UE Ranging Authorization Exchange for Secure Direct Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security mechanisms in wireless communication systems fail to prevent misbehaving third-party User Equipments (UEs) from requesting unauthorized ranging results from target UEs, as they lack a method to verify the authorization of the third-party UE.
Innovation Solution
A method involving the exchange of identification information and ranging service codes through request and response messages between UEs and network nodes to authorize direct connection transmissions, ensuring only authorized UEs can acquire ranging results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the current security mechanism is used to allow third-party UE to call ranging service with assistant UE, then the ranging service can be accessed by third-party UE, but the security is insufficient to prevent unauthorized UE from requesting ranging results of target UE
Solution Approach 1:
The patent applies preliminary action by performing authorization verification before allowing the third-party UE to access the ranging results. The assistant UE checks whether the third-party UE is authorized to request the ranging result of the target UE before proceeding with the ranging operation, thus preventing unauthorized access in advance
Solution Approach 2:
The patent implements feedback by introducing an authorization check mechanism where the assistant UE receives authorization information from the target UE and uses this feedback to determine whether to allow the third-party UE to access the ranging results. This creates a closed-loop security verification process

AI summary
An information processing method is performed by a first User Equipment (UE), and includes: sending a first request message to a second UE, wherein the first request message is configured to request a direct connection transmission between the first UE and the second UE, and the first request message includes third identification information of a third UE for requesting a ranging result.
