My first 5G Core: Open5Gs and UERANSIM

Note: As this space develops so quickly I’ve refreshed the original post from November 2021 in March 2021 with updated instructions. While 5G SA devices are still in their early stages, and 5G RAN hardware / gNodeBs are hard to come by, so today we’ll cover using UERANSIM to simulate UEs and 5G RAN, to […]

Open5GS Python Library / API

A while ago I wrote a Python library for interfacing Open5GS HSS to Python. The Open5GS HSS uses a MongoDB backend, so the library is just running formatted Mongo queries. You can create, edit and delete subscribers in the HSS, along with modifying any parameters you can from the WebUI. Take a look: https://github.com/open5gs/open5gs/tree/master/misc/db/python

Open5Gs- Python HSS Interface

Note: NextEPC the Open Source project rebranded as Open5Gs in 2019 due to a naming issue. The remaining software called NextEPC is a branch of an old version of Open5Gs. This post was written before the rebranding. I’ve been working for some time on Private LTE networks, the packet core I’m using is NextEPC, it’s […]
