WIP: Support ANR procedures on MS with active TBF TODO: * General clean up * Find out and fix why MS not resetting Neighbour List to BA(GPRS) when empty NC_Frequency_List is sent in Packet Measurement Order. * Fix MS most of the time not sending Neighbour report for cells not present in SI2, probably due to waiting not enough time (increasing NC_REPORTING_PERIOD_T may help, but then problem in previous point above may show up more). Also maybe waiting for several reports before continuing may also help. * Configurable/dynamic chunk list size currently hardcoded to 5. Improvements/optimizations: * Use FREQUENCY_DIFF in Add_Frequency for NC_Frequency_List to make it smaller and hence require less PAcketMeasurementOrder messages. * Support Enchanced Packet Report message (need to signal support for it too).

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.
