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.

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

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

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.

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.

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.

The osmo-nitb application sometimes crashes because the BSC API
is doing an assignment underneath which is not handled by the code,
add dumy handlers to not crash, the right thing to do is to change
MNCC to have an assignment that can succeed/fail.
The keyword to look for is MNCC_LCHAN_MODIFY and mncc_sock should
wait for an ack/nack but right now the call just continues.

The UTC offset from the operating system will be used by default to
calculate the NITZ in MM INFO. However, a "timezone" vty command is
added at the BTS level, allowing BTS-specific overrides, e.g. in case
BTSs are distributed accross multiple timezones.

The typo was fixed upstream

Also make sure to specify seconds in the 'seconds' field. Doing
otherwise is an abuse that non longer works with the new timer infra.

do_reset was not initialized anywhere anymore, so the reset was never
triggered. It's now fixed and we add an option to skip it in the
config so that when in production, you can restart without config
changes quickly.

The NVC never goes to OFF LINE but only to DEPENDENCY (because of

When the BTS reboots it might not want to accept our BTS Attr,
do not leave the bsc_msc_ip/bsc_nitb but simply drop the BTS
connection.

The libosmo-abis merge broke Ericsson RBS support, as it didn't get the
part right where the per-TRX OML sign_link is determined while
transmitting OM2000 messages.
As a result of this fix, we can remove the 'to_trx_oml' parameter to
_abis_nm_sendmsg(), which is a nice cleanup.

When gsm48_send_rr_ass_cmd() is being called to send the ASSIGNMENT
COMMAND, we need to use the propwer lchan->ms_power setting, not
some fixed magic "0x3" number.
Without this patch, every MS would transmit at a very high output power
fullowing an assignment command - more than what was set in the config
file with "ms max power"

In case of a nack the secondary_lchan will be NULLed but then the T10
timeout will attempt to release the channel and we will try to release
a NULL pointer.
Daniel witnessed this crash at the camp and added the NULL check at:
28d9ccbca0cb522c90f551cf4bf243acab7a1944, it is also the proper fix
given the _NAK handling.
