Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems often experience delays due to limited speed and bandwidth, particularly when user equipment (UE) devices need to transmit data through slower wireless networks.
Innovation Solution
A communications system that utilizes a dual-network approach, where UE devices transmit data over a faster terrestrial network when available, and switch to a slower space-based network by segmenting data and transmitting it in real-time as the user provides input, ensuring continuous data transmission and minimizing wait times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted over a slower wireless network, then network availability is maintained, but transmission time increases excessively
Solution Approach 1:
The patent segments data transmission into two phases: initial transmission over the faster terrestrial network when available, and subsequent transmission over the slower space-based network when terrestrial network is unavailable. This segmentation allows the system to utilize the faster network for critical initial data transfer, reducing overall transmission time while maintaining reliability through fallback to the slower network.
Solution Approach 2:
The system dynamically switches between terrestrial and space-based networks based on real-time network availability and performance conditions. The UE device monitors network conditions and adjusts transmission parameters accordingly, transitioning from segmented transmission mode to non-segmented transmission mode when terrestrial network becomes available, thereby optimizing transmission time while maintaining network availability.
2Loss of time
If segmented data transmission is used over a slower network, then user wait time is reduced, but network complexity increases
Solution Approach 1:
The patent implements segmentation at the data transmission level, dividing the data stream into segments that can be transmitted asynchronously over the slower space-based network. This allows the UE device to transmit segments in parallel and reduces user wait time by not requiring sequential completion of all data transmission, while the core network handles the reassembly complexity centrally.
Solution Approach 2:
The core network acts as an intermediary that receives segmented data from the UE device over the space-based network, stores the segments, and reconstructs the complete data stream for delivery to the recipient device. This intermediary approach shifts the complexity of segment management and reassembly from the UE device to the core network, reducing device complexity while maintaining reduced user wait time.
3Productivity
If real-time transmission begins before user input completion, then transmission efficiency improves, but data accuracy may be compromised
Solution Approach 1:
The patent applies preliminary action by initiating data transmission over the space-based network before the user completes all input, particularly for non-critical data segments. The UE device transmits segments as they become available during user input, rather than waiting for complete input formation. This improves transmission efficiency by utilizing available network capacity, while data accuracy is maintained through subsequent validation and correction mechanisms.
Solution Approach 2:
The system implements feedback mechanisms where the UE device monitors user input completion status and network transmission status, adjusting transmission parameters accordingly. When user input is completed or modified, the system receives feedback and updates the transmission accordingly, ensuring data accuracy while maintaining high transmission efficiency through continuous operation.

AI summary
A communications system may include user equipment (UE) that transmits data to a recipient via a network. The UE may receive user input and may generate the data based on the input. When a terrestrial network is unavailable to the UE, the UE may transmit segments of the data over a satellite constellation as the UE continues to receive input and while connectivity to the constellation exceeds a threshold. If a portion of the input includes an edit to a previous segment, the UE may include an edit flag in the corresponding segment. Once input has finished, the UE may sign the segments and may transmit a signature over the constellation. The network may store the segments as received from the constellation, may replace edited segments with more recent segments containing edit flags, and may compile and transmit all of the segments to the recipient upon receipt of the signature.
