Overview

5GC (5G Core) is a mobile core network system designed to support 5G radio access networks.

NEC‘s 5GC features a highly open, cloud-native architecture that enables the use of 4G EPC functions within the 5GC framework. Its multi-platform design is compatible with both on-premises deployments and public cloud environments, offering a proven, high-performance software-based UPF (User Plane Function).

It is a mobile core solution that offers global deplorability, flexibility, compatibility, high performance, and high quality.

Features

NEC's 5GC provides a solution with the following features.

Fully Cloud-Native Converged Mobile Core

NEC 5GC’s architecture is a fully virtualized and containerized microservices architecture.
It supports multi-vendor environments and is not dependent on hardware.

Users can choose from a wide range of platforms, including private clouds, public clouds, and hybrid cloud environments. Multiple deployment architectures can be selected based on business needs.

NEC UPF also supports deployment on AWS Outposts, expanding cloud utilization options while respecting operators’ existing network designs and operational practices. Through seamless integration with managed services provided by AWS, it enables efficient cloud utilization while maintaining compatibility with existing environments.

Flexible UPF Local/Edge Model

By separating the C-Plane and U-Plane (CUPS), it becomes possible to design UPF in various deployment patterns, ranging from centralized aggregation to local edge. This realizes a flexible and highly scalable network architecture that meets service requirements and traffic characteristics.

NEC UPF, with its distinctive features of high performance and small footprint, enables coexistence with the functionalities required for the requirements and use cases demanded in edge environments.

As a result, it achieves both the required service performance and reduced power and space consumption, contributing to more efficient edge deployments, including Private 5G, and accelerating business growth toward the 5G-Advanced and 6G era.

4G EPC available on the 5G Core

Seamless migration from 4G to 5G is supported in both NSA (Non-Standalone) and SA (Standalone) architectures.

NEC 5GC provides a unified, consistent interface for the maintenance and operations of both 4G and 5G networks. It handles 4G/5G traffic comprehensively and can flexibly distribute resources according to the traffic ratio of 4G/5G.

Proven Software UPF Performance

The UPF is software-based and available on general-purpose servers.

Software-based architecture provides high adaptability to the evolution of hardware. This allows for the continuous delivery of high-performance UPF solutions.

It supports both 5G UPF functions and the U-Plane for 4G Gateways.

It comprehensively covers essential areas indispensable for the deployment and operation of 5G services, including core functions such as mobility control, session control, and the user plane, as well as cell broadcast and positioning services.

Additionally, NEC 5GC features Converged functionality, enabling the unified processing of both 4G and 5G traffic within a single software solution. This feature enables a simple and gradual transition from the existing EPC system to 5G infrastructure.

All NFs are delivered as containerized microservices and have been rigorously tested across Kubernetes, OpenShift, and major cloud platforms including AWS EKS. Designed for flexibility, they can be deployed across a variety of environments—on-premises, private cloud, public cloud, and hybrid cloud configurations—allowing for network designs that range from centralized to edge-distributed, tailored precisely to customer requirements.

By combining with the Network and Cloud Native Orchestrator, we automate and streamline every stage of network deployment and operations. Furthermore, by leveraging Agentic AI, we transform traditional workflow-based automation into intent-driven autonomy, delivering this as “SI Modernization.”

As one example of these initiatives, NEC has established a technology that leverages AWS’s AI tool “Kiro” to autonomously execute the entire lifecycle of the UPF—from design and deployment to operational monitoring, anomaly detection, and automated recovery. Traditionally, network operators would manually carry out tasks from network design to the initial service launch, which would take several weeks. However, by embedding NEC's expertise in network design and operation, cultivated in commercial networks, into AI, this period can be dramatically shortened to just a few hours.
These solutions enable operators to rapidly launch services and achieve stable operations without relying on highly specialized expertise or extensive human resources. NEC will further sophisticate the autonomy of networks as the foundation for solving social issues in the 6G era.

In the upcoming 6G era, where all devices and services will be continuously connected, mobile networks will further increase their importance as critical social infrastructure, alongside electricity and transportation.
NEC is looking ahead to such times and aims to realize next-generation networks that feature resilience to reliably support critical communications even during disasters or failures, an architecture that can be flexibly selected and expanded according to applications and requirements, and AI-native intelligent operations. By intelligently optimizing and controlling network resources with AI, operators can more flexibly and quickly design, deploy, and operate networks that meet increasingly diverse and sophisticated demands.
NEC will support the evolution of autonomous network infrastructures required in the future 6G era by continuous advancement of capabilities across the entire lifecycle—from design and deployment to operations—.
Thorough these initiatives, NEC will contribute to the development of a digital society with high reliability, enabling not only consumers but also businesses and municipalities to use its services safely and securely.

Benefits of the 5GC solution

Profitability

Creation of New Revenue Opportunities through High-Value Services

Expectations for mobile networks have evolved from merely providing connectivity to generating revenue through advanced services. The DPI (Deep Packet Inspection) capability integrated into NEC UPF identifies the types of traffic and applications, enabling prioritization of bandwidth for specific applications and the implementation of flexible pricing policies.

Improving Profitability through Enhanced User Perceived Quality

Mobile networks consist of various interconnected networks—such as RAN, transport, and core networks—that collaborate to provide communication services. These networks face the risk of declining user perceived quality due to differences in network speeds and congestion conditions. In particular, within RAN, fluctuation of radio waves and the density of users within the area can cause deterioration in communication quality.

NEC‘s TCP Optimization enhances profitability by intelligently controlling the density of data sent from the core network in response to RAN congestion conditions. This optimization improves RAN resource efficiency, helps reduce investment in base stations, and enhances users’ service experience. As a result, it contributes to the financial performance of telecom operators.

Scalability to Address Demand Fluctuations and High Business Continuity

Preparing for natural disasters and sudden traffic surges requires ensuring the flexibility and availability of networks. NEC‘s 5GC, with its hybrid cloud architecture, enables rapid utilization of cloud resources to restore services during disasters and dynamically adjusts resources during normal operations based on demand fluctuations. This features strengthen business continuity while enabling efficient resource utilization.

Building an Open and Flexible Network

With growing interest in open network architectures, multi-vendor system configurations have become a key requirement. NEC's 5GC offers platform flexibility, allowing for optimal utilization of existing infrastructure. It reduces dependency on specific vendors, enhancing both the scalability of services and operational flexibility.

Scalability

Automated Network Management

To address labor shortages and rising operational costs, the demand for automation in operations is surging. NEC’s 5GC minimizes human intervention in both on-premises and cloud environments. It not only reduces operational costs but also helps prevent human errors.
