fix time-delta calculations for measurement reports The previous implementation unconditionally subtracted nanosecond values from different time measurements, causing overflow if the current measurement was taken in less of a fraction of a second than the past measurement. Use timespecsub() instead, which accounts for nanoseconds correctly. Also, fix calculations of KBit/s throughtput. It was not being calculated correctly, since it was actually accounting for one KB per 128th-part-of-a-second. Change-Id: I7d22e7b5902c230efeae66eb20c17026a4037887 Related: OS#3225
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.
