Error trying to obtain FN from RFN if curr_fn not known This may happen if a RACH.ind is received before any DATA.ind has been received. With usual osmo-bts-trx or osmo-bts-sysmo, this shouldn't happen nowadays, but it is still a problem with osmo-bts-virtual, where lower layers don't submit NOPE.ind in the absence of data, and hence it won't sent DATA.ind to osmo-pcu all the time. This change helps in showcasing confusing scenarios where the RFN generated in the Imm Ass was wrong. Change-Id: I29b7ba828fe890f90e35686bbb04d4abfe56b955
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
The official homepage of the project is https://osmocom.org/projects/osmopcu/wiki/OsmoPCU
You can clone from the official osmo-pcu.git repository using
git clone https://gitea.osmocom.org/cellular-infrastructure/osmo-pcu
There is a web interface at https://gitea.osmocom.org/cellular-infrastructure/osmo-pcu
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.
