Effnet 5G Non-3GPP Access Solution Examples

Some examples of untrusted/trusted/wireless access networks

As the 5G ecosystem continues to evolve, the integration of Non-3GPP Access has become essential for delivering seamless and reliable connectivity across diverse environments. Non-3GPP Access refers to the ability of 5G networks to connect with networks that are not part of the traditional 3GPP standards, such as Wi-Fi, satellite, and wireline networks. This capability is crucial for extending 5G coverage and enhancing the user experience, enabling devices to switch between different network types without interruption.

The 5G Core Network is a highly flexible system based on a service-based architecture, software defined networking, network slicing etc. It provides authentication, authorization as well as data session services.

By enabling integration of various other (not defined by 3GPP, i.e. “non-3GPP”) access technologies, the 5G Core Network can be made access-agnostic and provide an effective solution for data congestion, capacity and coverage issues as well as enabling new use cases. This makes 5G services available also over other access networks such as e.g. Wi-Fi, satellite and wireline.

A user terminal or a device receives services e.g. connectivity to internet and to other users, or specific applications, from a 5G Core. When a device connects to a 5G Core via a 5G radio network, the device is a 5G device, containing a 5G protocol stack. It is also possible for a device to connect to a 5G Core via a non-3GPP network e.g. a Wi-Fi network, a satellite network or a wireline network. Such a device may have some components of a 5G protocol or none at all. These devices connect to a 5G Core via special nodes or functions implemented/connected to their respective network i.e. Wi-Fi, satellite or wireline networks. These special nodes or functions contain 5G protocol stack components to enable a device to connect to 5G Core.

Non-3GPP Access for 5G-aware devices

The diagram to the right illustrates the control plane architecture for 5G-aware devices accessing Non-3GPP networks. In this setup, the terminal is equipped with both NAS (Non-Access Stratum) and EAP-5G (Extensible Authentication Protocol for 5G), which handle authentication and signaling. On the network side, the N3IWF (Non-3GPP Interworking Function), TNGF (Trusted Non-3GPP Gateway Function), or W-AGF (Wireline Access Gateway Function) manages these interactions using EAP-5G and NGAP (Next Generation Application Protocol), ensuring secure and efficient communication between the device and the 5G core network.

The diagram to the left shows the user plane architecture for 5G-aware devices when accessing Non-3GPP networks. The terminal maintains a PDU (Protocol Data Unit) session, which includes QoS (Quality of Service) flow control to manage data traffic efficiently. On the network side, the N3IWF, TNGF, or W-AGF is responsible for PDU-SUPP (PDU Session User Plane Protocol), facilitating the smooth transfer of user data between the terminal and the 5G core network while ensuring that QoS requirements are met.

Non-3GPP Access for non-5G-aware devices

In the diagram to the right, the control plane architecture is presented for non-5G aware devices accessing Non-3GPP networks. The 5G functions are offloaded to the TWIF (Trusted Wireless Interworking Function) or W-AGF on the network side. The TWIF/W-AGF handles all control signaling, including NAS/NGAP, to enable secure and reliable communication between the non-5G aware device and the 5G core network.

The diagram to the left highlights the user plane architecture for non-5G aware devices when connected to Non-3GPP networks. Without native support for PDU sessions or QoS flow control in the terminal, these functions are managed entirely by the TWIF or W-AGF. The TWIF/W-AGF ensures that user data is effectively transmitted between the non-5G aware device and the 5G core network, maintaining the necessary QoS levels for an optimal user experience.

The Effnet 5G Non-3GPP Access Solution is designed to empower network operators, terminal and gateway manufacturers as well as network vendors by offering comprehensive support for Non-3GPP Access across both network and terminal sides. Whether you are looking to integrate trusted Wi-Fi networks, manage untrusted access points, or support wireline access, our solution provides the flexibility, security, and performance.

Use Cases

Trusted Non-3GPP Access

Trusted networks, such as carrier-grade Wi-Fi, play a critical role in providing seamless 5G connectivity. With Effnet solution, operators can easily integrate these trusted networks into their 5G infrastructure, ensuring smooth and secure handovers between 5G and Wi-Fi without compromising on performance or user experience.

Untrusted Non-3GPP Access

In scenarios where devices connect through untrusted networks (e.g., public Wi-Fi), Effnet solution offers robust mechanisms to ensure secure connectivity. Through advanced encryption and authentication protocols, we enable safe data transmission and protect against potential threats, allowing users to confidently connect across different networks.

Wireline Access

For enterprises and service providers looking to integrate wireline networks into their 5G offerings, Effnet solution provides the tools to seamlessly bridge these technologies. This integration ensures that users can experience the benefits of 5G even when connected through traditional wired networks, making it easier to deliver consistent and high-quality services.
