Solution Overview

Problem

The need for manual user selection of a SIM card during operations in multi-SIM terminal devices is cumbersome and detracts from user experience.

Innovation Solution

A method and device that automatically selects the appropriate SIM card for an application based on the display region where its icon is located, associating the SIM card with the display region to streamline operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual SIM card selection is implemented for each application operation, then the terminal device can ensure correct SIM card usage, but the user operation complexity increases and user experience deteriorates

Engineering Contradiction:
Improvecorrect SIM card usageVSAvoiduser operation complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies preliminary action by pre-establishing the association between display regions and SIM cards before application operations occur. The system pre-configures which SIM card corresponds to which display region, so that when an application needs to perform SIM card-based operations, the correct SIM card is automatically selected based on the pre-established mapping, eliminating the need for manual user selection at the time of operation.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple SIM cards are installed in the terminal device, then the device can access multiple wireless networks, but the complexity of SIM card selection and management increases

Engineering Contradiction:
Improvemulti-network access capabilityVSAvoidSIM card selection complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the terminal device into distinct display regions, with each region associated with a specific SIM card. This spatial segmentation creates clear boundaries and mappings between display areas and SIM cards, making the multi-SIM management system more organized and easier to manage by visually separating the functions of different SIM cards across different display regions.

Inventive Principle:
Principle #1Segmentation

AI summary

Embodiments of the present disclosure provide a SIM card selection method and a terminal device. The method includes: receiving a first input of a user to a target application; and controlling, in response to the first input, the target application to perform a first operation based on a first SIM card, wherein the first SIM card is a SIM card associated with a first display region, and the first display region is a display region in which an icon of the target application is located.
