Embodiment 1

[0052] Embodiment 1: as Figure 1~5 As shown, the method for determining the cell relationship includes the following steps:

[0053](1) Obtain the latitude, longitude and azimuth of each cell;

[0054] (2) Determining the scope of the layer circle: draw at least one circle with the planning community as the center of the circle, then set the radius of the first layer circle as M meters, and then expand a layer circle outwards, and the radius increases by M meters; (M is 2 times the average station Spacing, the general area can be set to M = 1000 meters), such as figure 2 shown

[0055] (3) Partitioning and drawing a parabola: take the planning area as the center of the circle, and take the north direction as the starting position, divide the circle drawn in step (2) into several fan-shaped areas, and then obtain the base station of each fan-shaped area closest to the center of the circle position, at this time, it is necessary to remove the previously selected base statio...

Embodiment 2

[0073] Embodiment 2: The device for determining the relationship between the cells includes an acquisition of latitude and longitude and azimuth unit 601, a calculation layer circle range and a partition unit 602, a drawing parabola unit 603, and a generation circle relationship unit 604, and the unit 601 for obtaining the latitude and longitude and azimuth angle The longitude, latitude and azimuth angle of the acquisition cell for the acquisition cell; the calculation layer circle range and partition unit 602 is used to calculate the layer circle;

[0074] The drawing parabola unit 603 is used to draw a parabola for the base station cells within the circle range, and exclude the base station cells within the parabola to avoid cell interference;

[0075] The generating layer circle relationship unit 604 is used to calculate the area attributes of the remaining cells after removing the base station cells that do not meet the requirements, and calculate the forward or backward ce...

Embodiment 3

[0076] Embodiment 3: In this embodiment, the method of Embodiment 1 and the device of Embodiment 2 are adopted, and a community in an area of ​​a certain city is selected to illustrate the determination of the relationship between the communities; Figure 7 As shown in , take the cell pointed by the arrow as an example, and calculate the relationship between this cell and other surrounding cells;

[0077] (1) Obtain the latitude, longitude and azimuth of each cell from the engineering parameter table of the existing network;

[0078] (2) Draw a circle with the community as the center, calculate 3 layers of circles, and set the radius as 1000 meters, 2000 meters and 3000 meters respectively with the planned community as the center, such as Figure 8 shown;

[0079] (3) Partition and draw a parabola: take the planning area as the center and the north direction as the starting point, divide it into a fan-shaped area every 18°, and divide it into 20 fan-shaped areas in total, suc...

Abstract

The invention relates to a method and a device for determining a cell relationship. The correction method comprises the following steps of: (1) acquiring longitude, latitude and azimuth angles of eachcell; (2) determining a layer circle range, namely drawing at least one circle by taking the planned cell as a circle center, setting the radius of the first layer circle to be M meters, and increasing the radius by M meters every time when one layer circle is expanded outwards; (3) partitioning and drawing a parabola; planned cell as circle center, the north direction is used as a starting position; (3) dividing the circle drawn in the step (2) into a plurality of fan-shaped areas, obtaining the position of a base station, closest to the circle center, of each fan-shaped area, drawing a rotating parabola with the radius of a base station cell penetrating through the to-be-confirmed layer circle relation as the central axis and the base station cell with the to-be-confirmed layer circle relation as the vertex, and obtaining a layer circle relation cell; (4) calculating layer circle cell direction attributes; and (5) after the calculation of the first layer circle relationship is completed, removing the base station cell belonging to the first layer circle, and then repeating the steps (2) to (4) to calculate a plurality of expanded layer circle relationships.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for determining cell relationships. Background technique [0002] Since the 1980s, the mobile communication system has introduced a cellular structure networking method. The cellular structure is characterized by dividing all areas to be covered into several smaller areas, and setting up a base station in each area for the coverage of the area. Users in the service area covered by different base stations can communicate. Each base station of the cellular mobile communication system is placed at intervals in the covered area, and the area covered by each base station can be divided into 1 to N cells. The cells separated by several cells can use the same frequency, so the same frequency can be repeated. utilization, thereby increasing the system capacity. In a communication system, allocation of code resources is planned with reference to cell r...
