AI Empowered Net-RCA for 6G
This addresses network fault management for 6G operators, but it appears incremental as it builds on existing RCA methods with AI enhancements.
The paper tackles the complexity and high maintenance costs of future 6G networks by proposing an AI-empowered framework for Network Root Cause Analysis (Net-RCA), demonstrating that it outperforms existing methods on synthetic and real-world data.
6G is envisioned to offer higher data rate, improved reliability, ubiquitous AI services, and support massive scale of connected devices. As a consequence, 6G will be much more complex than its predecessors. The growth of the system scale and complexity as well as the coexistence with the legacy networks and the diversified service requirements will inevitably incur huge maintenance cost and efforts for future 6G networks. Network Root Cause Analysis (Net-RCA) plays a critical role in identifying root causes of network faults. In this article, we first give an introduction about the envisioned 6G networks. Next, we discuss the challenges and potential solutions of 6G network operation and management, and comprehensively survey existing RCA methods. Then we propose an artificial intelligence (AI)-empowered Net-RCA framework for 6G. Performance comparisons on both synthetic and real-world network data are carried out to demonstrate that the proposed method outperforms the existing method considerably.
