i could say that CHR logs are input for PCHR that is actually R&D software showing many things like different messages before event, u could do some stats,extraction of particular info and etc. Similar to DOT info in Nastar but more user-friendly and showing in my opinion more info. Generally speaking very very useful, unfortunately not available for the latest RAN12.

OK Thanks. Any idea why it was not developed for R12 when it was out for sometime now?

HI ,
still not clear. I have a huawei tool which gives impression as if CHR and PCHR are some distinct entities and PCHR is not just name of tool PCHR analyser. If anyone can shed some further light on it ??

Do you have any description and file formats for CHR logs? This can be valuable information

Nope, i am also looking for. This is bin format and can be read only by specific software.

Do you know if it supports R12?
We don't see the files in one of RNCs and in another RNC the files are missing all the Measurement reports, do we need to activate something in the RNC? M2000?
on the other hand we see HMR files, can they be instead of the CHRs?
Thanks

Finally got the answer from a HW 3G expert:

PCHR records all the “calls” including normal and abnormal.
CHR only records the abnormal calls which is more detailed than PCHR.

I am looking for the file formats for CHR logs, did anyone found some info now?
I just found that CHR logs including User call log, Cell Log and Internal RNC log, but I need some detail info like CHR logs's field.
Can anybody help me? Thanks a lot!

Hi guys,

I can see that there is a confusion about PCHR, this comes from the tool naming. Briefly

CHR: (Call History Record) Detailed info for the abnormal call.
PCHR: (Performance CHR) Limited info for all calls.

Both are the files logged in some specific folders in RNC, you can transfer and use them for troubleshooting. Both files are BIN, so you need to develop your own tool or use the tools in the market.

PCHR Analyzer: This is the tool from Huawei to analyze the PCHR data. The confusion is: PCHR can refer both the files and the tool, but they are not the same. It is like excel sheets v.s. MS Excel tool. YOu can have an excell sheet and open it with Open Office, as you have Aexio for PCHR.

For PCHR, the content of the files are not clear even you decode the BIN, then you need correct configuration xml file. (Thanks to great design from Huawei, each and every sw release can change the whole mapping ;) ) So, if you have PCHR Analyzer but cant decode the PCHR files, this is most likely you are missing correct configuration xml. Find it and it should work.

I hope this helps.

Enjoy...

Good overview for CHR logs.

Now the question - it seems that CHR logs have only records with 01 code which has no description in Config/RNC xml files, while PCHR (UCHR) files have records with 06 and 07 codes that are described in xml files.

Can you elaborate, please, on where and how to find any information for logs with 01 records?

Many thanks in advance....also recent RNC xml files for V900R014 are welcome!!!!!

danikd,

Frankly speaking, I am not working with Huawei files, nor with CHR/PCHR lately, so I am not sure if I can find R14, I will check around.

For the question, I did not quite get it; can you give a bit more detail? What do you mean "01 code", "06 code".

PS: I am not an full time optimization guy, rather doing product and Core. So forgive if my question is dumb.

Once I'm trying to parse PCHR files, according to their structure, each record (call) is separated by 0xAB 0xAB bytes, then after it there is a code 0x06 or 0x07, those codes are for PCHR files 06 is for User Call and 07 is for Cell performance.

Few days ago I got some CHR files for R014 release, in their names was CHR string not like in R012 or R013 UCHR and after 0xAB 0xAB byte only 0x01 code appears. The question that I have - was it a wrong CHR file, which does not contain actual CHR (user calls) data? or R014 has a totally different structure comparing it to R012 or R013 releases?

Please, advise me...

Best regards

++ as you said:
06 is User log
07 is cell performance
and 01 : SPU Single User Log, to be honest I don't what is that? but may be you can upload one PCHR file here from R14 and we will attack it...:-)

============

Any insight about GCHR (GSM Trace), are they having the same .xml format as well?
is there GCHR analyser type of tool?

May be you have a chance to get XML for R014 from PCHR Analyzer????? from someone from Huawei?????

THis XML will save a lot of efforts to get information out from this PCHR.

Also this request to all Huawei experts on this forum

Personally, I promise to share with you the way of using this xml to get info out from PCHR if you need it.

Best regards
