tbf_ul_ass_fsm.c: Fix missing state transition in FSM description As seen operating PCU after BTS restart, lots of following message sequences due to FSM kept in same state (hence scheduler retyring every time): """ DTBF tbf_ul_ass_fsm.c:306 UL_ASS_TBF(DL-TFI_0){SEND_ASS}: Received Event CREATE_RLCMAC_MSG DTBF tbf_ul_ass_fsm.c:95 TBF(TFI=0 TLLI=0xf80bd801 DIR=DL STATE=RELEASING EGPRS) We have a schedule for uplink assignment, but there is no uplink TBF DTBF tbf_ul_ass_fsm.c:97 UL_ASS_TBF(DL-TFI_0){SEND_ASS}: transition to state NONE not permitted!

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.
