[Discussion] Identify on which UE to trigger a rrcRelease

[elrandira]

Hi @aligungr,

the gnb part of ueRANSIM allows us to trigger a rrcRelease on a simulated UE but how do we know which UE is which?

Currently when I simulate several UEs, I can identify them in the UE part of ueRANSIM by their IMSI but on the gNodeb side I can't do such.

ue-list in the gnb returns me this:

$ ue-list
- ue-id: 1
  ran-ngap-id: 1
  amf-ngap-id: 226

whereas on the UE side I can get these info:

$ info
supi: imsi-208900000000006
hplmn: 208/90

I was expecting maybe to find the ran-ngap-id but that might not be 3GPP compliant? How can we identify the relation between a UE and its gNB?

Thanks for your help
