Description

Connection Management Simulation Method in Network Management System

The present invention relates to connection management simulation in a network management system. In particular, it is possible to interactively compose various types of response messages for a normal state or an abnormal state of a corresponding exchange system without directly interoperating a TMN agent with an ATM switching system. In addition, the present invention relates to a connection management simulation method in a network management system that enables the development and testing of a corresponding TMN agent more efficiently.

In general, systems related to network management are developed in various ways in structure and communication method according to companies and standards, and the importance of efficient management of them is gradually increasing, and heterogeneous systems developed by different manufacturers are efficiently The research on network management standards was conducted according to the requirements of management.

In addition, when a network element developer develops one network element such as an exchange system, the network element development company must also provide a network management function according to it. A network management standard called TMN (Telecommunication Management Network) was established.

On the other hand, TMN has the TMN Manager and TMN Agent models proposed by the Open System Interconnection (OSI) Network Management Scheme, which includes one or more management operations, namely connection management, configuration management, failure management, Manages performance management, etc., and requests management operation services from the TMN agent. The TMN agent manages management objects in the agent management area, performs management operation services requested from the TMN manager, or responds authorized from management objects. Notify the administrator of the message.

The conventional network management system includes a TMN manager 11, a TMN agent 12, an interface module 13, and an ATM switching system 14, as shown in FIG. 1. The TMN agent 12 receives a management command from the corresponding TMN manager 11 and delivers the management command to one interface module 13 for each management operation, and the transferred management command is transferred to the HMI by the interface module 13. After being converted into a (Human Machine Interface) instruction, it is transmitted to the ATM switching system 14 through an HMI server (not shown in the drawing), and the result is transmitted to the corresponding TMN manager 11 through the reverse path.

Meanwhile, in order to develop and test the TMN agent 12 of the network management system, it is necessary to interwork with the ATM switching system 14. However, in an environment where several departments (operation maintenance, call processing, operation system, TMN, etc.) related to the development of the corresponding ATM switching system 14 share and experiment with one ATM switching system 14, the TMN agent 12 tests. There are many cases where this is impossible.

For example, in the process of changing the operation system of the ATM switching system 14 or modifying the operation maintenance software, the TMN agent 12 cannot be developed and tested in conjunction with the ATM switching system 14.

As described above, in the conventional network management system, in order to develop or test a TMN agent, a command must be directly interworked with an ATM switching system, and then a response is received from the corresponding switching system. There was a problem that it takes a lot of time to develop or test the corresponding TMN agent because only the state can receive the response.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems as described above, and its purpose is to create a variety of response messages for the normal or abnormal state of the switching system without interworking with the ATM switching system, and deliver them to the administrator. In addition to testing the TMN agent regardless of the state of the ATM switching system, it is possible to develop the TMN agent more efficiently.

In order to achieve the above object, a feature of the present invention is a connection management simulation method in a network management system, assuming a switching system in a normal state, the method comprising: receiving a connection management command transmitted from an administrator; Creating a response message in a normal state corresponding to the received connection management command; It includes the process of delivering the written normal response message to the manager through the agent.

According to another aspect of the present invention, there is provided a connection management simulation method in a network management system assuming an abnormal state of a switching system, the method comprising: receiving a connection management command transmitted from an administrator; Receiving an error code of a necessary abnormal state; Analyzing the received connection management command to check whether parameters are required to create an abnormal status response message, and receiving the necessary parameters interactively; Creating an abnormal response message corresponding to the connection management command; It includes the process of delivering the created abnormal response message to the manager through the agent.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The network management system for the ATM switching system according to the present invention includes a TMN manager 21, a TMN agent 22, and a connection management simulator 23, as shown in FIG.

The TMN manager 21 instructs the connection management operation service to the corresponding TMN agent 22 in jurisdiction of the connection management operation on the managed object, and the TMN agent 22 issues a connection management command from the TMN manager 21. The response message transmitted from the connection management simulator 23 or from the connection management simulator 23 is transmitted to the TMN manager 21 side.

The connection management simulator 23 is an interface module between the ATM switching system and the TMN agent 22. The connection management simulator 23 analyzes the connection management command transmitted from the TMN manager 21 through the corresponding TMN agent 22 to output a corresponding response message. The response message is then sent to the corresponding TMN agent 22.

The operation of the network management system according to the present invention configured as described above will be described with reference to FIG. 3.

First, when the TMN manager 21 transfers the connection management command to the TMN agent 22 for the connection management test of the ATM switching system, the corresponding TMN agent 22 delivers the connection management command to the connection management simulator 23. do. Therefore, when the connection management command is received from the connection management simulator 23 (step S31), the connection management simulator 23 does not transmit the received connection management command to the ATM switching system, which is a response of the ATM switching system. As if the corresponding response message is created and transmitted to the TMN manager 21 through the TMN agent 22, the connection management simulator 23 receiving the connection management command sends the ATM switching system to a normal state or abnormality. Assuming the status, a corresponding response message is created (step S32).

If the connection management test is assumed to be in a normal state, the connection management simulator 23 writes a response message of a normal state corresponding to the received connection management command (step S33), and writes the created normal response message to a TMN agent (step S33). 22), the TMN agent 22 then delivers the normal response message to the TMN manager 21 (step S34).

However, if the connection management test is assumed to be in an abnormal state, the connection management simulator 23 receives an error code of the necessary abnormal state from the operator (step S35), and according to the received connection management command, various types of abnormalities. Since a response message exists, the connection management command is analyzed to determine whether a parameter is required to create a response message in an abnormal state (step S36).

At this time, if the corresponding parameter is required, after receiving the corresponding parameter interactively from the operator (step S37), an abnormal response message corresponding to the connection management command from the TMN manager 21 is created using the received parameter, If the parameter is not necessary, an abnormal response message corresponding to the connection management command from the TMN manager 21 is created (step S38), and then the generated abnormal response message is transmitted to the TMN agent 22, whereby the TMN agent 22 transmits the abnormal response message to the TMN manager 21 (step S39).

As described above, in the present invention, since the connection management simulator does not interwork with the ATM switching system, and performs the connection management test for the normal state or the abnormal state using the connection management simulator 23, The development environment of the irrelevant TMN agent 22 can be obtained. In addition, in the case of connection management tests for multiple exchange systems, each scattered ATM exchange system does not wait for normal operation, and the same response message obtained by interworking with the ATM exchange system in the connection management simulator 23. By creating a response message and passing it on, you do not have to wait for the switching system to operate normally.

As described above, the present invention creates and transmits various types of response messages to the administrator in the normal or abnormal state of the switching system without interworking with the ATM switching system, thereby irrespective of the state of the ATM switching system. It will be possible to test the TMN agent effectively.
