NextMN-UE Lite

NextMN-UE Lite is an experimental User Equipment simulator designed to be used along with NextMN-gNB Lite and NextMN-CP Lite to mimic from an UPF point-of-view a 5G & beyond Control Plane and a RAN.

3GPP N1/N2 interfaces are not (and will not be) implemented, and Control Plane is minimalistic on purpose.

This allow to test N3 and N4 interfaces of an UPF, and in particular to test handover procedures.

If you don't need to use handover procedures, consider using UERANSIM along with a real Control Plane (e.g. free5GC's NFs) instead.

Getting started

Build dependencies

• golang
• make (optional)

Runtime dependencies

• iproute2
• iptables

Build and install

Simply run make build and make install.

Docker

If you plan using NextMN-UE Lite with Docker:

• The container required the NET_ADMIN capability;
• The tun interface (/dev/net/tun) must be available in the container.

This can be done in docker-compose.yaml by defining the following for the service:

cap_add:
    - NET_ADMIN
devices:
    - "/dev/net/tun"
