LTE trace in U2000

[esoestemp]

Hi,
Could you please help with some suggestions how to set up "User performance monitoring" trace in U2000.
For example "DL RSRP/RSRQ monitoring".

The thing is I am lost at the point of obtaining MMEc and mTMSI or Random Value needed as input for the trace.
Thanks!

Since IMSI is not visible ....they demand the MMEC & M-TMSI for eNB level tracing.

[oswe]

you need access to MME. we have access but we dont know the command ;-(((((

Dear All,
Anyone have a guide how to perform LTE Trace
How to get with commands MMEc
what is TRACE ID that appear in Trace window and how to configure it
Thanks

[oswe]

what we did here.
with a certain command you get from MME the GUTI number for your MSISDN (telefone number)
then you have to obtain P-TMSI from this GUTI (check definition of guti for example on blog 3g4g from uk)
then with this number you open "signalling management" on M2000 and perform the trace .

thanks @oswe but do you know what is the TRACEID that appear on U2000 LTE Trace window
also please support with MME commands

Thanks

[P.T.E.]

You can get it from "Attach accept message" or ALLUEBASICINFO on U2000.

Hello,
TRACEID in u2000 LTE Trace window is used if you want to do specific tracing. For example to trace throughput value for related TRACEID and the value is unique

[oswe]

no need for traceID...
go to user performance -> DL RSRP/RSRQ performance then with your MMEc and TMSI you can see your cell and neighbor cells levels.


MME commands



DSP MSISDN
DSP MMCTX






sample


GUTI
m TMSI
MMEc

m TMSI = hex2dec(guti,8)

Hi oswe,

Yeap, that methode also work.
Trace ID explanation is for @gunpowder

[DANORM]

For me when i am tracing some users, sometimes it works sometimes not. Anybody has like that issue?

[sak2e]

Hi,

Please make sure the user is active,some times they turn off their smartphone or something like that. im lucky since now tracing methode is success.

[DANORM]

user is active, because i can trace it via End-to-End user trace, but in DL RSRP/RSRQ monitoring" shows no results.

[sak2e]

DL RSRP/RSRQ monitoring exist in user monitoring right? if yes you need Trace ID for spesific trace.

Trace ID need for End-to-End user tracing not for RSRP/RSRQ, anyway it is generated radnomly.

Hi,

I mean like this if you want to make DL RSRP/RSRQ monitoring:
1. Create LTE end to End, Input = IMSI, Output = Trace ID
2. Select DL RSRP/RSRP monitoring, Input = Serving EnodeB and Trace ID

I tried so many times and it successfully,
Its generally failed if im using tMSI, but i dont have problem if using Trace ID

So you mean like this:

-End-to-End user trace > input IMSI.
- copy generated User trace ID
- run end-to-end trace
-DL RSRP/RSRQ Monitoring > select eNB
- in UEID type > select Trace reference No.
- paste Trace ID
- run RSRP monitoring

for DL RSRP/RSRQ Monitoring, I used > UEID type - STMSI
- MMEc: 1
- mTMSI> from GUTI

and its failed sometimes as you said.

[sak2e]

Yeah,,correct.
you can use trace id as reference instead of mTMSI and it never failed :)

I tried it and its working, thank you ^_^

[sak2e]

Yeah,,

Anytime :) :) :)

[omarGSMUMTS]

you need to get mtmsi and enodeb ID from CN team

Thanks!
That works for me.

[sak2e]

Yeahh,,

Thats methode is very useful for VIP handling and realtime monitoring :)
