= Installing a GSM network from scratch =
This document describes how to install, configure and run BTS transceiver, OsmoBTS, OpenBSC and LCR.
In order to use this quick howto, you must have basic knowledge about GIT and be familiar with compiling packages from source.
== Prerequisite ==
=== opencore-amr ===
This package installs GSM adaptive multirate codecs
It can downloaded at [http://sourceforge.net/projects/opencore-amr/files/opencore-amr/]
{{{
tar xvzf opencore-amr-x.x.x.tar.gz
cd opencore-amr-x.x.x
./configure
make
make install
ldconfig
cd ..
}}}
=== Sip-Sofia ===
This package installs the open source SIP stack of Nokia Research Center.
It can downloaded at [http://sourceforge.net/projects/sofia-sip/files/sofia-sip/].
{{{
tar xvzf sofia-sip-x.xx.xx.tar.gz
cd sofia-sip-x.xx.xx
./configure
make
make install
ldconfig
cd ..
}}}
=== oRTP ===
This package installs the open source RTP protocol required for libosmo-abis.
It can downloaded at [http://download.savannah.gnu.org/releases/linphone/ortp/sources/].
{{{
tar xvzf ortp-x.xx.x.tar.gz
cd ortp-x.xx.x
./configure
make
make install
ldconfig
cd ..
}}}
=== others ===
sqlite3 and libdbi should be available from your distribution.
== Installing ==
=== Linux-Call-Router (LCR) ===
This package installs the open source PBX software to bridge ISDN (DSS1) / SIP / GSM (MNCC protocol)
The latest version can downloaded via git:
{{{
git clone git://git.misdn.eu/lcr.git/
}}}
{{{
cd lcr
autoreconf -i
./configure --with-sip --with-gsm-bs --with-gsm-ms --enable-gsm-hr
}}}
Sometimes it is necessary to point to different .../lib/pkgconfig/ path: PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/ ./configure .....)
result should include:
configure: Compiled with GSM network side support
configure: Compiled with GSM mobile side support
configure: Compiled with GSM half rate codec support
configure: Compiled with GSM AMR codec support
configure: Compiled with SIP support
make
make install
ldconfig
cd ..
libosmocore: (core utility library for various osmocom projects)
load via git: git clone git://git.osmocom.org/libosmocore.git
cd libosmocore
git checkout -b
autoreconf -i
./configure
make
make install
ldconfig
cd ..
libosmo-abis: (library for openbsc)
load via git: git clone git://git.osmocom.org/libosmo-abis.git
cd libosmo-abis
autoreconf -i
./configure
(sometimes it is necessary to point to different .../lib/pkgconfig/ path: PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/ ./configure .....)
make
make install
ldconfig
cd ..
openbsc: (GSM base station controller)
load via git: git clone git://git.osmocom.org/openbsc.git
cd openbsc/openbsc/
change repository: git checkout -b jolly/testing origin/jolly/testing
autoreconf -i
./configure
(sometimes it is necessary to point to different .../lib/pkgconfig/ path: PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/ ./configure .....)
make
make install
cd ../..
osmo-bts: (BTS software)
load via git: git clone git://git.osmocom.org/osmo-bts.git
cd osmo-bts
change repository: git checkout -b jolly/trx origin/jolly/trx
autoreconf -i
./configure --enable-trx
(sometimes it is necessary to point to different .../lib/pkgconfig/ path: PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/ ./configure .....)
make
make install
cd ..
