The command input unit 11 of the operator input / output processing unit 10 connected to the graphic display device used by the operator is shown. When the operator operation command is input through, the authority search unit 22 of the device resource management unit 20 retrieves the operator and the authority for the command. ---- first step (S1);

If the authority is found to be a command that is not authorized, a rejection message is configured and transmitted to the operator through the operator input / output processing unit 10 (as part ⓐ). If the authority is permitted, the command analyzer 23 is executed. Analyzing the protocol through which the operator command is to be performed (second step S2);

The operation behavior according to the analyzed command is recorded in the database. ---- step S3;

Subsequently, it is determined whether the command is a database search command in the analyzed command, and if it is a data search command, the data is searched through the database control unit 25 and transmitted to the operator (as part ⓐ). ---- fourth step (S4);

If the above is not a database search command, a response waiting message is configured and then a transmission target protocol is set among a plurality of broadband access devices. ---- fifth step (S5);

Then, it is checked whether the protocol set in the above is MML, TMN, or SNMP (sixth step (S6)) to perform a command corresponding to each step. If the MML, the operation command input above through the MML processing unit 30 After converting to MML, error check is performed and if there is an error, reconversion is performed. ---- seventh step (S7);

If it is confirmed that the TMN, the TMN processing unit 40 converts the operation command to the TMN management service, searches for the TMN MIB, and extracts the management object to configure CMISE parameters. ---- eighth step (S8);

If the check result is SNMP, the SNMP processing unit 50 converts the operation command into an SNMP management service, searches for the SNMP MIB, and extracts a management object to configure SNMP parameters. ---- ninth step (S9);

When the messages are configured through the steps S7, S8, and S9, the communication protocol processor 60 establishes a communication protocol connection to be transmitted, and each protocol controller 61, 62, 63, and the communication transmitter and receiver (64). Send a message to the agent in the corresponding broadband access device through step ---- the tenth step (S10);

When the operation message is sent from the integrated operation management apparatus 1 of the present invention through the above process, the corresponding broadband access device performs the processing according to the message requirements, and then receives the response message when the response message is transmitted. The process of processing is explained with reference to FIG.

Search the receive queue (not shown) in the communication transmitter / receiver 64 for information received through the agents of the respective broadband access devices, and if the message exists in the receive queue, determine which protocol the message corresponds to. do. ---- first step (T1);

As a result of the determination, if the protocol corresponds to MML, the MML processing unit 30 extracts the MML from the received message and performs an error check. If there is no error, the MML is converted into an operation message. Retransmit (to ⓑ in Figure 8) to the broadband access device that sent the message. ---- second step (T2);

As a result of the determination, if the protocol corresponds to the TMN, the TMISE processor 40 extracts the CMISE parameter and the TMN management service from the received message, and then converts the TMN management service into an operation message. ---- third step (T3);

If the determination result indicates that the protocol corresponds to SNMP, the SNMP processing unit 50 extracts the SNMP parameter and the SNMP management service from the received message, and then converts the SNMP management service into an operation message. ---- fourth step (T4);

The message converted through each process (T2, T3, T4) is searched to determine whether there is a message related to an alarm / event in the message. ---- fifth step (T5);

If the determination result exists, extract the alarm / event message and store it in the database. If the determination result does not exist, the message is analyzed and the operation command execution result is recorded. ---- sixth step (T6);

The operator input / output processing unit 10 sets an environment for configuring a batch screen so that the operator can receive each processed message, and then performs a screen process to transmit the image to the graphic display device. ---- seventh step (T7);

As described in detail above, the present invention enables an operator to operate independently of the operation management protocol of each broadband access device by using one operator output interface from an operator's point of view in order to control a plurality of broadband access devices. Since there is no need to operate the operation management device according to each protocol type, cost reduction and facility area can be reduced, and command response or event / alarm message is received through data communication network regardless of the location of each broadband access device. Therefore, the result is immediately screened as a single operator graphic, and the information is stored in a database so that it can be collectively operated in one place, thereby maximizing the convenience of operation.
