CONSTITUTION: If a specific network management system request an interlinking service with an object network management system, a service operating environment of the specific network management system is analyzed through a network management environment setup manager(21). Interlinking service components are decided and prepared. The interlinking service components like application interface and communication interface are delivered to a corresponding network management system environment through a network management service delivery manager(22), to set up an actual interlinking environment between different kinds of network management systems. If the specific network management system request an interlinking service with the object network management system through the application interface and the communication interface, a logical or physical communication channel is set and released. The channel is requested for mutual transmission of management information and control information generated between the two network management systems through a network management communication resource manager(23). If application resource setup does not exist, an interlinking service performance environment is set up through the application interface. If application resource setup exists, the setup of network management interlinking serve is ended, to perform a corresponding network management application service.

The present invention relates to a method for processing interoperability between heterogeneous network management systems, and a technique for providing an interoperability processing method independent of an operation environment and a communication service environment of a heterogeneous network management system of a conventional non-standard and standard method.

In general, a network management service is composed of a set of functions and applications for exchanging and processing management information generated between network management systems represented by a manager system and an agent system in a distributed computing environment. The interoperability function plays a key role in the implementation of network management services in the implementation of network management service applications.

Heterogeneous network management systems Interoperability processing methods that depend on the network management system operation environment and communication service environment are related to the management operation environment and communication protocol environment of various network management systems to which developers are interoperable to implement network management service.
