eSIM Entitlement Service Discovery Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current eSIM entitlement solutions lack a standardized service discovery mechanism, leading to high complexity and costs for smaller operators and OEMs, as they must align with each network's unique setup, limiting the deployment of eSIM devices across different networks.
Innovation Solution
Implementing a service discovery method that involves a device connecting to an entitlement configuration server to validate and agree on parameters and methodologies for eSIM activation, using standardized methods from TS.43, enabling interoperability by defining a specific set of implementation possibilities such as profile-delivery, polling/pushing behavior, and protocol support through interfaces like REST or SOAP.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each operator aligns with every OEM on a custom implementation for their specific network, then the eSIM entitlement can be activated for that specific network-OEM pair, but the complexity and cost increase significantly
Solution Approach 1:
The patent implements a universal entitlement configuration server that can serve multiple operators and OEMs with a single standardized interface. The server is designed to handle diverse eSIM entitlement scenarios (primary device, secondary device, subscription transfer) through a common architecture, eliminating the need for custom implementations for each operator-OEM pair while maintaining full functionality.
Solution Approach 2:
The patent segments the entitlement infrastructure into standardized modular components: a universal entitlement configuration server, standardized API interfaces, and modular entitlement verification processes. This segmentation allows different operators and OEMs to interact with the same system through consistent interfaces without requiring end-to-end custom integration.
2Device complexity
If a standardized entitlement infrastructure is implemented, then the complexity and cost are reduced for smaller operators and OEMs, but the system must support multiple possible setup configurations
Solution Approach 1:
The patent implements a dynamic entitlement configuration server that can adapt its behavior based on the specific operator and device capabilities. The server dynamically determines the appropriate entitlement methodology (TS.43 for primary devices, alternative methods for secondary devices) based on real-time device information, providing both standardization and flexibility simultaneously.
Solution Approach 2:
The patent uses parameter-based configuration where the entitlement server accepts various input parameters (device type, operator network type, subscription status) and automatically adjusts its operation mode accordingly. This allows a single standardized system to support multiple setup configurations without requiring manual customization for each case.
3Adaptability or versatility
If multiple entitlement methodologies are supported, then more device types and network configurations can be accommodated, but the validation and comparison process becomes more complex
Solution Approach 1:
The patent introduces an intermediary entitlement configuration server that acts as a mediator between diverse devices and operators. The server handles the complexity of validating multiple entitlement methodologies (TS.43, alternative activation methods) centrally, while devices and operators interact through simplified standardized interfaces. The intermediary absorbs the validation complexity rather than distributing it across all system components.

AI summary
A service discovery method for activating an embedded subscriber identity module (eSIM) device includes: initiating a device comprising an eSIM; and connecting the device to at least one of an entry point of a mobile network operator and a designated entitlement configuration server, using an entitlement configuration for automatically activating the eSIM via the connection to the entitlement configuration server and connecting the eSIM with a data service or a data network of the mobile network operator based on an entitlement of designated use-cases. The device and the entitlement configuration server validate parameters and/or methodologies for the entitlement configuration. The device requests the entitlement configuration server to provide supported parameters for a designated use-case and compares the response returned by the entitlement configuration server with its own supported parameters for the designated use-case.
