Privacy Configuration Verification via Relay UE When Target Connection Fails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a core network element cannot establish a connection to a target UE, existing technologies fail to complete privacy configuration verification for positioning services.
Innovation Solution
Implement indirect communication via a second UE that establishes a connection to the target UE, allowing the access and mobility management AMF to receive privacy configuration verification results through the second UE, thereby completing verification and enhancing system compatibility and universality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the core network element directly establishes a connection to the target UE for privacy configuration verification, then the verification process is simple and direct, but the verification cannot be completed when the target UE is disconnected or cannot be connected to the network
Solution Approach 1:
The patent introduces a relay UE as an intermediary device that establishes a connection between the core network element and the target UE. The relay UE receives positioning service requests from the core network element, performs privacy configuration verification with the target UE, and forwards the verification results back to the core network element. This intermediary mechanism enables reliable privacy verification even when the target UE is disconnected or cannot directly connect to the network.
2Adaptability or versatility
If indirect communication via a relay UE is implemented for privacy verification, then verification can be completed when direct connection fails, but the communication process becomes more complex
Solution Approach 1:
The relay UE is designed with multi-functionality to handle various positioning service scenarios. It can perform privacy configuration verification, forward positioning service requests and responses, and adapt to different network conditions. This universal design enables the relay UE to handle both direct connection cases and indirect connection cases, improving system adaptability without requiring separate specialized mechanisms for each scenario.
3Reliability
If the AMF sends positioning service requests through a relay UE, then privacy verification can be completed for disconnected target UEs, but additional network elements and communication steps are required
Solution Approach 1:
The system performs preliminary actions by pre-establishing relay UE connections and pre-configuring privacy verification parameters before the actual positioning service is needed. The relay UE is pre-positioned and ready to perform verification, and the necessary communication protocols and data structures are pre-configured. This preliminary preparation reduces the overhead during actual verification operations and improves overall processing efficiency.
