Avoid using N3105 in UL TBFs This counter is only used in DL TBFs as per TS 44.060. section 13.4 "N3105": "When the network after sending a RRBP field in the _downlink RLC data block_ ..." (DL data blocks are only sent in DL TBFs). section 8.1.2.1: "If N3105 = N3105max, the network shall release the downlink TBF internally and start timer T3195 for that TBF. When T3195 expires, the network may reuse the TFI" Change-Id: I4d4f4d4d3e6e0539ea8ec2395bed00d059b84e04
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.
