I’m getting the same ‘has no pre-config route’ error along with a few AMF errors and a somewhat similar go panic in my free5gc log. The same process worked in v3.0.4. I didn’t add all the logs as this can probably be figured out with the logs you provided; but I think my error is a little different.

There was one error higher in the log:

And here is the panic:

Hi,
I have the same problem. The panic error can be solved by checking the mongo DB. The webconsole is creating not all required information.

In my case I removed the following entry by hand and added it again:

use free5gc
db.policyData.ues.smData.remove({})
db.policyData.ues.smData.insert({"smPolicySnssaiData" : { "01112233" : { "smPolicyDnnData" : { "internet" : { "dnn" : "internet" }, "ims" : { "dnn" : "ims" } }, "snssai" : { "sst" : 1, "sd" : "112233" } } }, "ueId" : "imsi-001010000000011" })

after that, the panic error was gone. Reason: the webconsole was only creating one smPolicyDnnData for internet but not for ims.

I debugged it a little bit further. It seems like the UPF is not yet involved and it crashes before the first PFCP message is send from the SMF to the UPF.

@free5GC any ideas on that?

best,
Ralf

#4

Update:

I found out where the ActivateTunnelAndPDR error is coming from:
in smf/context/upf.go the function IP(…) starting in line 105 is causing the problem. (smf/upf.go at 04c01ec5dd4e0e69342e9047a1d37442d88d9904 · free5gc/smf · GitHub)

Only PDUSessionTypeIPv4 and PDUSessionTypeIPv6 are supported here, however, in my case it was PDUSessionTypeIPv4IPv6. I just added an additional if statement catching this case and returning the IPv4 address.

best,
Ralf

hi,Can’t the user’s session data be added on the webui? I added on the webui here, but the session data that reminds the user is not in the UDR, please explain in detail how to add it in the background, thank you very much!

#5

thanks a lot Ralf, this is helpful.
FYi that i don’t ue webgui on free5gc, I only use mongo db. Do I still need to delete the smdata entry and re-add it?
Also when I saw this error, I don’t have a data network (server) connected to my UPF yet. Do you have this DN server connected to your UPF when you saw this error on your setup?
BTW, my UE is not real one, it’s a gnb/ue simulator call gnbsim (GitHub - hhorai/gnbsim: gnbsim is a 5G SA gNB/UE simulator for testing 5G System.), this tool use free5gc (v304 though, not latest v305), and this gnbsim use below free5gc setup (focus is the http server part) as below:

image1830×1306 144 KB

Again, what is your UPF-DN (N6) setup when you see your error.

#6

fyi that I don’t have this issue on v3.0.4 free5gc.

#7

Hi,
I had no N6 / data network setting in free5gc configured. Even after fixing the problem I had no data network configured.

regarding mongoDB: the free5gc v3.0.4 entries are not working for version 3.0.5 for me. It was required for me to add them slightly differently. I added them over the html gui and fixed some values(i.e. the smData table).

best,
Ralf
