Hello @virendra, can you please provide the log information, the version of free5GC, the version of UERANSIM, and the installation environment? Thank you.

Hi @wilson30139 I am using free5gc 3.3.0 and UERANSIM 3.2.6 for simulation. and using VM for all this.

Hello @virendra, thank you for the quick reply. What is your problem in the video? The problem can be running free5GC, running UERANSIM, packet transmission, etc.

#5

Unable to start upfs after configurations. If you are then Can we connect over meet or zoom to look into this.

Hello @virendra, I think you can try to execute sudo bin/upf under the free5GC directory. In addition, you can reter to this link. I think it should be helpful to you.

Hello @virendra. First, you terminate ./run.sh in the free5GC-CP and build/nr-gnb -c config/free5gc-gnb.yaml in the UERANSIM. Second, you try to execute ./run.sh in the free5GC-CP again. Then you execute build/nr-gnb -c config/free5gc-gnb.yaml in the UERANSIM. See if the problem can be solved.

Did it. still getting same error

#12

Hello @virendra, you try to terminate:

  • build nr-gnb -c config/free5gc-gnb.yaml in the UERANSIM
  • ./run.sh in the free5GC-CP
  • sudo bin/upf in the I-UPF, PSA-UPF1 and PSA-UPF2

Then you execute ./force_kill.sh in the free5GC-CP. You execute these commands again:

  • sudo bin/upf in the I-UPF, PSA-UPF1 and PSA-UPF2
  • ./run.sh in the free5GC-CP
  • build nr-gnb -c config/free5gc-gnb.yaml in the UERANSIM

See if the problem can be solved.

#13

tried but it didn’t solved problem. still getting same error

#14

Hello @virendra, try it a few more times and see if the problem can be solved. If it really doesn’t solve in the end, I suggest you execute these commands:

  • remove the gtp5g directory
  • git clone -b v0.8.2 https://github.com/free5gc/gtp5g.git
  • cd gtp5g
  • make
  • sudo make install

See if the problem can be solved.
