Wireless Communication Path Control for Reduced Handover Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The movement of a wireless terminal can cause delays in communication due to the need to establish a new communication path, as existing solutions require the completion of a new path formation before communication can start.
Innovation Solution
A wireless communication system and method that includes end wireless devices, transfer devices, and a transfer management device, which receives communication status information and executes a transfer route control process to control paths between transfer devices, allowing the switching process to begin before the new path is fully formed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a new path is added in the transfer device network before communication starts, then communication reliability is improved, but communication delay increases
Solution Approach 1:
The transfer management device receives communication status information and executes transfer route control processes in advance before the switching process is completed. This preliminary action allows the new path to be prepared beforehand, so that when the switching completes, communication can immediately use the new path without waiting for path formation, thus reducing communication delay while maintaining reliability
Solution Approach 2:
The system uses communication status information as feedback to trigger transfer route control processes. By monitoring the switching process status and receiving communication status information, the transfer management device can dynamically adjust path formation timing, initiating path setup at the optimal moment rather than strictly before or after switching, thereby balancing reliability and delay
2Stability of the object's composition
If the path formation is completed before communication starts, then communication stability is improved, but communication speed deteriorates
Solution Approach 1:
The system performs preliminary path formation based on received communication status information, but allows this process to overlap with the switching process rather than completing it entirely beforehand. This enables the path to be ready or nearly ready when switching completes, maintaining stability while reducing the idle time that slows down communication initiation
Solution Approach 2:
The transfer management device dynamically adjusts the path formation process based on real-time communication status information. Rather than using a fixed timing approach, the system adapts the path formation schedule to the actual switching progress, allowing flexible coordination between path setup and communication start, thus improving both stability and speed
