Embodiments of the present invention provide a fault handling method, apparatus and system, and relate to the field of communications, where the method includes: detecting, by a lower-layer fault management system, a fault alarm status in a lower-layer service; obtaining, by means of query by the lower-layer fault management system, according to the fault alarm status and a service dependence relationship table stored in a system, an affected higher-layer service; sending, by the lower-layer fault management system, a fault notification message to a higher-layer fault management system corresponding to the affected higher-layer service; and determining, by the higher-layer fault management system, according to the fault notification message whether a higher-layer service in which a fault occurs needs to be handled. The present invention achieves an effect that when a fault occurs in the lower-layer service, the higher-layer fault management system may determine for the higher-layer service in which the fault occurs, according to the fault notification message, whether the higher-layer service in which the fault occurs needs to be handled, thereby reducing unnecessary waste of maintenance resources. |
