Cross-Domain Administrative Data Sharing via Distributed Ledger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing energy consumption in telecommunications networks due to the deployment of 5G and the anticipated demands of 6G, coupled with the challenge of cross-domain data sharing and privacy concerns, hinders effective energy efficiency management across network domains.
Innovation Solution
A method for sharing administrative data between network domains using a distributed ledger system, where a sharing function verifies and commits data records to a local copy, eliminating the need for a trusted third-party authority and enabling decentralized data sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized third party authority is used for data sharing, then data privacy and trust are improved, but device complexity and operational overhead increase
Solution Approach 1:
The patent extracts the trusted third party authority from the system and replaces it with a distributed ledger-based consensus mechanism. Each network domain maintains its own data while trusting the distributed ledger protocol, eliminating the need for a centralized authority while preserving data trust and privacy.
Solution Approach 2:
The distributed ledger acts as an intermediary between network domains, enabling them to share data without requiring a centralized mediator. The ledger provides a neutral, transparent platform where all domains can verify and consent to data sharing independently.
2Productivity
If cross-domain data sharing is enabled, then energy efficiency management is improved, but data privacy and security risks increase
Solution Approach 1:
The patent segments data ownership and control by maintaining separate data stores in each network domain while using the distributed ledger for coordination. This allows energy efficiency management across domains while preserving data privacy, as each domain retains control over its own data.
Solution Approach 2:
The system implements feedback mechanisms where network domains can verify data sharing requests and provide consent based on their policies. This enables cross-domain energy efficiency management while allowing domains to control their data privacy risks through selective participation.
3Ease of operation
If standardized interfaces are implemented for cross-domain sharing, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The distributed ledger provides a universal interface that works across all network domains regardless of their specific implementations. This standardized platform simplifies cross-domain data sharing operations while avoiding the complexity of multiple domain-specific interfaces.

AI summary
Disclosed is a method of sharing of administrative data between network domains. The method comprises: receiving a first administrative data record of a first set of administrative data records from a user plane function of the respective network domain; sending the first administrative data record by a sharing function of the respective network domain; receiving a second administrative data record of a second set of administrative data records by the sharing function of the respective network domain; verifying the first and/or second administrative data records; selecting a leader among the sharing functions of the network domains; and committing a third administrative data record of the first and second sets of administrative data records to a local copy of a distributed ledger of the network domains.
