Use always RFN when handling RACH indications The previous code was really confusing, passing full FNs as RFNs under certain external conditions, and then assuming the RFN input of rfn_to_fn() function could actually be a FN. As a result, we had a lot of code behaving slightly different depending on whether the incomding FN from pcuif was filled in by a BSC or a BTS. Avoid this b ehavior differentiation and always assume the most restricted one, aka RFN. Change-Id: Ib3b5702168195b595711cd0ff32c211b9aba429d
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.
