About This Site

The 5GC Textbook is an online learning resource that aims to let you study the 3GPP-compliant 5G Core Network systematically, from beginner through to a practical, working level. Rather than being a summary of the specifications, it is structured with the top priority of being something you can "read and actually understand".

About How It Is Produced

Each page of this site is produced by using AI to create a rough draft, and then adding to and revising it based on the author's own hands-on experience. AI-generated content is not published as-is; the author reviews and adjusts the content from the perspectives of technical accuracy and real-world practice.

Even so, this process does not guarantee the accuracy or completeness of the content. If you notice any errors, it would be a great help if you could point them out to the contact address below.

About the Author

I have worked at a certain foreign-affiliated telecom vendor for more than 10 years. While feeling somewhat out of place in a corner of the huge force that is the RAN, I support the Core network. Father of two.

Based on knowledge I have gathered piecemeal in the field, and on my own early-days feeling of wishing there were "a single, well-organized Japanese learning resource", I am building this site with the aim of creating material that people who learn later can follow systematically.
