Centralized Communication Profile Management via Secure-Element Gateway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication profile management mechanisms, particularly in vehicles, are inadequate for managing and updating telecommunication profiles due to the dual possibility of locating the entity LPA in the operating system or secure element, leading to service quality concerns and after-sales support issues for automobile manufacturers.
Innovation Solution
A centralized communication profile management device and process that relocates profile management functions to the network, using a communication agent as a gateway, enabling remote management of secure elements through a centralised device with secure protocols and authentication mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entity LPA is located in the operating system or secure element of the terminal, then profile management can be performed locally, but this causes problems with managing, using, and updating the entity LPA, as well as problems with managing profiles
Solution Approach 1:
The patent extracts the LPA entity from the terminal (either OS or secure element) and relocates it to a remote server. The LPA functionality is now provided as a service over the network, eliminating the complexity of managing LPA within the terminal while preserving profile management capabilities.
Solution Approach 2:
The patent introduces a communication agent as an intermediary component that remains in the terminal to facilitate communication between the secure element and the remote LPA service. This mediator handles the complexity of LPA management centrally while maintaining local profile operations.
2Adaptability or versatility
If the user manages telecommunication profiles directly in the terminal, then profile installation and activation can be performed, but automobile manufacturers must provide after-sales service for service quality problems
Solution Approach 1:
The patent extracts profile management control from the end user and transfers it to the automobile manufacturer through the remote LPA service. The manufacturer can now remotely manage and update profiles, ensuring service quality while maintaining profile management flexibility through centralized control.
Solution Approach 2:
The patent enables the automobile manufacturer to receive feedback about profile usage and service quality through the centralized LPA service, allowing them to proactively manage profiles and address issues before they affect users, thereby improving service quality assurance.
3Ease of operation
If profile management is performed locally in the terminal, then user control over profiles is maintained, but remote management and updates cannot be efficiently performed
Solution Approach 1:
The patent introduces a communication agent as an intermediary that allows the secure element to communicate with the remote LPA service. This enables efficient remote management and updates while preserving user control capabilities through the standardized interface provided by the communication agent.
Solution Approach 2:
The patent makes the LPA service universally accessible through the network, allowing both local user control and remote manufacturer management to coexist. The standardized communication interface supports multiple functions including profile installation, activation, deactivation, and updates.

AI summary
A profile management device is provided. The device comprises a profile management module capable of dynamically creating and executing an execution task to respond to a need for remote management of a communication profile in a secure element embedded in a terminal; a communication module capable of setting up a first communications channel between the execution task and a communication profile manager; the execution task being capable of obtaining the communication profile from the manager via the first communications channel; the communication module being capable of setting up a communications session between the execution task and a communication agent configured to send to the secure element, at least one management command of the profile encapsulated in at least one message sent by the execution task in terms of the session; and a module configured to delete the execution task when an action responding to the need has been performed.
