Description

Technical Field

[0001] This invention relates to the field of network management technology, specifically to a method and system for multi-agent collaborative identification of the root cause of batch ENodeB outages. Background Art

[0002] Traditional ENodeB fault location mainly relies on the experience of operation and maintenance experts and single-system log analysis, which presents three major challenges: 1. Excessive reliance on manual labor: It requires collaboration among experts from multiple fields such as transmission, wireless, and core network, with an average location time exceeding 4 hours; 2. Data silo effect: The data formats of systems such as network management, environmental monitoring, and performance are heterogeneous, and the alignment error rate of key indicators reaches 23%; 3. Lack of dynamic adaptation: Differences in the version / configuration of existing base stations result in more than 35% of faults not being able to match the preset detection template.

[0003] Existing technical shortcomings: 1. Linear and rigid process: The serial troubleshooting mechanism cannot dynamically switch detection paths, resulting in a false judgment rate as high as 27.6%; 2. Weak intelligent decision-making: The traditional rule engine only covers 68% of known scenarios and lacks a confidence verification mechanism; 3. Poor readability of results: The location report contains more than 80% technical terms, requiring front-line operation and maintenance personnel to translate them. Summary of the Invention

7. The system according to claim 6, characterized in that: In the problem rewriting module, the "problem rewriting agent" collects sentence information on the operator's query performance intent, covering a variety of common fault description patterns. Natural language processing technology uses a combination of lexical analysis, syntactic analysis, and semantic understanding to accurately extract keywords and identify user intent. The generated structured query statements can adapt to the data processing needs of subsequent modules.

8. The system according to claim 7, characterized in that: In the scene classification module, the "scene classification agent" uses a pre-trained classification model trained on a large amount of historical fault data. It classifies fault types through deep learning algorithms. When calling the historical case library, it uses a similarity calculation algorithm to comprehensively consider multi-dimensional information such as fault description, time, and location to match typical scenarios with a similarity greater than 85%. The matching results are then fed back to the path planning module to assist in generating a location path tree.

9. A system according to claim 8, characterized in that: In the root cause localization module, the "root cause localization agent" standardizes alarm data, performance indicators, and configuration parameters when constructing a multi-dimensional feature space to ensure that different types of data are comparable in a unified feature space. When using the sliding window algorithm to detect abnormal mutation points, it dynamically adjusts the window size and sliding step size according to the data characteristics. The improved Apriori algorithm filters and optimizes fault features when mining association rules to improve the accuracy and effectiveness of association rules.

10. A system according to claim 9, characterized in that: In the report generation module, when the "report generation agent" automatically generates an interpretable report using a template engine, it selects the appropriate report template according to different suspected root cause types. The report content includes fault description, diagnosis process, suspected root cause, and recommended measures information. When optimizing the readability of the output results using the BERT semantic matching model, technical terms are transformed into easy-to-understand expressions, and the transformed content is kept consistent with the original technical meaning. The generated report can be output in multiple formats, such as PDF and Word, to meet the needs of different users.
