traffic statistics; Instant display of traffic statistical task results through line, column, and pie

charts; simultaneous display of double Y axis and multi indices; supports 2D and 3D images;

Exporting queried results in Excel (*.xls) format.

2.3 System Architecture and Networking Diagram

2.3.1 System Architecture

Nastar GSM Edition consists of four main modules and one tool to periodically import traffic statistics.

TransData (import module) – its main function is importing traffic statistic data and BSC configuration data to SQL SERVER database. Its other functions include viewing traffic statistic registration results, displaying current database information, and backing up current task information.

Nastar, (main module) – a client program. Nastar functions include customizing and querying traffic statistic task, and instantly displaying queried traffic statistic results. It supports multi-mode display of variously analyzed node views, navigation windows, legends and line test data;

NaConvert: This tool is installed on a Huawei BSC BAM computer. It retrieves the latest generated traffic statistics from BAM. After conversion, the data is transferred to the traffic statistic server by FTP. then The traffic statistics import program in the server dynamically imports the data to the SQL SERVER database;

Nastar employs the client/server mode. The database applied in the server is the SQL SERVER database. The client end accesses to the server via TCP/IP. See Figure 2-1.


2-3

Figure 2-1 Nastar system architecture

2.3.2 Networking Diagram

Nastar is applicable to two modes, local and client/server networking modes.

I. Local mode: It is consisted of two application modes: offline and online.

Offline mode: The installation of SQL SERVER 2000 is not necessary. Nevertheless, only the functions related to network planning and customization are available. The traffic statistic analysis and related functions are unavailable.

Online mode: The installation of SQL SERVER is required. All the functions concerned with traffic statistics provided by Nastar are available. All the traffic statistics and analysis data are stored on the local computer.

II. Client/Server

A client can be an ordinary PC. The hardware at the server, as is recommended, should preferably be a server, but an ordinary PC is also acceptable. A client and a server can interconnect over TCP/IP in a simple LAN mode.

SQL SERVER is not needed at the client. Instead, it is required at the server. Traffic statistical and configuration data are imported to SQL SERVER database in the server by TransData. The engineering parameters are stored in the client.

III. If dynamic import is necessary, the coordination of Huawei BSC BAM and network connection is required.

Figure 2-2 Networking diagram for dynamic import


2-4

IV. Networking diagram for dynamic import

As shown in IV. , NaConvert is a program installed in BAM. It serves to convert traffic statistics and transmit them to the server via FTP. After that, the statistics are imported to the SQL SERVER database by the import program in the server. An access to the server from the client program can be implemented by a remote dialing or through a dedicated line. In this way, the traffic statistics can be retrieved automatically and in semi-real-time.

3.2 SQL Server Installation

The following procedure is an abbreviated version of the installation set up procedure on the help file attached to Microsoft SQL Server 2000 Standard Edition. For further details, refer to the aforementioned file.

To install SQL Server:

Steps:

1) Insert MS SQL SERVER 2000 Standard Edition installation CD-ROM. If the disk is in auto run mode, the program displays the following interface (Figure 3-1). Otherwise, run the installation file in the CD-ROM.

2) Click SQL Server 2000 Components (encircled in the following figure).

Figure 3-1 Initial installation


3-3

3) Click Install Database Server, and the installation program will prepare to install SQL Server. In the Welcome window, click Next.

Figure 3-2 Select an installation type

4) In the Computer Name dialog box, the Local computer option is set by default, and a local computer name displays in the Edit box. Click Next.

For a remote installation, click the Remote computer option, Type a computer name, or click Browse to select a remote computer.

If a cluster has been detected, the "Virtual server" item is the option by default.

5) In the Installation Selection dialog box, click Create a new installation of SQL Server or install client tools option. Click Next.

Follow the instructions as specified in the user information, the user license agreement and guidance lines, and then:

6) In the Installation Definition dialog box, click Server and Client Tools option, and click Next.

In the Instance Name dialog box, if the Default checkbox is available, install the default instance or naming instance. If the Default checkbox is unavailable, the default instance has already been installed. Just install a naming instance.


3-4

To install the default instance: select the Default checkbox, and click Next.

To install a naming instance: clear the Default checkbox, and type a new naming instance in the instance name edit box.

Click Next.

7) In the Installation type dialog box, you can choose one of three options: Typical, Minimum, and Custom. Select Custom if you want to select components and sub-components, modify the character set, network database, or other settings, and click Next.

8) In Services Accounts dialog box, you can choose to either Use the same account for each service or to Customize the setting for each service to set logon user name and password. Under Service Setting list box select:

Use the local system account - or - Use a domain user account (binding SQL Server service). The former option is recommended (Figure 3-3).

Click Next to open the Authentication Mode dialog box.

Figure 3-3 Services Accounts setting dialog

For information about services accounts, refer to the "Service Account" section of SQL Server 2000.

9) The Authentication Mode dialog box includes two options: Windows Authentication Mode and Mixed Mode.


3-5

In the first option, the server side must authenticate the client side in the Users and Passwords settings in Windows Control Panel, a choice that may unnecessarily prolong the procedure.

The second option is faster: it only requires the client side to type user name and password to access the server (Figure 3-4).

Figure 3-16 Preparation to install MSDE

2) Installing MSDE (Figure 3-17).


3-15

Figure 3-17 Installing MSDE

Note:

There is a configuration file named ‘setup.ini’ in your MSDE installation folder, in which the INSTANCENAME item represents the MSDE instance installed in your computer, with ‘Genex’ as the default value. When Nastar GSM logs on MSDE, the server name should have ‘machine name\instance name’ format instead of an instance name only. If you want to reinstall MSDE, you don’t have to uninstall MSDE, but must assign another instance name (similarly as you add a new instance of SQL Server). However, if you want to use the old instance name, you must uninstall the SQL Server program with this name. Additionally, MSDE doesn’t delete the instance file in the folder of SQL Server, and you should delete it manually, and then install it again.

3.5 About Update

The full installation path folder contains three folders: Nastar GSM, GENEX Shared, and MSDE. In the course of installation, the installing program looks for the GENEX Shared and MSDE folders, and if it doesn’t find them, then it skips installing them.

When you update Nastar GSM, if you have installed GENEX Shared and MSDE, you can download only the Nastar GSM installation folder; if not, you have to download all of them.

Chapter 4 Project Management

Nastar GSM client side program uses the Project management concept to organize data and user operations. The following is an introduction to Nastar GSM project management concept, with a description of how to use the project management functions.

4.1 Summary

4.1.1 Online Mode

Nastar GSM uses client/server architecture. The server side uses SQL Server database system to store traffic statistic data and .DBF configuration data, and provides the client side with access to data. Using TCP/IP protocol, the client side connects to the server side and accesses data to display user's operations such as queries.

Nastar GSM main functions are Traffic Statistic Analysis, Network Optimization, and Traffic Tracer. The data required by the Traffic statistic function is stored on the server; however the data required by the Network Optimization function can be either downloaded from the server or imported from engineering parameter list via Microsoft Excel format (*.xls) using local import function. The data required by the Traffic Tracer data analysis function can be imported directly into local project via local import function. It supports multi-view analysis and message code analysis.

In online mode, the client side program can connect to SQL Server and use functions including Traffic Statistic, Network Optimization, and Traffic Tracer.

In local mode, the client side cannot connect to SQL Server. It can use only local data, and provide Network Optimization function points unrelated to Traffic Statistic function and complete Traffic Tracer function.

4.1.2 Project and Its Management

Nastar GSM client side applies Project concept to organize and manage data. A project defines available operations and operable data; it also stores the operation results.

The project has two connection modes: online mode and local mode. Available operations depend on the connection mode.

The project defines global configurations including connection mode, server address, and local network pending analysis; in addition to start time, end time, and busy time for traffic statistic analysis. The project also includes project information, and to


4-2

support network optimization analysis: configuration information of network pending analysis.

Network analysis results are stored in the project; therefore, after reopening the project, the user can continue the network optimization operation and use the previously stored results.

As to local network units, the SQL Server stores information including traffic statistic data, and configuration data of one or several local networks. An online mode project analyses one corresponding local network. While a local network on server can be mapped to several independent projects.

The client side program offers a series of project management functions such as New Project, Configure Project, Delete Project, etc.

4.2 Operations of Project Management

Figure 5-49 Toolbar

Note:

The imported engineering parameter table must contain “planprop” and the value can be read by system, for example: in a cell record, this line value is “City”, “Suburb”, or “Town”.

In setting “attribute setting”, make sure to set the smallest down-line level, BTS coverage distance and transmit power. These three attributes much affect plan result, so please carefully. The best optimization policies are recommended as follows:

Antenna setting:

It is better to import more and more antennas; You had better accord to imported cell plan attribute and pro rata to allocate

antenna usage range pro rata, the usage range of antenna is default to “City”. If some cell fails to match with suitable antenna and that fails to prompt plan, it is

necessary to view its plan attribute and set much more.

Global attributes setting:

The grid size affect on plan speed, the size is bigger, plan speed is slower, and generally, the default value is 50.

You can accord to locale to set the transmit power of city, suburb and town, and the BTS coverage range and the smallest down-line receiving level, in which, the smallest down-line receiving level is the most pivotal attribute in automatic plan, its value directly decide plan result.

The smallest down-line receiving level reference Table 5-3:

Chapter 6 Traffic Statistics Preparation

6.1 Overview

Traffic statistics computes and analyses traffic statistic data for user. It requires data preparation works including Two steps:

TransData

It statically imports the data files that StatTrans extracts into Nastar database server. It also supports dynamic data import into OMC traffic statistic platform.

GENEX Nastar GSM

To guarantee accurate and quick traffic statistic task execution, we need to do some pre-setting works on Nastar client end.

6.2 StatTrans

This tool is convenient to divide traffic statistics files and import them. OMC traffic statistics files are always large and not classified according to time so that it is difficult to return them on the spot. Now this problem is settled by the tool though the divided files can not be checked with OMC traffic statistics console, but statically imported by TransData and checked with Nastar GSM.

Steps:

1) Select [Start / Programs / GENEX Nastar / Tools / StatTrans], as the following figure:


6-2

Figure 6-1 StatTrans interface

2) In Source Directory, Select the traffic statistics public information file, pubinfo.tsk. If you select it through Browse, the task information is shown automatically in the window; however, if you type the address directly, you should click List Statistic and select the desired task and time.

3) Click Convert to export data into the fixed directory (usually C:\ Program Files\Huawei GENEX\Nastar GSM\Tools\Transfer ). The file name is the same as the original one. You can use these files to import data statically.

6.3 TransData

6.3.1 Start SQL Server

At first, Install SQL Server 2000 on server (Can be PC or laptop) and run Service Manager. After that, start SQL Server service (It is recommended to set SQL server to auto run after starting OS). Once the service starts successfully, on Windows task bar, there is a green arrowhead (Figure 6-2).


6-3

Figure 6-2 SQL Server service manager

Under remote import mode (TransData accesses SQL Server through LAN to implement data import). We must create a directory \NastarTmp on SQL Server machine for share. Under this directory, place a file named exedir.loc, and write a clear path of the \NastarTmp directory in it. A sharing password is also required. When running TransData for the first time, input the network directory manually. Enable program to remember the password. When these operations are done, later static import will appear the same like local import. The program will automatically copy the processed traffic statistic data to the \NastarTmp directory, and import the data to SQL Server.

The content in exedir.loc file can be simply like the following:

E: means the path of the \NastarTmp directory is E:\NastarTmp.

Note:

The traffic statistics takes a large space of the hard disk. To store the BSC traffic statistics, ensure that the free space of the hard disk is larger than 10GB.

6.3.2 Data Preparation

BSC traffic statistic files and BSC data configuration files are required for traffic statistic data import.

6.3.3 Use TransData

Chapter 7 Statistic Data Analysis

7.1 Overview

Tasks in the task tree are the essential part of Nastar. Each task reflects a requirement which is hard to implement by user on the traffic statistics console, for example, customized reverse index contribution rate query, worst cells of the last week query (or one month), long-term BSC parameter trend query, and extreme busy and idle cells in the last week query.

We have customized dozens of tasks to satisfy customers’ requirement. After double-clicking a task item, input time span and parameter needed to query. Meanwhile, some item can be displayed correspondingly. For example, traffic capacity or traffic fail rate can be shown in the geographical view, and line, pie and histogram charts can be customized. These tasks will satisfy most requirements of current network optimization works that engineers care about. What is more, we open the task generation window. Experienced network optimization engineers can customize their own tasks (including correlative display of results). They can also export tasks in .DAT format files, and send them to other engineers, so that these tasks can be shared by other engineers through importing .DAT files.

According to different equipment features of different vendors, we designed public tasks and special tasks to support normal and advanced network maintenance, analysis and optimization.

Besides, the statistic task provides analysis of network resources utilization ratio. Through flexible tasks and powerful databases, a large number of data can be analyzed, which provides analysis and assess of current network resources. It also provides data support for future network construction and management.

7.2 Result Analysis

We can implement task by double-clicking task item. The result will be displayed in the table window. Result usually consists of three parts. The first part includes public information like time, BSC, regions, area attributes and cell names. The second part contains key parameter that user needs, such as values of query, statistic or calculation. The last part, usually listed in the last line, is the cell index. As an internal index of cells of our system, It is not useful to users, but it plays an import role in our system. Functions like site view auto relative display and quick traffic statistic query cannot function without cell index.

The following operations are available after traffic statistic query:

Chapter 9 Network Daily Monitoring Report

9.1 Overview

This chapter introduces how to generate reports. It includes four parts:

Daily report – includes the whole network items investigation and VIC. The whole network investigation analyzes KPI and resource usage rate to research the network’s daily condition.

Weekly report – analyzes KPI and resource usage rate to research the network’s weekly condition.

Monthly report – analyzes KPI and resource usage rate to research the network’s monthly condition.

Semimonthly report – collects and analyzes the current network performance data and system data, and then scores the whole network condition and main items. With the semimonthly report, the engineer can consolidate some key measurable items, examine them, and control the on-the-spot situation. This function can reduce item inaccuracy resulted from human factors.

Carrier report – tests the level performance on the carrier’s uplink/downlink according to the conditions specified by the user, filters the results by TA traffic distribution performance test or uplink/downlink balance performance test, then is generated in the EXCEL format.

Quality Report – According to statistic evaluation on the BSC traffic statistic key items, the system generates the quality report in order that the headquarter can monitor the network quality of every region.

Chapter 2 Monitoring Report –According to statistic evaluation on the BSC traffic

statistic key items, the system can ayalyze access, drop, turnover, performance, and othe KPI items to monitor network running quality.

4.5 How to Identify of Cell Symbol Meaning

Question:

How to identify meanings of cell symbols “B”, “T”, and “B-T” and “T-T’ during the cell co-channel and adjacent channel check?

Answer:

When both BCCH and TCH are selected in the dialog box of the cell co-channel and adjacent channel check, the system identifies meanings of cell symbols “B”, “T”, “B-T” and “T-T” that correspond to all co-channel and adjacent channel cell IDs of the whole network. The meanings of these symbols are as follows:

“B-T”: It means that the BCCH value is the upper (lower) adjacent channel of the current frequency band. Meanwhile, some value of the TCH is the lower (upper) adjacent channel of the current frequency band.

“T-T”: In the TCH values, there are both upper and lower adjacent channels of the current frequency band. But the BCCH value is not equal to or adjacent to the current frequency band.

“B”: It means the BCCH value of the cell is the upper (lower) adjacent channel of the current frequency band. The TCH value is not equal to or adjacent to the current frequency band.

“T”: It means that among the TCH values of the cell, only one is the upper (lower) adjacent channel of the current frequency band. The BCCH value is not equal to or adjacent to the current frequency band.

4.6 Lack of Corresponding Neighborhood of Selected Cells

Question:

Why there is no corresponding neighborhood of the selected cells on the map after neighborhood configuration is imported?

Answer:

This problem may be caused by two reasons.

Reason 1: The current working layer is automatic neighborhood planning. Click

to switch to the neighborhood configuration layer.

Reason 2: When the neighborhood is imported, the system enables the unique matching based on LAC+CI. Make sure the imported engineering parameters of the adjacent cell include LAC+CI data and the data corresponds to the neighborhood uniquely.
