In addition to SI 2 and SI 5, the SI 2ter and 2bis is generated, if
neighbour cells in other bands exist. Also it is indicated in the rest
octets of SI3, that SI 2ter is used. If no neighbour cell in a different
band exists, the SI 2ter and SI 5ter is omitted.
A special case is P-GSM range (channels 1-124). To be compatible with
older phones, SI 2bis and SI 5bis is used. If the BCCH lays inside the
P-GSM band, only neighbour cells of the P-GSM range are included in
SI 2 and SI 5. If neighbour cells exist in the same band (900), but lay
outside the P-GSM range, the SI 2bis and SI 5bis is used to extend the
list of neighbour cells. The extension is also indicated in SI 2 and
SI 5. If the BCCH lays inside the P-GSM range, but no neighbour cell
exists in the same band outside the P-GSM range, the SI 2bis ans SI 5bis
are omitted.

strstr() was used with wrong argument order, causing it to always match,
and causing an invalid response to a variety of different SS and USSD
requests.
This has apparently caused havoc among a number of HTC phones which
issue SS requests without user interaction upon boot, and then trip over
our inappropriate response.

This must have been obsoleted by the move to libosmo-abis.

Introduce a SS_CCCH for the paging and the rach load. The paging

I'm sure I read somewhere that it actually was 0..1024, as I kept
wondering how stupid it was to use 10bit+1. However, that source
was incorrect, as GSM TS 05.05 quite clearly states 0..1023

When we get an assignment command from the MSC, we no longer have to
check statically for certain codecs, as we have a vty-configured list of
codecs that is checked just below.
|
|
|
|
This allows the use of the existing "call-agent ip A.B.C.D" command in
libmgcp in order to set a default destination address of the call agent.
This is required as a pre-condition for certain call agents (like the
zynetix MSC) that require a RSIP from the BSC to the MSC as the initial
MGCP message.
|
|
The second test case (CRCX_ZYN) fails as the message is not compliant
with the spec. However, our parer should be more tolerant, just in
case...
|
|
use a data-structure driven approach
|
|
|
|
RR Messages like STATUS, GPRS SUSPEND, HANDOVER COMPLETE/FAIL, ...
should be processed on the BSC side of things, not on the MSC side.
This is among other things required in preparation of intra-BSC
hand-over support in osmo-bsc.
|
|
This prevents osmo-bsc from sending RR messages to the MSC and rather
process them inside the BSC and turn them into BSSAP CM UPDATE.
|
|
the TMSI is a uint32_t big-endian value and not a gsm 04.08 mobile
identity like the IMSI.
|
|
|
|
|
|
Internationalize the number like we do it for Call Control. Update
the test result to match this new behavior.
|
|
Introduce number rewriting of SMS-SUBMIT. Introduce a new list,
move code around to help with finding a new number, somehow the
number encoding for TP-DA is borked, 03.40 references 04.11 but
the length appears to be strlen(number) without taken the type
field into account.

In case of a reset (loss of the BTS) close down all remaining
RTP Proxy sockets. In case of a lchan_free shout if the rtp
proxy is still open. I would prefer if the proxy code sits inside
the gsm subscriber connection.

gsm_data_shared.h includes e1_input.h of libosmo-abis, add the
LIBOSMOABIS_CFLAGS to Makefile.am, remove AM_LDFLAGS at the same
time as we only build .a archives.
|
|
Increase the version number and send the sizeof of the gsm_mncc
and the gsm_data_frame structure. Include the offsets of some
members as well to maybe identify ABI problems.
The reason we go through this is that we want to benefit from
the native ABI and don't want to force packed structs.
|
|
In case of a memory allocation failure in rsl_rx_chan_rqd we would
have left the channel in the LCHAN_S_ACT_REQ state. Move the state
change below the allocation.
|
|
Use the name of GSM 08.58 for the release mode.
|
|
|
|
In case a BTS does not send the RF Channel Release ACK and we are
closing the channel because of an error two timers are running to
set the state back to none.
Make lchan_deact_tmr_cb and rsl_rx_rf_chan_rel_ack behave the same
in regard to changing the state of the lchan. For the other direction
we are save, the error path will set the state to NONE and the timeout
will call lchan_free to set the channel type back to NONE, only then
the lchan may be allocated again.
The channel release procedure requires some more tweaking, some part
was started in the zecke/28c3 branch and needs to be tested/integrated
with the goal of having one common release path.
|
|
In case of a failed channel we still want the channel to not be
re-allocated right away but keep it closed/unused for (T3109 + T311).
rsl_rx_rf_chan_rel_ack has a check to not set the channel to S_NONE in
case the channel is in the error state. Add the camp Harald added a timer
to set the channel back to the none state in case the RF Channel Release
is not acked.
This reverts commit fc462dd59ee4772f06c9f2477b36b3f166a8e74b.

show lchan should be capable of showing all allocated lchans,
all of a given bts, a given trx, a given ts. This feature was
broken when I added the ability to show a more simple summary.
Restore the initial behavior by splitting out the for loops
for the bts/trx/ts and check if we have parsed all parameters
and then call and return the subroutine.

Match IMSI and destination address against a set of entries, if it
is matching the header will be modified and no sender report will be
requested. Change the test case to request the sender report and then
verify that this bit is reset to 0.

SMS went from SAPI=3 to SAPI=0 and nobody notices on the NAT->MSC direction.
