Dual-Terminal Call Rejection Synchronization via Bluetooth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In one-number dual-terminal services, when a user rejects an incoming call on one terminal, the other terminal continues to ring, disturbing the user and reducing the overall experience.
Innovation Solution
Implement a method where associated terminals share a Bluetooth communication link to synchronize call rejection instructions, ensuring both terminals stop ringing when one receives a rejection command.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If simultaneous ringing mode is used for two associated terminals, then both terminals can receive calls, but when one terminal rejects the call the other continues to ring causing user disturbance
Solution Approach 1:
The patent merges the call control states of two associated terminals by establishing a Bluetooth communication link between them. When one terminal receives a call, it notifies the other terminal via Bluetooth, and when either terminal rejects the call, the rejection state is synchronized to the other terminal through Bluetooth, ensuring both terminals stop ringing simultaneously.
Solution Approach 2:
The patent implements feedback mechanism where terminals exchange call state information through Bluetooth communication. When a terminal rejects a call, it sends a rejection notification to the associated terminal via Bluetooth, which then stops its ringing based on this feedback information.
2Ease of operation
If one terminal rejects the call while the other continues to ring, then call rejection is possible, but user experience is reduced
Solution Approach 1:
The patent combines the call management functions of two terminals into a unified system through Bluetooth linkage. The call rejection operation on one terminal is mirrored on the other terminal, creating a coordinated call management experience that eliminates partial ringing and improves overall user experience.

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.
