Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems for vehicles lack convenience in service provision, particularly in managing communication states and detecting abnormalities, leading to inconsistencies and inefficiencies in service delivery.
Innovation Solution
A wireless communication system comprising a database and two communication processing elements that manage mobile terminal and vehicle information, enabling seamless state transitions, authentication, and abnormality detection, allowing for efficient start and stop of communication services using an in-vehicle device as a base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication service is provided for mobile terminal in vehicle, then user convenience is improved, but service management complexity and reliability deteriorate due to lack of proper state detection and abnormality monitoring
Solution Approach 1:
The patent implements feedback mechanisms where the first communication processing element continuously monitors mobile terminal states (on/off, communication status) and reports to the server, which then manages the in-vehicle device accordingly. This closed-loop feedback system ensures reliable service management while maintaining user convenience through automated state detection and response.
Solution Approach 2:
The patent introduces a server as an intermediary between the mobile terminal and the in-vehicle device. The server receives state information from the first communication processing element, processes authentication and service management logic, and controls the second communication processing element. This intermediary architecture separates concerns, improving reliability while maintaining ease of operation.
2Reliability
If authentication and service control are implemented, then service reliability is improved, but communication processing time and system complexity increase
Solution Approach 1:
The patent performs preliminary actions by having the first communication processing element detect mobile terminal states and report to the server in advance before service is needed. The server pre-processes authentication information and prepares service delivery, reducing actual service start time while maintaining reliability through advance state management.

AI summary
In response to a vehicle being switched from an IGN OFF state (non-operating state) to an IGN ON state (operating state) in a state in which a mobile terminal has been activated, the use of wireless communication (Wi-Fi communication) by the mobile terminal via a network using an in-vehicle device as a base station can be started. In response to the vehicle being switched from the IGN ON state (operating state) to the IGN OFF state (non-operating state) in the state in which the mobile terminal has been activated, the use of wireless communication (Wi-Fi communication) by the mobile terminal via the network using the in-vehicle device as the base station is stopped.
