Abstract

The invention provides a method for confirming a neighboring relation, which comprises the steps of acquiring the shadow fading margin under a multi-cell model and a link loss error of a propagation model in the propagation direction, carrying out correlation on the propagation model according to the shadow shading margin under the multi-cell model and the link loss error, carrying out overall coverage prediction analysis simulation by using the corrected propagation model so as to acquire a cell RSPP (Reference Signal Received Power) value received by each longitude and latitude grid point in a planned area, and processing the cell RSPP value received by each longitude and latitude grid point in the planned area so as to confirm a neighboring relation between cells. The invention further provides a device for confirming the neighboring relation. The neighboring relation confirming accuracy can be improved by the method and the device provided by the invention.

Description

technical field

[0001] The invention relates to the field of wireless mobile communication, in particular to a method and a device for confirming the relationship between neighboring cells. Background technique

[0002] Currently, there are several methods for confirming the neighbor relationship:

[0003] Method 1: On the basis of google map or planet format map and propagation prediction, obtain the signal strength of each cell received by each map grid point in the planning area through simulation, and calculate and add according to the signal strength distribution in the planning area Neighbor list.

[0004] Method 2: According to different propagation models, the field strength prediction distance is artificially set to 3 kilometers, 5 kilometers, etc., and then the cells with the cell position as the center and the radius as the field strength prediction distance range are regarded as candidate neighbors. Then the adjacent cells are further screened according to fact...
