Title:
METHOD FOR PREDICTING AND POSITIONING ABNORMITY OF TRANSMISSION NETWORK BETWEEN CORE NETWORK AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2023/216457
Kind Code:
A1
Abstract:
A method for predicting and positioning an abnormity of a transmission network between a core network and a base station. The method comprises: classifying end-to-end troubleshooting process throughput data of a transmission network between the core network and a gNB, wherein the end-to-end process comprises five links, i.e., a server, the core network, a transmission link, the gNB, and UE as well as a PC connected to the UE; analyzing historical log data of each link to obtain an initial fault occurrence probability; moreover obtaining real-time data by means of current inspection and troubleshooting, and scoring each link according to the throughput rate; analyzing historical and real-time data to obtain real-time data that a fault is transferred to normality and the normality is transferred to a fault, and generating a rectangular set; then putting the rectangular set composed of three sets of data into an artificial intelligence model to analyze to obtain a future fault occurrence probability of each link; and generating a fault probability and scoring baseline by scoring the throughput during troubleshooting of each link in combination with the future fault occurrence probability of the link, comparing and analyzing, and troubleshooting and positioning a fault by means of an analysis result.
