Dual-SIM Internet Access Switching by Application Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-card mobile phones can only use one SIM card for internet access at a time, leading to inefficient data traffic charging and poor user experience due to the need to manually switch SIM cards for different applications, resulting in potential excess charges for general data usage.
Innovation Solution
Implement a smart dual-card internet access function that automatically switches between SIM cards based on application associations, allowing different applications to use separate data packages, reducing the need for manual SIM card switching and optimizing data traffic charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a terminal sends a network access request to multiple access networks simultaneously, then access speed is improved, but power consumption increases and access reliability deteriorates due to unsuccessful access attempts
Solution Approach 1:
The terminal performs preliminary actions by selecting a target access network based on pre-established selection criteria (signal strength, network type, historical data) before attempting access. This preliminary selection process prevents random or simultaneous access attempts to multiple networks, thereby improving access reliability while maintaining efficient access speed through informed target selection.
2Stability of the object's composition
If a terminal selects an access network with stronger signal strength, then connection stability is improved, but access time increases due to sequential selection process
Solution Approach 1:
The terminal applies partial action by evaluating only the most relevant network parameters (signal strength, network type) rather than exhaustively analyzing all possible networks. The selection criteria are designed to identify suitable networks quickly without requiring complete evaluation of every available network, thus reducing access time while still achieving stable connections through targeted selection.
3Reliability
If a terminal uses complex selection criteria for network selection, then access reliability is improved, but device complexity increases
Solution Approach 1:
The network selection mechanism is segmented into distinct functional modules: signal strength detection module, network type identification module, selection criteria evaluation module, and target network determination module. Each module handles a specific aspect of the selection process, making the overall complex system manageable and maintainable while achieving reliable access through coordinated module operation.

AI summary
Disclosed are an internet access method, an electronic device, and a chip. When a first application and a second application are installed on the electronic device, a first SIM card is a default internet access card, the first application is associated with the first SIM card, and the second application is associated with a second SIM card. The internet access method specifically includes: when the first application and/or the second application run/runs, using the first SIM card to perform a data service; enabling a smart dual-card internet access function in response to a first operation, so that the smart dual-card internet access function is enabled, when the first application runs, using the first SIM card to perform a data service, and when the second application runs, using the second SIM card to perform a data service.
