Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The overhead caused by headers in voice packets transmitted in non-terrestrial networks is significant, leading to low transmission efficiency and reliability.
Innovation Solution
A method for aggregating multiple packets into a single aggregated packet based on configuration information received from a base station, which includes generating and transmitting aggregated packets in non-terrestrial networks, reducing header overhead and improving transmission efficiency and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voice packets are transmitted individually with headers, then each packet can be transmitted independently, but the header overhead becomes significant and transmission efficiency decreases
Solution Approach 1:
The patent applies packet aggregation technology to combine multiple voice packets into a single aggregated packet for transmission. This merging approach reduces the number of separate transmission operations, thereby reducing total header overhead and improving transmission efficiency while maintaining reliability through proper error handling mechanisms.
2Productivity
If packet aggregation is implemented, then header overhead is reduced and transmission efficiency improves, but the complexity of packet processing increases
Solution Approach 1:
The patent implements preliminary actions by pre-configuring aggregation parameters and establishing aggregation groups before actual packet transmission. This allows the system to prepare aggregation structures in advance, reducing the complexity burden during real-time packet processing while still achieving the benefits of aggregated transmission.
3Loss of energy
If multiple packets are aggregated into one, then the number of transmissions is reduced, but the time to transmit all packets increases due to aggregation duration
Solution Approach 1:
The patent applies dynamic aggregation strategies where the aggregation duration and packet grouping are adjusted based on real-time network conditions, traffic patterns, and channel quality. This dynamic approach optimizes the balance between transmission time and energy consumption by adapting aggregation parameters to current system state rather than using fixed aggregation schemes.
