About OsmoSGSN |
||||
============== |
||||
|
||||
OsmoSGSN originated from the OpenBSC project, as a separate program within |
||||
openbsc.git. In 2017, OpenBSC was split in separate repositories, and hence |
||||
OsmoSGSN was given its own separate git repository. |
||||
|
||||
OsmoSGSN exposes |
||||
- GSUP towards OsmoHLR (or a MAP proxy); |
||||
- GTP towards a GGSN (e.g. OsmoGGSN); |
||||
- Gb towards a BSS (e.g. OsmoPCU); |
||||
- IuPS towards an RNC or HNB-GW (e.g. OsmoHNBGW) for 3G data; |
||||
- The Osmocom typical telnet VTY and CTRL interfaces. |

* GTP towards a GGSN (e.g. OsmoGGSN); |
||||
* IuPS over IP towards RNCs / HNBGW (e.g. osmo-hnbgw) |
||||
* The Osmocom typical telnet VTY and CTRL interfaces. |
||||
* The Osmocom typical statsd exporter. |
||||
* GSUP (custom MAP-like protocol) towards osmo-hlr |
