eUICC Connectivity Management via Proxy Node Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current standards do not provide guidance on how to connect a specific embedded Universal Integrated Circuit Card (eUICC) with a unique eUICC-ID to more than one Subscription Manager-Data Preparation (SM-DP) and Subscription Manager-Secure Router (SM-SR) entity, limiting flexibility in network connectivity management.
Innovation Solution
A method and node configuration that acquire and store associations between the eUICC-ID, SM-DP entity identities, and SM-SR entity identities, allowing dynamic changes to these associations, enabling flexible management of network connectivity by creating a table that maps SM-DP-ID, SM-SR-ID, and eUICC-ID triplets, facilitating connections to multiple SM-DP and SM-SR entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current standards are followed for eUICC connectivity management, then the system maintains standard compliance and simplicity, but the system lacks flexibility to connect eUICC to multiple SM-DP and SM-SR entities
Solution Approach 1:
The patent segments the connectivity management by introducing a proxy node that separates the eUICC from direct connections to multiple SM-DP and SM-SR entities. The proxy node acts as an intermediary that manages multiple connections independently, allowing the eUICC to maintain a simple interface while the proxy handles the complexity of multiple entity connections.
Solution Approach 2:
The patent introduces a proxy node as an intermediary between the eUICC and multiple SM-DP/SM-SR entities. This intermediary enables the eUICC to connect to multiple entities indirectly through the proxy, which manages the associations and routing. The proxy node mediates all communications, allowing flexible connectivity without requiring the eUICC to directly manage multiple complex connections.
2Adaptability or versatility
If eUICC is connected to multiple SM-DP and SM-SR entities, then the system supports multiple subscription profiles and enhances connectivity flexibility, but the system complexity and management overhead increase
Solution Approach 1:
The proxy node implements self-service mechanisms by automatically managing the associations between eUICC-ID, SM-DP-ID, and SM-SR-ID. The system can dynamically create, update, and remove associations without manual intervention. The proxy node autonomously handles the complexity of managing multiple subscription profiles and entity connections, reducing the management overhead for operators and system administrators.
3Adaptability or versatility
If dynamic changes to associations are enabled, then the system allows flexible reconfiguration of connectivity, but the system requires more complex update and management mechanisms
Solution Approach 1:
The patent implements dynamic association management where the proxy node can create, update, and remove associations between eUICC-ID, SM-DP-ID, and SM-SR-ID in real-time. The system supports dynamic reconfiguration of connectivity without requiring physical eUICC replacement or system reboots. Associations can be modified through OTA commands, allowing flexible adaptation to changing network conditions and subscription requirements.

AI summary
The invention relates to a node for managing network connectivity of a device comprising an embedded Universal Integrated Circuit Card (eUICC). The node is configured to provision the eUICC for network connectivity of the device. The method comprises acquiring an identity of at least one Subscription Manager-Data Preparation (SM-DP) entity, acquiring an identity of at least one Subscription Manager-Secure Router (SM-SR) entity, creating an association between the identity of the at least one SM-DP entity, the identity of the at least one SM-SR entity and an identity of the eUICC, and storing the created association, wherein the stored association subsequently can be changed for the eUICC by changing at least one of the identity of the at least one SM-DP entity and the identity of the at least one SM-SR entity with which the eUICC is to be associated.
