I Need Help Searching for Open Source Software Stack for 3G

[serttasbugrahan]

I am looking for open source software stack for 3G, like OpenAirInterface for 5G or Osmocom for 2G. (Osmocom has partial support for 3G)

Kindly asking you to forward me to the right source who may know.

Thank you for your time and kind attention.

Best Regards,
