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.
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.
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 fc462dd59e.
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.
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.

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:
28d9ccbca0, it is also the proper fix
given the _NAK handling.
Remove the separation of half-rate and full-rate AMR. The used rate
can be found inside the AMR payload. The signalling of what kind of
traffic channel is used can be done with the GSM 08.08 Chosen
Channel IE in the Assignment Complete message.
This way I can use a fixed payload type in the MGCP GateWay but
have a mixed TCH/F and TCH/H config. E.g. use TCH/F FR3 for some
subscribers when connected to MSC A but use AMR5.9 on a TCH/F for
MSC B when all TCH/Hs are gone.
This is a big patch that ports openBSC over libosmo-abis.
Sorry, the changes that are included here are all dependent
of libosmo-abis, splitting them into smaller pieces would
leave the repository in some intermediate state, which is
not desired.
The main changes are:
- The directory libabis/ has been removed as it now lives in
libosmo-abis.
- new configuration file format for nanoBTS and HSL femto, we
need to define the virtual e1_line and attach it to the OML
link.
- all the existing BTS drivers (nanoBTS, hsl femto, Nokia site,
BS11 and rbs2000) now use the new libosmo-abis framework.
- use r232 input driver available in libosmo-abis for bs11_config.
- use ipa_msg_recv instead of old ipaccess_read_msg function.
- delete definition of gsm_e1_subslot and input_signal_data.
These structures now lives in libosmo-abis.
Most of this patch are deletions of libabis/ which has been
moved to libosmo-abis.
This patch also modifies openBSC to use all the new definitions
available in libosmocore and libosmo-abis. In order to do that,
we have replaced the following:
- DINP, DMI, DMIB and DMUX by their respective DL* correspondences.
- SS_GLOBAL by SS_L_GLOBAL
- SS_INPUT by SS_L_INPUT
- S_GLOBAL_SHUTDOWN by S_L_GLOBAL_SHUTDOWN
- SS_INPUT by SS_L_INPUT
- S_INP_* by S_L_INP_* sub-signals
- E1INP_NODE by L_E1INP_NODE vty node
This patch has been tested with:
- one nanoBTS
- the HSL femto with the examples available under libosmo-abis
- BS11 with both dahdi and misdn drivers.
This patch modifies openBSC code to use msg->dst which stores the
pointer to the signalling link structure instead of the pointer to
the transceiver structure.
This patch prepares the introduction of libosmo-abis.
It is possible that MNCC sends a MNCC_LCHAN_MODIFY and
wants a channel mode that is not possible on the current
lchan, in that case a new channel is assigned. We now crash
as the osmo-nitb is not having an assignment complete handler,
add a NULL check.
The Nokia metrosite BTS seem to keep the channels open indefinitely.
If osmo-nitb is restarted while one of the channel was still active
and tries to activate that channel again the bts would return a
CHANNEL ACTIVATE NACK with "Radio channel already activated". This
accumulated over the restarts so soon enough no more channels were
available.
This patch sends a release request to the bts so the channel
becomes available again.
The function lchan_alloc only considers lchans to be available if both
the type and state are NONE. So change show lchan to list all lchans
that are not considered available.
The timer callback will simply reset the lchan state to NONE in order
to prevent channels getting stuck in 'activation requested' or
'deactivation requested' states.
Running the entire bts_nokia_site.c through the 'Lindent' script
to match indent/coding style with remainder of project.
There are still lots of other cleanups pending, but this one is
a purely cosmetic one.
This fixes a bug introduced more than one year ago in commit
e38bd6caa34005816a9336f021fd17d328d5c901:
The RSL_IE_CHAN_IDENT is a TLV, but the GSM48_IE_CHANDESC_2 contained in
it, is a mere TV type IE with fixed length.
The problem specifically has caused problems on Nokia MetroSite BTS,
which apparently read the TSC out of this Layer3 IE.
Reset the BTS MO State on BTS bootstrap. This way we will always
test the BTS disconnect/reconnect case of the BTS.
Do not reset the administrative state of objects. The BSC might
have set these and wants to maintain them across disconnect/
reconnect. Right now this is true for the TRX state.
The daemons set up nanoBTS and HSL femto sockets by default, ie. the
three sockets to support these two drivers are open even if we have
no BTS of that kind.
This patch enables on-demand socket creation, ie. we only enable them
if we have one BTS at least that requires it.
I added two new attributes to the gsm_bts object, they are:
* the start() function includes the code that we need to run to start
the BTS. This new function contains the socket creation in the
particular case of nanoBTS and HSL femto.
* the started boolean, which is used to know if we have already
started the BTS, ie. we have already invoked start().
Note that, I have splitted the bts_model_*_init() function into two
functions, the _init() functions that register the BTS driver
and the _start() functions that start BTS driver on-demand.
While I was at it, I added several changes/cleanups to this patch:
* Group all bts_model_*_init() calls into one function bts_init(),
which is called in the initialization path of osmo-nitb and
osmo-bsc.
* Add openbsc/bss.h that contains the declaration of
bsc_bootstrap_network, bsc_shutdown_net and bts_init.
* Add missing e1inp_init() in osmo-bsc.
* Fix missing declaration of hsl_setup in openbsc/e1_input.h
The error message was missing in case of problems bootstrapping the BTS.
The E1 input driver initialization was displayed in the standard output,
now this error is reported via logs.
The code to create the struct gsm_bts is in libcommon right now
and we can not call paging_init from there. Right now it appears
to be the easiest of doing the init internally.
Be able to configure a list of destinations (duplicates allowed)
that will be tried in a round robin fashion. The change is in
the bsc_msc_connection to operate on a list. We achieve the
round robin nature with the same trick used in the paging code
to delete and append the current entry. The nat code was updated
to compile but one can only configure one destination.
