Incoming Call Interface Sync Across Phone and PC Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices without mobile communication capability, such as personal computers and tablet computers, cannot make or answer calls, and existing solutions like Bluetooth-connected devices do not adequately provide call functionality or device information for incoming calls.
Innovation Solution
Establishing a short-distance communication connection between an electronic device with mobile communication capability and one without, allowing the latter to display device information and incoming call events from the former, including phone numbers, device names, and call marks to indicate synchronized calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an electronic device without mobile communication capability (e.g., PC or tablet) is connected to a mobile phone via Bluetooth, then the device can participate in call functions, but the user cannot identify which device is actually receiving the incoming call
Solution Approach 1:
The mobile phone acts as an intermediary device that receives incoming calls and forwards call information to the non-call device. The system introduces a call information forwarding mechanism where the mobile phone (first electronic device) receives incoming calls independently and synchronizes call events to the connected PC or tablet (second electronic device), enabling the non-call device to participate in calls while maintaining clear device identification through the intermediary's mediation
Solution Approach 2:
The system creates a copy of the call information from the mobile phone to the non-call device. When the mobile phone receives an incoming call, it generates a call event copy and transmits it via Bluetooth to the connected device. This copying mechanism allows the non-call device to display and manage call information without losing the ability to identify which device is actually receiving the call, as the call information is replicated rather than transferred
2Adaptability or versatility
If Bluetooth connection is used to enable call functionality on non-call devices, then call capability is provided, but device information display is insufficient
Solution Approach 1:
The system performs preliminary actions by establishing Bluetooth connectivity and device information synchronization before incoming calls occur. The mobile phone and non-call device exchange device identification information (device name, device type) in advance through the short-distance communication connection. This preliminary information exchange ensures that when calls are forwarded, the non-call device already has the necessary information to display which device is being called, eliminating information loss during the actual call event
3Reliability
If the first electronic device independently receives incoming calls, then call capability is maintained, but the user experience is degraded when multiple devices are involved
Solution Approach 1:
The system implements multi-functionality by enabling both the mobile phone and the non-call device to handle incoming calls. The mobile phone maintains its primary call reception function while the connected non-call device is also configured to receive and display call information. This universal approach allows users to answer calls on whichever device is more convenient, improving ease of operation while maintaining reliability through the mobile phone's primary call handling capability

AI summary
Embodiments of this application provide an incoming call display method and an electronic device, the method is performed by a first electronic device, and the method includes: when receiving a first incoming call from a third electronic device, in response to the first incoming call, presenting an incoming call interface of the first incoming call, where a calling party of the first incoming call is displayed in the incoming call interface of the first incoming call; and when receiving a second incoming call event sent from the second electronic device, in response to the second incoming call event, presenting an incoming call interface of a second incoming call. In the method, the first electronic device can display device information of the second electronic device that simultaneously receives an incoming call, thereby improving user use experience.
