Ultrasound Session Handover for Seamless Cross-Device Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems lack the ability to seamlessly transfer ongoing sessions between devices due to the inability to determine device proximity, leading to disruptions and the need for manual reinitiation of sessions.
Innovation Solution
Implementing a proximity-based session handover system that utilizes short-range signals, such as ultrasonic, IR, UWB, NFC, DSRC, or Bluetooth, to detect device proximity and transfer ongoing sessions to a second device, ensuring continuity without interruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional communication systems are used without proximity detection, then device complexity is reduced, but session continuity is disrupted when switching devices
Solution Approach 1:
The patent introduces a server as an intermediary that coordinates session handover between devices. The server receives proximity information, determines target devices, and manages the session transfer process, thereby maintaining session continuity without requiring complex direct device-to-device coordination
Solution Approach 2:
The system segments the session handover process into distinct phases: proximity detection phase, target device determination phase, and session transfer phase. This segmentation allows each component to be independently managed and reduces overall system complexity while ensuring reliable session continuity
2Loss of time
If manual session reinitiation is required when switching devices, then device complexity is minimized, but loss of time increases due to session interruption
Solution Approach 1:
The system performs preliminary actions by detecting device proximity and determining target devices before the user actually needs to switch devices. The server proactively prepares for session handover by identifying suitable target devices in advance, eliminating session interruption and time loss
Solution Approach 2:
The system implements feedback mechanisms where the server continuously monitors device proximity information and automatically triggers session handover when appropriate conditions are met. This feedback loop enables seamless automatic handover without requiring manual user intervention, reducing both time loss and operational complexity
3Measurement precision
If short-range signals are used to detect device proximity, then session transfer accuracy is improved, but use of energy increases due to continuous signal monitoring
Solution Approach 1:
The system employs periodic action by having devices transmit short-range signals at specific intervals rather than continuously. The server receives these periodic proximity signals and determines target devices based on the timing and frequency of signal reception, achieving accurate proximity detection while minimizing energy consumption through scheduled rather than continuous transmission
