How to Activate Paging

Q/A

#1

Expected:
Trigger paging procedure when Ping an idle-UE.

What I’ve try:
1.Run Free5GC and UERANSIM gnb/ue;
2.Establish a uesimtun0 and success to ping google via uesimtun0;
3.Kill UERANSIM gnb and restart it, to make UE idle;
4.ping idle-UE 10.60.0.1(with gnb setup but no UE connected now).
It seems nothing happen to SMF, I can grab ICMP in UPF but nothing PAGING trigger.

How to trigger PAGING successfully besides steps above?

Not sure if killing gNB is a valid way to test that, IMO you should ask UERANSIM’s team how to trigger UE idle.

Here’s free5gc’s paging test https://github.com/free5gc/free5gc/blob/e104d468c93571484bdde21cd1442385804f4db6/test/registration_test.go
And by the way, this is the only test that fails for me on my environment(kernel 5.15.49-1-MANJARO) and passes on ubuntu. So make sure you follow free5gc rules for OS.
