Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle data systems face challenges in maintaining reliable wireless connectivity due to gaps in network coverage, which can lead to data loss and increased costs, especially when using satellite networks for coverage in unpopulated areas.
Innovation Solution
The system employs a link detection component to assess end-to-end connectivity across multiple wireless carriers, switching between cellular and satellite networks based on performance and cost thresholds, utilizing the Tiny Telemetry Transport Protocol (T3P) over UDP/IP to ensure continuous data transmission and minimize data loss.

Engineering Contradiction Analysis
1Area of stationary object
If satellite networks are used for coverage in unpopulated areas, then network coverage is improved, but cost increases
Solution Approach 1:
The system dynamically switches between satellite and cellular networks based on real-time performance measures and cost thresholds. The mobile gateway can adaptively select which network to use for data transmission, transitioning from static network selection to dynamic adaptation, thereby optimizing both coverage and cost.
Solution Approach 2:
The system changes operational parameters by selecting different wireless carriers based on performance metrics and cost considerations. It monitors data session performance, latency, and cost thresholds, then switches networks when parameters indicate suboptimal performance or excessive cost, effectively changing the network parameter to resolve the contradiction.
2Reliability
If network switching is implemented to maintain connectivity, then reliability is improved, but data loss may occur during transitions
Solution Approach 1:
The system performs preliminary actions by establishing performance monitoring and threshold evaluation before switching networks. It continuously assesses data session performance and predicts when switching may be beneficial, taking preventive measures to maintain connectivity rather than reacting after data loss occurs.
Solution Approach 2:
The system implements feedback mechanisms by monitoring data session performance, latency, and cost thresholds in real-time. This feedback loop enables the mobile gateway to make informed switching decisions, adjusting network selection based on continuous performance evaluation to minimize data loss while maintaining reliability.
3Reliability
If performance monitoring is continuously performed, then connectivity reliability is improved, but system complexity increases
Solution Approach 1:
The system achieves multi-functionality by combining performance monitoring, cost evaluation, and network switching capabilities within the mobile gateway. This universal approach allows a single component to handle multiple functions (monitoring, decision-making, switching) rather than requiring separate systems, thereby improving reliability without proportionally increasing complexity.

AI summary
A first performance measure is determined of an existing data session between a mobile gateway and a cloud gateway via a first wireless carrier. Second performance measures of others of the wireless carriers are determined during the existing data session. Based on the first performance measure and the second performance measures, the existing data session is continued with the cloud gateway via a second of the wireless carriers.
