QoS Flow Parameter Mapping for PDU Set Delay Budget Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices lack a method to determine whether to apply packet set delay budget (PSDB), packet set error rate (PSER), or packet set integrated handling information (PSIHI) at a protocol data unit set level, leading to unclear QoS parameter application in wireless communication systems.
Innovation Solution
Implementing methods and devices that enable determining whether to apply PSDB, PSER, or PSIHI by using various operations such as binding QoS flows to service flows or target rules, sending/receiving specific information, and determining the presence/absence of these parameters in context, thereby indicating their application or non-application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If PSDB, PSER, or PSIHI are made as optional QoS parameters for PDU set, then the flexibility of QoS parameter selection is improved, but the clarity of determining whether these parameters need to be applied deteriorates
Solution Approach 1:
The patent applies preliminary action by having the network side device send indication information in advance to the terminal device, clearly indicating whether PSDB, PSER, or PSIHI parameters should be applied. This preliminary indication resolves the ambiguity that would otherwise exist when these parameters are optional, allowing the terminal device to correctly configure and apply the appropriate QoS parameters before actual data transmission occurs.
2Measurement precision
If multiple QoS parameters (PSDB, PDB, AN PDSB, AN PDB) are applied at different levels (PDU set level and PDU level), then the precision of QoS control is improved, but the complexity of QoS management increases
Solution Approach 1:
The patent applies segmentation by clearly separating QoS parameter management into two distinct levels: PDU set level parameters (PSDB, PSER, PSIHI) and PDU level parameters (PDB, AN PDB). The indication information specifically identifies which level each parameter applies to, allowing the terminal device to manage these parameters independently at their respective levels without confusion, thereby maintaining precision while managing complexity through structured organization.
Solution Approach 2:
The patent applies local quality by allowing different QoS parameters to be applied to different locations or levels within the protocol stack. Specifically, PSDB and related parameters apply locally at the PDU set level, while PDB and AN PDB apply locally at the PDU level. This localized application of quality parameters enables precise control at each level without requiring uniform management across the entire system.
3Measurement precision
If indication information is sent to clearly specify whether PSDB should be applied, then the accuracy of parameter application is improved, but the signaling overhead increases
Solution Approach 1:
The patent applies the taking out principle by extracting the essential decision-making information (whether to apply PSDB, PSER, or PSIHI) from the complex QoS parameter set and encapsulating it in dedicated indication information. This extracted indication information is sent separately and clearly, allowing the terminal device to quickly determine parameter application without parsing through extensive QoS configurations, thereby achieving high accuracy with minimized signaling overhead.
