PROBLEM TO BE SOLVED: To accurately detect a connection direction of each directional antenna installed in a radio base station.SOLUTION: An antenna connection direction detection apparatus collects hand-off information recorded in a radio base station. In the antenna connection direction detection apparatus, on the basis of base station data containing the latitude/longitude of the radio base station and an orientation direction of each directional antenna in the radio base station and the hand-off information, while defining a radio base station of a tabulation object as a starting point on a coordinate axis of the latitude/longitude and defining a radio base station of a hand-off destination as an ending point on the coordinate axis of the latitude/longitude, a direction of a vector connecting the starting point and the ending point is calculated for each directional antenna, each of the calculated directions is compared with a direction determination reference value, and it is determined whether each of the calculated directions is settled within a range of the direction determination reference value. |
