Provided is a fault tracing system and method for remote maintenance. The fault tracing method includes detecting faults by receiving error events or fault diagnosis request messages, generating transactions for the detected faults, tracing the faults according to the transactions, and notifying a client terminal or user of the fault diagnosis results. Accordingly, it is possible to accurately trace a fault even in a home/building network environment complicatedly consisting of various resources.

Fault tracing system and method for remote maintenance

Provided are a home/building fault analysis system and method using a resource connection map log which compares and analyzes a previous integrated resource state and a current resource state using resource connection map logging information based on a standard resource management model when a fault is generated, provides state information of the resource in which information having high association with a fault resource is mainly changed, and performs an effective fault analysis and process by restoring to the previous resource state, as necessary. According to the prevent invention, when the fault is generated, a synthetic state of resources within a home/building as well as a state of an individual resource may be known from the resource connection map.

Home/building fault analysis system using resource connection map log and method thereof

A failure diagnosis method includes: generating a resource relationship map of resources to be managed on a network; and when a failure occurs in a certain service object within the network, extracting a topology relationship map from the resource relationship map by using the failed service object as a root node. The failure diagnosis method further includes searching a resource object caused the failure while checking related objects, starting from the root node in the topology relationship map.
