摘要： A method for radio resource allocation in a wireless communication system comprises the steps of: receiving a channel indicator for indicating the frequency band used by a neighboring base station from a gateway that controls at least one base station that accesses the core network of a wireless communication system via an IP network; assigning to an available channel list a frequency band remaining after the frequency band indicated by said channel indicator is excluded from the entire frequency band, wherein said entire frequency band is divided into a plurality of frequency bands, and said channel indicator comprises indices that indicate respective frequency bands; and selecting, as one's own channel, at least one frequency band from said available channel list. The method enables finding of frequency bands which are used by neighboring base stations, and selection and use of a frequency band which is not used by neighboring base stations, and thus can reduce the interference between neighboring base stations, and efficiently use limited wireless resources.

摘要： A handover method according to one embodiment of the present invention comprises the steps of receiving the result of a cell measurement for a neighbor cell from a terminal, judging whether the neighbor cell is a near neighbor cell in accordance with the result of the cell measurement, calculating the ratio of the near neighbor cell to the total neighbor cells, and transmitting a command for a handover to a target cell to the terminal if the ratio exceeds the handover threshold value. The handover method of the present invention reduces interference between cells, and efficiently uses radio resources.
