Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In heterogeneous wireless networks, terminals face challenges in efficiently distributing data traffic across multiple networks with different communication schemes, Quality of Service (QoS), bandwidth, and time delays, leading to congestion on specific networks and inefficient utilization of available resources.
Innovation Solution
A terminal and network apparatus share a data transmission rule to divide and transmit data across multiple wireless networks, selecting appropriate networks based on service characteristics, QoS, and network conditions, ensuring data is recomposed correctly and distributed efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted through a single wireless network, then transmission simplicity is maintained, but network congestion occurs and resource utilization is inefficient
Solution Approach 1:
The patent segments data into multiple data groups and transmits them through different wireless networks simultaneously. The terminal device divides original data into first data groups, second data groups, and third data groups, which are then transmitted through first, second, and third wireless networks respectively. This segmentation approach distributes traffic load across multiple networks, improving resource utilization efficiency while maintaining manageable transmission complexity through systematic data division and routing.
2Productivity
If data is distributively transmitted across multiple networks, then resource utilization improves, but data recomposition complexity increases
Solution Approach 1:
The patent applies preliminary action by having the terminal device perform data segmentation and embed routing information before transmission. The terminal divides data into groups and assigns each group to specific networks in advance, including identification information that indicates the original data sequence. This preliminary organization simplifies the recomposition process at the receiving end, as the network device can directly reassemble data groups based on the embedded identification information without complex processing.
3Manufacturing precision
If a data transmission rule is shared between terminal and network apparatus, then data recomposition accuracy improves, but communication overhead increases
Solution Approach 1:
The patent implements copying by having the terminal device generate and transmit a copy of the data transmission rule to the network device. The terminal creates a data transmission rule that includes segmentation criteria and identification information mapping, then transmits this rule as separate information to the network device. This copied rule enables the network device to accurately recompose data without requiring continuous complex communication, as both devices operate with identical recomposition logic. The overhead is minimized by transmitting the rule once rather than continuously.
