Abstract

The invention discloses an establishment method of an adjacent cell list. A range of a determination area is determined according to a channel quality of a cell; and when a common covering factor in an adjacent cell list is calculated, the channel quality parameter of the cell and a channel quality parameter of a to-be-determined cell are referenced. According to the disclosed method in the invention, accuracy of a common covering factor in an adjacent cell list can be effectively improved.

Description

technical field

[0001] The invention relates to the field of wireless communication, in particular to a method for establishing a neighbor list. Background technique

[0002] The main purpose of neighbor cell planning is to reasonably configure neighbor cells for each cell based on factors such as the geographic location and channel environment of each cell. The neighbor list is one of the basic configurations of each cell and is used in wireless communication systems. To realize fast handover between cells, one of the important steps in the process of neighbor cell planning is to establish a cell neighbor list.

[0003] First of all, it needs to be explained that three factors are mainly considered in determining the neighbor cell relationship of a cell: co-site, adjacency and co-coverage. Co-site means that two cells belong to the same base station, adjacency means that the distance between the two cells is relatively close, and co-coverage means that the co-coverage area...

Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0053] figure 2 It is a flowchart of a method for establishing a neighbor list provided by the present invention. Such as figure 2 As shown, the method includes the following steps:

[0054] Step 201, divide the coverage area of ​​the cell into multiple grids, and obtain the channel quality of the cell at each grid, starting from when the channel quality of the cell is less than the preset channel quality upper limit value, to the channel quality of the cell The area until the channel quality is less than the preset channel strength lower limit is determined as the judgment zone S A , where the judgment band S A The sum of the number of grids in is J.

[0055] It should be noted that the difference between this step and step 101 ...
