Embodiment Construction

[0067] In order to make the object, technical solution, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0068] The main idea of ​​the present invention is: collect and select the original data needed to determine the base station antenna azimuth angle deviation of the source cell from the operation and maintenance center (OMC) database, The interference ratio and the positional relationship between the base station of each sampling point and the base station of the source cell determine the azimuth angle deviation of the base station antenna of the source cell. If the azimuth angle of the base station antenna of the source cell has a deviation greater than the preset threshold, the corresponding azimuth angle will be displayed on the system Deviation information.

Abstract

The invention discloses a method for determining deviation of an azimuth angle of a base station antenna. The method comprises the following steps: step A, original data required for determining the deviation of the azimuth angle of the base station antenna of a source cell is acquired and selected from a database of an operational and maintenance center OMC; and step B, the deviation of the azimuth angle of the base station antenna of the source cell is determined according to the acquired and selected original data. Based on the measured data of mobile terminals, whether the azimuth angle of the base station antenna deviates or not can be quickly judged by using the carrier-to-interference ratio and the distance relation of the source cell and the cells where all the mobile terminals are positioned, and the work load of measuring the azimuth angle of the antenna by a network maintainer can be greatly reduced at present; and meanwhile, a basis of network service quality degradation caused by quick positioning and azimuth angle deviation overcoming is provided for the network maintainer.

Description

technical field [0001] The invention relates to the base station antenna technology in mobile communication, in particular to a method for determining the azimuth angle deviation of the base station antenna. 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 for configuring the base station antenna, the antenna azimuth is a very important part. On the one hand, the accurate azimuth can ensure that the actual coverage of the base station is the same as expected, and ensure the operation quality of the entire network; Optimize the existing mobile communication network well. However, in an actual mobile communication network, the antenna azimuth sometimes shifts due to natural disasters such as strong winds and earthquakes, which will lead to a decrease in the quality ...
