Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices cannot obtain and transfer activity information of applications when their battery levels are low, disrupting user experiences.
Innovation Solution
A method and device that detect low battery levels, select a nearby terminal device with sufficient battery power using the same user account, and transfer activity information to ensure continuity of application data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device operates normally to maintain application activity information, then the user experience is maintained, but the device consumes battery power and eventually runs out of power
Solution Approach 1:
The system proactively transfers application activity information from the first terminal device to the second terminal device before the first device completely runs out of power. This preliminary action ensures that user data and application states are preserved on a powered device, maintaining service availability without requiring the low-power device to continue operating.
Solution Approach 2:
The system introduces a server as an intermediary to facilitate the transfer of application activity information between terminal devices. The server receives the information list from the first terminal device and pushes it to the second terminal device, enabling seamless data transfer without requiring direct peer-to-peer communication between devices.
2Loss of energy
If the terminal device stops operation to conserve battery power, then energy consumption is reduced, but application activity information becomes inaccessible
Solution Approach 1:
The system creates a copy of the application activity information from the first terminal device and transfers it to the second terminal device. This copying mechanism allows the original device to power down and conserve battery while the copied information remains accessible on the second device, eliminating the trade-off between energy conservation and information accessibility.
3Reliability
If the system transfers data between devices to maintain accessibility, then information availability is improved, but system complexity increases
Solution Approach 1:
The server provides universal functionality by handling multiple tasks: receiving information lists from various terminal devices, managing user account associations, and pushing data to appropriate target devices. This multi-functional approach consolidates complexity in a centralized system rather than requiring complex peer-to-peer communication logic in each device.

AI summary
Embodiments of this application relate to the field of communications technologies, and provide an information processing method and a device, to resolve a problem that activity information of an application on a terminal device cannot be obtained when the terminal device runs out of power. The method includes: A first terminal device obtains activity information of an application on the first terminal device when a battery level of the first terminal device is less than or equal to a first threshold. The first terminal device determines a second terminal device, where the second terminal device is a terminal device selected from an available device, the available device is an online device that uses a same user account as the first terminal device, and a battery level of the available device is greater than or equal to a second threshold. The first terminal device pushes the activity information of the application on the first terminal device to the second terminal device.
