The invention relates to an information and communication business influence analysis model establishment method and system. The method comprises steps that when a determination basis is equipment, anequipment table and a gateway alarm are retrieved according to a name of designated equipment; whether the alarm information exists is determined, if not, having no routing is determined, if yes, theequipment information and the alarm are extracted, relevant routing is extracted according to the routing record information, and whether routing exists is determined for another time; if yes, the routing information is processed in a circulation mode, equipment series connection of a business circuit is sequentially carried out, the gateway alarm is retrieved according to equipment series connection, alarm and performance related to each piece of equipment are extracted, and data is integrated to generate routing alarm output. The method is advantaged in that a fault problem of an information communication system can be determined through the equipment direction or the business direction, the corresponding business circuit alarm is generated, the relevant equipment is marked through topological graphs for representation, the test scope and the coverage area of end-to-end equipment can be expanded, and active fault detection processing is realized.
