As the telecom industry continues to evolve and adopt new technologies, and businesses increasingly seek innovative approaches to manage and optimize their network infrastructure, Intent-Based Networking (IBN) has emerged as a game changer. IBN revolutionizes network management by enabling organizations to define their desired outcomes and automatically configuring networks to meet those objectives. One of the vital components of IBN that enables the implementation of this transformative paradigm is RIC - RAN Intelligent Controller.

What is RAN Intelligent Controller?

RIC or RAN Intelligent Controller is an end-to-end automation platform that optimizes Radio Access Network (RAN) communication functions and is crucial in facilitating intent-based networking. It is an artificial intelligence and machine learning based system that aids mobile operators in making better-informed decisions by providing real-time analytics.

As a central component of the RAN architecture, RIC is responsible for implementing intelligence and programmability in the RAN, enabling dynamic control and optimization of radio resources. It leverages its advanced automation, optimization, and analytics capabilities to enhance the RAN's performance, efficiency, and intelligence. RIC is the centralized controller interacting with various RAN elements, such as base stations, antennas, and other radio resources, to orchestrate and optimize their operations. It uses open interfaces and APIs to communicate with the RAN elements and exchange control commands and information. It collects data from these elements, analyzes it in real time, and makes intelligent decisions to optimize network performance and user experience. The RIC can dynamically allocate resources, adjust network parameters, and implement policies based on the current network conditions and requirements. 

The RAN Intelligent Controller is crucial in enabling network automation and orchestration. It automates various tasks and processes within the RAN, reducing manual efforts and improving operational efficiency. By orchestrating the allocation of resources, optimizing network performance, and managing network functions, the RIC helps streamline operations and ensure the delivery of high-quality services in IBN. 

RIC Global Market Outlook

Grand View Research

• The global RAN intelligent controller market size was valued at USD 137.1 million in 2022 and is expected to expand at a compound annual growth rate (CAGR) of 60.8% from 2023 to 2030 to reach USD 6071.1 million by 2030.
• Increasing digitization and the growing need to manage network traffic are driving market growth.
• Use cases of the RAN intelligent controller include optimizing quality-of-Experience (QoE) and Quality-of-Service (QoS), traffic steering, and resource utilization.

Integrating RIC with Intent-Based Networking

Intent-based networking aims to align network operations with business objectives. By leveraging artificial intelligence (AI) and machine learning (ML), IBN systems can translate high-level business intent into actionable network configurations. RIC complements IBN by providing granular control and optimization capabilities specifically for the RAN.

One of the key goals of the RAN Intelligent Controller is to enable the implementation of intent-based networking within the RAN. It acts as a central intelligence hub and translates high-level intent statements from network administrators or applications into specific policies and configurations for the RAN. This allows administrators to express their intent or desired outcomes in a more abstract and business-centric manner. At the same time, the RIC takes care of translating and implementing those intents into actionable network configurations.

Key Features of RAN Intelligent Controller

Intent Translation

Acting as a bridge between the network infrastructure and the intent-based software layer, the RIC translates high-level intent commands from network administrators or operators into concrete actions within the RAN. This simplifies network management and allows faster and more accurate execution of intent-driven policies.

Real-Time Optimization

RIC continuously monitors the RAN's performance, including radio conditions, traffic patterns, and user demands. It dynamically adjusts RAN policies to optimize resource allocation, ensure efficient spectrum utilization, and deliver the best possible user experiences in real time.

Closed-Loop Automation

RIC establishes a closed-loop automation system in the RAN, continuously monitoring the network's performance against the intended goals. If any deviation is detected, RIC takes corrective actions to bring the RAN back to the desired state, ensuring consistent service levels and quality of experience.

Network Intelligence and Analytics

RIC incorporates ML algorithms and AI techniques to analyze network data continuously. It gathers data from various RAN elements and performs advanced analytics to gain insights into network behavior and performance. It leverages this intelligence to proactively identify potential issues, predict network trends, and optimize resource allocation for enhanced efficiency.

Policy Enforcement

RIC enforces intent-based policies throughout the RAN to ensure the consistent application of network rules and regulations. By validating and implementing policies in real-time, the RIC enables network operators to maintain control over network behavior, security, and compliance.

Ecosystem Integration

RIC interfaces with other network orchestration and management systems as part of an intent-based networking paradigm. It exchanges information, receives high-level intent commands, and provides valuable insights to enable end-to-end network automation and optimization across the entire networking ecosystem.

Network Slicing

With the RIC, operators can create and manage multiple network slices tailored to user requirements and applications. This capability allows for optimized resource allocation and guaranteed quality of service, catering to the diverse needs of various industries and users within the same network infrastructure.
