Personalized VoIP Handoff Thresholds via User Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handoff techniques in hybrid mobile devices between IP-based VoIP networks and cellular networks lack personalization, as they do not account for user feedback on connection quality, leading to suboptimal handoff decisions that affect user experience and network performance.
Innovation Solution
Incorporating user feedback into the handoff algorithm to establish a personalized handoff profile based on communication link parameters such as signal strength, jitter, latency, and packet loss, allowing for seamless transitions between networks based on user-defined quality thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manufacturer or carrier default settings are used for handoff determination, then device complexity is reduced and ease of operation is improved, but user experience and call quality are degraded due to lack of personalization
Solution Approach 1:
The system implements feedback mechanisms where user responses to call quality assessments are collected and used to adjust handoff thresholds. The device monitors call quality metrics and compares them against user feedback to dynamically refine handoff decision criteria, enabling personalized optimization without increasing operational complexity for the user.
Solution Approach 2:
The handoff threshold is transformed from a static default value to a dynamic parameter that adapts based on user feedback and observed call quality. The system continuously learns from user responses and adjusts thresholds in real-time, allowing the handoff decision mechanism to evolve and personalize to each user's preferences while maintaining ease of operation.
2Reliability
If user feedback is incorporated into handoff determination, then call quality and user experience are improved, but device complexity and processing requirements increase
Solution Approach 1:
The system implements partial action by selectively applying user feedback to adjust only the handoff threshold parameter rather than redesigning the entire handoff algorithm. This targeted approach incorporates personalization where it matters most (threshold determination) while leaving the core handoff mechanism intact, thereby improving call quality without proportionally increasing overall device complexity.
Solution Approach 2:
The invention focuses changes on a specific parameter (handoff threshold) rather than modifying the entire handoff system. By adjusting only this critical parameter based on user feedback, the system achieves improved call quality and personalization while minimizing the increase in device complexity, as the threshold adjustment is a localized change within the existing algorithm framework.
3Reliability
If handoff threshold is lowered to maintain call quality, then call reliability is improved, but network congestion increases due to more frequent handoffs
Solution Approach 1:
The system performs preliminary assessment of user feedback and call quality trends before initiating handoff threshold adjustments. By analyzing accumulated feedback data in advance, the system can determine the optimal threshold setting that maintains call quality while avoiding excessive handoffs, thereby preventing network congestion before it occurs rather than reacting after the fact.
Solution Approach 2:
The feedback mechanism enables the system to learn from the consequences of handoff decisions. By monitoring both call quality outcomes and network conditions following handoffs, the system can adjust thresholds to achieve the right balance - maintaining sufficient quality without triggering cascading handoffs that lead to network congestion, thus resolving the trade-off between reliability and network load.

AI summary
Examples are disclosed for user feedback to enable a handoff profile for a dual-mode hybrid mobile device. In some examples communication link handoff logic may be executed by the processor component to receive user feedback during a test voice call mediated with a call server, the user feedback pertaining to one or more Voice-over Internet Protocol (VoIP) communication link parameters for the communication link between the hybrid mobile device and the call server. The communication link parameters are correlated with a call quality threshold based on the user feedback and a handoff profile is established for the hybrid mobile device based on the call quality thresholds, the handoff profile operative to establish criteria for switching the VoIP communication link to a communication link over a different network.
