Solution Overview
Problem
In areas with poor communication network coverage, mobile devices face connectivity issues due to limited network availability and high costs, especially when a mobile device is not associated with a motor vehicle, and existing solutions do not efficiently manage communication connections between mobile devices and communication networks.
Innovation Solution
A communication system with a detector to identify geographical regions of need, utilizing motor vehicles equipped with both wireless interfaces for mobile devices and communication networks, and a management device to control and switch communication connections dynamically, allowing mobile devices to access resources through multiple motor vehicles while optimizing energy use and network bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile device uses a direct connection to the communication network, then connection quality is good in covered areas, but connection fails or quality deteriorates in areas with poor coverage
Solution Approach 1:
The patent introduces a motor vehicle as an intermediary communication node between the mobile device and the communication network. The vehicle equipped with wireless interface acts as a mediator that relays communication signals, enabling connectivity in areas where direct network access is poor or unavailable.
Solution Approach 2:
The communication path is segmented into multiple hops: mobile device to motor vehicle, and motor vehicle to communication network. This segmentation allows the system to bypass areas of poor direct coverage by using the vehicle as an intermediate relay point.
2Reliability
If a motor vehicle shares its communication connection with an external mobile device, then connectivity is enabled in low-coverage areas, but data security risks and billing complexity increase
Solution Approach 1:
The system implements self-service mechanisms where the mobile device and motor vehicle autonomously negotiate connection parameters, authentication, and billing terms through automated protocols, reducing the need for manual intervention and simplifying management complexity.
Solution Approach 2:
The system incorporates feedback loops for authentication, authorization, and billing verification between the mobile device, motor vehicle, and network management system, ensuring secure and controlled sharing of communication resources.
3Speed
If the motor vehicle moves relative to the mobile device, then mobility is maintained, but the communication connection breaks off
Solution Approach 1:
The system dynamically adapts the communication connection to accommodate vehicle movement. The wireless interface and connection management are designed to maintain connectivity despite relative motion, adjusting transmission parameters and handover timing as needed.
Solution Approach 2:
The system performs preliminary actions by establishing connection handover protocols before the vehicle moves out of range. The mobile device and vehicle negotiate and prepare for connection transfer in advance, ensuring seamless continuity during movement.
4Productivity
If multiple wireless devices attempt to communicate in a small space, then network utilization increases, but connection quality and reliability decrease
Solution Approach 1:
The patent segments the communication traffic by routing it through the motor vehicle's wireless interface rather than through congested direct network access points. This segmentation distributes the load and reduces interference in crowded spectral environments.
Data Source
AI summary
A communication system includes a detector for detecting a geo-graphical region in which there is a need for communication; at least one motor vehicle having a first wireless interface for coupling to a mobile device in the area of the motor vehicle and a second wireless interface for coupling to a communication network; and a management device. The management device is designed to control the motor vehicle in order to make a communication connection in the determined region between a mobile device in the region and a resource connected to the communication network.
