In step S820, the communication terminal 100 may adjust the degree of detail of the location-based information according to the resolution set in the external terminal. For example, it is assumed that the resolution is set from the first to the tenth class for each terminal and sets detailed location-based information from the first to the tenth class. On the contrary, detailed location-based information may be set from the tenth grade to the first grade. In addition, the resolution level may be changed by user manipulation or may be changed at any time according to the location of the external terminal. For example, the position of the communication terminal 100 and the external terminal is compared
