ms: Fix MS without PTMSI not freed immediatelly This check (tlli != 0) was added in 2015 in 6d86628e5b6d81afae4ca1f24201ee90bfab1c2a, with the rationale below: """ To avoid dangling entries without a TLLI there (which cannnot be retrieved anyway), the timer in the MS objects is not started after all TBF have been detached, so that they get deleted immediately in that case. """ The rationale makes sense, but through time the MS class was fixed to return GSM_RESERVED_TMSI (0xFFFFFFFF) when no TMSI was available. Hence, the check was wrong, and as a result, free() of MS containing GSM_RESERVED_TMSI would be delayed over time by release timer.

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.
