We’ve just completed our tests with different values of T_NETWORK_RESPONSE_TIME (1.6, 1.2, 1, 0.8 and 0.6 sec) and got rather curious results. Yes, TBF_drop_rate (mainly in DL) really decreased 🙂
Experimentally we found out the most appropriate value (for these 2 BSCs) = 0.8 sec.
If you are interested in this question I can send you some graphics 🙂
P.S. we don’t see any deteriorating of main KPIs and don’t receive subscribers’ complaints, but still – we’re concerned about possible (maybe latent) quality degradation, so we don’t apply new value widely…
