Embodiment 1

[0068] An embodiment of the present invention provides a method for detecting cell handover coverage, such as figure 2 As shown, the method may include:

[0069] S101. The controller determines the direction of each neighboring cell of the cell to be detected relative to the cell according to network engineering parameters.

[0070] Wherein, the network engineering parameters are set in the controller according to the actual location information of each cell in the network during the network networking process. Specifically, in the implementation of the present invention, the network engineering parameters may at least include the latitude and longitude of each cell in the network (including the longitude and latitude of each cell in the network and the latitude of each cell in the network).

[0071] In the embodiment of the present invention, since the meanings of the directions of the neighbors of the cell relative to the cell are the same, in order to clearly indicate the...

Embodiment 2

[0090] An embodiment of the present invention provides a method for detecting cell handover coverage, such as Figure 4 As shown, the method may include:

[0091] S201. The controller determines each neighbor cell of the cell according to the neighbor cell relationship data of the cell.

[0092] Wherein, the neighboring cell relationship data is set in the controller according to the neighboring cell information of each cell in the network during the network networking process. When the neighbor cell information of the current cell changes, the controller can also update the neighbor cell relationship data. Specifically, the controller may instruct the base station serving the cell to report the changed neighbor cell information, and update the neighbor cell relationship data according to the changed neighbor cell information.

[0093] In the embodiment of the present invention, the neighboring cell relationship data may include identifiers of each neighboring cell of the ce...

Abstract

The invention provides a method and device for detecting cell cross-boundary coverage, and relates to the technical field of communication. Detection accuracy of cell cross-boundary coverage can be improved and human and material resources are saved. The method includes the steps that according to network engineering parameters, the directions of all adjacent cells of a current cell relative to the current cell are determined, and according to the directions of all the adjacent cells relative to the current cell, multiple first adjacent cells in all the cells are determined, wherein the first adjacent cells and the current cell have overlapping coverage regions; according to the network engineering parameters, the distances between the first adjacent cells and the current cell and the direction of second adjacent cells relative to other first adjacent cells are determined, and according to the distances between the first adjacent cells and the current cell and the directions of the adjacent cells relative to the other first adjacent cells, whether intermediate adjacent cells exist in other first adjacent cells or not is determined; when the intermediate adjacent cells exist in the other first adjacent cells, a controller can confirm that the cross-boundary coverage phenomenon exits in the current cell. The method is applied to cell coverage detection scenes.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for detecting crossover coverage of a cell. Background technique [0002] In a wireless network, if a cell crosses the coverage area of ​​one or more cells and overlaps with a cell that is farther away from the cell, it means that the cell is over-covered, that is, there is an over-coverage phenomenon in the cell. This over-coverage phenomenon causes the cell to cause serious interference to cells with overlapping coverage areas, and degrades the communication quality of the communication link in the cell, thereby seriously affecting the network performance of the wireless network. Therefore, it is necessary to detect whether a cell has cross coverage, and adjust the coverage of the cell with cross coverage in time to reduce the negative impact of cell cross coverage, thereby improving network performance. [0003] In the prior art, it is gener...
