Vadim Yanitskiy eb57062ab8 library/GSM_RR_Types.ttcn: fix 'presence' in tr_PacketUlSglAssign
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.

Vadim Yanitskiy 6edd4f5a06 library/GSM_RR_Types.ttcn: introduce generic tr_IMM_TBF_ASS
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.
Let's add a generic template for Packet Immediate Assignment
and allow passing IaRestOctets as a parameter.

Vadim Yanitskiy 7091e8de88 library/GSM_RR_Types.ttcn: refactor IaRestOctHH coding
According to 3GPP TS 44.018, section 10.5.2.16, IA Rest Octets IE
starting with 'HH' bits may contain one of the following CSN.1
encoded components:

  7 6 5 4 3 2 1 0  Bit Numbers
  H H 0 0 . . . .  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.

Vadim Yanitskiy a4aacc2179 library/GSM_RR_Types.ttcn: fix: apply '2B'O padding to GsmRrMessage
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.

Vadim Yanitskiy 9b2a3e8cb8 library/GSM_RR_Types.ttcn: fix ImmediateAssignment coding regressions
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.

Vadim Yanitskiy 1f4486cfe3 library/GSM_RR_Types.ttcn: fix: IA Rest Octets may have optional padding
According to 3GPP TS 04.08 (version 7.21.0), section 10.5.2.16 and
table 10.5.45, IA Rest Octets IE may contain spare bits. Let's add
an optional field 'pad' to record 'IaRestOctets'.

NOTE: somehow this change crashes my TITAN runtime:

  dec_GsmRrMessage(): Stream before decoding: '2D063F100FE3673A096B0000C800300B2B2B2B2B2B2B2B'O
  *** Error in `././PCU_Tests': malloc(): memory corruption: 0x000000000074a790 ***

while the recent version works just fine.

Octets (see 10.5.2.16) is a mandatory IE, not optional.

Stefan Sperling 59c15d67ca resolve ambiguity of MobileIdentityLV type name
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.

Harald Welte e8d750e668 bts: More complete AGCH / IMM.ASS testing
The existing test simply sent 1000 messages via RSL without checking
what actually arrived on the radio interface, or without
expecting/counting any RSL DELETE IND.

Let's fix this by introducing test sending IMM.ASS at three different
rates, with related expectations in terms of nubmer of IMM.ASS arriving
on Um vs. RSL DELETE IND arriving at BSC.
