Information processing device, information processing system, computer-readable storage medium, and information processing method

A non-transitory computer-readable storage medium recording a program, the program configured to, when installed in a computer, execute a predetermined method comprising:

• acquiring position information of a communication device;
• in a case of acquiring position information at least two or more times, in a first partial area of a plurality of first partial areas, determining that the communication device exists in the first partial area, based on first map information indicating the plurality of first partial areas that divide an area in which the communication device is movable;
• and
• in a case of acquiring position information at least two or more times, in a second partial area of a plurality of second partial areas, based on second map information indicating the plurality of second partial areas that divide the area, determining that the communication device exists in the second partial area, wherein each of the plurality of second partial areas is smaller than each of the plurality of first partial areas.
