Call Recording Continuity After Device Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The continuity of the call recording function is not guaranteed when a call is switched to another electronic device in a call continuity service.
Innovation Solution
An electronic device is configured to generate and store recording data including user and counterpart's voice data, and upon detecting a call switch to another device, continues the recording function by storing additional data in the memory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the recording function is performed by the electronic device itself during a call, then the recording can be made locally, but the continuity of the recording function is not guaranteed when the call is switched to another electronic device
Solution Approach 1:
The patent implements a cloud server that provides universal call recording service across multiple electronic devices. The server receives call data from any registered device and stores it centrally, allowing the recording function to be accessed universally from any device in the group, thus ensuring continuity during call switching without requiring complex inter-device coordination mechanisms
Solution Approach 2:
The patent introduces a cloud server as an intermediary between electronic devices for call recording. Instead of devices directly recording and transferring data to each other during call switching, the server mediates by receiving, storing, and managing call data centrally, simplifying the system while ensuring recording continuity across device transitions
2Ease of operation
If the call is switched to another electronic device through call continuity service, then the user can continue the call without interruption, but the recording function may be interrupted
Solution Approach 1:
The patent implements a system where the cloud server automatically continues recording call data after device switching without requiring user intervention. The server self-manages the recording stream by continuously receiving call data from the new device and maintaining the recording session, ensuring both call continuity and recording continuity through automated service
3Adaptability or versatility
If the recording function is tied to a specific electronic device, then the device can independently perform recording, but the recording cannot continue when the device changes
Solution Approach 1:
The patent creates a universal recording service through the cloud server that is not tied to any specific device. Any electronic device in the registered group can initiate and access recording services, and the server maintains continuous recording across device transitions, providing both device independence and recording continuity

AI summary
An electronic device according to various embodiments comprises: a display; a communication module; a microphone; a memory; and a processor operatively connected to the display, the communication module, the microphone, and the memory, wherein the processor may be configured to: call a first external device through the communication module; when a call recording function is started on the basis of a user input, generate first recording data including user voice data inputted through the microphone and the other party's voice data received from the first external device through the communication module, and store the first recording data in the memory; detect a switch of the call with the first external device to a second external device which is connected to the electronic device through a call continuity service; and store, in the memory, second recording data including the other party's voice data and external voice data received from the second external device through the communication module.
