Wireless Download Switching for Timeout Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional divided download methods in wireless communication suffer from reduced efficiency due to data loss when communication quality deteriorates, leading to timeouts and incomplete downloads, as they discard non-continuous data sections during resumed downloads.
Innovation Solution
A wireless communication apparatus that switches from a divided download process using multiple threads to an ordinary download process using a single thread when communication quality deterioration is detected, ensuring completion before a timeout by measuring communication quality and throughput, and controlling the download process to resume with continuous data sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the divided download method is used to download data by dividing it into sections while using multiple threads, then the download speed is improved and communication resources are efficiently utilized, but when communication quality deteriorates, data is discarded and download efficiency decreases
Solution Approach 1:
The patent applies dynamics by making the download method adaptable and changeable based on communication conditions. The system dynamically switches between divided download method (when communication quality is good) and ordinary download method (when communication quality deteriorates), allowing the download process to adjust its behavior according to real-time network conditions, thus resolving the contradiction between high speed and reliability
Solution Approach 2:
The patent changes the parameter of download method selection based on communication quality measurements. By monitoring communication quality parameters and adjusting the download approach accordingly, the system optimizes both download speed and completion rate, preventing data loss while maintaining efficient resource utilization
2Productivity
If the divided download method is used, then communication resources are efficiently utilized by downloading divided sections simultaneously, but when timeout occurs due to communication quality deterioration, non-continuous data sections are discarded causing lower efficiency
Solution Approach 1:
The patent implements feedback by continuously measuring communication quality during the download process and using this information to control the download method. When communication quality deteriorates, the system receives feedback and switches from divided download to ordinary download, preventing data loss while maintaining resource efficiency
Solution Approach 2:
The system dynamically adjusts the download approach based on real-time communication conditions, transitioning from a static divided download method to a flexible approach that can switch between divided and ordinary download methods, thereby preventing data loss while maintaining resource utilization efficiency
3Reliability
If the ordinary download method is used to resume download after timeout by continuing from the downloaded position, then data is not discarded, but the download speed is lower compared to divided download method
Solution Approach 1:
The patent changes the download method parameter based on communication quality conditions. By switching between divided download (for speed) and ordinary download (for reliability) based on measured communication parameters, the system achieves both fast download when possible and reliable completion when necessary

AI summary
A wireless communication apparatus according to an embodiment includes: a communicating unit that performs one selected from between a first download process that downloads data through a wireless communication by dividing the data into sections while using a plurality of threads and a second download process that downloads the data while using a single thread; a measuring unit that measures communication quality of the wireless communication; a judging unit that, when a deterioration in the communication quality is measured during the first download process, judges whether or not it is possible to complete the download in all of the plurality of threads before a timeout; and a controlling unit that, when it is determined to be impossible to complete the download in all of the plurality of threads before the timeout, switches the first download process into the second download process.
