Philipp Maier bc3c004c49 WIP: Integrate AoIP into OsmoBSC
Change-Id: I5ae4e05ee7c57cad341ea5e86af37c1f6b0ffa77

Neels Hofmeyr ef2d29f2a1 Implement IuCS (large refactoring and addition)
osmo-nitb becomes osmo-msc
add DIUCS debug log constant
add iucs.[hc]
add msc vty, remove nitb vty
add libiudummy, to avoid linking Iu deps in tests
Use new msc_tx_dtap() instead of gsm0808_submit_dtap()
libmgcp: add mgcpgw client API
bridge calls via mgcpgw

mgcp: hack RAB success from nano3G: patch first RTP payload
The ip.access nano3G needs the first RTP payload's first two bytes to read hex
'e400', or it will reject the RAB assignment. Add flag
patched_first_rtp_payload to mgcp_rtp_state to detect the first RTP payload on
a stream, and overwrite its first bytes with e400. This should probably be
configurable, but seems to not harm other femto cells (as long as we patch only
the first RTP payload in each stream). Only do this when sending to the BTS
side.

Harald Welte 80e6ece792 Use libvlr in libmsc (large refactoring)
Original libvlr code is by Harald Welte <laforge@gnumonks.org>,
polished and tweaked by Neels Hofmeyr <nhofmeyr@sysmocom.de>.

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.

SMS:

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.

Neels Hofmeyr 0b5cf1d1d4 move openbsc/* to repos root
This is the first step in creating this repository from the legacy openbsc.git.
Like all other Osmocom repositories, keep the autoconf and automake files in
the repository root. openbsc.git has been the sole exception, which ends now.

Harald Welte d3ff51dfe3 don't prefix every line with timestamp, this saves some screen real estate 2009-06-09 20:21:57 +00:00
Harald Welte c125a680ef A new debug flag is introduced: "DMNCC". MNCC is the Mobile Network Call
Control. This is required for later patches, that extract the call
control from gsm_04_08.c. (Andreas Eversberg)

Harald Welte edb3778542 * Add support for multiple ip.access nanoBTS at one BSC
* keep track of site_id/bts_id in struct gsm_bts
 * dynamically match incoming OML/RSL over TCP connections by BTS Unit ID
 * introduce new debug category DINP (separate from DMI for hexdumps)
 * remove ia_config() as it is no longer needed
 * 
* ensure that signalling links / E1 line information is correctly printed
* when bootstrapping RSL or OML, tell us for which BTS it is being doen
* separate bootstrap_bts() out from bootstrap_network()
* statically configure two ip.access BTS, one with unit id's 1800/0/0 and 1801/0/0

Holger Freyther ca362a6028 Make gcc happy and remove a couple of warnings
Remove the callbacks from gsm_network for now. A set of different
callbacks will be back. E.g. when the paging is completed, when the
Q.931 like call handling is there...

Remove var's or move them into #if 0, remove unused stuff that looks
like we do not need it anytime soon or #if 0 them, move stuff around.

known trick to get compile time assertions.

in the print statement.
