Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications, default marking of packet data units (PDU) sets and data bursts leads to resource waste and unnecessary bandwidth occupation when marked information is not required.
Innovation Solution
A method and apparatus for selectively marking data packets with PDU Set or Data Burst information based on the capabilities and requirements of communication devices, allowing devices to indicate support or non-support for these operations, and performing marking operations only when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If default marking of PDU Set information and Data Burst information is performed on all data packets, then comprehensive information availability is improved, but resource waste and bandwidth occupation increase
Solution Approach 1:
The patent changes the marking parameter from a fixed default state to a dynamic state based on device capability parameters. Devices indicate their support for PDU Set information-based operations and Data Burst information-based operations through capability indication messages, allowing the marking behavior to adapt to each device's specific parameters rather than applying a universal default marking approach.
Solution Approach 2:
The patent implements partial marking by selectively applying marking operations only to data packets that require it, based on the receiving device's capabilities. Instead of performing excessive marking on all packets, the system performs marking only when the device supports and requires it, thereby reducing unnecessary resource consumption while maintaining information availability where needed.
2Loss of information
If marking operations are performed on all data packets regardless of requirement, then information completeness is improved, but bandwidth occupation increases
Solution Approach 1:
The system changes the bandwidth usage parameter by dynamically adjusting marking behavior based on device capability parameters. Through capability indication messages, devices communicate their support for specific information types, allowing the network to optimize bandwidth occupation by applying marking only where required rather than universally.
Solution Approach 2:
The patent applies partial marking by performing marking operations only on data packets destined for devices that support and require such information. This selective approach ensures information completeness for capable devices while reducing bandwidth occupation by avoiding unnecessary marking on packets for devices that do not support these features.
3Loss of energy
If selective marking based on device capabilities is implemented, then resource efficiency is improved, but device complexity increases
Solution Approach 1:
The patent reduces device complexity during operation by performing preliminary capability indication before actual data transmission. Devices exchange capability information in advance through indication messages, allowing both transmitting and receiving devices to pre-determine marking requirements without complex real-time decisions during data packet processing.
Solution Approach 2:
The system implements feedback through capability indication messages where devices communicate their support for PDU Set information-based operations and Data Burst information-based operations. This feedback mechanism allows the network to adapt marking behavior based on actual device capabilities, achieving resource efficiency through information exchange rather than complex processing logic.
4Measurement precision
If capability indication messages are exchanged between devices, then marking accuracy is improved, but communication overhead increases
Solution Approach 1:
The patent reduces communication overhead by performing capability indication as a preliminary action during connection establishment or configuration phases. By determining marking requirements in advance through capability exchange messages, the system avoids repeated capability queries during data transmission, thereby minimizing ongoing communication overhead while maintaining marking accuracy.
Solution Approach 2:
The capability indication messages serve multiple functions: they indicate support for PDU Set information-based operations, support for Data Burst information-based operations, and enable subsequent marking decisions. This multi-functionality reduces the need for separate signaling messages, thereby minimizing communication overhead while achieving accurate marking based on device capabilities.
