Off-line eSIM Profile Provisioning for Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for provisioning eSIM profiles for wireless devices often require a real-time data connection, leading to delayed initial setup and a suboptimal user experience. Additionally, preloading profiles before assembly can result in outdated profiles and limited customization options.
Innovation Solution
A phased approach for off-line eSIM profile provisioning, where bootstrap and fully functional eSIM profiles are pre-generated and encrypted by MNO provisioning servers, stored securely on BPP aggregator servers, and then downloaded to the eUICC during device assembly or testing, without the need for an active data connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If eSIM profiles are downloaded in real-time after device purchase, then profile customization and user choice are improved, but setup time is increased and user experience is degraded
Solution Approach 1:
The patent pre-generates and pre-encrypts eSIM profiles on the BPP aggregator server before the device is even assembled. This preliminary action allows profiles to be ready for immediate download during device assembly or testing, eliminating the need for post-purchase setup delays while maintaining profile customization options.
2Loss of time
If eSIM profiles are preloaded to eUICC before assembly, then setup time is reduced, but profile outdatedness and lack of customization are worsened
Solution Approach 1:
The system performs preliminary encryption and preparation of profiles on the BPP aggregator server, but the actual profile download to eUICC occurs at the optimal time during device assembly or testing. This timing allows profiles to be current and customized while still enabling fast setup without post-purchase delays.
Solution Approach 2:
The BPP aggregator server acts as an intermediary between the MNO provisioning servers and the device manufacturing process. It receives profile requests, generates and encrypts profiles, stores them securely, and makes them available for download during device assembly, bridging the gap between early profile preparation and late customization needs.
3Reliability
If profile provisioning requires active data connection, then security and real-time updates are improved, but setup process complexity and user experience are worsened
Solution Approach 1:
All security-critical operations including profile generation, encryption, and authentication are performed in advance on the secure BPP aggregator server before the device needs to connect to cellular networks. This preliminary secure setup eliminates the need for active data connections during initial device configuration, simplifying the user experience while maintaining security.
Solution Approach 2:
The system enables self-service profile provisioning during device assembly or testing by automatically downloading pre-generated profiles from the BPP aggregator server without requiring user intervention or external data connections. The device configures itself with appropriate profiles during manufacturing, making the process easier for end users.

AI summary
This application describes a phased approach to provision eSIM profiles to a wireless device. Credentials are preloaded to an eUICC during manufacture of the eUICC and used subsequently to load eSIM profiles to the eUICC without requiring an active, real-time connection to an MNO provisioning server. Multiple bound profile packages (BPPs) can be pre-generated and encrypted by MNO provisioning servers for an eUICC and transferred to a BPP aggregator server before assembly of the eUICC in a respective wireless device. A local provisioning server in a manufacturing facility mutually authenticates and connects to the BPP aggregator server to download and store one or more of the encrypted BPPs for later installation on the eUICC. The local provisioning server subsequently mutually authenticates and connects to the eUICC to load at least one of the one or more pre-generated, encrypted BPPs to the eUICC during assembly and/or testing of the wireless device.
