Abstract

An object of the present invention is to measure a current position at appropriate timing and perform a predetermined process at a predetermined position. In a case where it is detected that a portable terminal (100) has entered a region in which the portable terminal (100) can make a radio communication with an access point (50), current positional information of the portable terminal (100) is obtained, and in a case where the portable terminal (100) is at a predetermined position, a predetermined process is performed.

Claims

1. A portable terminal which performs a process in accordance with a predetermined range in a case where it is specified that the portable terminal is within the predetermined range,

said portable terminal comprising:

a detection section configured to detect the portable terminal having entered a radio communication region of a device registered beforehand, based on the detection section having received a signal from the device;

a positional information obtaining section configured to obtain current positional information of the portable terminal in a case where the detection section detects the portable terminal having entered the radio communication region; and

a position specifying section configured to determine whether the portable terminal is within the predetermined range based on the current positional information obtained by the positional information obtaining section.

2. The portable terminal as set forth in claim 1, further comprising a storage section which stores therein identification information for the device,

the detection section deletes the identification information from the storage section, in a case where (i) the detection section detects the portable terminal having entered the radio communication region of the device and (ii) the position specifying section determines that the portable terminal is not within the predetermined range.

3. The portable terminal as set forth in claim 1 or 2, wherein

the detection section detects the portable terminal having left the radio communication region, based on the detection section having no longer received any signal from the device, and

in a case where the portable terminal has left the radio communication region, the position specifying section obtains current positional information of the portable terminal and then determines, based on the current positional information, whether the portable terminal is present within the predetermined range or not.

4. The portable terminal as set forth in claim 3, wherein the position specifying section obtains the current positional information of the portable terminal, (i) in a case where a given length of time has elapsed since the portable terminal left the radio communication region or (ii) in a case where the portable terminal is moving after the portable terminal left the radio communication region.

6. A control program for causing a computer to function as a portable terminal as set forth in claim 1, the control program causing the computer to function as the detection section and the position specifying section.

5. A method of controlling a portable terminal, the method causing the portable terminal to perform a process in accordance with a predetermined range, the portable terminal being specified that the portable terminal is within the predetermined range,

said method comprising the steps of:

(i) detecting the portable terminal having entered a radio communication region of a device registered beforehand, based on a reception of a signal from the device;

(ii) obtaining current positional information of the portable terminal in a case where the portable terminal having entered the radio communication region is detected in the step (i); and

(iii) specifying that the portable terminal is within the predetermined range in a case where a position indicated by the current positional information obtained in the step (ii) is within the predetermined range.
