PS1, Line 235: /* 3GPP TS 44.018, table 9.1.8.1, note 2b: Request Reference shall be set to 127
: * when Immediate Assignment is triggered by EGPRS Packet Channel Request. Here
: * we assume that 11 bit RA always contains EGPRS Packet Channel Request. */
: if (is_11bit != 0) { ra := 127; }
This should have not been removed. That's why the related test cases fail.

PS1, Line 48: GsmRrMessage
Do we really need to store the RR Immediate Assignment in a TBF record? As far as I understand, we parse it and store all parsed parameters here. What if a TBF was assigned on PACCH? There would be no RR Immediate Assignment content to store here.

PS1, Line 49: PacketDlAssign ass,
: PacketDlAssignment rlcmac_ass,
Please add a couple of comments here, what is the difference between both? If I understand correctly, 'ass' contains parameters from CCCH assignment message and 'rlcmac_ass' contains parameters from PACCH assignment message.
It also makes sense to use a union here and properly name its members: 'ccch_ass', 'pacch_ass'.

Same comments apply here.

: DlTbf dl_tbf optional
Please add a comment that there can be more than one UL/DL TBF.
