Abstract

Provided is an inference-based home network error handling system and method capable of recognizing an error which occurs in a home network environment including a plurality of devices and services that are connected and executed, handling the error on the basis of an inference function, and providing support information used to recognize a cause of the error and handle the error to the user for the convenience of the user. Accordingly, errors are recognized according to devices, networks, and services, types of the errors recognized by applying inference rules set in advance and error handling rules are inferred, a result of the inferring is provided to the user, and error handling operations are performed according to a selection of a user.

Claims

1. An inference-based home network error handling system comprising:

a service error recognition module recognizing errors which occur in services of a home network system and collecting information on the errors;

a home network error recognition module recognizing errors which occur in networks of the home network system and collecting information on the errors;

a device error recognition module recognizing errors which occur in devices of the home network system and collecting information on the errors; and

an error handling management module inferring an error type and an error handling rule for solving the error on the basis of the information on the errors received from the service error recognition module, the home network recognition module, and the device error recognition module, guiding a result of the inferring for a user, and executing an error handling rule selected by the user.

2. The system of claim 1, wherein the error handling management module comprises:

an inference rule storage unit storing inference rules which are used to infer an error type and an error handling rule;

an error recognition information analyzer analyzing error information output from the error recognition modules and extracting information needed for error inference;

an inference engine inferring an error type and an error handling rule for solving the error from the information extracted by the error recognition information analyzer on the basis of the inference rules stored in the inference rule storage unit; and

an error handling execution manager guiding error occurrence information and error handling operations to the user and performing error handing according to a selection of a user in the providing operation on the basis of a result of the inferring of the inference engine.

3. The system of claim 2, wherein the error handling management module further comprises an error recognition rule storage unit storing error recognition rules to be used to perform error recognition by the service error recognition module, the home network error recognition module, and the device error recognition module.

4. The system of claim 2, wherein the service error recognition module recognizes an error of a service from service status information, whether or not the service is operated, and the usage of service execution resources extracted by monitoring each service provided from the home network system.

5. The system of claim 2, wherein the home network error recognition module recognizes an error of a home network from home network status information, network topology information, and network usage extracted by monitoring each network.

6. The system of claim 2, wherein the device error recognition module recognizes an error of a device from a data type and a data value extracted from status information provided from each device.

7. The system of claim 2, wherein, when the device error occurs, the error handling management module retrieves services used by the device, provides a list of the services to the user, and stops a service selected by the user.

8. The system of claim 2, wherein, when the home network error occurs, the error handling management module informs the user of a corresponding inferred error type and an error handling rule for handling the error and handles the error according to a selection of the user or a management rule.

9. The system of claim 2, wherein, when a service is to be reconfigured in order to continuously execute a service associated with the error type, the error handling management module informs the user of this and performs the service reconfiguration according to a selection of the user.

10. The system of claim 9, wherein, when the service reconfiguration is performed, the error handling management module provides a list of devices and data used by the service to the user and performs the reconfiguration according to a selection of the user.

11. An inference-based home network error handling method comprising:

setting inference rules for describing an inference range and standard for inferring an error type and a handling rule on the basis of error recognition information;

recognizing an error which occurs in a home network system;

inferring a type of the occurred error and an error handing rule for solving the error by applying the set inference rule; and

providing a result of the inferring to the user according to device errors, network errors, and service errors and performing error handling according to a selection of the user.

12. The method of claim 11, further comprising setting an error recognition rule for describing an error recognition range and an error recognition standard in order to recognize an error which occurs in the home network system before the recognizing the error.

13. The method of claim 12, further comprising, after handling the error, checking whether or not a service is to be reconfigured, when the service reconfiguration is needed, providing service reconfiguration information to the user, and performing the service reconfiguration according a selection of the user.

14. The method of claim 13, further comprising, when the service reconfiguration is not needed after checking whether or not the service is to be reconfigured, providing a list of services to be terminated in connection with the error handling to the user, and terminating a corresponding service.

15. The method of claim 13, wherein performing the service reconfiguration further comprises providing a list of devices and data used by the service and performing reconfiguration according to a selection of the user in order to perform the service reconfiguration.

16. The method of claim 11, wherein recognizing the error comprises recognizing an error of a service from service status information, whether or not a service is operated, and the amount of service execution resources used extracted by monitoring each service provided in the home network system.

17. The method of claim 11, wherein recognizing the error comprises recognizing an error of a home network from home network status information, network topology information, and network usage extracted by monitoring each network.

18. The method of claim 11, wherein recognizing the error comprises recognizing an error of a device from a data type and a data value extracted from status information provided from each device.

19. The method of claim 17, wherein, when the home network error occurs, performing the error handling comprises informing the user of a corresponding inferred error type and an error handling rule for handling the error and handling the error according to a selection of the user or a management rule.

20. The method of claim 18, wherein, when the device error occurs, performing the error handling comprises retrieving services used by the device, providing a list of the services to the user, and terminating a service selected by the user.

21. The method of claim 20, wherein performing the error handling further comprises, when a service is to be reconfigured in order to continuously execute the service associated with the error type, informing the user of this and performing the service reconfiguration according to a selection of the user.
