The embodiment of the invention relates to a method and equipment for determining cell relationship, and a method and equipment for planning frequency. The method for determining the cell relationship comprises the following steps: determining a service centre point of a service cell according to site positions in the coverage of the service cell and the azimuth direction of the service cell; determining the service centre point of an adjacent service cell according to the site positions in the coverage of the neighboring cell and the azimuth direction of the neighboring cell; and determining a first cell relationship quantization value of the service cell and the neighboring cell according to the distance between the service centre point of the service cell and the service centre point of the neighboring cell. In the embodiment of the invention, because topology information can reflect real network relationship, the first cell relationship quantization value acquired according to the topology information of the site positions, the azimuth direction and the like has little error and high accuracy.
Description
Technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a method and device for determining a cell relationship, and a method and device for frequency planning. Background technique [0002] Starting in the 1980s, mobile communication systems have introduced a cellular structure. The cellular structure is characterized by dividing all areas to be covered into several smaller areas, and setting up a base station in each area to cover the area. The user service, and users in the area covered by different base stations can communicate. The base stations of the cellular mobile communication system are arranged at intervals within the coverage area. The area covered by each base station can be divided into 1 to N cells. Cells separated by several cells can use the same frequency, so the same frequency can be used. Reuse to increase system capacity. [0003] In a frequency division multiple access (Frequency ...
