[0002]

2. Description of the Related Art In recent years, a network management device for managing various devices connected to an information network in which a plurality of communication devices and information processing devices are interconnected, and an integrated network management device interconnected with the network management device A network management system for centrally managing a network has been constructed by exchanging management information on management objects existing in various devices between the network management system and the other devices.

[0003] This network management system is a so-called management system for making the communication network easy to use for the user, always providing stable and good service, and operating efficiently.
Alternatively, as an operation, TMN (Telecommunicat
ion Management Network) is known. This network includes intelligent networks and NI
Devices and systems used in networks, such as SDN and B-ISDN, have increasingly complex and sophisticated functions and are controlled by software. In addition, to improve the efficiency of the telecommunications business, local areas are unmanned, maintenance and operation of facilities are centralized in one place, multiple vendors are increased, and conditions for maintenance, operation and management are unified and sophisticated. -Quick response to diversification is also required.

[0004] This communication management network (TMN)
When an operator exchanges information for maintenance, it is necessary to define the network and negotiate procedures in common, and standardize the terms used.In order to define and describe the network maintenance and procedures, an object-oriented definition method is used. It is effective. On the premise of this, the TMN standard interface is recommended as the OSI (Open Systems Interconnection) management standard of the International Standards Organization for terms (messages) and exchange methods (protocols) to be exchanged between systems. A Q interface for exchanging management information between the operation system and the communication device, an F interface for exchanging information between the operation system and the workstation, and an X interface for exchanging information between different networks are scheduled.

[0005]

Under such circumstances, as one of the network management systems (NMS), the integrated network management system integrates a plurality of managed networks having individual network management systems. It is used as a management system. Each managed network has an individual management interface, and when these are integrated, it was necessary to add a function so that the integrated network management system could decode multiple individual network management interfaces. .

Therefore, the prior art has the following problems.

[0007] The first problem is that when another managed network is added to a managed network having an individual management interface as an existing facility, a function for decoding the individual management interface is added to the integrated management system body. Therefore, the scalability of the management target is poor, and when a management target network having a new management interface is added, the number of development steps and the time required for development are increased.

[0008] The second problem is that if the management interface is changed, it is necessary to remodel the integrated network management system itself. Therefore, if the individual management interface is changed, it cannot be easily handled. It is in. In this way, the number of man-hours for remodeling the integrated network management system and the period required for remodeling due to the change of the management interface of the network to be managed are increased.

SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to construct an integrated network management system and to reduce the man-hour and time required for the system to be revised even when a new network to be managed is added. .
