To efficiently obtain and register the position of a base station in a database. A map or a drawing, such as a plan of a building, is read and displayed on display unit ( 114 ). Then, on the basis of the real coordinates of a first reference position P 0 on the display unit and a real distance per a unit of display, the real coordinates of a second reference position P 1 set on the display unit ( 114 ) are obtained. Then, on the basis of the real coordinates of the second reference position and an offset from the second reference position to the base station ( 140 ), the real coordinates indicating the position P 2 where the base station is located are obtained, and these real coordinates indicating the position P 2 are registered in the database.
