| Integration Tests for OsmoBSC which we can perform from TTCN-3 |
| |
| = exhaustion of resources |
| |
| * send many CHAN RQD (any) and count if all channels get actually allocated |
| ** verify BTS_CTR_CHREQ_TOTAL reflects number sent on RSL |
| ** verify how quickly they get released again |
| ** verify that CHAN RQD with same RA + FN get only on allocation |
| * verify that we get IMM_ASS_REJ once channels are exhausted |
| ** verify BTS_CTR_CHREQ_NO_CHANNEL increments accordigly |
| * verify for particular channel type / cause values |
| * verify that IMM.ASS.REJ has increasing back-off |
| * verify how BSC reacts to AGCH overload (DELETE IND) |
| |
| |
| = paging |
| |
| * page by TMSI vs. page by IMSI |
| * verify if CCCH_LOAD_IND(PCH) slot count is observed |
| * verify paging expiration |
| * paging with different identity (lac/cgi/...) on A interface -> expect on right BSC(s) |
| |
| = hand-over |
| |
| * intra-BSC HO |
| * handover detect when not expected |
| |
| = erroneous channel release |
| |
| * no response to CHAN ACT |
| * CONN FAIL IND from BTS |
| ** verify counter increment of BTS_CTR_CHAN_RF_FAIL |
| * no (or late?) response to RF CHAN REL |
| * no (or late?) response to RLL RELEASE REQ |
| * RLL messages on not-activated channels |
| |
| = misc |
| |
| * SMS-CB |
| * behavior in case of CHAN ACT NACK |
| * EST REQ for SAPI3 originating from core |
| * behavior of BSC in various error cases (ERR IND) |
| ** BTS_CTR_CHAN_RLL_ERR increment on T200_EXPIRED |
| * MODE MODIFY with ACK / NACK / no response |
| |
| = IPA voice related |
| |
| * expect IPA CRCX, send UDP flows, expect them on AoIP |
| * expect RTCP |
| * missing RTP flow? |
| * missing RTCP? |
| * missing / drop-outs in RTP flow[s] |
| * no response to IPA CRCX / MDCX / DLCX |
| |
| = counters |
| |
| * test each and every counter in BSC, validate via CTRL interface |
| ** RSL/OML failure: drop link, expect BTS_CTR_BTS_xxx_FAIL +1 |
| ** paging |
| *** send PAGING from MSC side |
| *** expect BSC_CTR_PAGING_ATTEMPTED increase by one |
| *** expect BSC_CTR_PAGING_EXPIRED on T3113 expiration |
| ** BTS_CTR_CODEC_* on CHAN_ACT_ACK |
| * new counter ideas |
| ** number of SCCP CR timeouts |
| ** number of incoming RESET from MSC |
| |
| = VTY based/corresponding tests |
| |
| * changes in BCCH FILLING |
| * changes in SACCH FILLING |
