The invention belongs to the communication technical field and discloses a frequency re-planning method and apparatus. The method includes the following steps that: at least one frequency point available to a cell to be subjected to frequency re-planning is determined; as for any frequency point in the least one frequency point, a co-frequency coefficient when the cell to be subjected to frequency re-planning adopts any frequency point is determined, wherein the co-frequency coefficient is used for characterizing the magnitude of interference of co-frequency cells on the cell to be subjected to frequency re-planning; and a frequency point corresponding to the maximum co-frequency coefficient is adopted as a frequency point adopted by the cell to be subjected to frequency re-planning. According to the frequency re-planning method and apparatus of the invention, when existing technologies are adopted to allocate frequency points for a cell for which frequency point allocation fails outdoors, the frequency points are not selected in a random manner, but are frequency points which are selected from available frequency points and are corresponding to the maximum co-frequency coefficient, and the higher the maximum co-frequency coefficient is, the smaller cell interference is, thus, when the method provided by the invention is adopted to select frequency points, the cell interference can be decreased, and problems existing in the prior art can be solved.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a frequency flipping method and device. Background technique [0002] When the network is expanded in a large amount (including new sites and capacity expansion), the frequency reuse is too high, resulting in serious frequency interference. It is necessary to re-plan the frequency of the entire network (that is, frequency flipping) to make the frequency of the entire network more reasonable. To achieve the purpose of eliminating interference between cells. [0003] The specific frequency flipping process is to collect network information and network data, conduct network assessment, analyze the problems existing in network frequency planning, form a frequency re-planning plan, and then use frequency flipping software to make a detailed frequency planning plan, and cut over after review and revision It is poured into the existing network, and optimized and ...
