ICN Gateway and Point of Attachment for 5G Information Centric Networking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G architecture struggles to efficiently support Information Centric Networking (ICN) due to differences in communication models between ICN and traditional PDU sessions, leading to challenges in routing, charging, and quality of service (QoS) management.
Innovation Solution
The introduction of new data plane entities such as the ICN Point of Attachment (ICN-PoA) and ICN Gateway (ICN-GW) facilitates ICN within 5G networks by collecting UE-related information and interfacing with the gNB and data network, respectively, to manage ICN traffic and context information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional PDU session architecture is used in 5G networks, then existing network infrastructure can be maintained, but efficient support for ICN services cannot be achieved
Solution Approach 1:
The patent segments the 5G core network by introducing dedicated ICN functional entities (ICN-PoA and ICN-GW) that operate independently from the traditional PDU session architecture. This segmentation allows ICN services to be supported without disrupting existing network infrastructure, enabling multi-functionality through modular addition rather than complete architectural replacement
Solution Approach 2:
The patent introduces intermediary entities (ICN-PoA and ICN-GW) that bridge between ICN applications and the existing 5G core network. These intermediaries translate ICN-specific requirements into standard 5G network operations, allowing ICN services to be supported while maintaining compatibility with the traditional PDU session architecture
2Reliability
If ICN-specific entities are introduced to support ICN traffic, then ICN routing and QoS management are improved, but network infrastructure complexity increases
Solution Approach 1:
The ICN-PoA and ICN-GW entities are designed to perform multiple functions: they handle ICN packet routing, collect ICN context information, manage QoS parameters, and interface with both gNB and data networks. This multi-functionality reduces the need for separate specialized entities for each function, thereby managing complexity while improving reliability
Solution Approach 2:
The ICN-specific entities autonomously manage ICN traffic by collecting context information from UEs, making routing decisions based on ICN packet names, and enforcing QoS policies without requiring constant external control. This self-service capability improves reliability by enabling rapid local decision-making while reducing the complexity of centralized control mechanisms
Data Source
AI summary
Technology for an Information Centric Networking gateway (ICN-GW) operable to modify an ICN message received from a user equipment (UE) in a Fifth Generation (5G) cellular network is disclosed. The ICN-GW can decode the ICN message received from the UE via a Next Generation NodeB (gNB) and an ICN point of attachment (ICN-PoA). The ICN-GW can modify the ICN message to produce a modified ICN message. The ICN-GW can encode the modified ICN message to route the modified ICN message to a data network.
