Ranging Service Authorization Using Decode Key Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in controlling access to ranging services, especially in licensed spectrum, as UEs may operate out of network coverage, leading to unauthorized access and interference.
Innovation Solution
A method where a UE receives a registration message with a decode key for a ranging service, validates an identifier from another UE using the decode key, and establishes a ranging session, allowing controlled access to ranging services even when out of coverage by exchanging and validating encoded values and identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UEs are allowed to access ranging services without network coverage, then service availability is improved, but unauthorized access and interference increase
Solution Approach 1:
The network node performs preliminary authorization by providing UEs with encoded values and identifiers before the UEs operate out of coverage. This advance preparation enables UEs to validate each other's credentials independently, ensuring authorized access while maintaining service availability without network coverage.
Solution Approach 2:
Encoded values and identifiers act as intermediaries that carry authorization information between UEs and the network node. These credentials enable UEs to authenticate each other without direct network involvement, resolving the contradiction between service availability and unauthorized access prevention.
2Adaptability or versatility
If UEs validate identifiers using decode keys independently, then network coverage dependency is reduced, but device complexity increases
Solution Approach 1:
UEs are equipped with the capability to independently validate identifiers using decode keys without requiring continuous network assistance. This self-service approach enables UEs to autonomously determine authorization status, reducing network coverage dependency while the complexity is managed through standardized validation procedures.
3Object-affected harmful factors
If authorization control is maintained in licensed spectrum, then interference is reduced, but access flexibility is limited
Solution Approach 1:
Authorization credentials are distributed in advance before UEs need to access ranging services. This preliminary authorization maintains control over who can access the licensed spectrum while allowing UEs the flexibility to operate independently once authorized, reducing interference while preserving access flexibility.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive a registration message including a decode key associated with a ranging service. The UE may receive, from a second UE, an encoded value and an identifier associated with the second UE. The UE may validate the identifier using the encoded value and the decode key. The UE may establish a ranging session associated with the second UE based at least in part on validating the identifier. Numerous other aspects are described.
