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

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

|
=========== |
|
|
|
|
|
|
|
|
|
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 |
