Dynamic PDU Set Discarding Control for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network technologies face challenges in dynamically managing protocol data unit (PDU) set discarding, particularly in congested networks, which can lead to inefficient radio resource utilization and degrade user experience due to excessive packet loss and compression.
Innovation Solution
Implementing dynamic control of PDU set discarding based on network congestion status, where the network dynamically activates or deactivates PDU set discarding states at user equipment (UE) by configuring PDU set discarding states and using media access control (MAC) control elements to switch between discarding states, considering factors like PDU importance and threshold levels.

Engineering Contradiction Analysis
1Productivity
If PDU set discarding is implemented to manage network congestion, then radio resource utilization is improved, but packet loss increases
Solution Approach 1:
The patent implements dynamic control of PDU set discarding by switching between different discarding states (first and second states) based on network congestion conditions. The network device dynamically determines which state to use, allowing the system to adapt to changing network conditions and optimize the balance between resource utilization and packet loss.
Solution Approach 2:
The patent changes the parameter of PDU set discarding behavior by implementing multiple discarding states with different characteristics. The first state uses stricter discarding criteria while the second state uses more lenient criteria, allowing the system to adjust the discarding parameter based on network conditions to balance resource efficiency and delivery reliability.
2Ease of operation
If dynamic control of PDU set discarding is implemented, then user experience is improved, but device complexity increases
Solution Approach 1:
The patent introduces a MAC control element as an intermediary mechanism to manage the complexity of dynamic PDU set discarding control. This control element serves as a standardized interface between the network device and the user equipment, simplifying the implementation of dynamic discarding control while maintaining user experience quality.
Solution Approach 2:
The patent makes the MAC control element universal by using it for multiple purposes: both for activating PDU set discarding and for switching between different discarding states. This multi-functionality reduces the overall complexity by consolidating control mechanisms into a single standardized element.
