Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for setting frequency points of a mobile communication system. Background technique [0002] Frequency reuse is the core concept of a cellular mobile communication system, that is, users in cells separated by a certain distance can use the same frequency, thereby greatly improving spectrum efficiency. The mechanism of frequency reuse is based on the characteristics of radio wave propagation path loss, that is, assuming that the distance between two base stations is far enough, the frequency used for one base station can be reused on another base station. The area covered by each base station is called a cell, and the size of the cell depends on the density of users. Cells that use the same frequency are called co-frequency cells. The distance between these co-frequency cells must be far enough that the level of co-channel interference is...

AI Technical Summary

Problems solved by technology

[0008] When frequency planning is based on the physical location of the cell, due to the limitation of map accuracy, the accuracy of the physical location of each cell is not high, coupled with the constraints of theoretical analysis accuracy, simulation parameters and other conditions, the obtained frequency planning scheme is often not optimal

[0009] When carrying out frequency planning based on drive test information, a large amount of manpower and material resources are required to carry out drive test. In addition, because the drive test based on the entire network consumes too much manpower and material resources, it is usually not used in practical applications. Therefore, based on drive test information Frequency planning can only optimize frequency point settings in some areas

In addition, since the drive test information in the measurement area is also limited, the frequency point optimization effect for the measurement area is also limited
