A method and device for establishing a wireless interference matrix

Abstract

The invention provides a radio interference matrix establishing method and device. The method includes: acquiring voice business data and data traffic data of a main cell; determining co-frequency interference probability and adjacent-frequency interference probability of the main cell and an interference cell on the basis of the voice business data and the data traffic data of the main cell; structuring a radio interference matrix of the main cell on the basis of the co-frequency interference probability and the adjacent-frequency interference probability. The voice business data and the data traffic data are fused, so that network evaluation is more complete, and interference relation between the cells can be more accurately determined.

Description

technical field [0001] The present invention relates to the technical field of communication, and specifically relates to a method and a device for establishing a wireless interference matrix. Background technique [0002] The traditional frequency planning and interference analysis and positioning technology of GSM mobile communication network takes the coverage area of ​​the cell as the analysis object, and on this basis, the basic data are based on the cellular coverage theory, wireless propagation model or measurement report. [0003] Due to the large difference in the area of ​​the cells, the accuracy of the quantitative analysis of the coverage and interference relationship between the cells is negatively affected. [0004] Secondly, for a cell with a large coverage area, network problems caused by local interference inside the cell are easily overlooked, which also makes it difficult to analyze and locate the cause of interference. [0005] At the same time, the exis...

Problems solved by technology

[0003] Due to the large difference in the size of the cell area, it has a negative impact on the accuracy of the quantitative analysis of the coverage and interference relationship between the cells.

[0004] Secondly, for a cell with a large coverage area, network problems caused by local interference inside the cell are easily overlooked, which also brings difficulties in analyzing and locating the cause of interference.

[0005] At the same time, the existing technology mainly constructs the inter-cell interference matrix based on the measurement report (MR) data reported during the voice service call. At present, the data service in the GSM network accounts for more than 50%. The accuracy of the inter-cell interference relationship in the network is bound to be insufficient. At the same time, there are very few studies on cell interference during the data service period, and the depth is relatively lacking.

[0006] Therefore, the existing construction of a wireless network interference matrix that quantifies the coverage and interference relationship between cells has limitations in practical engineering applications
