Abstract

An integration agent device and its fault management method for a node including multi-layered devices are disclosed to effectively control a node including two or more communication devices of different layers and integrally processing relevant fault information. The integration agent device includes: one or more control and management modules controlling and managing one or more communications network devices by layer; and an inter-layer interworking processing module integrating and processing information of the communications network devices by using inter-layer interworking information, and notifying a management system accordingly, wherein the information of the communications network devices is transmitted through the one or more control and management.

Claims

1. A fault management method of an integration agent device that relays a node including multi-layered devices of one or more communications network devices each handling a different layer and a single management system, the method comprising:

a control and management step of controlling and managing the one or more communications network devices by layer with respective control and management modules, the network devices processing different communication layers;

a reception step of receiving fault information notified from the one or more communications network devices;

an integration and processing step of collecting the fault information and a relevant fault information of a lower layer, integrating the fault information and the relevant fault information, the integration and processing step processing device information into node fault information by;

determining whether or not the fault information has been generated from an uppermost layer;

if it is determined that the fault information has not been generated from the uppermost layer, recording the fault information in a temporary fault information and waiting for a pre-set time;

when the pre-set time elapses, extracting the fault information and relevant fault information of a different layer from the temporary fault information by using inter-layer resource relevant information;

if the fault information and the relevant fault information are not extracted from the temporary fault information, determining that the fault information has been integrated and terminating the integration and processing step, while if the fault information and the relevant fault information are extracted from the temporary fault information, processing the fault information and the relevant fault information into node fault information;

if it is determined that the fault information has been generated from the uppermost layer according to the determination result, referring to a relevant fault of a lower layer by using the temporary fault information and the inter-layer resource relevant information;

if there is no relevant fault of the lower layer upon reference, determining that the fault information has been created due to the fault of only a corresponding communications network equipment and processing it into node fault information; and

if there is a relevant fault of the lower layer upon reference, determining that the fault information has been created due to a fault of a different layer, extracting information of the relevant fault, and processing it into node fault information; and

a notifying step of providing the node fault information to the single management system.
