Vehicle Message Transmission via Dynamic SIM Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motor vehicles often lack the necessary software modules for messaging services, and manufacturers face challenges in communicating with drivers or owners due to data protection constraints, limiting direct communication and efficient message transmission regardless of software or mobile radio status.
Innovation Solution
A method and system that activate inactive subscriber identity modules and manage software installation on motor vehicles to ensure messages can be transmitted and displayed, using pre-defined selection criteria and data connections through a central computer, allowing for efficient use of transmission capacity and user confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software modules are not installed or are terminated on motor vehicles, then device complexity is reduced and data protection is improved, but the ability to transmit and display messages is lost
Solution Approach 1:
The system performs preliminary actions by activating the SIM card before message transmission is needed, and by pre-establishing the data connection infrastructure. The central computer can activate SIM cards in advance for vehicles that may need messaging capabilities, ensuring that when a message needs to be sent, the communication pathway is already prepared and functional.
2Ease of operation
If direct communication with buyers is implemented, then message transmission capability is improved, but data protection constraints are violated
Solution Approach 1:
The patent introduces a central computer as an intermediary between the manufacturer and the buyer's vehicle. This intermediary system manages SIM card activation, handles message routing, and coordinates communication without requiring direct manufacturer access to buyer data. The system uses vehicle identification numbers and mobile radio identification numbers as indirect identifiers, allowing communication while respecting data protection boundaries.
3Adaptability or versatility
If SIM cards are activated for all vehicles, then message transmission capability is improved, but use of energy and transmission capacity is wasted
Solution Approach 1:
The system dynamically activates SIM cards based on actual communication needs rather than maintaining permanent activation. The central computer can activate SIM cards on-demand for specific vehicles that need to receive messages, and deactivate them afterward. This dynamic approach ensures that transmission resources are only consumed when necessary, adapting the system's communication capability to actual requirements.
4Productivity
If software modules are terminated to free resources, then productivity is improved, but the ability to process and display messages is lost
Solution Approach 1:
The patent extracts the messaging functionality from permanent software installations by using a separate, on-demand SIM card-based communication layer. Instead of relying on permanently installed messaging software that consumes resources, the system uses a minimal communication stack that activates only when needed, with message processing capabilities being temporarily invoked rather than continuously running.

AI summary
A method for transmitting a message to be displayed to a display device of a motor vehicle includes the steps of: is selecting at least one motor vehicle to which a message is to be transmitted from a motor vehicle database on a central computer using predetermined selection criteria and ascertaining a mobile radio system mobile radio identification number associated with the respective motor vehicle; activating an inactive subscriber identity module of the mobile radio system using the mobile radio identification number, wherein the subscriber identity module is connected to a radio device of the at least one selected motor vehicle; setting up a data link from the central computer to the radio device of the at least one selected motor vehicle via the mobile radio system; transmitting the message to be displayed from the central computer via the data link to a processor apparatus, connected to the radio device, of the respective ascertained motor vehicle; processing the message further by way of the processor apparatus and displaying the message on a display device connected to the processor apparatus.
