Can be used. On the other hand, if the mobile phone 1 is in the hands of a third party due to theft or loss, the third party has an action range different from that of the user. Then, the fraud prevention operation set according to the distance is executed, and a third party cannot use the mobile phone 1. In particular, if the alarm sound output cannot be stopped, the alarm sound will continue to sound even if a third party tries to use it illegally. Use can be prevented.

  The location information storage unit 23 of the server device 2 stores the location information of the mobile phone 1 together with the time information. By browsing this information, the unauthorized use that currently holds the mobile phone 1 is performed. Then, it becomes possible to easily track the position of the mobile phone 1 by a person who seems to be. In particular, when the unauthorized use prevention operation is activated so that the power supply cannot be turned off, the current position information of the mobile phone 1 is always registered, and it is possible to easily track the person who is thought to be illegally used. It can be carried out.

  Furthermore, since the user can freely set the above-described unauthorized use prevention operation and the operated distance value, it can be set according to the behavior at that time, and the convenience is improved. Can do.

  Here, the case where the position information acquired from the GPS system is used as the current position information of the mobile phone 1 has been described above. However, the present invention is not limited to this, and the position information to be registered for the base station unique to the mobile phone is used. It may be used. That is, the location registration information of the mobile phone received by the base station may be collected by the server device 2 and such information may be acquired as the current location information of each mobile phone 1. Therefore, the above-described system can be configured even for a mobile phone having no GPS function.

  Furthermore, although the case where the server apparatus 2 calculates the distance information and notifies it to the mobile phone 1 is illustrated above, the present invention is not limited to this, and the distance information may be calculated within the mobile phone 1. That is, the mobile phone 1 stores reference position information, a function of detecting the current position, and a function of calculating distance information based on the detected current position information and the stored reference position information. Can be operated in the same manner as described above. This eliminates the need for data communication with the server device 2.

  In addition, the said mobile phone 1 can also be utilized for the mobile phone for children, for example. For example, a security effect can be obtained by setting an alarm to be generated when it is detected that the mobile phone has moved beyond the distance between home and school.
