SMS Ring Volume Adjustment via Missed Call Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often miss urgent calls due to their mobile phones being set to silent or vibration mode, and failing to revert to ring mode after events, resulting in missed notifications.
Innovation Solution
A method using short message service (SMS) to adjust the ring volume of a communication device to the maximum level when specific conditions are met, such as multiple missed calls, non-maximum volume setting, and recent call frequency, allowing for automatic or user-initiated volume adjustment through defined information element identifiers (IEIs) in transfer protocol user data (TPUD).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the mobile phone is set to silent mode or vibration mode for different conditions, then the user can avoid noise disturbance, but the user may miss urgent calls
Solution Approach 1:
The system implements feedback by monitoring missed call information and automatically triggering a volume adjustment mechanism. When the communication device receives missed call data, it analyzes the information and sends control instructions back to adjust the ring volume, creating a closed-loop feedback system that responds to notification failures.
Solution Approach 2:
The communication device performs self-service by automatically detecting missed calls and adjusting its own ring volume without requiring external intervention. The device monitors its own notification status and autonomously modifies its volume settings to prevent future missed calls.
2Ease of operation
If the user forgets to set the mobile phone back to ring mode after an event, then the phone remains in silent or vibration mode, but urgent calls are missed
Solution Approach 1:
The system eliminates the need for manual intervention by implementing self-service functionality. The communication device automatically monitors for missed calls and adjusts the ring volume accordingly, removing the burden of manual mode switching from the user while ensuring reliable call notification.
Solution Approach 2:
The system takes preliminary action by proactively adjusting the ring volume based on missed call detection before another urgent call can be missed. The automatic volume adjustment occurs as a preventive measure, ensuring the device is ready to notify the user of subsequent important calls.
3Object-affected harmful factors
If the ring volume is too small, then the user can avoid noise disturbance, but the user will miss urgent calls
Solution Approach 1:
The ring volume transitions from a static setting to a dynamic parameter that automatically adjusts based on missed call conditions. The system enables the volume to change adaptively, increasing when missed calls are detected and maintaining lower levels during normal operation, thus resolving the contradiction between noise avoidance and call notification reliability.

AI summary
A method for adjusting ring volume through short message service includes steps of a communication device determining whether a volume adjusting condition is satisfied when there is a missed call; the communication device transmitting a first short message if the volume adjusting condition has been satisfied, wherein a first information element identifier (IEI) is set in the first short message and defined as a volume adjusting request in transfer protocol user data (TPUD) in advance; the communication device determining whether a second IEI is set in a second short message when receiving the second short message, wherein the second IEI is defined as a volume adjusting response in TPUD in advance; and the communication device selectively adjusting a ring volume thereof to maximum level if the second IEI is set in the second short message.
