Solution Overview
Problem
Challenges exist in providing reliable and high-quality service for devices using 5G-NR technology, particularly when multiple devices access the internet simultaneously, leading to network congestion and reduced performance for applications with large data demands.
Innovation Solution
Implementing application programming interfaces (APIs) and subscription services that enable 5G-NR networks to share analytic data across radio access, transport, and core networks, allowing devices to adjust network settings for improved performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices access the internet simultaneously through 5G-NR network, then network connectivity and service availability are improved, but network congestion increases and performance deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where network devices monitor traffic conditions and performance metrics, then adjust network parameters dynamically. The system collects data on network congestion, device performance, and traffic patterns, processes this information through analytics functions, and uses the results to optimize routing, allocate resources, and control admission of new connections, thereby maintaining performance despite high connectivity demands
Solution Approach 2:
The patent applies dynamic adjustment of network parameters based on real-time conditions. Network devices continuously modify routing algorithms, resource allocation policies, and quality of service parameters in response to changing traffic patterns and congestion levels, enabling the network to adapt its behavior to maintain performance under varying load conditions
2Productivity
If devices with large data demands are served, then data transfer capability is improved, but network congestion worsens and overall service quality deteriorates
Solution Approach 1:
The patent implements differential quality of service policies where different network resources and service levels are allocated to different devices or traffic types based on their specific requirements. High-priority traffic such as real-time applications receives guaranteed bandwidth and lower latency treatment, while best-effort traffic receives remaining capacity, allowing the network to serve diverse data demands without uniform degradation
Solution Approach 2:
The patent applies selective resource allocation where network capacity is preferentially allocated to traffic types or devices that require it most for maintaining service quality. During congestion, the system may limit or throttle certain non-critical data transfers while ensuring critical services maintain adequate performance, effectively using partial action on select traffic flows to preserve overall network quality

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.
