5G RSRP calculation method and system based on MR data

Abstract

The invention provides a 5G RSRP calculation method and system based on MR data. The method comprises the steps of obtaining historical MR data corresponding to MR sampling points in a to-be-detected area; obtaining a positioning parameter of an MR sampling point service cell, and generating a cell coverage layer on the map of the to-be-detected area; and generating an initial indoor grid and an initial outdoor grid, assigning the indoor attribute and the outdoor attribute of the MR sampling point, generating a 4G grid RSRP grid model, and calculating and predicting the 5G grid RSRP. MR data are used as a basis for analyzing 5G RSRP signal coverage, and data generated by actual use of a user can accurately reflect network problems; the 4G grid RSRP grid model is calculated through rasterization, the 5G RSRP is calculated based on the 4G grid RSRP grid model and the difference value between the 5G base station and the 4G base station, the data structure is simple, calculation is fast and efficient, the coverage effect is visual, and support is provided for 5G network deep coverage optimization.

Description

technical field [0001] The present invention relates to the technical field of 5G network optimization, in particular to a 5G RSRP calculation method and system based on MR data. Background technique [0002] 5G is a new generation of communication technology with advantages such as high speed, low latency, and high reliability. It is the cornerstone of the Internet of Everything and the digital economy. 5G supports the expansion of application scenarios from the mobile Internet to the Internet of Everything, becoming a new generation of high-speed, mobile, and secure information foundation. [0003] Since 5G uses high-frequency millimeter wave propagation, although it has the advantages of high speed, low delay, and high reliability, its propagation ability is poor, and its diffraction and wall penetration capabilities will be weakened; 5G base stations are expensive, and the cost of a single 5G base station on the market About 500,000 yuan, which is three times the price ...

Problems solved by technology

[0003] Since 5G uses high-frequency millimeter wave propagation, although it has the advantages of high speed, low delay, and high reliability, its propagation capability is poor, and its diffraction and wall penetration capabilities will be weakened; 5G base stations are expensive, and the cost of a single 5G base station on the market About 500,000 yuan, which is three times the price of ordinary 4G base stations; and to maintain the coverage of a 4G base station, it is necessary to invest in 100 5G base stations. It can be seen that the cost of 5G network construction and operation and maintenance is very high. Therefore, building a 5G network must not only satisfy users requirements, and to save costs as much as possible to avoid redundant deployment of 5G base stations

[0004] At present, it is necessary to measure the coverage capability of the 5G network by measuring the RSRP of 5G. The traditional method is to carry out manual testing on the spot near the base station by manually holding the mobile terminal device, and carry out network pulling / DT testing, which requires a lot of labor costs and time. cost, and the efficiency of manual collection is low, this method is difficult for towns and rural areas with low economic conditions; due to the large number of stations in the test area, it is difficult to make detailed and accurate corrections for a single station; in addition, the same station site Differences between 5G and 4G site installation heights, specific installation locations, feeder and connector losses, antenna configurations, and antenna pattern will all affect the evaluation results
