Problems solved by technology

[0005] 1. The provincial company of the communication operator cannot review the accuracy of the measured data
[0006] Since the single-site verification report is provided and filled out by the branch of the communication operator, the accuracy and authenticity of the data provided cannot be audited by the provincial company
The provincial company cannot conduct on-site verification, but can only verify the difference between the planned data and the provided measured data. The coverage effect of the test is also judged by humans whether it is reasonable, and there is no real comparison with the planned effect
Therefore, the provincial company cannot audit the accuracy of the underlying data
As a result, the provincial company's control cannot truly "begin with the end in mind", technically it cannot be directly planned, nor can it perform benchmarking audits on measured data, and it cannot truly verify and determine the relationship between measured data and planning data. difference
[0007] 2. There are defects in the random inspection method of communication operators and provincial companies
However, in view of the workload, the provincial company can only conduct random inspections, so it cannot control the overall situation to a certain extent
Therefore, there is a problem of excessive randomness in controlling local problem points
[0009] 3. At present, provincial companies of communication operators usually use manual methods for acceptance and audit analysis of each base station. The audit efficiency is low and the audit coverage is small.
[0010] To sum up, traditional quality control generally refers to controlling the construction quality of the LTE network through single-site verification by the branch of the communication operator and sampling inspection by the provincial company of the communication operator. discrepancies, and work-intensive flaws
It can be seen from this that the base station single-site verification cycle is long and the efficiency is low, and the problem of base station coverage performance cannot be quickly and efficiently located.

Abstract

The invention discloses a positioning method for a base station coverage performance. The method comprises: according to basic data, a three-dimensional map, and a ray tracking model, a cell simulation environment is established; the ray tracking model is corrected, a cell simulation environment corresponding to the corrected ray tracking model is obtained, and a cell antenna height is checked based on the three-dimensional map; RSRP sweep-frequency data are measured practically by using the cell antenna with the checked cell antenna height, rasterization calculation is carried out according to the cell simulation environment to obtain cell simulation RSRP data, and the cell simulation RSRP data and the RSRP sweep-frequency data are checked; and according to a checking result of the cell simulation RSRP data and the RSRP sweep-frequency data, whether the cell is a suspected problem cell is determined. In addition, the invention also discloses a positioning system for a base station coverage performance.

Description

technical field [0001] The invention relates to base station construction technology in the field of mobile communication, in particular to a base station coverage performance positioning method and system. Background technique [0002] Due to the complexity of the wireless network environment, it brings great difficulties to the quality control of the base station coverage performance in the Long Term Evolution (LTE, Long Term Evolution) technology. Therefore, how to quickly and effectively collect wireless network quality indicators, discover problems existing in LTE network construction, and solve the problems are the focus and difficulty of quality control work in the process of LTE network construction. [0003] In the process of LTE network construction, the construction quality of the network determines whether the acceptance link can be put into operation immediately. At present, the way to control the quality of network construction is: single-site verification rep...
