Description

T3141 is started after sending a immediate assign and stopped when the MS established the TBF.
From 44.018 version 11.7.0 Release 11:
3.5.2.1.5:
"On the network side, if timer T3141 elapses before a successful contention resolution procedure is completed, the newly
allocated temporary block flow is released as specified in 3GPP TS 44.060 and the packet access is forgotten."

For DL TBF:
- The pcu uses Tassign_agch similiar to T3141.
For UL TBF:
- It's missing. But at least T3169 is started (TFI/USF/TBF re-use timer).

3gpp 44.018 describes T3141.
3gpp 44.060 describes T3169.
