Relay Terminal Identifier Conflict Handling in 5G NR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of 5G NR relay communication services, particularly for moving networks, identifier conflicts between terminals can lead to service reliability and quality issues due to inefficient handling of identifier conflicts, especially in millimeter wave environments where rapid changes in connectivity and terminal mobility occur.
Innovation Solution
A method and apparatus for efficiently handling identifier conflicts in relay communication services using wireless direct communications, which involves assigning preliminary identifiers for conflict resolution, releasing reservations for unmatched identifiers, and managing identifier updates to prevent overlaps, thereby reducing the likelihood of service disruptions and improving system efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identifier conflict handling procedures are made more comprehensive to ensure reliability, then service reliability improves, but processing delay increases
Solution Approach 1:
The system performs preliminary identifier assignment and conflict detection before actual relay communication establishment. The relay terminal pre-assigns identifiers to remote terminals and detects potential conflicts in advance, allowing for proactive resolution rather than reactive handling, thus reducing processing delay while maintaining reliability
Solution Approach 2:
The system implements a feedback mechanism where the relay terminal monitors identifier usage and detects conflicts in real-time. When conflicts are detected, the system provides feedback by notifying affected terminals and coordinating identifier reassignment, enabling dynamic adaptation that maintains service reliability without excessive delay
2Loss of time
If identifier conflict handling procedures are simplified to reduce processing time, then processing delay decreases, but service reliability deteriorates
Solution Approach 1:
The identifier conflict handling process is segmented into distinct phases: preliminary identifier assignment, conflict detection, conflict resolution coordination, and identifier update. This segmentation allows the system to process conflicts in manageable steps, reducing overall processing delay while ensuring each phase maintains necessary reliability checks
3Reliability
If comprehensive identifier management is implemented to prevent conflicts, then service quality improves, but device complexity increases
Solution Approach 1:
The relay terminal serves as an intermediary that centralizes identifier management functions. Instead of each terminal independently managing identifiers, the relay terminal coordinates identifier assignment and conflict resolution, simplifying the overall system architecture while maintaining comprehensive identifier management for improved service quality

AI summary
A method of handling an identifier conflict in a relay communication access service comprises receiving a relay communication request message from a remote terminal, obtaining an identifier of the remote terminal from the relay communication request message, assigning preliminary identifiers for identifier conflict handling based on the identifier of the remote terminal, and transmitting a relay communication response message including preliminary identifier information for the assigned preliminary identifiers to the remote terminal.
