Abstract: A frequency control apparatus and method for railway wireless communication are provided. The frequency control apparatus includes a variable frequency processor and a fixed frequency processor. The variable frequency processor selects an available variable frequency and wirelessly receives non-safety-related train running information from a base station at the selected variable frequency. The fixed frequency processor wirelessly receives safety-related train running information at a predetermined fixed frequency.

Abstract: The present invention relates to a mobile communication system, and more particularly, to a repeater and a ranging method using the repeater. In the mobile communication system including the repeater, a ranging operation is performed so that data are transmitted to a base station regardless of whether a mobile terminal is within a repeater area. Accordingly, it is determined whether a ranging code received through a ranging flag is directly received from the mobile terminal or if it is received through the repeater. When the ranging code is transmitted to the base station through the repeater, the ranging operation of the mobile terminal is performed.
