The owner of the mobile terminal device 4 can view the provided information by pressing the dedicated button 43. This time, it is possible to provide useful discount information and the like in the shopping street where the base station 1b is located.

According to this embodiment, the portable terminal device 4
Detects the base station located closest to the location of the
Since the provided information determined according to the detected base station is provided to the mobile terminal device 4 by e-mail, the information can be passively provided according to the moving position of the mobile terminal device 4. In addition, useful information according to the location of the base station can be provided.

Further, the mail server device 3 may determine the content of the provided information according to a predetermined content change pattern of the provided information, and the information may be provided by e-mail. For example, a table that associates the date and time with the content of the provided information is stored in the DB 31, the content of the provided information corresponding to the date and time is determined, and the information of the determined content is provided by the e-mail by the communication control unit 32. I do. According to this, the information provider can provide various information according to the time and time zone as desired by the provider.

In addition, the e-mail from the old base station can be automatically deleted with the change of the base station. First, in step S800 of FIG. 8, the information processing unit 20 determines that the base station has been changed (Yes).
To step S810, otherwise (N
In o), the operation is performed as described above.

In step S810, the information processing section 20
Transmits to the information processing section 30 a transmission instruction of a control signal for deleting the mail and the portable terminal device ID. In response, the information processing unit 30 controls the communication control unit 32 to transmit a mail erasure control signal. When the CPU 45 receives the control signal via the transmission / reception unit 48 of the mobile terminal device 4, the CPU 45 deletes only the information providing e-mail stored in the mail memory 47. It should be noted that it is possible to discriminate an information-providing e-mail from other e-mails based on e-mail header information or the like, and delete only necessary e-mails.

As described above, the control signal for detecting that the closest base station has been changed and for deleting all information-providing e-mails transmitted from the base station before the base station change is transmitted to the portable terminal device 4. Since the transmission is performed, the portable terminal device 4 can automatically delete the e-mail for information provision from the old base station other than the new base station in response to the transmission.

The location management server device 2 and the mail server device 3 in the embodiment of the present invention are realized by a computer system, and their functions are realized by a program stored in a recording medium such as an HD in which a program created in advance is recorded. , Can be realized by execution by the CPU.

Various modifications and changes can be made to the embodiment of the present invention described above without departing from the spirit of the present invention. The server device 3 may be a single computer system, or a notification sound may not be emitted when an electronic mail arrives.

As described above, according to the present invention, the base station located closest to the location of the portable terminal device is detected, and the provision is made according to the detected base station. Since information is provided to the mobile terminal device by e-mail, information can be passively given according to the moving position of the mobile terminal device, and useful information is provided according to the location of the base station. The effect is obtained.
