eUICC Provisioning Fallback via Activation Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eSIM provisioning methods face challenges such as hardcoding server addresses leading to activation stalls, reliance on out-of-service discovery servers, and high user complexity, resulting in user dissatisfaction and potential service disruptions.
Innovation Solution
A hybrid eSIM provisioning approach that dynamically switches from a server-based method to a user-initiated scanning process using activation codes when the discovery server fails, allowing seamless eSIM profile installation on diverse devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a server-based eSIM provisioning method is used, then automated profile installation is achieved, but service disruptions occur when discovery servers are out of service
Solution Approach 1:
The system dynamically switches between automated server-based provisioning and user-initiated activation code scanning based on the operational status of discovery servers. When servers are unavailable, the system transitions to the alternative method, ensuring continuous operation without service disruptions.
Solution Approach 2:
The provisioning approach changes parameters from fully automated server-based operation to user-initiated activation based on server availability conditions. This parameter change allows the system to adapt to different operational states and maintain reliability.
2Device complexity
If discovery servers are relied upon for eSIM provisioning, then centralized control is maintained, but activation stalls when servers are unavailable
Solution Approach 1:
Activation codes serve as an intermediary mechanism that bridges the gap between centralized server control and user-initiated activation. The codes contain embedded server addresses and profile identifiers, allowing users to initiate provisioning without real-time server availability while maintaining centralized control over the actual profile installation process.
3Ease of operation
If manual intervention is required for eSIM activation, then user control is increased, but user complexity and dissatisfaction increase
Solution Approach 1:
Users scan activation codes using their device cameras and automatically complete the provisioning process without requiring manual server selection or complex configuration. The system handles profile download and installation automatically after the user initiates the process through scanning, combining user control with automated execution to reduce complexity.
4Productivity
If hardcoding server addresses is used, then provisioning speed is improved, but adaptability to different devices and brands is reduced
Solution Approach 1:
Activation codes are designed to be universally compatible across different device types, brands, and models. Each code contains device-agnostic information (server addresses, profile identifiers) that allows the same provisioning mechanism to work across diverse hardware platforms, eliminating the need for device-specific hardcoding while maintaining fast provisioning speeds.

AI summary
A method of provisioning an eUICC of a mobile communication device. The method comprises sending a GSMA confirm order request from an eUICC provisioning application executing on a computer system to a SM-DP+ server, wherein the confirm order comprises an ICCID and a FQDN of a discovery server; in response to receiving a GSMA confirm order response indicating a failure of the discovery server, determining by the eUICC provisioning application that a mobile communication device associated with the ICCID is configured with an LPA application that is able to complete an alternative eSIM profile provisioning process using a scanning device to capture an activation code; generating an activation code by the eUICC provisioning application that encodes an address of the SM-DP+ server and the ICCID; and sending the activation code by the eUICC provisioning application to an email account associated with a user of the mobile communication device.
