ICN QoS Identifier for Cellular Network Packet Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G QoS architecture lacks support for quality-of-service (QoS) in information-centric networks (ICN), as there is no end-to-end PDU session established for ICN-based data delivery, leading to inadequate QoS handling for ICN packet delivery within the cellular network.
Innovation Solution
Extending existing control plane signaling to support QoS rule configuration for ICN-based data delivery by introducing an ICN QoS Identifier, which maps to QoS characteristics, enabling effective QoS handling for ICN packets within the 5G and 4G networks by leveraging unused QoS Indicator values and adding new characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing control plane signaling is used without extension, then the existing 4G/5G QoS architecture remains simple and unchanged, but QoS handling for ICN packets is inadequate and unsupported
Solution Approach 1:
The patent applies preliminary action by pre-defining QoS characteristics and ICN QoS Identifier mappings in the control plane before actual ICN packet transmission. The network elements are pre-configured with QoS rules and characteristics (priority, packet delay budget, packet error rate) so that when ICN packets arrive, the QoS handling is already established and ready, eliminating the need for complex real-time QoS negotiation
Solution Approach 2:
The patent makes the existing QoS architecture universal by extending it to support both traditional TCP/IP packets and ICN packets through a unified QoS framework. The same control plane signaling mechanisms and QoS characteristics are used for both packet types, allowing the network infrastructure to handle multiple protocols and architectures without requiring separate dedicated systems
2Reliability
If QoS characteristics are added for ICN packets, then QoS handling effectiveness improves, but the QoS architecture becomes more complex
Solution Approach 1:
The patent applies parameter changes by introducing new QoS characteristics specific to ICN packets (such as ICN QoS Identifier, priority levels, packet delay budget, packet error rate) while maintaining compatibility with existing QoS parameters. This allows the system to handle ICN-specific requirements without fundamentally redesigning the entire QoS architecture
Solution Approach 2:
The patent uses the ICN QoS Identifier as an intermediary element that bridges ICN packets and the existing QoS framework. This identifier acts as a key that maps ICN packets to appropriate QoS characteristics and handling rules, simplifying the integration process and reducing architectural complexity by providing a clear interface between ICN and traditional QoS mechanisms
3Ease of manufacture
If unused QoS Indicator values are leveraged, then implementation cost and complexity are minimized, but QoS granularity and control flexibility are limited
Solution Approach 1:
The patent changes the parameter space by extending the QoS Indicator value range to utilize previously unused values. Instead of being limited to traditional QCI or 5QI ranges, the system incorporates additional QoS Indicator values that provide finer granularity for ICN packet classification and QoS control, thereby increasing flexibility without requiring a complete redesign

AI summary
Systems and techniques for quality-of-service (QoS) in cellular information centric network (ICN) are described herein. An example system includes processing circuitry, and a memory that includes instructions, the instructions, when executed by the processing circuitry, cause the processing circuitry to obtain QoS characteristics for an ICN packet, apply the QoS characteristics to the ICN packet, and transmit the ICN packet over the cellular ICN in accordance with the QoS characteristics.
