Today, we'll talk about RAN Intelligent Controllers, or RICs. Can someone tell me what they think RICs might do in a network?
Isn't it about improving the network’s intelligence and automation?
Exactly, Student_1! RICs bring intelligence to the Radio Access Network by applying AI and machine learning for real-time optimizations.
How do they interact with the network?
Great question! There are two types of RICs: the Near-Real-Time RIC, which works within milliseconds, and the Non-Real-Time RIC, which operates on a longer timescale.
What is the main job of each of these RICs?
The near-RT RIC focuses on immediate optimizations like traffic steering, while the non-RT RIC handles broader tasks like policy management.
So, to remember these, think of 'Near-RT for quick fixes' and 'Non-RT for long-term planning'.

RAN Intelligent Controllers (RICs)
Open RAN introduces RAN Intelligent Controllers (RICs), which are software-defined components designed to enhance the intelligence and automation capabilities of the Radio Access Network (RAN).
Types of RICs
- Near-Real-Time RIC (near-RT RIC): Operates within a timescale of 10ms to 1s and applies AI/ML algorithms to optimize network functions such as traffic steering, mobility management, and interference mitigation. This controller can react swiftly to changing network conditions to improve performance and user experience.
- Non-Real-Time RIC (non-RT RIC): Functions on a longer timescale (1s or more) and interfaces with orchestration systems for broader, long-term planning and optimizations. It focuses on policy management, energy-saving strategies, and training AI models for the near-RT RIC to further enhance its optimization capabilities.
Benefits of RICs
- Automation: RICs enable unprecedented levels of network automation, alleviating the need for constant human intervention and allowing for self-optimizing networks.
- Programmability: Their software-driven nature allows for flexibility in adapting to new applications and features without substantial hardware changes, promoting innovation.
- Vendor Interoperability: By utilizing open, standardized interfaces, RICs facilitate the integration of components from multiple vendors, promoting a competitive market and reducing reliance on single suppliers.
These innovations signify a transformational approach to managing RANs, enabling them to learn from the operational data and adapt to user demand and environmental conditions, ultimately leading to improved service reliability and quality.

Chapter Content
O-RAN introduces a new logical component, the RAN Intelligent Controller (RIC). RICs are software-defined controllers that sit above the traditional RAN layers.
Detailed Explanation
RAN Intelligent Controllers (RICs) are part of the Open RAN architecture. They function as intelligent software layers that optimize various operations within the Radio Access Network (RAN). Instead of being hardware-based, like traditional network controls, RICs use software algorithms to manage network traffic and enhance performance. They perform functions such as traffic management and interference mitigation, which are essential for maintaining high-quality service in a wireless network.
Examples & Analogies
Imagine RICs as smart traffic lights in a busy city. Just as traffic lights adjust their timings based on real-time traffic conditions to improve the flow of vehicles, RICs manage data flows in a network, adjusting how resources are allocated based on current demand.

Chapter Content
Near-Real-Time RIC: Operates on a timescale of 10ms to 1s. It uses data from the O-DU/O-CU (via the E2 interface) and applies AI/ML algorithms to perform intelligent optimizations like traffic steering, mobility management, and interference mitigation.
Detailed Explanation
The Near-Real-Time RIC is a crucial component for quick adjustments in the RAN. It processes data every 10 milliseconds to 1 second, allowing it to react swiftly to changing network conditions. By utilizing Artificial Intelligence (AI) and Machine Learning (ML), it can analyze traffic patterns and optimize network operations, such as directing users to less congested paths, ensuring better service quality. For example, if one part of the network is overloaded, the Near-RT RIC can redirect traffic to a different base station that is less busy.
Examples & Analogies
Think of the Near-RT RIC as a smart navigation app that reroutes drivers when it detects heavy traffic. Just like how a navigation app assesses traffic conditions and finds a faster route, the Near-RT RIC analyzes current data to optimize how mobile users are served.
Non-Real-Time RIC (Non-RT RIC)

Chapter Content
Non-Real-Time RIC: Operates on a timescale of 1s or more. It interfaces with higher-level orchestrators and performs broader, longer-term optimizations (e.g., policy management, AI model training for the near-RT RIC, energy saving strategies).
Detailed Explanation
The Non-Real-Time RIC operates on a longer timescale, typically more than one second, and focuses on overarching network management strategies. It handles policy decisions and guides the Near-RT RIC by setting long-term goals for resource management and efficiency. For instance, it may analyze historical data to understand usage patterns and implement strategies to save energy during off-peak hours, ensuring cost efficiency and sustainability in operations.
Examples & Analogies
Consider the Non-RT RIC as a city planner who uses data about traffic patterns to design road systems that accommodate future growth. Just as a planner considers long-term trends in population and vehicle use, the Non-RT RIC assesses network usage over time to make informed decisions about resource allocation and management.

Chapter Content
The RIC allows for unprecedented levels of automation, self-optimization, and programmability in the RAN, moving away from static, human-configured networks.
Detailed Explanation
The introduction of RICs has revolutionized the management of Wireless Access Networks by enabling extensive automation. This reduces the need for manual configuration and intervention, leading to more efficient operations. With self-optimizing capabilities, RICs can adjust network parameters dynamically in real-time, ensuring optimal performance and service availability without human input. This shift to automation also means that networks can be reprogrammed quickly to adapt to changing demands or implement new services.
Examples & Analogies
Think of RICs as an automated home system that regulates temperature, lighting, and security without needing daily manual adjustments. Just as such a system adapts to your preferences and routines, RIC technology automatically adjusts network functions to optimize performance and efficiency.
