UE detachment using the core #362

Open cezeno2s opened 3 years ago

cezeno2s commented 3 years ago

Hello @aligungr, I am working with open5gs and UERANSIM simulator in setting up a full stack 5G network architecture on my thesis and would like to detach my UE(s) using the core side to achieve this just like network operators would in real life scenarios in contrast to detaching from the UE side. Please is there a way I can achieve this from the core? I would appreciate any input on this issue.

Kind regards, David.

Hi David

AMF sends "Network-initiated de-registration request" to the UE in case of the core network wants the UE to detach. However I don't fully know in which cases Open5GS sends De-registration Request to the UE.

Perhaps it's better to open an issue or discussion in Open5GS side, however Sukchan may be unavailable and too busy.

And also you can check 3GPP specifications especially 23.501, 23.502, 24.501. Reading the source code of Open5GS may be helpful as well.

Best
