Problems solved by technology

[0003] There are two main methods for wireless communication network optimization. There are two main methods for network quality assessment, one is the traditional drive test (DT) method, and the other is the MDT method, but both methods exist for solving the network quality evaluation of rail transit. Big drawback: the traditional drive test method mainly relies on manual operation, which has a long cycle and high cost
The tide of people in rail transit changes significantly, and the wireless environment changes greatly at different times. Traditional road tests cannot achieve full-time evaluation.
Since rail transit is often underground, user terminals cannot receive GPS signals, so AGPS-based MDT cannot be realized

Embodiment 1

[0074] see Figure 1-5 As shown, this embodiment provides a rail transit wireless network quality assessment method, including:

[0075] S1: Set multiple sampling points on the track line, and obtain the latitude and longitude of each sampling point;

[0076] Specifically, there are many methods for collecting the latitude and longitude of the track line, which can be purchased commercially or manually collected by means of a map API. For example: with the help of the coordinate extractor function of Baidu Maps, continuous sampling along a certain track line on the map to obtain the latitude and longitude coordinates of a certain track line. Since the track lines are usually irregular curves, the connection between adjacent latitude and longitude sampling points must coincide with the subway line, and the distance between adjacent sampling points should not be too large, usually no more than 100 meters. Through the collection of longitude and latitude of rail transit, a sequ...

Abstract

The invention provides a method and a device for evaluating quality of a rail transit wireless network as well as a medium. The method comprises the following steps of arranging a plurality of sampling points on a rail line, and acquiring longitude and latitude of each sampling point; segmenting the rail line according to a fixed-length segmentation mode to acquire a plurality of road section intervals, and coding each road section; determining coordinates of a cell switching point in a moving test process and a code of the road section interval to which the cell switching point belongs according to actual path measurement data of the rail line; acquiring S1MME interface signaling data of a full-quantity user, and recognizing a user taking the rail transit according to the S1MME interfacesignaling data; acquiring MR data of the user taking the rail transit; positioning the MR data of the user taking the rail transit to acquire the road section interval to which each piece of MR data reported when the user take the rail transit; and evaluating the network quality of the road section interval according to the MR data of each road section interval in order to automatically evaluate the quality of the whole rail transit line network.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method, a device and a medium for assessing the quality of a rail transit wireless network. Background technique [0002] China's urban rail transit construction has entered a period of rapid development. As of October 31, 2017, 29 cities in China have opened rail transit lines with a total mileage of 3,792.19 kilometers, 2,536 stations, and 128 lines. At the same time, mobile broadband networks The coverage rate of construction is increasing day by day, especially the 4G network has basically covered most of the areas. Therefore, the evaluation of network quality in rail transit is of great significance for operators to improve network quality and customer perception. [0003] There are two main methods for wireless communication network optimization. There are two main methods for network quality assessment, one is the traditional drive test (DT) method, and...
