Solution Overview

Problem

Conventional communication systems waste transmission resources by applying the same set of PDU set QoS parameters to all PDU sets within a QoS flow, despite varying transmission quality requirements among them.

Innovation Solution

Implement a method where different PDU sets within a QoS flow are assigned distinct PDU set QoS parameters based on their specific transmission requirements, allowing for improved control accuracy and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the same set of PDU set QoS parameters is applied to all PDU sets within a QoS flow, then the system complexity is reduced and ease of operation is improved, but transmission resources are wasted due to inability to tailor parameters to individual PDU set needs

Engineering Contradiction:
Improveease of operationVSAvoidtransmission resource waste
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The patent segments the QoS parameter application by introducing PDU set identification information that allows different PDU sets within the same QoS flow to be individually identified and assigned different PDU set QoS parameters. This segmentation enables fine-grained control where each PDU set can have customized parameters matching its specific transmission requirements, thereby reducing transmission resource waste while maintaining manageable system complexity through automated parameter assignment based on PDU set identification.

Inventive Principle:
Principle #1Segmentation

2Reliability

If different PDU set QoS parameters are assigned to different PDU sets, then transmission quality is improved and resource efficiency increases, but device complexity and control complexity increase

Engineering Contradiction:
Improvetransmission qualityVSAvoidcontrol complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-assigning PDU set QoS parameters to different PDU sets based on their identification information before transmission occurs. The network device receives PDU sets with embedded identification information, automatically retrieves or determines the appropriate QoS parameters for each identified PDU set, and applies them in advance. This preliminary parameter assignment reduces real-time control complexity while ensuring each PDU set receives optimized parameters for its specific requirements, thereby improving transmission quality without proportionally increasing device complexity.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If PDU set QoS parameters are customized for individual PDU sets, then transmission flexibility and control accuracy are improved, but the complexity of parameter management and system configuration increases

Engineering Contradiction:
Improvetransmission flexibilityVSAvoidparameter management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by enabling PDU sets to carry their own identification information that automatically links them to appropriate QoS parameters. When a PDU set is transmitted, its embedded identification information serves as a key that allows the network device to automatically retrieve and apply the correct customized parameters without manual configuration or complex management overhead. This self-identifying mechanism provides high transmission flexibility for different PDU set types while keeping parameter management complexity low through automated parameter selection based on PDU set self-identification.

Inventive Principle:
Principle #25Self-service

AI summary

This application relates to a communication method and apparatus. A first network element receives a first message from a second network element, where the first message includes first information, the first information indicates a first mapping relationship between a first parameter and first transmission requirement information, the first parameter indicates a first attribute of a first PDU set, the first transmission requirement information indicates a percentage of a first quantity in a total quantity of PDUs included in the first PDU set, and the first quantity is a quantity of PDUs that need to be correctly transmitted by the first network element during transmission of the first PDU set. The first network element transmits the first PDU set based on the first transmission requirement information. In this application, different PDU set QoS parameters may be set for different PDU sets, to improve control accuracy and transmission flexibility, so that transmission quality can be ensured, and a waste of transmission resources can be reduced.
