Cross-network-level topological relation mining method and device, equipment and storage medium

The invention relates to a cross-network-level topological relation mining method and device, computer equipment and a storage medium, and relates to the technical field of data processing. The method comprises the following steps: grouping alarm data in two network hierarchies with a root cause relationship in a communication network based on a time dimension and a space dimension to obtain at least two alarm groups; one alarm group comprises one piece of root alarm data and at least one piece of cause alarm data; the alarm data comprises a network element field used for indicating network element equipment generating the alarm data; constructing a frequent pattern tree based on the occurrence frequency of each alarm pair corresponding to the at least two alarm groups; and mining a network element topological relation in the two network hierarchies based on the frequent pattern tree. Through the method, the complexity of network element topological relation mining can be reduced, understanding is facilitated
