Solution Overview

Problem

Existing wireless communication protocols require default marking of packet data units (PDU Sets) and data bursts, leading to resource waste and unnecessary bandwidth occupation when marking is not required.

Innovation Solution

A flexible information marking method that allows communication devices to selectively indicate support or non-support for PDU Set and Data Burst operations, enabling dynamic marking based on specific requirements and configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If default marking of PDU Set information and Data Burst information is performed, then protocol compliance and information tracking are ensured, but resource overhead and bandwidth occupation increase unnecessarily

Engineering Contradiction:
Improveprotocol complianceVSAvoidresource overhead
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements dynamic marking by introducing capability indication mechanisms where devices advertise their PDU Set and Data Burst support capabilities. The network then adaptively applies marking only to devices that support it, transforming the static default-marking approach into a dynamic, condition-based system that optimizes resource usage while maintaining protocol compliance for supporting devices

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the marking parameter from a fixed default state to a variable state based on device capability. By introducing capability indication parameters and conditional marking parameters, the system transitions from universal marking to selective marking, reducing resource overhead for devices that do not require marking while maintaining it for devices that do

Inventive Principle:
Principle #35Parameter changes

2Loss of information

If marking is applied to all PDU Sets and Data Bursts, then information tracking is maintained, but bandwidth occupation increases due to unnecessary marking

Engineering Contradiction:
Improveinformation trackingVSAvoidbandwidth occupation
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent applies local quality by making marking applicable only to specific devices based on their capability. Instead of uniformly marking all PDU Sets and Data Bursts across the network, the system applies marking locally to only those devices that have indicated support for PDU Set and Data Burst operations, thereby reducing overall bandwidth occupation while maintaining information tracking where needed

Inventive Principle:
Principle #3Local quality

3Loss of energy

If flexible selective marking is implemented, then resource overhead is reduced, but system complexity increases due to capability indication and conditional marking logic

Engineering Contradiction:
Improveresource overheadVSAvoidmarking control logic
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by having devices indicate their PDU Set and Data Burst support capabilities in advance through capability indication messages. This pre-announcement of capabilities allows the network to make informed marking decisions without requiring complex real-time analysis, simplifying the overall system logic while achieving resource optimization

Inventive Principle:
Principle #10Preliminary action
