eSIM Profile Selection via Local Profile Assistant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eSIM profile management systems incur roaming charges and may not provide optimal network performance when users travel to areas not covered by their primary mobile network operator, as they often rely on traditional roaming methods which are costly and lack seamless network transitions.
Innovation Solution
A Local Profile Assistant (LPA) application on user devices is enabled to download and activate new eSIM profiles from preferred RSP platforms as users move into new geographical areas, allowing seamless connectivity with partner mobile network operators without roaming, using an eSIM management platform that provides lists of RSP platforms optimized for different regions based on service features like availability and response time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional roaming methods are used for eSIM profile management, then network connectivity is maintained in new geographical areas, but roaming charges are incurred and network performance is not optimized
Solution Approach 1:
The system segments the eSIM profile management by separating the home RSP platform from local RSP platforms in different geographical areas. The LPA application can selectively download profiles from local RSP platforms when roaming, avoiding traditional roaming charges while maintaining connectivity through local network profiles.
Solution Approach 2:
The LPA application acts as an intermediary between the user device and multiple RSP platforms. It receives a list of preferred RSP platforms from the home MNO and can automatically select and download profiles from appropriate local platforms, mediating between connectivity needs and cost optimization.
2Productivity
If eSIM profiles are manually managed, then security and control are maintained, but seamless network transitions and automated optimization are not achieved
Solution Approach 1:
The LPA application provides self-service functionality by automatically monitoring geographical location, selecting appropriate RSP platforms from the provided list, and downloading necessary eSIM profiles without user intervention. This automates network transitions while maintaining security through pre-approved platform lists.
Solution Approach 2:
The home MNO pre-provides a list of preferred RSP platforms for different geographical areas before the user travels. This preliminary action enables the LPA application to make informed decisions about profile downloads, achieving automated optimization without real-time complex analysis.
3Adaptability or versatility
If multiple RSP platforms are supported for different regions, then network performance and availability are optimized, but system complexity and platform selection difficulty increase
Solution Approach 1:
The system implements local quality by providing region-specific RSP platform lists tailored to different geographical areas. The LPA application automatically selects the appropriate local platform based on current location, ensuring optimal network performance without requiring users to understand or choose from multiple platforms manually.
Data Source
AI summary
Telecommunication services are received at a user device using an embedded subscriber identity module (eSIM) profile stored on the user device while the user device is located in a first geographical area. A list of preferred remote SIM provisioning (RSP) platforms that provide eSIM profiles specific to a partner MNO of the MNO in a second geographical area is also received from an eSIM management platform of an MNO; The user device is then determined to have moved to a second geographical area based on a geolocation of the user device. Subsequently, an additional eSIM profile specific to the partner MNO of the MNO is downloaded to the user device from an RSP platform of one or more RSP platforms included in the list of preferred RSP platforms.
