Hi Pix, thank you for your answer..
If RADIOLINK_REP_DL_SACCH is not related to my drop increase, what can be the problem changes?
I just changed RADIOLINK_REP_DL_SACCH=30,
REP_DL_FACCH_LEGACY_SUPPORT = 1;
This my current parameter for cell that we tried repeated SACCH/FACCH :
RADIOLINK_RECOVERY_THRES=33;
RADIOLINK_FAILURE_THRES=36;
RADIOLINK_FAILURE_THRES_AMR=36;
RADIOLINK_TIMEOUT=32;
RADIOLINK_REP_DL_SACCH=30(at the moment);
EN_REP_DL_FACCH = 2;
EN_REP_SACCH=1(ENABLE);
REP_DL_FACCH_LEGACY_SUPPORT = 1;
L_RXQUAL_DL_P_AMR_RXACCH=4.0;
L_RXQUAL_UL_P_AMR_RXACCH=4.0;
REP_DL_FACCH_THRES_AMR_FR=12.2;
REP_DL_FACCH_THRES_AMR_HR=7.4;
