Introduce libsmpputil

As part of preparation for libosmo-netif migration let's move common SMPP code
into separate build-time library and use it for both smpp_mirror and OsmoMSC
renaming the files if necessary.

While at it we also fix id/password legth limits in smpp_mirror and drop unused
fields from ESME struct.

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 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.
