Hi Pix,
we performed some tests and the problem occurs in both codec(EFR and AMR_HR) but in EFR is less than AMR_HR. In TEMS logs file we saw that when the problem with voice quality occurs the SQI is with strongly fluctuating .
The more complains are coming after TFO_AMR_HR activation but it’s normal we use more AMR_HR in this area …
The strange is that there are complains from BSC’s with TFO active but in other BSC’s with the same parameters for TFO, there are no complains ???
My TFO parameters are :
EN_TFO=Enable
EN_TFO_AMR_HR=Enable
EN_MATCH=Enable
EN_OPT=Enable
FORCE TFO HR WHEN LOADED=Not forced
FORCE TFOvsAMR=Disable
KEEP_CODEC_HO=Disable
DL_DTX=Enable
DL_DTX_HR=Enable
Is it possible that the problems are related with TC boards or some parameter in Core Network?
Do you have idea what can be the reason for this problem ?
Best regards,
