Receive the mnc_3_digits flag from the PCU interface. Bump the PCU interface to 9. This is one part of the three identical pcuif_proto.h patches: - I49cd762c3c9d7ee6a82451bdf3ffa2a060767947 (osmo-bts) - I787fed84a7b613158a5618dd5cffafe4e4927234 (osmo-pcu) - I78f30aef7aa224b2e9db54c3a844d8f520b3aee0 (osmo-bsc) Add 3-digit flags and use the new RAI and LAI API from libosmocore throughout the code base to be able to handle an MNC < 100 that has three digits (leading zeros). Depends: Id2240f7f518494c9df6c8bda52c0d5092f90f221 (libosmocore), Ib7176b1d65a03b76f41f94bc9d3293a8a07d24c6 (libosmocore) Change-Id: I787fed84a7b613158a5618dd5cffafe4e4927234 |

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
Homepage
The official homepage of the project is https://osmocom.org/projects/osmopcu/wiki/OsmoPCU
GIT Repository
You can clone from the official osmo-pcu.git repository using
git clone git://git.osmocom.org/osmo-pcu.git
There is a cgit interface at http://git.osmocom.org/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.
