Revert "Use Timing Advance Index in UL assignments" This reverts commit 6298fbb7b2f3639fde994633e33ba54a64a6ef9b, I8b17be78a46c0bc17516b7c90f35aa4768010ae4. Commit I52ec9b07413daabba8cd5f1fba5c7b3af6a33389 / 896574e92bea09ed8d39688b6fdf504e84521746 was found (empirically) to be a regression, rendering GPRS service fatally unreliable. This reverted commit seems to follow after the regression and is reverted along with it. Related: OS#3013 Change-Id: I5e0fd8c9c3b89e519e7382e3d0bb24e0aeddeff6
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 git://git.osmocom.org/osmo-pcu.git
There is a cgit interface at http://git.osmocom.org/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.
