Cognitive Assistant Reroutes Mobile Communications in Low Power Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices in low power mode may miss important communications, such as urgent emails or instant messages, and fail to receive critical app updates, posing a risk of missed notifications and security vulnerabilities due to limited background processing.
Innovation Solution
A cognitive assistant system that reroutes communications from servers to a cloud-based hardware processor, analyzes their content using natural language processing, assigns weights based on urgency, and transmits only high-priority communications to the mobile device, while temporarily disabling non-critical apps until the device exits low power mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the device limits background processing and turns off features to save battery life, then battery consumption is reduced, but important communications may be missed and security risks increase
Solution Approach 1:
The patent segments incoming communications into different priority levels (urgent vs. non-urgent) and applies different handling strategies to each segment. High-priority communications are routed through alternative paths that ensure delivery even in low power mode, while low-priority communications are deferred or suppressed, resolving the contradiction by selectively maintaining reliability for critical functions while allowing battery savings for non-critical ones
Solution Approach 2:
The patent introduces an intermediary mechanism (such as a server or cloud-based service) that acts as a mediator between the sender and the mobile device. This intermediary holds and manages communications, allowing the device to enter low power mode while the intermediary ensures that urgent communications are still delivered when the device becomes active, thus maintaining communication reliability without requiring continuous device availability
2Loss of energy
If the device restricts background processing in low power mode, then energy consumption decreases, but critical app updates and security patches cannot be applied
Solution Approach 1:
The patent applies preliminary action by pre-identifying and prioritizing critical updates and security patches before the device enters low power mode. These high-priority updates are marked for deferred installation, allowing the device to save energy during normal operation while ensuring that security-critical updates are automatically applied when the device exits low power mode or during scheduled maintenance windows
Solution Approach 2:
The patent changes the operational parameters of background processing based on power mode. In low power mode, the system dynamically adjusts which processes are allowed to run, permitting only critical security and update-related processes while restricting non-essential background activities. This parameter adjustment allows energy savings while maintaining security update capability
3Duration of action of moving object
If the device disables background email fetch and messaging features, then battery life is extended, but urgent communications requiring immediate attention are missed
Solution Approach 1:
The patent applies local quality by enabling different operational modes for different communication channels or message types. Instead of uniformly disabling all background processing, the system selectively maintains background fetch capabilities for high-priority communication channels (such as urgent email accounts or critical messaging services) while disabling them for lower-priority channels, thus preserving battery life overall while ensuring urgent communications are not missed
Data Source
AI summary
A cognitive assistant for mobile devices in low power mode. A first signal may be received from a mobile device via a communication network, the first signal indicating that the mobile device entered low power mode. Responsive to receiving the first signal, communications from a plurality of servers directed to the mobile device may be rerouted to another hardware processor, wherein the hardware processor receives the communications instead of the mobile device receiving the communications. The hardware processor may analyze the communications' content and assign weights to the communications. A selected set of communications that are assigned weights exceeding a threshold value is transmitted to the mobile device in low power mode.
