PURPOSE: A MO(Management Object) information coinciding method in TMN(Telecommunication Management Network) is provided to reduce a communication load between a management agent block and a switching system by reading MO information of the switching system and updating MIB(Management Information Base) information only when MO information of the MIB and the MO information of the switching system are not the same with each other. CONSTITUTION: A management agent judges whether it is an initial state(S1). The management agent informs an NEIB(Network Element Interface Block) that initialization information is required(S2). The management agent judges whether initialization information is provided as a file from the NEIB(S3). When the initialization information is provided, the management agent stores the initialization information of MOs in an MIB(S4). The management agent maintains the MO information of the MIB in the previous state and requests entire connection information of MOs from the NEIB(S6). The management agent judges whether the entire connection information is provided as a file from the NEIB(S7). When the initialization information is provided from the NEIB, the management agent compares the provided connection information with connection information stored in the MIB, the switching system updates the different connection information(S8). The management agent is in a standby state(S9). The management agent judges whether a command for set-up or release of connection to a specific link the switching system is provided.(S10). When a command on the connection set-up or connection release is provided form a manager, the management agent provides the command of the manager to the switching system(S11). If a signal informing that corresponding command has been performed is not provided(S12), the management agent requests connection information on the corresponding link from the NEIB and the NEIB provides the request to a DBIB(Data Base Interface Block)(S13). The NEIB makes a file for the specific link connection information and provides it to the management agent, and upon receiving the file information of the NEIB(S14), the management agent compares the specific link connection information with specific link connection information stored in the MIB. If they are different, the management agent updates the specific link connection information with the link information received from the NEIB.
