5G Delay-Tolerant Data Services for Relay Duplicate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G networks face inefficiencies in handling delay tolerant data, leading to unnecessary network resource usage due to duplicate data transmissions and lack of end-to-end path optimization, particularly in scenarios involving IoT devices communicating with M2M servers via relays.
Innovation Solution
Implementing Delay Tolerant Data Services (DTDS) within the 5G core network (DTDS@CN) and relays (DTDS@UE) to optimize network resources by providing services such as duplicate detection, aggregation, advanced filtering, reliability assistance, error correction, and specialized charging, using DTDtags to manage delay tolerant traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If duplicate data transmissions are allowed to increase delivery reliability, then data delivery success rate improves, but network resource waste increases
Solution Approach 1:
The network entity receives feedback information from the second relay node indicating whether it has received duplicate data bundles. Based on this feedback, the network entity sends control information to instruct the second relay node to discard duplicate data, thereby preventing network resource waste while maintaining delivery reliability through selective retransmission.
Solution Approach 2:
A network entity acts as an intermediary between relay nodes to coordinate data bundle reception and transmission. The network entity receives data bundles from relay nodes, manages duplicate detection through feedback mechanisms, and controls the relay nodes to discard duplicates, thus optimizing network resource usage while ensuring reliable delivery.
2Reliability
If data is transmitted to multiple relays to improve delivery reliability, then data delivery success rate improves, but network resource usage increases
Solution Approach 1:
Relay nodes send feedback information to the network entity about their data bundle reception status. The network entity uses this feedback to send control information instructing relay nodes to discard duplicates, thereby reducing the quantity of data transmitted through the network while maintaining reliable delivery through coordinated multi-relay transmission.
Solution Approach 2:
Relay nodes autonomously discard duplicate data bundles based on control information received from the network entity. This self-service mechanism allows relay nodes to independently manage their data forwarding decisions, reducing overall network resource consumption while maintaining delivery reliability through coordinated operation.
3Productivity
If duplicate detection and resolution mechanisms are implemented, then network resource efficiency improves, but system complexity increases
Solution Approach 1:
The network entity serves as a centralized intermediary that manages duplicate detection and resolution. By concentrating the complex duplicate management functions in a single network entity rather than distributing them across all relay nodes, the system achieves improved network resource efficiency while limiting the complexity increase to a centralized controller rather than proliferating complexity throughout the network.
