Problems solved by technology

Base station antenna azimuth deviation refers to the deviation between the actual coverage direction of the antenna and the plan or database records; if the deviation of the antenna azimuth angle is too large, it will not only cause uneven traffic absorption by the site, difficulty in frequency planning, but also cause coverage problems, unable to Truly reflect information coverage in GIS
Generally, to check the azimuth of the community, it is necessary to manually analyze and check a large amount of data, and to go to the base station for on-site inspection and measurement, which greatly increases the difficulty of checking the azimuth. The workload of checking and maintenance is heavy, and the operating cost is high.

Embodiment 1

[0026] A method for checking the azimuth angle of a base station cell comprises the following steps in sequence:

[0027] (1) Collect data of base station cells: collect traffic switching data between cells from the OSS (Operation & Support System) server, and collect base station engineering parameters from the base station database;

[0028] The inter-cell traffic switching data is the inter-cell traffic switching data in the traffic statistics of the six peak hours at 9, 10, 11, 18, 19, and 20 o'clock every day;

[0029] The base station engineering parameters include the latitude and longitude of the base station, indoor coverage, cell type, area type, angle value of the azimuth angle and the arrangement sequence of the azimuth angles of the base station cells;

[0030] (2) Select the reference cell: select the 9 base station cells with the most handover relations among the adjacent base station cells that are more than 50 meters away from the base station cell to be check...

Embodiment 2

[0041] A method for checking the azimuth angle of a base station cell comprises the following steps in sequence:

[0042] (1) Collect data of base station cells: collect traffic switching data between cells from the OSS (Operation & Support System) server, and collect base station engineering parameters from the base station database;

[0043] The inter-cell traffic switching data is the inter-cell traffic switching data in the traffic statistics of the six peak hours at 9, 10, 11, 18, 19, and 20 o'clock every day;

[0044] The base station engineering parameters include the latitude and longitude of the base station, indoor coverage, cell type, area type, angle value of the azimuth angle and the arrangement sequence of the azimuth angles of the base station cells;

[0045] (2) Select the reference cell: select the 6 base station cells with the most handover relations among the adjacent base station cells that are more than 55 meters away from the base station cell to be check...

Embodiment 3

[0056] The difference from Embodiment 1 is that only three adjacent base station cells with the most traffic switching data are selected as reference cells.

[0057] The above-mentioned method of checking the azimuth angle of the base station cell is applied in the judgment of the dislocation of the base station cell sector: the weighted average value of the logical azimuth angles of the base station cells obtained in step (4) is arranged from small to large, and then compared with the cell of the base station configuration data The order of the azimuth angles is compared, and if the order of appearance is different, it is determined that the cell sector of the base station is misaligned.

Abstract

The invention discloses a method for checking an azimuthal angle of a base station cell, which comprises the following steps: acquiring data of the base station cell; selecting a reference cell; determining corresponding logic azimuthal angles of the base station cell to be checked and the reference cell; calculating a weighted average of the corresponding logic azimuthal angles of the base station cell to be checked and the reference cell; and judging and outputting a checking result of the azimuthal angle of the base station cell to be checked. A base station maintenance center can maintain a base station of which the azimuthal angle is deviated or back in a targeted manner according to the checking result. The checking method has a high checking accuracy and a high efficiency, reduces the manual maintenance workload and reduces the operating cost.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for checking the azimuth angle of a cell of a base station, so as to determine the sector misalignment of the cell to be checked. Background technique [0002] At present, in mobile communication systems, the transmission and reception of space wireless signals are realized by antennas. Therefore, antennas play a pivotal role in mobile communication networks. Among the various parameters of base station antenna configuration, the antenna azimuth angle is a very important part. On the one hand, accurate azimuth angle can ensure that the actual coverage of the base station is the same as expected, and ensure the operation quality of the entire network; on the other hand, The existing mobile communication network can be better optimized by properly adjusting the azimuth angle according to the traffic volume or the specific conditions of the network. However...
