nacc: Implement Pkt Cell Change Continue retransmission Use the fact that the MS must answer the RRBP of the Pkt Cell Change Continue with a CTRL ACK to find out whether the message was received successfuly or a retransmission is potentially required. 3GPP TS 44.060: """ When the mobile station receives the PACKET CELL CHANGE ORDER or the PACKET CELL CHANGE CONTINUE message the mobile station shall transmit a PACKET CONTROL ACKNOWLEDGMENT message in the specified uplink radio block if a valid RRBP field is received as part of the message; the mobile station may then switch to a new cell. """ Related: SYS#4909 Change-Id: I7cc28922e71699598da0ef6eb90136a47d3c002f
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.
