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)
