Abstract: A method for providing a multicast service from a macrocell or a microcell to a mobile station in a mobile communication system having a hierarchical cell structure in which a given area is divided into at least one macrocell and at least one microcell overlapping with each other. The mobile station receives a multicast service by accessing the macrocell or the microcell according to a carrier-to-interference ratio (C/I) for the multicast service measured in a macrocell area and according to an existence or non-existence of a concurrent call currently in service.

Accordingly, a color saturation of the image is not decreased even with addition of the achromatic color component.
