Solution Overview

Problem

In distributed call scenarios involving multiple electronic devices, call conflicts arise due to simultaneous incoming calls and transfers, affecting user experience and device functionality.

Innovation Solution

A method and system for processing call conflicts by detecting specific scenarios and implementing prompt notifications, call handling, and network registration to manage call conflicts across devices with single or dual SIM capabilities, ensuring coordinated and secure call management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple electronic devices are added to a communication chain for distributed calling, then communication versatility is improved, but call conflict scenarios increase

Engineering Contradiction:
Improvecommunication versatilityVSAvoidcall conflict scenarios
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the call conflict processing by identifying different conflict scenarios (first scenario: incoming call during outgoing call; second scenario: incoming call during incoming call) and applying different handling strategies for each scenario across multiple devices in the magic ring group

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a server as an intermediary to coordinate call conflict processing. The server receives call requests, determines conflict scenarios, and instructs specific devices to answer or reject calls, thereby managing complexity across the distributed device network

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If call transfer between devices is enabled, then ease of operation is improved, but call conflict scenarios increase

Engineering Contradiction:
Improvecall transfer capabilityVSAvoidcall conflict scenarios
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements feedback mechanisms where devices report their call states to the server, and the server provides instructions back to devices. This feedback loop enables automatic call transfer and conflict resolution without requiring manual user intervention, thereby improving ease of operation while managing complexity centrally

Inventive Principle:
Principle #23Feedback

3Loss of information

If simultaneous incoming call notification is provided across devices, then information completeness is improved, but device interference increases

Engineering Contradiction:
Improveincoming call informationVSAvoiddevice interference
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by providing different notification behaviors to different devices based on their specific roles and states in the call conflict scenario. The server determines which devices should be notified and how, thereby providing complete information while minimizing unnecessary interference at each device location

Inventive Principle:
Principle #3Local quality

AI summary

This application provides a distributed call conflict processing method and system, an electronic device, and a storage medium, and belongs to the field of electronic technologies. The method is applied to a system including a first electronic device and a second electronic device, the first electronic device is near-field connected to the second electronic device, the first electronic device is a device having a telephone call function, and the first electronic device has a first SIM card. The first electronic device receives an incoming call event from a calling party, and obtains an incoming call SIM card identifier in the incoming call event; if a SIM card indicated by the incoming call SIM card identifier is the first SIM card, a status identifier of the first SIM card indicates that the first SIM card is occupied, and a status identifier of the second electronic device indicates that the second electronic device is occupied, the first electronic device sends the incoming call event to the second electronic device; and the second electronic device outputs a prompt of an incoming call conflict, to implement a prompt of a distributed call conflict and improve user experience.
