OAI 搭建文档

[draft] 更新于2020年6月25日

0. OAI 项目结构

整个 OAI 系统分为如下三个部分，需要分别配置在不同机器上。

1. EPC（官方文档也称为 Core Network）
2. eNB（官方文档将其与 UE 合称为 RAN）
3. UE（官方文档将其与 eNB 合称为 RAN）

最初三个组件位于同一 GitLab Eurecom server，后来 EPC 组件拆分出来，不再维护的旧版仍在 GitLab Eurecom server 且拆分为两个仓库，新版位于 GitHub。

EPC 组件文档：https://github.com/OPENAIRINTERFACE/openair-cn/wiki

RAN 组件文档：https://gitlab.eurecom.fr/oai/openairinterface5g/-/wikis/home

0.1. OAI 网络结构示意图

1. EPC 配置

对于 EPC（Core Network），旧版存在于 GitLab Eurecom server，由于不计划使用不再做介绍。新版存在于 GitHub：https://github.com/OPENAIRINTERFACE/openair-cn ，文档在该项目的 WiKi：https://github.com/OPENAIRINTERFACE/openair-cn/wiki

官方文档在 Ubuntu 主机上使用 uvtool 安装 Ubuntu 18.04 LTS 虚拟机进行部署（ https://github.com/OPENAIRINTERFACE/openair-cn/wiki/OpenAirSoftwareSupport ），本文档在 macOS 主机上使用 Parallel Desktop 安装 Ubuntu 18.04 LTS 虚拟机进行部署测试。

注意硬件要求，官方文档中虚拟机是 2 CPU 4GB 内存。

EPC 组件版本：openair-cn 使用 commit d1d0e45，openair-cn-cups 使用 commit 5ca3839

1.1. Download EPC source code

1.1.1. Install curl git

sudo apt install curl git

1.1.2. Get source code

cd ~
git clone https://github.com/OPENAIRINTERFACE/openair-cn.git
git clone https://github.com/OPENAIRINTERFACE/openair-cn-cups.git

1.2. Install HSS

1.2.1. Modify script

sudo gedit ~/openair-cn/build/tools/build_helper.cassandra

$SUDO $INSTALLER install $OPTION curl oracle-java8-installer

改为

$SUDO $INSTALLER install $OPTION curl openjdk-8-jre

curl https://www.apache.org/dist/cassandra/KEYS | $SUDO apt-key add -

改为

curl https://downloads.apache.org/cassandra/KEYS | $SUDO apt-key add -

1.2.2. Build Cassandra

cd ~/openair-cn/scripts/
./build_cassandra --check-installed-software --force

1.2.3. Set the JRE version 8 as default

sudo service cassandra stop
sudo update-alternatives --config java
# select jre version 8
...
sudo service cassandra start

在其中第二行，有可能输出类似如下，则表示只有一个 JRE 版本，不需要再设置默认版本

There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java
Nothing to configure.

1.2.4. Verify that Cassandra is installed and running

nodetool status

输出应类似如下：

Datacenter: datacenter1
=======================
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
--  Address    Load       Tokens  Owns (effective)  Host ID                               Rack
UN  127.0.0.1  51.69 KB   256     100.0%            fa761e10-4118-4a99-9a2e-829e7cdd8e82  rack1

1.2.5. Modify Cassandra configuration

Stop Cassandra and cleanup the log files before modifying the configuration

sudo service cassandra stop
sudo rm -rf /var/lib/cassandra/data/system/*
sudo rm -rf /var/lib/cassandra/commitlog/*
sudo rm -rf /var/lib/cassandra/data/system_traces/*
sudo rm -rf /var/lib/cassandra/saved_caches/*

修改文件，也可以使用其他编辑器如 vim

sudo gedit /etc/cassandra/cassandra.yaml

改为如下所示，修改“…”间对应的部分， 替换为 HSS 将要连接的 Cassandra 服务器地址，在本教程情况下使用本机地址（127.0.0.1）

...
cluster_name: 'HSS Cluster'
...
# OAI Note: no to change Cassandra_Server_IP that is already 127.0.0.1
seed_provider:
- class_name: org.apache.cassandra.locator.SimpleSeedProvider
- seeds: "<Cassandra_Server_IP>"
...
listen_address: <Cassandra_Server_IP>
...
rpc_address: <Cassandra_Server_IP>
...
# OAI Note: seems to be this option that is working ()
# endpoint_snitch: SimpleSnitch
endpoint_snitch: GossipingPropertyFileSnitch
...

启动 Cassandra

sudo service cassandra start

确认 Cassandra 服务状态

sudo systemctl status cassandra

输出类似如下

● cassandra.service - LSB: distributed storage system for structured data
   Loaded: loaded (/etc/init.d/cassandra; generated)
   Active: active (running) since Thu 2019-05-23 10:26:51 UTC; 1h 54min ago

May 23 10:26:51 test-install-openair-cn systemd[1]: Started LSB: distributed storage system for structured data.

确认完毕使用快捷键 ctrl + c 结束状态查询

1.2.6. Install HSS software dependancies

./build_hss_rel14 --check-installed-software --force

需要一些时间，成功输出类似如下：

...
-- Installing: /usr/local/lib/cmake/pistache/PistacheConfig.cmake
~/openair-cn/scripts
HSS software installation successful
HSS not compiled, to compile it, re-run build_hss without -i option

1.2.7. Build HSS

./build_hss_rel14 --clean

成功输出类似如下：

mkdir: created directory '/home/ubuntu/openair-cn/scripts/../build/hss_rel14/build'

1.2.8. Populate users table

配置自己的用户参数，这里使用默认值，依次运行如下命令

Cassandra_Server_IP='127.0.0.1'

cqlsh --file ../src/hss_rel14/db/oai_db.cql $Cassandra_Server_IP

./data_provisioning_users --apn default.ng4T.com --apn2 internet --key fec86ba6eb707ed08905757b1bb44b8f --imsi-first 208931234561000 --msisdn-first 001011234561000 --mme-identity mme.ng4T.com --no-of-users 20 --realm ng4T.com --truncate True  --verbose True --cassandra-cluster $Cassandra_Server_IP

输出类似如下：

1.2.9. Create HSS configuration files

# prompt has been removed for easier Ctrl+C Ctrl+V
# cd $OPENAIRCN_DIR/scripts

openssl rand -out $HOME/.rnd 128

PREFIX='/usr/local/etc/oai'
sudo mkdir -p $PREFIX
sudo chmod 777 $PREFIX
sudo mkdir $PREFIX/freeDiameter
sudo chmod 777 $PREFIX/freeDiameter

# freeDiameter configuration files
sudo cp ../etc/acl.conf ../etc/hss_rel14_fd.conf $PREFIX/freeDiameter
sudo chmod 666 $PREFIX/freeDiameter/acl.conf $PREFIX/freeDiameter/hss_rel14_fd.conf

# HSS configuration files
sudo cp ../etc/hss_rel14.conf ../etc/hss_rel14.json $PREFIX
sudo chmod 666 $PREFIX/hss_rel14.conf $PREFIX/hss_rel14.json

declare -A HSS_CONF
HSS_CONF[@PREFIX@]=$PREFIX
HSS_CONF[@REALM@]='ng4T.com'
HSS_CONF[@HSS_FQDN@]="hss.${HSS_CONF[@REALM@]}"
HSS_CONF[@cassandra_Server_IP@]='127.0.0.1' 
HSS_CONF[@cassandra_IP@]='127.0.0.1' # TODO harmonize these 2
HSS_CONF[@OP_KEY@]='1006020f0a478bf6b699f15c062e42b3'
HSS_CONF[@ROAMING_ALLOWED@]='true'

for K in "${!HSS_CONF[@]}"; do 
  egrep -lRZ "$K" $PREFIX | xargs -0 -l sed -i -e "s|$K|${HSS_CONF[$K]}|g"
done

### freeDiameter certificate
../src/hss_rel14/bin/make_certs.sh hss ${HSS_CONF[@REALM@]} $PREFIX

# Finally customize the listen address of FD server (if necessary because FD binds by default on available interfaces)
# set in $PREFIX/freeDiameter/hss_rel14_fd.conf and uncomment the following line
sudo sed -i -e 's/#ListenOn/ListenOn/g' $PREFIX/freeDiameter/hss_rel14_fd.conf

1.2.10. Modify log file directory

修改配置中日志目录

sudo gedit /usr/local/etc/oai/hss_rel14.json

修改如下的四项内容的值为如下

"logname": "/var/log/hss.log"
"statlogname": "/var/log/hss_stat.log"
"auditlogname": "/var/log/hss_audit.log"
"ossfile": "~/openair-cn/etc/oss.json"

创建文件并授权

sudo touch /var/log/hss.log
sudo touch /var/log/hss_stat.log
sudo touch /var/log/hss_audit.log

sudo chmod 777 /var/log/hss.log
sudo chmod 777 /var/log/hss_stat.log
sudo chmod 777 /var/log/hss_audit.log

1.2.11. Update OPC Cassandra DB

运行

oai_hss -j $PREFIX/hss_rel14.json --onlyloadkey

输出应类似如下：

Options::jsonConfig            : /usr/local/etc/oai/hss_rel14.json
Options::diameterconfiguration : /usr/local/etc/oai/freeDiameter/hss_rel14_fd.conf

输出不完全一致，可能由于官方文档没有同步更新？部分数值如 IMSI、KEY 等乱码，可能由于数据库编码问题？

1.3. Install MME

1.3.1. Install MME software dependencies

cd ~/openair-cn/scripts/
./build_mme --check-installed-software --force

输出类似如下

...
Processing triggers for mime-support (3.60ubuntu1) ...
Setting up unzip (6.0-21ubuntu1) ...
Processing triggers for man-db (2.8.3-2ubuntu0.1) ...
sh: 0: getcwd() failed: No such file or directory
MME software installation successful
MME not compiled, to compile it, re-run build_mme without -i option

1.3.2. Build MME

cd ~/openair-cn/scripts/
./build_mme --clean

输出类似如下

Clean the build generated files (build from scratch)
mkdir: created directory 'build'
Build type is Debug
Architecture is x86_64
git found: /usr/bin/git
NETTLE VERSION_INSTALLED  = 3.4
NETTLE_VERSION_MAJOR = 3
NETTLE_VERSION_MINOR = 4

mme compiled
'/home/ubuntu/openair-cn/build/mme/build/mme' -> '/usr/local/bin/mme'
mme installed

1.3.3. Create MME configuration files

安装 net-tools

sudo apt install net-tools

下面“创建 MME 配置文件”命令的第5行、第6行两个 ifconfig 的网卡名称根据自己实际情况修改冒号前部分，同时修改下面赋值语句中3处。共计5处。

使用命令 ifconfig -a 查看自己的网卡情况，例如如下显示情况则分别为 enp0s5:m11、enp0s5:m1c

enp0s5: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
                ...
lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
                ...

# Generate freeDiameter certificate
sudo ./check_mme_s6a_certificate $PREFIX/freeDiameter mme.${MME_CONF[@REALM@]}

mkdir 报 File exists 可以忽略

最后一行命令运行中可能出现红色 File /usr/local/etc/oai/freeDiameter/mme.cert.pem not found
MME S6A: Did not find valid certificate in /usr/local/etc/oai/freeDiameter 提示，是正常现象

最后输出类似如下

  ret=$?;[[ ret -ne 0 ]] && echo "Tried to replace $K with ${SPGWU_CONF[$K]}"
done

修改 SPGW-U 配置文件中的自定义网络配置参数

sudo gedit /usr/local/etc/oai/spgw_u.conf

SPGW-C_LIST 部分中的第一行改为 {IPV4_ADDRESS="172.55.55.101";}

PDN_NETWORK_LIST 部分使用默认值，不需要修改

1.4.2. Install SPGW-C

1.4.2.1. Install SPGW-C software dependencies

cd ~/openair-cn-cups/
cd ./build/scripts
./build_spgwc -I -f

1.4.2.2. Build SPGW-C

As a starting point, you can start with a Debug build, then you can change the build type Check build types with ‘./build_spgwc -h’

# Set up interfaces for SPGW-U
sudo ifconfig enp0s5:sxu 172.55.55.102 up   # SPGW-U SXab interface
sudo ifconfig enp0s5:s1u 192.168.248.159 up # SPGW-U S1U interface

cd ~/openair-cn-cups/build/scripts
PREFIX='/usr/local/etc/oai'
sudo spgwc -c $PREFIX/spgw_c.conf

1.5.3.2. Run SPGW-U

【不做】每次重新启动计算机后需要运行一次如下命令，以指定用户流量所使用的网关。根据实际情况修改网关和用户流量来源地址 (PDN)

echo '200 lte' | sudo tee --append /etc/iproute2/rt_tables
# Here the gateway is at 192.168.0.1
sudo ip route add default via 192.168.0.1 dev enp0s5 table lte
# you will have to repeat the following line for each PDN network set in your SPGW-U config file
sudo ip rule add from 12.0.0.0/8 table lte

注意：先运行 SPGW-C 再运行 SPGW-U

cd ~/openair-cn-cups/build/scripts
PREFIX='/usr/local/etc/oai'
sudo spgwu -c $PREFIX/spgw_u.conf

2. RAN（eNB 和 UE） 配置

官方文档 https://gitlab.eurecom.fr/oai/openairinterface5g/-/wikis/home

2.1. Requirements for RAN

根据官方文档介绍，选择较新版本进行配置（starting master tag v1.1.0 and develop tag 2019.w09），操作系统 Ubuntu 16.04 with low-latency kernel 4.4.0 or higher

具体来说，本文档在 macOS 主机上使用 Parallel Desktop 安装 Ubuntu 16.04 LTS 进行部署测试，RAN 版本使用 master branch commit 7cc5a63acaf77d5e1e4c4b023958b329ae4ece3d

2.1.1. System requirements (Hardware compatibility)

3代 Intel i5 以上处理器，至少4个核心

Note: When running the software on virtualized environment (containers, VMs), make sure that the access to the RF interface is granted (e.g. passthru) and CPU flags are set. In addition, make sure that low latency kernel is installed when using VMs and that enough CPUs processing is available.

2.1.2. Kernel Setups - Main Installation (Software compatibility)

2.1.2.1. Install the low-latency kernel

sudo apt-get install linux-image-lowlatency linux-headers-lowlatency

显示内核启动顺序

grep menuentry /boot/grub/grub.cfg

输出类似如下，确认存在类似 Ubuntu, with Linux 4.4.0-184-lowlatency，安装正确

修改 grub 文件

sudo gedit /etc/default/grub

GRUB_DEFAULT=0

改为

GRUB_DEFAULT="Advanced options for Ubuntu>Ubuntu, with Linux 4.4.0-184-lowlatency" （对应的版本号）

更新 grub 以启用

sudo update-grub

重新启动 sudo reboot 后，输入 uname -r 查看内核版本，若为 4.4.0-184-lowlatency 即为成功

2.1.2.2. Power management

Remove all power management features in the BIOS (sleep states, in particular C-states) and CPU frequency scaling (Intel SpeedStep). In some cases, you can also do this with cpufreqtool. Also, disable hyperthreading in BIOS and make sure its turned off in Linux

2.1.2.2.1. Check CPU frequency

check this using this command: watch grep \"cpu MHz\" /proc/cpuinfo

2.1.2.2.2. Disable pstate & cstate

修改 grub 文件

sudo gedit /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

改为

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=disable processor.max_cstate=1 intel_idle.max_cstate=0 idle=poll"

更新 grub 以启用

sudo update-grub

重新启动 sudo reboot

2.1.2.2.3. Blacklist intel_powerclamp

修改文件，如果不存在则新建

sudo gedit /etc/modprobe.d/blacklist.conf

在文件末尾添加如下内容，建议保留一行空行

# blacklist the intel_powerclamp module
# for OAI RAN build power management requirements
blacklist intel_powerclamp

重新启动 sudo reboot

2.1.2.2.4. Disable power management from BIOS

Disable hyperthreading, CPU frequency control, C-States, P-States and any other power management from BIOS.

根据实际情况进入 BIOS 设置，虚拟机软件则一般使用对应的配置菜单，打开 CPU 设置中类似 “PMU 虚拟化” 的选项。

2.1.2.2.5. Install i7z utility to check the cpu

sudo apt-get install i7z
sudo i7z

输出类似如下

Cpu speed from cpuinfo 2903.00Mhz
cpuinfo might be wrong if cpufreq is enabled. To guess correctly try estimating via tsc
Linux's inbuilt cpu_khz code emulated now
True Frequency (without accounting Turbo) 2903 MHz

  Max Frequency without considering Turbo 2903.00 MHz (100.10 x [29])
  Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is  0x/0x/0x/0x
  Real Current Frequency 3500.91 MHz [100.10 x 34.97] (Max of below)
        Core [core-id]  :Actual Freq (Mult.)      C0%   Halt(C1)%  C3 %   C6 %  Temp      VCore

        Core 2 [1]:       3496.15 (34.93x)      96.2       0       0       0    97      0.9062
        Core 3 [2]:       3500.91 (34.97x)      96.6       0       0       0    97      0.9062
        Core 4 [3]:       3496.96 (34.93x)      96.2       0       0       0    97      0.9062



C0 = Processor running without halting
C1 = Processor running with halts (States >C0 are power saver modes with cores idling)
C3 = Cores running with PLL turned off and core cache turned off
C6, C7 = Everything in C3 + core state saved to last level cache, C7 is deeper than C6
  Above values in table are in percentage over the last 1 sec
[core-id] refers to core-id number in /proc/cpuinfo
'Garbage Values' message printed when garbage values are read
  Ctrl+C to exit

CPU 频率不应该有超过1-2 Hz 的改变，除了 C0 外不应该有其他 C-state，如果不正确则必须修正，否则 eNB/UE/RRH 会有运行问题

2.1.2.3. Disable CPU Frequency scaling

Install cpufrequtils:

sudo apt-get install cpufrequtils

Then edit the following file (if it doesn’t exist, create it):

sudo gedit /etc/default/cpufrequtils

And add the following line to it:

GOVERNOR="performance"

Save and exit.

Now you need to disable ondemand daemon, otherwise after you reboot the settings will be overwriten.

sudo update-rc.d ondemand disable
sudo /etc/init.d/cpufrequtils restart

You can check your settings with:

cpufreq-info

It will show a block of information for every core your processor has. Just check if all of then are in perfomance mode, and at the maximum speed of your processor.

在虚拟机上尝试此步骤 CPU 频率调整，会有类似如下显示。无法调整应为正常现象，似乎无重大后续影响。

2.1.2.4. Wi-Fi/Bluetooth

根据官方文档，可能需要关闭 Wi-Fi/Bluetooth，或移除对应的驱动，以解决某些问题

2.2. Get source code

官方综合文档（概述 EPC、eNB、UE的源码获取）：https://gitlab.eurecom.fr/oai/openairinterface5g/blob/master/doc/GET_SOURCES.md

对于 eNB UE，仓库为：https://gitlab.eurecom.fr/oai/openairinterface5g

2.2.1. Install git

sudo apt-get update
sudo apt-get install git

2.2.2. Clone the repository

cd ~
git clone https://gitlab.eurecom.fr/oai/openairinterface5g.git
# cd openairinterface5g/
# git checkout v1.1.0

2.3. Build

本质上通过使用 openairinterface5g/cmake_targets/build_oai 这个 Soft Modem Build Script 进行 build

这里同时编译 eNB 和 UE，也可分别编译。该脚本具有多种选项和参数设置，详见官方文档 https://gitlab.eurecom.fr/oai/openairinterface5g/blob/master/doc/BUILD.md

该脚本运行可能需要较长时间

cd ~/openairinterface5g/
source oaienv
cd cmake_targets/
./build_oai -I -w USRP --eNB --UE

结尾部分输出类似如下

至此基本的 eNB 和 UE build 完成，其他组件如 PHY Simulators （ https://gitlab.eurecom.fr/oai/openairinterface5g/-/wikis/OpenAirLTEPhySimul ）等参见官方文档

2.4. Run

官方文档 https://gitlab.eurecom.fr/oai/openairinterface5g/-/blob/master/doc/RUNMODEM.md

其中基本组件（eNB、UE）的运行见 https://gitlab.eurecom.fr/oai/openairinterface5g/-/blob/master/doc/BASIC_SIM.md

注意若要连接 EPC 先启动 EPC，使用虚拟机时，EPC 和 RAN 都要使用桥接网络模式，同时每次启动 IP 可能变化，每次都要修改配置文件有关网络参数

2.4.1. Run eNB

eNB basic simulator 有两种模式，连接 EPC（S1 mode） 或者不连接（noS1 mode）

2.4.1.1. Running in FDD mode with EPC

2.4.1.1.1. Configure network interface

根据实际网络配置设置，和 EPC 中对应的网络接口应处于同一网段，注意修改为实际网卡名，类似于 1.3.3.

sudo ifconfig enp0s5:e1c 192.168.247.10 up
sudo ifconfig enp0s5:e1u 192.168.248.10 up

2.4.1.1.2. Edit configuration file

在 MME 配置文件中 TAI_LIST 下找到一组 TAI 配置类似 {MCC="208" ; MNC="93"; TAC = "600"; }, ，如果有多组选择其中一组

编辑 eNB 配置文件

sudo gedit ~/openairinterface5g/ci-scripts/conf_files/lte-fdd-basic-sim.conf

修改 tracking_area_code 的值和 MME 中 TAC 一致

修改 plmn_list = ( { mcc = 208; mnc = 93; mnc_length = 2; } ); 中的 mcc 的值和 MME 中 MCC 一致，mnc 的值和 MME 中 MNC 一致，mnc_length 的值根据实际 mnc 值的长度确定

修改 downlink_frequency 的值为 2680000000

修改 N_RB_DL 的值选择带宽，从 (25, 50, 100) 中选择

替换 CI_MME_IP_ADDR 为 MME 配置中 m1c 虚拟网卡的 IP 地址，例如本文档中是 enp0s5:m1c 的 IP 地址 192.168.247.102，根据实际情况设置

以下几项根据运行 eNB 的本机配置情况修改，参考 2.4.1.1.1.

ENB_INTERFACE_NAME_FOR_S1_MME 的值修改为 "enp0s5:e1c"

ENB_IPV4_ADDRESS_FOR_S1_MME 的值修改为 "192.168.247.10"

ENB_INTERFACE_NAME_FOR_S1U 的值修改为 "enp0s5:e1u"

ENB_IPV4_ADDRESS_FOR_S1U 的值修改为 "192.168.248.10"

ENB_IPV4_ADDRESS_FOR_X2C 的值修改为 "192.168.247.10"

2.4.1.1.3. Starting up

cd ~/openairinterface5g/
source oaienv
cd cmake_targets/lte_build_oai/build

ENODEB=1 sudo -E ./lte-softmodem -O $OPENAIR_HOME/ci-scripts/conf_files/lte-fdd-basic-sim.conf --basicsim

2.4.1.2. Running in TDD mode without any EPC

cd ~/openairinterface5g/
source oaienv
cd cmake_targets/lte_build_oai/build

# NOTE: Here is TDD mode, change to corresponding configuration file to use.
# ENODEB=1 sudo -E ./lte-softmodem -O $OPENAIR_HOME/ci-scripts/conf_files/lte-fdd-basic-sim.conf --basicsim --noS1
ENODEB=1 sudo -E ./lte-softmodem -O $OPENAIR_HOME/ci-scripts/conf_files/lte-tdd-basic-sim.conf --basicsim --noS1

2.4.2. Run UE

2.4.2.1. Edit configuration file

在 HSS 的 Cassandra DB 中查询需要的参数，在运行 EPC 的计算机上查询

cqlsh
DESCRIBE TABLES
use vhss;
select imsi,key,opc,msisdn from users_imsi;
quit

选择一组数据，修改 UE 的配置文件

sudo gedit ~/openairinterface5g/openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf

MSIN 的值修改为 DB 中 imsi 的后10位

USIM_API_K 的值修改为 DB 中 key 的值

OPC 的值修改为 DB 中 opc 的值

MSISDN 的值修改为 DB 中 msisdn 的值

HPLMN 的值修改为 DB 中 imsi 的前5位

确认 OPLMN_LIST 中存在所使用的 HPLMN

2.4.2.2. Starting up

cd ~/openairinterface5g/
source oaienv

# Edit openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf
cd cmake_targets/lte_build_oai/build

../../nas_sim_tools/build/conf2uedata -c $OPENAIR_HOME/openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf -o .

sudo -E ./lte-uesoftmodem -C 2680000000 -r 25 --ue-rxgain 125 --basicsim [--noS1]

参数 -r 25 根据 eNB 的配置设置，N_RB_DL=25 使用 25，N_RB_DL=50 使用 50，N_RB_DL=100 使用 100

参数 -C 2680000000 是 downlink frequency，和 eNB 配置文件中的 downlink_frequency 值保持一致

--noS1 可选，如果要运行在 noS1 mode

注意：eNB 有 TDD 和 FDD 两种模式，每种有不同的配置文件，注意参数的对应。这里的参数配置示例是对应上面 FDD 模式的 eNB 配置的

2.4.3. Testing the data plane

S1 mode 即连接 EPC 的模式，noS1 mode 即不连接 EPC 的模式

2.4.3.1. In S1 mode

首先找到分配给 UE 的 IP 地址，在运行 UE 的计算机上运行

ifconfig oaitun_ue1

输出类似如下

oaitun_ue1 Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00  
          inet addr:12.1.1.2  P-t-P:12.1.1.2  Mask:255.0.0.0
...

其中 12.1.1.2 是 EPC 中 SPGW 分配给当前 UE 的 IP 地址

2.4.3.1.1. ping test

在运行 EPC 的计算机上运行

ping -I pdn -c 20 12.1.1.2
# ping -c 20 12.1.1.2

输出类似如下

在运行 UE 的计算机上运行

ping -I oaitun_ue1 -c 20 12.1.1.1

输出类似如下

2.4.3.1.2. iperf test

对于 DL iperf test

在运行 UE 的计算机上运行

iperf -B 12.1.1.2 -u -s -i 1 -fm -p 5001

在运行 EPC 的计算机上运行

iperf -c 12.1.1.2 -u -t 30 -b 10M -i 1 -fm -B 12.1.1.1 -p 5001

对于 UL iperf test

在运行 EPC 的计算机上运行

iperf -B 12.1.1.1 -u -s -i 1 -fm -p 5001

在运行 UE 的计算机上运行

iperf -c 12.1.1.1 -u -t 30 -b 2M -i 1 -fm -B 12.1.1.2 -p 5001

2.4.3.2. In noS1 mode

IP 地址是固定的，但是同样可以通过如下命令查看

在运行 UE 的计算机上运行

ifconfig oaitun_ue1

在运行 eNB 的计算机上运行

ifconfig oaitun_enb1

2.4.3.2.1. ping test

ping -I oaitun_ue1 -c 20 10.0.1.1
ping -I oaitun_enb1 -c 20 10.0.1.2

2.4.3.2.2. iperf test

iperf -B 10.0.1.2 -u -s -i 1 -fm
iperf -c 10.0.1.2 -u -b 1.00M -t 30 -i 1 -fm -B 10.0.1.1
