Editing gNB and UE Configuration

You can edit the configuration files for gNB and UE by accessing their respective Docker containers. Follow these steps:

Steps to Edit Configuration

1. Enter the container: Use the following command to access the gNB or UE container:

   sudo docker exec -it <container_name> bash
   

For gNB:

• Open and edit the gnb.yml file.
• Adjust the location of the gNB by modifying the phyLocation parameter in the YAML files.
• Configure the following parameters for Wi-Fi settings:
  • wifi
  • sessionIP
  • nextHop
  • UeInterface
  • nextHopInterface

For UE:

• Open and edit the ue.yml file.
• Add all the IP addresses of gNBs that the UE might connect with in the gnbSearchList parameter.
• Define an array of (x, y, z) coordinates for the phyLocation parameter, as currently done.
• Ensure the movement pattern is set to linear.
• Specify the velocity of the UE in meters per second (m/s).
• Set wifi to true when using Wi-Fi.
• Declare the following additional parameters:
  • staticIP: Specifies the IP address of the UE.
  • Interface: Specifies the interface through which the UE is connected.

Note: Wi-Fi configuration is applicable only when there is no 5G core network.

Starting gNB and UEs

In different terminal tabs or windows:

gNB

$ cd scripts/
$ ./start-gnb.sh

UE 1

$ cd scripts/
$ ./start-ue1.sh

UE 2

$ cd scripts/
$ ./start-ue2.sh

Using SSH for UE's

Open a new terminal tab or window and execute the following:

$ ssh -X root@clab-ueransim-ue1

(for UE 1)

$ ssh -X root@clab-ueransim-ue2

(for UE 2)

Password is gprsumts.

Destroying the scenario

$ cd scripts/
$ ./destroy.sh
