Embodiment Construction

[0033] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0034] The flow chart of an embodiment of the base station pitch angle detection method of the present invention is as follows figure 1 shown.

[0035] In step 101, the pitch angle information of the bill is obtained according to the bill data, and the bill data includes the connected base station number, sector number and time delay information. The calculation method of the bill pitch angle is as follows: figure 2 shown.

[0036] figure 2 Among them, L is the base station antenna, the height of the base station is H, A is the location of the user, and the time delay of the bill is T.

[0037] The unit of time delay can be 1 / 8chip. Assuming that the time delay is L, it can be converted into L*244 / 8 meters. According to the Pythagorean theorem, the virtual bill pitch angle of a given sector is calculated.

Abstract

The invention provides a method and a device for measuring a base station pitch angle and belongs to the communication field. the method comprises steps that a call detail record pitch angle is acquired according to the call detail record data and height of a base station antenna, and the call detail record data comprises a base station number, a sector number and the time delay; a state of an engineering parameter pitch angle is determined according to a pitch angle fitting trend line, the call detail record pitch angle and the engineering parameter pitch angle, and the pitch angle fitting trend line is a relation trend line of the call detail record pitch angle and an engineering parameter pitch angle of a corresponding base station sector. Through the method, the call detail record pitch angle can be acquired according to the call detail record data, the state of the engineering parameter pitch angle can be further determined according to the call detail record-engineering parameter pitch angle fitting trend line, the call detail record pitch angle and the engineering parameter pitch angle, so gradual manual field investigation or sensor mounting modes employed in the prior art are not needed, detection on the base station pitch angle can be realized through only the call detail record data, detection efficiency is improved, no hardware change is needed, and the method and the device are suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method and device for measuring base station pitch angles. Background technique [0002] The pitch angle of the base station antenna is an important parameter to determine its coverage. In daily network maintenance, the antenna feeder is loose due to natural reasons, misadjusted due to engineering reasons, or maintenance personnel have not entered the system after adjustment, which makes the pitch of the industrial parameter The discrepancy between the pitch angle and the actual pitch angle brings hidden dangers to network optimization, resulting in changes in sector coverage, network quality degradation, and poor user experience. Therefore, it is necessary to check the direction of the antenna feeder. [0003] The traditional method for checking the pitch angle of the antenna feeder is to climb to the top of the antenna tower by a professional, and use an inclinometer to confirm...
