1. An inference-based home network error handling system for handling an error in a home network system that includes a device, a network and a service, comprising: three error recognition modules, including: a service error recognition module recognizing a first irregularity that has occurred in services of the home network system, and collecting information on the first irregularity; a home network error recognition module recognizing a second irregularity that has occurred in networks of the home network system, and collecting information on the second irregularity; and a device error recognition module recognizing a third irregularity that has occurred in devices of the home network system, and collecting information on the third irregularity; and an error handling management module inferring an error type, using the collected information, that indicates whether a recognized one of the first, second and third irregularities is an error in the device, an error in the network or an error in the service, and inferring error handling rules for correcting the inferred error type, guiding a result of the inferring for a user, and executing one of the error handling rules selected by the user.
