Concurrent eSIM Profile and Digital Content Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process of switching carrier services for communication devices with embedded subscriber identity modules (eSIMs) is time-consuming and inconvenient, especially for machine-to-machine (M2M) devices in IoT solutions, due to the sequential downloading and installation of eSIM profiles and non-eSIM digital content.
Innovation Solution
A method and system that enables at least partially concurrent implementation of eSIM profiles and non-eSIM device-specific digital content, allowing communication devices to switch carriers by downloading and installing both simultaneously, using a local profile assistant application to manage the process and communicate with carrier and OEM servers for configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If sequential downloading and installation of eSIM profile and non-eSIM digital content is used, then installation reliability is maintained, but configuration time is excessive
Solution Approach 1:
The patent segments the configuration process into two independent parallel tasks: (1) downloading and installing the eSIM profile, and (2) downloading and installing non-eSIM digital content. These tasks are executed concurrently rather than sequentially, allowing the system to reduce total configuration time while maintaining the reliability of each individual task through separate error handling and installation procedures.
2Productivity
If concurrent implementation of eSIM profile and non-eSIM digital content is used, then configuration time is reduced, but process complexity increases
Solution Approach 1:
The patent introduces a profile manager as an intermediary component that coordinates the concurrent execution of eSIM profile installation and non-eSIM digital content installation. The profile manager handles task scheduling, monitors download progress, manages installation sequences, and handles error recovery, thereby abstracting the complexity of concurrent operations from the rest of the system while enabling parallel processing to improve configuration speed.
3Ease of operation
If sequential installation process is used, then error handling is simplified, but user convenience deteriorates
Solution Approach 1:
The patent implements a self-service error handling mechanism where the profile manager autonomously monitors the concurrent installation processes, detects errors in either the eSIM profile or non-eSIM content installation, and automatically initiates appropriate recovery actions such as retrying downloads, isolating failed components, or notifying the user. This self-service approach improves user convenience by eliminating manual intervention while containing error handling complexity within the profile manager module.

AI summary
A communication device, method and computer program product support concurrently receiving an embedded subscriber identity module (eSIM) profile and non-eSIM digital content from separate servers to enable service from a selected carrier. The communication device receives carrier destination data. The communication device requests download of the eSIM profile associated with a selected carrier from a subscription or carrier server based on the identified carrier destination. The communication device receives, via the network interface, digital content associated with the selected carrier and a configuration of the communication device from a configuration manager hosted on a configuration server. The digital content enables functionality via the selected carrier. The communication device installs the eSIM profile in the eSIM.
