<p><P>PROBLEM TO BE SOLVED: To share information among a plurality of radio communication terminals existing in or entering/leaving a specific area at the same or different times in an environment without network infrastructure. <P>SOLUTION: A radio communication terminal having a radio communication function detects an area corresponding to the present position of the radio communication terminal. Area information obtained by the area detection is added to storage information stored by the radio communication terminal and wirelessly transmitted to other radio communication terminals. Storage information received from the other radio communication terminal by the radio communication function is retained by the radio communication terminal while the radio communication terminal is in the area shown in the area information added to the storage information, and the storage information retained by the radio communication terminal is discarded when the radio communication terminal leaves the area shown in the added area information. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
