Vehicle Communication Profile Provision via Centralized Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of temporarily used vehicles, such as those in car-sharing fleets, face difficulties in using their own communication profiles due to the inconvenience or impossibility of managing separate login credentials for each vehicle, which hinders seamless connectivity.
Innovation Solution
A method and system that enables a central unit to manage and provide communication profiles, allowing users to load and activate their profiles remotely via an authentication with a communication service provider, bypassing the need for separate logins with vehicle managers, using eSIM technology and centralized authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users use their own communication profile in a temporarily used vehicle, then connectivity is enabled, but the complexity of managing separate login credentials for each vehicle increases
Solution Approach 1:
The patent introduces a backend system as an intermediary between the user and the vehicle's communication module. The backend receives authentication data from the user device, manages the communication profile deployment, and coordinates with the vehicle system. This mediator handles the complex authentication and profile management processes, freeing the user from direct interaction with multiple login systems while enabling connectivity.
2Reliability
If separate login credentials are required for each vehicle, then security is improved, but user-friendliness deteriorates
Solution Approach 1:
The patent implements a universal authentication approach where a single user device can authenticate across multiple vehicles through the backend system. Instead of requiring separate credentials for each vehicle, the system uses a universal authentication mechanism that works across the entire fleet. The backend manages vehicle-specific security requirements while presenting a unified, user-friendly interface to the end user.
3Ease of operation
If communication profile deployment is automated via backend, then ease of operation is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring and storing communication profiles in the backend before they are needed. When a user authenticates, the system has already prepared the necessary profile data and can quickly deploy it to the vehicle without requiring complex real-time processing. This advance preparation simplifies the user experience while managing system complexity through structured pre-computation.
4Adaptability or versatility
If users without manager account can use communication function, then adaptability is improved, but authorization control becomes more difficult
Solution Approach 1:
The backend serves as an intermediary authorization layer that handles access control for users without direct manager accounts. The system receives authentication requests from any user device, verifies credentials through the communication service provider, and manages profile deployment without requiring the user to have a pre-existing account with the vehicle manager. This intermediary layer maintains secure authorization control while enabling broad accessibility.

AI summary
A method for providing a communication function in a means of transport includes receiving, in a central unit of a communication service provider in which identification information of a user is stored, a request from the user to use a communication profile in the means of transport. The method also includes receiving, in a central unit of a manager of the means of transport, a request from the central unit of the communication service provider to provide the communication profile in the means of transport. The method further includes enabling provision of the communication profile for the means of transport by the central unit of the manager of the means of transport.
