CONTENTS

This condensed 5G Core Network Architecture course is intended to give a good understanding of how the 3GPP standards define the technology for a core network that is stable, secure, scalable and (relatively) cheap to deploy and maintain, and can provide cost-efficient handling and data transfer for the huge variety of applications that the 5G networks are expected to service.

It has been designed to be covered by students within one normal working day. This course also exists as a full three-day course, and as an one hour overview variant.
