1Adaptability or versatility

If multiple devices access the internet simultaneously through 5G-NR networks, then network connectivity and service availability are improved, but network congestion increases leading to performance degradation

Engineering Contradiction:

Improvenetwork connectivityVSAvoidservice quality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the network device receives analytic data from the communication device about network conditions and performance metrics. Based on this feedback, the network device dynamically adjusts network settings including modulation schemes, routing protocols, and application settings to optimize performance and resolve congestion while maintaining service quality

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent applies dynamic adjustment of network parameters based on real-time analytic data. The network device continuously modifies modulation schemes, routing protocols, and application settings according to current network conditions, transforming the static network configuration into a dynamic system that adapts to changing traffic loads and maintains reliable service

Inventive Principle:

Principle #15Dynamics

Solution Approach 1:

The patent changes key network parameters including modulation schemes (e.g., QPSK, 16-QAM, 64-QAM, 256-QAM), routing protocols, and application settings based on analytic data. By dynamically adjusting these parameters, the system optimizes data transfer efficiency and maintains network throughput even when handling large data volumes

Inventive Principle:

Solution Approach 1:

The patent introduces an intermediary analytic data exchange mechanism between the communication device and network device. The communication device collects and analyzes network conditions, then transmits this analytic data to the network device, which uses it to adjust settings. This intermediary approach simplifies the overall system architecture while enabling dynamic optimization

Inventive Principle:
