摘要： A portable terminal includes a wireless public network communication portion for performing communication via a wireless public network, a short distance wireless communication portion for performing direct wireless communication with a terminal that exists within a short distance area, a communication history memory portion for storing a history of communication performed by using the wireless public network communication portion and a control portion for controlling each portion. The control portion searches other portable terminals that exist within the short distance area by using the short distance wireless communication portion, refers the communication history memory portion of each other with a found portable terminal, and informs a user of approach of the other end by using information means if there is a communication history with the other end exists in the communication history memory portion of each end.
