Most people believe that faster connectivity is the best feature of the 5G. Although we can’t neglect that the new generation networks offer much better performance, the true technological shift comes from dynamically consumed capabilities.
Instead of selling bandwidth, telcos now have a chance to monetize different services. Slicing, analytics, Quality of Service, location, and policy control offer intriguing options for businesses that want to capitalize on secure interfaces. Instead of being perceived as a telecommunication network, many people now consider 5G a unique platform with versatile features.
The main reason behind the lightning-fast evolution lies in 5G NEF (Network Exposure Function). The NEF’s primary role is to connect internal 5G core capabilities and external applications. Besides ensuring maximum security, the function is vital for implementing monetization, governance, and policies.
Telcos benefit from NEF by unlocking new revenue streams. Businesses use the function to introduce programmable connectivity to their daily operations. Application developers and partners can utilize NEF to create an interface to network intelligence, an option that wasn’t available beforehand.
The Network Exposure Function is a part of the 5G core’s SBA (Service-Based Architecture). It is a standardized function created in accordance with 3GPP standards. Its main role is to expose specific network events and capabilities to authorized internal and external application functions. In other words, it serves as a unique API gateway vital for the network’s operations.
Network Exposure Function performs several important tasks:
Like any other function within a 5G network, NEF interacts with other components. Among others, it’s responsible for coordinating operations between several core functions:
One thing to note is that NEF can’t replace the security measures as it relies on authorization, authentication, and routing control introduced across the 5G core. Exposure is added on top of the existing security infrastructure, but it wasn’t meant to substitute it.
While telco managers appreciate the technical improvements, they are much more concerned about the potential revenue increase that NEF unlocks.
Operators can introduce new API-based packages that offer network capabilities to large clients. For example, businesses can subscribe to network status insights, guaranteed QoS tiers, application-triggered bandwidth boost, and device location services. Instead of using the same static options as everyone else, clients can program features according to their particular needs.
Enterprises can leverage NEF exposure to interact with slices customized to meet their unique performance requirements. This new service has become essential for different industry verticals, including media, logistics, manufacturing, and healthcare.
Application providers can request differentiated network performance for selected user segments. This makes it possible to deliver tiered digital experiences that are directly powered and enforced by network-level intelligence.
The best way to achieve massive IoT deployment is by leveraging policy-driven network interactions and event exposure. Fleet management, smart metering, and industrial innovation are all heavily reliant on programmable connectivity.
Telcos that adopt NEF solutions can enhance partners’ ecosystems by enabling third-party service providers to use network APIs and resell enhanced services to end users. In these situations, NEF becomes a vital component for ushering in B2B2X strategies.
The 5G networks rely on SBA, which is built on RESTful APIs, HTTP/2, service registration and discovery, and cloud-native deployment models. Here’s a breakdown of all the components that matter to NEF:
API exposure is essential for increasing the number of external interaction points and signaling traffic. By improving routing control, telcos are able to address overload, congestion, and uncontrolled service invocation.
Furthermore, telcos require scalable services that combine secure inter-service routing, mesh logic, and visibility across API flows. This is where Titan.ium 5G core comes into play. With our solution, operators can enjoy more control over signaling, secure routing, and exposure governance.
Using APIs without proper controls exposes operators to major financial and operational risks, including:
With our advanced solutions, operators gain a reliable, secure infrastructure necessary for exposure ecosystems:
The great thing about Titan.ium is that it provides maximum security for exposure ecosystems. It is a reliable solution that future-proofs your system, as it offers unprecedented versatility.
The Network Exposure Function exposes capabilities while the Policy Control Function determines their application. The combination of these two functions serves as the basis for the monetization loop, enabling:
Through policy integration, operators can introduce enforceable business logic to exposure. Otherwise, policy stays internal and non-monetizable.
Here are four real-world scenarios that operators might encounter:
An enterprise application requests temporary high-priority QoS for a mission-critical workflow. Here’s what different functions provide in this particular scenario:
A local government introduces connectivity and location events for traffic sensors:
A roaming partner asks for access to particular events.
A streaming company dynamically activates enhanced QoS during peak events.
Each of these scenarios is dependent on controlled discovery, protection, secure routing, and enhanced visibility. With Titan.ium, you can enjoy all these advantages and much more.
Aside from enabling APIs, you must make the following considerations before Network Exposure Function deployment:
Titan.ium’s infrastructure components support all these features, allowing operators to get the most out of NEF.
The 5G NEF is a programmable gateway that changes the 5G core from a basic connectivity enabler to a full-fledged service platform. The function is critical for exposing network intelligence, enabling enterprise monetization, powering B2B2X business models, and supporting QoS differentiation, slicing, and IoT ecosystems.
Nevertheless, NEF requires a robust 5G core ecosystem to provide the biggest benefits. In the right environment, it becomes a growth driver for telcos looking to transition to programmable solutions.
