Enterprise eSIM Onboarding for Scalable Profile Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing enterprise eSIM solutions lack scalability and are not well-defined, as they rely on a single global GSMA Root SM-DS that requires device EIDs, which are often unknown, leading to operational inefficiencies and high costs.
Innovation Solution
Implementing a separate MNO onboarding server that manages device registration and deregistration, allowing enterprises to allocate eSIM profiles flexibly without prior knowledge of device EIDs, using multiple OEM discovery servers and maintaining compliance with GSMA specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single global GSMA Root SM-DS is used for eSIM profile management, then compliance with GSMA specifications is maintained, but scalability and operational efficiency for enterprises deteriorate due to unknown device EIDs and high costs
Solution Approach 1:
The patent segments the single global GSMA Root SM-DS into multiple regional SM-DS instances (e.g., SM-DS US, SM-DS EU, SM-DS APAC) that are distributed across different geographic regions. Each regional SM-DS operates independently but complies with the same GSMA specifications, enabling scalable enterprise eSIM management while maintaining compliance. This segmentation allows enterprises to manage devices in specific regions without requiring knowledge of device EIDs, improving operational efficiency.
Solution Approach 2:
The patent introduces an intermediary component called the Discovery Server that acts as a mediator between enterprises and the SM-DS. The Discovery Server receives device information from enterprises, determines the appropriate regional SM-DS, and facilitates profile management without requiring enterprises to directly interact with the GSMA Root SM-DS. This intermediary layer improves operational efficiency by abstracting the complexity of EID management while maintaining GSMA compliance.
2Measurement precision
If device EIDs are required for eSIM profile allocation, then profile management precision is improved, but adaptability for enterprises with unknown device EIDs deteriorates
Solution Approach 1:
The patent implements preliminary action by having the Discovery Server proactively collect and register device information from enterprises before profile allocation is needed. The system pre-establishes a database of device EIDs and their corresponding enterprise accounts, allowing enterprises to allocate profiles without needing to provide EID information at the time of allocation. This preliminary registration maintains allocation accuracy while improving adaptability.
Solution Approach 2:
The system enables self-service by allowing enterprises to automatically manage their own eSIM profiles through the Discovery Server interface. Enterprises can register devices, allocate profiles, and manage subscriptions without manual intervention from the network operator. The system automatically matches devices with appropriate profiles based on pre-registered EID information, maintaining precision while providing flexible self-service capabilities.
3Device complexity
If a single global SM-DS is used, then system simplicity is maintained, but device complexity and operational costs increase due to lack of scalability
Solution Approach 1:
The patent segments the monolithic global SM-DS into multiple distributed regional instances, each handling a specific geographic region. This segmentation improves scalability by allowing regional expansion without requiring changes to the global system architecture. Each regional SM-DS maintains the same simple structure as the original single SM-DS, so system simplicity is preserved while scalability is achieved through the modular distributed architecture.

AI summary
Methods, apparatus, and systems for providing an embedded subscriber identity module (eSIM) solution are disclosed. In one example, a method for providing an eSIM solution to enterprises includes receiving, by a network server operated by a network operator, a request from an enterprise device management system requesting an eSIM profile for a communication device. The method also includes transmitting, by the network server, information to a discovery server associated with the communication device to register the communication device with the discovery sever.
