5G Core Network Solution

5G core connects numerous users in a single, highly flexible network. It allows businesses and individual users to access a wide variety of services and applications. The new technology ensures high flexibility and full automation while providing better security measures.

5G core makes network management much more straightforward. The solution provides higher performance and stability compared to 4G, making it ideal for modern IoT devices and precise equipment. With 5G, users can transfer data in real time.

By using Axyom solution, businesses can create safe and reliable in-house networks. Our 5G solution is invaluable for communication service providers, as it allows the deployment of modern services and applications.

Capacity and Speed

The frequency band affects the amount of information radio waves can transfer through a network. 5G provide users with added capacity, which means you can add more users. Furthermore, each of these users will enjoy higher speed when browsing the Internet potentially up to 100 times faster than 4G.

More Devices

Previous network generations had a hard time connecting numerous devices on a small surface area. This made it almost impossible to use phones during music, sports, and other public events. 5G networks are designed to handle a massive increase in the number of connected devices compared to 4G (Up to 10 times more devices per square kilometre than 4G LTE) which is crucial for supporting the growing number of IoT devices, smart cities, and other connected applications.

Reliability

5G is designed to be more reliable and stable than 4G, with fewer dropped connections and better performance in crowded areas. This enhanced reliability is particularly important for mission-critical applications and services where consistent connectivity is essential.

Flexible Use

Through its versatility, 5G can be used for various use cases. Users no longer have to rely on special-purpose networks, as 5G core supports concept of network slicing, which allows a single physical network to be divided into multiple virtual networks, each optimized for a specific purpose. This allows for tailored network performance for different applications and user needs, optimizing resource allocation and enhancing overall capacity.

When it comes to 5G networks, control plane network functions are categorized based on services. As a result, experts commonly refer to this configuration as Service-Based Architecture or SBA. 

Here is a breakdown of the main 5G components:

• UE (User Equipment) 

  Includes all sorts of smartphones and IoT devices, rely on 5G New Radio Access Network to connect to the 5G core. Through RAN, UE can connect further down the line to the external network (e.g. Internet, IMS etc). 

•  5G Access Network (5G-AN) 

  Also known as a Radio Access Network (RAN), is the wireless component of a 5G mobile network that connects devices to the core network. It utilizes radio frequencies to provide wireless connectivity, enabling devices to communicate with the network and access services like the internet. 

• AMF (Access and Mobility Management Function) 

  Allows the user equipment to connect with the network. It handles registration, connection, and mobility management for user equipment (UE).

• AUSF (Authentication Server Function) 

  Assists AMF to help authenticate user equipment in order to enable them to connect to the 5G network.

• SMF (Session Management Function)

  Responsible for managing user sessions. Depending on user equipment’s request, AMF chooses appropriate SMF (Sessions Management Function).

• UPF (User Plane Function) 

  Responsible to transfer data traffic between external networks and user equipment. 

• PCF (Policy Control Function) 

  Responsible for policy control ensuring efficient resource allocation.

• UDM (Unified Data Management)

  Responsible for managing the subscriber 5G subscription information. 

• CHF (Charging Function) 

  Responsible for subscriber’s charging management. It supports both offline & online charging.

• NRF (Network repository function) 

  Responsible for 5GC service management & discovery. 

• NSSF (Network slice selection function) 

  Responsible for slice selection.

• NEF (Network exposure function) 

  Responsible for exposing 5GC capabilities to application functions (AF).

• N3IWF (N3 Interface Working Function) 

  Acts as a gateway for connecting non-3GPP access networks (like Wi-Fi) to the 5G core network (5GC). 

• AGF (Access Gateway Function) 

  Acts as a bridge between wireline networks and the 5G core network. It enables devices connected via traditional wireline infrastructure, like residential gateways, to interact with the 5G core network.

• SCP (Service communication proxy)

  It is a crucial network function in the 5G Service-Based Architecture (SBA) that acts as an intermediary for communication between network functions (NFs). Think of it as a central "switch" that manages how different parts of the 5G core network interact with each other.
