Huawei PCHR

HUAWEI TRACE RECORDING  The most commonly used tracing features is the CHR (Call History Recording) and IOS (Cell Trace). Both log files are in form of binary files, CHR has different type of files PCHR, UCHR, and CHR.  PCHR is Call history log files, not an event based log files like Ericsson GPEH for example. It’s contain all calls in the RNC. Hence the amount of data’s is a lot bigger than GPEH. Notice the speed on the process is a little slow and we are working on the performance to speed up the process.  Available Tools in the market to Analyze Huawei tracing:  Nastar (Commercial Huawei) PCHR Analyzer (Internal Huawei)  Actix One, Aexio,Schema etc (Third Party)  TEMS Visualization

PCHR (PERFORMANCE CALL HISTORY RECORDING)





 There are few types of call log inside the PCHR, In current release TV will support log type 6.  Log files is presented per call (IMSI) basis, imagine this is as the larger scale of Ericsson UETR.  PCHR comes in different version and Model based on Huawei RAN releases. It’s reflected on the .xml file.  Version = V900R013  Model = C00SPC200  We need to make sure we obtain these .xml file from the customer.  The PCHR's log files are generated automatically and stored under the BAM folder as below:  R12 : /bam/common/fam/famlogfmt  R13 : /bam/common/fam/famlogfmt/pchr

DATA SOURCE  TEMS .Cel file with neighbor information (same format)  PCHR log files : download files from BAM folder, if files is not available then we activate the recording. Unlike GPEH once the recording is active it will be infinite until cancelled.  Tracing activation can be done thru MML command  SET PCHRCTRL  RNC  SET CHRSW  NODE  Use HUAWEI LMT tools to enable all the fields.  EXP CFGMML  Export Bulk CM, to be done per RNC.  Phone Model File (same format)
