Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Synchronizing the switching of different wireless platforms across various frequency bands in real-time is challenging due to data loss, unnecessary pauses in data transmission, and unreliable synchronization caused by delays in message exchange through the host operating system.
Innovation Solution
Direct exchange of synchronization messages between wireless platforms to coordinate real-time switching, calculating a band switch time based on delay periods to minimize data loss and pause duration, and setting filters to operate on new frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless platforms switch frequency bands through host operating system message exchange, then switching can be performed, but data loss occurs and transmission pauses occur due to synchronization delays
Solution Approach 1:
The patent introduces a dedicated synchronization mechanism that acts as an intermediary between wireless platforms, bypassing the host operating system. This intermediary directly exchanges band switch notification messages between platforms, eliminating the delays and reliability issues caused by OS-level message passing while preventing data loss through coordinated switching timing
Solution Approach 2:
The patent implements preliminary action by having wireless platforms notify others of their intended band switches in advance. Before actually switching frequency bands, platforms send notification messages to other platforms, allowing them to prepare and coordinate their switching actions, thereby minimizing transmission pauses and preventing data loss
2Productivity
If wireless platforms switch frequency bands quickly to improve user experience, then transmission continuity improves, but data loss and synchronization errors increase
Solution Approach 1:
The patent implements feedback by having wireless platforms acknowledge received band switch notifications and confirm their switching status. This feedback mechanism ensures that all platforms are synchronized and have correctly processed switch commands, maintaining switching accuracy even when switching occurs rapidly to improve transmission continuity
Solution Approach 2:
The dedicated synchronization mechanism serves as an intermediary that manages the rapid switching process, coordinating between platforms to ensure data integrity is maintained even during quick frequency band transitions, thus preserving both productivity and reliability
3Adaptability or versatility
If multiple wireless platforms operate on different frequency band portions simultaneously, then frequency band utilization improves, but coordination complexity increases leading to synchronization failures
Solution Approach 1:
The patent applies segmentation by dividing the frequency band into distinct portions assigned to different wireless platforms. Each platform operates independently on its assigned portion, reducing coordination complexity while maintaining high frequency band utilization. The segmentation approach allows platforms to switch between segments without complex inter-platform coordination
Solution Approach 2:
The synchronization mechanism acts as an intermediary that manages the coordination between platforms operating on different frequency band portions. It handles the complexity of inter-platform coordination centrally, allowing individual platforms to operate independently on their assigned segments while maintaining overall system synchronization

AI summary
Disclosed herein are system, method, and computer program product embodiments for synchronizing the switching of different wireless platforms to different portions of a frequency band. An embodiment, at a first wireless platform, operates by receiving a band switch request message from a second wireless platform, wherein the band switch request message comprises a band switch delay period for the second wireless platform. The embodiment calculates a band switch time based on a band switch delay period for the first wireless platform and the band switch delay period for the second wireless platform. The embodiment transmits a band switch accept message comprising the band switch time to the second wireless platform. The embodiment sets a first filter to operate on a second portion of the frequency band based on the band switch time. The embodiment then operates on the second portion of the frequency band.
