A radio communication terminal receives position information showing a position of another radio communication terminal. The radio communication terminal obtains, from the position information, a terminal ID of the radio communication terminal, and a beacon ID for identifying the predetermined location nearest to the radio communication terminal. The radio communication terminal accepts the predetermined location designated by a user. The radio communication terminal determines as a communication partner terminal, the other radio communication terminal that is nearest to the accepted predetermined location based on the terminal ID and the beacon ID. The radio communication terminal performs communication with the determined communication partner terminal.
