When ./nr-ue is running, how can I update the configuration information of UE #285

I noticed that Feature Set mentioned UERANSIM implemented Generic UE Configuration Update, so When ./nr-ue is running, how can I update the configuration information of UE? In fact, when UE is running, I want to switch slices, so I need to update the UE configuration to re-register.

Generic UE Configuration Update is triggered by AMF, and UE is not involved in the initiation of this procedure. Therefore you need to trigger the procedure using the core network. See TS 24.501 (Section 5.4.4, page 125). And by the way, please note that the Generic UE Configuration Update is partially implemented, i.e some cases does not handled yet in UE side.

@aligungr Thanks for the answer. I'll take a look at the specification document.
