随着5G移动网络的全球推广，5G移动网络故障正成为常态。如果无人看管，它们会影响移动用户体验和应用程序的正常运行。在这项工作中，我们描述了SEED，它为5G故障诊断和处理提供了一种新的基于SIM的解决方案。Seed通过利用当前标准化的5G错误代码和决策树/在线学习算法来推断故障原因。它还采取相应的多层重置/重做操作(重置协议操作、刷新过时的配置、重新加载配置文件等)。一旦推断出故障原因。Seed在其快速部署的设计中考虑了操作员的观点。种子设计在5G标准框架内工作，不需要更改设备固件或基础设施硬件。我们的评估证实了种子的生存能力。
Failures in 5G mobile networks are becoming the norm with the ongoing global rollout. If left unattended, they affect mobile user experiences and the proper functioning of applications. In this work, we describe SEED, which offers a novel SIM-based solution to 5G failure diagnosis and handling. SEED infers failure causes by exploiting current standardized 5G error codes and decision-tree/online learning algorithms. It further takes corresponding multi-tier reset/redo actions (reset protocol operations, refresh outdated configurations, reload profiles, etc.) once the failure cause is inferred. SEED takes the operator's perspective in its design for fast deployment. SEED design works within the 5G standard framework and does not require changes on the device firmware or infrastructure hardware. Our evaluation has confirmed the viability of SEED.
