Subscription Profile Creation via Device Capability Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating subscription profiles for eUICCs and other subscriber entities are complex and prone to errors, particularly when the mobile network operator (MNO) lacks information about the device capabilities, leading to potential incompatibilities.
Innovation Solution
A subscription provisioning server that obtains capability information from the subscriber entity and uses this information to create a subscription profile, thereby enabling automatic selection of the best-suited profile type based on provided information, reducing the need for manual allocation and minimizing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual profile allocation is used by MNO, then profile creation can be performed, but errors occur due to incorrect device capability information and incompatibility issues
Solution Approach 1:
The subscriber entity autonomously provides accurate capability information to the SM-DP+ server during profile download initiation. This self-service approach eliminates the need for manual intervention by the MNO in gathering device capabilities, ensuring accurate and reliable information is available for compatible profile selection without human error.
Solution Approach 2:
The system implements a feedback mechanism where the subscriber entity's capability information is directly fed back to the SM-DP+ server during the profile download process. This feedback loop enables the server to automatically select compatible profiles based on actual device capabilities, replacing error-prone manual allocation with automated decision-making.
2Adaptability or versatility
If MNO requests subscriber device information for profile allocation, then profile type can be determined, but the process becomes error-prone and time-consuming
Solution Approach 1:
The subscriber entity prepares and provides capability information proactively during the profile download initiation phase, before the SM-DP+ server needs to select a profile. This preliminary action ensures that all necessary information is available upfront, enabling immediate automated profile selection without time-consuming manual information gathering by the MNO.
3Productivity
If generic profiles are ordered without eUICC capability information, then batch subscriptions can be processed, but compatibility issues arise with specific devices
Solution Approach 1:
Instead of using a single generic profile for all devices in a batch, the system applies local quality by customizing profile selection based on each subscriber entity's specific capability information. The SM-DP+ server selects profiles tailored to individual device characteristics within the batch, ensuring compatibility while maintaining efficient automated processing.
Solution Approach 2:
The system changes the key parameter of capability information from unknown (in generic batch processing) to known and specific (through subscriber-provided information). This parameter change enables the SM-DP+ server to differentiate between devices in a batch and select appropriate profiles, maintaining productivity while improving compatibility.
