Embodiment 1

[0053] Embodiment 1. In this embodiment, the target cell is cell A, and the specific method for configuring the neighbor cells of cell A is as follows, see image 3 :

[0054]Step 301: Sampling is performed in the area to be configured with adjacent cells according to a certain sampling rate, and the two signal strength values ​​with the highest signal strength received by the UE at each sampling point and the names of the corresponding cells are acquired and stored.

[0055] Here, the sampling rate may be sampled at 20×20 meters which is often sampled with map precision. At each sampling point, the signal strengths of all the cells received by the UE are sorted, and at each sampling point, the two signal strength values ​​with the highest signal strength received by the UE and the names of the corresponding cells are saved. The link budget method can be applied to obtain at each sampling point, the two signal strength values ​​with the highest signal strength received by the...

Embodiment 2

[0078] Embodiment 2: In this embodiment, the target cell is cell A, and the specific method for configuring the neighbor cells of cell A is as follows, see Figure 4 :

[0079] Step 401: Sampling is performed in the area to be configured with neighboring cells according to a certain sampling rate, and the two signal strength values ​​with the highest signal strength received by the UE and the names of the corresponding cells are obtained and stored at each sampling point. Here, after applying the drive test method to obtain the two signal strength values ​​with the highest signal strength received by the UE at each sampling point and the names of the corresponding cells, save the two cell information corresponding to each sampling point , including the names of the two cells and their corresponding signal strength values.

[0080] Step 402: From the information of the two cells corresponding to each sampling point saved in step 401, select the sampling point corresponding to ...

Abstract

The invention discloses a method for configuring adjacent cells, which is used to solve the problems of large amount of data storage and inaccurate results when configuring adjacent cells. The method includes: selecting a sampling point corresponding to the cell information of the target cell according to the information of two cells corresponding to each sampling point in the area, and selecting a sampling point corresponding to the cell information of the target cell according to the information of the target cell received by the mobile terminal (UE) at the sampling point Signal strength, add all the cells corresponding to the selected sampling points except the target cell to the neighbor list of the target cell, modify the information in the neighbor list of the target cell according to the set rules, and modify the information in the neighbor list of the target cell according to the revised The information in the following neighbor cell list configures the neighbor cells of the target cell. The invention also discloses a device for configuring adjacent cells.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for configuring adjacent cells. Background technique [0002] In a mobile network, when a terminal moves from one cell to another, the network should be able to support good handover, which is one of the basic requirements for the mobile network to provide services. In order to realize the handover, it is necessary to configure the neighboring cell relationship between the cells that may be handed over, and a good network requires a reasonable neighboring cell configuration scheme. Too few adjacent cell settings will lead to a decrease in the success rate of handover. Too many settings will firstly make the handover take too long and the signaling overhead will increase. In addition, it will also increase the time of pilot scanning, and in serious cases will lead to disconnection and can't access the network. Therefore, the configurati...
