Solution Overview
Problem
Existing network switching strategies in smart terminal devices fail to consider network slicing conditions, leading to suboptimal user experience when switching between Wi-Fi and cellular networks, especially in environments where Wi-Fi signal strength and speed are inferior to cellular networks.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal device switches to Wi-Fi network based on default strategy, then the network switching is simple and fast, but the network connection quality and speed deteriorate in environments where Wi-Fi signal is poor
Solution Approach 1:
The patent changes the network switching decision parameters from simple signal strength checks to comprehensive network slice information evaluation. The terminal device monitors network slice information, network type, and service requirements to dynamically adjust switching decisions, thereby improving connection quality while maintaining reasonable switching complexity
Solution Approach 2:
The patent implements dynamic network switching strategies that adapt to changing network conditions. The terminal device continuously monitors network slice information and adjusts switching behavior in real-time based on current network environment, service requirements, and slice availability, transforming static default switching to dynamic condition-based switching
2Device complexity
If the terminal device always prioritizes Wi-Fi network, then the network switching strategy is simple to implement, but the user experience deteriorates when cellular network provides better service quality
Solution Approach 1:
The patent introduces network slice information as a key parameter in switching decisions. Instead of always prioritizing Wi-Fi, the terminal evaluates network slice characteristics, service requirements, and current network conditions to determine the optimal network, thereby improving transmission speed while maintaining manageable complexity through structured decision criteria
Solution Approach 2:
The patent segments the network switching decision into multiple evaluation dimensions: network slice information, network type, service requirements, and signal quality. This segmentation allows the system to consider multiple factors without creating excessive complexity, as each dimension can be evaluated independently and combined through weighted decision logic
3Reliability
If the terminal device monitors network slice information and switches to data network accordingly, then the network connection quality improves, but the device complexity increases
Solution Approach 1:
The patent leverages existing multi-functional capabilities of the terminal device: the same monitoring mechanisms used for general network status detection are extended to monitor network slice information, and the existing network switching framework is enhanced to incorporate slice-based decision logic. This universal approach improves connection quality without requiring entirely new separate systems
Solution Approach 2:
The patent performs preliminary monitoring and evaluation of network slice information before actual network switching occurs. The terminal device continuously gathers and analyzes network slice data in advance, preparing switching decisions based on predicted optimal networks, which reduces the complexity of real-time switching while maintaining high connection quality
