	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.

2017-07-12	Use libvlr in libmsc (large refactoring)	Harald Welte	1	-1/+3
	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.

2017-07-12	move openbsc/* to repos root	Neels Hofmeyr	1	-0/+112
	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. Change-Id: I9c6f2a448d9cb1cc088cf1cf6918b69d7e69b4e7
2009-06-10	move openbsc into its own subdirectory	Harald Welte	1	-1/+0

2008-12-31	Move the db_test.c to a specific test directory	Holger Freyther	1	-1/+1

2008-12-28	Add stubs to test gsm0408 functionality including LAI	Holger Freyther	1	-1/+1

2008-12-28	Add SMS (GSM 04.11) testing program	Daniel Willmann	1	-1/+1

2008-12-27	Add code to parse a debug category string	Holger Freyther	1	-1/+1
	Use strdup to be able to use strtok on the category string and add a test case. Also safe some more information to be able to use color in the print statement.
2008-12-27	Introduce a simple timer API....	Holger Freyther	1	-0/+1
	One can use add_timer or schedule_timer to add a timer. After the timeout time has been reached the callback will be called. One can call add_time/schedule_timer and del_timer from within the callback.
