The controller 290 determines whether the location information corresponding to the repeater identification information (gap filler ID) extracted in step S505 exists in the location information DB for each repeater identification information (gap filler ID) (S509).

If the determination result exists, the location information corresponding to the extracted relay identification information (gap filler ID) is extracted from the location information DB for each repeater identification information (gap filler ID) (S517), and the process returns to step S413 of FIG. 4.

If the location information corresponding to the extracted repeater identification information (gap filler ID) is not present in the location information DB for each repeater identification information (gap filler ID), the extracted repeater identification information (gap filler ID) is determined. It is determined whether an additional request signal of the location information arbitrarily determined by the user is input (S511).

As a result of the determination, when the additional request signal is input, it is determined whether the location information is input through the input unit 220 from the user (S513). As a result of the determination, when the location information is input, the controller 290 matches and stores the input location information with the repeater identification information (gap filler ID) extracted in the step S505 (S515).
