Abstract: A method and an apparatus select optimized Frequency Allocation (FA) in a mobile communication system that includes mobile base stations. A first control information is received from neighbor base stations. System capacities of the respective neighbor base stations are determined based on the first control information. The FA that maximizes a sum of the system capabilities of the respective neighbor base stations is selected. Therefore, the method has an advantage of securing maximum capacity by adaptively setting FA with consideration of radio environments of neighbor base stations during network entry of a new mobile base station or during an operation of a mobile base station.
