Vehicle Telematics SIM Profile Switching for Secure Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle telematics systems face challenges in efficiently managing data flows between consumer and vehicle-centric services, particularly in determining when to switch between SIM profiles to ensure secure and uninterrupted delivery of vehicle updates without impacting consumer services or incurring additional data charges.
Innovation Solution
A method and system that utilize a management platform to determine the appropriate SIM profile for data flows, allowing vehicle-centric services to be downloaded using a vehicle SIM profile only when the vehicle is in a key-off condition or when high-security/critical updates are required, thereby separating consumer and vehicle-centric data flows and ensuring secure, uninterrupted service delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle-centric services data is downloaded using a consumer SIM profile, then consumer services can be maintained, but security and reliability of vehicle updates are compromised
Solution Approach 1:
The patent segments the SIM profile usage into two distinct modes: consumer SIM profile for consumer services and vehicle SIM profile for vehicle-centric services. This segmentation allows each service type to use the appropriate SIM profile, ensuring that vehicle updates maintain high security while consumer services continue uninterrupted.
2Productivity
If vehicle-centric services data is downloaded when the vehicle is in key-on condition, then service delivery is faster, but consumer services may be impacted and additional data charges may be incurred
Solution Approach 1:
The patent implements dynamic SIM profile switching based on vehicle operational state. When the vehicle is in key-off condition, the system uses the vehicle SIM profile for downloading vehicle-centric services data. When the vehicle is in key-on condition and consumer services are active, the system switches to consumer SIM profile, thereby adapting to changing conditions to avoid data charges and service disruption.
3Device complexity
If a single SIM profile is used for both consumer and vehicle-centric services, then device complexity is reduced, but data flow management becomes inefficient
Solution Approach 1:
The system implements self-service through automatic SIM profile selection based on the type of data flow required. The mobile device automatically determines whether to use the consumer SIM profile or vehicle SIM profile based on whether the incoming data is consumer-centric or vehicle-centric, eliminating the need for manual intervention while optimizing data flow efficiency.

AI summary
A computer device, having at least two long-range wireless profiles and coupled with a communication bus of a vehicle, receives a notice that a vehicle-centric download for the computer device, or for a vehicle device coupled to the communication bus, is pending from a remote server. The vehicle computer device determines the size and security requirement associated with the pending download, and a current operational state of the vehicle. If the size or security requirement is low, a consumer-centric profile may be used for the download even if the vehicle is currently being used. If the download file size is large or requires very high security, or if a user is currently using the computer device according to the consumer-centric profile, the computer device may schedule the download to occur after receiving a trigger event occurrence message.
