Table - Acronyms

Acronym	Description
3GPP	3rd Generation Partnership Project 3GPP is the standard body for wireless communications
5G	Fifth Generation 5G is the fifth-generation technology standard for broadband cellular networks
CNC	Cloud Native Core CNC is a market-leading core network solution utilizing Cloud Native principles and architecture to deliver Service Agility, Innovation, Efficiency, and Adaptability for 4G and 5G network functions including an optional on-premises Cloud Native Environment
CSP	Communication Service Provider
C-NF	Consumer Network Function
HA	High Availability High-availability infrastructure is configured to deliver quality performance and handle different loads and failures with minimal or zero downtime
HTTP	Hypertext Transfer Protocol HTTP is an application-layer protocol for transmitting hypermedia documents, such as HTML. It was designed for communication between web browsers and web servers, but it can also be used for other purposes
HTTP2	Hypertext Transfer Protocol version 2 HTTP2 is a major revision of the HTTP network protocol used by the World Wide Web
JSON	Java Script Object Notation JSON is a language-independent, text-based data format that can represent objects, arrays, and scalar data
mTLS	Mutual Transport Layer Security mTLS authentication ensures that traffic is both secure and trusted in both directions between a client and server. It allows requests that do not log in with an identity provider (like IoT devices) to demonstrate that they can reach a given resource
MVP	Minimum Viable Product
NF	Network Function
NRF	Network Repository Function or Network Function Repository Function NRF is a key component of the 5G Service Based Architecture. It maintains an updated repository of all the NFs available in the operator's network along with the services provided by each of the NFs in the 5G core that is expected to be instantiated, scaled, and terminated with minimal to no manual intervention
P-NF	Producer Network Function
SBI	Service Based Interface SBI is the term given to the API based communication that can take place between two NFs
SCP	Service Communication Proxy SCP helps operators to efficiently secure and manage their 5G network by providing routing control, resiliency, and observability to the core network. It leverages IT service mesh (ISTIO) and adds critical capabilities to make it 5G-aware, thereby addressing many of the challenges caused by the new service-based architecture (SBA) in the 5G core
SEPP	Security Edge Protection Proxy SEPP as a 5G node is a non-transparent proxy that sits at the perimeter of the Public Land Mobile Network (PLMN) network and enables secured communication between inter-PLMN network messages. It is a Cloud native solution based on microservice architecture which acts as a non-transparent proxy sitting at the perimeter of the PLMN network enabling secured inter NF communication across PLMN networks
TCP	Transmission Control Protocol TCP is a connection-oriented protocol used by applications on networked hosts to connect to one another and to exchange streams of data in a reliable and in-order manner
TLS	Transport Layer Security TLS and its now-deprecated predecessor, Secure Sockets Layer, are cryptographic protocols designed to provide communications security over a computer network
