Network coverage problem identification method and device, and readable storage medium

Abstract

The invention discloses a network coverage problem identification method and device, and a readable storage medium, which are used for solving the technical problem that the test effectiveness and accuracy of a network coverage problem in the prior art are relatively low. The method comprises the following steps: obtaining MDT sampling data of an MDT sampling point and corresponding signaling data; determining MDT sampling points with missing longitude and latitude information, and performing position backfilling processing on the MDT sampling points with the missing longitude and latitude information according to the corresponding signaling data so as to estimate longitude and latitude information for the MDT sampling points with the missing longitude and latitude information; performingindoor and outdoor scene recognition on a terminal user according to latitude and longitude information included in the MDT sampling data to obtain a scene recognition result; and fitting and displaying the scene identification result and the network quality index information of each MDT sampling point on a rasterized electronic map to present a network coverage problem identification result.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for identifying network coverage problems, and a readable storage medium. Background technique [0002] Wireless network coverage is an important factor affecting network performance and user experience. Through accurate identification of network coverage quality problems, the main occurrence areas of various coverage problems can be identified, so as to fully understand the network coverage and guide network planning and optimization. The existing technologies for network coverage identification mainly include traditional drive test (ie, road test + CQT (Call Quality Test, call quality test)) and MR (Measurement Report, measurement report) + signaling. [0003] The traditional road test means that the road test engineers carry professional road test equipment (such as laptops, drive test software, GPS (Global Positioning System, Global Positio...

Problems solved by technology

In the MR+signaling method, since MR itself does not include latitude and longitude information, a third-party system is required to perform analysis, splicing and preprocessing of MR data and signaling data to obtain MR with latitude and longitude. The number of effective sample points is directly related to the ability of system parsing and splicing ; Some terminal manufacturers or OTT manufacturers encrypt user plane signaling data, and the platform cannot implement analysis and splicing, thereby reducing the effectiveness and objectivity of network problem identification; and the MR+ signaling method needs to collect user plane signaling data during user communication , so it only supports network problem identification based on data reported by user terminals in the connected state, and cannot identify the network coverage quality of users in the idle state

[0005] It can be seen that the current test methods for network coverage problems are not perfect, and there are technical problems of low effectiveness and accuracy in testing network coverage problems
