Engineering Contradiction Analysis
1Quantity of substance
If multiple devices access the internet simultaneously through 5G-NR network, then network capacity and connectivity are improved, but network congestion increases and performance degrades
Solution Approach 1:
The patent implements dynamic network settings adjustment by allowing devices in the transport network to modify modulation schemes, routing algorithms, and device selection based on real-time analytic data from the radio access network. This dynamic adaptation enables the network to optimize performance metrics (latency, bandwidth, throughput) in response to changing traffic conditions caused by multiple simultaneous device connections.
Solution Approach 2:
The system establishes a feedback loop where analytic data from the radio access network is continuously shared with transport network devices through exposed interfaces. This feedback mechanism allows transport network devices to monitor network conditions and adjust their operations accordingly, resolving the contradiction between supporting many devices and maintaining reliable performance.
2Adaptability or versatility
If applications with large data demands are supported, then service capability is improved, but network congestion is exacerbated
Solution Approach 1:
The patent enables parameter changes in network operation by allowing transport network devices to adjust modulation schemes and routing algorithms based on analytic data. These parameter adjustments optimize network resource allocation for different application types, enabling high-capacity applications to be supported while managing their impact on overall network congestion through intelligent resource management.
3Productivity
If network settings are dynamically adjusted to improve performance, then network efficiency is improved, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism where the radio access network device collects and processes analytic data, then exposes this information through standardized interfaces to transport network devices. This intermediary approach simplifies the overall system by centralizing data collection and presentation, allowing transport network devices to adjust settings based on pre-processed information rather than requiring complex direct monitoring and control mechanisms.

AI summary
Apparatuses, systems, and techniques including APIs, subscription services, and controllers to enable one or more fifth generation new radio (5G-NR) networks to share information. For example, a processor comprising one or more circuits can perform an API or subscription service to cause a device in a radio access network (RAN) to share its analytic data with a device in a transport network, and said device in said transport network can use said analytic data to adjust its network settings to improve performance.
