Description

Add tool to osmocom-bb that can decode SMS-CB and log data.

A good starting point is the work done by Alex Badea in 2010 and 2013:

  1. changes to libosmocore (even with unit tests)
    http://lists.osmocom.org/pipermail/baseband-devel/2013-January/003871.html
  2. changes to cell_log
    http://lists.osmocom.org/pipermail/baseband-devel/2013-January/003887.html
  3. changes to L1 (already merged in sylvain/testing)
    http://lists.osmocom.org/pipermail/baseband-devel/2013-January/003835.html
    http://lists.osmocom.org/pipermail/baseband-devel/2013-January/003836.html

There were reasons a that time to not to include these patches into master.

Time went by and now there's even initial support for SMSCB in OsmoBTS/OsmoBSC.

An interesting use-case for (at least for germans) could be the mapping of older BTS from VIAG-Interkom/O2 that still broadcast their locations in Gauss Krueger coordinates.
I've written a perl script that uses the logs from Alex Badeas patched cell_log to generate a KML file with the BTS's coordinates.
