eSIM Profile Download via Machine-Readable Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current eSIM profile provisioning methods for user devices are inefficient, particularly for users who want to switch between different mobile network operators, as they often require manual steps and pre-printed machine-readable codes, leading to logistical issues and potential waste, and existing solutions like SM-DP+ are tied to specific MNOs, limiting flexibility.
Innovation Solution
The use of machine-readable codes, such as QR codes, to direct user devices to network portals or specific applications that facilitate the download of eSIM profiles by navigating to MNO network portals or SM-DP+ platforms, allowing users to select and activate subscription plans and download eSIM profiles seamlessly, with the option to specify promotion identifiers for limited-time offers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-printed machine-readable codes are used for eSIM profile provisioning, then users can obtain eSIM profiles, but logistical complexities and inventory waste increase
Solution Approach 1:
The patent replaces physical pre-printed machine-readable codes with a digital copy mechanism where the provisioning information is transmitted electronically through the network. The eSIM profile data is copied and transmitted over-the-air to the device, eliminating the need for physical code distribution and reducing inventory waste.
Solution Approach 2:
The patent substitutes the mechanical/physical distribution system (printing, shipping, and manual handling of pre-printed codes) with an electronic digital transmission system. Network messages and data packets replace physical codes, eliminating logistical complexities and inventory management requirements.
2Device complexity
If SM-DP+ platforms are tied to specific MNOs, then profile management is simplified, but flexibility for switching operators is reduced
Solution Approach 1:
The patent implements a universal eSIM profile provisioning system that can work with multiple mobile network operators through a single interface. The device can receive and process provisioning information from different operators using the same machine-readable code format and download mechanism, enabling multi-operator support without requiring separate systems for each operator.
3Reliability
If manual steps are required for eSIM profile activation, then security can be maintained, but user efficiency decreases
Solution Approach 1:
The patent incorporates security measures in advance within the provisioning information itself. The machine-readable code contains pre-configured security parameters, authentication data, and encrypted profile information that are validated automatically during the download process, eliminating the need for separate manual security verification steps while maintaining security integrity.
Data Source
AI summary
An activation request from a user device that includes a promotion identifier of a promotion campaign is received at a server, in which the promotion identifier is encapsulated by a machine-readable code that further includes a network address of the server. The activation request is routed from the user device to the server via the network address. A determination of whether an embedded Subscriber Identity Module (eSIM) profile associated with the promotion campaign is available for download to the user device is made. When the eSIM profile is available, the eSIM profile is sent to the user device such that the user device is able to use the eSIM profile to access telecommunication services of a Mobile Network Operator (MNO) according to one or more terms of the promotion campaign. When the eSIM profile is unavailable, an indication that the promotion identifier is invalid is sent to the user device.
