Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal configures a preferred wireless network based on personalized requirements, then the terminal can meet end user requirements, but the operator cannot optimize network resources effectively and service delivery may be affected
Solution Approach 1:
The patent introduces a network decision device as an intermediary between the terminal and the network. This device receives service information from the terminal, determines the preferred wireless network based on operator requirements, and sends control instructions to the terminal. This mediator resolves the contradiction by ensuring network-side optimization while maintaining terminal functionality.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal sends service information to the network decision device, which then provides control instructions back to the terminal. This closed-loop feedback ensures that the terminal's network selection aligns with operator requirements, resolving the contradiction between user needs and network optimization.
2Adaptability or versatility
If the terminal uses a wireless network configured by itself, then the terminal can satisfy its own service requirements, but the operator loses control over network resource allocation
Solution Approach 1:
The network decision device serves as an intermediary that maintains the terminal's adaptability to service requirements while ensuring operator control. It processes service information, determines appropriate networks based on operator policies, and instructs the terminal, thus bridging terminal autonomy and operator control.
Solution Approach 2:
The patent implements a dynamic network selection mechanism where the preferred network is determined based on real-time service information and operator requirements. This dynamic approach allows the system to adapt to changing conditions while maintaining operator control, resolving the contradiction between adaptability and automation.
3Productivity
If the operator implements centralized network control to optimize resources, then network resource optimization is achieved, but the system complexity increases
Solution Approach 1:
The patent extracts the network decision-making function from the terminal and places it in a separate network decision device. This extraction centralizes the complexity in a dedicated component while keeping the terminal simple, thus achieving network optimization without excessive terminal complexity.
Solution Approach 2:
The system is segmented into distinct functional components: the terminal, the network decision device, and the wireless network. This segmentation allows each component to have well-defined responsibilities, making the overall system manageable despite the centralized control requirements.

AI summary
Embodiments of this application provide a method for controlling a terminal to use a wireless network, a system, and a related device. The method includes: obtaining, by a network decision device, service information of a terminal, constructing network use indication information, and delivering the network use indication information to a network trigger device; and triggering, by the network trigger device based on the network use indication information, the terminal to use a wireless network corresponding to the service information. According to the method, an operator can assign, based on a service requirement of the operator, the terminal to use a specific wireless network, so that the terminal can use in time a wireless network that is consistent with a requirement of the operator. This helps improve network use efficiency for the operator, and can prevent a service of the terminal from being affected.
