Helps decode T&E log, GPEH, UETR & CTR files. Works on older linux os (like Knoppix5.1).
If someone has newer version please e-mail me dejo36@yahoo.com !

The UTRAN Field DECODER
=======================
Field decoder made by David Smith <david.smith@ericsson.com>.
Based on version of decoder.pl by Martin Andersson / Anders Forsman + more from vobs

This is strictly an Ericsson internal tool provided for informational purposes only!

For support with this version of decoder, and for the latest versions please use the moshell web page:

To decode P5 UETR/CTR/GPEH
==========================
Same as for P4 UETR/CTR, use either GPEH or UETR flag, e.g.

decoder.pl --uetr uetrfile.bin | decoder.pl --extern

or

decoder.pl --gpeh uetrfile.bin | decoder.pl --extern

Note that you have to pipe the output to "decoder.pl --extern" in order to decode the embedded signalling messages such as NBAP,RRC,etc.

To decode P4 UETR/CTR
==========================
decoder.pl --uetr uetrfile.bin | decoder.pl --extern

To decoder P4 GPEH
==================
decoder.pl --p4 --gpeh gpehfile.bin

To decode te log read or monitor output
=======================================
decoder.pl

e.g. from MoShell "lh mod5 te log read | decoder.pl"
or: monitor6054 <ipaddress> <lnh> | decoder.pl

To display one line per message (flow)
======================================
Pipe the output of decoder.pl into flow.pl.

Usage: flow.pl [-nodetail] [-multiline] [-colour] [-noheader] [-showrrcreq] [-meascont] [-event] [-string <string>] [file]

Example: lh mod5 te log read | decoder.pl | flow.pl -colour
monitor6054 <ipaddress> <port> | decoder.pl | flow.pl -colour

To decode/flow SS7 messages
===========================
Enable trace3 on Scc_xxxServer_proc (where xxx is one of: itu, ansi, ttc, china)
lh sccpmp te log read | decoder_ss7 | flow_ss7
or: monitor6054 <ipaddress> <port> | decoder_ss7 | flow_ss7

To use your uetrXplorer and other RF tools with a decoded UETR
==============================================================
uetr2uetrXplorer.awk decodedUETR.txt

To decode History Data Dump traces from DC devices.
===================================================
Pipe the T&E log of the DC devices to the historyDecoder.pl. The traces look like this when undecoded:
[2007-10-18 05:15:05.302] DedicatedChModelPT ../src/DcsIubDataHistoryD.cpp:281 ERROR:History dataDump(run historyDecoder.pl script to decode.): (156,-2,-1516)(156,178,1515)(-117,228,1495)(148,0,-1481)(148,0,-1481)(-113,228,1456)(144,0,-1441)(140,0,-1401)(136,0,-1361)(132,0,-1321)(128,0,-1281)(124,0,-1241)(120,0,-1201)(116,0,-1161)(112,0,-1121)(108,0,-1081)(104,0,-1041)(104,0,-1041)(-69,228,1017)(100,1,-1001)(100,0,-1001)(-65,228,978)(96,0,-961)(96,0,-961)(100,178,959)

To produce a signaling flow from an OSS GPEH decoded TAB file
=============================================================
GPEH_tab2flow.pl input_file.tab
or: gunzip -c input_file.tab.gz | GPEH_tab2flow.pl

===========
1) INTERNAL_MEAS_TRANSPORT_CHANNEL_BER

Transport Channel Bit Error Rate measurement on Dedicated Channel (DCH) after radio link combining. Every fifth TTI, the rate is recorded for the uplink TrCH BER.

2) INTERNAL_MEAS_TRANSPORT_CHANNEL_BLER

Transport Channel Block Error Rate on Uplink DCH. Measurement is sent every 10th second. Number of Transport Blocks and Number of Faulty Blocks.
