Create new specific file for BSSGP code

Right now there's no much code there since the related code is totally
entangled with the LLC one.
This will eventually change in the future when we switch to use
libosmo-gprs.
Hence, this commit is a preparation to have already some place to put
new BSSGP specific code in the future.

osmo-sgssn - Osmocom SGSN Implementation

This repository contains a C-language implementation of a GSM Serving GPRS Support Node (SGSN) for 2G (GSM) and 3G (UMTS). It is part of the Osmocom Open Source Mobile Communications project.

OsmoSGSN exposes

  • Gb towards PCUs (e.g. OsmoPCU): Various GbIP flavors + Gb/FR/E1
  • 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

OsmoSGSN implements

  • GPRS mobility management
  • GPRS session management

History

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.
