eSIM Profile Management Platform ICCID Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing eSIM profile management systems face challenges in efficiently distributing eSIM profiles to eUICCs due to issues like premature requests, misrouting of profiles between subscription management services, and lack of real-time access control, leading to errors and unauthorized access.
Innovation Solution
The eSIM profile management platform receives service data feeds from multiple subscription management services, which include ICCIDs and associated identification information, enabling it to regulate access, detect errors, and ensure correct routing of eSIM profiles, thereby preventing unauthorized access and ensuring accurate profile deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the eSIM profile management platform receives requests to distribute eSIM profiles before they arrive at the profile data store, then the system can respond to distribution requests, but the subscription management service fails to distribute the eSIM profile and the cause of the error is not immediately apparent
Solution Approach 1:
The system performs preliminary actions by pre-validating profile availability status in the profile data store before processing distribution requests. This allows the system to respond to requests while preventing failures by ensuring profiles are ready for distribution.
Solution Approach 2:
The system implements feedback mechanisms where the profile data store provides real-time status information about profile availability to the eSIM profile management platform. This feedback loop enables the platform to make informed decisions about request handling and provides visibility into distribution status.
2Adaptability or versatility
If multiple subscription management services interface with the eSIM profile management platform, then the system can serve multiple services, but incoming ordered eSIM profiles may be accidentally routed to the wrong subscription management service's profile data store
Solution Approach 1:
The system segments the profile data store into service-specific partitions or logical sections, where each subscription management service has its own designated storage area. This segmentation prevents profiles from one service from being accidentally routed to another service's data store.
Solution Approach 2:
The eSIM profile management platform acts as an intermediary between the profile data store and subscription management services. It includes validation logic that verifies the correct service is accessing the correct profile data, preventing misrouting while maintaining multi-service support.
3Device complexity
If the system lacks real-time access control for eSIM profiles, then the system can operate simpler, but unauthorized access to profiles may occur
Solution Approach 1:
The system performs preliminary access control checks by validating user authorization status before allowing profile access. This pre-validation approach provides real-time protection against unauthorized access while maintaining manageable system complexity through automated enforcement.
Solution Approach 2:
The system implements real-time feedback mechanisms where the access control module continuously monitors user authorization status and provides feedback to the profile management operations. This enables dynamic access control decisions based on current user status without requiring complex manual intervention.
Data Source
AI summary
One or more service data feeds that indicate a plurality of consumer eSIM profiles received are loaded into one or more profile data stores of at least one subscription management service are received at an Embedded Subscriber Identity Module (eSIM) profile management platform of a wireless communication carrier. A request from an entity to perform an action with respect to a particular consumer eSIM profile having a specific Integrated Circuit Card identifier (ICCID) may be received at the eSIM profile management platform. A request for performing the action with respect to the particular consumer eSIM profile is forwarded by the eSIM profile management platform to a subscription management service at least in response to determining that the specific ICCID matches an ICCID of a consumer eSIM profile that is indicated by the service data feed as being loaded into the profile data store of the subscription management service.
