Looks like this is a WIP change.

AFAIR, it depends on the class of a mobile (which defines the multi-slot capability). Modern phones can listen to CCCH/BCCH on TS0 while having an active TBF, older ones don't. Let's clarify that class here (class B and C?).

PS1, Line 707: a Paging Frame
Any spec. references, e.g. coding of this message?

Is there a send template or an encoding function for that?


https://gerrit.osmocom.org/#/c/15623/1/pcu/PCU_Tests_RAW.ttcn@714 
PS1, Line 714: chan_needed
Is there an enumerated type for that?

PS1, Line 715: sapi
2/3 times you're passing 'sapi := PCU_IF_SAPI_PDTCH' directly. Looks like this variable is not really needed.

PS1, Line 743: never arrives
I guess I know why. You're establishing an Uplink TBF, but OsmoPCU also needs to know IMSI of the subscriber this TBF belongs to. Just send a DATA.ind and you will see something like that in the logs of OsmoPCU:

  DRLCMACMEAS INFO MS (IMSI ): Link quality 0dB (0dB) left window [5, 8]...

I don't know how exactly OsmoPCU assigns an IMSI to a TBF, but this should be the way to go.
