What are the 5G core components?
The components of the 5G core architecture include:
- User plane Function (UPF)
- Data network (DN), e.g. operator services, Internet access or 3rd party services.
- Core Access and Mobility Management Function (AMF)
- Authentication Server Function (AUSF)
- Session Management Function (SMF)
- Network Slice Selection Function (NSSF)
What is a 5G standalone core?
The 5G core itself is designed as a Service Based Architecture (SBA) which virtualizes network functions altogether, providing the full range of 5G features enterprise needs for factory automation, autonomous vehicle operation, and more.
What does the core network do?
In telecommunications, the core network is the central element of a network that provides services to customers who are connected by the access network. A core/backbone network provides paths for the exchange of information between different sub-networks.
What stores the profiles of the network functions in the 5G core?
HSS (Home Subscriber Server) – is the unit that manages user profiles, subscriptions and security functions. HSS is responsible for e.g. user authentication when trying to connect to the network and authorization of access to selected services.
What is 5G core testing?
The 5G Core introduces new protocols, service-based architecture, virtualization, and network slicing, among other things. The elastic nature of the 5G Core network creates new challenges for testing the core network elements, both in isolation and in end-to-end setups.
What is difference between core and access network?
The access network is the network or the part of a telecommunications network that gives the user access to the telecommunications service. The core network (or backbone) is the part of a network that connects the different parts of the access network. The core network also provides the gateway tot other networks.
What is wireless core?
The evolved packet core (EPC) is the all-IP core network for LTE. It orchestrates major functions of the wireless network such as user authentication, mobility, policy enforcement, charging, deep packet inspection (DPI), interworking with legacy 2G/3G/CDMA networks and many others.
What is UPF 5G?
The User Plane Function (UPF) is a fundamental component of a 3GPP 5G core infrastructure system architecture. The primary goal CUPS was to support 5G New Radio (NR) implementations enabling early IoT applications and higher data rates.
What is 5G core and how does it work?
What is 5G Core? 5G Core (5GC) is the heart of a 5G mobile network. It establishes reliable, secure connectivity to the network for end users and provides access to its services.
What is the architecture of 5G network?
The 5G System architecture consists of the following network functions (NF) majority of which constitute the 5GC: Authentication Server Function (AUSF) Core Access and Mobility Management Function (AMF) Data network (DN), e.g. operator services, Internet access or 3rd party services.
What is the 3GPP 5G standard?
3GPP is a standard body that is defining both a new 5G core network (5GC) and a new radio access technology called 5G “New Radio” (NR). There are several options available to integrate between different generations of access network technology with the core network.
What is the NSA model of 5G?
In the NSA model, both NR radio cells and LTE radio cells use dual connectivity to provide radio access and the core network using EPC or 5GC. There are several 5G core network deployment options defined by 3GPP. 1. Standalone architecture (SA).
