• wherein the information about the cell includes information about an area of the coverage area of the cell;
• and
• a determining unit which determines whether the coverage area of each cell described in the list is large or small, wherein
• the specific condition includes a condition in which the number of the cells of which each of coverage areas is determined as being small does not exceed a third threshold value.
