Navigate to the directory containing the docker-compose.yaml file and use the command:
sudo docker-compose up -d
Before starting the UERANSIM UE simulation, we need to register our subscriber to the 5G core. To do this we can log in to the Open5Gs webui at localhost:3000/ with username admin and password 1423. Alterinativelly, we can use the CLI tool to register the users directly from the mongodb container.
The following open5gs-dbctl.sh script can be executed inside the mongodb container, to add a subscriber without having access to the open5gs webui:
Gain shell access to the mongodb container:
sudo docker exec -it mongodb bash
Navigate to the scripts directory:
cd scripts/
Execute the script with the following arguments: imsi, key, opc
./open5gs-dbctl.sh add <imsi> <key> <opc>
In our case, it should be:
./open5gs-dbctl.sh add 208930000000001 0C0A34601D4F07677303652C0462535B 63bfa50ee6523365ff14c1f45f88737d
the output of this command should be something like:
root@43ac84dc385c:/# ./open5gs-dbctl.sh add 208930000000001 0C0A34601D4F07677303652C0462535B 63bfa50ee6523365ff14c1f45f88737d

After registering the UE with the command above, or on the Open5GS webui, create a new UE instance:
sudo docker exec -it ueransim-ue-0 bash
./nr-ue -c ./oai-ue.yaml
You don't need to do the same for the gNB, as it is already done in the docker-compose.yaml file.
To capture all 5G core traffic, use the following filter:
ip.src == 172.21.0.111 || ip.dst == 172.21.0.111 || ip.src == 172.21.0.101 || ip.dst == 172.21.0.101 || ip.src == 172.21.0.103 || ip.dst == 172.21.0.103 || ip.src == 172.21.0.100 || ip.dst == 172.21.0.100 || ip.src == 172.21.0.104 || ip.dst == 172.21.0.104 || ip.src == 172.21.0.105 || ip.dst == 172.21.0.105 || ip.src == 172.21.0.114 || ip.dst == 172.21.0.114 || ip.src == 172.21.0.106 || ip.dst == 172.21.0.106 || ip.src == 172.21.0.107 || ip.dst == 172.21.0.107 || ip.src == 172.21.0.120 || ip.dst == 172.21.0.120 || ip.src == 172.21.0.108 || ip.dst == 172.21.0.108 || ip.src == 172.21.0.109 || ip.dst == 172.21.0.109 || ip.src == 172.21.0.110 || ip.dst == 172.21.0.110 || ip.src == 172.21.0.112 || ip.dst == 10.45.0.2
