osmo-pcu - Osmocom Packet Control Unit

This repository contains a C/C++-language implementation of a GPRS
Packet Control Unit, as specified by ETSI/3GPP. It is part of the
Osmocom Open Source Mobile Communications
project.

The Packet Control Unit is terminating the Layer 2 (RLC/MAC) of the GPRS
radio interface and adapting it to the Gb Interface (BSSGP+NS Protocol)
towards the SGSN.

The PCU interfaces with the physical layer of the radio interface.
OsmoPCU is typically used co-located with the BTS, specifically
OsmoBTS.
For legacy BTSs that run proprietary sotware without an interface to
OsmoPCU, you may also co-locate it with the BSC, specifically
OsmoBSC

GIT Repository

You can clone from the official osmo-pcu.git repository using

  1. git clone https://gitea.osmocom.org/cellular-infrastructure/osmo-pcu

There is a web interface at https://gitea.osmocom.org/cellular-infrastructure/osmo-pcu

Documentation

We provide a
user manual
as well as a
vty reference manual

Please note that a lot of the PCU configuration actually happens inside
the BSC, which passes this configuration via A-bis OML to the BTS, which
then in turn passes it via the PCU socket into OsmoPCU.
