Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information centric network (ICN) architectures in cellular networks face inefficiencies due to host-centric communication and lack of optimal link resource utilization, particularly in next-generation networks, where multiple users requesting the same content leads to bottlenecks and suboptimal data delivery.
Innovation Solution
Implementing service request procedures that differentiate between UE-triggered and network-triggered requests, incorporating ICN-specific parameters and information, such as ICN names, security contexts, and mobility restrictions, to optimize data delivery and resource allocation in next-generation cellular networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If host-centric communication is used in ICN architecture, then communication simplicity is maintained, but link resource utilization becomes suboptimal and bottlenecks occur
Solution Approach 1:
The patent segments the ICN architecture into information-centric access function (ICN-AF) and information-centric user plane function (ICN-UPF) components. The ICN-AF handles control plane operations while ICN-UPF manages user plane data forwarding, enabling parallel processing and optimized resource utilization without compromising communication simplicity.
Solution Approach 2:
The patent introduces an information-centric access function (ICN-AF) as an intermediary between the host-centric communication layer and the network infrastructure. This mediator optimizes link resource allocation and prevents bottlenecks by intelligently managing data flows while maintaining the simplicity of host-centric communication interfaces.
2Adaptability or versatility
If multiple users request the same content simultaneously, then content delivery demand is met, but network bottlenecks and data delivery inefficiency occur
Solution Approach 1:
The patent merges multiple user plane data flows requesting the same content into a single optimized forwarding path through the ICN-UPF. By combining duplicate requests and utilizing content caching mechanisms, the system delivers content to multiple users simultaneously without creating proportional network load, thereby eliminating bottlenecks while maintaining high content delivery capability.
3Productivity
If ICN-specific parameters and information are incorporated in service request procedures, then data delivery optimization is achieved, but system complexity increases
Solution Approach 1:
The patent extracts ICN-specific parameters and information handling into a dedicated information-centric access function (ICN-AF) module. This separation allows the core service request procedures to remain simple while the extracted ICN-specific logic handles optimization tasks, thereby achieving data delivery optimization without significantly increasing overall system complexity.
Solution Approach 2:
The patent performs preliminary processing of ICN-specific parameters during service request establishment. By pre-configuring optimization parameters, caching policies, and forwarding rules before actual data transmission, the system achieves optimized data delivery without adding complex real-time processing requirements during data flow operations.
