Seamless Call Handoff via Proximity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods of transferring a communications exchange, such as a phone call, often result in noticeable interruptions or disruptions, requiring users to end the current call and initiate a new one or place it on hold, which is inconvenient and can lead to lost sales or customer dissatisfaction.
Innovation Solution
A method and system that allow seamless transfer of a communications exchange by automatically detecting a second communications device in close proximity using RF signals, enabling a call handoff without user intervention, utilizing technologies like infrared, wireless USB, or Bluetooth for detection and transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional call transfer methods are used (ending current call and initiating new call, or placing on hold and manually transferring), then the call can be transferred between devices, but the natural flow of communication is disrupted causing interruptions and user inconvenience
Solution Approach 1:
The system performs preliminary actions by automatically detecting nearby devices and pre-establishing transfer conditions before the user initiates a transfer. The mobile telephone proactively identifies available communication devices in proximity and prepares transfer parameters, so when transfer is needed, the handoff can occur seamlessly without manual intervention or communication disruption.
Solution Approach 2:
The call transfer process becomes self-service through automatic device detection and transfer execution. The system autonomously monitors for nearby communication devices, automatically initiates handoff procedures when conditions are met, and completes the transfer without requiring user action to end calls, place them on hold, or manually dial new numbers, thereby maintaining communication continuity.
2Adaptability or versatility
If manual call transfer procedures are implemented (placing call on hold and performing series of steps), then call transfer is achieved, but user time is lost and business productivity is reduced
Solution Approach 1:
The patent replaces manual mechanical operations (pressing buttons, dialing numbers, following transfer procedures) with automatic electronic detection and signal-based handoff. The mobile telephone uses automated device detection mechanisms and electronic signal exchange to transfer calls, eliminating the need for users to perform time-consuming manual steps while maintaining full transfer capability.
Solution Approach 2:
The system introduces an intermediary automatic handoff mechanism that mediates between the current communication device and the target device. This intermediary process automatically manages the transfer sequence, device coordination, and connection switching, reducing the time users would otherwise spend on manual transfer operations while ensuring reliable call transfer.
3Reliability
If automatic device detection and seamless handoff are implemented, then communication continuity is maintained, but device complexity and detection requirements increase
Solution Approach 1:
The mobile telephone leverages its existing multi-functional capabilities (device detection, wireless communication, signal processing) to perform call transfer operations. By utilizing the universal detection and communication functions already present in modern mobile devices, the system achieves seamless handoff without adding significant complexity, as the same hardware and software infrastructure supports multiple functions including transfer operations.

AI summary
Methods and systems for transferring a communications exchange using a mobile handset (128) are described. A radio frequency (RF) signal is transmitted from a mobile handset to a base station to provide a communications exchange. The communications exchange exists between the mobile handset and a first communications device (104). The mobile handset automatically detects a second communications device when it is in close proximity to the second communications device. The second communications device is capable of receiving a call handoff. If the mobile handset is in close proximity to the second communications device, then a transfer request including information associated with the second communications device is received from the second communications device. The transfer request is accepted and the communications exchange is seamlessly transferred to the second communications device form the mobile handset.
