Method and device for determining cell interference relationship

Abstract

The invention discloses a method for determining a cell interference relationship. The method comprises the following steps: acquiring signal parameters of a serving cell and each interfering cell inan area to be measured through different data sources; respectively determining a single data source interference matrix of the serving area corresponding to each data source according to the signal parameters of the serving cell and each interfering cell; and fusing the single data source interference matrix of the serving area corresponding to each data source into a multi-data source interference matrix of the serving area according to a preset weight and a sampling point difference of each data source. The invention further discloses a device for determining the cell interference relationship.

At the same time, the optimization related to the interoperability of different system systems is becoming more and more complicated

At present, the general method for planning and optimizing adjacent areas of mobile communication networks is to use geographical dimension analysis, and carry out planning and optimization through manual or semi-automatic methods. , there is also the possibility of human error, unreasonable planning will lead to communication interruption, user perception deterioration and other problems;

[0003] Since the neighbor cell is one of the most important parameters for maintaining communication continuity in the network, the interference relationship of the cell must be determined first before the neighbor cell planning; the traditional method of constructing the interference matrix of the neighbor cell is usually based on the level difference of sampling points between the serving cell and the interfering cell Doing step-by-step discrete linear simulation cannot better reflect the nonlinear continuous interference changes brought about by level signal fading or enhancement, or although nonlinear simulation is used, it fails to fully consider the proportion of sampling points in different interference cells to the interference probability band to influence
