Virtual SIM User Data Transfer Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User data cannot be conveniently transferred together with SIM card data when a virtual SIM card is transferred between terminals, requiring separate handling which is inconvenient for users.
Innovation Solution
A method and terminal device configuration that allows user data associated with a virtual SIM card to be acquired and sent to a server or directly to another terminal, using storage addresses included in the SIM card data, enabling seamless transfer of user data such as contact information, messages, images, and audio data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a virtual SIM card is transferred between terminals, then the SIM card data can be transferred, but the user data cannot be transferred together with the SIM card data
Solution Approach 1:
The patent merges the transfer of user data with the transfer of virtual SIM card data into a single integrated process. When a virtual SIM card is transferred from one terminal to another, the system automatically includes and transfers associated user data (contact information, messages, images, audio data) as part of the same transfer operation, eliminating the need for separate data transfer steps and improving user convenience.
Solution Approach 2:
The patent introduces a server as an intermediary to facilitate the transfer of user data during virtual SIM card migration. The server acts as a mediator that receives user data from the source terminal, stores it temporarily, and then transfers it to the destination terminal, enabling seamless data transfer even when direct terminal-to-terminal transfer is not feasible.
2Productivity
If user data is transferred separately from SIM card data, then the SIM card data transfer is simple, but the user processing steps increase
Solution Approach 1:
The patent combines the transfer operations for virtual SIM card data and user data into a single unified process. Instead of requiring users to perform separate transfer operations for SIM data and user data, the system integrates both transfers into one operation, significantly reducing the time and steps required for data migration while improving overall transfer efficiency.
3Adaptability or versatility
If a physical SIM card is used, then user data can be stored in the SIM card storage space, but the terminal cannot provide multiple virtual SIM cards
Solution Approach 1:
The patent enables terminals to support multiple virtual SIM cards simultaneously, each capable of storing and managing its own associated user data. This multi-functional capability allows a single terminal to host multiple independent virtual SIM card instances, providing versatility similar to physical SIM cards while maintaining the convenience of digital management and user data association.

AI summary
Embodiments of the present invention provide methods for sending and receiving user data and terminal devices, to resolve a problem that user data cannot be transferred together with SIM card data. The method includes: receiving, by a first terminal, an instruction for transferring a virtual subscriber identity module SIM card of the first terminal, to a second terminal; acquiring, by the first terminal according to the instruction, user data associated with the virtual SIM card; and sending, by the first terminal, the user data to a server, or sending, by the first terminal, the user data to the second terminal.
