About OpenBSC About OsmoBSC
============= =============
OpenBSC started as a minimalistic all-in-one implementation of the GSM Network, OsmoBSC originated from the OpenBSC project, which started as a minimalistic
with particular emphasis on the functionality typically provided by the BSC, all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached
MSC, HLR, VLR and SMSC. Today it is a growing suite of libraries and programs, maturity and diversity (including M3UA SIGTRAN and 3G support in the form of
implementing protocol stacks and functional elements, including IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one
approach to fully independent separate programs as in typical GSM networks.
* OsmoBSC - a pure GSM BSC, speaking Abis/IP to the BTS and A/IP to the MSC OsmoBSC was one of the parts split off from the old openbsc.git. Before, it
* OsmoBSC-MGCP - MGCP helper to the OsmoBSC software worked as a standalone osmo-bsc binary as well as a combination of libbsc and
* OsmoNITB - a BSC+MSC+VLR+HLR+SMSC "Network in the box". libmsc, i.e. the old OsmoNITB. Since the standalone OsmoMSC with a true A
* OsmoMSC - a voice CN with A/IP and IuCS/IP towards the BSC and/or HNB-GW interface (and IuCS for 3G support) is available, OsmoBSC exists only as a
* OsmoSGSN - a GPRS SGSN with Gb/IP and IuPS/IP towards the PCU and/or HNB-GW separate standalone entity.
* Osmo-GbProxy - a Proxy to aggregate many Gb links as one Gb link to the SGSN
* OsmoBSCNAT - a gateway 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
Various interfaces towards the BTS are supported, among which are: OsmoBSC exposes
- A over IP towards an MSC (e.g. OsmoMSC);
- Abis interfaces towards various kinds of BTS;
- The Osmocom typical telnet VTY and CTRL interfaces.
* Classic A-bis over E1 using a mISDN based E1 interface. In other Find OsmoBSC issue tracker and wiki online at
words, you can connect existing GSM Base Transceiver Station (BTS) https://osmocom.org/projects/osmobsc
through E1 to OpenBSC. So far, we have made it work with the Siemens BS-11, https://osmocom.org/projects/osmobsc/wiki
various Ericsson RBS2xxx BTS models and the Nokia MetroSite.
* A-bis over IP as used by the ip.access nanoBTS product family as well as OsmoBSC-NAT is a specialized solution to navigating RTP streams through a NAT.
the Open Source OsmoBTS software (by the same authors as OpenBSC). OsmoBTS (Todo: describe in more detail)
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.
* IuCS and IuPS over IP towards an HNB-GW (see osmo-iuh) for UMTS (3G)
voice and data links.
