Avoid moving DL-TBF from old_msg to new_ms during ms_merge The DL-TBF assigned to another MS object may have a totally different set of reserved resources (TS set, TRX, etc.), so one cannot simply move those to the new MS. To start with, if the 2 MS are on different TRX it is clear that one of them will not be really in operation. That's most probably the DL-TBF being in ASSIGN state on CCCH waiting for PCUIF_CNF and later X2002 to trigger to start sending DL blocks, but without confirmation whether the MS is really there. Since the other new MS object probably has a UL-TBF, that's the one probably operative, and hence a new DL-TBF can be created at that same time and assigned through UL-TBF's PACCH. Unit test test_ms_merge_dl_tbf_different_trx showcases the above scenario.

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.
