Abstract

5G sets out to be the global connectivity and integration platform for a broad variety of industries in the upcoming decade. In order to do so it not only needs to fulfil the requirements of these industries but must also ensure its tight integration into the digital infrastructure of the 2020s by embracing key technologies. This article shows how one of these key technologies, the RESTful design of Application Programming Interfaces (APIs), is used in the 5G Service Based Architecture (SBA). The basic principles of modern API development are explained and it is shown how those integrate into the specific needs of the 5G Core Network.
