However, in practical applications, for a site with a considerable coverage radius, the interference is distributed in all angles of the site's coverage area, and in many cases the interference cannot be perceived only through the uplink measurement of the base station
The traditional base station operating frequency point configuration scheme is applied to the frequency point self-optimization of large base stations, which has the disadvantage of low optimization reliability

Embodiment Construction
[0021]In one embodiment, a method for self-optimizing the operating frequency of a base station, such asfigure 1 As shown, including the following steps:
[0022]Step S110: Obtain the base station side interference value measured by the base station side uplink of the frequency point to be measured.
[0023]The base station side interference value is a physical quantity that measures the interference situation corresponding to the frequency point to be measured, and can be received power, signal-to-noise ratio, signal-to-interference-noise ratio, carrier-to-interference-noise ratio, etc., and the specific type is not limited. Specifically, the base station side interference value measured on the base station side of the frequency point to be measured is obtained through the base station. When the base station is subjected to continuous strong interference, the base station's operating frequency self-optimization operation is triggered, and the frequency self-configuration process is enter...

The present invention relates to a self-optimization method and a device for the working frequency point of a base station. According to the method, the interference value of a base station side, during the uplink measurement of to-be-measured frequency points on the base station side, is obtained. After that, the interference value of a terminal side, during the downlink measurement of the to-be-measured frequency points on the terminal side, is obtained. According to the interference value of the base station side and the interference value of the terminal side, the comprehensive interference values of the to-be-measured frequency points are calculated and obtained. One corresponding to-be-measured frequency point, with the comprehensive interference value thereof to be minimum, is adopted as the working frequency point of the base station. The calculation of the interference value fully considers the measurement result of the base station side and the measurement result of the terminal side. Therefore, the interference condition in each area within the coverage range of the base station can be effectively perceived. The method and the device can meet the self-optimization requirements of the frequency points of small base stations, and can also meet the self-optimization requirements of the frequency points of large base stations. The selected working frequency point is higher in reliability, so that the self-optimization reliability of the frequency points of the base station is improved. Furthermore, the communication reliability of the base station is improved.
Description
Technical field[0001]The present invention relates to the field of wireless communication technology, in particular to a method and device for self-optimizing the operating frequency of a base station.Background technique[0002]With the development of wireless coverage technology, frequency point self-configuration and self-optimization technologies have been continuously strengthened and are widely used in various forms of networking applications.[0003]The traditional base station working frequency configuration scheme mainly adopts the single-site frequency interference minimization selection method. By measuring the alternative frequency points on the base station side, the frequency point with the least interference is determined as the working frequency point, and then the frequency point self-configuration or Self-optimizing. In practical applications, for a site with a considerable coverage radius, interference is distributed at all angles of the site's coverage area. In many ...
