Single-QR eSIM Provisioning Across Multiple DP+ Servers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eSIM provisioning systems in wireless communication networks are inefficient as they typically use a single static QR code to connect to a single DP+ server, limiting the ability of mobile network operators to optimally distribute eSIM profiles across multiple servers based on demand and use cases.
Innovation Solution
Implementing a system where a single QR code contains the address of a primary DP+ server that is communicatively coupled to multiple secondary DP+ servers, allowing the Local Profile Assistant to access these servers to identify and download the appropriate eSIM profile for a user device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single static QR code is used to connect to a single DP+ server, then the user experience remains simple and seamless, but the system cannot optimally distribute eSIM profiles across multiple servers based on demand and use cases
Solution Approach 1:
The patent introduces a primary DP+ server as an intermediary that receives QR code information from user devices and coordinates with multiple secondary DP+ servers. This mediator architecture enables the system to access multiple profile repositories without requiring changes to the user-facing QR code mechanism, thus resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The patent segments the profile management system into a primary DP+ server that handles coordination and multiple secondary DP+ servers that store specific profile inventories. This segmentation allows the system to distribute eSIM profiles across multiple servers while maintaining a unified access point through the single QR code, balancing versatility with operational simplicity.
2Productivity
If multiple DP+ servers are introduced to optimize eSIM profile distribution, then profile availability and customization improve, but the complexity of the provisioning system increases
Solution Approach 1:
The patent merges multiple secondary DP+ servers into a coordinated network managed by a primary DP+ server. This combining approach allows the system to leverage multiple profile inventories for improved productivity and profile availability while presenting a unified, simple interface to user devices through the existing QR code mechanism.
Solution Approach 2:
The primary DP+ server is designed with multi-functionality, serving as both an access point for QR code information and a coordinator for multiple secondary servers. This universal component enables improved profile distribution efficiency without requiring separate complex systems for each function, thus managing complexity while enhancing productivity.
3Adaptability or versatility
If the Local Profile Assistant is upgraded to access multiple servers directly, then profile selection flexibility improves, but compatibility with existing devices and QR codes may be compromised
Solution Approach 1:
The patent implements preliminary action by having the primary DP+ server pre-coordinate with multiple secondary servers before user devices need to access profiles. This advance preparation enables flexible profile selection without requiring modifications to existing Local Profile Assistants or user devices, maintaining ease of manufacture and deployment while improving adaptability.
Solution Approach 2:
The primary DP+ server acts as an intermediary that shields user devices from the complexity of multiple servers. This mediator enables profile selection flexibility at the server level while maintaining simple, compatible interfaces for existing devices and QR codes, thus resolving the contradiction between adaptability and ease of manufacture.
Data Source
AI summary
The disclosed technology is directed to providing an embedded subscriber identity module (eSIM) solution in a wireless telecommunication network. An example method for provisioning a wireless device with an eSIM profile for operation on a network includes a primary DP+ server receiving a first information corresponding to a mobile device. The primary DP+ server, which is communicatively coupled to a plurality of secondary DP+ servers, is accessed via network information embedded in a single quick response (QR) code that was retrieved by scanning the single QR code. The method further includes determining whether an appropriate eSIM profile is available on the primary DP+ server or one of the secondary DP+ servers. In the former case, the identified eSIM is transmitted to the mobile device, whereas in the latter case, the identified eSIM profile is received from the respective secondary DP+ server and then transmitted to the mobile device.
