Description

Fault information management system and management method in communication network {A Management of Fault Information in Telecommunication Network}

The present invention is in the failure management function of the communication management network that the agent (manager) reports to the manager, when the agent's failure information is lost due to communication failure between the manager and the agent for the manager's failure information recovery The present invention relates to a failure information management system and a management method for monitoring a reception status of failure information, detecting occurrence of an error, and recovering from failure information.

In the conventional network management system, because a new failure message generated in the device is lost in the middle due to a communication failure between the manager and the agent, or the release message is lost, the administrator may deliver the wrong failure information to the operator, There was a problem that caused errors in the operation and maintenance of the device to reduce the reliability of the device. Accordingly, there is a need for a technique for detecting a mismatch in a failure message due to a communication failure between an administrator and an agent, and automatically recovering the mismatch.

Accordingly, the present invention provides an error information management system in a communication network that enables reliable maintenance of an operator by automatically detecting a communication error between an agent and a manager of a communication management network and automatically recovering an error information that occurred. The purpose is to provide a management method.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a network failure information management system according to the present invention.

In general, a communication network failure information management system receives a failure occurring in the communication device 100 and converts it into a failure message form and reports the manager 200 to the manager 300 and the failure message received from the agent 200. Manager 300 for processing, and operator computer 400 in charge of the maintenance of the entire system.

The communication device 100 is responsible for the function of performing communication by loading the equipment dedicated to communication, and reports a failure to the agent 200 when a failure occurs in the loaded equipment. In addition, if the current failure does not recover within a certain time, the same failure occurs periodically.

The agent 200 receives a failure occurring in the communication device 100, converts it into a failure message form, and continuously reports to the manager 300. The configuration of the agent 200 does not require any configuration and function other than the failure transmitter 210 to assemble the failure in the form of a message to the manager 300.

The manager 300 performs a function of processing a failure message received from the agent 200. The configuration of the manager 300 includes a failure receiver 310 for receiving a failure message transmitted from the agent 200, a failure handler 320 for properly processing the received failure message, and a failure storage device for storing the processed failure message. 330, a failure reporter 340 for reporting the processed failure to the operator computer 400, a reception status monitor 350 for monitoring a communication failure with the agent 200, error due to loss of a failure message due to a communication failure The fault recovery unit 360 automatically recovers the fault information that has occurred, and the recovery information storage unit 380 for storing a fault for a predetermined period of time after the normal return of the communication state for fault recovery.

2 is a flowchart illustrating error information error detection according to the present invention.

The agent 200 and the manager 300 continuously transmit and receive a failure message through the failure transmitter 210 and the failure receiver 310. If a communication failure occurs between the agent 200 and the manager 300, the communication failure is detected by the reception state monitor 350.

The reception state monitor 350 performs the reception state initialization 352 and the recovery state initialization 353 to set up that the current transmission / reception state is normal and no recovery is required. Then, the reception state monitor checks whether the reception state with the fault transmitter is normal (354) and continues to monitor the reception state if it is normal. If the reception state is abnormal, the recovery state is set (355) and the reception state is monitored. It continuously monitors whether the reception state is normal (356) and if it is abnormal, continuously monitors the reception state. If the reception state is returned to the normal state, it is determined that an error has occurred in the failure information due to the failure of the failure message, and the failure recovery request 357 calls the failure recovery unit 360 to perform recovery.

3 is a flowchart of error information error recovery according to the present invention.

The failure recovery device 360 called by the failure recovery request 357 performs time allocation according to a failure level (362). The time allocation for each fault class uses a communication device generation cycle that repeatedly generates the same fault message for each fault class. For example, in case of emergency disability level, the period of occurrence is 15 minutes, in case of major disability level, the frequency of occurrence is 30 minutes and in case of mild disability level, the frequency of occurrence is 60 minutes. The failure information stored in the failure storage unit 330 of the manager 300 is sorted by failure level (363). Next, iterative processing 364 corresponding to all failure levels is performed.

The iterative process 364 calculates the difference between the current time and the reception state normal return time (365). The calculated result is compared with the time set by the time class for each disability class (366). If the time set by the time class by the disability class is large, the presence of corresponding i-class disability information among the fault information in the fault storage unit 330 is determined. Check (367). As a result of the check, if there is the failure information of the corresponding grade, the failure information of the corresponding grade is extracted (368), the failure information and the recovery information in the recovery storage (380) by comparing and searching (369), the same communication device 100 In step 370, it is determined whether there is a failure message that has occurred. As a result of the check 370, if there is a failure message occurring in the same communication device, the contents of the failure message are applied (371). If there is no failure message occurring in the same communication device, it is determined that the lost failure message is a failure recovery message. The fault of the corresponding fault information is released (372). The above process is performed for all disability information having the corresponding level (373).

After the recovery of all the failure information existing in the failure store through the above process, the manager 300 reports the failure error recovery contents to the operator computer 400 through the failure reporter (340).

According to the present invention as described above, if the information reporting of the agent is lost due to communication failure between the manager and the agent, it is possible to automatically detect the inconsistency and recovery of the inconsistency for the administrator's information recovery, so that the information inconsistency It automatically detects and recovers automatically, enabling reliable maintenance of the operator. In addition, the present invention does not require the buffering of the message according to the communication failure in the agent used in the conventional method, it is possible to inexpensive development of the agent because the buffered message is not transmitted collectively when the communication failure is terminated.
