PROBLEM TO BE SOLVED: To easily obtain continued map information for an intended wide range with a simple operation by use of two or more portable communication terminals. SOLUTION: Since the same map screen having vertically and horizontally divided grids are displayed by two or more cellular phones (portable communication terminals) 1-1 to -N which form one group, and each of the cellular phones 1-1 to -N obtains a different map range from a map server 20 by designating it by the grid position, the map is never cut in a dividing boundary line. Since one main cellular phone. 1-1 acquires a commonly intended map screen and transmits its URL to each of the other slave cellular phones 1-2 to -N by e-mail, the same map can be surely and easily acquired. Further, when each of the slave cellular phones 1-2 to -N designates any one of vertical, lateral and oblique parts from the same map screen and obtains it from the map server, a continued enlarged map can be obtained.
