Embodiment 1

[0041] In the above step S101, the position points represented by each base station are respectively mapped to discrete points on the plane. Specifically, the position points represented by the latitude and longitude of the base station can be respectively mapped to discrete points on the plane, such as figure 2 As shown, taking 11 base stations as an example, the location points represented by the latitude and longitude of the 11 base stations are respectively mapped to discrete points B1-B11.

[0042] In Embodiment 1 of the present invention, the above step S102 specifically includes: based on each discrete point, using the Thiessen polygon method to determine the coverage area of ​​the Thiessen polygon where each discrete point is located; Divide the coverage area of ​​the Thiessen polygon corresponding to the discrete point of the base station, and obtain the coverage area of ​​each cell formed by the base station. The detailed description is as follows:

Abstract

The invention discloses a method and a device for determining a neighbor cell of a cell. The method comprises the following steps: the characterization position points of base stations are respectively mapped to discrete points on a plane; based on each discrete point, the coverage range of each cell of each base station is determined by adopting Thiessen Polygons; and according to the relationship between the coverage range of the current cell and the coverage range of other cells, the neighbor cell of the current cell is determined. By adoption of the embodiment of the invention, the accuracy and the efficiency of determining the neighbor cell of the current cell are improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and a device for determining a neighboring cell of a cell. Background technique [0002] With the rapid development of mobile communication networks, there are more and more network users, and the network structure is becoming more and more complex, so network maintenance is becoming more and more difficult. Therefore, it is very important to use effective means to monitor and optimize the network and improve the quality of network communication. Neighborhood optimization is an important part of it. [0003] One of the biggest differences between mobile communication networks and fixed-line networks is the mobility of user terminals. Therefore, during network operation, user terminals will switch serving cells, and due to network configuration and unreasonable use of network resources, it often leads to Cell handover fails, resulting in dropped c...
