1. A management method for coverage optimization, the method comprising: obtaining, by a management apparatus for coverage optimization, measurement reports of a coverage optimization target region; determining, by the management apparatus for coverage optimization, an actual value of a coverage optimization target within the coverage optimization target region according to the measurement reports; and performing, by the management apparatus for coverage optimization, coverage optimization processing on the coverage optimization target region when the actual value of the coverage optimization target is smaller than a preset expected value of the coverage optimization target.
