1 OverviewAbout This Chapter

The Nastar is deployed on the EMS side of an operator's network. The Nastar collects required

analysis data from NEs through the EMS data center, and provides theme analysis for network

optimization. The optimization adjustment results of the analysis can be saved as files and sent

to the Configuration Management Express (CME) of Huawei or a third-party data configuration

tool. These results can be provided as reference for network optimization.

1.1 Position of the Nastar on the Network

The Nastar is deployed on a distributed client/server (C/S) network and is connected to an

element management system (EMS).

1.2 Analysis Data Sources (GSM)

The Nastar mainly uses the following three types of data during the analysis of GSM networks:

GSM configuration data, GSM engineering parameters, and data related to Nastar analysis.

1.3 NetworkOptimization Process

The optimization process of the Nastar consists of collection and check of basic data, network

evaluation, further optimization of each theme, and evaluation of optimization effect. All the

operations on the network must be recorded in details.

Functional Unit Function Description

SAU SAU is short for Service Aware Unit (SAU).

The main functions of the SAU are as follows:

l Collecting raw data from BTSs

l Preprocessing raw data and saving the preprocessed data

l Uploading the preprocessed data

In a GSM, UMTS, or CDMA network, an SAU must be configured

2 Configuring OSSs and NE InformationAbout This Chapter

Before enabling the Nastar to collect data from an OSS, you must configure the OSS and NE

information. After you configure information including the IP address of the OSS and software

version, the Nastar obtains the NE list managed by the OSS and analyzes the NEs in the NE list

based on the configured OSS information.

2.1 Basic Knowledge of OSS Management

This section describes the basic knowledge about the Operations Support System (OSS)

management functions. You should grasp the basic knowledge before performing management

operations.

2.2 Creating OSSs and the Managed NEs

This section describes how to create OSSs. You can create an OSS to initialize the protocol of

the interface between the Nastar and the EMS device so that the Nastar accesses the EMS device

through the interface to obtain the required data. In addition, you can set NEs managed by the

OSS so that the Nastar collects required data from the selected NEs.

2.3 Creating Custom NE Groups

This section describes how to create custom NE groups. The Nastar client provides the functions

of creating, modifying, deleting, importing, and exporting custom NE groups. You can add

certain NEs to an NE group so that the performance analysis can be performed for all the NEs

in an NE group.

2.1 Basic Knowledge of OSS Management

This section describes the basic knowledge about the Operations Support System (OSS)

management functions. You should grasp the basic knowledge before performing management

operations.

In the OSS management, objects represent the physical or logical entities on the network. A

physical 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 be

connected with the Nastar. The Nastar collects the required data from a specified FTP server

according to the relevant attributes set in the OSS and saves the data as files in a specified

path on the Nastar server.

l NE

NEs are used to identify network devices, such as BTS and BSC.NEs can be classified into

physical NEs and virtual NEs.

Physical NEs are actual telecommunication devices of Huawei on the network.

Virtual NEs are the NEs that actually do not exist or are telecommunications devices

of other vendors on the network.

The OSS management subsystem provides the basic functions for managing objects. The

subsystems such as centralized task management add objects to the GUI through the OSS

management subsystem.

The OSS management of the Nastar enables you to create and delete OSSs, view and modify

OSS attributes, and manage the information about NEs managed by the OSS.

2.2 Creating OSSs and the Managed NEs

This section describes how to create OSSs. You can create an OSS to initialize the protocol of

the interface between the Nastar and the EMS device so that the Nastar accesses the EMS device

through the interface to obtain the required data. In addition, you can set NEs managed by the

OSS so that the Nastar collects required data from the selected NEs.
