Can we please have the pcap file?
We will like to know your docker environmental architecture, likewise where the RAN and UE is mounted (For instance, simulator or else where?) on?

#3

RAN and UE runs as a simulator. can you tel me what do you mean by hows your docker env and architecture?

#5

RAN and UE is also in the container or not. Is it use the same compose file as CN or not. If RAN wants to access to CN, will it go through NAT or it can directly route to CN. etc.

Briefly to says that it is better if you can draw your architecture of the docker env setup.

#6

RAN and UE are not in the container. It runs as on a separate host. We have added routes from another host (where RAN and UE will be running) to reach the CN.

#7

How’s your UPF’s config file looks like?

There is no PFCP Association Setup Response, is your UPF running successfully?

#15

Kindly ignore the previous wireshark captures on pfcp.There were some warnings in pcf entity when I captures those logs.
After restarting my system I freshly took wireshark captures. I didnot notice any pfcp messages.
Im attaching entire terminal logs and fresh wireshark captures. It doesnot contain any pfcp messages even after applying filters.

I found the error:

http2: server connection error from 10.100.200.9:44714: connection error: PROTOCOL_ERROR

Try to set all of your sbi to https, will it work?

#17

Do you mean scheme has to be changed to https in all the config files?
