Abstract
A control apparatus that determines a relief carrier that relieves communication in a failure area occurring when an antenna of a wireless base station fails and a tilt angle of the relief carrier includes: a failure area aggregation unit that aggregates a plurality of adjacent failure areas to collectively generate a single aggregated failure area; a relief carrier selection unit that selects a plurality of relief carriers for the aggregated failure area; and a tilt angle determination unit that simultaneously optimizes a plurality of tilt angles in the plurality of relief carriers.
