Abstract

There are provided a fault processing system and method for quickly and accurately diagnosing a fault and autonomously processing the fault, based on interdependencies between various devices, networks, systems, and services in home network environments, the method including: establishing fault detection rules for detecting faults belonging to respective fault types defined for each situation by classifying faults occurring in the home network environments, fault diagnosis rules for diagnosing a fault type of a fault, and fault processing rules defining a method of solving a fault for each fault type; collecting state information of devices, networks, services, and the system in the home network environments and detecting a fault based on the fault detection rules; diagnosing the fault type of the detected fault by applying the fault diagnosis rules; and processing the detected fault based on the fault processing rules according to the diagnosed fault type.

Claims

1. An autonomous fault processing method for home network environments, the method comprising:

establishing fault detection rules for detecting faults belonging to respective fault types defined for each situation by classifying faults occurring in the home network environments, fault diagnosis rules for diagnosing a fault type of a fault, and fault processing rules defining a method of solving a fault for each fault type;

collecting state information of devices, networks, services, and the system in the home network environments and detecting a fault based on the fault detection rules;

diagnosing the fault type of the detected fault by applying the fault diagnosis rules; and

processing the detected fault based on the fault processing rules according to the diagnosed fault type.

2. The method of claim 1, wherein the fault type is defined by a fault cause, a fault state, and a recovery method.

3. The method of claim 2, wherein the fault type comprises one or more of analog faults, digital faults, device misconfiguration, network misconfiguration, service misconfiguration, resource conflicts, and context conflicts.

4. The method of claim 2, wherein the fault processing rules comprises one or more of a context, a resource, network reconfiguration, rollback, reset/restart, notify, remote recovery, and connection to an offline after service center.

5. An autonomous fault processing system for home network environments, the system comprising:

a storage storing fault detection rules for detecting faults occurring in the home network environments, fault diagnosis rules for diagnosing a fault type defined by classifying the faults for each situation, and fault processing rules defining a method of processing a fault for each fault type, and state information collected from the home network environments;

a fault detection module collecting the state information on devices, networks, services, and the system in the home network environments and detecting and reporting a fault based on the fault detection rules;

a fault diagnosis module diagnosing the type of a fault detected by the fault detection module by applying the fault diagnosis rules; and

a fault processing module processing the detected fault by applying the fault processing rules according to the fault type diagnosed by the fault diagnosis module.

6. The system of claim 5, wherein the fault type is defined by a fault cause, a fault state, and a recovery method.

7. The system of claim 6, wherein the fault type comprises one or more of analog faults, digital faults, device misconfiguration, network misconfiguration, service misconfiguration, resource conflicts, and context conflicts.

8. The system of claim 6, wherein the fault processing rules comprises one or more of a context, a resource, network reconfiguration, rollback, reset/restart, notify, remote recovery, and connection to an offline after service center.

9. The system of claim 5, wherein the fault detection module comprises:

one or more of fault detectors collecting device state information, system state information, and home network state information, respectively; and

a fault message output unit analyzing the state information collected by the one or more of fault detectors according to the fault detection module and generating a fault message when there is detected a fault.

10. The system of claim 5, wherein the fault diagnosis module comprises:

a condition combiner combining the state information collected by the fault detection module when the fault is reported by the fault detection module; and

a fault type determiner determining the fault type by analyzing the state information combined by the condition combiner according to the fault diagnosis rules.

11. The system of claim 5, wherein the fault processing module comprises:

a fault processing rule interpreter reading and interpreting the fault processing rule according to the fault type diagnosed by the fault diagnosis module from the storage; and

a fault processing rule executor executing the fault processing rule interpreted by the fault processing rule interpreter.

12. The system of claim 11, wherein the fault processing module displays a cause and a recovery method of the fault according to a diagnosis result of the fault diagnosis module.

13. The system of claim 12, wherein the fault processing module displays fault information comprising one or more of home network state information collected by the fault detection module, after processing the fault, a fault type code, a fault cause, and a fault recovery method.
