RAN Node Radio Resource Allocation for V2X Ranging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in providing accurate and efficient location services, particularly in vehicle-to-everything (V2X) ranging based positioning, where existing technologies struggle to manage radio resources effectively and ensure user privacy in vehicle location determination.
Innovation Solution
The proposed solution involves a network architecture that supports ranging based location services, where a radio access network (RAN) node allocates radio resources and uses internal and external IDs to manage V2X positioning, ensuring privacy by isolating radio-specific resource management from the core network and utilizing network slicing for V2X-specific functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing wireless communication systems are used for V2X ranging based positioning, then basic location services can be provided, but accurate and efficient location determination cannot be achieved due to ineffective radio resource management and insufficient privacy protection
Solution Approach 1:
The patent segments the network architecture into RAN node and core network components, with the RAN node specifically responsible for radio resource management and internal ID allocation. This segmentation allows specialized handling of positioning tasks at the RAN level while maintaining core network functionality, thereby improving location accuracy without overwhelming system complexity
Solution Approach 2:
The patent introduces an intermediary mechanism where the RAN node manages radio resources and allocates internal IDs independently, acting as a mediator between the core network and positioning operations. This intermediary approach enables efficient radio resource management at the edge while preserving core network simplicity and enhancing user privacy through internal ID isolation
2Reliability
If existing wireless communication systems are used for V2X ranging based positioning, then basic location services can be provided, but user privacy cannot be adequately protected in vehicle location determination
Solution Approach 1:
The patent extracts the radio resource management function from the core network and places it at the RAN node level. By taking out this functionality, the core network no longer needs to handle detailed radio resource allocation and internal ID management, thereby simplifying the core network architecture while enhancing user privacy through localized ID management at the RAN node
Solution Approach 2:
The RAN node serves as an intermediary that manages internal IDs and radio resources independently, creating a privacy boundary between the core network and positioning operations. This intermediary structure protects user privacy by keeping identifying information localized at the RAN node rather than exposing it to the core network, while maintaining network architecture manageability
3Productivity
If radio resources are allocated for ranging operations in existing systems, then positioning can be performed, but efficient resource management and isolation of sensitive information cannot be achieved
Solution Approach 1:
The patent segments information management by introducing internal IDs that are scoped at the RAN node level. This segmentation isolates sensitive positioning information within the RAN node's internal ID space, preventing its exposure to the core network while maintaining efficient radio resource allocation and management capabilities
Solution Approach 2:
The RAN node acts as an intermediary that manages internal IDs and radio resources locally, creating an information barrier that prevents sensitive data from reaching the core network. This intermediary mechanism enables efficient resource management at the edge while protecting sensitive information through localized ID handling, eliminating the need for complex information isolation mechanisms elsewhere in the network

AI summary
A network architecture is disclosed with support for location services (LCS). A radio access network (RAN) node receives a registration request from a user equipment (UE), indicating that the UE supports a ranging based location service session. The RAN node farther receives an internal identifier (ID) for identifying information associated with the UE in communication between the RAN node and a core network during the ranging based location service session. The RAN node allocates radio resources to the UE for performing a ranging operation involving a plurality of devices including the UE, and associates the radio resources with the internal ID of the UE for identifying location results. Then the RAN node informs the UE of the radio resources allocated for the ranging operation.
