Installation

1. Install FlexRIC and dependencies

Install Swig

follow this link: https://swig.org/svn.html

git clone https://github.com/swig/swig.git
cd swig
./autogen.sh
./configure --prefix=/usr/
make
make install (if not work use sudo make install)

for the first time running ./autogen.sh, with no alocal

sudo apt-get install autotools-dev
sudo apt-get install automake

for the first time running ./configure --prefix=/usr/ and error

## ./configure --prefix
# configure: error: no acceptable C compiler found in $PATH
>> sudo apt install build-essential

# Cannot find pcre2-config script from PCRE2 (Perl Compatible Regular Expressions)
>> sudo apt install libpcre2-dev

# WARNING: 'bison' is missing on your system.
>> sudo apt install bison

if you cannot make

• maybe your folder contain 'spacebar' in the name
• or need to install autoconf, automake, aclocal

Installl dependencies

$ sudo apt install libsctp-dev python3.8 cmake-curses-gui libpcre2-dev python3-dev

Install FlexRIC

clone the branch 'e2ap-v2', and download the patch from the main link updated 120424, clone from branch br-flexric

git clone https://gitlab.eurecom.fr/mosaic5g/flexric.git
cd flexric
git checkout br-flexric
mkdir build
cd build
cmake ../

# change gcc and g++ version before proceed below
make
sudo make install

before make you need to change gcc and g++ version to 10

change gcc and g++ version to 10

follow this link: https://linuxconfig.org/how-to-switch-between-multiple-gcc-and-g-compiler-versions-on-ubuntu-22-04-lts-jammy-jellyfish

Install GCC and G++ compiler

sudo apt update
sudo apt install build-essential
sudo apt -y install gcc-10 g++-10

Update alternative, then compile the version 10, and check if the version selected correctly

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 10
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-10 10
sudo update-alternatives --config gcc
sudo update-alternatives --config g++

and check gcc and g++ version

gcc --version
gcc (Ubuntu 10.5.0-1ubuntu1~22.04) 10.5.0

g++ --version
g++ (Ubuntu 10.5.0-1ubuntu1~22.04) 10.5.0

after that, run make command

make
sudo make install

Install ccache (for fast re-compilation)

before make any code with gcc, g++
installation following this link: https://askubuntu.com/questions/470545/how-do-i-set-up-ccache

# Install package
sudo apt install -y ccache

# Update symlinks
sudo /usr/sbin/update-ccache-symlinks

# Prepend ccache into the PATH
echo 'export PATH="/usr/lib/ccache:$PATH"' | tee -a ~/.bashrc

# Source bashrc to test the new PATH
source ~/.bashrc && echo $PATH

path will looks like this

/usr/lib/ccache/:/usr/lib/ccache/:/home/chatchamon/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin

and test successful of ccache

>> which g++ gcc
/usr/lib/ccache/gcc
/usr/lib/ccache/g++

2. ZeroMQ

not install from source (https://github.com/zeromq/libzmq/issues/4390)
but install from package: $ sudo apt-get install libzmq3-dev

git clone https://github.com/zeromq/czmq.git
cd czmq
./autogen.sh
./configure
make
sudo make install
sudo ldconfig

3. srsRAN_Project

from this link: https://github.com/srsran/srsRAN_Project/issues/158

install dependencies as we cannot install zeromq from source, then install srsRAN_Project, and finish make result look like (finish)

$ sudo apt install cmake make pkg-config libfftw3-dev libmbedtls-dev libsctp-dev libyaml-cpp-dev libgtest-dev


$ git clone https://github.com/srsran/srsRAN_Project.git
$ cd srsRAN_Project
$ mkdir build
$ cd build
$ cmake ../ -DENABLE_EXPORT=ON -DENABLE_ZEROMQ=ON -DAUTO_DETECT_ISA=OFF
$ make -j`nproc`

also during cmake it show zeromq disable by default

-- Checking for module 'ZeroMQ'
--   No package 'ZeroMQ' found
-- Found libZEROMQ: /usr/include, /usr/lib/x86_64-linux-gnu/libzmq.so

4. srsRAN_4G

install dependencies from this link: https://docs.srsran.com/projects/4g/en/latest/general/source/1_installation.html

sudo apt-get install build-essential cmake libfftw3-dev libmbedtls-dev libboost-program-options-dev libconfig++-dev libsctp-dev

make the czmq again

git clone https://github.com/zeromq/czmq.git
cd czmq
./autogen.sh
./configure
make
sudo make install
sudo ldconfig

then install srsRAN_4G through zeroMQ, from this link: https://docs.srsran.com/projects/4g/en/latest/app_notes/source/zeromq/source/index.html

git clone https://github.com/srsRAN/srsRAN_4G.git
cd srsRAN_4G
mkdir build
cd build
cmake ../
make

during cmake, it should show that zeromq should disable by default

-- Checking for module 'ZeroMQ'
--   No package 'ZeroMQ' found
-- Found libZEROMQ: /usr/include, /usr/lib/x86_64-linux-gnu/libzmq.so

in case zeromq link like below, you need to make the czmq again, before delete and install srsRAN_4G again to link zeromq with them

FINDING ZEROMQ.
-- Found Boost: /usr/lib/x86_64-linux-gnu/cmake/Boost-1.74.0/BoostConfig.cmake (found suitable version "1.74.0", minimum required is "1.35") found components: program_options

5. Config gNB and UE

5.1 for nearRT-RIC and xApp

download gnb and ue config files from https://docs.srsran.com/projects/project/en/latest/tutorials/source/flexric/source/index.html
the gNB change is Enable E2 agents in all DUs and enable E2SM_KPM service module:

e2:
  enable_du_e2: true                # Enable DU E2 agent (one for each DU instance)
  e2sm_kpm_enabled: true            # Enable KPM service module

and Enable E2AP packet captures and set the name of the output pcap file:

pcap:
  e2ap_enable: true                 # Set to true to enable E2AP PCAPs.
  e2ap_filename: /tmp/gnb_e2ap.pcap # Path where the E2AP PCAP is stored.

5.2 for USRP 210

Running the network

in the following order

1. open5GS
2. NearRT-RIC
3. gNB
4. UE
5. start IP traffic (e.g. ping)
6. xApp from the list, we will open 6 terminal window for each of them

1. open5GS core (docker version)

from srsRAN_Project/docker

cd ./srsRAN_Project/docker
sudo docker-compose up --build 5gc

in case it cannot run try

sudo docker compose up --build 5gc

from this issue: https://github.com/srsran/srsRAN_Project/issues/198, we need to comment line 79 COPY subscriver_db.cs[v] . in the srsRAN_Project/docker/open5gs/Dockerfile. and the issue will be solved

in case of issue, following this simple troubleshooting https://open5gs.org/open5gs/docs/troubleshoot/01-simple-issues/.

• replace <command> with stop, then do it again with restart

>> sudo -i
$ systemctl <command> open5gs-mmed.service
$ systemctl <command> open5gs-sgwcd.service
$ systemctl <command> open5gs-smfd.service
$ systemctl <command> open5gs-amfd.service
$ systemctl <command> open5gs-sgwud.service
$ systemctl <command> open5gs-upfd.service
$ systemctl <command> open5gs-hssd.service

$ systemctl <command> open5gs-pcfd.service
$ systemctl <command> open5gs-nssfd.service
$ systemctl <command> open5gs-bsfd.service
$ systemctl <command> open5gs-udrd.service
>> exit

However, if the issue state the replicate of docker, just delete the docker, and sudo docker compose again

3. gNB

start with CPU performance mode

• The CPU governor of the PC should be set to performance mode to allow for maximum compute power and throughput. Config for Ubuntu

echo "performance" | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

• then config in the srsran script

>> cd o-ran-e2-kpm/czmq/srsRAN_Project
>> sudo ./scripts/srsran_performance 

Would you like to set the CPU governor to performance: [Y/n]: y
Scaling governor set to performance
Would you like to disable KMS polling: [Y/n]: y
Disabled DRM KMS polling
Would you like to tweak the network buffer sizes: [Y/n]: y
net.core.wmem_max = 33554432
net.core.rmem_max = 33554432
net.core.wmem_default = 33554432
net.core.rmem_default = 33554432
Tweaked network buffer sizes

Then continue with config files and run the gNB

• download config file (gNB.conf): https://docs.srsran.com/projects/project/en/latest/tutorials/source/flexric/source/index.html
  
• put the file in folder ./srsRAN_Project/build/apps/gnb
• run command sudo ./gnb -c gnb_zmq.yaml

oem@oem-ThinkPad-L14-Gen-2:~/work/srsRAN_Project/build/apps/gnb$ sudo ./gnb -c gnb_zmq.yaml

• in case socket is in used like below, kill it with

sudo netstat -plten
sudo kill -9 <port number>

4. srsUE

• download config file (ue.conf): https://docs.srsran.com/projects/project/en/latest/tutorials/source/flexric/source/index.html
  
• put the file in folder ./srsRAN_4G/build/srsue/src

before run the command

• add ue1 sudo ip netns add ue1
• check ue sudo ip netns list or else it will show Failed to setup/configure GW interface

then

• run command sudo ./srsue ./ue_zmq.conf

oem@oem-ThinkPad-L14-Gen-2:~/work/srsRAN_4G/build/srsue/src$ sudo ./srsue ./ue_zmq.conf

It is clear that the connection has been made successfully once the UE has been assigned an IP, this is seen in PDU Session Establishment successful. IP: 10.45.1.2. The NR connection is then confirmed with the RRC NR reconfiguration successful. message.

if PDU session not create like Failed to setup/configure GW interface could be from incomplete make/make install. So need to repeat the installation

Test IP Traffic with Ping. The ping test will run alongside with the next test (xApp). Wihtout ping running, RSRP metrics receive from xapp_kpm_moni will result as RSRP = 0.

we add ue1 from link: https://docs.srsran.com/projects/project/en/latest/tutorials/source/srsUE/source/index.html#srsue-appnote at section

• add ue1 sudo ip netns add ue1
• check ue sudo ip netns list

then we test ping.

• open another terminal to ./srsRAN_4G/build/srsue/src
• test ping sudo ip netns exec ue1 ping -i 0.1 10.45.1.1

oem@oem-ThinkPad-L14-Gen-2:~/work/srsRAN_4G/build/srsue/src$ sudo ip netns exec ue1 ping -i 0.1 10.45.1.1
