Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for activating multiple IMSI single MSISDN services are cumbersome and costly, requiring users to visit customer service centers and undergo lengthy procedures, which negatively impacts user experience and operator costs.
Innovation Solution
A profile download method that allows a primary device with a UICC to obtain and send profile download information to a secondary device with an eUICC, enabling the secondary device to download and install a profile from a profile management server, thereby simplifying the activation of multiple IMSI single MSISDN services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users visit customer service centers to activate multiple IMSI single MSISDN services, then service activation can be completed, but user time and energy are consumed and customer experience deteriorates
Solution Approach 1:
The patent enables users to activate multiple IMSI single MSISDN services through self-service mechanisms. The system automatically retrieves user information, generates profile download links, and completes service activation without requiring physical presence at customer service centers. Users can complete the entire process remotely through their devices, eliminating the need for manual intervention by service personnel.
Solution Approach 2:
The patent introduces an automated system as an intermediary between the user and the service activation process. This system acts as a digital mediator that handles information retrieval, profile generation, and service activation automatically. The intermediary system processes user requests through automated workflows, replacing the need for human-to-human interaction at physical service centers.
2Ease of manufacture
If customers scan quick response codes at customer service centers to download profiles, then profile download can be achieved, but operator financial costs and staff training costs increase
Solution Approach 1:
The patent enables automated profile download through self-service mechanisms. The system automatically generates profile download links or quick response codes that users can scan with their devices. This eliminates the need for customer service center staff to manually assist with profile downloads, reducing both financial costs and training requirements while maintaining ease of profile acquisition.
Solution Approach 2:
The patent extracts the profile download function from the physical customer service center environment and relocates it to a digital automated system. By separating this function from human staff and physical locations, the system eliminates the need for staff training and reduces operational costs while preserving the ability for users to download profiles conveniently.
3Adaptability or versatility
If multiple IMSI single MSISDN service is activated through traditional methods, then service activation is achieved, but customer service center infrastructure and staff training requirements increase
Solution Approach 1:
The patent introduces an automated digital intermediary system that handles multiple IMSI single MSISDN service activation. This intermediary processes service requests, manages profile generation, and coordinates activation automatically. By replacing physical customer service center infrastructure with a digital automated system, the patent reduces infrastructure complexity while maintaining service versatility.
Solution Approach 2:
The patent creates a universal automated system that can handle multiple IMSI single MSISDN service activations through a single standardized process. This multi-functional system replaces the need for specialized customer service center infrastructure and trained staff, as the automated system performs all necessary functions through standardized digital workflows applicable to all users.

AI summary
A profile download method includes a primary device obtaining an embedded integrated circuit card identifier (EID) of a secondary device, where the EID is used by the primary device to obtain, from a mobile operator server, profile download information that matches the EID. The primary device receives the profile download information from the mobile operator server and sends the profile download information to the secondary device, where the profile download information is used by the secondary device to download a profile from a profile management server, and where the profile is installed in an embedded UICC (eUICC) of the secondary device after the download is complete.
