METHOD FOR MOBILE COMMUNICATION SERVICE USING DEDICATED FREQUENCY AND APPARATUS THEREOF

摘要

The present invention is directed to a method and device for mobile communication service, more specifically to a method and device for mobile communication service using a dedicated frequency. The method for providing mobile communication service, in which a dedicated frequency conversion unit utilizes a dedicated frequency in a predetermined area, based on a preferred embodiment of the subject invention, comprises the acts of receiving a signal of said dedicated frequency transmitted from said dedicated frequency base station, corresponding a signal of common frequency to a signal of said received dedicated frequency, and transmitting a signal of said corresponded common signal, wherein mobile communication terminals can receive a signal of said common frequency from said dedicated frequency conversion unit in said predetermined area and make a transition to a dedicated frequency bandwidth. According to the present invention, a separate, dedicated frequency can be used in a particular area or building, where PN pollution is severe, to prevent PN pollution from occurring and provide a relatively interference-free, high quality mobile communication service.
