Method and device for predicting cell interference

Abstract

The invention discloses a method and a device for predicting cell interference. The method comprises the following steps: dividing a coverage area of a cell to be predicted into grids, and determining latitude and longitude information corresponding to each grid; acquiring latitude and longitude information of a base station in the cell to be predicted, and acquiring latitude and longitude information and signal transmission power of a base station in a cell adjacent to the cell to be predicted; calculating a distance from each grid to each base station according to the latitude and longitude information of each grid and the acquired latitude and longitude information of the base stations; and determining interference values of the cell adjacent to the cell to be predicted for each grid according to a propagation model, the distance from each grid to each base station and the signal transmission power of the base station. The method and the device can realize the prediction for the cell interference.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell interference prediction method and device. Background technique [0002] In the field of mobile communication, there will be interference between adjacent cells. Therefore, it is necessary to control and coordinate the interference received by the cell, so that terminal users in the cell can obtain better user experience. The premise of controlling and coordinating the interference received by the cells is to obtain the interference received by each cell. [0003] At present, the existing technology can only realize the measurement of the interference situation of the cell. Specifically, the MR data reported by each terminal in a certain cell X is collected first, and then the Received Signal Code Power (RSCP, Received Signal Code Power) in the MR data is collected. , the ratio of energy per chip to noise power density (EC / N0) and other parameters are counted, so as to o...

[0003] At present, the existing technology can only realize the measurement of the interference situation of the cell. Specifically, the MR data reported by each terminal in a certain cell X is collected first, and then the Received Signal Code Power (RSCP, Received Signal Code Power) in the MR data is collected. , The ratio of energy per chip to noise power density (EC / N0) and other parameters are counted to obtain the interference situation of cell X

[0004] However, the above-mentioned measurement of cell interference is obtained based on the data actually reported by the terminal. When there is no data reported by the terminal, the existing technology cannot realize the prediction of the cell interference
