Host Device Telephone Call Sharing via Wi-Fi Direct
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems do not efficiently allow users to seamlessly share telephone calls between multiple electronic devices, particularly in scenarios where a primary device is not readily accessible, and there is a need to integrate additional devices into ongoing conversations without disrupting the call connection.
Innovation Solution
A host electronic device equipped with a transceiver and wireless communication module that establishes a direct Wi-Fi Direct connection with participant devices, enabling concurrent processing and presentation of call data across devices, allowing for automatic forwarding of audio and video data between the host, participant, and outside devices, thereby facilitating shared telephone calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a primary device is used to place and receive telephone calls, then the call connection is established, but the user cannot seamlessly share the call with additional devices when the primary device is not accessible
Solution Approach 1:
The patent uses Wi-Fi Direct as an intermediary communication channel between the primary device and additional devices. When the primary device is not accessible, the additional devices can establish direct peer-to-peer connections through Wi-Fi Direct, allowing call sharing without requiring the primary device to be physically present or actively managing the connection.
Solution Approach 2:
The system allows multiple electronic devices (smartphones, tablets, laptops) to function as call participants through a single phone number. Each device can independently initiate or receive calls, and the system dynamically routes call data between devices based on availability and user selection, making the call system universally accessible across different device types.
2Adaptability or versatility
If additional devices are connected to the primary device via Wi-Fi Direct, then call sharing is enabled, but the system complexity increases
Solution Approach 1:
The system implements automatic device discovery and connection establishment through Wi-Fi Direct. When a call is initiated or received, the system automatically identifies available devices, presents them to the user through a graphical interface, and manages the data routing between devices without requiring manual configuration or complex connection management by the user.
Solution Approach 2:
The system pre-establishes Wi-Fi Direct connections between devices before call sharing is needed. Devices are discovered and paired in advance, so when call sharing is required, the connection infrastructure is already in place, reducing the complexity of real-time connection management during active calls.
3Productivity
If call data is forwarded between multiple devices, then seamless call sharing is achieved, but real-time data transfer reliability must be maintained
Solution Approach 1:
The call data stream is segmented and routed through different paths depending on device availability. The system divides the call participation into separate data channels between the primary device and each additional device, allowing independent management of each connection. If one device disconnects, the segmentation allows the call to continue through remaining active devices without compromising overall reliability.
Solution Approach 2:
The system implements feedback mechanisms to monitor the status of Wi-Fi Direct connections and call data transfer quality. When connection quality degrades or devices become unavailable, the system receives feedback and dynamically adjusts the data routing, switching between devices to maintain reliable call sharing. The graphical interface provides visual feedback to users about active connections and call status.

AI summary
A host electronic device is configured to share a telephone call with a participant electronic device. The host electronic device includes a transceiver, a wireless communication module and a controller. The controller is configured to: establish a direct wireless connection with the participant electronic device; process and present incoming call data received from an outside device through a speaker and/or a display device at the host electronic device; forward the incoming call data to the participant electronic device using the direct wireless connection for presentation of the incoming call data through a speaker and/or a display device at the participant device; receive participant call data from the participant electronic device using the direct wireless connection; process and present the received participant call data through a speaker and/or display device at the host electronic device; and forward the participant call data to the outside device.
