Bootstrap eSIM Onboarding for Zero-Touch Managed WWAN Provisioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of provisioning an embedded subscriber identity module (eSIM) for wireless wide area network (WWAN) access in managed client information handling systems is burdensome and time-consuming, requiring multiple steps before and after eSIM provisioning, which increases deployment costs and time.
Innovation Solution
A pre-loaded temporary bootstrap eSIM profile enables a temporary out-of-band (OOB) WWAN access to establish a restricted and temporary bootstrapped link with a remote IT management server, allowing automatic notification and onboarding of the system, followed by a seamless transition to a regular access eSIM profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional eSIM provisioning process is used, then complete WWAN access provisioning is achieved, but deployment time and complexity increase significantly
Solution Approach 1:
The system pre-loads a temporary bootstrap eSIM profile into the eUICC before device deployment. This preliminary action enables the device to immediately establish WWAN connectivity upon first boot without waiting for post-deployment provisioning steps, thereby reducing deployment time while ensuring complete provisioning capability
Solution Approach 2:
The provisioning process is segmented into two distinct phases: (1) immediate temporary bootstrap phase using a pre-loaded restricted eSIM profile for initial WWAN access and onboarding, and (2) subsequent permanent provisioning phase where the temporary profile is replaced with a full permanent eSIM profile. This segmentation allows the device to achieve functional connectivity quickly while completing full provisioning in stages
2Reliability
If traditional eSIM provisioning process is used, then complete WWAN access provisioning is achieved, but deployment cost increases
Solution Approach 1:
The temporary bootstrap eSIM profile is pre-loaded during manufacturing, eliminating the need for complex post-deployment provisioning infrastructure and reducing deployment operational costs. The preliminary configuration enables automated onboarding processes that reduce manual intervention requirements
Solution Approach 2:
The temporary bootstrap eSIM profile acts as an intermediary that facilitates initial device onboarding and WWAN connectivity establishment. This intermediary profile enables the device to communicate with provisioning servers and complete authentication workflows before being replaced by the permanent profile, thereby simplifying the overall provisioning architecture
3Reliability
If user interaction is required for eSIM provisioning, then proper authentication and configuration can be verified, but deployment friction increases
Solution Approach 1:
The device performs self-service provisioning by automatically utilizing the pre-loaded temporary bootstrap eSIM profile to establish WWAN connectivity and initiate onboarding workflows without requiring user intervention. The system autonomously completes authentication with provisioning servers and manages the transition to permanent profile, thereby eliminating deployment friction while maintaining security through automated verification protocols

AI summary
A method of onboarding provisioning of a managed client information handling system, comprising a hardware processor executing code instructions of an endpoint onboarding agent to detecting a powering up process and automatically establish a first restricted bootstrap wireless wide-area network (WWAN) wireless link using a stored temporary provisional bootstrap embedded subscriber identity module (eSIM), identifying the managed client information handling system via the first restricted bootstrap WWAN wireless link to a remote information technology (IT) management server to trigger a second regular access WWAN wireless link for the managed client information handling system, provisioning a regular access eSIM profile to access the second regular access WWAN wireless link, and upon verified login credentials at an enterprise identity provider, downloading designated software applications for onboarding installation on the managed client information handling system.
