5G Delay-Tolerant Data Routing With Duplicate-Aware Relays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G networks face inefficiencies in managing delay tolerant data traffic, leading to unnecessary duplication, resource waste, and unreliable delivery due to lack of network awareness of data duplicates and optimal relay paths.
Innovation Solution
Implementing Delay Tolerant Data Services (DTDS) within the 5G core network (DTDS@CN) and relays (DTDS@UE) to optimize network resources by identifying delay tolerant traffic, providing reliable delivery, path optimization, and offering services such as duplicate detection, aggregation, advanced filtering, reliability assistance, error correction, prioritization, and specialized charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is sent to multiple relays to improve delivery reliability, then delivery reliability is improved, but network resource waste increases due to duplicate transmissions
Solution Approach 1:
The patent applies preliminary action by implementing duplicate detection mechanisms at relays before data is transmitted across the network. Relays check incoming data bundles against stored copies using identifier matching, preventing duplicate transmissions from propagating further. This proactive approach eliminates wasted network resources while maintaining the reliability benefits of multi-relay transmission strategies.
2Reliability
If data bundles are transmitted to multiple relays to ensure delivery, then delivery reliability is improved, but network resource utilization deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where relays report received data bundle identifiers to a central coordinator or share information with peer relays. This feedback loop enables the network to track which data has been successfully delivered and which relays have copies, allowing dynamic adjustment of transmission strategies. The system learns from transmission outcomes to optimize future routing decisions, improving resource utilization while maintaining reliability.
3Loss of information
If duplicate data copies are eliminated at endpoints only, then data integrity is maintained, but network resources are wasted during transmission
Solution Approach 1:
The patent introduces relays as intermediary nodes that perform duplicate detection and elimination functions. Rather than relying solely on endpoint verification, relays act as intermediaries that check for duplicates using identifier matching and prevent redundant transmissions. This distributed approach at intermediary nodes reduces network waste while maintaining data integrity, as duplicates are eliminated before consuming significant network resources.
