gprs_rlc_ts_alloc: ensure no rolling slots are allocated When allocating multiple slots for a UE the following example is not allowed 'UU----UU' for a UE class 12. The time slot number can not roll over 7 and move to 0. 44.060 or 45.002 only specifies contigous however it was unclear it this is an allowed pattern. Only the example 45.002 B.3 in release 12 cleared this up. It gives an example for a multi slot class 5 UE which has 7 possible configuration this means the rolled over is not allowed. Multislot class type 2 UE doesn't have this limitation. Further if a UE supports 8 time slots this is not a limitation because the window size (45.002 B.1) can include all time slots.

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.
