ICN Handover via Content Request Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications systems, introducing Information Centric Networking (ICN) entities poses challenges due to limited resources on radio access nodes, such as eNBs, which can lead to insufficient capacity for handling high-demand events like football matches, where radio and processing resources are overwhelmed, and admission control struggles to manage future content volumes effectively.
Innovation Solution
A method for determining the need for handover of communication devices based on ICN requests, ensuring sufficient allocation of radio resources and distributing network capacity across available base stations, using content availability and resource management to facilitate efficient handover and load balancing, thereby ensuring uninterrupted service and improved user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ICN entities are installed on radio access nodes to enable content-centric routing, then information delivery capability is improved, but processing and storage resources become insufficient
Solution Approach 1:
The patent segments the ICN functionality by separating content routing operations from traditional connectivity management. The ICN entity is divided into independent modules that can be selectively activated based on content requirements, allowing the system to handle information-centric tasks without overwhelming the radio access node's processing resources.
Solution Approach 2:
The patent introduces a new dimension for resource management by implementing layered admission control that operates at multiple levels: radio resource layer, processing resource layer, and storage resource layer. This multi-dimensional approach allows the system to accommodate ICN entities by distributing the load across different resource dimensions rather than concentrating demands on a single resource pool.
2Adaptability or versatility
If multiple UEs are allowed to access the network for high-demand events, then service coverage is improved, but radio resources become insufficient
Solution Approach 1:
The patent applies local quality by enabling different radio access nodes to have specialized roles based on their local capabilities and content availability. Some nodes are configured as content production points while others serve as consumption points, allowing efficient local content delivery without requiring all nodes to handle full service loads, thus optimizing radio resource utilization across the network.
Solution Approach 2:
The patent implements preliminary action through proactive content caching and pre-allocation of radio resources for anticipated high-demand events. By predicting content popularity and pre-positioning content at strategic ICN entities, the system prepares resource allocation in advance, reducing the need for intensive real-time resource management during peak demand periods.
3Ease of operation
If admission control is applied at registration time, then resource allocation is simplified, but future content volume demands cannot be predicted
Solution Approach 1:
The patent implements feedback mechanisms that continuously monitor content access patterns, resource utilization, and UE behavior. This feedback information is used to dynamically adjust admission control decisions and predict future content volume demands. The system learns from historical data and adapts its resource allocation strategies, combining the simplicity of registration-time control with the adaptability of predictive analytics.
Solution Approach 2:
The patent transforms static admission control into a dynamic system that adjusts its parameters based on real-time network conditions and content demand patterns. Admission control thresholds, resource allocation ratios, and ICN entity activation states are dynamically modified according to current load, content popularity, and predicted future demands, allowing the system to maintain simplicity while adapting to varying content volumes.
