Problems solved by technology
[0006] The technical problem to be solved by the present invention is that when performing base station site selection in the TD-LTE system, it is necessary to consider the co-frequency interference of short-distance neighboring cells and the co-frequency of long-distance uplink and downlink cross-slot time slots, so as to avoid the interference of existing base stations as much as possible. When using the interference control range of the existing base station to cut the area to be planned, how to determine the priority order of the existing base station, there is no simple and objective implementation method, the interference cannot be dispersed, and the overall network cannot be truly improved Communication quality, which limits the quality of base station siting

The invention provides a TD-LTE system base station locating method and a TD-LTE system base station locating device. The method comprises the following steps: mapping location point information of existing base stations into a full base station point set on a plane; processing the full base station point set into a subdivision triangular mesh; calculating the ratio value of interference triangle area and level interval between any base station point and other base station points and sorting the base station points on the triangular mesh based on the interference priority; and cutting a to-be-planned base station area with the interference control range according to the interference priority order of the base station points and carrying out base station location in the cutting area. According to the invention, base station location point information is generated into a subdivision triangular mesh, and the interference priority of the base station points is determined by making use of the ratio value of interference triangle area and level interval on the triangular mesh, the obtained interference priority is calculated in the plane, no consideration needs to be given to the influence of topographic and geomorphic conditions, and no complex data statistics is needed.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for selecting a base station in a TD-LTE system. Background technique [0002] In the TD-LTE (Time Division Long Term Evolution) system, there are two ways of using the same frequency and different frequencies for outdoor networking. Among them, the same frequency networking means that all cells in the entire network use the same frequency points, and different frequency groups use the same frequency. The network mode means that different cells of the same base station use different frequencies. The advantages of the same-frequency networking are high frequency utilization, flexible frequency deployment, low demand for terminal support frequency bands, and reduced complexity of terminal RF channels. [0003] When the TD-LTE system uses co-frequency networking, the co-frequency interference of adjacent cells in the short distance and the co-frequency in...
