1. An information processing apparatus comprising:
a processor configured to acquire position information of a communication device; and
a storage configured to store first map information and second map information, the first map information indicating a plurality of first partial areas that divide an area in which the communication device is movable, the second map information indicating a plurality of second partial areas that divide the area, each of the plurality of second partial areas being smaller than each of the plurality of first partial areas; wherein:
the processor is further configured to:
in a case in which the processor acquires position information a predetermined number of times of at least two or more, in a first partial area of the plurality of first partial areas, based on the first map information, determine that the communication device exists in the first partial area, and
in a case in which the processor acquires position information a predetermined number of times of at least two or more, in a second partial area of the plurality of second partial areas, based on the second map information, determine that the communication device exists in the second partial area.
