Mobile Device Notification Service Connection Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face challenges in efficiently managing notification service connections to conserve battery life and maintain network connectivity while in sleep mode, as they typically cannot refresh data contexts and may experience connection timeouts if not actively used.
Innovation Solution
A mobile device schedules notification service connection message transmission intervals and wakes up only when necessary to transmit these messages, ensuring that both push and pull notification services remain connected without constant active usage, thereby conserving battery life and maintaining network connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the mobile device enters sleep mode to conserve battery life, then energy consumption is reduced, but the device cannot refresh data contexts and may experience connection timeouts
Solution Approach 1:
The device performs preliminary actions by scheduling and transmitting notification service connection messages during brief wake intervals before returning to sleep mode. This allows the device to proactively maintain connection freshness without needing to stay continuously awake, resolving the contradiction between energy conservation and connection reliability.
Solution Approach 2:
The device implements periodic wake-sleep cycles with scheduled transmission intervals. Instead of continuous operation, the device periodically wakes to transmit connection messages and then returns to sleep mode. This periodic action pattern maintains notification service connections while minimizing overall energy consumption compared to continuous active operation.
2Reliability
If the device wakes up frequently to refresh connections, then network connectivity is maintained, but battery life is reduced
Solution Approach 1:
The device uses periodic wake-sleep cycles with optimized transmission intervals. By scheduling connections at specific periodic intervals rather than continuously, the device maintains network connectivity while minimizing the frequency and duration of wake events, thus reducing overall energy consumption.
Solution Approach 2:
The device maintains continuous notification service connection through scheduled transmissions during brief wake intervals. The connection state is preserved across sleep-wake cycles, ensuring continuous useful action (maintained connectivity) without requiring continuous device wakefulness, thereby reducing energy consumption.
3Reliability
If the device stays awake to maintain active connections, then notification services remain connected, but energy consumption increases
Solution Approach 1:
The device performs connection maintenance as a preliminary action during scheduled wake intervals. By proactively transmitting connection messages before the connection would timeout, the device maintains notification service reliability without needing to stay continuously awake, thus reducing energy loss.
Solution Approach 2:
The device implements periodic connection refreshes instead of continuous active connections. By waking at scheduled intervals to transmit connection messages and then returning to sleep mode, the device maintains notification service connections while minimizing energy consumption compared to continuous wakeful operation.

AI summary
A method and apparatus to manage notification service connections. In one embodiment of the invention, a mobile device schedules a notification service connection message transmission interval for each of a plurality of notification service connections. The mobile device also associates a notification service connection message transmission window with each notification service connection message transmission interval. The mobile device synchronizes transmission of notification service connection messages based on overlapping notification service connection message transmission windows.
