V2X Identifier Update Timing via Dynamic Intervals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in determining the optimal time for updating identifiers, particularly in V2X communication networks, where secure and synchronized changes to Layer 2 group IDs are necessary to maintain privacy and prevent tracking of group members.
Innovation Solution
The method involves transmitting and receiving initial values and update intervals or one-time use values to determine the timing for updating identifiers, using a processor to synchronize these changes across network units and remote units, ensuring secure and encrypted application layer signaling to maintain privacy and prevent unauthorized tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identifiers are updated frequently to prevent tracking, then privacy protection is improved, but network synchronization complexity increases
Solution Approach 1:
The patent implements periodic identifier updates at predetermined intervals using counters that increment with each update cycle. This periodic mechanism ensures privacy protection through regular identifier changes while maintaining network synchronization through structured update timing, resolving the contradiction between frequent updates and synchronization complexity.
Solution Approach 2:
User equipment autonomously determines update timing based on received counter values and local timing mechanisms without requiring continuous network coordination. This self-service approach enables frequent identifier updates for privacy while reducing network synchronization complexity by eliminating the need for centralized update scheduling.
2Stability of the object's composition
If identifier updates are synchronized across all network units, then communication coordination is improved, but update timing precision requirements increase
Solution Approach 1:
The patent introduces counter values as intermediary parameters that mediate between network coordination requirements and local update execution. The counter serves as a synchronized reference that translates coordinated update decisions into precise local timing actions, improving communication coordination while managing timing precision requirements through this intermediary mechanism.
Solution Approach 2:
The network entity pre-configures counter values and update parameters before identifier updates occur. This preliminary action establishes the synchronization framework in advance, enabling coordinated identifier updates across network units without requiring high-precision real-time timing synchronization during the actual update process.
3Productivity
If update intervals are extended to reduce signaling overhead, then network efficiency is improved, but privacy protection effectiveness decreases
Solution Approach 1:
The patent implements dynamic update intervals where the counter value and update timing can be adjusted based on network conditions, privacy requirements, and service types. This dynamic mechanism allows the system to extend intervals for efficiency when appropriate while maintaining shorter intervals for enhanced privacy protection when needed, resolving the contradiction between network efficiency and privacy effectiveness.
