100 sets a transmission interval as step S201, and monitors the elapse of the transmission interval using a timer or the like. In step S202, the control unit 100 determines whether the transmission interval has elapsed. If the control unit 100 determines in step S202 that the transmission interval has not elapsed (No), the control unit 100 proceeds to step S205. If the control unit 100 determines in step S202 that the transmission interval has elapsed (Yes), the control unit 100 proceeds to step S203.

  The control part 100 performs a positioning process by the positioning part 110 as step S203. And the control part 100 transmits the positional infomation obtained by the positioning process to the 2nd mobile telephone 2 as step S204. Thereafter, the control unit 100 ends this processing procedure.

  In step S205, the control unit 100 determines whether a mode return request has occurred. The mode return request is a request for returning the position transmission processing mode to the initial mode. The mode return request is generated, for example, when an instruction based on a predetermined operation of the guardian on the second mobile phone 2 is transmitted from the second mobile phone 2 to the first mobile phone 1. After changing the position transmission processing mode, first mobile phone 1 periodically determines whether or not a situation in which notification information should be transmitted continues based on notification condition information 44 and transmits the notification information. A mode return request may be generated when it is determined that the power situation has not continued.

  If the control unit 100 determines in step S205 that no mode return request has been generated (No), the control unit 100 returns to step S202 and executes the subsequent steps. If the control unit 100 determines in step S205 that a mode return request has occurred (Yes), the control unit 100 proceeds to step S206. In step S206, the control unit 100 returns the position transmission processing mode to the initial mode, and ends this processing procedure.
