In such a state, the mobile terminals PS1 to PSm and the assist server SVa operate as follows. FIG. 6 is a flowchart showing the processing procedure and processing contents.
The portable terminals PS1 to PSm periodically receive GPS signals transmitted from a plurality of GPS satellites in step S11 under the control of the positioning control unit 111, and execute positioning processing in step S2. In this positioning process, a predetermined distance calculation is performed based on the plurality of received GPS signals, thereby obtaining positioning information representing the current position of the terminal in terms of latitude and longitude.

  Note that there are generally errors and fluctuations in the GPS positioning results. Therefore, the base station ID transmitted from the base stations BS1 to BSn is used together, and the positioning information based on the GPS signal is validated when the same base station ID is continuously received N (preset number) times. You may do it. In addition, referring to HDOP, which is information representing the accuracy of positioning, when the HDOP is below a threshold value, or by monitoring the movement of the mobile terminal (such as walking vibration) with an acceleration sensor provided in the mobile terminal, the user is walking. In the case where the positioning result by GPS is changing despite not being present, the positioning result by GPS at this time is estimated not to be reliable and is not adopted, or the threshold value N Should be increased.

  Furthermore, when the area is indoors, the GPS signal cannot be received and the positioning information based on the GPS signal cannot be calculated. In such a case, one or more base stations are installed in the danger area, and the position of the mobile terminal is estimated by detecting a difference in received electric field strength from these base stations. In this way, the current position of the mobile terminal can be measured even in an area where it is difficult to receive GPS signals.

  The positioning control unit 111 of the portable terminals PS1 to PSm generates the latitude / longitude information indicating the current position of the portable terminal calculated in step S12 and the positioning information including the terminal ID or telephone number of the own terminal in step S13, The positioning information is transmitted to the assist server SVa.

Switch to. By this mode switching, even if the silent mode is set, the silent mode is temporarily canceled. In step S22, a sound is generated from the sounder or the speaker, and thereafter the sound is continuously generated.

  In this state, it is assumed that the user presses an arbitrary key on the portable terminal PS1. When the portable terminal PS1 detects this key operation in step S23 under the control of the danger mode operation control unit 113, the portable terminal PS1 is based on the telephone number of the emergency call destination portable terminal stored in the storage unit 16 in step S24. The emergency report information is transmitted by transmitting to the mobile terminal (for example, the mobile terminal PSm possessed by the security guard) of the emergency report destination. At this time, a support request message such as “A user who has entered the danger area E1-2 cannot move. Please respond immediately” is inserted in the emergency alert information. At the same time, the URL (Uniform Resource Locator) of the assist server SVa is pasted on the message.

  Upon receiving the emergency alert information transmitted from the emergency alert source mobile terminal in step S25, the emergency alert destination mobile terminal PSm generates an emergency alert sound and receives the above-mentioned reception in step S26. The text message included in the emergency alert information is displayed on the display. Therefore, the guard who possesses the portable terminal PSm that is the emergency report destination can grasp the danger area where the emergency report has been made based on the displayed text message and can rush to the site.
