Problems may arise. In such an environment, the existing network must be reflected in the communication network management unit 103 by the local management unit 105 operating in the NON_TMN environment. However, in the case where the operation and management configuration of the network management equipment is as described above, the case where the operation of the local management unit 105 of the conventional NON_TMN environment is reflected in the TMN environment has not been found in the literature or recommendation. As network management spreads rapidly, such problems are raised, and methods for reflecting the operation of the local management unit 105 of the existing NON_TMN environment to the TMN environment have been raised.

By reflecting changes in network configuration equipment generated during the operation of the local management unit in the NON_TMN environment to the TMN environment through a single interface, the overall system operation efficiency can be improved without affecting the operation of the TMN management agency in the past. The present invention provides a method and system.

The present invention for carrying out the above object is required to communicate with the local management unit, the communication network management unit, the message for the external communication of the network configuration equipment with the switch and the network configuration equipment with the local management unit in a system equipped with a switch. A message conversion unit for converting a string message defining information, and a transmission / reception message with a block inside a network constituting device in relation to initialization at the communication network management unit and the exchange, and for a CMIP message between the message conversion unit and the communication management unit.

Command execution by the communication network management unit 101 is transmitted to the TMN network manager from the TMN GUI or other network manager system in the command processing from the network operator. The communication network management unit 101 analyzes the received command and transmits a CMIP command to the communication network management agent unit 203 to obtain information required by a network operator or another network manager system. The management agent process 117 existing in the network management agent 203 transmits a request of the network operator to the managed object thread 118 using the internal message. The management object thread 118 analyzes the received internal message, processes it if it can be processed using the internal management information database, and transmits it to the communication network management agent 203 through the management agent process 117, and internally. When it is impossible to process the management information database information or when it is necessary to communicate with the network configuration equipment, the message conversion unit 200 converts a message as shown in the example of FIG. 4 by using the asynchronous processing routine of FIG. And wait to process the next message after transmission to the transmission / reception block. The message change of the message conversion unit 200 and the gateway interface 111 in the transmission / reception block receive the message transmitted from the management object thread 118. Send the message to the message analyzer 113 to convert the message type necessary for communication with the network configuration equipment and then send the message The controller 115 transmits the response from the network component to the network component via the receiver 115. The message processing unit 116 receives the response from the network component and converts the message from the message analyzer 113 into the boardcasting of the gateway interface 111. It transmits to the managed object thread 118 and the local management unit 105 through the function. The management object thread 118 waiting to receive the message transmitted from the gateway interface 111 by scheduling through the management agent process 117 through the process as shown in FIG. 5 by using the CMIP protocol to the communication network management unit 101. Is sent. The communication network manager 101 creates a message required by the network operator using the received CMIP message and data stored therein and delivers the message to the network operator to confirm the information requested by the network operator through the TMN GUI. When an abnormal situation occurs in the network configuration equipment, the processing in the TMN environment may be performed by receiving a message notified when an abnormal situation occurs in the network configuration equipment by the message conversion unit 200 of the message conversion unit 200 and the reception message processing unit 116 in the transmission / reception block.

5 is a flowchart illustrating processing of a TMN message and a NON_TMN message through an asynchronous method of the management object threads 118 existing in the network management agent 203.

The management object thread 118 is largely divided into a reception message processing unit Rx and a transmission message processing unit Tx. The received message processing unit Rx mainly prepares a message type capable of communicating with the network management equipment by using a request message from the communication network management unit 101 and an internal management information database. The transmission message processing unit (Tx) is a response to the request of the TMN management unit 101 and a notification caused by an abnormal situation of the network configuration equipment, by the request of the local management unit 105 present in the NON_TMN environment. The command is processed through a sequential procedure using the fields of each C_CODE of [4-2] among the common message types of FIG. 4. FIG. 5 shows one continuous processing algorithm of the receiving message processing unit and the transmitting message processing unit. . 5 waits for a network response or a notification message to be received through a network request message through an internal routine of step (5a), and checks whether it is a network response message in step (5c). From step 5e), it is a response message by the request of the TMN management unit 101, and the notification message date and time in step (5c) is a notification that occurs due to an abnormal condition of network configuration equipment in step (5d) and local in the NON_TMN environment. This is a response message to a command by a request of the management unit 105 and a response to a notification caused by an abnormal situation of the network configuration device and a change of state of the network configuration device due to a request of the local management unit 105 present in the NON_TMN environment. Therefore, since the network management system of the network equipment is integrated into a single TMN environment, there is no change in the systems of the TMN environment.

As described above, in order to solve the inconsistency of information generated in the environment where the local manager of the conventional NON_TMN environment and the manager system of the TMN environment coexist, asynchronous structure and integrated message conversion by scheduling each processing block of the TMN management agent system By using the block, the state change generated by the operation of the local manager in the NON_TMN environment is reflected in the TMN environment through one interface, without affecting the structure of the TMN management agent system and the performance of the TMN management agent system. There is an advantage in pursuing the efficiency of the overall system operation.
