Fast-Aiding RICs for 5G Network Resilience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio access network intelligent controllers (RICs) face challenges in quickly and intelligently providing aid to each other, especially in distributed 5G networks, leading to potential service disruptions and increased costs due to traditional scaling and orchestration methods.
Innovation Solution
Implementing a fast-aiding mechanism among RICs (FAAR) that uses policy, workflow, AI/ML, and other mechanisms to enable multiple RICs to quickly provide aid to each other, allowing for dynamic task distribution and resource sharing, thereby enhancing flexibility and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional scaling and orchestration methods are used to provide aid between RICs, then service continuity is maintained, but response time increases and operational costs increase
Solution Approach 1:
The patent implements a subscription mechanism where RICs pre-subscribe to aid offerings from other RICs before failures occur. This preliminary action establishes ready-made assistance relationships, so when a failure happens, the subscribed RIC can immediately provide aid without going through traditional orchestration procedures, thus reducing response time while maintaining service continuity
Solution Approach 2:
The patent introduces a communication interface as an intermediary layer between RICs that enables direct peer-to-peer aid exchange. This intermediary mechanism allows RICs to quickly share aid information and capabilities without involving complex traditional orchestration systems, reducing both response time and operational costs while ensuring service continuity
2Reliability
If traditional scaling methods are used to provide aid between RICs, then service continuity is maintained, but operational costs increase
Solution Approach 1:
The patent enables RICs to autonomously subscribe to and provide aid to each other without requiring complex traditional orchestration and scaling operations. This self-service mechanism allows RICs to independently manage their own failover relationships, reducing the need for expensive orchestration infrastructure and operational interventions, thereby lowering operational costs while maintaining service continuity
Solution Approach 2:
The patent combines multiple RIC capabilities and aid offerings into a shared pool through subscriptions. By merging resources and capabilities across RICs in a coordinated manner, the system can provide failover assistance using existing distributed resources rather than requiring additional centralized orchestration infrastructure, reducing operational costs while ensuring service continuity
3Productivity
If fast-aiding mechanism is implemented among RICs, then response time is reduced and operational costs are lowered, but system complexity increases
Solution Approach 1:
The patent segments the failover mechanism into independent subscription and offering components that can be implemented individually by each RIC. This segmentation allows RICs to adopt the fast-aiding mechanism in a modular way, managing complexity locally while achieving system-wide rapid response, thus improving productivity without proportionally increasing overall system complexity
Solution Approach 2:
The patent creates a universal communication interface and subscription mechanism that can be applied across different RIC implementations and scenarios. This universal approach consolidates the fast-aiding functionality into standardized patterns that can be reused throughout the system, improving response speed while reducing the need for custom complex orchestration logic in each scenario

AI summary
Fast-aiding radio access network intelligent controllers (RICs) can assist other RICs that are experiencing performance issues. The system can take into account the availability of other RICs that can aid the RIC needing assistance. Therefore, multiple RICs cooperatively working together can generate synergies, and allow differentiated RICs to operate in both predefined and/or dynamically create RIC groups. Once a RIC that needs assistance is identified, other RICs can offload functionalities that are less important than the functionality of the RIC that is experiencing the performance issues. After the assisting RIC has offloaded its functionalities, it can then devote resources to the RIC that needs the assistance.
