    Before enabling the Nastar to collect data from an OSS, you must configure the OSS and NEinformation. After you configure information including the IP address of the OSS and softwareversion, the Nastar obtains the NE list managed by the OSS and analyzes the NEs in the NE listbased on the configured OSS information.2.1 Basic Knowledge of OSS ManagementThis section describes the basic knowledge about the Operations Support System (OSS)management functions. You should grasp the basic knowledge before performing managementoperations.2.2 Creating OSSs and the Managed NEsThis section describes how to create OSSs. You can create an OSS to initialize the protocol ofthe interface between the Nastar and the EMS device so that the Nastar accesses the EMS devicethrough the interface to obtain the required data. In addition, you can set NEs managed by theOSS so that the Nastar collects required data from the selected NEs.2.3 Creating Custom NE GroupsThis section describes how to create custom NE groups. The Nastar client provides the functionsof creating, modifying, deleting, importing, and exporting custom NE groups. You can addcertain NEs to an NE group so that the performance analysis can be performed for all the NEsin an NE group.2.4 Reference for the OSS Management GUIThis section describes the parameters about the interface of OSS management and the parametersfor setting the object attributes of OSS management.

  • 2.1 Basic Knowledge of OSS ManagementThis section describes the basic knowledge about the Operations Support System (OSS)management functions. You should grasp the basic knowledge before performing managementoperations.In the OSS management, objects represent the physical or logical entities on the network. Aphysical or logical entity, namely, an object, can be an OSS or an NE.l Operations Support System

    The operations support system (OSS) defines network management devices that can beconnected with the DAMS. The DAMS collects the required data from a specified FTPserver according to the relevant attributes set in the OSS and saves the data as files in aspecified path on the DAMS server.

    l NENEs are used to identify network devices, such as BTS and BSC.NEs can be classified intophysical NEs and virtual NEs.

    The OSS management subsystem provides the basic functions for managing objects. Thesubsystems such as centralized task management add objects to the GUI through the OSSmanagement subsystem.The OSS management of the DAMS enables you to create and delete OSSs, view and modifyOSS attributes, and manage the information about NEs managed by the OSS.

    2.2 Creating OSSs and the Managed NEsThis section describes how to create OSSs. You can create an OSS to initialize the protocol ofthe interface between the Nastar and the EMS device so that the Nastar accesses the EMS devicethrough the interface to obtain the required data. In addition, you can set NEs managed by theOSS so that the Nastar collects required data from the selected NEs.
