5G Radio Unit Bandwidth Allocation for Guest Network Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deploying 5G networks is challenging for smaller service providers due to logistical issues in obtaining physical infrastructure, spectrum access, and maintaining control over shared networks, leading to inefficiencies and lack of flexibility.
Innovation Solution
A dynamic and flexible access model that allows guest network operators to use dedicated spectrum and radio resources through a provisioning plane, enabling them to instantiate their own virtualized network functions without managing physical resources, maintaining control over their services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If static bandwidth allocation is used, then network configuration is simple, but network efficiency is low and cannot adapt to changing traffic conditions
Solution Approach 1:
The patent implements dynamic bandwidth allocation where the network node continuously monitors QoS parameters and adjusts bandwidth allocation in real-time based on changing traffic conditions and user requirements, transitioning from static to dynamic control to resolve the contradiction between simplicity and efficiency
Solution Approach 2:
The patent establishes a feedback mechanism where QoS parameters are monitored, measured, and fed back to the network node, which then adjusts bandwidth allocation accordingly. This closed-loop control enables the system to adapt to changing conditions while maintaining manageable complexity through automated decision-making
2Productivity
If manual bandwidth configuration is used, then control is straightforward, but deployment time is long and scalability is limited
Solution Approach 1:
The patent enables self-service configuration where the network node automatically monitors QoS parameters, identifies allocation needs, and adjusts bandwidth without manual intervention. This automation significantly speeds up deployment while the system manages its own complexity through built-in monitoring and decision-making algorithms
Solution Approach 2:
The patent implements preliminary configuration of QoS parameters and allocation policies before actual bandwidth allocation occurs. This pre-configured framework enables rapid automated deployment while maintaining control, as the system only needs to execute pre-defined rules rather than making complex decisions in real-time
3Adaptability or versatility
If fixed QoS parameters are used, then configuration is easy, but service quality cannot adapt to varying network conditions
Solution Approach 1:
The patent transitions from fixed QoS parameters to dynamic parameters that automatically adjust based on real-time network conditions and user requirements. The system continuously monitors and adapts parameters such as latency, jitter, and bandwidth allocation, enabling high adaptability while managing complexity through automated parameter adjustment rather than manual reconfiguration

AI summary
Spectrum and radio resources associated with a 5G radio unit (RU) of a host network are dynamically allocated amongst one or more guest networks. A provisioning plane receives inputs from a guest network operator that identifies desired times, locations and/or frequency bands for desired network coverage. The provisioning plane responsively identifies bandwidth allocations that meet the requested parameters for exclusive use by the guest network. User equipment (UE) associated with each guest network maintains time and frequency synchronization with the host network, but otherwise limits its communications to the frequency bands allocated to the guest network. By dynamically obtaining physical radio and spectrum resources from a host provider and by scaling backend network capabilities using cloud resources, guest networks for any number of different purposes can be quickly deployed or modified as desired.
