Terminal Device Call Network Switching and Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current call network selection methods are not flexible enough, as users manually choose call networks, limiting options and potentially increasing costs and power consumption.
Innovation Solution
A method where a terminal device automatically detects the network types of both the calling and called parties and switches or rejects calls based on these networks to optimize communication, ensuring signal quality and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users manually select call networks, then call network selection is simple and direct, but flexibility is limited and costs may increase
Solution Approach 1:
The terminal device automatically detects network types and selects call networks without user intervention. The system self-determines whether to use WiFi, 2G, 3G, or 4G networks based on current network conditions, eliminating the need for manual user selection while providing flexible adaptability to different network environments
Solution Approach 2:
The system continuously monitors network type detection results and uses this feedback to dynamically adjust call network selection. When network conditions change or when the called party's network type is detected, the system automatically adjusts the call routing to optimize cost and performance
2Adaptability or versatility
If automatic network detection and switching is implemented, then call network flexibility improves and costs reduce, but device complexity increases
Solution Approach 1:
The terminal device performs automatic network type detection and call network selection without requiring complex user interface elements or manual configuration. The system autonomously manages multiple network types (WiFi, 2G, 3G, 4G) and switches between them based on detection results, simplifying the user experience while maintaining high adaptability
Solution Approach 2:
The terminal device is designed to support multiple communication networks (WiFi, 2G, 3G, 4G) simultaneously and can selectively use any of them for call services. This multi-functionality allows the device to adapt to various network conditions and optimize call costs without requiring separate devices or complex user management
3Adaptability or versatility
If terminal device uses multiple communication networks, then call options increase and flexibility improves, but power consumption increases
Solution Approach 1:
The system monitors network type detection results in real-time and uses this feedback to dynamically switch between different communication networks. When a more energy-efficient network becomes available or when network conditions change, the system automatically adjusts the active network, reducing power consumption while maintaining call flexibility
Solution Approach 2:
The terminal device dynamically selects and switches between different communication networks (WiFi, 2G, 3G, 4G) based on current network conditions and detection results. This dynamic approach allows the system to optimize power consumption by using the most energy-efficient available network while maintaining the capability to access multiple network types when needed

AI summary
A call switching method includes: when a first terminal device detects an input operation that is of initiating a call request to a second terminal device, or when a first terminal device receives a first call request that is initiated by a second terminal device by using a second-type communications network, detecting whether both the first terminal device and the second terminal device are in a first-type communications network; and when the first terminal device detects that both the first terminal device and the second terminal device are in the first-type communications network, initiating a second call request to the second terminal device by using the first-type communications network, or sending first prompt information to the second terminal device.
