2019-02-13Fix compilation on eclipse-titan 6.5.1daniel/titan-6_5-fixDaniel Willmann1-1/+1
Newer eclipse-titan makefilegen already sets CPPFLAGS like this: CPPFLAGS = -D$(PLATFORM) -I$(TTCN3_DIR)/include$(TTCN3_SUBDIR) where TTCN3_SUBDIR expands to '/titan' and TTCN3_DIR to '/usr' If we add /titan after include we end up with -I/usr/include/titan/titan/ which will cause the compile to fail due to a missing TTCN3.hh include.

2019-02-11MSC_Tests: run TC_gsup_mt_multi_part_sms latePhilipp Maier1-1/+1
The testcase TC_gsup_mt_multi_part_sms is known to fail osmo-msc in a way that meaninful sms delivery is not possible anymore. This is due to a bug in osmo-msc, but in the testsuit it makes running certain normally working testcases impossible. Lets move at at the end of the testsuite so that it rus late and other tests won't get blocked. Change-Id: I581cd80895ea992a15389c6f73816769864e6d4c Related: OS#3614

2019-02-05bsc: Test CSFB "Fast Return" in new TC_chan_rel_hard_clear_csfbHarald Welte3-2/+56
When a MSC releases a connection using the BSSMAP CLEAR CMD, it can specify that this call was part of CSFB. The BSC is then supposed to add a special IE to the RR RELEASE message which will help the phone to switch back to LTE as soon as possible. This commit adds a new test case testing for exactly that behavior. The test does *not* verify if the EARFCN information contained is actually correct, only that the IE is present in the RR RELEASE.

2019-02-05bsc: replace octet string with decmatch when matching RR RELEASEHarald Welte3-4/+34
The 'decmatch' keyword allows us to match the decoded version of some octetstring, which is very useful in the situations where we have the L3 message only as octetstring but want to check if it matches some L3 template. Change-Id: I0a91e067f7e8062bf991fef8b0d4d8da740bfafc
2019-02-05BSC_Tests: Don't make invalid assumptions about RR RELEASEHarald Welte2-6/+4
The RR RELEASE message does not always have to be '060D00'O, which constrains it to: * not having any optional IEs * not having a cause value != 00 Let's relax the matching to accept any RR RELEASE message, whatever the cause may be, and whether or not there are any optional IEs at the end. At the same time, also remove some copy+pasting but rather have one template that gets used everywhere. Change-Id: I4b9d078c9b66f040fe673b5d957cf8e2c6d5892c
2019-02-01MSC_Tests.ttcn: introduce TC_gsup_mo_mt_sms_rp_mrVadim Yanitskiy2-0/+106
The idea of this test case is to verify SM-RP-MR assignment for a few concurrent MO/MT SMS being sent over GSUP. Basically, the algorythm is the following: 1.0 establish a RAN connection, 1.1 send CM Service Request for MO SMMA indication, 1.2 submit MO SMMA indication on DTAP, 1.3 expect MO-ForwardSM-Req on GSUP, 2.0 send MT SMS using MT-ForwardSM-Req on GSUP, 2.1 expect CP-DATA/RP-DATA for MT SMS on DTAP, 3.0 compare both SM-RP-MR values (for MT, assigned by the MSC), 3.1 send MO-ForwardSM-Res for MO SMMA on GSUP, 3.1.1 expect CP-DATA/RP-ACK for MO SMMA on DTAP, 3.2 send CP-DATA/RP-ACK for MT SMS on DTAP, 3.2.1 expect MT-ForwardSM-Res for MT SMS on GSUP.

2019-01-29BSC_Tests: Add tests to check channel allocatorPhilipp Maier2-0/+304
When a channel is assigned via the assignment request throught the A interface, the MSC may offer either FR, HR or both. When FR and HR are permitted, a preference is set on one of the two. At the moment we do not check how the bsc is reacting to those preferences and its also not checked how the behavior is when the preferred rate is not available because all lchan of that type are already in use. Lets add a set of tests to verify this. Change-Id: I109d986dd7ece1a56422a669ca64353ed46f7ed6 Depends: osmo-bsc I397e68e26d6a1727890353fa34f4897b54795866 Related: OS#3503

2019-01-22MSC_Tests: individual IMSI for TC_lu_and_mt_sms_paging_and_nothingPhilipp Maier1-1/+1
The testcase TC_lu_and_mt_sms_paging_and_nothing is currently using an IMSI that ends on 43. The same IMSI is used by TC_mo_cc_bssmap_clear as well. Since TC_lu_and_mt_sms_paging_and_nothing is running before TC_mo_cc_bssmap_clear, the re-use of the IMSI triggers the MSC to continue the paging procedure. The MSC then eventually tries to deliver the SMS from TC_lu_and_mt_sms_paging_and_nothing. This will disturb the execution of TC_mo_cc_bssmap_clear, which then fails. Lets make sure that TC_lu_and_mt_sms_paging_and_nothing uses an individual IMSI that is never used again throught the execution of the testsuite.

2019-01-12BTS_Tests.ttcn: fix: use TRXC interface of the BTS side, not BBVadim Yanitskiy1-20/+20
It was observed that 'BTS_Tests.TC_rach_max_ta' started to fail with the following reason: "BTS_Tests.ttcn:1091 : RACH passed but was expected to be dropped: -2560". My initial assumption was that the test case basically sends FAKE_TOA command on a wrong TRXC interface, and it was confirmed using # TRXD of the BB side $ ./ -p 6700 [DEBUG] L1 -> TRX burst: fn=616 tn=0 pwr=0 [DEBUG] TRX -> L1 burst: fn=597 tn=0 rssi=-60 toa256=-2560 [DEBUG] TRX -> L1 burst: fn=598 tn=0 rssi=-60 toa256=-2560 ... # TRXD of the BTS side (Uplink bursts only) $ ./ -p 5700 --direction L1 [DEBUG] TRX -> L1 burst: fn=719 tn=0 rssi=-60 toa256=0 and additionally be enriching logging messages of [DEBUG] (trx@ Recv FAKE_TOA cmd Sending FAKE_* commands on TRXC interface of the BB side affects the bursts being forwarded to this side, so we should use the TRXC interface of the BTS side to simulate Uplink delay. The reason why the test case has been passing some time ago is that there was a bug in, that has been fixed recently.

2019-01-07MSC_Tests: make sgsap interface optionalPhilipp Maier2-6/+18
At the moment the sgsap always enabled in the testsuite. This means the testsuite will try to connect the SGs interface of osmo-msc on initalization. If the connection fails, the testcase will fail also. Unfortunately the related patches that add the SGs interface to osmo-msc are not yet merged to master. This causes almost all testcases to fail, so lets have the SGs interface as an option that we can switch on when the SGs interface patches are merged to master.

2018-12-23BTS_Tests: Verify RSL MS POWER CONTROL and SACCH MS POWER LEVELPhilipp Maier3-1/+84
Usually the MS power is controlled by the BTS and there is no continous supervison by the BSC needed. However, a scheme where the BSC takes care of the power control loop exists. The power is then set via RSL using an RSL MS POWER CONTROL message. This tests establishes a dchan and then sends MS POWER CONTROL messages with differen power levels and then checks the presence of the power level set in the MS POWER LEVEL field of the SACCH L1 header.

2018-12-23mgw: Tear down all RTP flows to avoid race condition on tear downDaniel Willmann1-0/+2
When stopping the test TC_two_crcx_and_unsolicited_rtp the unsolicited RTP stream is not stopped. As a result it could happen that between tearing down the other flows and stopping the test an unsolicited RTP packet is sent to a closed socket. The resulting ICMP destination unreachable packet translates to a "Connection refused" error on the sending socket and fails the test. Avoid this by making sure the unsolicited RTP sender is stopped before stopping the test. Change-Id: Ied839596589609e75fa487046a85db48991e4c73

2018-12-02library/GSUP_Types.ttcn: add MO-/MT-FORWARD-SM messagesVadim Yanitskiy1-3/+433
According to 3GPP TS 29.002, there are two services: - MAP-MO-FORWARD-SHORT-MESSAGE (see 12.2), - MAP-MT-FORWARD-SHORT-MESSAGE (see 12.9), which are used to forward MO/MT short messages. This change replicates both services as GSUP messages: - OSMO_GSUP_MSGT_MO_FORWARD_SM_*, - OSMO_GSUP_MSGT_MT_FORWARD_SM_*. Please note, that only the 'must-have' IEs are introduced by this change, in particular the following: - OSMO_GSUP_SM_RP_MR_IE (see note below), - OSMO_GSUP_SM_RP_DA_IE (see, - OSMO_GSUP_SM_RP_OA_IE (see, - OSMO_GSUP_SM_RP_UI_IE (see, - OSMO_GSUP_SM_RP_MMS_IE (see, - OSMO_GSUP_SM_RP_CAUSE_IE (see GSM TS 04.11,, where both SM_RP_DA and SM_RP_OA IEs basically contain a single nested TLV of the following format: - T: identity type (see 'GSUP_SM_RP_ODA_IdType'), - L: identity length, - V: encoded identity itself. According to GSM TS 04.11, every single message on the SM-RL has an unique message reference (see 8.2.3), that is used to link an RP-ACK or RP-ERROR message to the associated (preceding) RP-DATA or RP-SMMA message transfer attempt. In case of TCAP/MAP, this message reference is being mapped to the Invoke ID. But since GSUP has no 'Invoke ID' IE, and it is not required for other applications (other than SMS), this change introduces a special 'SM_RP_MR' IE that doesn't exist in MAP.

2018-11-29MSC_Tests.ttcn: introduce TC_lu_and_ss_session_timeoutVadim Yanitskiy2-0/+74
The idea of this test case is to verify SS session termination due to expiry of its guard timeout. The timeout value is intentionally set to a few seconds in order to speedup test case execution (we don't want to wait 2 minutes). We expect OsmoMSC to inform both session entities (MS and EUSE) about timeout expiry before releasing the transaction. The MS should receive GSM 04.80 RELEASE COMPLETE message with optional cause, while the EUSE should receive OSMO_GSUP_MSGT_PROC_SS_ERROR. At the moment, it's not clean which cause values should be used: - for GSM 04.80 RELEASE COMPLETE the cause IE is optional, and possible values are defined in GSM TS 04.08, annex G-H. The H.6.7 Cause No. 102 "recovery on timer expiry" seems to be suitable; - for OSMO_GSUP_MSGT_PROC_SS_ERROR the generic cause IE could be used, but actually this IE is not generic at all, and limited by 'gsm48_gmm_cause' enum; so we temporarily expect arbitrary cause values in both messages.

2018-11-29library/GSUP_Types.ttcn: fix IE order in PROC_SS_ERROR templatesVadim Yanitskiy1-4/+4
In general, the order of IEs in a GSUP message doesn't matter. Despite libosmocore's GSUP API encodes IEs in a fixed order, it is capable to decode them in any arbitary order. Meanwhile, in the current TTCN-3 definitions (i.e. templates) the order makes a difference, because the 'GSUP_IEs' type is a record, that according to the TTCN-3 documentation represents an *ordered* sequence of elements. Let's reorder the IEs of both t{r|s}_GSUP_PROC_SS_ERR templates in a way that is used by the libosmocore's GSUP encoder. This correction doesn't affect successful test case executions, because we don't test possible problematic situations yet. But if something went wrong on the HLR side (i.e. SUT), the matching statements wouldn't match the PROC_SS_ERR message correctly and continue to wait until the guard timer is expired.

2018-11-29library/GSUP_Types.ttcn: fix missing session state IE in PROC_SS_ERRVadim Yanitskiy2-4/+8
Both session state and session ID IEs are always being encoded together by libosmocore's GSUP implementation. So, if a message contains a session ID IE, session state IE shall also be there. For some reason, the session state IE was missing in both ts_GSUP_PROC_SS_ERR and tr_GSUP_PROC_SS_ERR templates. This could led to incorrect matching in our test cases. This change fixes both templates by adding the missing IE. Since tr_GSUP_PROC_SS_ERR templete is used in HLR_Tests.ttcn, all the affected matching statements were also corrected. This correction doesn't affect successful test case executions, because we don't test possible problematic situations yet. But if something went wrong on the HLR side (i.e. SUT), the matching statements wouldn't match the PROC_SS_ERR message correctly and continue to wait until the guard timer is expired.
