We already have TC_cmserv_imsi_unknown, but lack a test that shows CM Service
Request behavior for an unknown TMSI.
Looking at OS#4721 I vaguely expected an ID Request to also happen during CM
Service Request, but instead we reject the unknown TMSI completely, and require
the MS to perform a proper LU subsequently.

Unfortunately, I could not find a way to encode such an invalid

figured out that '000'B also crashes OsmoMSC.
MM Identity Request is triggered by initiating an Update Location

Originally/recently, osmo-msc did not validate the IP addresses at all. In an

* Semantic:
We don't really know which side the MSC first creates a CRCX for. Instead of
assuming that the RAN side is always CRCX'd first, simply handle a "first" and
a "second" CRCX, not making any assumptions which is for which side.
Notably, there still are quite a few places assuming which CRCX corresponds to
the RAN/CN side, but the changes are sufficient to still pass the tests when
osmo-msc swaps the CRCX order; sometimes for slightly obscure reasons, for
example because it doesn't matter that the wrong port number is returned during
a subsequent MDCX... Cleaning up the rest is still todo for later.
Remove code dup from call establishing code, particularly for MGCP.
Use f_mo_call_establish() and f_mt_call() where ever possible, to make all of
the call establishing tests handle upcoming changes in osmo-msc's order of
messages, without re-implementing the changes for each test individually.
The X-Osmux parameter was so far expected to appear in the first CRCX received,
assuming that this first CRCX is for the RAN. Instead, detect whether X-Osmux
is contained in a CRCX, and reply with an Osmux CID if so, regardless of it
being the first or second CRCX. Count the number of X-Osmux parameters
received in CRCX messages, and compare after call setup to verify X-Osmux
presence.
Since f_mo_call_establish() can't handle RANAP assignment, a few Iu tests that
worked with the older code dup will break by this patch. This is fixed by a
subsequent patch, see I0ead36333ab665147b8d222070ea5cf8afc555ec.
* Details, per patch chunk:
Change ts_BSSMAP_IE_AoIP_TLA4 to a non-value template, so that we can use a
wildcard for the assigned port number from MGCP (depending on RAN or CN CRCX
first, the RAN port number can be one or the other).
In CallParameters, move MGCP handling instructions into a separate record
"CrcxResponse", and have two of them for handling the first and the second
CRCX, replacing mgw_rtp_{ip,port}_{bss,mss} and mgcp_connection_id_{bss,mss}.
In CallParameters, add some flags for early-exiting call establishment with a
particular desired behavior, for specialized tests.
In CallParameters, use common default values and don't repeat them in each and
every call establishing test.
Set cpars.mo_call := {true,false} implicitly when f_{mo,mt}_call_establish()
are invoked.
Remove CRCX comments implying RAN or CN side, instead just talk of the "first"
and the "second" CRCX.
Implement one common f_handle_crcx() function, which is used by
f_mo_call_establish(), f_mt_call_complete(), as_optional_mgcp_crcx(), and
implicitly uses the first/second CRCX handling.
For Assigment, use a wildcard RTP port so that we don't have to assume which
CRCX was for the RAN side.
In f_mo_call_establish(), insert special case conditions to make it enact
errors at specific times, for individual tests. That saves re-implementing the
entire call establishment (code dup).
For error cases, add expectation of a CC Release message in the call
establishment. This should not apply for normal successful operation, but
because interleave does not support conditionals, add flags
got_mncc_setup_compl_ind and got_cc_connect to break the interleave when
establishing is complete, so that the CC Release is skipped.
A CC Release always breaks the interleave, at whatever time it arrives.
Tests adopting f_{mo,mt}_call instead of code dup:
f_tc_mo_setup_and_nothing()
f_tc_mo_crcx_ran_timeout()
f_tc_mo_crcx_ran_reject()
f_tc_mo_release_timeout()

- Fix error log for a missing final DTMF.
- Instead of code dup to establish a call, use f_mo_call_establish(). This
will make the test benefit from changes to f_mo_call_establish() (which will
soon come up to accomodate changes in osmo-msc's codec negotiation).
- Instead of hardcoding the expected N_SD counter values to detect DTAP
duplicates, use f_bssmap_last_n_sd() and f_next_n_sd(), so that the N_SD
counter is correct regardless of how many DTAP were sent in
f_mo_call_establish().
- Instead of hardcoding a correct N_SD in the end, use skip_seq_patching ==
false, so that the ttcn DTAP correctly tracks N_SD for subsequent call
release messages.
- Release the call.

Before this, if an Assignment Request contains an unexpected Transport Layer
Address, the test completely rejects the Assignment Request.
Instead, accept any tla in the Assignment, and compare the expected tla in the
Assignment's interleave action. Thus we directly get logging hinting at the tla
instead of a T_guard timeout.

Sometimes in TC_proc_ss_paging_fail we hit a race condition. The
problem is that the paging expiration timer in OsmoMSC is set to

Let's increase our timer value to 20.0 seconds,

2. Network-originated connection establishment:

We were using '?' for the protocolExtensions in RANAP messages,
which required that such extensions existed. In reality, we want
to use '*' which accepts paging messages whether or not there
are any protocolExtensions present. As this is the default in
all our RANAP receive template, callers don't even need to specify
it.
This should fix all Iu paging related test failures in MSC_Tests*.ttcn

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
and what hasn't.

This function is required not only for the MSC_Tests, but also for
the upcoming Iu related SGSN tests

This might look a bit like copy+paste programming for our testcases.
However, we actually want the Iu related tests show up as separate
'testscase' in the TTCN-3 sense, so there's no way that's more elegant
than this :/

The new function will check the RAN type and dispath to
f_bssap_compl_l3() in case of 2G/GERAN and to f_ranap_initial_ue()
on case of 3G/UTRAN.

The RAN_Emulation currently unconditionally provides BSSAP and MGCP support.
Let's re-structure the code so that support for those protocols is now
possible to enable/disable at compile time.
This patch is in preparation of introducing RANAP support in RAN_Emulation.

This allows to start ConnHdlr on specific RAN connections, i.e.
on different emulated BSCs (and soon RNCs).

So far, BSSMAP_Emulation supported only a transport over BSSMAP.
However, we soon intend to merge support for RANAP in order to
simulate RANAP/Iu connections as well as BSSMAP. Let's start
by renaming some of the existing types/functions/ports/modules
without introducing any functional changes just yet.

An MSC might decide to repeatedly retry Paging if it failed the first time, but
osmo-msc currently has no such mechanism. Instead, it so far had a bug that
retriggered a failed Paging from a start in a situation where there are SMS
pending for only one subscriber, and sending the SMS fails. osmo-msc patch
I24bf9f1c1167efe1080ae4cf47ed2ef0bd981e49 changes this behavior to accept a
Paging failure and not launch the same SMS again numerous times.
Adjust the tests to this new behavior.
Depends: I24bf9f1c1167efe1080ae4cf47ed2ef0bd981e49 (osmo-msc)
