Phone number fraud detection method based on space-time network and graph algorithm

The invention belongs to the technical field of telecommunication fraud detection application, and particularly relates to a phone number fraud detection method based on a space-time network and a graph algorithm. The invention provides a phone number fraud detection method based on a space-time network and a graph algorithm, and aims to solve the problems that a vehicle-mounted goip fraud form relates to more data dimensions, and when a relational database is large in scale, multi-layer association relationship analysis is difficult to carry out, and association data are naturally connected together in a graph data form. According to the method, related numbers, tac, base stations and call data are processed into points and edges (the relation between the numbers, the tac, base station entities and the entities) in a graph, the numbers with the special incidence relation are explored in the form of the graph, then the numbers are further processed through a graph algorithm, and finally vehicle-mounted goip f
