Setup Example

Setup used to test the application with open5GS:

I used two VMs:

• VM1 with the application
• VM2 with the open5GS Core

Used config files:

Note: I only show the config files I changed.

mme.yaml

logger:
    file: /var/log/open5gs/mme.log

mme:
    freeDiameter: /etc/freeDiameter/mme.conf

        - ::1

sgwu.yaml

logger:
    file: /var/log/open5gs/sgwu.log

sgwu:
    pfcp:
      - addr: 127.0.0.6
    gtpu:
      - addr: 172.16.168.131
      - addr: 127.0.0.6

How I did run the application in VM1:

root@ubuntu:/home/fabricio# python3 eNB_LOCAL.py -i 172.16.168.130 -m 172.16.168.131 -u 0 -o 20893 -g 172.16.168.131

I was using a USIM with different MCC/MNC (90170).

Options used:

• Option 15 for eNB Setup
• Option 20 for the Attach procedure
• Option 50 to enable GTP-U (did some pings to 1.1.1.1)
• Option 21 to Detach
