Huawei proprietary. No spread without permission.

Important Note:

Nemo post processing tool is not a huawei tool.

But on my project this is special requirement of customer to do drive test with Nemo & Drive

analysis with nemo analyzer.

You can get Nemo analyzer tool at bellow address http://www.anite.com/nemo.

You can get soft & Hard license at bellow address Pay and apply on given web

http://www.anite.com/nemo

Apart from license version you can use Nemo without License ( Crack Versions ).

I don’t know where to get nemo analyzer crack version.

When I used this tool My project team provide me Hard dongle( It look like external USB

drive.

How to get the Nemo Analyzer Tool and license






We have to use Nemo drive testing tool to collect

drive logs.

If you are using Drive test tool nemo than only u can

process logfiles in into nemo analyzer.

Huawei Genex probe Log we can not process in Nemo

analyzer.

How to get the Nemo logfiles



Follow the next slide to do call drop analysis

Step1 Open nemo Analyzer

Step2 Open file menu

Step3 Open measurement

Step4 choose the Log files Which u want to do analyze

In Folder contents

you will get all

logfiles

How to import logfiles in Nemo Analyzer Tool



Analysis Process



1 ) Double click on any event which u want to do analysis. Example:- U want to do analysis for CAD ( call drop), double click on CAD 2) You will get one analysis window where u can check for RSCP , ECIO , PSC for active, monitor and detected set & MAP Window. Check the next slide

No of failure events in selected logfile

Failure

Event

Type

Name of Logs file where

the event occurs.

Event

occurrence

time

Serving

Band

information



RRC signaling

messages and

Event messages

Check here: RSCP &

PSC for active,

monitor & detected

set

If u want to see any

additional parameter .

Select that logs first

and just search here in

search box and drag

where u want to see it..

See in next slide

Check first :- ECIO,

TX power and BLER

of best active set

Check geographic

view o area near to

event

Check:- event

occurs time.

Call Drop Analysis

Check one by one .

First check the RF condition,

Distance form serving cell,

Than check overshooting , check pilot

pollution, L3 massages , etc…



Drag the search

parameter in to RSCP

window .

Example : here we

want another

parameter like RSCP

detected set

Here no PSC and RSCP of

detected set

Importing parameters



Here u will get new parameter .

like detected set RSCP and PSC

Importing parameters



Radio condition before call

drop , RSCP & ECIO both

area good and no

overshooting , no pilot

pollution

Call Drop Analysis



Here you can check the radio condition is

changes, coverage gone poor & quality both are

not constant and due to quality UE increase TX

power to compensate the quality issue.

Some overshooting cells also present due to

poor coverage in that area.

Call Drop Analysis



Here you can check BLER is good

One Detected set PSC we are getting and it is not

sure that Poor quality is because of that detected

set. It might be any obstacle in between call drop

location and serving cell, we need to check the any

alarm. We need to check the Neighbor relation with

all the cells on that are. It might be sue to missing

nbr.

Call drop time recorded in nemo

will be include call drag time also.

Actual call drop happened before

call drop event.

Actual call

drop here

Nemo record

call drop here

Call Drop Analysis



Call Drop Analysis



Actual call

drop here

Nemo record

call drop here

Here UE loss the

connection TX

power & DL power

Up No information.

Call Drop Analysis



When best active set is

423- 221 is defined nbr

for 423.

Call Drop Analysis



Now You can check in previous and

current slide.

When best active set is 423- 221 is

defined nbr for 423.

When best active set is 430-221 is not

defined as shown in detected set .

And due to that missing nbr 430 is not

able to give HO to other cells like PSC-

372.

Here we need to define 221 as Nbr for

430

Click on Arrow to go back in event list to analysis

another failure event.

Check Next slide …

Back to failure event list



Here U will get list of failure events in

nemo logs file.

Above results are shown for one log, if

you have few logs you can join all the logs

and get combine results .

Go and check the steps

View Organize measurements Tool

In Tool you can choose logs which you

want to combine , right click and join and

give new name as u want .

Log File name

Note :

Above explanation was for call drop analysis in nemo Analyzer.

For further analysis you can check the BSS KPI form M2000, PRS & Omstar.
