Bug #4023
openMissing coverage of PCU interface in osmo-bts
80%
Description
let's use this as a separate ticket from #3750 to provide a more verbose list of the tests related to the PCU interface
Checklist
- BTS->PCU: TIME_IND
- BTS->PCU: DATA_IND (PDTCH / PTCCH)
- verification of PCU-originated DATA_REQ arrival on Um/MS side
- existing tests: "FIXME: how to check this wasn't actually sent and didn't crash BTS?"
- verification of INFO_IND data like timers, CS-mask, mcc/mnc/lac/cid/rac/nsei/bvci
- verify that second connect to socket gets discarded while first survives
- PCU->BTS: PCU_IF_MSG_TXT_IND -> OML ALERT
- PCU->BTS: DATA_REQ on PCH
- BTS->PCU: RTS.req, for all lchan on all ts on all TRX
- BTS->PCU: RR SUSPEND -> PCU_IF_MSG_SUSP_REQ
- Ensure that GPRS capability is no longer advertised in SI3 after socket disconnect
- Ensure that PCU can disconnect + re-connect on PCUIF socket

Patch https://gerrit.osmocom.org/#/c/osmo-ttcn3-hacks/+/14183 introdcues the use of virtphy to verify the Um side while performing PCU Socket testing of the BTS. It currently verifies PDTCH + PTCCH only, and only the valid/successful scenarios.

[ ] verification of INFO_IND data like timers, CS-mask, mcc/mnc/lac/cid/rac/nsei/bvci
AFAIR, osmith recently implemented some related test cases.

Right, this test checks the cid and lac and it could be extended to test more: https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/15328
Note that it is currently failing, because OsmoBTS sends empty INFO_ind to PCU socket, if not all SI arrived from BSC via RSL (#4179).
