Mobile Data Migration via QR Code Compatibility Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When users switch mobile phones, some applications from the old phone may not be available on the new phone due to compatibility issues, leading to data loss and inconvenience.
Innovation Solution
A method for data migration that involves scanning a two-dimensional code to obtain attribute information of the new terminal, determining compatible applications, performing data backup on those applications, and transmitting the backed-up data to the new terminal, ensuring that only compatible applications are migrated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If all data is migrated from the old terminal to the new terminal, then data completeness is improved, but data reliability deteriorates due to compatibility issues
Solution Approach 1:
The patent changes the parameter of data selection from 'all data' to 'compatible data' by introducing compatibility judgment based on terminal attributes. The system scans the two-dimensional code of the new terminal to obtain its attributes, then determines which applications are compatible before migrating only those applications and their associated data, thus ensuring both completeness and reliability.
Solution Approach 2:
The patent performs preliminary compatibility assessment before data migration by scanning the new terminal's attributes and determining compatible applications in advance. This preliminary action prevents incompatible data from being migrated, ensuring that only data that can be successfully restored on the new terminal is transferred.
2Reliability
If compatibility checking is performed before data migration, then data reliability is improved, but migration complexity increases
Solution Approach 1:
The patent introduces a two-dimensional code as an intermediary to carry terminal attribute information. Instead of directly comparing complex terminal configurations, the system uses the simplified two-dimensional code scanning process to obtain new terminal attributes, then matches these with old terminal attributes to determine compatibility. This intermediary approach simplifies the complexity of direct compatibility verification.

AI summary
A method for data migration is provided. The method includes the following. A first terminal obtains attribute information of a second terminal by scanning a two-dimensional code of the second terminal. The first terminal determines a first application compatible with the second terminal according to the attribute information of the second terminal. The first terminal obtains a first data set by performing data backup on the first application and transmits the first data set to the second terminal. Related devices are further provided. Embodiments of the present disclosure can avoid a problem that some applications in an old mobile phone are not available in a new mobile phone.
