In the formula we have the accessibility seguintres plots: SDCCH Blocking, Fall and Fail SDCCH channel traffic. I wonder what the relationship between them for this indicator.

What is explain more on RLTIMEOUT and INIT MCS (DL/UL) from 6/5 to 2/1.

Hi Pix,
could you please, give me more information about drops due to N3101,N3103 and Npolling, because I have problems with high level of TBF Drops in UL. The N3101,N3103 and Npolling drop causes are so high...
Is it possible to adjust some parameter related to N3101 and N3103?
The problems with TBF_Drop_UL comes after Extended_TBF_UL activation.
Thank you in advance and wish you Happy Easter holiday :))

the equivalent for "TBF drop" is called N3101 and N3103.

any chance of improving UL TBF Est. Success Rate?

all this data for 2.5G is meaningless

Hi Jacky,
INIT MCS parameters are recommended fir TBF drop improvement. Just to share with you, I changed the INIT MCS (DL/UL) from 6/5 to 2/1 & I got good improvement in the Attach Success rate!!! But there was no impact on TBF drop. Perhaps u may try & share the results.
