Philipp Maier 72b8c38287 doc: do not use random ip-address for MGW
The example configs suggest to use a random ip-address as MGW address.
Lets use a loopback address here. This will suit the usual case where
MGW and MSC run together on the same machine.

Philipp Maier f896c690be doc: update mgw settings in example config file
This example configuration files lack port settings for the mgcp
client. Lets explicitly assign a port for the MGW and a local port.
For the local port lets use the IETF port number + 1. The reason
for this is that the default config for osmo-bsc already uses the
IETF port and in osmo-bsc and osmo-msc run on the same machine in
many setups.

Harald Welte 098aa71e83 remove unused "auth policy" VTY command
This is yet another unsused bit from the OsmoNITB legacy.

Harald Welte 27b40c601c remove unused VTY command "location updating reject cause"
OsmoMSC is using whatever reject cause is apropriate in the given
situation.  This user-configurable reject cause only had relevance
in OsmoNITB, and hence it is an unused parameter that can be removed
in OsmoMSC.

Neels Hofmeyr 48ba1be752 examples: apply mgcp_client vty rename from 'mgcpgw' to 'mgw'
osmo-mgw.git is changing the mgcp_client_vty API to use 'mgw' instead of
'mgcpgw'. Fix example configs after that patch is merged.

Neels Hofmeyr ca4875f133 fix vty tests: long timeout due to unreachable STP address
The doc/examples/osmo-msc SCCP config examples with as asp ip-remote
cause >5 minutes timeout for each VTY config test being run before the VTY
becomes available. This hugely elongates the config tests, we didn't spot it
before because it does succeed after that timeout. Rather use link-local
addresses in order to immediately note the lack of connection and carry on with
the VTY config tests.

Neels Hofmeyr 47cd0d2687 drop files unrelated to osmo-msc
These either remain from openbsc.git or slipped in while applying recent
patches from openbsc.git and do not belong in osmo-msc.

Empty out contrib: remove things that are either obviously unrelated to
osmo-msc, or seem old and/or esoteric.

Neels Hofmeyr 6d82bec2c8 MSC,SGSN: use OSMO_GSUP_PORT == 4222 instead of 2222
In SGSN, actually place the port in the SGSN config by default, so that the
gsup port may now be omitted in the VTY config (the IP address suffices).

Adjust the osmo-sgsn.cfg example.

Philipp Maier fbf6610dc1 Implement AoIP, port to M3UA SIGTRAN (large addition and refactoring)
This was originally a long series of commits converging to the final result
seen in this patch. It does not make much sense to review the smaller steps'
trial and error, we need to review this entire change as a whole.

Implement AoIP in osmo-msc and osmo-bsc.

Change over to the new libosmo-sigtran API with support for proper
SCCP/M3UA/SCTP stacking, as mandated by 3GPP specifications for the IuCS and
IuPS interfaces.

From here on, a separate osmo-stp process is required for SCCP routing between
OsmoBSC / OsmoHNBGW <-> OsmoMSC / OsmoSGSN build from libosmo-sccp and osmo-iuh master branches now for new

Harald Welte 5d1fa89819 GSM timers: User reasonable defaults; don't save if equal default
A number of the GSM timers (including T3109) had no reasonable
default values if not specified in the VTY / config file.  Together
with unconditional writing to the config file, this created
config files with a persistent setting for important timers as '0'.

To make things worse, many of our example cofig files suffered from the
same problem.

Let's avoid this from happening by
* having reasonable defaults if nothing specified in the config file
* conditionally savingg timers only if they differ from default
* reject any timer values that state zero during start-up (see previous

Daniel Willmann 8dc8ea435f examples/sgsn: Use osmo-hlr with auth-policy remote by default
For the vty tests, add osmo-sgsn-accept-all.cfg (that does not need an HLR) and
use in, otherwise the 'show sgsn' command will reply that it
could not connect to the HLR, failing the vty test which expects empty.

Daniel Willmann 2be19428f7 examples: Change IP address of config files
This helps in providing 3G software packages for the sysmoNITB hardware, which
uses for SGSN and for GGSN.

However, in order to not break the python tests, the osmo-sgsn.cfg example
still uses as local address.

Change the GGSN address to, because SGSN and GGSN cannot co-exist on
the same address (the GTP port number is fixed by spec: no IE to communicate a
differing port, so it has to be the standard GTP port for both).

Harald Welte 2483f1b050 Use libvlr in libmsc (large refactoring)
Original libvlr code is by Harald Welte <>,
polished and tweaked by Neels Hofmeyr <>.

This is a long series of trial-and-error development collapsed in one patch.
This may be split in smaller commits if reviewers prefer that. If we can keep
it as one, we have saved ourselves the additional separation work.


The SQL based lookup of SMS for attached subscribers no longer works since the
SQL database no longer has the subscriber data. Replace with a round-robin on
the SMS recipient MSISDNs paired with a VLR subscriber RAM lookup whether the
subscriber is currently attached.

If there are many SMS for not-attached subscribers in the SMS database, this
will become inefficient: a DB hit returns a pending SMS, the RAM lookup will
reveal that the subscriber is not attached, after which the DB is hit for the
next SMS. It would become more efficient e.g. by having an MSISDN based hash
list for the VLR subscribers and by marking non-attached SMS recipients in the
SMS database so that they can be excluded with the SQL query already.

There is a sanity limit to do at most 100 db hits per attempt to find a pending
SMS. So if there are more than 100 stored SMS waiting for their recipients to
actually attach to the MSC, it may take more than one SMS queue trigger to
deliver SMS for subscribers that are actually attached.

This is not very beautiful, but is merely intended to carry us over to a time
when we have a proper separate SMSC entity.

Introduce gsm_subscriber_connection ref-counting in libmsc.

Remove/Disable VTY and CTRL commands to create subscribers, which is now a task
of the OsmoHLR. Adjust the python tests accordingly.

Remove VTY cmd subscriber-keep-in-ram.

Use OSMO_GSUP_PORT = 4222 instead of 2222. See

So far use the LAC from conn->bts, will be replaced by conn->lac in

Neels Hofmeyr 625e05a6b2 fix make distcheck with python tests
- bscs.config needed by the vty tests was not picked up as a dist file, because
  its suffix is not 'cfg'. Rename to *.cfg. Apply this rename in and osmo-bsc_nat.cfg.
- Remove restart counters after external tests, otherwise distcheck complains
  about uncleaned files.
- Add contrib/ to EXTRA_DIST, hence add a to contrib/.
  Otherwise the python tests cannot find that dependency.
