Dynamic Network Resource Allocation for Congestion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network congestion occurs when the number of user devices accessing services via a particular frequency allocation exceeds a threshold, leading to inefficient resource allocation and potential service disruptions in radio access networks.
Innovation Solution
The system dynamically generates and transmits allocation information to user devices, allowing them to identify the appropriate frequency bands and allocations for accessing applications and services, enabling the network to allocate resources effectively and prevent congestion by switching between unicast and multicast traffic as needed.

Engineering Contradiction Analysis
1Productivity
If multiple user devices access services via the same frequency allocation, then resource utilization efficiency is improved, but network congestion occurs when the number of devices exceeds a threshold
Solution Approach 1:
The patent implements dynamic frequency allocation where the network device monitors traffic conditions and adjusts frequency band assignments in real-time. When congestion is detected on a frequency allocation, the system dynamically reassigns affected user devices to alternative frequency bands, transforming the static resource allocation into a dynamic adaptive system that prevents congestion while maintaining high resource utilization.
2Reliability
If the network allocates dedicated frequency bands to each user device, then network performance is maintained, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent makes frequency bands universal by allowing the same frequency allocation to be shared among multiple user devices simultaneously. The system assigns a first frequency band to a first user device and a second frequency band to a second user device, where these frequency bands can be dynamically reassigned based on traffic conditions, enabling each frequency resource to serve multiple functions and multiple users rather than being dedicated to a single device.
3Reliability
If the network dynamically reallocates frequency bands based on traffic conditions, then network congestion is prevented, but system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the network device continuously monitors traffic conditions on frequency allocations and uses this feedback to make intelligent reassignment decisions. The system detects when a frequency allocation is experiencing congestion and automatically responds by reassigning affected user devices to alternative frequency bands, creating a closed-loop control system that manages complexity through adaptive response rather than exhaustive pre-planning.

AI summary
A device may receive, from a base station, information that identifies traffic conditions within the base station; and may assign one or more different frequency bands to each of one or more applications being provisioned, by the base station, to one or more user devices based on the information that identifies the traffic conditions within the base station. The device may also generate allocation information that identifies how the different frequency bands are allocated to each of the applications; and transmit, via the base station, the allocation information to the user devices, where transmitting the allocation information allows a user device to identify a frequency band with which to obtain an application.
