Adaptive Push Mail Filters for Battery Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current push mail applications drain battery power in wireless user equipment (UEs) due to frequent notifications, leading to battery depletion and disruption of device functionality, especially when the battery is low.
Innovation Solution
Implementing dynamic and event-driven push mail filters that adjust the frequency and amount of information sent to UEs based on their battery power levels, using protocols like P-IMAP and Sieve mail filtering language to conserve battery power by reducing notifications when the battery is low.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If push mail notifications are sent frequently to keep users informed of new emails, then information delivery timeliness is improved, but battery power consumption increases
Solution Approach 1:
The patent implements dynamic adaptation of push mail filter stringency based on monitored battery power levels. When battery level is high, the system uses less stringent filtering allowing more frequent notifications. When battery level drops below a threshold, the system automatically switches to more stringent filtering to reduce notifications and conserve power. This dynamic adjustment resolves the contradiction by making notification frequency adaptive rather than fixed.
Solution Approach 2:
The system changes the parameter of filter stringency (from less stringent to more stringent) based on battery power level conditions. This parameter change allows the system to optimize between information delivery and power consumption by adjusting filtering behavior according to available battery power, directly addressing the technical contradiction.
2Productivity
If the UE remains in a higher power consuming state to process email notifications, then email processing capability is improved, but battery drain increases
Solution Approach 1:
The system employs periodic monitoring of battery power levels and periodic adjustment of push mail filter settings. Rather than continuously processing emails at high power consumption, the system periodically checks battery status and periodically adjusts filtering stringency accordingly. This periodic action pattern allows the UE to operate in lower power states more frequently while still maintaining email processing capability when power is available.
3Loss of energy
If push mail filters are made more stringent to reduce notifications, then battery power consumption is reduced, but information delivery completeness deteriorates
Solution Approach 1:
The system implements feedback by continuously monitoring battery power levels and using this information to dynamically adjust filter stringency. The feedback loop ensures that when battery power is充足, the system maintains less stringent filtering to ensure complete information delivery. When battery power drops, the feedback triggers a switch to more stringent filtering to conserve power, thus resolving the contradiction through adaptive feedback control.

AI summary
One or more push mail filters of an email dispatcher is automatically, and preferably in an event-driven and dynamic manner, adapted to decrease the number of messages transmitted to a battery-operated user equipment (UE) based on one or more battery conservation parameters monitored by or for the UE.
