Problems solved by technology

[0007] Regarding the above process, the inventor believes that this method has at least the following disadvantages: the judgment of neighboring cells is completely based on geographical information, and the characteristics of wireless propagation are not considered, that is to say, the situation of wireless propagation is not used as the basis for judgment of neighboring cells
Therefore, when the wireless propagation is affected by various factors and the geographic information differs, it will cause errors in the judgment results of neighboring cells.
Moreover, the calculation speed of this method is relatively slow, and it cannot perform fast and accurate planning processing on large networks.

Embodiment Construction

[0026] The implementation of the present invention will be further described below in conjunction with the drawings and examples.

[0027] In Embodiment 1 of the present invention, a process flow of a neighboring cell planning method is shown in FIG. 2, including the following steps:

[0028] Step s201, setting sampling points in the area to be planned.

[0029] The sampling point setting method can be set according to needs, for example, the existing rasterized network sampling point setting method is adopted.

[0030] Step s202, obtaining the coverage strength of each cell in the area at the sampling point.

[0031] The manner of obtaining the coverage strength may be calculated using conditions such as cell parameters and propagation models.

[0032] Step s203 , perform neighbor cell planning for each cell according to the coverage strength.

[0033] In this step, the neighbor cell planning of each cell is carried out based on the coverage condition of the cell as the cr...

Abstract

The method comprises: setting a sampling point in the planning area; getting the signal coverage strength of each cell in the area; according to the signal coverage strength, making the planning for the adjacent cells of each cell, the invention also reveals an apparatus for planning the adjacent cells.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for planning adjacent cells. Background technique [0002] The neighbor cell is one of the most basic configurations of the wireless access network communication system, and it is the basic condition for the wireless network communication system to perform fast handover. Neighbor cell planning is to provide necessary support for the network to establish handover, and it is beneficial to quickly select the destination cell during handover. With the continuous development of wireless network communication technology, there is a strong demand for automatic neighborhood planning using planning algorithms. [0003] In the prior art, a coverage-based automatic planning algorithm for wireless network neighbors is proposed. This algorithm is based on the distance between various cells in the wireless network and the direction angle of the antenna of e...
