Invalid S-NSSAI
Standardized S-NSSAI (SST= 1 to 127) has only SST and no SD value (TS 23.501, R16.0.0., 5.15.2.1).
Hence S-NSSAI with SST, SD = 1, 010203 in sample config file is invalid actually.
How to set OPc and Key ?
In config file there is no field for OPc and Key.
Will you please tell us how it can be configured to test with different core networks ?
Servings network name is hardcoded
Servings network name is hard-coded with MCC, MNC value.
It will be good if MCC, MNC from config is used.

Hardcoded values
Hello
I have seen that following values are hardcoded in the message, and it will be great if we can configure them in the config file.
- TAC in the UplinkNASTransport(RegistrationRequest)
- SNSSAI, DNN in PDUSessionEstablishment request
- Procedure transaction id, it should be > =1 in PDUSessionEstablishment request
go.mod checksum mismatch
I'm suddenly getting "security error" regarding mismatched checksum in go.mod.

Was there a force-push in one of the dependencies?
Remove dependency from the `amf` module
Currently, the gnbsim module has the amf module as its dependency because of the use of one struct (PlmnSupportItem), one function (NewPlmnSupportItem) and two variables (MaxNumOfServedGuamiList, MaxNumOfPLMNs) in gnodeb/context/gnbamf.go and gnodeb/worker/gnbamfworker/handler.go. The gnsim should not depend on the amf module
gNBSim should support executing subscribers call flow in parallel
AS of today, gNBSim generates call flow events for all the subscribers within profile in sequential manner.
We wish to support option in the profile to support multiple subscriber call model execution in parallel.
gNBSim crashes upon receiving NAS Configuration update command
After UE registration, if the core network sends a NAS PDU with Message type: Configuration update command (0x54), gNBSim process crashes with a fatal error.
Packet capture and gNBSim logs: gnbsim54.zip
The offending packet was generated by Open5GCore and looks like this:

context.GetSimUe - fatal error: concurrent map read and map write
I have a sighting of a crash in simue/context package when a large number of profiles are starting/running in parallel.
This error only occurred once and does not reproduce reliably.
Nevertheless, I'm reporting it here so that this race condition can be reviewed.

According to ETSI TS 123.502 V16.7.0 section 4.2.3.2:
In the case of NG-RAN:
The AN parameters include 5G-S-TMSI, Selected PLMN ID, Establishment cause and may also include NSSAI information
The message generated by gNBSim (frame 41 in the packet sample) is:

Need more documentation to use gnbsim
First, It is great project. But, I do not see enough documentation. I am eager to add doc contributions. Can admin enable wiki for this project.
Multiple QoS flows
Hi! I would like to know if gnbsim is prepared to handle multiple QoS flows in a single PDU session. Thanks in advance.
