RAN Charging Correction for Dropped PDU Set QoS Packets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack accurate charging mechanisms for service data streams with high bandwidth, low latency, and high reliability requirements, leading to inaccurate charging results due to actively dropped packets.
Innovation Solution
A charging correction method where a radio access network (RAN) entity sends usage data information indicating dropped packets in a packet data unit (PDU) set based quality of service (QoS) handling procedure to a network function, enabling improved charging accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packets are actively dropped in PDU set based QoS handling procedure, then QoS requirements (bandwidth, latency, reliability) can be met, but charging accuracy deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the RAN entity reports usage data information about dropped packets to the network function. This feedback loop allows the charging system to receive information about packets that were dropped due to QoS handling, enabling the network function to correct charging calculations and achieve accurate charging while maintaining QoS requirements.
2Measurement precision
If usage data information for dropped packets is reported to network function, then charging accuracy is improved, but device complexity increases
Solution Approach 1:
The patent segments the charging correction process into distinct functional components: the RAN entity responsible for packet handling and usage data collection, and the network function responsible for receiving usage data and performing charging correction. This segmentation allows each component to focus on its specific task, reducing overall system complexity while improving charging accuracy.

AI summary
A charging correction method, performed by a radio access network (RAN) entity, includes: sending usage data information for a charging correction to a network function, where the usage data information indicates packets dropped by the RAN entity in a packet data unit (PDU) set based quality of service (QoS) handling procedure, and where the network function is a first network function or a second network function.
