Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunication networks face inefficiencies in resource utilization and maintenance costs due to static network configurations that fail to adapt to dynamic traffic demands, leading to suboptimal performance and increased energy consumption.
Innovation Solution
A system and method to dynamically reconfigure network resources by detecting traffic demands, identifying available resources, and reallocating them to handle overload, using a processing system to manage network traffic distribution among distributed units (DUs) and centralized units (CUs) in 5G networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static network configurations are used, then network device complexity is reduced, but network resource efficiency deteriorates due to inability to adapt to dynamic traffic demands
Solution Approach 1:
The patent implements dynamic reconfiguration of network resources by allowing distributed units (DUs) to be dynamically selected and assigned to handle traffic demands. The system transitions from static network configurations to dynamic ones where network resources can be reallocated based on real-time traffic conditions, enabling the network to adapt to varying demands without manual intervention.
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring network traffic demands and resource availability statuses. Based on this feedback, the network controller dynamically adjusts resource allocation decisions, creating a closed-loop control system that optimizes network performance through iterative adjustments rather than fixed configurations.
2Productivity
If additional network resources are deployed to handle peak traffic, then network productivity is improved, but network device complexity and maintenance costs increase
Solution Approach 1:
The patent enables network resources to serve multiple functions by allowing any available DU to handle traffic from any cell. Instead of dedicating specific resources to specific cells, the system creates a universal resource pool where resources can be dynamically assigned based on demand, maximizing utilization without requiring additional infrastructure.
Solution Approach 2:
The system merges previously siloed cell-specific resources into a shared resource pool. By combining the capabilities of multiple DUs and allowing them to serve multiple cells, the system achieves better resource utilization and handles peak traffic without deploying additional network infrastructure.
3Use of energy by moving object
If network resources are statically allocated to each cell, then device complexity is minimized, but energy efficiency deteriorates due to idle resources during low traffic periods
Solution Approach 1:
The system dynamically adjusts resource allocation based on real-time traffic conditions. During low traffic periods, resources are released or reassigned to other cells that may need them, preventing idle resource consumption and improving energy efficiency. This dynamic approach replaces static allocation with adaptive resource management.

AI summary
Systems and methods to dynamically reconfigure network resources within telecommunication networks. One system may include a processing system configured to maintain a mapping that indicates characteristic(s) associated with each network resource of the telecommunications network. The processing system may be configured to detect that a first distributed unit (DU) of the telecommunications network is being overloaded. The processing system may be configured to determine, using the mapping, a resource availability status for a second DU included in the telecommunications network. The processing system may be configured to reconfigure the second DU to process the portion of the traffic demand of the first DU. The processing system may be configured to control transport of the portion of the traffic demand of the first DU such that the second DU processes the portion of the traffic demand.
