Throttling Persistent Always ON Apps for Wireless Handoff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Persistent always ON applications in wireless devices fail to switch to alternative wireless networks when the home network signal is interrupted, leading to missed opportunities for stronger connections due to continuous attempts to re-establish the home network link.
Innovation Solution
Implementing a method to throttle the persistent always ON application by comparing the home signal parameters to a threshold, allowing the device to switch to alternative wireless networks using a single RF chain and compatible access technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continuously attempts to reconnect to the home wireless network, then the persistent always ON application maintains its data session, but the UE cannot connect to alternative wireless networks when the home network link is interrupted
Solution Approach 1:
The system dynamically adjusts the behavior of persistent always ON applications based on signal conditions. When the home network signal falls below a threshold, the system temporarily suspends reconnection attempts and enables alternative network connectivity. This dynamic adaptation allows the UE to switch between home and alternative networks based on real-time signal quality, resolving the contradiction between maintaining data session continuity and enabling alternative network access.
Solution Approach 2:
The system changes the operational parameters of the persistent always ON application by introducing a signal threshold parameter. When the home network signal parameter (signal strength) falls below the threshold, the system modifies the application's behavior to allow alternative network connections. This parameter-based control enables the system to balance data session continuity with alternative network availability based on signal conditions.
2Device complexity
If the UE uses a single RF chain for persistent always ON applications, then the device complexity is reduced, but the UE cannot simultaneously monitor and switch to alternative wireless networks
Solution Approach 1:
The system performs preliminary actions by pre-configuring alternative networks and preparing handoff procedures before actual switching is needed. The UE maintains a list of alternative wireless networks and pre-establishes the necessary parameters for potential handoffs. When the home network signal deteriorates, the system can quickly execute pre-prepared handoff procedures using the single RF chain, enabling alternative network connectivity without requiring multiple RF chains for simultaneous monitoring.
3Adaptability or versatility
If the UE throttles the persistent always ON application, then the UE can connect to alternative wireless networks, but the data session may be interrupted
Solution Approach 1:
The system implements feedback mechanisms that continuously monitor signal conditions and adjust application throttling accordingly. When the home network signal recovers above the threshold, the system receives feedback and automatically resumes normal operation of persistent always ON applications. This feedback-based control ensures that throttling is applied only when necessary and that data session continuity is restored as soon as conditions permit, balancing alternative network switching with session reliability.
