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.
OpenBSC started as a minimalistic all-in-one implementation of the GSM Network,
with particular emphasis on the functionality typically provided by the BSC,
MSC, HLR, VLR and SMSC. Today it is a growing suite of libraries and programs,
implementing protocol stacks and functional elements, including
Its currently supported interfaces towards the BTS are:
* OsmoBSC - a pure GSM BSC, speaking Abis/IP to the BTS and A/IP to the MSC
* OsmoBSC-MGCP - MGCP helper to the OsmoBSC software
* OsmoNITB - a BTS+MSC+VLR+HLR+SMSC "Network in the box".
* OsmoSGSN - a GPRS SGSN with Gb interface over IP towards the PCU
* Osmo-GbProxy - a Proxy to aggregate many Gb links as one Gb link to the SGSN
* OsmoBSCNAT - a gateay aggregating many A links as one A link to the MSC
* OsmoGTPHUB - a hub aggregating many GTP links (between SGSN and GGSN)
* ipaccess-utils - some tools to discover + configure ip.access nanoBTS
* bs11_config - a tool to configure the Siemens BS-11 microBTS
The 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!
through E1 to OpenBSC. So far, we have made it work with the Siemens BS-11,
various Ericsson RBS2xxx BTS models and the Nokia MetroSite.
* A-bis over IP as used by the ip.access nanoBTS product family
* A-bis over IP as used by the ip.access nanoBTS product family as well as
the Open Source OsmoBTS software (by the same authors as OpenBSC). OsmoBTS
in turn supports various transceiver hardware, including the sysmoBTS
product family, as well as SDR transceivers supported by OsmoTRX, such as
the UmTRX or USRP boardss.

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
