Both f_mo_call_establish() and f_mt_call_establish() were testing barely half a
voice call setup. For example, f_mo_call_establish() used to be satisfied with
just two CRCX, but no actual RTP connections being made.
Add numerous MNCC and MGCP messages more closely resembling an actual call.
The main reason is to achieve a state that passes both current osmo-msc master
as well as the upcoming inter-MSC Handover refactoring.
Add log markers to f_*_call_*(): often when a test halts, it is not at all
clear why. With these log markers it is saner to figure out what has happened

This patch introduces protocol codecs for the HNBAP, RUA and RANAP
protocols, which is mandatory for testing IuCS, IuPS or Iuh in

As Eclipse TITAN ASN.1 only supports the BER codec and the above

APER to BER and vice-versa. This was implemented using a proprietary

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 7.6.8.1),
- OSMO_GSUP_SM_RP_OA_IE (see 7.6.8.2),
- OSMO_GSUP_SM_RP_UI_IE (see 7.6.8.4),
- OSMO_GSUP_SM_RP_MMS_IE (see 7.6.8.7),
- OSMO_GSUP_SM_RP_CAUSE_IE (see GSM TS 04.11, 8.2.5.4),
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.

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.

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.

and convert them to a log string f_shutdown expects one charstring.

There are two distinct types defined for a Mobile Identity LV IE.
One type definition lives in GSM_RR_Types and defines the "canonical"
IE form, with a full octet for the length.
Another one lives in RLCMAC_CSN1_Types which defines how a mobile
identity appears in paging requests. In this case, the length field
is only 4 bits in size. Rename this latter type from MobileIdentityLV to
MobileIdentityLV_Paging and add a comment to highlight this distinction.
TS 144 060 Table 11.2.10.2 explicitly states that only the value
part of this IE matches the definition of the canonical IE as
"defined in 3GPP TS 44.018" (actually, TS 44.018 further redirects
the reader to TS 124 008; see section 10.5.1.4 there).
As an aside, a third definition of the MobileIdentityLV type exists
in MobileL3_CommonIE_Types, which matches the "canonical" form.

This new module allows us to test IPA code in libosmocore
and libosmo-netif. Currently only one test is implemented,
which sends a chopped IPA ping message and expects to receive
an IPA pong.
The system under test is any IPA speaker on any TCP port.
Any test suite may call parametrized functions to create
an IPA testing component and run a particular test.
So far, one such test has been added to the BSC_Tests suite.

From libosmo-sccp.git Icffda98579e676ab6ca63c9c22cf5d151c4fe95f on, we expect
an IPA ID ACK upon first connecting, not an IPA ID GET. This might be specific

Make the IPA server in IPA_Emulation configurable, to conform and send the IPA
ID ACK upon connecting. This fixes the ttcn3-bsc-tests,SCCPlite suite, broken
by above libosmo-sccp commit.
For other IPA clients, it is so far required to send the IPA ID GET, so only

Our TTCN3 implementation of the IPA multiplex with CCM handshaking
has been based on some wrong assumptions about the protocol logic.
To make the code stricter, we
* send an ID_ACK immediately after connecting TCP in a client
* separate client and server CCM responder logic
* always respond with ID_ACK to ID_RESP (we accept any identity)
Also, as the Osmocom CTRL interface uses an IPA multiplex but no CCM,
we introduce a boolean variable (and function argument) to clearly
enable/disable CCM support in a given IPA_Emulation component. The

The MDISC_IPACCESS is only used for the media (CRCX/MDCX/DLCX) related
commands, not for the PDCH activation/deactivation. The latter uses
normal MDISC_DCHAN.
Also, add the inverse templates for PDCH actiation/deactivation, so we
now have both receive and transmit template for each of the 6 related
messages (activation, deactivation, plus each their ACK + NACK).

The existing MGW tests were entirely on the MGCP side. Let's start
some tests that exchange RTP frames with the MGW and validate that
the MGW can actually act on what is configured via MGCP.

In order to form a minimal HANDOVER REQUIRED message additional
Templates (ts_) are needed.
- Add Template ts_BSSMAP_IE_SpeechVersion
- Add Template ts_BSSMAP_IE_CurrentChannelType1
- Add Template ts_BSSMAP_IE_OldToNewBSSInfo

The upcomming tests for inter-BSC handover make it necessary to
simulate multiple (two) BSCs to the MSC, while the current
Implementation can only handle one BSC instance at a time.
- Allow multiple BSC instances to be created
- Add a simple reset-test to test what happens when
two BSC instances are started (BSSMAP reset from two
different BSCs)

The TTCN-3 data types are abstract data types, Encoding artefacts
like 'F' for padding shouldn't be seen by the user. Hence, let's
pass a 2-digit-long or 3-digit-long hexstring into the encoder
functions and let them determine if they should introduce any 'F'
for padding or not.

Add general infrastructure to
- pass an MCC-MNC for BSSGP to use into f_init();
- verify that the Attach Accept PLMN matches the BSSGP one.
Add TC_attach_mnc3() to feed an MNC with three digits and a leading zero, to
verify the recent mnc3 patches. When testing against a libosmocore and
osmo-sgsn before mnc3, this results in:
Test case TC_attach_mnc3 finished. Verdict: fail reason: "mismatching PLMN in Attach Accept: 02342F; expected 023042"
With the current master branches the proper 3-digit MNC with leading zero is
fed back into the Attach Accept message.

The cell identifier used by the paging tests is 001-01, i.e. uses a
2-digit MNC. With the introduction of 3-digit MNC support in osmo-bsc,
the paging tests became incompatible with a osmo-bsc config with:
network country code 1
mobile network code 1
Explicitly declare a Cell_Identity with 2-digit MNC (includes an 'f').
Also, fix f_enc_mcc_mnc to properly encode 2-digit MNC values.

Whenever the OPTIONAL<> construct is used for a member of a record,
we have to add an extra set of parenthsis in order to avoid bogus
"has no RAW decode method" error messages.
It seems the OPTIONAL inherits from Base_Type which will print
"which has no RAW decoding method" from its RAW_decode().

The existing BTS testing code was based on a ~1 week old version
of trxcon+fake_trx from osmocom-bb.git fixeria/trx branch, which
has meanwhile evolved:
* port number change for TRX protocol
* FAKE_TIMING -> FAKE_TOA
* we can now expect responses to our UDP control commands
Let's adapt the testsuite to those changes

TITAN will print warnings if a still-running timer is res-started.
It will also warn if a not-started timer is stopped, so we need
