使用OpenBTS搭建GSM测试网络
1. 环境搭建
下载ubuntu-16.04.4-desktop-amd64.iso，安装使用一台全新的机器，防止因依赖问题导致的报错。
SDR硬件，usrp B210
1.1 更新
sudo apt-get install software-properties-common python-software-properties
sudo add-apt-repository ppa:git-core/ppa
sudo apt-get update
sudo apt-get install git
1.2 搭建OpenBTS开发环境
mkdir sdr //新建sdr文件夹
cd sdr //进入该文件夹
git clone https://github.com/RangeNetworks/dev.git
cd dev
./clone.sh //从GitHub克隆代码
./switchto.sh master //切到master分支
./build.sh B210
编译下载的源码，因为使用的是USRP B210 build脚本后加SDR硬件 ,如果使用的是USRP N200 则执行./build.sh N200（过程中需从谷歌下载源码，建议全程，否则会报错！)
编译过程根据网络、机器性能而异，通常在30-45分钟左右，编译完成后,ubuntu自动安装GnuRadio、USRP的UHD驱动等相关SDR环境，但USRP的固件还需手动下载：

编译完成后也会在BUILD目录下生成一个以编译时间为名的文件，如果系统为32bit编译后则在该目录下生成i386.deb的软件包，如果系统为64bit则生成amd64.deb ：
1.3 更新&安装依赖包
sudo apt-get install software-properties-common python-software-properties
sudo add-apt-repository ppa:chris-lea/zeromq
sudo apt-get update
1.4 安装编译完成的DEB软件包
需注意是否有报错：
cd dev/BUILD/2018-03-02--15-29-38 sudo dpkg -i libcoredumper1_1.2.1-1_i386.deb libcoredumper-dev_1.2.1-1_i386.deb sudo dpkg -i liba53_0.1_i386.deb sudo dpkg -i range-configs_5.0_all.deb sudo dpkg -i range-asterisk*.deb sudo dpkg -i sipauthserve_5.0_i386.deb sudo dpkg -i smqueue_5.0_i386.deb sudo dpkg -i openbts_5.0_i386.deb如遇到安装失败运行下面安装依赖指令： sudo apt-get install -f
2. 开启数据转发、配置iptables
因为OpenBTS基站的GPRS网络流量是基于PC机，所以在开启基站GPRS功能前，需要开启数据包转发以及配置Iptables防火墙规则。
2.1 开启数据包转发：
ubuntu开数据转发需以root身份执行，如果不是root用户，即使使用sudo也无法开启：
sudo su
echo 1 >> /proc/sys/net/ipv4/ip_forward
2.2 配置iptables规则：
/etc/OpenBTS/iptables.rules 配置规则文件内容如下：
# Generated by iptables-save v1.4.4
*nat
:PREROUTING ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A POSTROUTING -o eth0 -j MASQUERADE
COMMIT
# Generated by iptables-save v1.4.4
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
COMMIT某些情况下机器的网卡并非eth0 ,所以需要根据自身实际情况，灵活地修改配置文件。
sudo iptables-restore < /etc/OpenBTS/iptables.rules
iptables -t nat -L -n -v
3.3 加载数据库
cd sdr/dev/openbts/apps
sudo sqlite3 -init OpenBTS.example.sql /etc/OpenBTS/OpenBTS.db ".quit"
cd sdr/dev/subscriberRegistry/apps
sudo sqlite3 -init sipauthserve.example.sql /etc/OpenBTS/sipauthserve.db ".quit"
cd sdr/dev/smqueue/smqueue
sudo sqlite3 -init smqueue.example.sql /etc/OpenBTS/smqueue.db ".quit"3.4 配置asterisk
Asterisk是运行在Linux上来实现用户电话交换的IP-PBX系统开源软件，支持各种的VOIP协议。Asterisk提供了很多以前只有昂贵、专业的PBX系统才支持的功能，如：会议电话、语音信箱、交互式语音应答、自动电话转接。
在/etc/asterisk/目录中需要修改sip.conf、extensions.conf 具体方法：将手机的IMSI国际用户识别码和分配的号码登记数据asterisk中，也就是将数据写入sip.conf、extensions.conf两个配置文件。
sip.conf:

Default: rfc2833 ; Other options: ; info : SIP INFO messages (application/dtmf-relay) ; shortinfo : SIP INFO messages (application/dtmf) ; inband : Inband audio (requires 64 kbit codec -alaw, ulaw) ; auto : Use rfc2833 if offered, inband otherwise canreinvite=no ; no reinvites from Asterisk directmedia=no ; Asterisk by default tries to redirect the ; RTP media stream to go directly from ; the caller to the callee. Some devices do not ; support this (especially if one of them is behind a NAT). ; The default setting is YES. If you have all clients ; behind a NAT, or for some other reason want Asterisk to ; stay in the audio path, you may want to turn this off. ; This setting also affect direct RTP ; at call setup (a new feature in 1.4 - setting up the ; call directly between the endpoints instead of sending ; a re-INVITE). callcounter=yes ; Enable call counters on devices. This can be set per ; device too.#include sip-custom-register.conf [CodecBTS](!) disallow=all ; need to disallow=all before we can use allow allow=gsm ; GSM allow=ulaw ; ISDN US allow=alaw ; ISDN EU [optionsBTS](!) type=peer context=from-openBTS dtmfmode=rfc2833 canreinvite=no qualify=no ; openbts do not support OPTION insecure=port,invite ;If you need to make any changes please add them to sip-custom-contexts.conf #include sip-custom-contexts.conf ;openbts [IMSI460010100001101] callerid=1101 canreinvite=no type=friend context=sip-external allow=gsm host=dynamic dtmfmode=info [IMSI460010100001102] callerid=1102 canreinvite=no type=friend context=sip-external allow=gsm host=dynamic dtmfmode=info
callerid=1102,表示将IMSI为460010100001102的手机分配号码1102；
canreinvite=no，表示被呼叫的手机一旦建立连接后OpenBTS将不再发送重新邀请的指令；
context=sip-external，表示允许外部未分配号码的匿名电话呼入。

4. 配置基站
刚搭建完成的基站由于天线功率过大以及手机跟基站的距离太近等原因，可能会导致手机不能正常加入到基站，这时需要配置加入基站的条件以及设置天线功率：
命令：
help:查看命令；
version:查看版本信息；
notices:查看license信息；
quit:退出命令行界面；
运行help,查看运行命令：
允许任意机器接入：
OpenBTS> config Control.LUR.OpenRegistration .*
Control.LUR.OpenRegistration changed from "" to ".*"设置天线功率：
OpenBTS> devconfig GSM.Radio.RxGain 18
GSM.Radio.RxGain changed from "50" to "18"
GSM.Radio.RxGain is static; change takes effect on restart设置基站频段：
OpenBTS> config GSM.Radio.Band 900
GSM.Radio.Band changed from "850" to "900"
GSM.Radio.Band is static; change takes effect on restart 设置欢迎短信：
config Control.LUR.NormalRegistration.Message Welcome to BTS 1设置基站名：
config GSM.Identity.ShortName GroundControl将基站设置为测试网络：
config Identity config GSM.Identity.MCC 001将基站设置为国内： MCC460 为中国
config GSM.Identity.MCC 460设置运营商为联通：
config GSM.Identity.MNC 01 设置运营商为移动：
config GSM.Identity.MNC 00 设置ARFCN、LAC、BCC
网络色码，NCC，一般用于标识运营商；基站色码，BCC，区分同一运营商下的相同BCCH的不同基站。
一般采用BCCH频点和BSIC来联合标识小区，BSIC=NCC+BCC。在TD和WCDMA里，存在PLMN，PLMN=MCC+MNC，其中MCC为移动国家码，MNC为移动网络码标识运营商。
基站切换的时候,主要是通过CI、BCCHBSIC等信息寻找目标小区,当同时检测到邻区列表里出现同BCCH同扰码组的小区时,容易出现切换失败。
OpenBTS> config GSM.Radio.C0 168
GSM.Radio.C0 changed from "151" to "168"
GSM.Radio.C0 is static; change takes effect on restart
OpenBTS> config GSM.Identity.BSIC.BCC 3
GSM.Identity.BSIC.BCC changed from "2" to "3"
OpenBTS> config GSM.Identity.LAC 1001
GSM.Identity.LAC changed from "1000" to "1001"
OpenBTS> config GSM.Identity.CI 11
GSM.Identity.CI changed from "10" to "11"
用户管理
在3.4配置asterisk再我们给部分用户配置了callerid号码，启动OpenBTS后可通过NodeManager目录下的nmcli.py脚本进行用户管理：
cd sdr/dev/openbts/NodeManager/添加用户示例：
nmcli.py脚本是Range提供的另外一种配置方式，其基于Json，而且据说商业版OpenBTS的Web管理界面就是使用这种方式来对OpenBTS进行配置的.
./nmcli.py sipauthserve subscribers create name imsi msisdn
将123456 （MSISDN码）分配到IMSI 码为46001658*****19的LG G3设备中
./nmcli.py sipauthserve subscribers create "LG G3" IMSI46001658*****19 123456读取已录入信息：
nano@nano:~/sdr/dev/openbts/NodeManager$ ./nmcli.py sipauthserve subscribers read raw request: {"command":"subscribers","action":"read","key":"","value":""} raw response: { "code" : 200, "data" : [ { "imsi" : "IMSI460010100001101", "msisdn" : "1101", "name" : "1101" }, { "imsi" : "IMSI460010100001102", "msisdn" : "1102", "name" : "1102" } ] }
两台手机可以互相收发短信和语音拨打
查看接入的手机：
语音拨打后asterisk截图如下：
OpenBTS Usage
点击测试网络，然后会提示注册入网，然后会收到101所发送的短信，内容默认为：
Welcome to the test network,your IMSI is :
之后你可以回复想要为该手机使用的手机号码，比如1234567，要求为7-10位，这样相当于在基站侧注册完成，即phone number与IMSI绑定并写入了数据库；
然后即可进行短信的发送以及电话的通信了：
OpenBT SIntroduction
相信大家在启动OpenBTS的时候都在想“为什么OpenBTS需要使用以下的命令来进行启动与停止？”
OpenBTS启动：
sudo start sipauthserve
sudo start smqueue
sudo start openbts
sudo start asterisk
OpenBTS 停止：
sudo stop sipauthserve
sudo stop smqueue
sudo stop openbts
sudo stop asterisk
原因很简单，那就是OpenBTS本身就是由几个开源软件共同组成的，而其中的openbts只是来根据3GPP标准进行几个软件功能的整合，如smqueue负责短信的发送，asterisk负责语音通话，而sipauthserve负责鉴权以及数据库的存储、sip协议等。
（1） Asterisk 是负责处理SIM INVITE请求的VOIP 网关，其能够建立通话的各个分支，并将它们连接在一起；
（2） SIPAuthServe，即SIP Authorization Server，当手机试图接入OpenBTS时，由SIPAuthServe 处理SIP REGISTER请求；
（3） SMQueue ，即SIP MESSAGE Queue，当手机发送短信的时候，由SMQueue 来处理SIP MESSAGE请求；
（4） OpenBTS 首先负责和GSM空中接口的连接，即其余GSM终端通过空中接口进行通信，其次，OpenBTS将信息转化为SIP以及RTP信息，通过IP网络与以上几个部分进行通信，共同实现核心网的功能。
