摘要:

5G网络业务对基础设施的共用关系使得其业务故障逻辑更为复杂, 具体体现在业务故障间耦合关系的形成。其中抑制耦合作为一类特殊的业务故障耦合关系, 体现了业务故障间此消彼长、相互抑制的关联关系, 极大程度上影响着业务的运行情况。为了对抑制耦合影响下的5G业务故障进行分析, 本文基于对业务故障间抑制耦合关系的考虑, 提出了耦合故障树分析方法, 基于该方法本文实现了对抑制耦合关系影响下业务故障的解析评估。5G轮胎吊案例的分析与对比, 证明了本文所提方法的有效性。

Abstract:

The share of infrastructure between 5G network applications makes its fault logic more complicated, which is reflected in the forming of coupling relationships between application faults. Suppress coupling, as a special type of application fault coupling relationship, embodies the mutual suppression between application faults, which greatly affects the operation of applications. In order to analyze the 5G application fault under the influence of suppressing coupling, a coupled fault tree analysis method is proposed, which can analyse application fault under the influence of suppress coupling relationships. Through the analysis and comparison of 5G rubber-tyred container gantry crane (RTG) cases, the effectiveness of the method proposed is proved.

Key words: application fault analysis, suppress coupling, coupled fault tree, 5G rubber-tyred container gantry crane (RTG)
