Relay Terminal Identification for UE-to-UE Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for UE-to-network relay cannot be reused for UE-to-UE relay, necessitating a new approach for secure communication between terminal devices.
Innovation Solution
A method involving a relay terminal device that determines and assigns identification information to terminal devices on a link, enabling secure communication by concealing real identities and preventing conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing UE-to-network relay solutions are used, then network relay functionality is provided, but they cannot be applied to UE-to-UE relay scenarios
Solution Approach 1:
The patent introduces an adaptation layer as an intermediary component between the existing relay functionality and the new UE-to-UE relay scenario. This adaptation layer modifies how identification information is handled and assigned, allowing the existing network relay solutions to work in UE-to-UE contexts without requiring complete redesign of the underlying relay mechanisms.
2Reliability
If real identities of terminal devices are used for identification, then direct communication is enabled, but security and conflict prevention are compromised
Solution Approach 1:
The patent implements preliminary assignment of identification information before actual communication occurs. The relay terminal device assigns temporary identification information to terminal devices in advance, which is then used during communication. This preliminary action prevents conflicts and enhances security without complicating the actual communication process, as the identification framework is already in place.
Solution Approach 2:
Instead of using real identities directly, the patent creates and uses copied identification information (temporary IDs assigned by the relay device). These copied identifiers serve the same functional purpose as real identities for communication and routing, but provide the necessary security and conflict prevention by decoupling the actual identity from the communication process.
3Reliability
If identification information is assigned for secure communication, then security is enhanced, but device complexity increases
Solution Approach 1:
The relay terminal device performs self-service by autonomously assigning identification information to terminal devices without requiring external intervention or complex centralized management. The relay device itself generates and manages the temporary identifiers, simplifying the overall system architecture while maintaining security. This self-service approach avoids the complexity of external identification management systems.

AI summary
A first terminal device connects with a second terminal device via at least one third terminal device acting as a relay between the first terminal device and the second terminal device. The first terminal device determines identification information for identifying the first terminal device and/or the second terminal device on a link between the first and second terminal devices. The first terminal device assigns the determined identification information to at least one corresponding hop on the link between the first terminal device and the second terminal device.
