Last year I wrote about a 5G Americas whitepaper that describes how 3GPP has standardized the 5G core in a way that lends itself for cloud based implementation. In short, that means that control plane functions are split into microservices, deployed on bare metal clusters in containers and managed with Kubernetes. So far the theory. … Continue reading The Cloud Based 5GC – From Theory To Practice

Ever since GPRS came around the corner one and a half decades ago there’s been this concept of international roaming with ‘local breakout’ in which IP packets of roaming subscribers are sent directly to the Internet from the visited network. Sounds nice but in practice, it’s not really used. Instead, the current approach is referred … Continue reading The 5G Core Network (5GC) – Part 3 – Local Breakout

In part one of this mini-series on the 5G core network I’ve taken a look at some of the new concepts and how the network entities there with their new names map to what we already know from the EPC, i.e. the 4G core network. Now that this is done let’s have a look at … Continue reading The 5G Core Network (5GC) – Part 2 – Identifiers

When network operators are ready to go beyond 5G EN-DC, which basically means that a mobile device camps on a 4G cell and a 5G cell is added for additional speed, they require a 5G core network. To find out more about the 5GC, a good starting points are 3GPP TS 23.501 (System Architecture – … Continue reading The 5G Core Network (5GC) – Part 1 – Network Entities

It’s been a while since I installed a headless Raspberry Pi from scratch with a desktop GUI to be accessed over the network. In the ‘early days’ of the Pi this used to be very simple: Get an image file from the Raspbian website, use ‘dd’ on Linux to copy the image to an SD … Continue reading Raspberry Pi With Remote Screen Sharing – A Quick Installation Guide

I’m running Ubuntu 20.04 on my notebook, which by now is around 2 years old. This means that some programs are of the same age, as newer versions are not included in the repository. For most programs, that is just fine for me. Some programs are evolving quickly, however, and when it comes to Wireshark, … Continue reading Compiling Wireshark on Ubuntu

Now that the non-Standalone (NSA) flavor of 5G has been pretty much established around the globe, it is likely that more focus is put on the 5G standalone (SA) flavor of the technology. In effect that means two things: Instead of using LTE as an anchor for a 5G air interface connection, 5G can stand … Continue reading Voice over NR Whitepapers

In the previous post on the topic I wrote about the three eras of telecom infrastructure hardware. As we are now entering the third area, there are not only whitepapers written about how everything from the radio network to the mobile core can be but into containers, but there are also demo videos of such … Continue reading An ‘Everything in Containers’ LTE and 5G Demo

As you might have noticed on the blog, I’ve been doing a lot of hands-on exploration these days of bare metal hardware, virtual machines, containers and orchestration (e.g. Kubernetes). My motivation behind this is twofold. For one thing, I like to evolve my private cloud. Current status: 25 containers are now running in my private … Continue reading The Three Eras Of Telecom Infrastructure Hardware
