METHODS FOR MANAGING THE STATE OF ATM SWITCH BY TELECOMMUNICATONS MANAGEMENT NETWORK}

The present invention relates to a state management method of an asynchronous delivery mode switch by a communication management network system having a Telecommunications Management Network (hereinafter referred to as "TMN") manager system and TMN management agent system.

Conventionally, when the Asynchronous Tranfer Mode (hereinafter referred to as "ATM") exchange is down, the state of the ATM exchange is not reflected to the agent, but only the down of the ATM exchange. Only the result was delivered to the Manager through a separate channel, not the Common Management Information Protocol (hereinafter referred to as "CMIP").

Therefore, when the ATM switch is restarted in the related art, specific hardware resources of the ATM switch may be abnormal, but the management information base of the management agent does not reflect the abnormal state assuming that all hardware resources of the ATM switch are in an initial normal state. In the case of the manager's actions, the ATM's performance was refused, and during normal operation, there was a problem that the actual state of the ATM switch and the management agent's recognition state were different for various reasons.

Accordingly, the present invention has been made to solve the above problems, and when the ATM switch is down or restarted, the TMN management agent system is in a state of the management object instance stored in the Management Information Base (MIB). By reporting to the TMN manager system properly reflecting the fact that the ATM switch is down or restarted, the TMN operator can accurately recognize the status of the remote ATM switch, and the state stored by the TMN manager agent system and the actual ATM switch during normal operation. The purpose of the present invention is to provide a state management method of an asynchronous delivery mode switch by a communication management network system capable of managing an ATM switch by auditing, comparing and verifying the state of the switch.
