Solution Overview

Problem

Conventional dual SIM-card and dual operating system terminals fail to ensure data security between two operating systems while processing incoming calls from two SIM cards, leading to potential data leakage.

Innovation Solution

A method and apparatus for a dual SIM-card and dual operating system terminal that detects incoming calls on both operating systems, partitions the display screen into separate regions, and uses event triggering to display and manage incoming calls independently, ensuring no data sharing or interference between the operating systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If both operating systems share the address book and call records to process incoming calls in the same user interface, then the ease of operation is improved, but the data security between the two operating systems deteriorates

Engineering Contradiction:
Improveease of operationVSAvoiddata security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent divides the user interface into separate display regions for each operating system. When both OS have incoming calls, the screen is partitioned into a first display region for the first OS and a second display region for the second OS, allowing independent display and processing of calls while maintaining data security through spatial separation.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the terminal displays only one incoming call information on the screen when both SIM cards have incoming calls, then the data security is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvedata securityVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent transitions from a single-display-mode approach to a multi-region display approach by adding the dimension of spatial partitioning. Instead of showing only one call or switching between OS, the system utilizes different display regions simultaneously to present multiple incoming calls from different OS, enhancing usability while preserving security.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If the terminal processes incoming calls from two SIM cards in the same user interface, then the productivity is improved, but the data security deteriorates due to shared data between operating systems

Engineering Contradiction:
ImproveproductivityVSAvoiddata security
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements segmentation by creating distinct display regions for each operating system's incoming calls. The first OS displays its incoming call in the first display region, while the second OS displays its incoming call in the second display region, enabling parallel processing of calls from both SIM cards while maintaining data isolation and security.

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed is an incoming call processing method for a dual-card and dual-system terminal. A first operating system receives an incoming call of a first SIM card; a second operating system triggers an event to notify the first operating system of an incoming call of a second SIM card upon receiving the same; the first or second operating system partitions a display screen into first and second display regions; and the first operating system displays an operating interface of the SIM card corresponding to the first operating system in the first display region, and triggers an event to notify the second operating system of display in the second display region; or the second operating system displays an operating interface of the SIM card corresponding to the second operating system in the second display region, and triggers an event to notify the first operating system of display in the first display region.
