Vehicle Data Transmission via Broadcast and WLAN Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transmitting data in vehicles often incur high costs due to mobile phone connections, and there is a need for efficient and cost-effective data transmission solutions that minimize data costs.
Innovation Solution
A method that determines whether desired data is available from a second source free of cellular connection costs, utilizing radio or WLAN access points for cost-effective transmission, and storing broadcast data for future playback based on user profiles and popularity analysis, with error correction mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is transmitted via mobile communication connection, then data can be requested and received on demand, but transmission costs increase
Solution Approach 1:
The system dynamically switches between mobile communication connection and broadcast/WLAN connection based on data availability. It first checks if data is available via free broadcast or WLAN sources, and only uses mobile communication when necessary, thereby optimizing cost while maintaining on-demand functionality
Solution Approach 2:
The system introduces an intermediary checking mechanism that determines data availability from free sources (broadcast/WLAN) before initiating costly mobile communication transmission. This intermediary step prevents unnecessary mobile data usage while preserving on-demand access capability
2Loss of energy
If broadcast sources are used for data transmission, then transmission costs decrease, but data cannot be explicitly requested
Solution Approach 1:
The system performs preliminary actions by proactively checking data availability from broadcast and WLAN sources before attempting mobile communication transmission. It pre-determines whether free sources can satisfy the data request, eliminating the need for explicit on-demand requests via costly mobile connections
Solution Approach 2:
The system automatically checks multiple data sources and selects the most cost-effective option without requiring user intervention. It self-services by determining data availability from broadcast/WLAN sources and autonomously deciding whether to use free or paid transmission channels
3Reliability
If data is stored locally for future playback, then data availability increases, but storage space is consumed
Solution Approach 1:
The system applies local quality by selectively caching only frequently requested or popular data locally, while leaving less frequently accessed data on remote servers. This targeted local storage approach maximizes data availability for likely requests while minimizing unnecessary storage space consumption

AI summary
The invention relates to a method for transmitting data for use in a vehicle, which involves – a user request for the transmission and reproduction of desired data (DAT) from a first source (Q1) by means of a mobile radio link (MV) being taken as a basis for ascertaining whether the desired data (DAT) are also provided by a second source (Q2) independently of the mobile radio link (MV), – the desired data (DAT) being received in the vehicle from the second source (Q2) for reproduction for a user if the desired data (DAT) are also provided by the second source (Q2) independently of the mobile radio link (MV).
