Description

Agent system for managing network interworking device

The present invention relates to an agent system for managing an inter-working function (IWF) for supporting a mobile communication network and a data network, and in particular, provides a GDMO (Guidelines for It relates to an agent system for managing a network interworking device suitable for providing the Definition of Managed Objects model and TMN management function.

As the technology of the communication field has been greatly developed, IWF that can be used by interworking with the existing wired communication network and the newly growing wireless communication network or the Internet, has been required. Accordingly, mobile communication network devices that connect with CDMA digital cellular phones or PCS exchangers and link with wired networks to transmit data such as faxes and texts using mobile communication terminals are being developed.

In order to manage such network interworking devices in the entire communication network, it does not use any standardized interface and modeling, but uses a management method using an interface method and modeling each developed by a communication provider. Currently, the International Organization for Standardization is conducting a number of activities centering on ITU-T to develop network management standards such as TMN. In Korea, various telecommunication service providers are demanding TMN functions.

To meet the needs of these service providers, GDMO model and Q3 interface (CMIP) must be provided at the network node.

However, if the existing equipment does not support the Q3 interface, an Q3-adapter must be added to the existing equipment. ITU-T Rec. M.3010 describes the functionality of the Q-3 Adapter (QAF) and the interface reference point for non-TMN NEs. As the reference point between the Q3-adapter and the management element (non-TMN NE), the M-interface is mainly used, and since the M-interface is outside the TMN area due to its own characteristics, there is no standardization.

Therefore, in the past, most of the equipments used to manage the corresponding devices using IPC or SNMP. Although GDMO models and Q3 interfaces are sometimes provided for ATM switches or recently manufactured network management devices, no examples provide GDM0 models and Q3 interfaces for data network interworking devices (IWFs). That is, in the related art, rather than using any standardized interface and modeling to manage the data network interworking device, each company managed by using its own interface method and modeling. Therefore, the modeling concept of the network element has not been applied because the status of the network element is notified using the IPC or SNMP interface and the control command is processed.

As a result, such a prior art may use a network interworking device without using a standardized interface, which may cause a problem when interworking with other network management systems, and does not systematically model the network management device. There was a limit in providing network management.

The present invention was created in view of the above problems, and an object thereof is to provide an agent system for managing a network interworking device capable of providing a GDM0 model and a Q3 interface for a data network interworking device.

Here, a fifth module for modeling overall performance data of the network interworking device, a sixth module for modeling interface ports and channels provided by the network interworking device, and a seventh modeling for performance information in each channel and port The feature is that it further includes a module.

According to the present invention, it is possible to interoperate with the network management system that requires the TMN function, TMN function and Q3 interface, there is an advantage that can be more systematic management by modeling the data network interworking device to GDMO.

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

1 is a diagram showing a relationship between a management system, a Q3 adapter, and a network element according to the present invention. Referring to FIG. 1, when the Q3 adapter 30 is provided in the TMN area 10, the Q3 adapter 30 is positioned between the network element 40 to be managed and the management system 20 to be managed. Here, the M interface follows a "network element interface method (application number: 98-62376)" filed by the applicant of the present invention in a Real Resource Interface (RRI) interface method, and uses the CMIP interface as the Q3 interface.

Agent system for managing the network interlocking apparatus according to an embodiment of the present invention is the network element interface module 33 for performing an interface with the network element 40 and collect network element management information, as shown in Figure 2, The management information conversion module 32 converts the collected network element management information into TMN management information, and inversely converts control information provided by the management operation of the management system 20 into control information, and manages the inputted management information according to the GDMO definition. It consists of a Q3 interface module 31 which manages the information base MIB and performs management operations defined in the management object representing the network element 40 in accordance with the request of the management system 20.

Here, the network element interface module 33 collects management information from the data network interworking device through the RRI interface, and the management information conversion module 32 converts the data form transmitted through the RRI interface according to the GDMO form, and Q3. The interface module 31 is a module for interworking with the management system 20 through the Q3 interface and uses a CMOP protocol provided by the network management platform.

The agent system for managing the network interlocking device according to the present invention enables the systematic management by modeling the data network interworking device and the hardware configuration, fault state modeling, performance information modeling, and test function modeling.

3 is a diagram illustrating a GDMO model of a network interworking device according to the present invention. Referring to FIG. 3, the fourth module 50 expresses hardware shape information by applying the MO in the existing recommendation as it is.

On the other hand, the remaining modules 60 to 80 except for the fourth module 50 are MOs newly defined in the embodiment of the present invention in accordance with the function of the data network interworking device. That is, the fifth module 60 models the overall performance data of the data network interworking device, and the sixth module 70 models the interface ports and channels provided by the data network interworking device. In the sixth module 70, a port (FrsTrunkTp) 71 providing a frame relay interface, a port (X25 TrunkTp) 73 providing an X.25 interface, a port (PriTrunkTp) 72 providing a PRI interface, Modem ports 74, each providing a modem interface, were modeled, and channels 75-77 configured within each port were also modeled. In addition, the seventh module 80 showed that performance information was modeled in each channel and port.

Thus, faults occurring in ports and channels as well as the shape of each hardware can be handled. In addition, it can be handled because it provides the function to propagate the failure to the corresponding port and channel level when the board fails, and to propagate the failure to the board and the entire system level when the port or channel fails.

The performance information is largely subdivided with the system performance information like the seventh module 80 of FIG. 3 and modeled as performance information for each port and channel. The test function is defined as "ACTION" in the GDMO corresponding to the board and port for which the test is required.

As described above, the agent system for managing a network interworking device according to the present invention may be interworked with a network management system requiring a TMN function and a TMN function and a Q3 interface. There is an advantage that can be systematically managed.
