Problems solved by technology

[0004] However, it is inaccurate to determine the cell to be calculated according to the plane distance in the network topology information, because in practice, the cell with the closer plane distance may also be farther in the actual physical distance, for example, two cells in the network topology The plane distance represented in the information is very close, but the base station of one cell is on the ground, and the base station of another cell is on a high-rise building, the actual physical distance between the two cells may also be relatively far

Embodiment 1

[0038] An embodiment of the present invention provides a method for determining a cell relationship, such as figure 1 Shown is a schematic flow chart of the method, including:

[0039] S101. Obtain a layer-1 neighbor cell of the target cell.

[0040] Wherein, the first-level adjacent cell of the target cell is a cell whose spatial distance from the target cell is smaller than a first preset value, and the spatial distance is used to indicate the positional relationship between the two cells.

[0041] Specifically, the location relationship between the two cells includes the distance relationship between the two cells and the direction relationship of the antennas of the base stations to which the two cells belong.

[0042] In a mobile communication system, in order to perform reasonable code resource planning for all cells in an area, it is necessary to determine cell relationships among all cells. Specifically, all the cells in the area are sequentially used as target cells...

Embodiment 2

[0056] An embodiment of the present invention provides a method for determining a cell relationship, such as figure 2 Shown is a schematic flow chart of the method, including:

[0057] S201. Acquire configuration parameters of a target cell.

[0058] Wherein, the configuration parameters of the target cell include at least the geographic coordinates of the target cell and the antenna height of the base station to which the target cell belongs.

[0059] Specifically, the geographic coordinates of the target cell are converted from the latitude and longitude in the parameters of the network project during construction into geographic coordinates (x1, y1). Also specifically, the antenna height of the base station to which the target cell belongs includes ground object height, building height, and antenna hanging height.

[0060] S202. Acquire configuration parameters of the first cell.

[0061] Wherein, the first cell is any cell in the neighbor list of the target cell, or an...

Embodiment 3

[0169] An embodiment of the present invention provides a device for determining a cell relationship, such as Figure 7 Shown is a schematic structural diagram of the device, including:

[0170] The first acquiring module 10 is configured to acquire a layer-1 neighbor of the target cell, wherein the layer-1 neighbor of the target cell is a cell whose spatial distance from the target cell is smaller than a first preset value, wherein the spatial distance Used to indicate the location relationship between two cells.

[0171] The first determining module 11 is configured to determine a first cell relationship value between the target cell and a layer-1 neighbor of the target cell, wherein the first cell relationship value is used to indicate the relationship between the target cell and the layer-1 neighbor of the target cell community relationship.

[0172] The unit also includes:

[0173] The second obtaining module 12 is used to obtain the second-layer adjacent area of ​​the ...

Abstract

The embodiment of the invention provides method and device for determining community relations, and aims at gaining each adjacent community of which the relation to a target community is to be calculated according to the space distance of the communities so as to obtain accurate community relations. The method comprises the steps of acquiring one-layer adjacent community of the target community, wherein the space distance from the one-layer adjacent community of the target community is less than that of the community at the first preset value; determining the first community relation value between the target community and the one-layer adjacent community of the target community, wherein the first community relation value is used for indicating the community relation of the target area and the one-layer adjacent community of the target community.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for determining cell relationships. Background technique [0002] In a communication system, allocation of code resources is planned with reference to cell relationships. Generally, if the same code resource is allocated to closely related cells, the interference in the communication network will be relatively large, and if the same code resource is allocated to distantly related cells, the interference in the communication network will be relatively small. Therefore, in order to make the allocation of code resources more reasonable, it is necessary to determine a more accurate cell relationship before allocating code resources. [0003] In the prior art, the cell relationship between each cell to be calculated and the target cell is obtained based on network topology information. Specifically, each cell to be calculated is obtained according to the plan...
