A mobile communication terminal includes a location information database storing location data and map data for each of the radio cell stations. When receiving a data request including an identification of a second mobile terminal from a first mobile terminal through a first radio cell station, the database is searched for first location data of the first radio cell station, second location data of a second radio cell station forming a micro cell in which the second mobile terminal is located, and map data for at least one of the first and second radio cell stations. Then the first and second location data and retrieved map data are transferred to the first mobile terminal through the first radio cell station and thereby a map and two locations corresponding to the first and second mobile terminals are displayed on screen based on the retrieved map data and the first and second location data.
