bts: Add counter availablePDCHAllocatedTime We basically want to probe whether it's possible to allocate TBFs, or whether we know it will fail due to all main resources being already in use (TFI, USF). Having bts_all_pdch_allocated() return false doesn't mean though that an MS will be able to allocate a TBF for sure. That's because further restrictions are applied based on MS: whether it was already attached to a specific TRX, whether the ms_class allows for a certain multislot combination, etc. However, it should provide a general idea on whether for sure the PCU is unable to provide more allocations. More fine grained state about failures can still be followed by looking at tbf:alloc:failed:* rate counters.

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.
