Understanding NEC’s Near-RT RIC
The Near-RT RIC platform operates on general-purpose computing hardware and supports dynamic reconfiguration of RAN parameters based on network conditions and service requirements. This flexibility is essential for optimizing network performance across diverse deployment environments, from dense urban centers with high user demand to remote locations requiring efficient spectrum utilization.
Key Features and Capabilities
- Dynamic Load Balancing
One of the most critical functionalities integrated into NEC’s Near-RT RIC is its ability to balance network traffic between different cells dynamically. Cellular networks often experience uneven traffic distribution due to user mobility, environmental factors, and varying application demands. Without intelligent load balancing, certain cells may become overloaded, leading to degraded service quality and poor user experience.
By continuously monitoring network utilization and traffic distribution, the Near-RT RIC can adjust power levels, handover thresholds, and carrier aggregation parameters to redistribute load effectively. This ensures that no single cell becomes a bottleneck, enhancing overall network performance while maintaining consistent service quality for end-users.
- SLA-Based Network Slicing Management
Network slicing is a fundamental aspect of 5G, allowing operators to allocate specific resources for different applications or industries. NEC’s Near-RT RIC enhances network slicing by dynamically managing radio resources to meet predefined Service Level Agreements (SLAs). For example:
- Ultra-Reliable Low Latency Communications (URLLC) applications, such as remote surgery and autonomous driving, require extremely low latency and high reliability.
- Enhanced Mobile Broadband (eMBB) services demand high throughput and capacity for applications like 4K video streaming and AR/VR.
- Massive Machine-Type Communications (mMTC) necessitate efficient spectrum utilization for IoT devices deployed at scale.
NEC’s RIC continuously monitors network conditions and automatically reallocates resources to maintain SLA compliance. This adaptability ensures that mission-critical applications receive priority when needed without compromising other network slices.
- Latency Optimization for High-Reliability Use Cases
Low-latency communication is one of the defining features of 5G, crucial for applications requiring instantaneous response times. NEC’s Near-RT RIC employs AI-driven analytics to detect and mitigate latency issues in real time. By optimizing scheduling policies, adjusting transmission power, and fine-tuning radio parameters at an individual user level, the system minimizes transmission delays and packet loss.
In NEC’s recent demonstrations, this technology significantly reduced latency violations in 5G vRAN environments. For instance, when used in an indoor setting for remote mobile robot operation, the RIC-enabled system cut down instances of excessive latency to less than one-sixth compared to non-RIC implementations. Such improvements are particularly relevant for industrial automation, smart factories, and remote healthcare applications.
Demonstrating Real-World Benefits of NEC’s Near-RT RIC
Use Case: 5G vRAN for Industrial Automation
The rise of Industry 4.0 has increased the demand for ultra-reliable wireless connectivity in manufacturing and industrial operations. Traditional wired infrastructure is often impractical in dynamic environments where robotic arms, automated guided vehicles (AGVs), and IoT sensors must communicate seamlessly.
NEC’s Near-RT RIC enables precise network control, reducing jitter and ensuring that critical data packets arrive on time. By integrating with AI-based predictive analytics, it can preemptively adjust network parameters based on historical data, minimizing disruptions due to interference, congestion, or unexpected traffic surges.
For example, in a smart factory setting, sensors monitoring production lines continuously generate large volumes of data. With NEC’s RIC, the network can dynamically prioritize this telemetry data, ensuring real-time analysis and intervention when quality thresholds deviate. This prevents costly downtimes and enhances overall operational efficiency.
Use Case: 5G for Smart Cities and Public Safety
Smart city infrastructure relies on interconnected networks of surveillance cameras, traffic sensors, and emergency response systems. Public safety applications require uninterrupted connectivity, particularly for real-time video feeds and automated threat detection algorithms.
With NEC’s RIC-driven optimizations, municipalities can implement adaptive QoS policies, ensuring that emergency services always have priority bandwidth. In scenarios such as disaster response, where mobile networks experience sudden surges in traffic, the RIC dynamically reallocates resources to ensure critical communications remain unaffected.
Additionally, smart traffic management systems can benefit from NEC’s RIC by reducing latency in vehicle-to-everything (V2X) communications. For example, adaptive signal control systems use AI-driven traffic data to adjust stoplight timing dynamically, reducing congestion and improving urban mobility.
Use Case: Private 5G Networks for Enterprises
As enterprises adopt private 5G networks to support operations, NEC’s RIC provides a powerful solution for managing performance in complex deployments. Whether used in logistics hubs, mining operations, or large corporate campuses, private networks require intelligent resource allocation to handle mission-critical applications efficiently.
By deploying NEC’s RIC, enterprises gain real-time control over their network infrastructure, ensuring that bandwidth-intensive applications (such as augmented reality for training simulations) do not interfere with time-sensitive industrial control systems. The ability to fine-tune radio parameters on demand allows businesses to optimize their networks for specific operational needs.
Technical Architecture and Integration with O-RAN Standards

- AI/ML Processing Engines: Algorithms trained to recognize patterns in network behavior, predicting and mitigating performance degradations before they impact users.
- Open APIs: Standardized interfaces that allow operators to develop and deploy custom applications tailored to specific network requirements.
By decoupling RIC functions from traditional RAN implementations, NEC enables network operators to introduce innovative features without extensive hardware modifications. This modular approach accelerates the adoption of new AI-based network optimizations as they become available.
AI-Driven Decision Making
AI plays a central role in NEC’s RIC, leveraging real-time analytics and historical performance data to make intelligent network adjustments. The AI engine continuously refines its models based on observed network behavior, improving accuracy and effectiveness over time.
For example, during periods of high user activity, the AI model can predict future congestion patterns and proactively allocate additional spectrum resources to mitigate service degradation. This predictive capability significantly enhances network efficiency, ensuring smooth operation even under fluctuating conditions.
