Abstract
A base-station control apparatus includes: a sub-anchor candidate selector that selects sub-anchor candidates from base-station apparatuses different from a first base-station apparatus connected to a wireless terminal; an arrival-direction estimator that estimates arrival direction vectors with respect to the first base-station apparatus and the candidates, based on reception qualities of signals that the first base-station apparatus and the candidates receives from the wireless terminal; a sub-anchor selector that selects a sub-anchor from the candidates, based on angles made by the estimated arrival direction vectors and line segments each having end points at positions of the first base-station apparatus and the corresponding candidate; and a position estimator that estimates a position of the wireless terminal, based on the arrival direction vectors with respect to the first base-station apparatus and the sub-anchor.
