Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If end devices perform NTN search and connection procedures, then connectivity to non-terrestrial networks is achieved, but resource utilization and battery consumption increase
Solution Approach 1:
The network side performs NTN search procedures in advance before the end device needs to establish connectivity. The network determines available NTN cells and provides this information to the end device, eliminating the need for the end device to perform resource-intensive search procedures itself, thereby reducing battery consumption while maintaining connectivity reliability.
Solution Approach 2:
The network acts as an intermediary that performs the NTN search and measurement functions on behalf of the end device. The network measures reference signal received power (RSRP) and other parameters, then provides this information to the end device for connection decisions, shifting the computational and energy burden from the end device to the network infrastructure.

3Reliability
If end devices continuously search for terrestrial networks, then connectivity is maintained, but time is lost during search procedures
Solution Approach 1:
The network performs NTN search and cell determination in advance, so when the end device needs to establish connectivity, the information is already ready. This eliminates continuous searching and reduces the time the end device would otherwise spend searching for available networks, while maintaining reliable connectivity through pre-determined network options.
