Engineering Contradiction Analysis
1Productivity
If conventional UPF selection method is used considering only regional information and policy information, then device complexity is reduced, but data transmission efficiency deteriorates due to performance delay in signaling procedure
Solution Approach 1:
The patent changes the selection parameters from static regional and policy information to dynamic state information including signal quality, load, and communication interface status. This allows the UPF selection to adapt to real-time network conditions, improving data transmission efficiency while managing complexity through automated parameter collection and evaluation
Solution Approach 2:
The patent implements a feedback mechanism where the network entity continuously collects state information from communication interfaces between UPFs and control plane devices. This feedback loop enables the selection process to respond to changing network conditions, optimizing data transmission efficiency through iterative evaluation of signal quality and load parameters
2Productivity
If more state information is collected and considered for UPF selection, then data transmission efficiency is improved, but measurement and detection difficulty increases
Solution Approach 1:
The patent uses a multi-functional network entity that performs multiple tasks including collecting state information, determining signal quality, evaluating load conditions, and making UPF selection decisions. This consolidation of functions into a single entity simplifies the overall system architecture while enabling comprehensive consideration of multiple state parameters for optimized data transmission
3Speed
If UPF selection is optimized for high-speed packet processing, then processing speed is improved, but signaling procedure delay increases due to additional state information collection
Solution Approach 1:
The patent performs preliminary collection and evaluation of state information before UPF selection is finalized. By pre-collecting signal quality, load, and communication interface status data, the system can make faster selection decisions without requiring extensive real-time measurement during the signaling procedure, thus reducing overall delay while maintaining high processing speed
