Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile terminal relies on a single mobile network for communication, then the device complexity is low, but the connectivity reliability is insufficient for safety-critical applications
Solution Approach 1:
The patent segments the network selection process by dividing it into two distinct components: a network component that collects and analyzes communication performance information from multiple networks, and a mobile terminal that executes communication based on control information received from the network component. This segmentation allows the terminal to rely on multiple networks without increasing its own complexity, as the analysis and decision-making functions are offloaded to the network component.
Solution Approach 2:
The network component acts as an intermediary between multiple mobile networks and the mobile terminal. It collects communication performance information from various networks, determines the optimal network for communication, and provides control information to the terminal. This intermediary approach enables the terminal to achieve high connectivity reliability through multi-network support without bearing the complexity of direct multi-network management.
2Reliability
If the mobile terminal dynamically switches between multiple mobile networks, then the connectivity reliability improves, but the ease of operation deteriorates due to automated network management requirements
Solution Approach 1:
The system implements self-service through automated network management. The network component autonomously collects communication performance information from multiple networks, evaluates the data, determines the optimal network for communication, and provides control information to the terminal without requiring user intervention. This automation maintains ease of operation while achieving high connectivity reliability through dynamic network switching.
Solution Approach 2:
The network component continuously collects communication performance information from multiple mobile networks and uses this feedback to dynamically determine the optimal network for communication. The control information is provided to the terminal based on real-time network conditions, enabling adaptive network switching that maintains reliability without requiring user input. The feedback loop ensures the system responds to changing network conditions automatically.
3Measurement precision
If communication performance information is collected from multiple mobile networks, then the measurement precision of network selection improves, but the loss of time increases due to data collection and analysis requirements
Solution Approach 1:
The network component performs preliminary actions by continuously collecting and pre-processing communication performance information from multiple mobile networks before a communication request is made. This advance preparation ensures that when the terminal needs to establish communication, the network component can quickly determine the optimal network based on pre-analyzed data, reducing the time penalty associated with collecting and analyzing network information.
