When f_expect_chan_rel() is called after receiving the BSSMAP
RESET and DISC.ind f_expect_chan_rel() is called. The flush
parameter is not set, which means the default flush = true is
valid. This leads into an early flush of the RSL Queue and
tosses the RSL RELEASE REQUEST we expect, so the test can not
pass, even when the BSC sends the RLEASE REQUEST.
Looking further up in the code. IPA_RSL[0].clear is called,
so the Queue is flushed to get rid of unwanted messages from
the IMMEDIATE ASSIGN. There is no need to flush the queue
a second time anyway.
- Do not flush the RSL queue, set flush=false when calling
f_expect_chan_rel()

When we page an unknown/unsupported CellIdentifier format, OsmoBSC
decides to page on all BTSs to be safe. This way we have a chance of
making communication happen, rather than breaking it.

We now test all of the cell identification types specified in BSSMAP,
and also lists with a length != 1 entry.

We have to wait for sime time until some RSL paging command would have
arrived, rather than continuing too quickly.

During assignment or hand-over, a given TTCN-3 component may be
interested in registering more than one channel number. Add an explicit
procedure port with associated registration procedure, similar to what
we already do in GSUP, MNCC and others.

The point of this test is to verify that *no* paging messages are sent
if "No cell" is given as cell identifier list by the MSC. We can thus
not use the existing pageing_helper function, but have to handle this
a bit differently.
This makes TC_paging_imsi_nochan runs pass.

This test case was incomplete in that it didn't account for a RLL REL
REQ/RESP before RF_CHAN_REL.
Together with OsmoBSC Change-Id

This test case was incomplete in that it
* applied the wrong timeout T3101 instead of T3210
* didn't account for a RLL REL REQ/RESP before RF_CHAN_REL
Let's fix it. Together with OsmoBSC Change-Id
Ie11d7d06353ba1b1e2fab6763dd7b032ce8a5d2c this check now actually
passes for the first time.

In OsmoBSC Change-IdI68286d26e2014048b054f39ef29c35fef420cc97 we
introduce a proper subscriber connection state machine which fixes
the order of events during channel release after connection failure.

When Change-Id I10fc9f60c58c6b7ed424a86ce23bf6b9802c9eb1 was merged,
OsmoBSC started to always allocate SDCCH first, no matter what the
establishment cause. This basically means we don't do very early
assignment anymore. TC_exhaustion must be adapted to allocate all
SDCCH and all TCH before failing.

Don't expect the ASSIGNMENT to fail in case of unsupported A5/4,
but expect a CIPHERING MODE REJECT.

Let's verify the operation of the CIPHERING MODE COMMAND as issued
by MSC, performed by BSC and implemented by simulated BTS/MS.

This way we benefit from the ability to handle the RR MODE MODIFY,
RSL MODE MODIFY, IPA CRCX and IPA MDCX capabilities of the MSC_ConnHdlr
component. While each test case now needs a separate function in
addition to the actual testcase, this allows for more flexibility
and a more complete emulation of BTS behaviour.
Change-Id: Iba50663cb5104bf34bd6fc8aac2aa3b47155fe99
Using the MSC_ConnHdlr component, we can now handle the BSSAP (MSC)
and RSL (BTS) side of a single radio channel.
Change-Id: I00dcf1e4eaa7f133788cc01fbbcd4148a0258ef4
The existing tests were implemented directly on top of the BSSMAP
and RSL CodecPorts. If we loop in the RSL_Emulation and
BSSMAP_Emulation components, we can properly multiplex/demultiplex
multiple MS (radio channels) on both the RSL and the MSC (SCCP
connection) side.
In order to have a single component that handles both the RSL and the
BSSAP side of a given channel/subscriber/call, we introduce the concept
of BSSMAP "Expects", where the test csse can register the L3 INFO that
it sends in the RLL ESTablish INDication on the RSL side, so the BSSMAP
handler cna route the BSC-originated SCCP connection with that L3 INFO
back to the same component. This is a bit inspired "in spirit" of the
"expect" mechanism of netfilter connection tracking.

We ensure that all channels are allocated, and that the first allocation
beyond the avialable channels will fail and generate an IMM_ASS_REJ.
WE also verify that the related counters are incremented as expected.

This allows us to verify if the BSC pages *only* where it is supposed
to page based on the cell identity list in the 08.08 PAGING.
