📝 摘要(中文)

根因分析(RCA)在电信网络运营中至关重要,但在现代5G和新兴6G网络中,由于复杂的跨层依赖,诊断性能下降仍然具有挑战性。尽管大型语言模型(LLMs)在推理和知识整合方面展现出良好能力,但直接应用于电信RCA常导致幻觉、不稳定推理和与结构化网络证据不一致。本文回顾了电信RCA的演变,提出了一种结构化推理框架,将诊断推理与电信特定证据和领域知识对齐。实验结果表明,该框架在两个5G RCA数据集上显著提高了诊断准确性和决策一致性。

📄 摘要(原文)

Root cause analysis (RCA) is a critical task in telecom network operations, but diagnosing performance degradations in modern 5G and emerging 6G networks remains challenging due to complex cross-layer dependencies. While large language models (LLMs) offer promising capabilities for reasoning and knowledge integration, directly applying vanilla LLMs to telecom RCA often leads to hallucination, unstable reasoning, and poor alignment with structured network evidence. This work first reviews the evolution of telecom RCA from rule-based and machine learning (ML) approaches to emerging LLM-enabled techniques, and provides an overview of recent paradigms, including structured reasoning, retrieval-augmented knowledge grounding, agentic orchestration, and verifiable reasoning. Building upon these insights, we propose a structured reasoning framework for LLM-enabled telecom RCA that aligns diagnostic reasoning with telecom-specific evidence and domain knowledge. The proposed approach first organizes heterogeneous network telemetry into canonical contexts, and then enforces decision-path reasoning during diagnosis, and finally generates evidence-grounded explanations for reliable fault identification. Experimental results on two 5G RCA datasets, TeleLogs and TelecomTS, demonstrate that the proposed framework consistently improves diagnostic accuracy and decision consistency compared with baseline techniques. These cross-dataset results highlight the importance of structured reasoning design for practical LLM-based RCA systems in next-generation telecom networks.
