can you please explain how the changes in these parameters will yield improvement in TDR, also share if any other KPI is going to be affected if changed…???

@Bill:I have changed the value of these parameters in my network to full value 250 each and now my drop rate is around 0.70 to 0.8020th September 2011 at 07:13 #43952pixGuest
these timers are used in TBF Drop Rate detection… it’s like the radiolink timeout for the call drop rate. Increasing it to the max means that the user feels like the network is “frozen” and will probably stop the packet connection by himself.
On top of that, the TBF is not released for a very long time, which should increase the TBF congestion rate.
In the end, I doubt it is a good idea to increase these “Nxxx” counters to a value that’s too high. It’s an artificial fix that only enhances the KPI, but not the end-user qos.
(that’s just my opinion on the topic…)
