Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If predetermined network priority information is used to switch between WLAN and LTE networks, then the switching rule is simple and deterministic, but the communication service quality deteriorates in enclosed environments where LTE network quality is poor
Solution Approach 1:
The patent implements dynamic network switching by continuously monitoring signal measurement parameters from both WLAN and LTE networks and automatically selecting the network with better signal quality. This dynamic approach replaces the static predetermined priority mechanism, allowing the system to adapt to changing network conditions in real-time and maintain reliable communication service quality in enclosed environments where LTE may be poor.
Solution Approach 2:
The patent introduces feedback mechanisms by periodically receiving signal measurement parameters from both networks and using this feedback information to make intelligent switching decisions. The system compares signal qualities and adjusts network selection based on actual performance, ensuring reliable communication service while maintaining operational simplicity through automated decision-making.
2Adaptability or versatility
If WLAN network is always prioritized for IMS communication service, then WLAN network coverage is utilized more effectively, but network connection efficiency decreases when LTE network provides better signal quality
Solution Approach 1:
The patent implements dynamic network switching by continuously monitoring signal measurement parameters from both WLAN and LTE networks and automatically selecting the network with better signal quality. This dynamic approach replaces the static predetermined priority mechanism, allowing the system to adapt to changing network conditions in real-time and maintain reliable communication service quality in enclosed environments where LTE may be poor.
Solution Approach 2:
The patent changes the selection parameter from fixed network priority to dynamic signal quality measurement. By comparing signal measurement parameters in real-time, the system optimizes network connection efficiency by selecting the network with superior signal quality, whether WLAN or LTE, thereby improving productivity without sacrificing adaptability.
3Device complexity
If network switching relies on predetermined information, then the switching logic is simple, but the time for connecting to network increases and network connection efficiency decreases
Solution Approach 1:
The patent performs preliminary actions by continuously monitoring and evaluating signal measurement parameters from both WLAN and LTE networks in advance. This proactive approach allows the system to have network quality information ready before switching is needed, reducing connection time and improving efficiency without significantly increasing switching logic complexity through automated comparison and selection algorithms.
Solution Approach 2:
The patent implements self-service by enabling the terminal to autonomously evaluate network signal qualities and make switching decisions without complex external control. The terminal automatically compares signal measurement parameters and selects the optimal network, reducing connection time and improving efficiency while keeping switching logic relatively simple through self-contained decision-making capabilities.
