0x01环境搭建

PC：Ubuntu16.04

HardWare：ip.access nano3G

SoftWare：Osmocom

1.1 安装交叉编译环境

sudo apt-get update

sudo apt-get install libtool shtool autoconf git-core pkg-config make gcc build-essential libgmp3-dev libmpfr-dev libx11- libx11-dev texinfo flex bison libncurses5 libncurses5-dbg libusb-0.1- libpcsclite1 libccid pcscd libncurses5-dev libncursesw5 libncursesw5-dbg libncursesw5-dev zlibc zlib1g-dev libmpfr4 libmpc-dev libpcsclite-dev
sudo ldconfig

mkdir osm
cd osm
mkdir build install src
wget http://bb.osmocom.org/trac/raw-attachment/wiki/GnuArmToolchain/gnu-arm-build.3.sh
cd src
wget http://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.bz2
wget http://ftp.gnu.org/gnu/binutils/binutils-2.21.1a.tar.bz2
wget ftp://sources.redhat.com/pub/newlib/newlib-1.19.0.tar.gz

cd ..
chmod +x gnu-arm-build..sh
sudo bash gnu-arm-build..sh

1.2 设置交叉编译环境变量

cd install/bin
pwd

vi ~/./.bashrc
export PATH=$PATH:/home/$username(change this to your name)/osm/install/bin

#save and quit
source ~/.bashrc

0x02 源码编译CalypsoBTS

2.1 编译libosmo-dsp

git clone git://git.osmocom.org/libosmo-dsp.git
cd libosmo-dsp/
autoreconf -i
./configure
make
sudo make install
cd ..

2.2 编译osmocom-bb

git clone git://git.osmocom.org/osmocom-bb.git trx
cd trx/
git checkout jolly/testing
cd src/

# 需要 TX 功能支持
# 取消target/firmware/Makefile代码中'CFLAGS += -DCONFIG_TX_ENABLE' 前边的注释
# 并在make时启用transceiver功能支持
make HOST_layer23_CONFARGS=--enable-transceiver 

2.3 安装依赖包

sudo apt-get install sqlite3 libdbi-dev libdbd-sqlite3 libsctp-dev

2.4 编译 Ortp

wget http://download.savannah.gnu.org/releases/linphone/ortp/sources/ortp-0.22.0.tar.gz
tar -xvf ortp-0.22..tar.gz
cd ortp-0.22./
./configure
make
sudo make install
sudo ldconfig
cd ..

2.5 编译libosmo-abis

git clone git://git.osmocom.org/libosmo-abis.git
cd libosmo-abis
autoreconf -i
./configure
make
sudo make install
sudo ldconfig
cd ..

2.6 编译libosmo-netif

git clone git://git.osmocom.org/libosmo-netif.git
cd libosmo-netif/
autoreconf -i
./configure
make
sudo make install
sudo ldconfig
cd ..

2.7 编译openbsc

编译Openbsc时需用到PCAP库文件，编译前先搜索&安装依赖包：

apt-cache search PCAP
sudo pat-get install libpcap-dev libpcap0. libpcap0.-dbg libpcap0.-dev
sudo ldconfig

git clone git://git.osmocom.org/openbsc.git
cd openbsc/openbsc/
autoreconf -i
./configure
make
sudo make install
cd ../..

git clone git://git.osmocom.org/openbsc.git
cd openbsc/openbsc/
autoreconf -i
./configure
make
sudo make install
cd ../..

2.8 编译osmo-bts

git clone git://git.osmocom.org/osmo-bts.git
cd osmo-bts
autoreconf -i
./configure --enable-trx
make
sudo make install
cd ..

2.9 创建OpenBSC配置文件

#如果配置文件不存在需要先创建 Create the configuration folder if it isn't exist yet
mkdir ~/.osmocom
cd ~/.osmocom
touch ~/.osmocom/open-bsc.cfg
touch ~/.osmocom/osmo-bts.cfg

0x03 源码编译Cellular Infrastructure

3.1 克隆源码

git clone git://git.osmocom.org/libosmocore
git clone git://git.osmocom.org/libosmo-abis
git clone git://git.osmocom.org/openbsc
git clone git://git.osmocom.org/libosmo-netif
git clone git://git.osmocom.org/libosmo-sccp
git clone git://git.osmocom.org/libsmpp34
git clone git://git.osmocom.org/openggsn

3.2 下载&执行自动编译脚本

wget https://osmocom.org/attachments/download/2438/build_2G.sh
chmod   build_2G.sh
sudo bash build_2G.sh

0x04 配置OpenBSC

4.1 启动BTS

终端1：

osmo-nitb -c ~/.osmocom/open-bsc.cfg -l ~/.osmocom/hlr.sqlite3 -P -C --debug=DRLL:DCC:DMM:DRR:DRSL:DNM

终端2：

telnet localhost 

4.2 配置IP

PC

IP：192.168.31.147 (通过WiFi连接)

路由器

IP:192.168.31.1

3G Access Point

IP:未知

方法1：进入路由后台，查找3G Access Point IP

方法2：通过abissip-find找到3G Access Point IP

cd openbsc/openbsc/src/ipaccess
#or
cd openbsc/openbsc/build-2G/src/ipaccess

sudo ./abisip-find

4.3 Telnet连入3G Access Point

telnet 3G Access Point's IP 8090

4.4 SSH连入

ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 root@192.168.31.136
password:newsys
