osmo-msc - Osmocom MSC Implementation
|
|
=====================================
|
|
|
|
This repository contains a C-language implementation of a GSM Mobile Switching
|
|
Centre (MSC) for 2G (GSM) and 3G (UMTS). It is part of the
|
|
[Osmocom](https://osmocom.org/) Open Source Mobile Communications
|
|
project.
|
|
|
|
OsmoMSC exposes
|
|
* A over IP towards BSCs (e.g. OsmoBSC): 3GPP AoIP or SCCPlite
|
|
* IuCS over IP towards RNCs / HNBGW (e.g. osmo-hnbgw)
|
|
* The Osmocom typical telnet VTY and CTRL interfaces.
|
|
* The Osmocom typical statsd exporter.
|
|
|
|
OsmoMSC implements
|
|
* mobility management
|
|
* call control (either via built-in MNCC handler or external osmo-sip-connector)
|
|
* USSD (exposed via GSUP)
|
|
* SMS (either via built-in SMSC or external via GSUP)

History
|
|
-------
|
|
|
|
OsmoMSC originated from the OsmoNITB project, which started as a minimalistic
|
|
all-in-one implementation of the GSM Network. In 2017, OsmoNITB 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.
|
|
|
|
OsmoMSC was one of the parts split off from the old openbsc.git.
