Dual-Terminal Incoming Call Rejection via Bluetooth Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual-terminal communication systems, when one user rejects an incoming call on one terminal, the other terminal continues to ring, causing user disturbance and reduced experience.
Innovation Solution
Implement a method where associated terminals share a SIM number and use Bluetooth communication to synchronize call rejection, ensuring both terminals stop ringing upon user input on one device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If simultaneous ringing mode is used for dual-terminal service, then both terminals can receive incoming calls, but when one terminal rejects the call, the other terminal continues to ring causing user disturbance
Solution Approach 1:
The patent implements a feedback mechanism where terminals exchange call state information through Bluetooth communication. When one terminal rejects an incoming call, it sends a rejection notification to the other terminal, which then stops ringing. This feedback loop ensures that call rejection actions are synchronized across both terminals, eliminating the harmful effect of continued ringing on the rejecting user.
2Ease of operation
If independent call handling is implemented on each terminal, then terminal operation simplicity is maintained, but call rejection synchronization between terminals is lost
Solution Approach 1:
The patent introduces Bluetooth communication as an intermediary channel between the two terminals. This intermediary enables the exchange of call state information (ringing status, answer/reject actions) without complicating the user interface or operation of individual terminals. Each terminal continues to operate simply with basic answer/reject buttons, while the Bluetooth intermediary ensures call state consistency across both devices.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents user disturbance by synchronizing call rejection across associated terminals, improving user experience.
Implementation Method 1
the first terminal sends indication information to the second terminal... the first terminal sends the indication information to the second terminal by using the Bluetooth communication link

AI summary
Embodiments of this application provide a method for responding to an incoming call, a corresponding terminal, and a communication system. The communication system includes a first terminal and a second terminal, the first terminal has a first subscriber identity module SIM number, the second terminal has a second SIM number, and the first SIM number is the same as the second SIM number. The first terminal and the second terminal simultaneously receive, from a network, an incoming call that is for the first SIM number and the second SIM number and that is from a third SIM number. In response to an incoming call rejection instruction that is entered by a user for the incoming call, the first terminal sends, to the network, a message used to reject the incoming call, and sends indication information to the second terminal, where the indication information is used to indicate the second terminal to send, to the network, a message used to reject the incoming call. The second terminal receives the indication information, and sends, to the network based on the indication information, the message used to reject the incoming call.
