摘要

Location data of communication devices (other communication devices) each of which is located in the specification location (an area which a user desires) and each of which is capable of offering information (of a congestion situation, a road surface situation and the like) therein is transferred to a communication device requesting data in the specification location. Since the communication device requesting data can select the communication devices among the other communication devices each located in the specification location by referring to the location data transferred thereto from the other communication devices, it can obtain the data in the specification location from the selected communication devices. Since the communication device requesting data can arbitrarily select the communication devices among the other communication devices each located in the specification location, it is possible to grasp a time when the data in the specification location is obtained.
