  9. Service-BasedArchitecture(SBA) • NFs offer services that other NFs consume. • NRF acts like a DNS server, facilitating service discovery. • Facilitates SDN and NFV concepts in 5G. • Server-Based Interface: • HTTP/2 Application Protocol • JSON Serialization Protocol • TCP Transport Protocol NRF Registration Discovery/Authorization Service Request/Authorization AMF SMF Source: 3GPP TS 29.500, TS 29.510

  13. ExposureCapability • AF - Application Function • App influence on traffic routing • Interacting with Policy framework for policy control • Accessing NEF • NEF - Network Exposure Function • Exposure of capabilities and events • Secure provision of information from external apps to 3GPP network. • Translation of internal-external information • Events related to users. • Information of Provision capability • Policy and charging capabilities • CN internal capabilities for analytics.

  17. Network Slice • A logical network that provides specific network capabilities and network characteristics. • Virtual network over a common shared physical infrastructure that can be created “on-demand” in order to meet specific needs of applications, devices, customers or operators. • Self-contained • Isolated • Configurable and Programmable • Multitenancy capability • Supports one or multiple type of services Source: 3GPP TS 23.501
