Holger Hans Peter Freyther 7b7eef62c1 nat: Change MGCP DLCX handling and send dummy MDCX to the BTS. When setting a new MSC timeslot to a SCCP connection check if any of the existing connections have this timeslot, if so we will send a DLCX down the stream to make sure it is closed there, when we will CRCX this new timeslot we will happily reallocate it. When the SCCP connection goes away, or we get a DLCX from the network, or the BSC is gone we will send a DLCX message down the stream as well. When we receive a CRCX from the network we will forward the CRCX as usual and send a dummy MDCX after it. For the DLCX and the dummy MDCX we send a custom MGCP message that will not provoke an answer. Even if the downstream MGCP GW will answer we will ignore it due the dummy transaction id that is not used anywhere else. This change should make sure that we close the dowstream endpoint all the time, even when the DLCX arrives after the SCCP connection is torndown.		2010-06-15 20:24:16 +08:00

About OpenBSC
=============

OpenBSC is a minimalistic implementation of the GSM Network, with
particular emphasis on the functionality typically provided by the BSC,
MSC, HLR, VLR and SMSC.

Its currently supported interfaces towards the BTS are:

 * Classic A-bis over E1 using a mISDN based E1 interface. In other
   words, you can connect existing GSM Base Transceiver Station (BTS)
   through E1 to OpenBSC.  So far, we have only tested the Siemens BS-11
   Test reports with other BTS are much appreciated!

 * A-bis over IP as used by the ip.access nanoBTS product family

You can find the project documentation at http://openbsc.gnumonks.org/

This project is still in its early days, and there are lots of areas where it
doesn't behave as per GSM spec.

libosmocore
===========

Please note that as of March 2010, OpenBSC has a dependency to a library
called "libosmocore".  You can obtain that library from

	git://git.osmocom.org/libosmocore.git
