Mobile Router Data Upload via Cellular Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices within vehicles face mobility constraints when trying to connect to wireless networks, especially when the vehicle is in motion, as they typically require proximity to wireless access points, limiting their effective range and usability.
Innovation Solution
A wireless mobile router is provided in a vehicle, capable of establishing communication links with a network management system, collecting and storing data independently, and uploading it upon predetermined events, while maintaining connectivity through cellular networks, even when the vehicle is in motion, and automatically reestablishing data transmission if interrupted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile devices use wireless LAN access points for connectivity, then they can connect to wired networks, but their mobility is constrained by the requirement to stay within wireless communication range
Solution Approach 1:
The patent introduces a cellular network as an intermediary between the mobile device and the wired network. The mobile device connects to the cellular network, which in turn provides connectivity to the wired network through the access point. This intermediary cellular network allows the device to maintain connectivity while moving freely without being constrained by the line-of-sight requirement of direct wireless LAN connections.
Solution Approach 2:
The patent segments the network connectivity path into two independent parts: a wireless cellular network connection for mobile communication and a wired network connection for data transmission. By separating these functions, the system allows the mobile device to use cellular networks for connectivity while the access point handles wired network access, eliminating the constraint that the device must stay within wireless range of the access point.
2Adaptability or versatility
If mobile devices are disposed within a vehicle that is in motion, then they can access networks, but the mobility constraining problem is aggravated due to changing positions relative to access points
Solution Approach 1:
The cellular network serves as a stable intermediary that does not depend on the vehicle's position relative to fixed access points. As the vehicle moves, the cellular network maintains continuous coverage through its own distributed infrastructure, providing reliable connectivity without the connection instability that occurs when vehicles pass by or move relative to fixed wireless access points.
3Adaptability or versatility
If most mobile computer devices do not have cellular network interfaces, then they cannot directly use cellular networks, but this limits their ability to maintain connectivity in motion
Solution Approach 1:
The patent implements a universal connectivity solution where the mobile device can use either a wireless LAN interface or a cellular network interface to maintain connectivity. The system is designed to work with devices that have cellular interfaces directly, and also accommodates devices without cellular interfaces by using the cellular network as an intermediary through the access point, thereby maintaining connectivity productivity across diverse device types.

AI summary
A method comprises: providing a wireless mobile router in a vehicle. The mobile router is operable to establish a communication link to a network management system. The mobile router collects data independent of the router being coupled to the network management system; stores the data in the router; establishes a first communication link between the router and the network management system upon an occurrence of a first predetermined event; operates the router to upload the data to the network management system upon occurrence of the first predetermined event; and transmits the data to the network management system via the first communication link.
