Call Drop Notification Logic to Prevent Simultaneous Reconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile electronic devices often face disruptions from incoming calls in inappropriate situations, such as when the device is low on power or in areas with weak signal strength, leading to unintended disturbances, and existing solutions require manual intervention to mute or turn off the device.
Innovation Solution
A method and device that generate notifications when a call is accidentally disconnected, allowing users to determine whether to proactively establish a new call or wait for the other party to call back, thereby preventing simultaneous re-attempts to reconnect.

Engineering Contradiction Analysis
1Object-affected harmful factors
If users manually set mobile devices to mute incoming calls or turn off devices in advance, then disruptions from incoming calls are prevented, but user convenience and ease of operation deteriorate
Solution Approach 1:
The system performs preliminary detection of call quality parameters (signal strength, power status, network conditions) before an incoming call is established. Based on this preliminary assessment, the system proactively determines whether to allow or block the incoming call, preventing disruptions before they occur rather than requiring manual user intervention.
Solution Approach 2:
The system continuously monitors call quality parameters and provides feedback by automatically making decisions about incoming calls. The system uses real-time feedback from signal strength sensors, power status indicators, and network condition monitors to dynamically adjust call acceptance behavior without requiring user input.
2Reliability
If callers continue to call despite unknown callee conditions, then call completion rate improves, but harmful disruptions increase
Solution Approach 1:
The system performs preliminary assessment of call quality conditions before allowing incoming calls to connect. By evaluating signal strength, power status, and network conditions in advance, the system prevents calls from being established when conditions are unsuitable, thereby avoiding disruptions while maintaining reliable communication when conditions are favorable.
Solution Approach 2:
The system acts as an intermediary between the caller and callee by automatically filtering incoming calls based on detected conditions. This intermediary function allows the system to block potentially disruptive calls while permitting reliable calls, eliminating the need for callers to know callee conditions and preventing unintended disturbances.
3Speed
If users simultaneously call each other after call drop, then call re-establishment speed improves, but call failure rate increases
Solution Approach 1:
When a call is dropped, the system performs preliminary detection of the current network conditions and signal quality before initiating a reconnection attempt. Based on this preliminary assessment, the system intelligently determines the optimal timing and strategy for reconnection, avoiding simultaneous reconnection attempts that would cause failure while maintaining fast re-establishment when conditions permit.

AI summary
A method of handling a lost call and corresponding apparatus, whereby when a call between the first electronic apparatus and a second electronic apparatus is finished without having been hung up, determining, by the first electronic apparatus, whether the finished call was originally established by the first electronic apparatus; and in response to determining the finished call was originally established by the first electronic apparatus, generating, by the first electronic apparatus, a first notification for suggesting establishing another call with the second electronic apparatus by the first electronic apparatus; and in response to determining the finished call was not originally established by the first electronic apparatus, generating, by the first electronic apparatus, a second notification for suggesting waiting for the second electronic apparatus to establish the another call, wherein the first and second notifications are configured for preventing the first electronic apparatus and the second electronic apparatus from simultaneously calling each other.
