3A and 3B are flowcharts of a method for maintaining dynamic management elements by a network device management system according to an embodiment of the present invention.

The network device management system (EMS) 10 according to an embodiment of the present invention analyzes the device configuration information by using information transmitted from the device operation management subsystem (SOMS) 20, and transmits and / or manages each transmission service. Functional elements will be built and maintained. Hereinafter, referring to FIGS. 3A and 3B, a process of maintaining a dynamic management element of the network device management system (EMS) 10 according to an embodiment of the present invention will be described in detail.

First, when the network device management system (EMS) 10 is executed, the network device management system (EMS) 10 transmits an initialization configuration request message to the device operation management subsystem (SOMS) 20 to be controlled. (S301). Then, the network device management system (EMS) 10 receives an arbitrary operation message from the device operation management subsystem (SOMS) 20 (S302).

In this case, when the operation message received in step 302 (S302) is an initialization configuration response or report (S303), since device initialization is started, network device configuration information is analyzed to construct a management component (S304). Subsequently, the transmission service flag is designated with the network apparatus configuration information analysis result (S305).

On the other hand, when the operation message received in step 302 (S302) relates to the shape initialization report or change report of the self or unit unit (S315), the corresponding shape information is analyzed (S316). Subsequently, the corresponding transmission service flag is designated using the result of the corresponding shape information analysis (S305).

Next, the network device management system (EMS) 10 first determines whether the network device is a line signal device (S306). If the determination result in step 306 (S306) is a line signal device, the line device configuration management element is activated or deactivated (S307). In turn, the circuit failure management element is activated or deactivated (S308), and the circuit performance management element is activated or deactivated (S309).

However, if the determination result in step 306 (S306) is not a line signal device, it is determined whether or not it is an Ethernet packet signal device (S310). If the determination result in step 310 (S310) corresponds to the packet signaling device, the packet configuration management element is activated or deactivated (S311). Subsequently, the packet failure management element is activated or deactivated (S312), and the packet performance management element is activated or deactivated (S313).

In this way, when the active or inactive state of the management element is changed, a management element reinitialization process is newly performed (S314). That is, reinitialization of the circuit configuration, failure, performance management element, or packet configuration, failure, performance management element is performed. After that, the process proceeds to step 302 (S302). In addition, if the determination result in step 310 (S40) does not correspond to the packet signaling device, step 314 (S314) is immediately performed.

Referring to FIG. 3B, when the operation message received in the step 302 (S302) is a management element change report (S320), information on the management element change report is analyzed (S321). The information on the management element change report may occur in the device operation management subsystem (SOMS) 20 by the operator changing the management element using the operator connection unit (HMIF) 203. In addition, the management element may be changed in the network device management system (EMS) 10 according to an operator's need. In this case, a user screen unit (GUI) 16 inside the network device management system (EMS) 10 may be used. Direct management element selection can be confirmed (S322).

Subsequently, after the analysis of the information on the management element change report (S321) or the confirmation of the management element selection (S322), the service element for the management element selected by the management element or the operator corresponding to the management element change report is presently present. Check whether it is activated (S323). If the service element for the management element selected by the management element or the operator corresponding to the management element change report corresponds to the currently activated service element, the specified configuration management element is activated or deactivated (S324). Subsequently, the specified failure management element is activated or deactivated (S325), and the specified performance management element is also activated or deactivated.

However, as a result of the determination in step 323 (S323), if the management element requested by the operator is not the currently activated service element, an error is output (S327). After that, the process proceeds to step 302 again (S302).

The management element maintenance function is permanently performed in the network device management system 10. If the termination signal is received from an operating system (OS) (S330), the execution is terminated.

In the integrated delivery system according to the present invention, a method for maintaining a dynamic management element of a network device management system may be embodied as computer readable codes on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also include those implemented in the form of carrier waves such as transmission over the Internet. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.
