Hello,

It is indeed possible that in this one cell, there is one faulty MS. You just have to wait that this customer complains about impossibility to finish a transfer (or hanging transfer).

You can try to increase the detection threshold (how many times the window is stalled…)

N_STAGNATING_WINDOW_DL_LIMIT
if the problem is in DL,

or…
N_STAGNATING_WINDOW_UL_LIMIT
if the problem is in UL.

(there are 2 different indicators : (UL) GPRS_UL_TBF_drop_N_stagnatingWindow and (DL) GPRS_DL_TBF_drop_N_stagnatingWindow )

Regards,
