And then, the scheduler combines two or more basic modules which are successively executed according to a paralleled execution description in order to assign two or more basic modules as a module to a single execution unit, when a value of the parallel degree exceeds a predetermined value and a value of the load exceeds a predetermined value. If the former quality is not higher than the latter quality by a predetermined level or more, the radio communication base station is determined to still be subject to the influence of fading, and hand-over is not performed.
