T_defs_pcu: Set default val for X2000 to 0 ms That timer is really only useful to free the tbf asynchronously after generating the Pkt Access Reject message, since we have nothing to do with it after the message is sent, and the dummt TBF doesn't really hold any reserved resource such as USF or TFI. The timer is useful to still do the freeing asyncrhonously, since the scheduler is interacting with the TBF during the code path, but there's no real need to keep the object alive for 2 ms afterwards. Having a default value of 0 ms is enough, since it fullfills the requirement of freeing asnchronously. The value of 2 ms was set initially when the reject support was added here (e9a138e11111f509f988807bbdc5ca8cce2b3d3d), with no specific explanation on the 2 ms value. It was just probably picked as a convinience one, but 0 is actually more convinient. Change-Id: I60e34e643f5c9d9afaf85530c54ab3232dc8f0be
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.
