1. The number of UEs has exceeded 100

thousand in 2012 and will reach one million in

2013. Therefore, a highly efficient tool must be

developed to support large O&M information.

2. During several fault rectification tests, the

average fault rectification time is over 1 hour,

which cannot meet product requirements.

1. There are many types of tools, such as theOMSTAR, InsightSharp, NIC, AlmTool, PFM,

and UnpackTool.2. Analysis documents vary with product

versions, which are difficult to adapt to.

FMA

1. Data amount is large on the live network

and indicators such as alarms cannot be

fully monitored.

2. Manual network maintenance is difficult

to perform.

1. Locating methods are limited for internal

faults and experience cannot be

accumulated.

2. Import or export of many types of logs are

time- and labor-consumed.

3. A large number of logs are collected

manually, which reduces efficiency.

Multiple tools

Low maintenance andlocating efficiency

FMA Function - Operation Log Analysis

Operation log analysis

The FMA supports basic log operations such as sorting, searching, filtering, number-based jumping, saving, and

double-clicking a log to view detailed information.

The FMA also supports the display of risky commands. Red characters indicate failure operations and red

highlighted characters indicate risky commands. The FMA provides the function of hiding the LST or DSP

command to improve analysis efficiency.

FMA Function - Expert System

Introduction to the expert system

Daily network troubleshooting experience accumulates abundant rules for various data source processing. The FMA

adopts these rules for fast fault locating.

The expert system uses CHR logs as the data source. After the CHR logs are imported, Expertis displayed.

Currently, the FMA supports 16 general rules covering the following three aspects: service drop, handover, and

access.


22/57

This function is to compare any two alarm files before and after an

upgrade or reconstruction.

Alarms are exported from the M2000 in .xls or .csv format.

If alarms are added, cleared, or no alarms are generated, difference of

the two alarm files can be automatically compared.

This function uses the alarm ID and alarm informationas key words.

Page 49

In the right pane, if Differentis displayed under Compare Result, alarms in the two files change.

These changed alarms are marked in yellow.

In an upgrade comparison scenario, if an alarm exists in Alarm Data1but does not exist in Alarm

Data2, the alarm has been cleared. If an alarm exists in Alarm Data2but does not exist in AlarmData1, the alarm is newly reported.

Quick Query of Parameters in MML Command

Output

Page 51

You can quickly check parameters in MML command output in batches.

You can use MML command outputs to quickly query eNodeB and cells where certain functions are enabled, greatly improving efficiency.

Start the FMA and choose Tools> MML inquiry result visualizationfrom the main menu.

The following uses an example to describe efficiency improvement effect for using FMA. The task is to query all the cells in

the record where the value of Cell active stateis Deactivatedin the MML command output file Test Data.txt. Without

using the FMA, you must query records one by one.

If the record query of one site requires 10 seconds, it takes at least 1 hour to find cell IDs one by one for 500 sites.

Alternatively, you can use the FMA tool to save packets as an .xml file, and use the filtering function to quickly find cell IDs.

This method usually takes less than 30 seconds to find cell IDs, greatly improving efficiency.

Uu Interface Parameter Extraction Tool

The Probe can only be used to collect signaling heads but not parameters in signaling. The Uu interface parameter extraction tool can be

used to collect parameters in Uu interface signaling and perform parameter mapping.

On the menu bar, choose Tools> Uu Parameter Collectionto enable the Uu interface parameter extraction function.

Note: The file to be analyzed is a .txt file stored using the Probe. The .txt file is named in the format of

Power Calculation

Page 53

Power calculation varies with eRAN versions, which makes the calculation complicated. The FMA integrates a power calculation tool that

enables power calculation in black box mode, improving work efficiency of field and maintenance engineers.

Choose Tools> Power calculate toolfrom the main menu to start the power calculation function.

A dialog box is displayed, as shown in the following figure. Set the six parameters in the red frame and click Run.
