Abstract
An operation management system in a radio communication system, including a plurality of wireless base stations, includes: a cell determining means for determining a boundary of a cell by: collecting power transmitted, and antenna gain, from each wireless base station, computing a propagation loss from each of the wireless base stations at an arbitrary observation point, using a statistical technique employing an estimation model in which a radio wave damps depending upon distance or by use of a ray-tracing method, computing power received from each wireless base station at the observation point, deciding that the wireless base station that achieves maximum received power at the observation point is a connection base station at the observation point, and determining the space between points in which connection base stations differ as cell boundaries.
