Reply To: UL TBF ASR


ok, let’s recap : your UL TBF Establishment Success Rate = 30% in some cells, and the cause of failure is “MS no response”.

Are you sure it is not due to some kind of congestion ? BSC congestion for example ?

30% is was too low to be fixed with parameters fine tuning. You should focus on BTS configuration and hardware congestion or hw fault.

Your UL gprs PC settings were very “safe” 😉

Have you tried rebooting the cell ?

Can you see a pattern ? Maybe all failures are occuring on one specific BSC board ?
