Automatic Network Access Card Switching for Dual-Card Smartphones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-card smartphones require users to manually switch between network access cards, leading to complex operations and poor user experience, especially when the network state of one card deteriorates or data limits are reached, resulting in potential extra fees and service disruptions.
Innovation Solution
An electronic device with a network access card switching method that automatically switches between installed cards based on preset conditions, such as signal strength, network standard, and data limits, to ensure continuous service and alert the user, thereby simplifying the switching process and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual card switching is required, then device complexity is reduced, but ease of operation deteriorates and user experience deteriorates
Solution Approach 1:
The system automatically monitors network states of multiple cards and performs switching without user intervention. The electronic device self-manages card selection based on preset conditions, eliminating the need for users to manually switch cards through menu settings.
Solution Approach 2:
The system pre-configures multiple network access cards with different operators and preset switching conditions. When conditions are met (e.g., network quality deteriorates or data limit is reached), the system automatically executes switching actions in advance to ensure continuous service.
2Ease of operation
If automatic switching is implemented, then ease of operation improves, but device complexity increases
Solution Approach 1:
The system continuously monitors network states of active cards and compares them against preset conditions. When conditions are met (signal strength threshold, network type, data usage limits), the system receives feedback and automatically triggers switching to alternative cards.
Solution Approach 2:
The electronic device integrates multiple network access cards from different operators and implements a unified management mechanism that handles all cards through the same automatic switching framework, regardless of operator or network type.
3Reliability
If manual switching is used, then reliability is maintained through user control, but loss of time increases due to switching operations
Solution Approach 1:
The automatic switching mechanism ensures continuous data service by pre-establishing backup cards and triggering instant switching when the active card fails or meets switching conditions, eliminating service interruptions and time loss associated with manual switching operations.
4Adaptability or versatility
If single card is used, then device complexity is reduced, but adaptability deteriorates when network conditions change
Solution Approach 1:
The system dynamically adjusts network access configuration based on real-time conditions. It automatically selects between multiple cards depending on network quality, signal strength, network type, and data usage status, making the device adaptable to changing network environments.

AI summary
A network access card switching method is performed by an electronic device on which a first network access card and a second network access card are installed. The first network access card is a default network access card of the electronic device. The network access card switching method includes determining that a user enables an intelligent network access card switching function, activating, by the electronic device, the first network access card, transmitting the data service using the first network access card, monitoring a network state of the first network access card in real time, and when determining that the network state of the first network access card meets a first preset condition, disconnecting the data service transmitted using the first network access card, activating the second network access card, and transmitting the data service by using the second network access card.
