1Quantity of substance
If multiple devices use 5G-NR network simultaneously for data-intensive applications, then network capacity and connectivity are improved, but network congestion increases and performance deteriorates
Solution Approach 1:
The system performs preliminary actions by proactively sharing analytic data between RAN and transport network devices before congestion fully develops. This enables the transport network to pre-adjust routing protocols, resource allocation, and network settings in anticipation of high-demand scenarios, preventing performance degradation rather than reacting to it after the fact.
Solution Approach 2:
The patent implements continuous feedback loops where analytic data flows bidirectionally between RAN and transport network devices. This feedback mechanism allows real-time monitoring of network conditions, enabling dynamic adjustments to routing, resource allocation, and modulation schemes based on actual traffic patterns and congestion levels, thereby maintaining reliability as device count increases.
2Productivity
If network settings are optimized for high data throughput, then application performance is improved, but network congestion increases
Solution Approach 1:
The system dynamically adjusts network settings based on real-time analytic data exchange between RAN and transport network devices. Routing protocols, resource allocation, and modulation schemes are not fixed but continuously adapted to balance throughput requirements with congestion prevention, allowing the network to optimize for high data transfer when needed while automatically scaling back to prevent congestion.
Solution Approach 2:
The patent utilizes parameter changes by modifying key network parameters such as routing protocol selections, resource allocation configurations, and modulation schemes based on shared analytic data. These parameter adjustments enable the network to switch between throughput-optimized modes and congestion-avoidance modes, effectively managing the trade-off between data productivity and congestion control.
3Reliability
If analytic data is shared between RAN and transport network devices, then network optimization is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by designing the analytic data sharing interface to serve multiple functions simultaneously. The same data exchange mechanism supports routing optimization, resource allocation, modulation scheme selection, and congestion management across different network conditions. This multi-functional approach reduces the need for separate specialized systems for each optimization task, thereby limiting the increase in overall system complexity.
