Adaptive Call Notification Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile telephone manufacturers aim to reduce power consumption to extend battery life, as vibration devices consume power and may not always be necessary or desirable for incoming call notifications.
Innovation Solution
An adaptive call notification method and system that counts incoming ring signals and activates the vibration device only when the ambient sound level exceeds a threshold and a predetermined number of ring signals are received, with optional user-selectable settings for vibration intensity and battery life considerations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vibration device is activated for every incoming call notification, then the user is ensured to notice the call, but the power consumption increases reducing battery life
Solution Approach 1:
The system changes the operational parameters of the vibration device based on ambient sound level measurements. When the ambient sound exceeds a threshold, the vibration device is activated with specific pulse widths and voltage levels. This parameter-based control ensures reliable notification in noisy environments while avoiding unnecessary activation in quiet environments, thus resolving the contradiction between notification effectiveness and power consumption.
2Reliability
If the vibration device is activated frequently to ensure call notification, then the user reliability is improved, but the battery life is reduced due to increased power consumption
Solution Approach 1:
The system continuously monitors the ambient sound level and uses this feedback to determine whether to activate the vibration device. The controller compares the measured ambient sound against a threshold and adjusts vibration activation accordingly. This feedback mechanism ensures the vibration device operates only when necessary, maintaining notification reliability while extending battery life by avoiding unnecessary activations.
3Use of energy by moving object
If the vibration device is deactivated to save power, then power consumption is reduced extending battery life, but the user may miss incoming calls in noisy environments
Solution Approach 1:
The system dynamically adjusts the activation state of the vibration device based on real-time ambient sound conditions. Rather than a static on/off state, the system transitions between states based on the measured sound level. When ambient noise exceeds the threshold, the vibration device becomes active with appropriate pulse characteristics. This dynamic adaptation ensures power savings in quiet environments while maintaining notification effectiveness in noisy environments.

AI summary
A method for adaptive call notification in a user equipment (UE) includes detecting an incoming call indication such as a ring signal. The ambient sound level for the UE is measured in response to the incoming call indication. A UE vibration device is activated in response to the detected incoming call indication and the ambient sound level being greater than a user-selectable threshold.
