D2D UE ID Conflict Resolution via Reallocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Device-to-Device (D2D) communication, conflicts arise when terminal IDs or group IDs are identical, leading to misdirected data packets and communication disruptions, as existing technologies lack effective methods for resolving these ID conflicts.
Innovation Solution
A method is introduced to detect conflicts between terminal IDs and group IDs in D2D UE, whereupon a reallocation of terminal IDs is performed, and the new IDs are communicated to proximal or connected D2D UEs, ensuring smooth communication by using ID conflict indication mechanisms and reallocation protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If D2D UE uses terminal IDs for one-to-one communication and group IDs for one-to-many communication, then communication flexibility is improved, but ID conflict occurs when terminal ID equals group ID causing data packet misdirection
Solution Approach 1:
The patent introduces a conflict detection mechanism as an intermediary layer between ID assignment and data transmission. Before communication occurs, the system checks whether the terminal ID conflicts with any group ID. If a conflict is detected, the system prevents the problematic communication or adjusts the ID assignment, thereby avoiding data packet misdirection while maintaining communication flexibility.
Solution Approach 2:
The patent implements a feedback mechanism where D2D UE continuously monitors and reports ID conflicts to the network side. When a terminal ID is assigned, the system checks for conflicts with existing group IDs and provides feedback to adjust the assignment if necessary. This feedback loop ensures reliable data delivery while allowing flexible ID usage.
2Ease of manufacture
If D2D UE allocates terminal IDs independently without network coordination, then deployment simplicity is improved, but ID collision between different D2D UE occurs
Solution Approach 1:
The patent applies preliminary action by performing ID conflict checking before D2D communication is established. The network side pre-checks whether the terminal ID to be assigned conflicts with any group ID before allowing the D2D UE to proceed with communication. This preliminary verification ensures ID uniqueness without requiring complex real-time coordination during active communication.
Solution Approach 2:
The network side acts as an intermediary between D2D UE and ID assignment. Rather than allowing completely independent ID allocation, the network provides a conflict detection service that verifies ID uniqueness. This intermediary approach maintains deployment simplicity while preventing ID collisions.
3Device complexity
If D2D UE detects ID conflict by attempting data transmission, then detection simplicity is improved, but communication disruption occurs before conflict resolution
Solution Approach 1:
The patent implements preliminary action by performing ID conflict detection before data transmission begins. The conflict checking is performed in advance during the setup phase, allowing the system to resolve conflicts before they cause communication disruption. This ensures continuous communication while maintaining simple detection mechanisms.
Solution Approach 2:
The system uses feedback from the conflict detection phase to prevent communication disruption. When a potential conflict is detected during setup, the system provides feedback to adjust the ID assignment or communication parameters before actual data transmission occurs, thereby maintaining communication continuity.

AI summary
Published are a device-to-device identification conflict solution method and a D2D UE. The method comprises: a first D2D UE determining whether a terminal identification of the first D2D UE has a conflict with a terminal identification of another D2D UE or a D2D group identification; when the terminal identification of the first D2D UE has a conflict with the terminal identification of the other D2D UE or the D2D group identification, reallocating a terminal identification to the first D2D UE; and sending the terminal identification reallocated to the first D2D UE to a second D2D UE, wherein the second D2D UE is a D2D UE adjacent to the first D2D UE, or a D2D UE which has established a PC5 connection with the first D2D UE.
