One core. Two planes.
Control sets up the path. The UPF carries packets; IMS connects voice calls.
Select a phone to inspect its registration and data session.
Power on UE1 to watch it join the network, then establish its data session.
Automotive factory · 70 UE devices
20 AGVs deliver parts to 50 assembly robots through the core.
Start with -Factory or --factory to enable the fleet, two factory gNBs, and the logistics platform.
Web mobiles · independent phones
Add up to ten mobiles, connect them to a gNB, and exchange messages between their own inboxes.
Use Add mobile, then open each phone in its own tab. Connect both and choose the other phone under Conversation to send SMS-style messages. Added mobiles also appear in the SMS panel below.
UE6 mobility · two Docker gNBs
One active data session moves between cell 1 and cell 2.
Prepare UE6, then choose a handover. Each move targets the other gNB.
Real XnAP/SCTP and NGAP signalling · real AMF, SMF and UPF path update · simulated radio.
UDP echoes every 20 ms measure loss and gaps. One TCP connection runs before, during and after the move.
Download measured samples ↓TS 23.502 §4.9.1.2.2 (Xn) and §4.9.1.3.2–3 (N2), same AMF and UPF. No Xn-U forwarding; any interruption is measured. Radio uses the experimental UERANSIM mobility extension.
PDU session establishment · new UE6
Register a new phone → establish its data session → verify packet forwarding
UE6 joins with no automatic data session. Watch NAS, SBI, PFCP and NGAP in Latest interactions as it requests IPv4 on internet, slice SST 1.
Choose Register new UE6 to begin. Repeat step 1 to reset this demo.
IMSI 001010000000006 · configured tunnel 10.45.0.7
