According to 3GPP TS 44.018, section 10.5.2.16 "IA Rest Octets", the first bit of Packet Uplink Assignment defines whether it is a dynamic (1) or single block (0) allocation. Change-Id: If2bee9b1b065fcfedd0e57a6487040cefe2e50c5
2019-09-29PCU_Tests_RAW.ttcn: TC_cs_lqual_ul_tbf: properly check for Dynamic AssignmentVadim Yanitskiy1-1/+6
According to 3GPP TS 44.018, section 10.5.2.16 "IA Rest Octets", Packet Uplink Assignment can be either of the following types: - single block allocation, - dynamic allocation. The current version of TC_cs_lqual_ul_tbf does not handle single block allocation, so we need to make sure we got a TBF with dynamic allocation. Change-Id: I05cf0c62d21094fb53a9e5e54b404f3cf972a182

This change introduces a new test case TC_cs_lqual_ul_tbf, which is aimed to test the feedback of OsmoPCU on changing link quality measurements in Uplink Data blocks during an active TBF. Change-Id: Ia78d93e43a3c41b0b30e70df20a2da31077fd05f Related: SYS#4607
2019-09-27PCU_Tests_RAW.ttcn: introduce TC_ta_rach_imm_ass to test initial TAVadim Yanitskiy1-0/+78
The aim of this test case is to test the correctness of Timing Advance at the time of TBF establishment. In particular, the test case sends several Access Bursts (RACH.ind) with increasing 'qta' value, what causes OsmoPCU to allocate a TBF (Temporary Block Flow) for each RACH.ind and send DATA.req with Immediate Assignment on AGCH, containing the expected Timing Advance value.

2019-09-27library/PCUIF_CodecPort.ttcn: strip padding bytes from PCUIF_dataVadim Yanitskiy1-0/+10
In Ieefa61232eb215a19a02e490255332e28e23b8f8, I had to revert I5808954b5c67c3239e795e43ae77035152d359ef, because that change broke encoding of messages on the PCU interface. Since we cannot use 'PADDING' attribute until its implementation is fixed in TITAN, let's work this around by stripping padding bytes manually in UD_to_PCUIF().

2019-09-27Introduce PCUIF, BTS and ClckGen components for RAW PCU test casesVadim Yanitskiy3-0/+483
The problem of existing test cases is that they mix IUT (i.e. OsmoPCU) with OsmoBTS (osmo-bts-virtual) and OsmocomBB (virt_phy). This approach allows to avoid dealing with TDMA clock indications and RTS requests on the PCU interface - this is done by OsmoBTS. On the other hand, our test scenarios may be potentially affected by undiscovered bugs in OsmoBTS and the virt_phy. In order to solve that problem, this change introduces a set of new components and the corresponding handler functions: - RAW_PCUIF_CT / f_PCUIF_CT_handler() - PCU interface (UNIX domain socket) handler. Creates a server listening for incoming connections on a given 'pcu_sock_path', handles connection establishment and message forwarding between connected BTS components (see below) and OsmoPCU. - RAW_PCU_BTS_CT / f_BTS_CT_handler() - represents a single BTS entity, connected to OsmoPCU through the RAW_PCUIF_CT. Takes care about sending System Information 13 to OsmoPCU, forwarding TDMA clock indications from a dedicated ClckGen component (see below), and filtering the received messages by the BTS number. Implements minimalistic scheduler for both DATA.ind and RTS.req messages, so they are send in accordance with the current TDMA frame number. - RAW_PCU_ClckGen_CT / f_ClckGen_CT_handler() - TDMA frame clock counter built on top of a timer. Sends clock indications to the BTS component. All components communicate using TTCN-3 ports and explicitly defined sets of messages (see RAW_PCU_MSG_PT). One noticeable kind of such messages is events (see RAW_PCU_Event and RAW_PCU_EventType). That's how e.g. the PCUIF component can notify the BTS component that OsmoPCU has just connected, or the BTS component can notify the MTC that SI13 negotiation is completed. Events may optionally have parameters (e.g. frame-number for TDMA_EV_*). Furthermore, the proposed set of components allows to have more than one BTS entity, so we can also test multi-BTS operation in the future. +-----+ +----------+ +---------+ | MTC +---------------+ PCUIF_CT +------+ OsmoPCU | +--+--+ +----+-----+ +---------+ | | | | | | | +-----------+ | +---------------+ +----+ BTS_CT #1 +------+ | ClckGen_CT #1 | | +-----+-----+ | +-------+-------+ | | | | | +---------------------------+ | | | +-----------+ | +---------------+ +----+ BTS_CT #2 +------+ | ClckGen_CT #2 | | +-----+-----+ | +-------+-------+ | | | | | +---------------------------+ | | | +-----------+ | +---------------+ +----+ BTS_CT #N +------+ | ClckGen_CT #N | +-----+-----+ +-------+-------+ | | +---------------------------+ Change-Id: I63a23abebab88fd5318eb4d907d6028e7c38e9a3

For me this change causes MGCP parsing errors: setverdict(fail): pass -> fail reason: "Could not extract parameters for code "C"" Apparently the \r is after all necessary to parse MGCP.

Both 't_IMM_ASS_TBF_DL' and 't_RR_IMM_ASS_TBF_DL' templates were introduced for a specific task - matching Packet Immediate Assignment (Downlink TBF) by TLLI. In the upcoming changes we will also need to match Uplink TBF assignment, and more generic fields such as Timing Advance.

Packet Uplink Assignment H H 0 1 . . . . Packet Downlink Assignment H H 1 . . . . . Second Part Packet Assignment We already have (partial) support for the first two, while the last type has not been supported so far. Let's add it. Also, this change introduces several templates for IA Rest Octets IE and some of its components mentioned above. This would allow us to abstract the API users from dealing with further changes, e.g. adding a coding attribute 'CSN.1 L/H' and missing fields. Change-Id: Ib3a21e7c5fa1cad4466e3a09fa70540de7f6ecc5
2019-09-09library/GSM_RR_Types.ttcn: fix: apply '2B'O padding to GsmRrMessageVadim Yanitskiy1-3/+5
For some reason TITAN starts padding not from the beginning of record ImmediateAssignment, but from it's wrapper GsmRrMessage. As a result, dec_GsmRrMessage() warns about undecoded octets: Data remained at the end of the stream after successful decoding '2B2B2B'O Similarly enc_GsmRrMessage() generates a shorter payload. Let's work this around by applying PADDING attribute to GsmRrMessage. Change-Id: I5fe327383402956213c20a68b18b8a48381156b5

Since I403d2141536303a966be7ff51b06c3de202412e6, IA Rest Octets is a mandatory IE. When changing the definition of ts_IMM_ASS, I forgot to mark its optional 'lh', 'hl', and 'hh' as omitted explicitly. As a result, many of our TTCN-3 test cases were broken: Dynamic test case error: Using an unbound optional field. Also, in Ifdcdcf50709fcc03195cb8ef6092977e26f910ec I added an optional field 'pad' to record 'IaRestOctets'. That was not the best solution, because padding should be handled transparently. Let's get rid of that dummy field and equip both 'ImmediateAssignment' and 'IaRestOctets' records with proper padding attributes. The later one needs to be marked with 'CSN.1 L/H' attribute in the future, but for now we should keep it octet-aligned. Change-Id: I69d5fbd8e3388e287bfa54f02454d207e62ee640

2019-09-05library/PCUIF_Types.ttcn: inform RAW codec about PADDING in PCUIF_dataVadim Yanitskiy1-2/+7
PADDING is one of the TITAN specific language extensions [1], which tells the RAW codec that an encoded payload shall end at a boundary fixed by a multiple of 'padding' unit bits counted from the beginning of the message. Let's use it for record 'PCUIF_data', where the fixed-size buffer is located in between the other fields, so padding will be ignored by the RAW coding after decoding: $HOST: dec_PCUIF_Message(): Decoded @PCUIF_Types.PCUIF_Message: { msg_type := PCU_IF_MSG_DATA_REQ (0), bts_nr := 0, spare := '0000'O, u := { data_req := { sapi := PCU_IF_SAPI_AGCH (2), len := 23, data := '2D063F100FE3673A096B0000C800300B2B2B2B2B2B2B2B', ... } } } As a result, we don't have to deal with padding manually and can safely use 'decmatch' statement in the receive templates.

2019-09-05CBSP: Hack to make receive templates workHarald Welte1-5/+5
For some reason, the 'ifpresent' annotation doesn't work in lists of templates. This means we have to re-think the CBSP template structure at some point. However, this would be a significant detour and I'd rather have working tests right now, so we can verify the actual functionality merged into the BSC right now.
