Embodiment 1

[0032] Basic as attached figure 1 Shown: the cell azimuth evaluation method based on measurement data, including the following steps:

[0033] Information obtaining step: obtaining user data formed by the user during the network wireless management process. That is, to obtain OMC-R data, that is, MR data, MR (Measurement Report, measurement report) data is composed of information extracted from the periodical measurement report reported from UE to eNodeB (LTE base station) or the event report that triggers handover, these The measurement report carries the relevant information of the uplink and downlink radio links, including reference signal received power, reference signal received quality, timing advance, eNodeB antenna angle of arrival, eNodeB received interference power, etc.

[0034] Azimuth acquisition step: Obtain the reference azimuth of the base station antenna of the cell occupied by the user according to the user data.

[0035] Direction acquisition step: summari...

Embodiment 2

[0039] Example 2 (eg figure 2 shown)

[0040] Compared with Embodiment 1, the only difference is that a review step is also included between the comparison step and the determination of the suspected step. The review step: rotate the base station antenna by 5° after the interval of periodic measurement, so that the suspected antenna Adjacent antennas are used to serve users who are suspected to have been served by the antenna, and the ratio of the number of users outside the theoretical coverage to the total number of users actually served by the base station antenna is recalculated. If the ratio for the second time is greater than the preset value, continue to rotate. If the ratio is less than the preset value, and there is still no suitable angle to make the ratio smaller than the preset value after one rotation, then the cell is determined to be a suspected cell; if the second ratio is smaller than the preset value, it is judged that the suspected antenna is damaged and th...

Abstract

The invention belongs to the technical field of mobile communications, and specifically provides a cell azimuth angle assessment method for solving the technical problem that the existing cell azimuth angle checking has blindness and large workload. The method comprises the following steps: an information acquisition step: acquiring user data of a user formed in network wireless management process; an azimuth angle acquisition step: acquiring a reference azimuth angle of a cell base station antenna occupied by the user according to the user data; a direction acquisition step: summarizing and analyzing the reference azimuth angle to acquire an actual distribution direction and distribution condition of the user in the cell; and a comparison step: determining a suspected step. The invention discloses a cell azimuth angle assessment system based on the measurement data.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a measurement data-based cell azimuth evaluation system and method. Background technique [0002] The azimuth is one of the important parameters of the wireless network, and the azimuth of the cell determines the coverage direction of the wireless signal of the cell. In daily wireless network optimization, engineers obtain cell azimuth angle information through cell basic data tables. The azimuth angle of the base station changes due to strong wind, or the antenna is damaged, which is the cause of the error between the theoretical value and the actual value of the azimuth angle), which leads to the deviation between the azimuth angle of the cell in the basic data table of the cell and the actual azimuth angle. Therefore, checking the azimuth angle is one of the important tasks of daily network optimization. [0003] Traditionally, the verification of the azimuth an...
