Handover Buffer Delay Adjustment for Packet Loss Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing buffer adjustments during handover processes, leading to potential packet loss and disruption due to inadequate delay management in handover transitions.
Innovation Solution
The proposed solution involves adjusting the delay used by a buffer based on indications of handover occurrence, such as sensor inputs or machine learning model outputs, to process packets effectively during and after handover, using mechanisms like radio resource control modules to provide handover start or end indications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If buffer delay is increased to prevent packet loss during handover, then reliability of data transmission is improved, but transmission latency increases
Solution Approach 1:
The buffer delay parameter is made dynamic rather than static. The system adjusts the buffer delay value based on handover detection status - increasing delay when handover is detected to prevent packet loss, and reducing delay during normal operation to minimize latency. This dynamic adjustment resolves the contradiction by adapting the delay parameter to different operational states.
Solution Approach 2:
The patent changes the buffer delay parameter value based on handover conditions. When a handover is detected, the system modifies the delay parameter to a higher value to ensure packets are not lost during the transition. This parameter change allows the system to prioritize reliability during handover while maintaining lower latency during stable connections.
2Stability of the object's composition
If buffer delay is adjusted dynamically during handover, then stability of data transmission is improved, but device complexity increases
Solution Approach 1:
The system implements a feedback mechanism where handover detection triggers buffer delay adjustment. The handover detection module monitors for handover conditions and provides feedback to the buffer management module, which then adjusts the delay parameter accordingly. This feedback loop maintains transmission stability during handover without requiring complex manual intervention or overly sophisticated algorithms.
Solution Approach 2:
The buffer management system automatically adjusts its own delay parameter based on handover detection, without requiring external control or complex coordination. The system serves itself by detecting handover conditions and autonomously modifying buffer behavior, thereby improving stability while keeping the control mechanism relatively simple.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify an indication of an occurrence of a handover. The UE may adjust a delay used by a buffer based at least in part on the indication of the occurrence of the handover. The UE may process one or more packets of the buffer based at least in part on the adjustment of the delay used by the buffer. Numerous other aspects are described.
