Battery Level Prompting for Failed Mobile Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication terminals often shut down due to low battery levels, leading to failed calls and unnecessary worries for users, as existing solutions do not effectively notify callers of the battery state before attempting to connect.
Innovation Solution
A method and apparatus that utilize a server to store and retrieve battery level information for called telephone numbers, sending a notification to the calling user if the battery level is below a preset value, preventing repeated attempts and informing the user of the shut down due to low battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the calling terminal attempts to connect when battery level information is not checked, then the calling process can proceed normally, but the calling user experiences unnecessary worries and repeated call attempts due to unknown battery state
Solution Approach 1:
The system performs preliminary action by obtaining and checking battery level information from the battery level information bank before the calling terminal attempts to establish a connection. This advance check prevents the calling user from experiencing unnecessary worries and repeated call attempts, as the battery state is known beforehand.
Solution Approach 2:
The system implements feedback by providing battery level information to the calling terminal through the server. This feedback mechanism enables the calling user to know the battery state of the called terminal, preventing unnecessary repeated call attempts and reducing user anxiety.
2Reliability
If the system obtains battery level information from the battery level information bank before calling, then the calling user is informed of the battery state, but additional system operations and data retrieval steps are required
Solution Approach 1:
The server acts as an intermediary between the battery level information bank and the calling terminal. The server receives the called telephone number, queries the battery level information bank, and returns the battery level information to the calling terminal. This intermediary approach simplifies the overall system architecture while maintaining reliability.
3Adaptability or versatility
If the server stores and manages battery level information for multiple telephone numbers, then comprehensive battery state monitoring is achieved, but server storage and processing requirements increase
Solution Approach 1:
The system extracts only the necessary battery level information from the battery level information bank based on the called telephone number. Rather than storing or processing all possible battery information, the system selectively retrieves only the relevant data needed for the current calling scenario, reducing storage and processing requirements.

AI summary
The present invention relates to a prompting method and apparatus. The method includes: receiving (S11) a calling telephone number and a called telephone number sent by a calling terminal when calling of the called telephone number is failed; obtaining (S12) stored battery level information associated with the called telephone number from a battery level information bank, battery level information uploaded by a terminal corresponding to a telephone number if a battery level is lower than a first preset value being stored in the battery level information bank; and if the obtained battery level information indicates a preset low battery level state, sending (S13) a notification message indicating that a terminal corresponding to the called telephone number has been shut down due to a low battery level to the calling telephone number.
