PS1, Line 49: mi->tmsi
gprs_rlcmac_paging_request() is called from
gprs_bssgp_pcu. […]
I have now analyzed this further. The PCUIF really behaves a bit
confusing here. It is true that osmo-bts confirms IMMEDIATE ASSIGNMENT and PAGING COMMANDs
but osmo-pcu will silently drop the confirmations for PAGING COMMAND messages. I have
already fixed this in osmo-bts and we also do not have to worry about the TMSI, we can
just pass GSM_RESERVED_TMSI and everything will be fine.

PS2, Line 33: The caller must use a TMSI/TLLI
Is there anything in the specs. […]
I just
deducted that from the code, we always set mi.type to GSM_MT_TYPE_TMSI. I just wanted to
make sure that we won't overlook anything if we should change this. But since we do
not need the TMSI/TLLI for the confirmation anymore (see below) this line is no longer
needed.
