Wireless Relay Charging via Dual Identity Sets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in UE-to-UE communication scenarios with relays, there is a lack of effective management and reporting of user information and charging due to the absence of central node management and distributed generation of UE information, leading to complexities in charging and privacy concerns, particularly in sidelink communications where ID updates are frequent and network cannot accurately acquire updated identities.
Innovation Solution
A method and device for wireless communications that utilize a first ID and a second ID in the MAC header of data blocks to clearly indicate the generator or receiver, enabling accurate charging information generation and reporting, even in scenarios with frequent ID updates, by using the destination or source ID fields to identify nodes involved in data transmission or reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distributed generation of UE information is used in relay scenarios, then system flexibility and privacy are improved, but charging management complexity increases and information accuracy deteriorates
Solution Approach 1:
The charging information is segmented into multiple components: first charging information generated by the relay node containing first ID and data volume, and second charging information generated by the network side containing second ID and corrected data volume. This segmentation allows distributed generation while maintaining centralized management capability.
Solution Approach 2:
The network side acts as an intermediary that receives charging information from the relay node, verifies the identity relationships between first ID and second ID, and generates corrected charging information. This intermediary mechanism resolves the conflict between distributed generation and centralized management.
2Loss of time
If relay nodes generate charging information locally, then response time is improved, but information accuracy and consistency worsen
Solution Approach 1:
The network side provides feedback by verifying the identity relationships between first ID and second ID, and by generating corrected charging information when discrepancies are found. This feedback mechanism ensures accuracy while maintaining the relay node's local generation capability for timely response.
Solution Approach 2:
The relay node performs preliminary charging information generation locally based on available data, which provides timely response. The network side then performs preliminary verification of identity relationships before finalizing the charging information, ensuring accuracy without delaying the overall process.
3Reliability
If frequent ID updates are implemented, then security and privacy are improved, but charging information tracking complexity increases
Solution Approach 1:
The network side serves as an intermediary that manages ID updates by verifying the relationship between first ID (in charging information) and second ID (actual user identity). This intermediary mechanism handles the complexity of frequent ID updates while allowing the relay node to maintain simple local charging information generation.
