Solution Overview

Problem

Edge Data Networks (EDNs) lack effective security measures and inefficiently record transactions, which poses risks to network integrity and data management.

Innovation Solution

The implementation of a Digital Ledger (DL) node within the network core that determines trust based on network information, combined with enhanced security protocols and transaction recording mechanisms, addresses the security and efficiency issues in EDNs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If Edge Data Networks are deployed near wireless access nodes to reduce latency, then service speed and responsiveness are improved, but security vulnerabilities and transaction recording inefficiency worsen

Engineering Contradiction:
Improveservice speedVSAvoidsecurity
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

A Digital Ledger node is introduced as an intermediary component within the network core that mediates between the edge data network and other network elements. This mediator verifies transactions and maintains security records, allowing the edge network to operate with high speed while the intermediary ensures security and reliability through cryptographic verification and immutable transaction recording.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If Edge Application Servers are distributed near users, then access efficiency is improved, but network security and transaction integrity worsen

Engineering Contradiction:
Improveaccess efficiencyVSAvoidtransaction integrity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The Digital Ledger node provides continuous feedback on transaction validity and network security status. Each transaction processed by distributed Edge Application Servers is recorded and verified by the ledger, which returns confirmation or rejection feedback. This feedback mechanism ensures that despite the distributed architecture improving access efficiency, transaction integrity is maintained through cryptographic verification and immutable recording.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If Edge Enablement Servers control Edge Application Servers in distributed EDNs, then service delivery flexibility is improved, but security monitoring and transaction recording efficiency worsen

Engineering Contradiction:
Improveservice delivery flexibilityVSAvoidtransaction recording efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The Digital Ledger node merges multiple security functions including transaction recording, verification, and security policy enforcement into a single centralized component within the network core. This consolidation allows distributed Edge Application Servers and Edge Enablement Servers to maintain high flexibility in service delivery, while the merged ledger system efficiently handles security monitoring and transaction recording through unified cryptographic operations and immutable data structures.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

In a wireless communication network (100), an Edge Enablement Client (EEC) (111) in a UE Gateway (GW) (110) exchanges EDGE-5 signaling with a user app (102) and exchanges EDGE-1 signaling with a Gateway Enablement Server (GES) (112) in the GW (110). The GES (112) exchanges EDGE-9 signaling with an Edge Enablement Server (EES) (122) in an Edge Data Network (EDN) (120) and exchanges EDGE-3 signaling with a Gateway Application Server (GAS) (113) in the GW (110). The GAS (113) exchanges user data between the user app (102) and an Edge Application Server (EAS) (123) in the EDN (120) responsive to the EDGE-3 signaling. The EES (122) exchanges additional EDGE-3 signaling with the EAS (123). The EAS (123) exchanges the user data between the GAS (113) and a network core (130) responsive to the additional EDGE-3 signaling. The core (130) exchanges the user data with the AS (140) and transfers network information for the exchange to a Digital Ledger (DL) node (150). The DL node (150) determines trust based on the network information.
