Embodiment 1

[0049] Embodiment 1: Calculate the vector sum of the X-axis azimuth angle and the sum of the Y-axis azimuth angle vectors by using the following formula.

[0050]

[0051]

[0052] In the formula, X (cell) is the sum of the X-axis azimuth vectors, Y (cell) is the Y-axis azimuth vector sum, AOA (MR) is the sample value of MR.LteScAOA actually reported by the OMC-R northbound interface, and i is the corresponding (360-AOA (Angle) ) value, the minimum value is 0 degrees, the maximum value is 359.5 degrees, k is the AOA corresponding to the selected sampling sample (Angle) Whether there is sampling in unit time, it is recorded as 1 if it is, and it is recorded as 0 if it is not.

[0053] As shown in Table 2 above, here, if the value reported by the OMC-R northbound interface is defined as 0, the corresponding angle is 0 degrees, 1 corresponds to 0.5 degrees, 2 corresponds to 1 degree, ..., 719 corresponds to 359.5 degrees. That is, according to the reference azimuth an...

Embodiment 2

[0059] Embodiment 2: Step S130 specifically includes steps:

[0060] Step 1: Identify the cell A occupied by the UE and the neighboring cell B of the cell occupied by the UE according to the measurement report of the UE and the base station of the cell occupied by the UE.

[0061] The measurement report of the UE and the base station of the cell occupied by the UE carries a large amount of data. By analyzing these data and combining with the communication operator's database, the cell occupied by the UE and the neighboring cell B of the cell occupied by the UE can be identified.

[0062] Step 2: Obtain the location of the cell A occupied by the UE and the location of a neighboring cell B of the cell occupied by the UE.

[0063] The location of the cell A occupied by the UE and the location of the neighboring cell B of the cell occupied by the UE can be obtained from the communication operator's database, for example, the location (latitude and longitude data) of the cell can b...

Abstract

The invention provides a method and a system for measuring an azimuth angle of a cell base station antenna. The method comprises the following steps: obtaining a measurement report of UE and a cell base station occupied by the UE, obtaining a reference azimuth angle of the UE and the cell base station antenna occupied by the UE according to the measurement report of the UE and the cell base station occupied by the UE, carrying out XY axis vector summation on the reference azimuth angle of the UE and the cell base station antenna occupied by the UE to calculate an X axis azimuth angle vector sum and a Y axis azimuth angle vector sum, and calculating the azimuth angle of the cell base station antenna according to the X axis azimuth angle vector sum and the Y axis azimuth angle vector sum. The azimuth angle of the cell base station antenna is simply and accurately measured by rigorous data analysis and calculation.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and system for measuring the azimuth angle of a cell base station antenna. Background technique [0002] The LTE (Long Term Evolution, Long Term Evolution) project is the evolution of 3G, which improves and enhances the 3G air access technology, adopts OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) and MIMO (Multiple-Input Multiple -Output, multiple input multiple output system) as the only standard for its wireless network evolution. Under the 20MHz spectrum bandwidth, it can provide the peak rate of downlink 100Mbit / s and uplink 50Mbit / s.
