NOTAS: | "5G core networks are based on service-based architecture (SBA), which is centered around network function (NF) services. Each NF can register itself and its supported services to a Network Repository Function (NRF), which is used by other NFs for the discovery of NF instances and their services.
Any NF can use the services another NF provides, and it is also possible to connect to other NFs without introducing specific new protocols or interfaces. This enables a more flexible development of services as well as a more flexible way to connect to a new NF type; thus, 3GPP core networks have gone from 4G telecom-style protocol interfaces to 5G web-based APIs..." |
