About OsmoMSC |
|
|
|
|
============= |
|
|
|
|
|
|
|
|
|
OsmoMSC 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. |
|
|
|
|
OsmoMSC is an implementation of the 3GPP MSC (Mobile Switching Centre) |
|
|
|
|
network element. It implements the following core functionality within |
|
|
|
|
the 2G (GSM) and 3G (UMTS) networks: |

|
OsmoMSC was one of the parts split off from the old openbsc.git. Before, it was |
|
|
|
|
the libmsc part of the old OsmoNITB. Since a true A interface and IuCS for 3G |
|
|
|
|
support is available, OsmoMSC exists only as a separate standalone entity. |
