Adaptive Packet Marking for PDU Sets and Data Bursts
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
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
