osmo-bsc - Osmocom BSC Implementation
|
||
|
=====================================
|
||
|
|
||
|
This repository contains a C-language implementation of a GSM Base Station
|
||
|
Controller (BSC). IT is part of the
|
||
|
[Osmocom](https://osmocom.org/) Open Source Mobile Communications
|
||
|
project.
|
||
|
|
||
|
OsmoBSC exposes
|
||
|
* A over IP towards an MSC (e.g. OsmoMSC): 3GPP AoIP or SCCPlite
|
||
|
* Abis interfaces towards various kinds of BTS (osmo-bts, sysmobts, nanoBTS, Siemens, Nokia, Ericsson)
|
||
|
* The Osmocom typical telnet VTY and CTRL interfaces.
|
||
|
* The Osmocom typical statsd exporter.
|
||
|
* Cell Broadcast Service Protocol (CBSP) towards a CBC (Cell Broadcast Centre, such as osmo-cbc).
|
||
|
* Lb interface towards a SMLC (Serving Mobile Location Centre, such as osmo-smlc).

History
|
||
|
-------
|
||
|
|
||
|
OsmoBSC originated from the OpenBSC project, which started as a minimalistic
|
||
|
all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached
|
||
|
maturity and diversity (including M3UA SIGTRAN and 3G support in the form of
|
||
|
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 was one of the parts split off from the old openbsc.git. Before, it
|
||
|
worked as a standalone osmo-bsc binary as well as a combination of libbsc and
|
||
|
libmsc, i.e. the old OsmoNITB. Since the standalone OsmoMSC with a true A
|
||
|
interface (and IuCS for 3G support) is available, OsmoBSC exists only as a
|
||
|
separate standalone entity.
|
||
|
|
||
|
OsmoBSC-NAT is a specialized solution to navigating RTP streams through a NAT.
