Persiapan

Set IP Adddress Statik

Edit 

vi /etc/network/interfaces

Isi dengan 

# Wired or wireless interfaces
auto eth0
# iface eth0 inet dhcp
iface eth1 inet dhcp

iface eth0 inet static  
	address 192.168.0.22
	netmask 255.255.255.0
	network 192.168.0.0
	gateway 192.168.0.222

Instalasi Aplikasi Pendukung

Instal aplikasi pendukung 

opkg update
opkg install libosip2-dev subversion sqlite3

Cek sqlite3 

sqlite3 --version

Harusnya keluar seperti 

3.6.23.1

Alternatif Download OpenBTS di PC / Laptop

Download di PC source code openbts bisa melalui 

cd /usr/local/src
apt-get install subversion
svn co http://wush.net/svn/range/software/public openbts-2.8.0

Kemudian di transfer ke E110 

scp -r openbts-2.8.0 root@<ip-address-E110>:

Compile OpenBTS

Cara yang lebih mudah untuk download menggunakan wget 

cd ~/src
svn co http://wush.net/svn/range/software/public openbts-2.8.0
vi ~/src/openbts-2.8.0/openbts/trunk/apps/OpenBTS.cpp

pastikan sleep > 5, misalnya 

sleep(8);

lanjutkan proses compile 

mkdir -p /etc/OpenBTS
touch /etc/OpenBTS/SubscriberRegistry.db
touch /etc/OpenBTS/ChannelTable.db
touch /etc/OpenBTS/Stats.db
touch /etc/OpenBTS/TMSITable.db
touch /etc/OpenBTS/Transaction.db
touch /etc/OpenBTS/command

cd ~/src/openbts-2.8.0/a53/trunk/
make
make install
cd ~/src/openbts-2.8.0/openbts/trunk
autoreconf -i
./configure --with-uhd --with-resamp CFLAGS="-march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp -O3" CXXFLAGS="-march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp -O3" 
make clean
rm -Rf ~/src/openbts-2.8.0/openbts/trunk/apps/transceiver
rm -Rf ~/src/openbts-2.8.0/openbts/trunk/Transceiver52M/transceiver
cd ~/src/openbts-2.8.0/openbts/trunk
make 
make install
cd ~/src/openbts-2.8.0/openbts/trunk/apps
ln -s ../Transceiver52M/transceiver .

mkdir /var/run/OpenBTS/
touch /var/run/OpenBTS/TransactionTable.db


Jika Menggunakan RFX 1800 daughter board

RFX board yang biasanya di beli adalah RFX 1800. Sebaiknya di flash EEPROM agar bekerja di 900MHz / menjadi RFX 900, jika terpaksa juga menggunakan RFX 1800, kita perlu mengedit database konfigurasi OpenBTS agar beroperasi di band 1800MHz channel 860 

vi ~/src/openbts-2.8.0/openbts/trunk/apps/OpenBTS.example.sql

Agar 

INSERT INTO "CONFIG" VALUES('GSM.Radio.Band','1800',1,0,'The GSM operating band.  Valid values are 850 (GSM850), 900 (PGSM900), 1800 (DCS1800) and 1900 (PCS1900).  For most Range models, this value is dictated by the hardware and should not be changed.  Static.');
INSERT INTO "CONFIG" VALUES('GSM.Radio.C0','860',1,0,'The C0 ARFCN.  Also the base ARFCN for a multi-ARFCN configuration.  Static.');

Instalasi Database Konfigurasi OpenBTS 

cd ~/src/openbts-2.8.0/openbts/trunk
sudo mkdir /etc/OpenBTS
rm -Rf /etc/OpenBTS/OpenBTS.db
sudo sqlite3 -init ./apps/OpenBTS.example.sql /etc/OpenBTS/OpenBTS.db ".quit"

Instalasi Subscriber Registry

Lakukan 

cd ~/src/openbts-2.8.0/subscriberRegistry/trunk/configFiles
sudo mkdir /var/lib/asterisk/
sudo mkdir -p /var/lib/asterisk/sqlite3dir
sudo rm -Rf /var/lib/asterisk/sqlite3dir/sqlite3.db
sudo sqlite3 -init subscriberRegistryInit.sql /var/lib/asterisk/sqlite3dir/sqlite3.db ".quit"

Instalasi Sipauthserve

Sipauthserve adalah daemon yang memberikan SIP authentication services. Variabel SIP.Proxy.Registration di OpenBTS harus menunjuk pada hostname & port Sipauthserve. OpenBTS harus sudah di buat sebelum membuat Sipauthserve.

Compile Sipauthserve 

cd ~/src/openbts-2.8.0/subscriberRegistry/trunk
make

Setup database untuk Sipauthserve 

mkdir /etc/OpenBTS
rm -Rf /etc/OpenBTS/sipauthserve.db
cd ~/src/openbts-2.8.0/subscriberRegistry/trunk
sudo sqlite3 -init sipauthserve.example.sql /etc/OpenBTS/sipauthserve.db ".quit"

Instalasi Smqueue

Smqueue dapat di instalasi dengan melakukan langkah berikut 

cd ~/src/openbts-2.8.0/smqueue/trunk
autoreconf -i
./configure 
make clean
make 
make install

Selanjutnya, inisialisasi konfigurasi database OpenBTS 

cd ~/src/openbts-2.8.0/smqueue/trunk
rm -Rf /etc/OpenBTS/smqueue.db
sudo sqlite3 -init smqueue/smqueue.example.sql /etc/OpenBTS/smqueue.db ".quit"

Menjalankan OpenBTS

Pastikan Yate sudah di Instalasi.

Lakukan di tiga (3) windows yang berbeda 

cd ~/src/openbts-2.8.0/subscriberRegistry/trunk/
./sipauthserve &

mkdir -p /var/lib/OpenBTS
touch /var/lib/OpenBTS/smq.cdr
cd ~/src/openbts-2.8.0/smqueue/trunk/smqueue/
./smqueue &

cd ~/src/yate
rm -Rf /var/log/yate
./run -t -l /var/log/yate -vvvv -c /usr/local/etc/yate -m /usr/local/lib/yate -e /usr/local/share/yate -d

mkdir /var/run/OpenBTS/
touch /var/run/OpenBTS/TransactionTable.db
cd ~/src/openbts-2.8.0/openbts/trunk/apps
./OpenBTS &

Edit Konfigurasi

cd ~/src/openbts-2.8.0/openbts/trunk/apps/
./OpenBTSCLI

Parameter yang perlu di ubah 

config Control.LUR.OpenRegistration \W+
config GSM.Radio.Band 900
config GSM.Radio.C0 20
config GSM.Identity.MCC 001
config GSM.Identity.MNC 01
config GSM.Identity.BSIC.NCC 0
config GSM.Identity.ShortName OpenBTS
config GSM.CellSelection.NCCsPermitted 1
config GSM.CellSelection.BSIC.BCC 101
config GSM.Identity.LAC 1001
config GSM.Identity.CID 101
config SIP.Local.IP 192.168.0.22
config SIP.Proxy.Registration 192.168.0.3:5064
config SIP.Proxy.SMS 192.168.0.3:5063
config SIP.Proxy.Speech 192.168.0.3:5060

config save

Debug Transceiver

cd ~/src/openbts-2.8.0/openbts/trunk/apps/

SOLUSI:

  • Naikan sleep() di OpenBTS.cpp & compile ulang
vi ~/src/openbts-2.8.0/openbts/trunk/apps/OpenBTS.cpp 

sleep(8);

killall transceiver
cd ~/src/openbts-2.8.0/openbts/trunk/apps
./OpenBTS &
