METHOD AND MOBILE COMMUNICATION REPEATER FOR CONTROLLING FREQUENCY BAND

摘要

PURPOSE: A method and a mobile communication repeater for controlling a frequency band are provided to easily perform service conversion operation for a frequency band only through remote control operation in the occurrence of a frequency return timing. CONSTITUTION: A first frequency pass filter(130) passes through a frequency band for a UL(UpLink) or DL(DownLink), and a second frequency pass filter(132) only passes through a second frequency band corresponding to the some of the first frequency band. If a frequency band conversion command is received, a relay device controller(140) converts the first frequency band into a second frequency band, wherein the first frequency band is set as a used frequency band through the control operation of the first and second switch operations.
