Ericsson Cell Trace

Hi,
Does anybody know how can we active trace file for each cell or each carrier of 4G sites individually, instead of all in one eNodeB for Ericsson vendor? We encounter with limitation of trace file size, which is 30MB for 4G eNodeB sites while there exist about 21 carrier totally. So, we want to active a specific trace file for each individual carrier or cell in ENM.
Thanks

Hello, you can use cellid parameter:

ue enable -ue -traceref <traceRef> [-timeout <min>] [-setTmsiDynamic]
        - Activates Ue selective RBS Ue trace for specific traceRef
         <traceref> is specified in hexcode (max 6 bytes)
         A maximum of 8 UE's only can be selected for selective tracing[all RUT's inclusive] (or all UE's can be enabled)
         Optional -timeout <min> specified in minutes [1..720]. 0 = No Timeout. Default is 120 minutes.
         Optional -setTmsiDynamic flag indicates if <traceref> should be assigned to TMSI of applicable UE dynamically.
ue enable -cellid <cellId> [-endc] [-mp] -allue [-traceNewUes]
        - Activates all UEs on selected cell.
          if endc is specified only endc capable ue:s will be traced,
          -mp flag cause traces will be collected only on the main processor (excluding BB)
          -traceNewUes flag indicates that only newly registered Ues will be traced
ue enable -cellid <cellId> <maxUeinCell> [-endc] [-mp] [-qci <qci> | -qcis <qci1,qci2,qci3...> ] [-timeout <min>] [-traceNewUes]
        - Activates maxUeinCell [1..8]
          number of cell selective RBS Ue traces in specific cell.
          if qci is specified only ues with bearers with specified qci will be traced,
          if endc is specified only endc capable ue:s will be traced,
          Optional -timeout <min> specified in minutes [1..720]. 0 = No Timeout. Default is 120 minutes.
          A maximum of 8 UE's only can be selected for selective tracing[all RUT's inclusive] (or all UE's can be enabled)
          Optional -mp flag cause traces will be collected only on the main processor (excluding BB)
          Optional -traceNewUes flag indicates that only newly registered Ues will be traced

Thanks a lot. I’ll do it. :pray:

Thanks. This commands is for UE Trace setting. We are looking for Cell trace, and we want to set trace file for each cell ID individually to report an output file separately.

Yes, you are right. I didn’t find any parameters you looking for. ENM(PMIC) splitting large traces automatically, but each cell can be separated at post processing.

Thank you very much

Thx, How decode this?

ENM has tools on scripting VM like

lteCellTraceFileDecoder -h

lteUeTraceFileDecoder -h

or GUI

hi dear ;

could you please more detials about LTE UE trace step by step if you have a time !!

thank you

10

where can find scripting VM or GUI ?

Hi, @LY_Bro, it is a one of virtual machine, part of Ericsson Network Manager.

12

I did a LTE UE trace and got a recorded files but they encoded how i can decode the record or hw can display the LTE Ue trace ?

13

To decode use lteUeTraceFileDecoder in ENM

14

sorry I don’t under stand you please more clarify if you have time

If you have Ericsson Network Manager (OSS) you can run builtin decoder on scripting virtual machine to decode traces.
