Hi I am using latest version of free5gc and UERANSIM on every machine and to resolve this issue, i also flush mongo database and restart all network functions but no luck :-(
Hi @ishanshahnio
I updated my environment with latest free5GC and tried it, and I was able to ping as expected without SMF crashing. In addition, as I wrote in the repository, I changed from v3.2.1 to the main branch and built it.
Also, nrfcfg.yaml
required the following changes:
nrfcfg.yaml: version: 1.0.1 --> 1.0.2
According to the error log, SMF seems to be accessing an illegal memory address, but I don't know why.
Hi @s5uishida
Thanks for Reply. I will check and let you know.
Just for curiosity, did you get a chance to work on multiUPF that total 3 UPF (Anchor UPF, UPF-1 and UPF-2) that default path is Anchor UPF -> UPF1 and traffic influence (Npcf) divert data path from UPF1 to UPF2 and final path will be Anchor UPF -> UPF2.
Hi @s5uishida, Issue resolved.
Issue was SBA interface binding in UPF. I used localhost IP Addresses scheme in UPF, so SMF not create N4 pfcp session binding.
Hi @s5uishida,
Your GitHub repository is very informative, useful and learning for implementation of 5G core.
I want to achieve one scenario that 2 UPF are connected to branching UPF. Scenario is as below:
I much appreciate if you achieved above scenario in your lab using free5gc or any other freeware and opensource 5GC.
Hi @ishanshahnio
I wrote another ULCL configuration example as follows.
https://github.com/s5uishida/free5gc_ueransim_ulcl_2_sample_config
Also, I'm not using Npcf_policyauthorization
.
Thanks @s5uishida, let me try this scenario in my local lab and will update you on this soon.
Hi @s5uishida,
first of all your GitHub repository is very informative and i want to achieve this scenario with ULCL.
I have separate virtual machines for UERANSIM, I-UPF, PSAUPF1 and Free5gc.
I start I-UPF, PSAUPF1, Free5gc and last I ran Gnb and UE device.
once I start UE, first session established and later SMF crashed on free5gc machine. could you please help me to solve this error.
