Abstract

Communications is executed between users through wireless terminals thereof without fear of being located by each other. On terminal 1 x , area 4 in which wireless communication is enabled with terminal 1 x is divided into proximity area 6 and external area 7 and the radius (distance between boundary 5 and terminal 1 x ) is temporally varied by random number. A control block of terminal 1 x detects terminals located in side the communicable area 4 and in the communication enabled state and processes the other terminals located inside proximity area 6 as out-of-service-area among the detected other terminals, not displaying the users of these other terminals located inside proximity area 6 onto display screen 2 x . The control block processes only other terminals located inside external area 7 as in-service area and displays the users of these other terminals onto display screen 2 x.
