eSIM Profile Provisioning Using Device Capability Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to address the issue of device-specific eSIM profile provisioning, leading to device-incompatible profiles being installed, causing errors such as periodic boot-up failures and un-initialization of applications.
Innovation Solution
A wireless device provides additional device capabilities information to a network-based provisioning server, enabling it to select and install device-compatible eSIM profiles, and mitigate device-incompatible profiles by disabling or re-enabling bootstrap profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If eSIM profiles are provisioned without feature-dependent compatibility checking, then provisioning speed is improved, but device compatibility and service reliability deteriorate
Solution Approach 1:
The patent performs compatibility checking between device capabilities and eSIM profile requirements before the provisioning process begins. The network device obtains capability information from the wireless device and checks whether the device supports required features (such as NAI, NSI, GLI, GCI, non-3GPP applications) before downloading the eSIM profile. This preliminary action prevents incompatible profiles from being provisioned, ensuring reliability without sacrificing provisioning speed.
2Reliability
If comprehensive feature compatibility checking is implemented, then device compatibility is improved, but provisioning complexity increases
Solution Approach 1:
The patent introduces a network device (SM-DP+) as an intermediary that manages the complex compatibility checking process. The wireless device simply provides its capability information to the network device, which then performs the comprehensive feature matching against eSIM profile requirements. This intermediary approach allows thorough compatibility verification without burdening the wireless device with complex checking logic, thus improving feature compatibility while managing provisioning complexity centrally.
3Measurement precision
If device capability information is collected and processed, then profile selection accuracy is improved, but information processing overhead increases
Solution Approach 1:
The patent extracts only the essential capability information needed for compatibility checking from the wireless device. The network device obtains specific feature support indicators (such as whether the device supports NAI, NSI, GLI, GCI, or non-3GPP applications) without requiring comprehensive device telemetry. This extracted information is sufficient for accurate profile selection while minimizing information processing overhead and avoiding unnecessary data collection.

AI summary
This application describes techniques for dynamic feature-dependent electronic subscriber identity module (eSIM) profile provisioning for wireless devices, including provisioning of device-compatible eSIM profiles and mitigation of provisioned device-incompatible eSIM profiles. A wireless device can provide information regarding additional device capabilities indicating support (or lack thereof) for optional cellular wireless standard features to a provisioning server, which can select an eSIM profile matched to the wireless device. In some cases, a wireless device detects an error condition resulting from enabling a device-incompatible eSIM profile on an embedded universal circuit card (eUICC) of the wireless device, disables the errant eSIM profile, and notifies a provisioning server regarding the error condition. The provisioning server can account for the device compatibility when providing additional eSIM profiles to the wireless device.
